A hundred years’ review of Hong Kong literature: how did the literati write about this city in the past 100 years?

Today is the 25th anniversary of Hong Kong’s return to the motherland.

Concerned about Hong Kong’s society and culture, we can’t avoid Hong Kong’s literature.

In 1921, Shuangsheng magazine was founded, and people began to write novels in semi-vernacular with Hong Kong as the background. Until this year, Hong Kong, China’s modern literature has gone through one hundred years.

In Hong Kong, where pop music and movies are the main cultural products, literature does not seem to be particularly concerned. However, as a unique existence in China’s modern and contemporary literature, Hongkong literature has its own style and charm.

For the motherland, Hong Kong literature is a "surprise".

Wang Dewei, a professor of East Asian Department of Harvard University, once said: "Located in the south, this land was once a place where colonial forces were located, and it was difficult to form a stable literary production field with political swings and mixed cultures." At the same time, "the rapid consumption transformation from economic capital to cultural capital" has set many obstacles for Hong Kong literature to form its own style and characteristics.

However, looking back over the past hundred years, several generations of writers "have created one legend after another with their hard work."

For those writers who live in Hong Kong and create Hong Kong literature, the significance of writing Hong Kong literature lies in: providing fables, observations and interpretations for the city continuously, recording people and things here, and writing the subtle life situation and spiritual space of Hong Kong people.

It was Hong Kong literature that first "literated" Hong Kong-

Without Liu Yichang’s novels, there would be no lingering and bizarre streets in Wong Kar-wai’s films.

Without the creation of Jin Yong and Liang Yusheng, there would be no people and rivers and lakes of the Eastern Martial Arts;

Without the wonderful pen of Zhang Ailing and Huang Biyun, there would be no subtle and touching "Hong Kong style" love …

Today, let’s review the representative writers and works of Hong Kong literature in the past century.

1920s

Lu Xun’s visit to Hong Kong and Iron Horse

The earliest Hong Kong literature

In 1921, the literary magazine Shuangsheng was founded. The editors of the magazine, Huang Kunlun and Huang Tianshi, were both young writers of the new trend of thought. They wrote Hong Kong stories in semi-vernacular, which is called "free-footed", and expressed their ideas of anti-feudalism, personality liberation and free love, which constituted the first glimmer of Hong Kong’s early new literature.

Six years later, with the staged victory of the Northern Expedition, the old forces and warlords were overthrown, the new literature movement in the Mainland flourished, and works of various genres were gradually imported into Hong Kong.

In February, 1927, Lu Xun was invited from Guangzhou to Hongkong to give two speeches, entitled Silent China and Old Tune Finished.

In his speech, Lu Xun said: The old culture made people tell old sayings in difficult ancient Chinese, and most people couldn’t understand them, which was equivalent to silence. He advocated that modern people should speak their own modern words and turn silent China into a talking China.

Lu Xun’s speech aroused the panic of the Hong Kong authorities and feudal old-school literati. They first "sent people to ask for admission tickets and collected them so that others could not listen;" Later, the speech was not allowed to be published in the newspaper. As a result of negotiations, it was cut and changed a lot. "

However, young people in Hong Kong still responded enthusiastically to Lu Xun’s speech.

Hong Kong in Colonial Period

After that, many new literary groups and publications appeared one after another, which is proof. Among them, the most important is the pure literary publication Iron Horse, which was founded in 1929, and it marked the official appearance of Hong Kong’s new literature.

"Iron Horse" wrote:

"We put our machine guns and cannons to deal with the fists of antiques, and beat him out of the water. They are the laggards of dynasties, the demons of the world, and the Uber of literature. If we keep them, we will never turn over. Young literary friends, this is a job that has passed, but it is a brand-new job in Hong Kong. This requires our joint efforts. New literary warriors, this is the first cry of Hong Kong culture! "

In Iron Horse magazine, 18-year-old Lu Lun published the novel Fireside. This novel, wrote down the poverty of Hong Kong literature youth-

Puya Street is a rundown street in Hong Kong. There are no footprints of gentlemen and ladies, no music in the square, and no municipal surveyors and engineers have been here. On winter nights, people who live here feel that everything is cold psychologically. "The cold rules together, because the street is narrow, the wind blows especially hard, and the door that is not tightly closed and the six buttons that are not tightly assembled make a slight earthquake. Like this huge house, it can’t resist the cold wind, and its teeth are chattering."

In this poor street, there lived two young Hong Kong writers, T and K, writing in the cold. They usually write articles for newspapers and rely on the payment settled at the end of the month to make a living. It is very sad to live by pen and ink. There are many newspapers in Hong Kong, but most of the publishing sites are occupied by a few people. Those poor people who can’t curry favor with the editor-in-chief are reduced to a dangerous level, and sometimes they can’t even eat bread. T "has lived here for half a year, and not a day goes by without him struggling in pain." At first, he lived in a better place. Later, one or two more reliable newspapers were unexpectedly closed, and he moved to this dirty Puya Street at the suggestion of his friend K, just next door to K. "

Lv Lun, the first generation of new literature writers in Hong Kong

Because of the repeated delay in the payment of the manuscript, T’s rent can no longer be paid, his wife has been humiliated by the landlord, and the rice has bottomed out. The fire wine, foreign candles, ink and even manuscript paper have all gone, and there is nothing to sell at home. He can only stay up late to write and expect to get this month’s statement the next day. The next day they went to ask for the manuscript fee, but the newspaper office still asked him to "spend a few days." In the last part of the novel, I turned to write A, the literary editor of three newspapers in Bendu. The manuscript written by the author who worked so hard to stay up late was not a serious matter to him at all. Last year’s manuscript, he delayed reading it by the fire until now. When his wife came over to make out, he threw the manuscript aside and fell into the stove. "When the stove lit up, they felt a burst of warmth and their arms hugged each other more tightly."

-Zhao Xifang’s "The First Shout of Hong Kong Literature"

The style of the novel is gloomy, and it is impossible to write such words without deep experience of the life of cooking words to cure hunger in Hong Kong. Poor writers pointed the contradiction at newspaper editors, but in fact, the root of Hong Kong’s underdeveloped new culture at that time was its social nature.

After his visit to Hong Kong, Lu Xun returned to the mainland and wrote about the gloomy social outlook of colonial Hong Kong-

"Although Hong Kong is only an island, it vividly depicts the present and future of many places in China: several foreign masters in the central government, under whom are a number of" higher Chinese "who praise virtue and a group of enslaved compatriots. In addition, they are all "natives" who suffer silently. They can die in the foreign market and escape into the mountains … "

-Lu Xun’s "Just Set" and "Let’s Talk about Hong Kong"

The British occupation of Hong Kong was originally for the sake of trade, and it was not intended to encourage Hong Kong to develop its own culture. What was more concerned was how to spread British culture and values here.

In such a social system, the way out for pure Chinese literature is hard to find. At that time, the young literary people who founded Iron Horse had the naive idea that if the first issue was printed, the second issue could be published by relying on the sales income, so as to maintain the magazine. However, The Iron Horse didn’t sell, and it died in the first issue.

Of course, the economy is one of the reasons for the suspension of the publication of Iron Horse, but as Lu Lun said: "The main reason is the lack of social environment that allows them to survive."

In the 1930s, the activities of Hong Kong literary youth did not stop. Between 1931 and 1937, other publications such as Riptide, Spring Thunder, Today’s Poetry and New Life came out.

Although the literary youth in Hong Kong during this period were still learning Yu Dafu’s style, imitating Shen Congwen’s novel techniques and experiencing Xu Zhimo’s poetic expression, most of them borrowed stones from other mountains to express their dissatisfaction with the reality of colonial society and their personal feelings, thus slowly forging a path.

The Iron Horse was founded by the Island Society in September, 1929.

1930s-1940s

Xiao Hong, Zhang Ailing, Dai Wangshu

Literature and War

After 1937, due to the outbreak of War of Resistance against Japanese Aggression, many mainland writers came to Hong Kong to engage in cultural work, which made Hong Kong a small "cultural center" for a time.

Many important writers in the history of modern literature in China, such as Ba Jin, Mao Dun, Xu Dishan, Dai Wangshu and Xiao Hong, all wrote in Hongkong.

In 1938, Dai Wangshu presided over Constellation, a supplement to Sing Tao Daily, which developed this platform into a cultural starry sky of Hong Kong’s new literature and also became a literary lighthouse in China during the Anti-Japanese War. Mao Dun, Shen Congwen, Yu Dafu, Bian Zhilin, Guo Moruo, Ai Qing, Xiao Jun, Xiao Hong, Xu Chi and others all published their works here, as Dai Wangshu himself said: "Wen The writers in exile in Hong Kong are also constantly contributing manuscripts. We can actually say that there is no well-known writer who has not written an article in Constellation. "

On December 8, 1941, after the Pearl Harbor incident, the Japanese army quickly invaded Hong Kong. On this day, the University of Hong Kong just held the final exam. When the female student Sheng Jiuli and her classmates were preparing for the exam, they heard that the war broke out, and they were suddenly liberated.

At the same time, a pair of men and women in troubled times, Fan Liuyuan and Bai Liusu, were talking about love. At the stage of stalemate, Japanese artillery shells came, and they suddenly knew the necessity of falling in love with the whole city in troubled times.

This is of course the plot in Zhang Ailing’s novels.

Zhang Ailing’s School Record in Hong Kong University

Zhang Ailing went to Hong Kong University to study in 1939, and her experience in 1941 became a lingering historical mark in her creation. And when historical events collide with the love described by Zhang Ailing, the meaning of the story appears-

It was December 7, 1941, December 8, and the gun rang. Between one shot and another, the silver fog in the winter morning gradually dispersed. On the top of the mountain and in the ravine, the residents of the whole island looked at the sea and said, "Let’s fight, let’s fight." No one can believe it, but after all, it is a war.

Tassel stayed alone in Babington Road, and she didn’t know anything. When Ali got the news from her neighbors, she woke her up hastily, and the outside had entered the stage of fierce fighting. There is a science experiment hall near Babington Road. Anti-aircraft guns are mounted on the roof, and stray bullets keep flying over, screaming, "Cheep, yo, er, er, er …" and then "bang" and falling to the ground. The sound of "creaking, uh, uh, uh …" tore the air and tore up the nerves.

The pale blue sky was torn into strips and fluttered in the cold wind. There are countless cut nerve tips floating in the wind at the same time.

……

Tassel also thought of Liuyuan, wondering if his ship had sailed out of the port and been sunk. But when she thinks of him, she feels a little slim, like a lifetime ago. Now this paragraph has nothing to do with her past, like a radio song, halfway through, suddenly affected by the bad weather, it crackled and exploded, and when it was over, the song still had to be sung, and I was afraid it was over, and the song had been sung, so there was no need to listen.

1950s

Jin Yong and Martial Arts

Adult Fairy Tales and the Roots of China Culture

From many books about Hong Kong’s anecdotes, it can be seen that since Hong Kong opened its port in 1842, its public security did not show signs of improvement until the middle of the 20th century, so there has always been an atmosphere of martial arts among the people. In 1953, Wu Gongyi, the head of Tai Ji Chuan, competed with Master Chen Kefu, the master of Baihequan, which became an important cultural event among the people.

Inspired, Luo Fu, editor-in-chief of New Evening News, tried to create a serial column of martial arts novels in the supplement, inviting Chen Wentong and Cha Liangyong, who can write and edit, to appear. Chen Wentong wrote the first martial arts novel "Long Hudou Jinghua" under the pseudonym Liang Yusheng, and Cha Liangyong wrote the first martial arts novel "Shu Jian An Qiu Lu" under the pseudonym Jin Yong.

It was an instant hit, and the sales of New Evening News doubled, which made Liang Yusheng and Jin Yong famous, thus forming the beginning of folk political literature based on the left wing in Hong Kong.

Jin Yong and Liang Yusheng

Jin Yong came to Hong Kong in 1947 and worked as a translator in Ta Kung Pao. At first, Jin Yong didn’t like Hong Kong. He once described his feelings when he first arrived in Hong Kong: "It’s a bit like being in a rural place." But it soon changed: "But generally Hong Kong people are frank, confident and reliable, and I like them soon."

In 1950s, there were many migrants in Hong Kong. They were not all intellectuals, but more working class. However, they all had the same characteristic, that is, their desire for martial arts-themed books.

In their eyes, compared with the Central Plains cultural soil in the Mainland, Hong Kong is undoubtedly barren. In addition, Hong Kong was ruled by the British, which prompted the emergence and outbreak of national sentiment in their hearts, and they all had a strong interest in books, movies and music of China’s traditional culture-these "spiritual food" could help strangers in a foreign land dispel their complex feelings of being in a colony.

Jin Yong’s novels can fully embody this function. They are not only consumer goods, but also have the elements of "resistance" of martial arts. For the Hong Kong public at that time, they are a kind of reading materials with the function of filling and repairing.

At that time, readers not only had a soft spot for martial arts novels, but also had deep feelings for the China culture involved.

The cultural elements of China in Jin Yong’s novels can be said to be very diversified. Poetry, religion, martial arts, five elements, Taoism, calligraphy and painting are all important tools to convey China culture, and they are also important elements of traditional China martial arts novels.

Huang Yaoshi, the East Evil in The Legend of the Condor Heroes, is a figure who knows the essence of China culture. He is proficient in piano, chess, calligraphy and painting, and in medicine, and he knows everything, not to mention his unique skills in literature and martial arts. Novels often borrow his daughter Huang Rong to prove his father’s superiority. For example, when Guo Jing and Huang Rong first arrived in Lujiazhuang, Huang Rong expressed his paintings and inscriptions on the wall of the study, and made a clear statement-

Huang Rong saw that the study was full of beautiful things in eyes, full of poems and classics, and there were many bronze and jade articles on the table. It seemed to be full of antiques, and there was an ink painting on the wall, which showed a middle-aged scholar standing in the atrium on a moonlit night, with his hand on the hilt, looking up at the sky and feeling lonely. There is a word in the upper left corner:

"Last night, I couldn’t stop singing. It’s already midnight. Get up and walk around the steps alone. People are quiet, and the moon is bright outside the curtain.

White head is fame. The old mountain pine and bamboo are old, which hinders the return journey. I want to pay my heart to Yao Zheng, but I have few bosom friends. Who will listen to the broken string? "

……

When the landlord of the land saw Huang Rong’s close examination of the picture, he asked, "Brother, how about this picture? Please read the title." Huang Rong said, "Don’t dare to talk nonsense, Master Zhuang." Lu Zhuang said, "Brother, just say it’s okay."

Huang Rong said, "The picture of Master Zhuang shows Yue Wumu’s feeling of being unable to stretch his ambition and being at a loss when he wrote this poem" Small Mountains ". It’s just that Yue Wumu’s ambition is for the country and the people, and the phrase "Whitehead is fame" may be the meaning of avoiding suspicion and raising bad luck. At that time, the monarch and his subjects in the DPRK all wanted to make peace with the Jin people, but Yue Fei insisted, but unfortunately no one listened to him. With few bosom friends, who will listen to the broken string?’ These two sentences are said to mean that in this case, it is a helpless mood, but it is not openly against the court. When the master of Zhuang painted and wrote, he seemed to be angry and full of twists and turns. Although his brushwork was extremely vigorous, he was sharp-edged, as if he wanted to fight a life-and-death battle with his great enemy, for fear that it was slightly different from Yue Wumu’s original intention when he was worried about his country and hurt his country. Xiao Ke once heard people say that calligraphy and painting, if it is too powerful and lacks the meaning of roundness, seems to have not yet reached a very high level. "

After listening to these words, Lord Lu Zhuang sighed, looked mournful and remained silent for a long time.

-Jin Yong’s Legend of the Condor Heroes

58th Edition Poster of Legend of the Condor Heroes

In the 1950s, the living conditions in Hong Kong were low, and most people in Hong Kong lived in extreme poverty. Only a few British people in Hong Kong hold high positions and lead a luxurious life. Ordinary people have no affection for the British government in Hong Kong, and at the same time they are powerless to resist, so they care more about the "roots of China culture", which is also the reason why the new martial arts novels in Hong Kong spread rapidly in the 1950s. For the people, martial arts novels are "adult fairy tales", which can relieve the pressure brought by real life and soothe their homesickness.

In the 1980s, Jin Yong’s novels were introduced to the mainland, and readers completed a new round and a wider range of cultural root-seeking through martial arts stories. However, that is another story.

1960s

Liu Yichang, Modernism.

Wong Kar-wai’s literature teacher

If Jin Yong is a master in the field of popular literature in Hong Kong, there is another master in the field of serious literature in Hong Kong, that is, Liu Yichang.

Liu Yichang’s name is unknown to many people. The word "chàng" is very rare. If you don’t look it up in the dictionary, few people will immediately pronounce it correctly.

Writer Liu Yichang

But in the Mood for Love directed by Wong Kar-wai is well known. Wong Kar-wai once said that he drew inspiration from Liu Yichang’s long stream-of-consciousness novel "Dui Dao" when he made this nostalgic film of absolute beauty. It can be said that Liu Yichang is a literature teacher in Wong Kar-wai.

In February, 1960, Liu Yichang, a young writer, took over the supplement of Repulse Bay of Hong Kong Times, and immediately set out to create a "modernist school" of Hong Kong literature. He published a large number of works by Woolf and Joyce, and actively translated and introduced the theory of stream of consciousness.

At the same time, in order to meet the needs of life, he has to write a large number of popular novels to meet the needs of the market, often writing more than ten newspaper serial novels a day, as he said: "To accommodate readers and write novels they like to read." Therefore, during the day, he writes works that entertain others, and at night, he writes his favorite novels when he is free. His serious literary works "The Drunken" and "Dui Dao" were created in this way.

In 1963, Liu Yichang published the novel The Drunken with obvious autobiographical color. The novel boldly used the artistic techniques of western modernist novels such as stream of consciousness and symbolism to describe the wandering, struggling and sinking of the "I" of the "Drunken" in the two postures of sobriety and drunkenness, so as to depict the living dilemma and sensitive and complicated inner world of the urban people (more accurately, urban intellectuals) in Hong Kong. This work is also known as "China’s first novel of stream of consciousness".

Stills of In the Mood for Love

In 1972, Dui Dao was published. In fact, there is not much story in the novel. The two protagonists, Chun Yubai and Yaxing, don’t know each other and have never talked. The novel only describes the two lives they lead on Nathan Road, and the only overlap is the inverted state formed by Chun Yubai’s memory of the past and Yaxing’s imagination of the future, which is a relatively novel structural technique in Chinese novels-

one

When the No.102 bus entered the Cross-Harbour Tunnel, Chun Yubai remembered something more than twenty years ago.

Twenty years ago, Hong Kong had a population of just over 800,000. Now the population of Hong Kong is close to 4 million. Many desolate places have become lively resettlement areas. Many old buildings have become skyscrapers.

He can’t forget flying from Shanghai to Hong Kong more than twenty years ago. When he got on the plane, he was wearing a thick fur robe. When he got off the plane, he saw many Hong Kong people wearing only a white shirt. This place is not very cold in winter. Even on Christmas Eve, people still eat ice cream at the table.

Chun Yubai came to Hong Kong from the north on Christmas Eve. The war to the north of the Yangtze River is getting more and more fierce. The frenzy of golden coupons made the people unable to breathe. Shanghai is under the pressure of war and in turmoil. Many people have come to the south. Some settled in Guangzhou, while others chose Hong Kong.

Chun Yubai has never been to Hong Kong, but intends to move to Hong Kong. There is only one reason to do this: the Hong Kong dollar is a stable currency. When Chun Yubai came to Hong Kong from Shanghai, one dollar could be exchanged for six Hong Kong dollars. Now, you can only change it to five six two five.

two

Most of the wooden ladders in old buildings have been eaten by termites, and when you step on them, there will be a squeaking sound. These wooden ladders should have been repaired or replaced long ago. No repair, no replacement, because the owner has sold this old building before the war to the real estate company that is expanding in major events at a high price. This is what menstruation told Yaxing.

Menstruation of Yaxing has lived on the third floor of this old building for more than twenty years. Yaxing and menstruation have a very good relationship, and they always walk around when they have nothing to do. Now, when she walked down the wooden ladder, she had a Sydney in her hand. Menstruation gave her this Sydney. Yaxing walked out of the old building, and it was the time when Chun Yubai took the bus and entered the cross-harbour tunnel.

Turn into the street and smell an unpleasant smell. There is a public toilet here, so that every passer-by walking in this street must cover his nostrils with a handkerchief or palm. Yaxing doesn’t like this crosswalk because it has public toilets. Every time I pass by the public toilet, I always miss this:

"In the future, if you get married and find a house, you must have a good environment. There must be no public toilets nearby."

-Liu Yichang’s "Down"

French poster of In the Mood for Love

Without Liu Yichang, it is hard to imagine what Wong Kar-wai’s 2046 and In the Mood for Love would be like. In the Mood for Love, in a sense, is a film interpretation of Dui Dao. When filming, Tony Leung Chiu Wai never got into the atmosphere of the 1960s. In order to capture the feelings of the times, Wong Kar-wai suggested that Tony Leung Chiu Wai imagine Liu Yichang in the 1960s.

Liu Yichang’s cultural demeanor at that time was the cultural meaning that Wong Kar-wai wanted to express. Liu Yichang foresees many possibilities for the interweaving between Hong Kong’s social culture and literature, and his works are also worth reading and rereading.

1970s

Xixi’s My City

Cities are alive, how can they remain the same?

In 1975, writer Xixi serialized the first important novel My City in Hong Kong Express. Now, it has already become a classic of Hong Kong literature.

Xixi was born in Shanghai in 1938. In 1950, he came to Hong Kong from Shanghai with his family to attend junior high school. The martial arts films in the cinema and Cantonese in the classroom opened a new world for her.

After graduation, she became a primary school teacher. "At that time, there were too many teachers and too few students. I retired in my thirties. At that time, I will either transfer to the post office or the zoo to work or retire, and I will retire. "

Since her retirement, she has been specializing in literary creation. According to herself, her pen name is hieroglyphics. "Xixi" is a girl in a skirt standing in a square grid with her feet on the ground. "Xixi" means jumping off a plane, which is a game she liked to play when she was a child.

Writer Xixi

My City, a 160,000-word novel, is Xixi’s masterpiece. Scholar Wang Dewei once commented that "Xixi made a naming ceremony for Hong Kong’s subjectivity in the form of literature."

Ma Shifang, a Taiwan, China writer and music radio program host, attended the college entrance examination and saw the cover of My City in the bookstore. He opened it curiously and was fascinated when he saw the beginning.

"I nodded my head to them. Yes, what can I say except nodding my head to them?"

-Upside-down, collage and remodeling. In Ma Shifang’s impression, this novel is neither bitter nor shallow. Although it was written in the 1970s, the freshness of the language is still like making very powerful pop music, and it is not out of date.

In Xixi’s view, "what I want to write is my specific and subtle thoughts and feelings at the moment, and I am very concerned about how to write." Hong Kong has been changing, the city is alive, can it remain unchanged, and can it be written as an iron plate? "

The narrator of My City is the character Aguo in the novel. When it was published in the newspaper, the author signed it with Aguo. Xixi once explained, "Aguo is actually my brother, because he graduated from middle school to find something to do at that time and ended up in a telephone company. He told me the stories he heard every day. I wrote this novel in the kitchen. "

In the book, she borrows the vision and language of young people represented by her younger brother Aguo to describe Hong Kong’s parks, Vietnamese refugee boats, water shortages and floods, social security and other issues at that time, as well as her personal life as a telephone line worker Aguo. According to the book, when Aguo received a phone call and learned that he was hired, he was extremely happy-

The telephone on the writing desk is camel-colored.

-I’m Aguo.

Who are you? Perhaps, you are Mr. Engineering Department, perhaps, you are Mr. Construction Department. I have no idea who you are. I told you I’m Aguo. Can you tell me who you are, too?

── A mother Xiu Xiu.

── You Mei Afa

What kind of relatives are there in your family? The picture of the little girl on the desk must be your daughter. She likes flying kites. I like flying kites. I have a tofu kite, but there is no place to put it.

-Just came out of school.

-It’s this year’s examination.

You’ve taken many exams, right? Do you also like geography and history when you are studying? Studying geography is interesting, and you can know that there is so much space. If you read history, you will know that time has no beginning or end. So much space, so no head and no tail time, but I will meet with you, only across a table, you say it’s a coincidence. But I don’t know who you are, and I don’t know if I can ask your name.

-was born in this city.

── Never left.

……

Yes, the weather is fine today. Later, you do what you like and I’ll do what I like.

The man sitting opposite the writing desk scribbled a string of words on a piece of paper and gave it to me.

-Young people, do it well.

He said.

-That goes without saying.

I said. I thanked him and came out.

Oh, the old sun shines on my head, the old sun in the eighteenth, fifteenth, twenty-seventh and thirty-ninth centuries. From tomorrow on, I can treat myself to dinner, I can treat my mother Xiu Xiu to dinner, and I can treat my sister Afa to dinner. I am very happy. I have been happy until the next morning.

-Xixi "My City"

My City/Xixi/Suye Publishing House/1979

The structure and text layout of My City are not solid, and it is not to bring readers to a definite ending. Xixi gives readers a free space to interpret, and everyone can have different interpretations.

Some people think that "My City" deliberately writes this novel in a childlike and almost childlike style. The text is relaxed and full of sunshine, but it also implies a satire on Hong Kong in the 1980s. Some critics also said that when reading the book My City, we might as well watch it from the perspective of the Riverside Scene at Qingming Festival, because the structure of My City is essentially the same as this picture.

Xixi herself said that she wrote My City with fantasy, which is different from magical realism in Latin America. Some people say it can be called fantasy realism, while Xixi says it may be called fairy tale realism. No matter what doctrine, it is always realistic.

1980s

Huang Biyun’s Love in the Prosperous Age

Dissect people’s hearts and look directly at life.

In the 1980s, Huang Biyun’s description of the living conditions of contemporary Hong Kong people showed a new trend.

Huang Biyun is a maverick writer. She has a master’s degree in criminology, worked as a journalist, an assistant to a member of parliament, opened a clothing store and studied modern dance. In her early years, she left the law firm as an intern in London and rented a small apartment in Spain. While writing, she studied flamenco diligently.

After returning to Hong Kong, Huang Biyun began to work in a busy law firm. However, her creation continued, and her life, like the city of Hong Kong, continued to fly like a dancer.

Writer and critic Nan Fangshuo commented on Huang Biyun: "She is different in narrative style and thought of her works. She hides redemption in decadence and is gentle in violence …"

Writer Yang Zhao said: "To read Huang Biyun’s novels, we must first understand what addiction is;" Reading Huang Biyun’s novels, let’s explore the significance of this felony of despair in our lives … "

Huang Biyun, like Zhang Ailing, is good at dissecting people’s hearts and looking straight at bloody life. Her "Love in a Prosperous Age" can be said to have won the true biography of Zhang Ailing.

Writer Huang Biyun

This novel, published in 1986, reveals a disease of the times and a disease of the city, and thoroughly exposes the alienated nature of modern marriage and the hopeless absurd relationship of modern people-respect each other as guests, but have no true feelings; Sleeping together, but having sex without love; Under the prosperous times, people are vain, helpless and lonely.

One of the core tasks of literature is to observe the world and people’s hearts, express the various forms of life, tell ever-changing stories, reveal subtle emotions and reveal the relationship between people and the surrounding world. Love in a Prosperous Age has such artistic characteristics, and it is a typical work in Hong Kong contemporary novels to express the relationship between the people of the city.

Cheng Shujing, the woman in the story, was originally a student of Fang Guochu. Later, they developed a teacher-student relationship and got married by lightning.

This marriage, which lacked true love, soon ended in divorce. The plot of the story is very simple, but the connotation is extremely profound, showing the chaos of war and the disillusionment of personal life value under the peaceful and prosperous times.

In the works, there are many scenes with expressive force behind the paper. For example, the scene where the teacher Fang Guochu proposed to the woman was at the scene of a car accident, and the two were touched by the scene-

Both of them had nothing to say in the car, and Fang Guochu reached out to hold Shujing’s hand. The book is quiet and struggling, and the country is lighter and more entangled. Book static then deigned, don’t look at him, but all feel his presence.

The book looked at the scenery outside the window quietly, a little confused. He loved her, but he was not influenced by her. He loves her, and he only regards her as a woman in a bed; He doesn’t love her, but he looks for her …

Shu Jing is just weak. At this time, the car suddenly braked, and the van in front collided with a taxi. Somehow, the tail of the van turned upside down, and it was quiet towards the book, and the front glass was broken. The driver is a young man in his twenties, lying on the steering wheel, asleep, with a few drops of blood sticking to his hair, and his color is very theatrical.

Fang Guochu pressed the number and said, "Shit, I don’t know how long it will take." Book static can’t help scratching at him. The young man struggled and fell down again, revealing the hand of the bones, which were extremely clean in the sun. The cars jammed were quiet, the police didn’t come, and everyone was calm, waiting around the bones, waiting for what.

Fang Guochu held the book tightly, and the book leaned against the window, which was cold and unpopular. She couldn’t help but breathe and let the window fog up to prove that she was alive. After a while, Fang Guochu said, "The Fire Department said that all ambulance personnel would arrive at the scene of the accident within 12 minutes, which is simply the biggest lie in the world."

Book static also can’t help looking at the bones. She thinks that nothing will go away before she has a bright nightmare, so don’t allow you to be arrogant. Fang Guochu suddenly said, "No, that’s just the third biggest lie."

How short life is, how rare it is to meet each other, how much you think about it, and how much you are obsessed with it. Before this bone, it was all a lie.

Fang Guochu said: "The second biggest lie is: I love you. I only love you. "

It doesn’t matter whether it’s empty talk or not. What’s not a dream in the mirror? Before the bones, perhaps the most stubborn person will be willing to be deceived.

Fang Guochu turned around, leaned against the steering wheel with one hand and said with a smile, "Do you want to hear the biggest lie in the world?"

Shu Jing always looked at the hand of Bai Gusen, and she didn’t care about anything when she put it on the steering wheel. Fang Guochu said, "Will you marry me?"

Shu Jing gently held his hand and felt blood and flesh-nothing more than flesh and blood. Maybe that’s it. Marriage. What does it matter? This body is nothing more than flesh and blood. She said, "Good."

She never turned to see him.

-Huang Biyun’s "Prosperous Love"

In this way, they got married. On the night of the bridal chamber, Fang Guochu was drunk, and Shu Jing said with a wry smile, "Marx said that marriage is institutionalized prostitution, so he was right." She found that she had done something wrong and "married an old man".

"falling sky" stills

Chu Yuan was a promising man who held high the ideal banner, but he became secular and lazy after marriage. "He got his doctorate, got the teaching staff, and the three-year probation period for doing research has passed … even got married." He became bored, and the only thing he could do was to get fat. He drank a big beer after class and completely ignored his wife’s feelings.

This kind of marriage is a portrayal of countless realistic husband-wife relationships in Hong Kong at that time-the same alienation and the same emptiness, but it seems that only Huang Biyun carved it so thoroughly and so thrilling.

In the history of Hong Kong literature, it seems that only Zhang Ailing has such talent and pen power. In fact, this work, like the modern version of Love in a Fallen City, has formed a wonderful echo.

1990s

Dong Qizhang’s "Heavenly Creations, Realistic"

Literature is characterized by a word "slow"

Dong Qizhang is perhaps one of the most representative writers of pure literature in Hong Kong today.

In 1994, 27-year-old Dong Qizhang wrote the novella "Jenny Android" and the short story "Young Shennong". At that time, computers were not popular. He spent more than a month copying these two novels by himself and his friends, and sent them to Taiwan, China to participate in the "Joint Literary Novel Newcomer Award". In the anonymous judging, after several arguments, the judges selected Jenny Android as the first prize of novella and Young Shennong as the first prize of short story. They all agree that "Jenny Android" is a rare "female writing" and "negative writing". Yang Zhao, one of the judges, believes that although the author is from Hong Kong, the language level of the author of "Jenny Android" is obviously higher than that of "Young Shennong".

When the meeting ended, the organizer announced that the authors of these two novels were both Dong Qizhang, and the judges were very embarrassed. They had never heard of Dong Qizhang, not only that, but they didn’t expect that the authors were men.

Dong Qizhang was born in Hong Kong in 1967. He started writing in 1992 and worked as a middle school teacher. His life experience is not complicated. He studied all the way to the Bachelor of Arts and Master of Arts in Hong Kong University. It likes Proust, Calvino, Borges and other modern writers with dazzling knowledge, and gradually established its own literary view and writing style in such extensive reading, that is, literature should not only express feelings and aspirations, but also speak knowledge.

Dong Qizhang’s most important work is his trilogy of natural history. Among them, the first one, Heavenly Creations, Lifelike, has 500,000 words, and the trilogy has more than 1.6 million words in total.

Writer Dong Qizhang

This kind of personal epic novel, its writing perseverance itself is admirable, especially in Hong Kong, a city that pays attention to time and efficiency. A novel with nearly 500 pages is a miracle. Wang Dewei once commented that "I am willing to devote my life or half my life to the handicraft industry of literature and writing. We should pay tribute to Dong Qizhang and other writers like him. "

However, Dong Qizhang believes that the characteristic of literature is just a "slow" word. Everything is fast in the internet age, and it comes and goes quickly. "But literature should be written slowly, read slowly, feel and think slowly."

The trilogy of natural history is the product of Dong Qizhang’s precise planning and slow progress. From the beginning of his writing, he consciously built a common virtual world through many works, and they used the same names-V City, Dong Fu, Vivid and Xiaodong, which made people think of Faulkner’s "Yorknapatafa lineage" and the creative concept put forward in Canglang Poetry: the entry must be correct and the conception must be high.

This novel is first of all a personal history of Dong Qizhang or "I". In reality, Dong Qizhang’s business card is printed with "Dong Fuji Writing Workshop", which corresponds to the "Dong Fuji" mechanical parts manufacturing workshop once run by Dong Qizhang’s grandfather and father. He inherited the factory with literature. In this novel, his basic technique is to create the images that make up the story just like making parts, and then these image group weaves a complete symbolic system.

It is through one "thing" after another that Dong Qizhang described the history of Hong Kong for more than 100 years from the late Qing Dynasty to the early Republic of China to the reunification, told what happened in Hong Kong for more than 100 years, and described the stories of three generations of his family. Among them, there is not only a great history, but also a history of the relationship between objects and people.

For example, one of the items is an old sewing machine. For many families in Hong Kong, the old sewing machine is worth remembering, because when Hong Kong’s economy was about to take off, many women were driving such an old sewing machine at home to help with the work of material processing, earning some extra money and supplementing their families.

This book has a very subtle description of the old sewing machine, which is said to be more violent than all heavy machines. It poked the dolls needle by needle and pierced them to connect them-

Vivid, I must tell you honestly, your image sprouted earlier than when I met Ruzhen. This idea was born in my childhood when I helped domestic workers. No, it’s not just an idea, it’s a concrete prototype of you.

It was a time when my mother picked up dolls to make artifacts. At first, it was just sewing women’s shirts and skirts as small as an adult’s palm, including mini skirts, student skirts, tennis skirts, denim skirts and sexy evening dresses with suspenders, as well as a swimsuit with lace on the hips and a puzzling bikini.

When I was sitting next to the locomotive-like clothes cart and cutting threads for these small clothes one by one, I seemed to feel the hint of these intimate clothes. At a young age, I don’t think of the clothes popular with young girls on the street.

They just remind me of a person’s closet. That wardrobe is full of clothes of that color, line and pattern. Sometimes they are attached to a body, and sometimes they are removed.

Later, we didn’t just sew dresses, but my mother brought back two bags of light pink things, one of which was filled with a small soft pillow-shaped flat baby face. The cold blond hair on the head and face, beaded eyes, ears protruding on both sides, a soft button nose and a curved mouth embroidered with red lines have also been made by other workers. The other bag contains cloth pieces of different sizes and shapes, which are stitched together to form the hands, feet and torso.

In fact, the process is not difficult, as long as those limb pieces are stitched on top of each other, with the reverse side outside and the front side inside, and connected into a flat human figure, leaving an opening at the lower part of the body, pulling out the material that should have been the front side from the opening, like turning over gloves, and then stuffing cotton with bamboo chopsticks from the opening until it is filled into a three-dimensional pink limb. Then sew up the head, then sew up the hole in the lower body, and finally put on a pre-made blouse and skirt, and you’re done.

Of course, the lathe work is all done by my mother alone. I am responsible for stuffing cotton from my lower body and the final dressing steps.

Sometimes the cotton is blocked at the joint, so I poke it into the hole with chopsticks, and I don’t feel rude. I’m afraid to see the sewing needle of the clothes cart plunge into those soft humanoid materials, as if the meridians all over my body were swollen and painful at the same time. But I can’t help but watch the process, especially the final process. That’s to be stitched by hand. The needle tip goes into one side of the breach, and the eye of the needle pulls the thread in, stirring up the flesh on the other side, piercing, pulling it out, and going back to the other side, like learning to wear a shoe belt when I was a child, until the whole lower body is tightly closed. A few years later, I witnessed the traces left by such a procedure on my aunt He Yayu’s belly.

-Dong Qizhang’s "Heavenly Creations, Realistic"

Heavenly Creations, Lifelike/Dong Qizhang/Shanghai People’s Publishing House/March 2010

This novel is full of different objects, which are written as metaphors and symbols, representing the changes of the whole history.

What Dong Qizhang wants to emphasize is that all the characters in the novels are actually "things" because they are named after Song Yingxing in the Ming Dynasty. "Heavenly Creations" is just a process of artistic creation, and there is no distance between natural creations and man-made ones.

Liang Wendao recommended Heavenly Creations: "It’s a novelist’s novel. It almost wants to exhaust all the novel skills you can imagine. "

2000s—2020s

Ma Jiahui’s "Dragon Head and Phoenix Tail"

Just do what you are happy about.

Ma Jiahui was born in 1963, and his father was the editor-in-chief of a newspaper. He bathed in cultural atmosphere since childhood, but he did not have a typical literati character, but he was somewhat Jianghu.

Ma Jiahui’s growing years are just catching up with the rapid development of Hong Kong in the 1970s. Wan Chai, where he lived, was also one of the most chaotic, street-like and dynamic places in Hong Kong at that time. Sometimes, he sits in a food stall and eats breakfast, and behind him is the underworld who fights and kills.

At the age of 20, Ma Jiahui had already been admitted to a university in Hong Kong, but because he was fascinated by Li Ao, he went to Taiwan Province to study while doing Li Ao studies.

When he was a sophomore or a junior in college, his book "Destroy Li Ao or Be Destroyed by Li Ao" became a best seller in Taiwan Province. Even Li Ao himself said to him, "Jiahui, Hu Shi said that I knew Hu Shi better than Hu Shi. I said today that you know Li Ao better than Li Ao. "

At the age of 30, Ma Jiahui got a doctorate from the University of Wisconsin, but he didn’t have the patience to be a scholar. He returned to Hong Kong and became a vice president of Ming Pao, making a big turn before he came to teach at the university.

Writer Ma Jiahui

Ma Jiahui writes a column for a newspaper, goes to a TV station to do a program and be a guest. It seems that he can pick up any martial arts. But when he was almost 50 years old, he suddenly sat down and wanted to write a novel, not one, but a "Hong Kong trilogy".

"Writing novels is an eternal challenge for a person who loves literature and writing." Ma Jiahui said, "Maybe I’m pessimistic. I feel that once I’m over 50, what I see is different from what I saw before. Before I was fifty, I looked ahead and thought I had a lot to do. After 50, my eyes look back, as if I feel that there is not much time ahead. "

The first part of the "trilogy" is called "Leading Phoenix Tail", which was published in 2016 and wrote about Hong Kong during the Japanese occupation; The second book, Yuanyang 674, was written in Hong Kong in the 1950s and 1960s and published in 2020. The third part, which Ma Jiahui wants to write, is about Hong Kong in the 1970s and 1980s, until the return of Hong Kong.

Feng Wei, the Dragon Head, is an ambiguous story between Lu Nancai, a triad boss who fled from Guangzhou to Hong Kong, and Zhang Dichen, a British policeman.

In order to avoid chaos, Lu Beicai fled to Hong Kong from his hometown of Heshi Town, Maoming City, Guangdong Province. His name changed from north to south, and he settled in Wan Chai as a rickshaw puller, shuttling between bars, police stations, casinos and prostitutes’ villages in Wan Chai and Central Sheung Wan.

Behind the history of the rise of gangsters, there are the colonial regime in the 1930 s and 1940 s, the Japanese invasion of China and the fall of Hong Kong. The novel also involves Chen Jitang, Du Yuesheng, Wang Jingwei and other historical figures.

In such troubled times, in the complicated bottom society, Ma Jiahui wanted to write about the homosexual love between Chinese and foreigners, and used gender to intensify the conflict and struggle between race and power in the story.

Ma Jiahui once said, "In the sixties when I was growing up, foreigners were really powerful, with a big head and a lot of chest hair, so I was surprised to see them in detail;" Office toilets are separated by white Chinese, which is a social reality. "

This distinction between China and foreign countries also makes this love more valuable and shocking.

Liu nancai, the protagonist of the story, thought about Zhang Dichen day and night, so he carved the word "God" on his arm and regarded me as a god. However, in the end, he did not wait for a perfect result-

When he was in a hurry, Liu Nacai occasionally remembered Zhang Dichen. What is he doing? Must be equally busy. Every time Liu Nacai reads him, he touches the word "God" on his right arm. My minister, my God, sees words like people. Once the war starts, he will go to war? Can you survive it? Liu Nacai is worried, but he is not desperate. He believes that with Zhang Dichen’s wit, even if the situation is chaotic, even if he is trapped in the worst situation, there is still a way to dig a tunnel for himself, and at least he can escape.

……

"On the way, I suddenly changed to a tattoo shop, stretched out my right arm, pointed to the word" God "and asked," Master Hong, is there any way to get rid of it? "

Master Hong shook his head and said, "Nanye, I’m sorry,no."

"No have to have! I don’t want to see this word again! " Liu Nacai stare nu way.

Master Hong didn’t expect Liu Nancai to suddenly get angry, so he stepped back in fear and said in a trembling voice, "Maybe … Master Nan, if you want to keep it, but don’t want to see it only, you can actually add some words before and after, for example, adding’ big’ in front of it to become a’ great god’; Or add a’ Ming’ after it and become a’ god’. This is a workaround. "

Liu Nacai frowned, hesitated, and couldn’t make up his mind for a moment. Master Hong reminded him to think about it slowly, and then turned to the kitchen to boil water and make tea. Lu Nancai stopped Master Hong and said, "Add more words, add more words." -When Lu Nancai left the third floor of Master Hong’s Tang Dynasty, the word "God" on his right arm became seven words: Hold your head three feet high and have a god.

Liu nancai’s god is still on his skin.

-Ma Jiahui’s "Leading Phoenix Tail"

Some media asked Ma Jiahui about the "Hong Kong Trilogy", but your last love letter to Hong Kong.

Ma Jiahui, who was originally sloppy, was noncommittal. "I just want to do what I am happy about."

The light of the future

After the return of Hong Kong, the young writers of the "post-1997" generation continued the urban writing of their predecessors and continued to create their own cities and legends.

For example, Keluo and Han Lizhu have published ten or more collections of short stories and novels. Other writers, such as Chen Zhihua, Xie Xiaohong, Li Weiyi and Zhang Wanwen, are also publishing their own works.

After decades of urban development, capital has shaped Hong Kong into a city with the largest number of skyscrapers (1,309) and the highest density of shopping malls in the world. Urban space is constantly encroaching on natural space, which has become a lingering haze for young writers in Hong Kong after 1997 to write about urban experience.

For example, Keluo’s City of Whales and Chen Zhihua’s "City of O" are called the continuation of Xixi’s My City, but they are brand-new versions of the times. Like their predecessors, they have given Hong Kong a new "flower name" and "nickname" and are also looking for a new way to speak for the city.

Basic Biology of Macrophages: From Origin to Function

Written by: immune meow with picky eaters

Source: gossip Immunology

●     ●     
 
Macrophages (English name: Macrophages, abbreviated M) are immune cells widely distributed in blood and tissues of the whole body.Macrophages can devour and kill intracellular parasites, bacteria, tumor cells, as well as self-aging and abnormal cells, and play an important role in immune defense, immune homeostasis and immune monitoring.Macrophages are a kind of phagocytes and belong to monocyte system.
 
Macrophages have been a hot research object for a long time because of their diversity and heterogeneity in tissue distribution.
 

one

The origin of macrophages
 

The evolution of species diversity and struggle for existence have produced a complex host defense system, which relies on natural immunity, first single-celled eukaryotes, and then adaptive immunity in tissues and developing eukaryotes. Natural immunity was first expounded at the end of 19th century, and Elie Metchnikoff introduced the word "macrophage", which means "macro = big and phage = eater”。 Monocytes/macrophages are a small group of white blood cells determined by their location, phenotype, morphology and gene expression profile.

Monocytes account for 4-10% of nucleated cells in normal peripheral blood. In blood, the half-life of monocytes is less than 20 hours. For many years, it has been assumed that macrophages are completely differentiated from circulating monocytes, but the recent morphological and functional differences between these cells refute this hypothesis.

Recent research evidence shows that macrophages in most adult tissues are sown before birth, and during embryonic development, they are transferred from.yolk sacIt has the ability of self-renewal and is maintained independently of monocytes. In addition,Each organ has its own unique combination of embryos and adult macrophages..

Embryonic macrophages participate in tissue reconstruction, while adult macrophages mainly assist host defense. In addition to these differences, we also observed that embryonic macrophages and adult macrophages coexist in many different organs.

2

Tissue distribution of different macrophages   

According to their anatomical location and functional phenotype, macrophages can be divided intoMicroglial cellosteoclastpm, spleen tissue cells and interstitial connective tissue, liver interstitial connective tissue and kupffer cells.

There are also different types of macrophages in the intestine, which have different phenotypes and functions, but work together to maintain tolerance to normal intestinal flora and oral antigens.

There are also different numbers of macrophages in the secondary lymphoid organs, including macrophages in the marginal area of spleen, which inhibit the natural immunity and adaptive immunity to apoptotic cells, and sinus macrophages under the capsule of lymph nodes, which remove the virus in lymph and start the antiviral immune response.

differentMacrophages exist in immune immune immune sites., such as the brain, eyes and testicles, these parts are inTissue remodelinganddynamic balancePlay a central role. These tissue-specific macrophages devour dead cells, debris, foreign antigens and materials, organize the inflammatory process, and recruit more macrophages as needed.

three

Plasticity and polarization
 

Macrophages are remarkable plastic cells, which can be obtained fromConversion from one phenotype to another.. Macrophage polarization is a process. Macrophages show specific phenotypes and make functional responses to microenvironment stimuli and signals encountered in each specific tissue.

Local cytokine environment can localize macrophage polarization. The two subsets of macrophages with different functions include classic activated or inflammatory (M1) and alternately activated or anti-inflammatory (M2) macrophages. This phenomenon of these two different M1/M2 phenotypes is called.Macrophage polarization.

M1 macrophageIt is usually induced by the recognition of Th1 cytokines (such as IFN-γ and T NF-α) or bacterial lipopolysaccharide (LPS). These macrophages produce and secrete high levels of proinflammatory cytokines TNF-α, IL-1α, IL-1β, IL-6, IL-12, IL-23 and COX-2, while the level of IL-10 is low.

Functionally, M1 macrophages participate in the elimination of pathogens during infection by activating nicotinamide adenine phosphodinucleotide (NADPH) oxidase system and then producing reactive oxygen species (ROS). Therefore, M1 macrophages have strong anti-microbial and anti-tumor activities, mediating tissue damage caused by reactive oxygen species, damaging tissue regeneration and wound healing. In order to prevent this kind of tissue damage, the anti-inflammatory effect of M2 macrophages inhibits the chronic inflammatory reaction by regulating the mechanism.

M2 macrophageSTAT6 is activated by IL-4 receptor α(IL-4Rα) and polarized by Th2 cytokines IL-4 and IL-13, which has anti-inflammatory effect. Besides IL-4 and IL-13, cytokines such as IL-10 can also regulate M2 polarization by activating STAT 3 through IL-10 receptor (IL-10 R).

IL-33It is a cytokine related to Th2 in IL-1 family and can induce M2 polarization. It is characterized by up-regulating arginase-1(arg-1), CCL 17 and CCL 24, thus mediating pulmonary eosinophilia and airway inflammation.

IL-21It is another Th2-related cytokine that drives M2 polarization. M2 macrophages have the characteristics of anti-inflammatory cytokines, which are characterized by low production of IL-12 and high production of IL-10 and TGF-β.

Functionally, M2 macrophages have strong phagocytosis, which can remove debris and apoptotic cells, promote tissue repair and wound healing, and promote angiogenesis and fibrosis. Therefore, generally speaking, M2 cells participate in Th2 response and parasite clearance, inhibit inflammation, promote tissue remodeling, angiogenesis, immune regulation, tumor formation and progress.

However, the M1/M2 phenotype does not reflect different phenotypic subsets of macrophages. According to the activation stimulus received, M2 macrophages can be further divided into four types.M2A, M2B, M2C and M2DDifferent subgroups of the composition.

M2aMacrophage subsets can be induced by IL-4 and IL-13, producing high levels of CD206, bait receptor IL-1 receptor II(IL-RII) and IL-1 receptor antagonist (IL-1RA).

Immune complex (ICs) and Toll-like receptor (TLR) agonists or IL-1 receptor ligands can induce M2b subgroup.M2bMacrophages simultaneously produce anti-inflammatory and pro-inflammatory cytokines IL-10, IL-1β, IL-6 and α-α.

M2cCells were induced by glucocorticoid and IL-10, and showed strong anti-inflammatory effect on apoptotic cells by releasing a large amount of IL-10 and transforming growth factor-β.

Finally, TLR agonist induced the fourth M2 macrophage through adenosine receptor agonist.M2d.

The activated receptor of adenosine then inhibits the production of pro-inflammatory cytokines, induces anti-inflammatory secretion of cytokines (high IL-10, low IL-12) and vascular endothelial growth factor (VEG F), thus providing a drug withTumor associated macrophages (TAMS)The angiogenic characteristics of the characteristic. M2 macrophages exposed to M1 signal, or conversely, induced differentiated macrophages to "repolarize" or "reprogram" is another evidence that they have high functional plasticity and can potentially pursue therapeutic goals.

four

hugeMigration of phagocytes

Monocytes and macrophages migrate to the site of inflammation or injury to eliminate the initial inflammatory signal and ultimately promote wound healing and tissue repair.

This process is mainly initiated by pathogen-related molecular patterns (PAMPs) (released from invasive pathogens) and damage-related molecular patterns (DAMPs) (released from damaged or dead cells to cope with infection and injury).

In addition, antigen can activate memory T cells in tissues through secretion.manyInflammatory cytokines and chemokines are used to trigger the recruitment of macrophages. Chemokines directly participate in the migration and activation of monocytes through endothelium, and monocyte chemoattractant protein -1 (MCP-1) is a monocyte chemotactic factor, which participates in the occurrence of inflammation and induces monocyte chemotaxis and migration by interacting with CC chemotactic factor 2(CCR2) on monocytes. MCP-1 is mainly secreted by activated fibroblasts, endothelial cells, vascular smooth muscle cells (VSMC), monocytes and T cells. MCP-1, together with IL-8 or CXC ligand -8(CXCL-8), can trigger the firm adhesion of monocytes to vascular endothelial cells under blood flow conditions. Monocyte adhesion and migration across endothelium through activated venule wall is a basic immune response, which depends on the expression of adhesion molecules of chemical mediators on the surface of vein endothelium.

These adhesion molecules belong to four families:SelectinIntegrinImmunoglobulin superfamilyandMucin-like glycoprotein.

five

Antigen presentation

Antigen presenting cells, mainly macrophages, are the outposts of the immune system that starts and regulates immune response. An important feature of macrophage biology is the capture, endocytosis and expression of self or foreign antigens, which providesThe connection between innate immunity and adaptive immunity.

Macrophages reside in surrounding organs, where they monitor surrounding tissues for invading pathogens. They alert the immune system to the presence of pathogens by engulfing them, processing their antigens and presenting peptide fragments that bind to human leukocyte antigen (HLA) molecules. After antigen treatment, macrophages migrate to T cells and stimulate them. Activated macrophages express high levels of costimulatory molecules and antigen presenting molecules on their surfaces, such as CD 80, CD 86 and MHCⅠ ⅰ and ⅱ molecules. Mixed Leukocyte/Lymphocyte Reaction (MLR) is used as a basic test for determining the function of macrophages, because it measures the proliferation ability of macrophages to allogeneic T cell populations.

six

Production of cytokine and chemokines

Interleukin is a kind of cytokine, which is involved in inducing adhesion molecules, matrix metalloproteinases (MMP), angiogenic factors and signal pathways, such as nuclear factor kappa B(NF-kB) and signal transduction and transcription activator (STAS) involved in tumor invasion and angiogenesis.

Activation of M1 macrophages can induce proinflammatory cytokines., including TNF-α, IL-1α, IL-1β, IL-6, IL-12, IL-18 and IL-23; Produce nitric oxide (NO), reactive oxygen species (ROS) and RNS;; Antigen presentation; Expression of CC chemokine receptors CCR1 and CCR5; Promoting T-helper type 1 (Th1) and Th17 responses provides an effective mechanism for killing.

Obviously, M1 and M2 macrophages have different chemokine profiles, while M1 macrophages expressing Th1 cell chemokines, such as CXCL9 and CXCL10.

M2 macrophages express chemokines.CCL17, CCL18, CCL22 and CCL 24. M1 macrophages express inflammatory cytokines TNF-α, IL-1β and IL-6, and together with costimulatory molecules CD 40, CD 80 and CD 86, they up-regulate MHCⅡ class II molecules to promote cytotoxic adaptive immunity.

M1 macrophages express Th1- and Th17- polarized cytokines IL-12, IL-23, IL-27 and Th1- aggregation chemokines CXCL 9, CXCL 10 and CXCL 11. On the contrary, M2 macrophages support the resolution of inflammation by transferring gene expression to anti-inflammatory molecules such as IL-10, TGF-β, IL-1R1Ⅱ and IL-1Ra. M2 macrophages also express a large number of endogenous receptors, including scavenger receptor CD 163, stabilizer -1 and type C lectin receptor CD 206, CD 301, Dectin-1 and CD 209. In addition, M2 macrophages recruit Th2, regulatory T cells (Tregs), eosinophils and basophils by secreting chemokines such as CCL 17, CCL 18, CCL 22 and CCL 24..

seven

Macrophage apoptosis

Apoptosis is a normal, physiological and necessary process of cell selection and survival, eliminating and removing unnecessary cells, such as aging, damaged, genetic mutation and virus-infected cells; In fact, anti-apoptosis can promote malignant transformation of normal cells.

At present, it is known that macrophage apoptosis is related to various stages of the disease related to the decline of pathogen activity, which can be regarded as a natural immune defense mechanism and strategy for the host to limit infection against intracellular pathogens.

On the contrary, many cellsPathogens have the ability to kill infected cells., destroy the host pathway, inhibit cell apoptosis, leading to necrosis. This strategy can makePathogens escape the host’s immunity and infect other nearby or distant cells.. These apoptotic infected cells also provide a link between innate immunity and acquired immunity. When professional APCs absorb apoptotic vesicles, this connection begins when bacterial products and pathogenic antigens enhance T cell activation. Similarly,Pathogens inhibit apoptosis and promote necrosis.It also impairs the presentation of bacterial antigens, which may be the mechanism of immune escape.

In atherosclerosis, macrophages die by reducing the number of cells in the lesion, which is beneficial to reduce the lesion area. In the progress of atherosclerosis and other diseases, the phagocytosis of M2 macrophages solves the problem of apoptosis and its adverse effects. This unique functional feature of M2 macrophage is caused byHigh level of scavenger receptorExpress support.

Macrophages phagocytize debris, injured cells, dead cells and apoptotic cells, and inhibit macrophages from producing pro-inflammatory cytokines such as tumor necrosis factor-α, interleukin -1β, interleukin -6 and interleukin -8. The mechanism involves autocrine or paracrine of transforming growth factor -β(TGF-β), thus inhibiting further recruitment of monocytes and macrophages.

In addition, the phagocytosis of apoptotic cells inhibits the production of pro-inflammatory IL-12, IL-23 and IL-27 and stimulates the production of anti-inflammatory IL-10.

By limiting the phagocytosis of local inflammation, it can also protect tissues from harmful pro-inflammatory reactions, death, injury and the immunogenic content of dead cells, and throughNecrosis after apoptosis to protect the growth of lesions.

In the late stage of atherosclerosis, the phagocytic function of apoptotic cells is seriously damaged, which leads to the aggregation of macrophages and vascular smooth muscle cells, which eventually blocks the decomposition of inflammation and promotes local necrosis, inflammatory state and plaque instability.

Understanding the exact mechanism of pathogen inhibiting apoptosis can avoid natural immunity and adaptive immunity, which provides a new strategy for optimizing treatment. The idea of manipulating the host or bacterial pathway to induce more cell apoptosis, "apoptosis-promoting therapy", may help to produce a more effective immune response.

Macrophage metabolism

Recent evidence shows that metabolism plays an important role in the formation of macrophages and the obvious polarization phenotype. Under normal, physiological and pathological conditions, macrophages face an oxygen gradient.Macrophages adapt to hypoxia by shifting their metabolic pathways to glycolysis.. In addition, the activation of hypoxia-inducible factors (HIF)-1 and -2 caused profound functional changes, including the expression of chemokines and chemokine receptors, such as CXC chemokine 4(CXCR 4), CXCL 12, angiogenesis factor and vascular endothelial growth factor (VEGF)(Biswas and Mantovani, 2012; Orihuela et al., 2016). Therefore, macrophages help to coordinate the response of tissues to oxygen gradient and hypoxia conditions.

Macrophages M1 and M2 can obviously regulate the metabolism of glucose, amino acids, iron and folic acid.After macrophage activation, its metabolic pathway changes from oxidation to glycolysis.solve. Under the action of M1 stimuli (such as LPS, Th1 cytokines and IL-12), they showed a metabolic transformation to anaerobic glycolytic pathway, while M2 stimuli (such as IL-4 and IL-13) had little effect. Macrophages activated by IFN-γ and L-PS are often associated with acute infection, so it is necessary to trigger strong antimicrobial activity quickly in hypoxic microenvironment. In this case, the anaerobic process such as glycolysis is the best way when energy is needed. Interferon-γ and lipopolysaccharide strongly induce glucose uptake and inhibit fatty acid uptake and oxidation. Therefore, glycolysis metabolism is enhanced and mitochondrial activity is decreased.

On the contrary,M2 macrophage functions, such as wound healing and tissue repair, need continuous energy supply.. This requirement is made byGlucose oxidative metabolism and fatty acid oxidationProvided, andFatty acid oxidation is the most important metabolic pathway of M2 macrophages.. M2 macrophage has the characteristics of high mitochondrial activity and oxidative phosphorylation. They show enhanced respiratory activity based on fatty acid β oxidation. Both metabolic pathways are up-regulated in the process of macrophage activation, but glycolysis is the main metabolic pathway, which can produce DNA and cell membrane synthesis substrates and promote the growth and differentiation of monocytes. It is another possibility of glycolytic metastasis of M1 macrophages to produce rapid and optimal response at the infected site.

In addition, the accumulation of citric acid in M1 macrophages is essential for the production of pro-inflammatory mediators NO, ROS, RNS and prostaglandin. Another important aspect is the metabolism of amino acids closely related to the functional phenotype of macrophages. M1 macrophages are characterized by the expression of inducible nitric oxide synthase (iNOS).The production of NO is an important anti-microbial effect. M1 macrophages are active, while M2 macrophages do not produce NO.. On the contrary, they express high levels of Arg-1 and play a role in catalyzing the production of polyamines, which are necessary for collagen synthesis, cell proliferation, fibrosis and other tissue remodeling functions. Interestingly, the production of polyamines is reported to be the driving factor of M2 polarization.

In addition, there are significant differences in iron metabolism between M1 and M2 macrophages. Although M1 macrophages express a large number of iron storage proteins, such as ferritin, the content of iron porphyrin they express is low, and ferritin is the export of iron. Compared with M1 type macrophages, M2 type macrophages have lower ferritin content, but higher ferritin content. This different iron metabolism may be related to its function. Because iron is necessary to support the growth of bacteria, the retention of iron in M1 macrophages is a kind of bacteriostasis and supports the host’s protection against infection. On the contrary, the iron released by M2 macrophages is beneficial to tissue repair, but it can cause tumor growth and metastasis.

Metabolic adaptation is an important aspect of macrophage polarization and its functional activities.

MicroRNA involved in macrophage polarization

MicroRNA plays an important role in many aspects of macrophage biology, thus affecting many biological and pathological conditions, such as monocyte differentiation and development, macrophage polarization, infection, atherosclerosis, tumor growth, inflammatory activation, cholesterol homeostasis, cell survival and proliferation, and phagocytosis.

MiRNA-24, miRNA-30b, miRNA-142-3p and miRNA-199a-5p can inhibit the differentiation of monocytes into macrophages.

M1 macrophage polarizationMiRNA-125, miRNA-146, miRNA-155, miRNA-7a/f and miRNA-378 are needed, andM2 polarizationThen miRNA-let-7c/e, miRNA-9, miRNA-21, miRNA-146, miRNA-147, miRNA-187 and miRNA-223 are needed.

In addition, miRNA-342-5p promotes NO synthesis, and IL-6 provides pro-inflammatory signals for macrophages. Although miR-21 has been proved to have both pro-inflammatory and anti-inflammatory effects, its anti-inflammatory effect is more prominent. MiR-155 and miR-142-3p inhibited the proliferation of macrophages compared with let-7a. MiR-155 can promote and prevent apoptosis at the same time, while miR-21 and let-7e negatively regulate the apoptosis of macrophages.

RCEP takes full effect. Journalists visit the certificate of origin examination center to see the results of tariff concessions.

CCTV News:Regional Comprehensive Economic Partnership Agreement (RCEP) is a trade agreement signed by 15 member countries including China, Japan and New Zealand. Today (June 2nd), with the entry into force of RCEP for the Philippines, all 15 member countries have completed the entry-into-force procedures and mutually implemented tariff concessions, and the agreement has entered a new stage of full implementation.

In the early morning of June 2, at the Certificate of Origin Examination Center of RCEP Pioneer Innovation Experimental Base in Qingdao, Shandong Province, customs officers issued RCEP certificates of origin for a batch of 5.6-ton container liquid bags exported to the Philippines.

CCTV reporter lin li:This one in my hand is the certificate of origin of RCEP. From now on, the option of the Philippines has been added to the column of exporter’s declaration on the certificate, which means that all 15 member countries of RCEP have completed the entry into force procedures and implemented tariff concessions to each other. With this certificate in my hand, the enterprise can reduce the import tariff of more than 2000 yuan when importing this ticket of goods in the Philippines.

Li Qianqian, Assistant General Manager of a Technology Co., Ltd. in Qingdao, Shandong Province:(Products) can enjoy the tariff reduction from 3% to zero. Last year, the company exported about 4 million yuan to the Philippines, and our export of orders to the Philippines this year is expected to increase by 10%. (RCEP) can bring about 80,000 yuan in tariff concessions to enterprises.

The data shows that China has become the largest trading partner of the Philippines for six consecutive years. In 2022, the total value of import and export commodities between China and the Philippines reached 585.28 billion yuan, a year-on-year increase of 10.6%. After RCEP comes into effect for the Philippines, the Philippines will add zero-tariff treatment to Chinese automobiles and parts, some plastic products, textiles and garments.

Bi Haijun, Director of Customs Department of Qingdao Customs:After RCEP completes the tax reduction process, the goods imported from the Philippines can be sold in China — On the basis of the ASEAN Free Trade Agreement, the tariff cost will be reduced by more than 30 million yuan.

Interview with Zhu Yanping: Movies need grounding gas, don’t be superstitious about New Year’s files.


Yen-Ping Chu

    Movie network news(Photo/Report Group of Directors’ Summit in the Mainland, Taiwan and Hong Kong) The 11th Cross-Strait and Hong Kong Film Directors Seminar and the 2010 China Film Directors Annual Commendation Conference continued to be held in Sanya. On January 12th, Zhu Yanping, a Taiwan Province director who has been developing in the mainland in recent years, accepted an exclusive interview with Movie Network. He thought that both the box office and the word-of-mouth directed by himself and Xiaogang Feng failed because they collected too many Hollywood elements, but they didn’t meet the local flavor. He also laughed and said that he was not superstitious about New Year’s Eve.

Zhu Yanping said that Xiaogang Feng benefited him a lot and found the reason for the failure of "Thorn Ling".

    Movie Network: As one of the earliest directors who cooperated with the mainland, your "stab mausoleum" has a miserable box office, but it has a good record, with a box office of over 100 million yuan. Have you already explored the tastes of mainland audiences?

    Zhu Yanping: Actually, I was confused at one time. Today, I was suddenly enlightened by director Xiaogang Feng’s words. Xiaogang Feng said that all his films only included the elements of selling money in Hollywood, but only this film didn’t sell (money), and the same is true of the thorn mausoleum.

    I think we should shoot Chinese’s own stuff. It’s a new attempt for me to put Hollywood elements into it. People don’t even think I shot it when they read The Thorn Mausoleum. Another important reason for the failure of The Thorn Mausoleum is the temporary advance of the schedule, which made it impossible for Jay Chou and Lin Chi-ling to promote it. This time, I adjusted a direction to shoot "Laughing Rivers and Lakes", and Zhao Benshan and I hit it off. Zhao Benshan has always wanted to find a director who can make comedies, and I have always wanted to find an actor who can perform comedies. We have a very happy cooperation.

    Movie Network: The movie you directed is the Spring Festival, while "Thorn Ling" and "Laughing Jianghu" are both Chinese New Year movies. Is it because these two movies are easy to sell?

    Zhu Yanping: Actually, personally, I don’t want to be on the Lunar New Year’s Eve. I don’t think it’s a good schedule, because the competition is too fierce, the military strategists are fighting for it, and everyone is beating their heads off. I made three movies in the mainland, basically in this schedule, which is really a bit unbearable.

    I hope I can make a movie that will be shown in other slots, and I think the box office of 200 million yuan will definitely not run away. I think it’s normal to compete with two movies in a schedule, but it’s too tragic to compete with four movies in December. Just when you should be selling, the cinema schedule put you down, alas! I think the summer file and the eleventh file are also very good. Of course, at present, I am still in the exploratory stage, and I don’t know which schedule is the best.

Learning from Hollywood’s product placement, there is no trace of new people breaking files because the film is superstitious about "old people"

    Movie Network: Xiaogang Feng has been criticized by the audience for too many product placement advertisements. What do you think of more and more product placement advertisements in movies?

    Zhu Yanping: To be honest, product placement is necessary. A movie must take commercial factors into account. The more you invest in product placement, the more money you spend on making movies. I think it’s mainly about how to combine product placement with movies. For example, in Hollywood movies, there are more product placement than us, but no audience will count how many products have been placed. People won’t even notice this problem, so it’s very important to implant products without trace.

    Movie Network: No matter in the Mainland, Hongkong or Taiwan Province, there is a problem that new actors are cut off at present. What do you think is the reason?

    Zhu Yanping: It is true that young actors are cut off. Up to now, Hong Kong is still Louis Koo, Donnie Yen, the mainland is still Chen Kun, and so on. Relatively speaking, Taiwan Province is even better. Recently, there are Ehan Juan and Mark Chao. In fact, Taiwan Province has trained many film actors, including Shu Qi, Takeshi Kaneshiro, Lin Chi-ling, Jay Chou, etc. However, after these actors became popular, their prices soared, and Taiwan Province films could not afford them immediately because of low investment, so they went to the mainland to make blockbusters, which is also the sorrow of Taiwan Province film industry.


Zhu Yanping: Movies should be grounded.


Taiwan Province movies are small and beautiful, and the director doesn’t know how to spend money to go out, which is the biggest crux.

    Movie Network: In your opinion, what is the urgent problem to be solved in Taiwan Province film industry at present?

    Zhu Yanping: Taiwan Province’s films are small and beautiful, with an investment of about two or three million RMB. They are very creative and of high quality. I dare say that if there is only 2 million investment, no one can shoot better than director Taiwan Province. For example, the investment in a film in the mainland is often hundreds of millions of yuan, and if director Taiwan Province wants to get the money, he may not know how to spend it.

    However, because the films are small and too localized, Taiwan Province films are mainly shown in China, and their influence in other places is relatively small. I think the urgent problem for Taiwan Province films is how to go abroad, at least in the whole Chinese-speaking region.

    Film Network: At present, there are not many directors from Taiwan Province coming to the mainland to make films. Do you think there will be more cooperation between filmmakers from both sides of the strait in the future?

    Zhu Yanping: Yes, I am the only director in Taiwan Province now. I am Depth Charge. I didn’t get much support when I filmed "The Thorn Mausoleum", but the Taiwan Province media coverage of "Laughing Jianghu" was overwhelming, and more and more Taiwan Province directors began to pay attention to cooperation with the mainland. I believe that more and more Taiwan Province directors will come to the mainland to film soon.

    Movie Network: What do you think Taiwan Province’s director should do to film in the Mainland?

    Zhu Yanping: Grounding gas (laughs)! For me, it’s not difficult to meet the local conditions in Taiwan Province, but it’s a bit difficult to meet those in the mainland. We need to know more about mainland culture, but I think the prospect is worth looking forward to. You see there are still language problems in Hong Kong and the Mainland, and Taiwan Province has an advantage in this respect, so I think director Taiwan Province will adapt faster!

According to the Survey on Wealth Values of College Students in China released in 2017, mobile payment accounted for nearly 92% of the post-90s generation in China in 2016. The per capita payment of China college students on Alipay (including data on transfer, online shopping consumption, red envelopes, financial management, etc.) is about 40,839 yuan, an increase of 97% compared with 2015. This is still the data of Alipay platform five years ago.

For contemporary college students, making money is more like a passive behavior of "people are in the rivers and lakes and can’t help themselves".

This year’s college students will spend the most money and make the most money.

For most students, it is difficult to reach home under the self-awareness of adults, and part-time job has become the choice of many people.

exceptBeing able to earn pocket money is also a fresh experience for college students in ivory towers.

He Shijie, an undergraduate student at Beijing University of Posts and Telecommunications, started his freshman year in 2017."Hello, teacher. My name is He."In bilibili, I uploaded a video related to digital technology, and explained it in a simple and humorous way, which made people praise it again and again.

The number of single videos played exceeded 20 million, and the university participated in Hunan Satellite TV’s "Informal Talks" and interviewed Apple CEO Cook.

With a video of more than one minute, Loctek soared by 14%, equivalent to 550 million shares; Among the major e-commerce platforms, several lifting tables mentioned in the video are out of stock.

This advertisement placement has also brought rich income to He. According to a person familiar with the matter, the market price of this video of He is less than 3 million yuan.Even if he does it once every two or three months, he earns tens of millions of yuan every year.

In fact, at present, college students have all kinds of strange ideas and like to pursue novel things, and those novel ways of making money, such as short video, live selling goods and dubbing, which are developed based on short video platforms, have also become the first choice for college students to work part-time, and their income is relatively higher.

If you are in Little Red Book, Tik Tok or bilibili, search."College students earn more than 10,000 yuan a month"You will find that there are many bloggers who have earned tens of thousands of dollars a month through part-time work during their school days.

There are even post-00 s who have multiple jobs and use school time fragments to continuously improve their capital income.

However, more college students rely on platforms such as Tik Tok and Xiaohongshu to realize the circle powder.

It is true that for college students, there are countless part-time jobs that can be realized by only one mobile phone.

Released by Tik TokTik Tok University Student Data Report 2020It shows that in 2020, college students in Tik Tok released video broadcasts, with a total of more than 311 trillion times, 118.4 billion likes and 2.7 billion shares.

Dormitory culture, college students’ daily life, graduation, starting school … These college students have become the source of college students’ daily income.

Short videos are just a way for college students to make money.

Before the Internet was developed,There are many college students scrambling to distribute leaflets, waiters, tutor, promote sales, and even novel scribes.However, the general commission is not high and it takes a lot of time, so it is difficult for college students to really get rich from it.

However, with the rise of short, flat and fast platforms such as Tik Tok, Aauto Quicker and Xiaohongshu, there are also many occupations, such as:Live broadcast with goods, beauty bloggers, wear bloggers, food bloggers, etc.

On the premise of low threshold and low cost, these "within reach" ways to make money have become the options for college students to earn extra money after school and realize the freedom of pocket money.

According to statistics,In 2021, 83.9% of college students in China’s first tier cities have part-time jobs after class.; 81.8% college students in second-tier cities have extracurricular part-time jobs; Third-tier cities have a higher proportion of extracurricular part-time jobs, reaching 86.1%; The proportion of extracurricular part-time college students in fourth-tier and below cities is 80.0%.

howeverFrom the perspective of the little red book platform, there are also many internet part-time sharing posts.

Among them, there are more than 30 thousand notes on "sending models", and more than half of them are sharing posts about college students’ experiences as part-time sending models; There are more than 60,000 notes on "College Students Live with Goods"; More than 5,000 notes on "Handmade by College Students"; There are also 5,900 notes on "Student Party Knowledge Sharing".

On the other hand, the topic of "student party sideline" played on the Tik Tok platform is as high as 276.2W;;# College Students’ Entrepreneurship # The number of topics played was 3.55 billion.

In addition, according to the data released by Cass,"2019 Beauty Short Video KOL Marketing Report"According to the survey, among the beauty bloggers in Tik Tok, Aauto Quicker and bilibili, the age of 18-24 accounts for the most, which means that there are not a few student parties whose sideline business is beauty.

Seeing the cheap and easy-to-use college students’ resources, smart capital began to act, and more and more MCN set their sights on colleges and universities.

We searched the employment networks of Shanghai Normal University, Nanjing Communication College, China Communication University and other universities, and found that "online celebrity" jobs such as recruiting celebrities, talents, UPmasters and anchors after the MCN season also appeared in the recruitment list with high profile.

The 2021 campus recruitment of MCN organization’s bee colony culture has launched the positions of beauty fashion, life orientation and talent to short video talents. Elephant mutual entertainment also recruits full-time anchors for college students.

theseIt is not without reason that institutions take a fancy to college students.

For example, about 70% of the traffic of talent under the banner of Ivy Culture is concentrated in bilibili, while the audience in bilibili is mainly young people under the age of 23, so the creators of young groups on campus will know more about them.

Under the promotion of professional MCN institutions, there are indeed college students who have done "online celebrity" in circles.

Funny humor UP main self-invited volume Miki and anime blogger UP main star Youye both entered MCN institutions during their college years, and were discovered and hatched by the company into online celebrity Talent, and now they are all big V’s with millions of fans.

In addition to college students who are out of the circle, there are many college students who get rich by "labor".

Xiaomi, a college student in Beijing.A wide range of hobbies, the pursuit of quality of life, spending as high as seven or eight thousand or even tens of thousands a month. More than half of this is earned by oneself.

From the freshman year, she worked part-time, as a tutor, delivering food, sorting express at the express station during the Double Eleven, playing games, and helping others walk their dogs at night …At the busiest time, she took seven part-time jobs at the same time.

Get up early in the morning to translate subtitles for movies, then go to class, deliver takeout for 2 hours after class, sing in folk bars at night, and help others walk their dogs when they come back. They are busy until eleven or twelve o’clock, and they will also go to the secret room to escape npc…… on weekends … The total income can reach about five or six thousand per month, and sometimes tens of thousands.

Yu Xia, a college student in ShanghaiSenior script killer fans often go offline to carpool and play books. Because of their clear logic and expression, they are taken by the boss of the script killer shop and work part-time as a DM on weekends.

Because of her extroverted personality and good looks, she became a top-level DM in the store. She can host three screenplay killings in a row on weekends, but the boss promised her a sharing mode, so she can earn nearly 1000 yuan a day.

She now has a plan to kill the author as a script, and plans to write her own script and sell the copyright.

She herself said that when DM only earns some pocket money temporarily, creation is her goal, and DM allows her to jump out of the player’s perspective and feel as much as possible what everyone is interested in and what interesting mechanisms are, which is also helpful for creation.

These accumulated experiences and Internet traffic can still be the key to widening the distance between peers in the future.

3、College students’ view of money has changed.

For contemporary college students, making money is more like a passive behavior of "people are in the rivers and lakes and can’t help themselves".

We can sum it up as two mountains where "money" is pressing on college students:Freedom of consumption and pressure from classmates.

Going to college is a watershed for personal consumption. In high school, food, clothing, housing and transportation were basically solved within the school, and there was not much extra cost. But after going to college, all kinds of consumption items came.

Freedom of consumption has become the premise of obtaining most other freedoms.

What brand of clothes to wear, what brand of mobile phone and computer to use, which online celebrity restaurant to eat, what kind of exhibitions to watch, and what kind of APP members are … Differences in consumer goods have almost become an important way for college students to show their differences from others.

picture

Xiaomi in Beijing gives her daily consumption record: it costs 3,000 yuan to eat every month; Falling in love, buying gifts for friends, and attending class reunion are also at least 2,000 yuan per month; Cosmetics and clothes also need about 1000 yuan every month …

Peer comparison also makes college students more active in making money.

The Internet allows people to peek into other people’s lives. Under the general environment of "everyone is rich and beautiful, and everyone is not short of money" in Tik Tok and Xiaohongshu, college students are passively involved, and others who are beautiful find that others are more beautiful, and those who make more money find that others earn more.

I went to 985 and 211, only to find that I had nothing.The author who grew up in a small town had excellent grades since childhood, but after being admitted to a prestigious school in a big city, he found that he was behind his classmates in appearance, family, contacts and vision-"The more difficult it is to climb, the more painful it is to see."

College students’ involution is invisible, and earning money part-time is to prove themselves and relieve anxiety.

picture

"Part-time job" brings not only "pocket money freedom" to universities, but alsoAfter entering the society, it has become one of the biggest reasons to open the distance between peers.

For college students, when everyone is in school, there may not be much difference for the time being. Even if some people work part-time and some people study hard every minute, these can’t give them too much visual impact, but if they don’t work hard, once they leave the society, they will immediately go to two worlds.

This common and immediate example can be found everywhere among many college students.

In fact, let’s not talk about right and wrong. If you want to get more pocket money to improve your quality of life, you can get it by part-time in your spare time, and you can also accumulate work experience while being self-sufficient.

Because college students are young, they are curious about the unknown world and want to keep exploring and making progress, butIt’s not that they can’t bear hardships, but they don’t want to suffer meaningless and imposed hardships.

This is reflected in the way they make money.

Revealing the fastest supercomputer in the world: it takes 32 years for the earth to turn on the phone for one minute.

  Xinhua News Agency, Nanjing, June 20th: One minute on the phone counts as 32 years — — Revealing the World’s Fastest Supercomputer "Shenwei Light of Taihu Lake"

  Xinhua News Agency reporters Jiang Fang and Cai Yugao

  On June 20th, the International Supercomputing Conference (ISC) in Frankfurt, Germany announced the new TOP500 list of global supercomputers. The "Shenwei Taihu Light" developed by the National Center for Parallel Computer Engineering and Technology won the first place with nearly three times the operation speed. What’s more exciting is that the system has realized the localization of all core components including the processor.

  How fast is the computing speed of the new overlord of supercomputers? What does full localization mean? Has China Supercomputing reached the top of the world? Xinhua News Agency reporter walked into the Wuxi Center of National Supercomputing, which is responsible for the operation and maintenance of the system, and unveiled the mystery of "Shenwei Taihu Light" for you.

  What’s the feeling of the fastest computing in the world? One minute of operation is equivalent to 32 years on earth.

  The peak performance of the system is 125.436PFlops, ranking first in the world;

  The continuous performance is 93.015PFlops, ranking first in the world;

  The performance-to-power ratio is 6051 mflops/w, which is still the first in the world.

  The news from the International Supercomputing Conference is confusing just by looking at the data.

  "Simply put, the one-minute computing power of this system is equivalent to 7.2 billion people around the world using calculators to calculate continuously for 32 years; If mainstream laptops or personal desktops produced in 2016 are used as a reference, ‘ Light of Taihu Lake ’ It is equivalent to more than 2 million ordinary computers. " Yang Guangwen, director of Wuxi National Supercomputing Center, introduced.

  Walking into the National Supercomputing Wuxi Center, in a room of 1,000 square meters, the reporter saw the "real body" of "Shenwei Taihu Light":

  It consists of 40 computing cabinets and 8 network cabinets. Each computing cabinet is slightly larger than a household two-door refrigerator. When the cabinet door is opened, four super nodes consisting of 32 computing plug-ins are distributed in it. Each plug-in consists of four operation node boards, and one operation node board contains two "Shenwei 26010" high-performance processors. One cabinet has 1024 processors, and the whole "Shenwei Taihu Light" has 40,960 processors.

  "Each processor is equivalent to the computing power of more than 20 commonly used laptops, and more than 40,000 pieces are assembled together, and the speed can be imagined." Yang Guangwen said.

  Global supercomputing, only fast and unbreakable. The significance of working on supercomputing research is not only "speed war", but more importantly, winning "application war".

  Fu Haohuan, deputy director of the National Supercomputing Wuxi Center, introduced that relying on the "Shenwei Light of Taihu Lake", the research team with the theme of Tsinghua University realized the numerical simulation of the global 10-kilometer high-resolution earth system for the first time, which will comprehensively improve China’s ability to cope with extreme climate and natural disasters; The numerical simulation results of the return path of "Tiangong-1" by the National Computational Fluid Dynamics Laboratory are exciting and will provide accurate predictions for the smooth return of "Tiangong-1". The drug screening and disease mechanism research carried out by Shanghai Institute of Drugs completed the routine calculation in just two weeks, which greatly accelerated the progress of drug design in leukemia, cancer and avian influenza … …

  From "glass room" to "restricted sale" of 25 square centimeters, completely breaking the 30-year technical blockade.

  Thirty years ago, supercomputer users in China had a mysterious "glass room": Americans sold a supercomputer to China, wrapped it in opaque glass, and technicians from China were not allowed to enter without authorization.

  Professor Wang Lanning from the Institute of Global Change and Earth System Science of Beijing Normal University still remembers this "technology enclave" in China. "Only a few authorized scientists in the country can enter the glass room, and it is under the supervision of Americans. Once the program runs, the machine is locked back to the glass room immediately. The so-called supercomputing speed seems to be a high-performance computer at best today, but it was an unattainable peak for China at that time. "

  In the 1980s, China has gradually entered the ranks of countries that independently design and manufacture supercomputers, but the shortcomings of key components and technologies such as core processors can only be controlled by others, which directly leads to the fact that although China is a "big buyer" of foreign supercomputers, it cannot have the matching "bargaining power".

  Stepping into the "Twelfth Five-Year Plan", with the key support of the National 863 Project, China’s supercomputing development has continuously made breakthroughs. "Tianhe II" won "six consecutive championships", while the list of top 500 supercomputers in the world is getting longer and longer, which has aroused the vigilance of the United States. In April, 2015, the US government announced that four China organizations related to supercomputers were included in the restricted export list, with the purpose of locking up the rapid development of supercomputers in China through restricted sales.

  It is the incentive brought by this blockade that has enabled China to make great efforts to develop fully localized "Shenwei" series supercomputers until it reached the top of the international list.

  As a result, the thin block "Shenwei 26010", which is only 5 cm square, has not only become the heart of "Shenwei Taihu Light", but also become a sharp weapon for China’s independent research and development to break the 30-year technical blockade. Between the square inches of 25 square centimeters, 260 computing cores and billions of transistors are integrated, reaching more than 3 trillion calculations per second. The computing power of a single chip is equivalent to three supercomputers ranked first in the world in 2000.

  Yang Guangwen said that there has always been a controversy about whether we should independently develop the core processor. Some people say that if we haven’t done it for so many years, we should simply stop doing it and "adopt" one. There are also voices that the high-speed rail model of introduction, absorption and re-innovation is very good. Why do we have to close the door and engage in independent ecology? "If we don’t adhere to the completely independent ecology, we can’t do it for more than ten years, and then we can’t do it for more than ten years. It is impossible to have the great power of core indicators going hand in hand today." Liang Jun, deputy director of the National Parallel Computer Engineering Technology Research Center, said.

  From the "six consecutive championships" to the first billion China supercomputing, there is still a gap from the top of the world

  Supercomputers, known as "the sharp weapon of the country", are the embodiment of the comprehensive strength of the country’s science and technology. From high-end materials, to life sciences and biotechnology, to deep-sea exploration and space technology, it is inseparable from the support of supercomputing. As soon as the good news came out, some people thought that China Supercomputer had "firmly" stood at the top of the world from now on. Is that really the case?

  Yang Guangwen said that it is undeniable that the success of "Shenwei Light of Taihu Lake" indicates that China’s supercomputer research and development capability has already reached the world’s leading level, but there is still a clear gap between China and developed countries in terms of technical reserves and system stability.

  The battle for speed is the most direct confrontation in the field of supercomputing. Compared with the glory of "Tianhe No.2" and "six consecutive championships", it is extremely difficult for Shenwei Taihu Light to occupy the first place in the world for a long time. In July last year, the United States launched the "National Strategic Computing Plan" with the goal of building the fastest computer in the world by 2025.

  "In the next five to ten years, from one billion times per second to one billion times per second is the decisive place for supercomputer development." Relevant researchers from the National Center for Parallel Computing said that although supercomputing countries are deploying, there are many key technical links that need to be solved. Taking energy consumption as an example, the annual electricity consumption of Shenwei Taihu Light reaches 15 MW, which is equivalent to the electricity consumption of three Tsinghua University. Even if billions of times can be achieved with the existing technology, the energy consumption will be very amazing.

  More importantly, no matter how fast the speed is, the development of supercomputing is always for "application", and this is still the shortcoming of the current development of supercomputing in China.

  Zhang Jian, a researcher at the Computer Network Information Center of the Chinese Academy of Sciences, said that China’s ability to solve problems with supercomputing systems has been insufficient for a long time, and related commercial application software is still monopolized by foreign countries, and it needs to be further improved in software development, application development and personnel training. Only by transforming the advantage of "making good" into the advantage of "making good use" can we truly promote industrial innovation and upgrading.

Heavy! Huawei HarmonyOS 3.1 was launched this month, and the first batch of 6 mobile phones started early adopter recruitment.

According to Huawei’s latest announcement, HarmonyOS’s OS 3.1 system will officially announce the upgrade plan, but according to the current news, HarmonyOS’s OS 3.1 is really different, which brings many different places. Today, it was reported that Huawei HarmonyOS 3.1 was launched this month, and the first batch of Huawei Mate 50 Pro, Mate 50 RS Porsche Design, Mate 50, Mate 50E, nova 10 and nova 10 Pro launched the new feature version Beta of HarmonyOS 3 for early adopters.

Personally, HarmonyOS system is much better than Android. If it was an old model many years ago, Android would have been stuck, but HarmonyOS still had the basic process, which must be praised. However, because of the sanctions imposed by American devils, Huawei has invested in research and development, which is really ugly. I hope Huawei can tide over the difficulties as soon as possible. Come on, Huawei. Although I have no money to support you, I support you mentally!

Apple didn’t work well at first. The users were mice. It took constant use, constant feedback and patching to make today’s Apple. I believe Huawei will eventually surpass Apple and look forward to it. I think I can experience the smoothness and stability of p60 equipped with HarmonyOS 3.1 system offline. I feel that it is as good as apple’s taste. I look forward to mate60 equipped with 4.0 system.

I hope that every update in HarmonyOS is a real user experience, not a fancy push. I also hope that Huawei products can freely download and uninstall all kinds of apps (including their own). I personally support Huawei. As a flagpole of our country, I still support it time and again. Some of them are system foundations, and there will be problems when uninstalling the system, and even if it is Apple’s, it will only be hidden and not displayed on the desktop.

Chopsticks Brothers’ new work "We Are the Sun" shows different brotherhood.

Following the divine comedy "Little Apple" which swept across the north and south of the river, the Chopsticks Brothers recently launched a new single "We Are the Sun" at the end of the year and the beginning of the year, sending blessings and hopes for the new year with the help of singing. This inspirational theme single with exciting lyrics and catchy melody is expected to follow old boys, Father and Little Apple.

Since their debut in 2007, Chopsticks Brothers have experienced many ups and downs on the road of musical dreams. No matter how difficult the situation is, they encourage each other and never give up. Just as Shawn, a chopsticks brother, once said in Weibo, "No matter how much pain you experience, a good friend will always be with you." Men say thank you directly and never affectedly, and all their words of thanks are integrated into this song and sung to each other. This is also the reason why this theme song is launched for a game with team interaction as the core gameplay, just for those two words: "brother". This time, it is different from the sad route of old boys and Father and the retro feelings of Little Apple. The Chopsticks Brothers chose the theme of inspiration and dreams as their creative theme, and Wang Terry personally wrote lyrics. The lively and powerful electronic rock style is full of excitement and writes inspirational positive energy in life, just as the lyrics sang, "We are the sun, without anyone’s light, life is a battlefield everywhere, and anyone can." "We are the Sun" has also officially become the theme song of the flight group of "National Aircraft War", and the "Chopsticks Brothers" made a special trip to shoot a theme poster for this purpose, leading the whole people to fight for the "dream" together. The singing of "Chopsticks Brothers" is full of the burning of youth and the full bloom of life, which brings a new hope and encouragement when the new year comes. Such a lively and exciting "We Are the Sun" with catchy melody, with the full interpretation of the creator of the Divine Comedy "Chopsticks Brothers", is also expected to capture the square dance again and set off a new wave of Divine Comedy.

On the road of dreams, they have also experienced silent cultivation and persistence, and experienced ups and downs and doubts. However, no matter what difficulties they experienced, "Chopsticks Brothers" always retained their initial intention to fight for their dreams, and responded to disputes with music and works. These experiences are also the emotional core of their creation "We Are the Sun". It is only because of empathy that the songs have more touching power. Today’s "Chopsticks Brothers" not only focus on the music field, but also successfully cross the border in the fields of director and performance. At present, the movie "Love Saint" starring Shawn partner NI YAN is about to be released, perhaps just like what is sung in this song, "Chopsticks Brothers" also carries their own dreams, constantly tries and challenges themselves, and brings new surprises again and again in more capacities such as director, actor and singer, so that the outside world can see a more multifaceted one.

Behind the frequent resignation of executives of new forces in building cars: due to losses or normal changes?

  Zhongxin Jingwei, December 17 (Sun Qingyang) Near the end of the year, all major car companies have entered the sprint stage, making every effort to achieve the sales and revenue targets. However, brands including Tucki, Ideality and Aouita have successively changed coaches or frequently transferred high-level personnel. As the end of the year approaches, why do the new forces of building cars frequently leave the company?

  The new forces of building cars are now leaving the company.

  On December 9th, it was reported that Li Pengcheng, assistant CEO of Xpeng Motors, had recently left his post. Xpeng Motors responded that Li Pengcheng resigned due to personal physical reasons. On the same day that Li Pengcheng was rumored to leave, Li Xiang, the founder of LI, issued an internal letter announcing that Shen Yanan, the co-founder, would resign. Since January 1, 2023, Shen Yanan will no longer serve as the president of the company. Ma Donghui, the chief engineer, will succeed Shen Yanan as the president of LI and join the board of directors, taking charge of the R&D and supply group as a whole, and Xie Yan, the senior vice president, will be the ideal CTO. Coincidentally, in recent days, there are many new power enterprises that have also experienced similar situations. After the release of the third quarterly report, Beiqi Blue Valley and Changan Automobile Aouita have undergone major personnel adjustments.

  "Substitution is to tap the potential internally, on the one hand, improve the supply chain and enhance the bargaining power for suppliers; On the other hand, reduce management and consumption costs and make enterprises break even. " Pan Helin, co-director and researcher of the Digital Economy and Financial Innovation Research Center of the International Joint Business School of Zhejiang University, believes that the new car-making forces have generally not got rid of the situation of increasing income without increasing profits, and many new car-making forces still have negative profit margins. For the new forces making cars, it is their goal to get positive cash flow and net profit in the future. At present, the sales of new car-making forces have reached a certain scale, and the scale effect has indeed reduced certain costs, but it is far from enough.

  Zhang Xiang, dean of the New Energy Automobile Technology Research Institute of Jiangxi New Energy Science and Technology Vocational College, said that at the end of the year, companies are generally required to conduct assessments. If the assessments fail, the executives will resign. If the assessment is really unqualified, the bonus incentives promised to executives before will not be available. Therefore, the end of the year is a time node for a company to assess its annual performance. In addition, the company also needs to make a new year’s work plan and hope to make adjustments to the management. These factors are superimposed, leading to the departure tide of senior executives. At present, many car companies hire professional managers to be executives. In a certain assessment period, those who fail the assessment will resign automatically.

  Can the new forces get out of the long-term loss dilemma?

  IDC’s latest report "Market Trend Forecast of New Energy Vehicles in China from 2022 to 2026" shows that the market size of new energy vehicles in China will reach 15.98 million vehicles in 2026, with a compound annual growth rate of 35.1%. It has always attracted various players such as new car-making forces, traditional car companies, technology companies and mobile phone manufacturers to join.

  However, many new forces have fallen into the situation of "selling one car and losing one". In the first three quarters of 2022, Weilai Automobile lost 8.6 billion yuan, and in the third quarter alone, it lost 4.1 billion yuan. Xpeng Motors followed closely, losing 6.8 billion yuan in the first three quarters; LI also lost 650 million yuan in the first half of this year.

  In the future, can the new forces get out of the long-term loss dilemma? Pan Helin believes that some car companies can, and the key is how to improve the bargaining power of the supply chain. The new forces of car-making need to extend from the downstream to the upstream. When the key parts are self-sufficient, the bargaining power will be improved, the cost of the new forces of car-making will be reduced, and the new car design will be more comfortable.

  Zhang Xiang said that only a few of the new brands in the head can finally make a profit, and the profit cycle is still very long. Comparing Tesla’s profit time, we will know that it took more than ten years to make a profit. "Tesla started early, when the industry market was still a blue ocean." Now, these new car-making forces are facing greater challenges than Tesla. In addition, traditional car companies like BYD, GAC and Volkswagen have already caught up. Therefore, it will take a long time for some new forces to get out of the long-term loss dilemma. (Zhongxin Jingwei APP)
