Glioblastoma multiforme (GBM) is a highly malignant brain tumor. Under normal physiological conditions, GBM uses glucose as the main energy source to support the rapid proliferation of tumor cells. In addition, other nutrients such as sugar, amino acids and fatty acids can also be used as energy sources for GBM. Epidemiological studies show that excessive intake of fructose is closely related to malignant progression of tumor. In mammalian cells, the fructose metabolic pathway is different from the glucose metabolic pathway at the initial stage. GLUT5 (encoded by SLC2A5 gene) is responsible for transporting fructose into cells, where fructose is phosphorylated by ketohexokinase and converted into fructose-1- phosphate, and then aldolase B splits one molecule of fructose-1- phosphate into one molecule of glyceraldehyde and one molecule of dihydroxyacetone phosphate, which are converted into glyceraldehyde-3- phosphate by phosphorylation and isomerization respectively.
In mammals, Integrate Stress Response (ISR) can be divided into endoplasmic reticulum stress, amino acid deficiency stress, virus infection stress and heme deficiency stress, which correspondingly activate four protein kinases-Perk, GCN2, PKR and HRI. Previous studies have shown that these four protein kinases can selectively activate the translation of transcription factor ATF4 by phosphorylating protein translation initiation factor eIF2α, and then ATF4 activates the expression of its downstream target gene to complete the cell stress response program.
On October 16th, the research team of Li Xinjian from the Institute of Biophysics, Chinese Academy of Sciences published a research paper entitled ATF4-dependent fruitolysis fuels growth of glioblastoma multiform online in Nature Communications. This study revealed that GBM activated cell ISR under the condition of glucose deficiency. By immunoprecipitation of high-throughput sequencing (ATF4 ChIP-Seq) against ATF4 chromatin, it was found that ATF4 could bind to the promoter region of two key proteins (GLUT5 and ALDOB) in fructose metabolism pathway and activate the expression of these two proteins. At the same time, destroying the DNA sequence of SLC2A5 and ALDOB promoter region combined with ATF4 by gene editing could effectively inhibit fructose metabolism induced by ISR. Furthermore, the functional study found that blocking ISR-induced fructose metabolism from gene level and small molecule inhibitor level can significantly inhibit the cell proliferation and clone formation ability of GBM under the condition that fructose (non-glucose) is the energy-supplying substance. In nude mice transplanted tumor model, it was found that ISR caused by glucose deficiency widely existed in GBM tissues, and blocking fructose metabolism induced by ISR could effectively delay the progress of GBM. The above research suggests that fructose is an alternative energy-supplying nutrient for GBM under glucose deficiency.And GBM patients should be wary of high fructose diet. Therefore, designing small molecular drugs to target fructose metabolism is a potential treatment for GBM.
The research work is supported by the National Natural Science Foundation of China, Chinese Academy of Sciences and national key R&D programs.

Fructose metabolism mediated by ATF4 promotes malignant progression of glioma. Under the condition of energy stress (glucose deficiency), protein kinases GCN2 and PERK selectively activate the translation of transcription factor ATF4 by phosphorylating protein translation initiation factor eIF2α, and ATF4 binds to the promoter regions of two key genes SLC2A5 and ALDOB in the fructose metabolism pathway and activates fructose metabolism induced by the expression of these two genes, thus providing energy sources for GBM cells with glucose deficiency and maintaining the malignant progress of tumors.
The high-energy poster of ＂The Mystery Case＂ and ＂Meng Chong Secret Service Team＂ was released.
1905 movie network news Adapted from the world classic Grimm’s Fairy Tales, an animated film co-directed by Wolfgang Lauenstein and Christoph Lauenstein, the award-winning directors of the 62nd Academy Awards, will be released nationwide on November 15th. On November 11th, the official released the poster of "Perfect Cooperation" with four leading actors, and the expressions of the agents on the screen seemed to reveal the vagaries of the road to adventure.
Don’t miss the adventure of pet days agents.
This poster of "Perfect Cooperation", which was officially exposed on November 11th, highlights the cute theme of the film and the adventurous nature of the agents through the funny "detective moments" of four fledgling agents. The most anticipated pet adventure animation in November is "Meng Chong Secret Service".
The poster of "Perfect Cooperation" shows the "seamless" cooperation among the four agents. With the help of his big body, Grey Donkey bends down and is willing to become the foundation of "Optimus Prime". The watchdog tried its best to lift the other two partners up; The cock sat on the head of the watchdog in a very funny posture, with a puzzled face; The cat, on the other hand, stepped on the rooster, unfolded the mysterious drawings, and lost in thought. Can the falling photos and the map of the poster background help Meng Chong agents solve the case smoothly? This answer will be found in the cinema on November 15!
Invincible contrast, cute pet, funny and high energy in the world
A pampered but adventurous cat, a graceful and indecisive rooster, a watchdog who hates human beings but yearns for freedom, and a gray donkey with a cheerful personality and dreams. Four different and harmonious characters formed a "detective" team, and also produced a wonderful chemical reaction!
The "secret life" of pets is well shown in the film. The cute pets who look "very clever" at ordinary times all have distinct personalities, and their common aspiration is to become heroes. The cute and exaggerated performance shows the extremely adventurous spirit of pets, and at the same time, it resonates with everyone and is impressed by the insightful and wonderful imagination of the creative team.
It is understood that Wolfgang Lauenstein and Christoph Lauenstein, directors of this film, are twin brothers.

The glory of more than one jiazi： a review of the development history of Mercedes-Benz E-Class
The style of the E350 convertible is different from that of similar models. It doesn’t have the obvious feeling of a sports car. On the contrary, it is elegant and calm from the inside out, which is very tasty. Developed on a C-class platform, it first took advantage of the BMW 3 Series and A5 convertible version because it was called "E Class". In addition, its appearance has indeed made up for the current vacancy of Mercedes-Benz in sub-models.
It is also a Mercedes-Benz E-class, but this time the E350 convertible version has brought us different feelings. The chassis from the C-class makes it more compact. The extremely balanced handling and the stability of the chassis are surprising, and I don’t even think it is a rear-wheel drive. Of course, there are also many places that embody luxury, and coupled with the soft-top convertible that is fashionable, it is not too much to say that it is a toy for the rich.
This is a car that combines quality and romance, and its driving style continues the steady style of Mercedes-Benz. You will be surprised to find that although this car belongs to a personalized model, it is actually suitable for all kinds of people aged 18-80. This is the characteristic of Mercedes-Benz, which is suitable for anyone who has money.
The frequent occurrence of extreme words ＂Putin assassination theory＂ highlights the hostility between the United States and Russia
Profile photo: On October 18, in Moscow, the Russian capital, Russian President Vladimir Putin listened to questions from the public during the program. Xinhua news agency
Just as Russia celebrated Putin’s choice of successor, the American think tank published a report containing "Putin may be assassinated in 2008", which caused strong repercussions in Russia. American experts rushed to clarify and criticized the Russian media for "exaggerating Putin’s assassination" as "irresponsible". Since the beginning of this year, the tension between the United States and Russia has escalated rapidly. Putin has repeatedly publicly criticized the United States, and the American media has also selected extreme words such as "greed" and "dictator" to be blamed on Putin. The British "Economist" said that "the hostility between Russia and the United States is reaching an unprecedented level after the end of the Cold War, and the anti-American propaganda at the end of the Soviet Union is not as emotional and real as it is today." On 15th, Russian senior generals’ remarks that "missiles may automatically strike back at American missiles" were interpreted by experts as "a nuclear war will happen at any time" between the United States and Russia. With the presidential elections in both countries next year, the hostility between the two sides is likely to escalate further.
"Putin’s assassination" triggered a fierce confrontation
On December 13th, Russia’s Kommersant reported the report "Russia’s Future Options" just published by the Center for Strategic and International Studies, an American think tank, with the title "Russia and the world will be shocked by Putin’s assassination". In the report, Kaczynski, a famous American expert on Russia, predicted that Putin might be assassinated after attending the Orthodox Christmas ceremony on January 7 next year, and Russia would fall into chaos. As Pu Jing has just chosen a successor and was invited to be the next prime minister of the government, Russians are full of longing for the future. This somewhat "killing scenery" prediction was quickly concerned by the Russian News Agency, Morning Post and other media.
A day later, Kaczynski publicly criticized Kommersant for distorting the original intention of the report, saying that Kommersant’s report that he predicted that Putin would be assassinated was ridiculous. Kaczynski said that in his report, he described three possible plans for Russia’s development: the first plan is also the most likely, that is, Russia will achieve steady development; The second scheme calls attention to the danger that a country’s political life depends too much on one person, and the assumption of Putin’s assassination is based on this; The third scheme predicts how the situation in Russia will develop once the oil price drops. He said that Kommersant was irresponsible because it published one of the hypothetical schemes. Kaczynski told the Russian News Agency: "I have been studying Russia all my life and have been to Russia many times. I also have many friends in Russia. And this article puts me in danger of losing my reputation. Some Russian politicians will think that this is an embarrassment to Russia, the Russian people and the Russian president. "
In this regard, the editor-in-chief of Kommersant retorted: "His statement is despicable and absurd. I read the Russian and English versions of this article, and we don’t admit that it is a conscious distortion of the basic views of the report. " "Kommersant" said in Kaczynski’s rebuttal news on the 14th that the report never made it clear that these assumptions were only theoretical.
On the 16th, on YouTube, the most famous video website in America, various comments were full of gunpowder. Some people say that "of course, those animals like to see Putin die", while others say that "Kommersant reporters are still exhibiting their ubiquitous Soviet-style propaganda". A netizen named "WIN096" said, "In Russia, Kommersant has a reputation as a pro-Western newspaper, so don’t underestimate this report. Putin has put Russia back on its feet. Obviously, Americans don’t like this. They can’t wait for a Russia without Putin. Assassination? Has the CIA ever assassinated foreign leaders? Of course, they have. They have done it many times before. It is not surprising that the assassination of Putin becomes a fact. "
"Missile automatic counterattack" becomes "nuclear war"
On the 16th, Professor Koskov from the Department of Russian and International Politics of Moscow University said that the incident profoundly showed that there was always misunderstanding in the communication channel between Russia and the United States, and there was always subconscious prejudice between the two sides, so they often could not interpret each other with a correct attitude. Koskov believes that the reason why the Russian media is so sensitive is because Russia itself lacks a sense of security, completely distrusts the United States, and the hostility between the two sides has increased.
In June 2001, after the first summit of Bush Putin, Bush said that Putin was "very frank and trustworthy", but since then, the two sides have increasingly criticized and questioned each other. At the Munich security conference earlier this year, Putin publicly criticized the unilateralism of the United States, and the western media said that "Russian leaders threatened to target Europe with nuclear bombs for the first time after the Cold War." Last month, Putin denounced the domestic opposition as a "running dog of the West", which shocked the West even more. The British "Economist" article entitled "Longing for the Cold War" on the 14th said that Russia’s hostility towards the United States is reaching an unprecedented level after the end of the Cold War.
On 15th, Baluyevsky, Chief of General Staff of Russian Armed Forces, severely criticized the US plan to deploy an anti-missile system in Eastern Europe. He said that the anti-missile missile launched by the United States may be mistaken by the Russian defense system as an intercontinental ballistic missile aimed at Russia, and thus it will be hit back, because the missile early warning systems of the United States and Russia are now automatic. The Russian "Viewpoint" borrowed the analysis of experts and believed that "the prospect of nuclear war between Russia and the United States is becoming more and more obvious." According to reports, the United States is provoking Iran or other Islamic countries to launch a nuclear attack on it. When a missile aimed at the United States is launched, its anti-missile system in Eastern Europe will play a role. When anti-missile missiles fly over Russia, they will be regarded as attack missiles, which will trigger Russia’s missile automatic early warning system to launch missiles at the United States, and the United States, which has advanced anti-missile systems and formal excuses, will begin to carry out nuclear strikes, resulting in both losses. The article also emphasizes that "this is not a plot in the novel, but a realistic military threat, which may happen at any time".
In recent years, Russian polling agencies have conducted surveys on "Who is Russia’s enemy" more than once, among which the United States often occupies the top spot. Kommersant analyzed: "When the United States criticized and suppressed Russia most severely, it was also the time when the Russian people’s anti-American sentiment was at its peak." Ella, the American coordinator of the NATO-Russia Council, said, "Since 2003, the Russian government has always portrayed the West as Russia’s sworn enemy and cultivated a feeling against the West." Russia’s subsequent oil power exacerbated the current anti-western sentiment.
The United States openly discusses whether Russia is an enemy.
An article in American Conservatives magazine in March this year said that after the "9.11" incident and the Iraq war, some people thought that America’s hostility towards Russia and its anti-Russian global geopolitical agenda would basically disappear. But this is not the case. On the contrary, the hostility of the Bush administration, the two parties in Congress and the American media towards Russia has only increased. The report believes that part of the reason is the Cold War. The Soviet Union was once the number one enemy of the United States, and too many Westerners did not distinguish between the Soviet Union and Russia. Also due to the influence of the cold war, lobbying groups from Poland and other places have hatred for their country’s submission to the Soviet Union. Many elites in Washington are also particularly hostile to Russia, "because long before the Iraq war broke out, Russia betrayed the idea of freedom and democracy cherished by the United States to set an example for other countries."
In the United States, there are more and more occasions to link "Russia" with "the enemy". The Middle East Times said that an editorial in the Wall Street Journal in November publicly suggested that "it’s time to start thinking again that Russia is an enemy". In October this year, six Russian experts took part in a discussion in new york, the theme of which was "Is Russia becoming our enemy again?" According to the pre-meeting survey, 41% of the audience thought yes, while 23% thought no.
Recently, due to dissatisfaction with the Russian Duma election and Putin, the US criticism of Russia has greatly escalated. Although American officials are cautious, the media does not hesitate to use extreme words. The New York Times published an editorial before the election of the Russian State Duma, attacking Putin’s "greed for power", saying that the election was neither free nor fair. George, a senior researcher at the American Council on Foreign Relations, said that "we have finally seen through his soul", and Washington post also said that "Russia is stepping on the threshold of restoring a one-party dictatorship similar to that of the Soviet Union". The hostility between the two sides is obviously not easy to disappear. The Christian Science Monitor reported on the 14th that although the world began to get used to the new name Medvedev, it should be realized that Putin, the familiar person behind him, will continue to face the challenge of confident Russia.

The first plenary session of the 19th Academician Conference of China Academy of Sciences was held.
CCTV News:The 19th Academician Conference of China Academy of Sciences held its first plenary meeting in Jingxi Hotel on the afternoon of May 28th. Bai Chunli, President of China Academy of Sciences and Executive Chairman of the Presidium of the Faculty, made a work report entitled "Deeply study and implement the spirit of the 19th Party Congress and strive for the great cause of Socialism with Chinese characteristics in the new era" on behalf of the Presidium of the 8th Faculty.
This academician conference is a scientific and technological grand meeting held at an important moment when the whole country is thoroughly studying and implementing the spirit of the 19 th CPC National Congress. The main tasks of the congress are to thoroughly study and implement the spirit of the 19th National Congress of the Communist Party of China, take Socialism with Chinese characteristics Thought of the Supreme Leader in the new era as the guide, focus on the development trend of the world’s science and technology frontier, focus on the strategic needs of national innovation and development, actively play the role of innovation as the first driving force and talent as the first resource, concentrate on wisdom, forge ahead, and strive to accelerate the construction of an innovative country and a world science and technology power and win the great victory of Socialism with Chinese characteristics in the new era.
Bai Chunli pointed out that the important speech of the Supreme Leader General Secretary at the opening meeting this morning stood in a new historical position, systematically summarized the great practice and historical achievements of China’s scientific and technological development since the 18th National Congress of the Communist Party of China, profoundly expounded the mission and task of China’s scientific and technological development in the new era, and emphasized that "China must vigorously develop science and technology and strive to become a major scientific center and an innovative highland in the world if it wants to be strong and rejuvenated". It is clearly stated that efforts should be made to support the construction of a modern economic system, enhance the ability of independent innovation, stimulate the vitality of innovation, promote the building of a community of human destiny, and consolidate the talent base for innovation and development. In his speech, the General Secretary also fully affirmed the important contributions made by the vast number of scientific and technological workers, including academicians, in realizing historic, holistic and structural major changes in China’s scientific and technological undertakings. He hoped that we would "aim at the world’s scientific and technological frontier, lead the direction of scientific and technological development, shoulder the heavy responsibility entrusted by history, and bravely be the vanguard of scientific and technological innovation in the new era", and put forward clear requirements for the two academies to play the role of the highest academic institutions and national high-end think tanks. The general secretary’s important speech is profound in thought, rich in content and profound in emotion, which is the fundamental follow-up of scientific and technological innovation in the new era and also points out the direction for us to do a good job in the department. We should thoroughly study and understand it, and conscientiously implement it in all the work of the department.
When reviewing the work in the past two years, Bai Chunli pointed out that the past two years were two years of great historical significance in the development process of the party and the country, and also two years in which China’s scientific and technological innovation developed rapidly and the construction of an innovative country achieved fruitful results; It is a two-year period in which China Academy of Sciences has carried out the "First Action" plan in depth, and major innovations have emerged continuously. It is also a two-year period in which China Academy of Sciences has continuously deepened the reform of the academician system and continuously strengthened the team of academicians and self-construction. In the past two years, the Presidium of the Chinese Academy of Sciences has United and led all academicians, accurately grasped the functional orientation of the Chinese Academy of Sciences, worked hard, and made remarkable progress and achievements in improving and perfecting the academician system, promoting the construction of national high-level scientific and technological think tanks, giving play to the leading role of academics, disseminating scientific knowledge, building scientific culture and strengthening international exchanges and cooperation.
Bai Chunli emphasized that the Presidium of the Faculty conscientiously implemented the State Council’s "Proposal on Improving and Perfecting the Academician System", actively consolidated the achievements on the basis of a good start in the previous period, made steady and in-depth progress, and completed the overall task. In 2017, 61 academicians were newly elected, with an average age of 54, and 92% of them were under 60. The problem of rejuvenation of academicians has been solved from the source. The special recommendation mechanism for emerging and interdisciplinary disciplines, national defense and national security was further improved, and the discipline structure of the academician group was further optimized. The number of newly elected foreign academicians is the highest over the years, and the nationality distribution of foreign academicians has been further optimized. In addition, the academic department actively cooperated with the implementation of the academician retirement system, conducted research and analysis on the issues that need to be concerned and the possible impact of the implementation of the academician retirement system from the requirements of improving and perfecting the academician system and the current situation of the academician team, and actively put forward policy suggestions to the relevant departments, which received great attention from the party and the state. Recently, the State Council has issued the Notice on Issues Related to Doing a Good Job in Academician Retirement, which clearly and steadily promoted the academician retirement work, and some issues that academicians are generally concerned about have been well implemented, which fully reflects the party and the state.
Bai Chunli pointed out that the department conscientiously implemented the requirements of the Supreme Leader General Secretary for the Chinese Academy of Sciences to "take the lead in building a national high-level science and technology think tank" and solidly promoted the construction of science and technology think tanks. In the past two years, the department has deployed 96 major consulting projects, and the standing committees have organized consulting research, completed 46 consulting reports and 21 suggestions from academicians, and received important instructions from central leading comrades for nearly 100 times, which provided scientific basis for the macro-decision-making of the party and the state and important support for the work of relevant departments. In the past two years, the reform of the system and mechanism has been further deepened, and the Council of Science and Technology Think Tank of China Academy of Sciences has been established as the leading decision-making body for the construction of science and technology think tanks, which has further strengthened resource integration and overall coordination; The docking and cooperation mechanism with relevant state ministries and policy research institutions has been strengthened, so that the construction of science and technology think tanks can serve the party and state decision-making more pragmatically and efficiently.
Bai Chunli emphasized that the department has long adhered to the concept of high-level, leading and exploratory, taking the strategic study of discipline development as the main line and taking academic journals, academic conferences and scientific and technological awards as the platform to further promote the systematization of academic leading work. Through independent deployment and joint deployment with the National Natural Science Foundation of China, the research on discipline development strategy has been continuously carried out. The research projects basically cover the main disciplines in China, which has played an important role in optimizing the layout of science and technology, leading the development direction of science and technology and improving the level of scientific research and education. At the same time, the academic vitality and influence of China Science and Science Bulletin have made a breakthrough. A multi-level and high-level academic exchange system consisting of annual academic conferences of academic departments, frontier forums of science and technology, small high-end forums and academic forums of various academic departments has initially taken shape; The quality and level of the Tan Kah Kee Science Award and the Youth Award have been continuously improved, and the authority, professionalism and fairness have also been better reflected.
Bai Chunli pointed out that the majority of academicians regard the dissemination of scientific knowledge, scientific methods and scientific spirit as their social responsibility, and strive to build the department into a scientific hall that holds high the banner of science and carries forward advanced culture. In the past two years, the Department has organized academicians to go deep into universities and research institutes to give lectures on "Scientific Morality and the Construction of Study Style", organized a series of activities to learn from Academician Wing Gen Lou, started the special work of oral stories of academicians, and planned and organized the publicity activities on the theme of "A Hundred Years of Scientific Life", striving to give full play to the role of academicians as models of virtue. The department pays attention to developing science education and popular science work for different needs. Facing leading cadres, mainly through the training of "scientific thinking and decision-making", support the improvement of scientific ruling ability; Facing the public, it mainly focuses on hot issues of general concern to the society and issues authoritative voices in a timely manner. In the past two years, the department has organized more than 360 reports by academicians and experts; Successfully cooperated with CCTV to shoot popular science feature films such as Revealing AIDS and Revealing Antibiotics. The scientific and authoritative science popularization work of the department has been widely recognized and praised by the society.
Bai Chunli emphasized that strengthening international scientific and technological exchanges and cooperation, enhancing China’s influence in international scientific and technological circles and promoting scientific and technological diplomacy are the important missions of the department. Over the past two years, more and more academicians have held important positions in international scientific and technological organizations, and many academicians of China Academy of Sciences have been elected as academicians of academy of sciences for the developing world and other national academies or engineering institutes. The international grand science program initiated by the consulting project of the department has had a significant impact. For example, the Digital Silk Road International Science Program (DBAR) has begun to make outstanding contributions to serving the global sustainable development and the construction of the Belt and Road Initiative. The department founded the international Yanqi Lake Conference. The theme of the first conference was "Microbial Oceanography — Land and sea as a whole on carbon sinks ",the relevant achievements directly provided strong support for the writing and discussion of the Intergovernmental Panel on Climate Change (IPCC) marine report, and greatly strengthened China’s right to speak in the field of marine ecosystems.
Do not forget the initial intention of serving the country through science and technology, and keep in mind the mission of strengthening the country through science and technology. Bai Chunli pointed out that science and technology have always played an important role in the process of "standing up", "getting rich" and "getting strong" in modern China. Facing the new situation and new challenges in the development of science and technology in the new era, we should clearly understand the historical position and role mission of the department. At present, the ability of scientific and technological innovation does not meet the requirements of building a modern power, the level of scientific and technological innovation does not meet the goal of building a world-class scientific and technological power, the quality and efficiency of scientific and technological achievements do not meet the expectations of the country and people, the level and structure of scientific and technological teams do not meet the requirements of scientific and technological innovation development, and the system, mechanism and culture do not meet the requirements of scientific and technological innovation in the new era. Science and technology should support the country’s prosperity and rejuvenation, face up to these challenges and solve these problems, which is the main task of China’s scientific and technological circles at present and in the future, the focal point and breakthrough point for China Academy of Sciences to implement the "take the lead" plan and accelerate the reform and innovation, and also the important content of the work of the department. I hope that the academicians will dare to take the lead, set an example, be determined to innovate, and make suggestions and suggestions. In solving these major problems, they will be brave to be the leaders of science and technology, the promoters of deepening reform, the pioneers of innovation and development, and the builders of science and culture, so that the academician group will truly become the leader and vanguard of China’s construction of an innovative country and a world science and technology power.
Regarding the consideration of the next work of the department, Bai Chunli emphasized that the work of the department should be considered and coordinated under the background of the development of the cause of the party and the country, the strategy of innovation-driven development and the construction of an innovative country. It is necessary to further enhance the sense of historical responsibility and the sense of urgency of the times, keep a clear head, adhere to the problem-oriented, compare advantages, find gaps, find shortcomings and make up for shortcomings, and creatively do a good job in the work of the department with new actions and a new look. In particular, it is necessary to give full play to the exemplary role of academicians as leading talents in science and technology, promote the close integration of science and technology with economy, and better serve the construction of a socialist modern and powerful country; It is necessary to give full play to the academic leading role of the academic department as the highest academic institution in the country, observe the general trend, seek strategy and clear direction, and lead and drive China’s construction of a world science and technology power; It is necessary to give full play to the role of the department as the highest scientific and technological advisory body in the country, speed up the construction of high-level scientific and technological think tanks, and provide more high-quality decision-making basis for the party and the country; It is necessary to give full play to the main role of the academician group and further strengthen the self-construction of the department.
Bai Chunli pointed out that in his important speech, the General Secretary of the Supreme Leader clearly stated that he hoped that we would carry forward the glorious tradition of serving the country scientifically, pursue the truth, bravely climb the peak of the scientific spirit, be brave in innovation, be rigorous and realistic in academic atmosphere, consciously integrate our personal ideals into the great cause of national development, pursue diligently at the forefront of science, and constantly make breakthroughs in major scientific and technological fields; I hope that we care about and care for young talents, be good leaders in promoting post-school students, take discovering, cultivating and promoting young talents as an important responsibility, and provide more opportunities and a bigger stage for young talents to display their talents. We should bear in mind the entrustment and live up to the ardent hopes of the party, the country and the people.
At this meeting of all academicians, Bai Chunli also gave lectures to Professor Xiaodong Wang from Beijing Institute of Life Sciences, Professor Markku Tapio Kulmala from Helsinki University, Finland, Professor Paul Nurse from Francis Crick Institute in Britain, Professor Atta-ur Rahman from Karachi University, Pakistan, and the Ministry of Education and Science of the Russian Federation/ Professor Valery Bondur from the Institute of Space Observation Science of the Russian Academy of Sciences, Professor Jerzy Duszynski from the Polish Academy of Sciences, Professor Toshio Fukuda from Beijing Institute of Technology, Professor John Edward Hopcroft from Cornell University, Professor Yonggang Huang from Northwestern University, Professor Zhixun Shen from Stanford University, USA, Thirteen foreign academicians newly elected in recent years, including Professor James Fraser Stoddart of Northwestern University, Professor Xiao-Fan Wang of Duke University and Professor Xiaoliang Xie of Harvard University, awarded academicians’ certificates and badges.

The first batch of domestic durian listed industry insiders： the price will not fall in the short term.
Yang Jinying, a journalist with extreme eyes.
"Click — —” With the crisp crackling sound, recently, in the durian planting base of Yucai Ecological Zone in Sanya, Hainan, more than 1,000 mu of durian naturally fell off after ripening on the tree, and the domestic durian ushered in the first listing.
On July 26th, the relevant person in charge of the agricultural company involved in the large-scale planting of durian in Hainan introduced to Jimu journalist that the price of this batch of mature durian is 60 yuan per catty, which will be sold to offline tasting shops in first-tier cities for consumers to "try early" in addition to the local market in Hainan. Compared with imported durian, the quality of domestic durian is superior. Considering the planting cost and other factors, the price will not drop in the short term, but it will affect the price of imported durian.
Durian ushered in harvest in Hainan (Source: Xinhua News Agency)
Domestic durian tastes better.
As a tropical fruit, durian has very strict growth conditions, and there are few areas suitable for planting in China. According to relevant experts, in fact, durian was introduced and planted in Hainan as early as the 1950s, but at that time, the number of introduced seedlings was very small and the survival rate was extremely low, so the industry thought that China was not suitable for planting durian.
Durian for domestic consumption mainly depends on imports. According to the data in 2022, the total number of imported durians is as high as 825,000 tons, of which 780,000 tons are imported from Thailand, and the other 45,000 tons are imported from Southeast Asian countries such as Malaysia and Vietnam.
In order to break the curse that "durian can’t be planted in China", in the first decade of the 21st century, Hainan people continued to explore local durian cultivation. In recent years, durian trees planted in front of and behind local residents’ houses showed individual results.
In 2019, Hongxiang Agricultural Group Co., Ltd. began to open a large-scale durian planting plate in Hainan. In the past four years, the company has laid out 12,000 mu of durian planting area in Hainan, including 7,000 mu in Sanya Yucai Ecological Zone, of which 1,400 mu is expected to be listed before the end of July.
What are the advantages of domestic durian compared with imported durian? Du Baizhong, general manager of Hongxiang Agriculture, said that the imported durian is destined to be picked when it is only 78% mature or even 6% mature, and then it will enter the domestic market after artificial ripening; On the other hand, frozen durian is transported by cold chain, and quick freezing with liquid nitrogen will destroy its fruit aroma. In any case, the taste of imported durian is easily damaged, and it is difficult to guarantee the quality by artificial ripening. Buying durian is often like "opening a blind box".
In contrast, domestic durian can fall naturally after "ripening on the tree", and it has more advantages in quality. Du Baizhong said, "The smell of ripe durian is not strong, and it is dried with yellow meat and tastes more delicious."

The price will not fall in the short term.
The first batch of domestic durians will be on the market soon, and the question that durian lovers are most concerned about is, "Can this be achieved ‘ Durian Freedom ’ " . Ms. Mai, a citizen of Guangzhou, told the reporter that she had eaten durian eight or nine times this year, and the quality was different, but she felt that the price fluctuated greatly and it was much more expensive than in previous years.
However, relevant experts said in an interview with the media that the domestic durian has not yet formed a large-scale commercial planting, and the price will not be significantly lowered in the short term. The domestic demand for durian will still rely on a large number of imports for a long time.
Du Baizhong expressed similar opinions to reporters. He introduced that the first batch of domestic durians to be listed this year has a total of dozens of tons, and the cultivation process is very difficult.
"When planting was first developed, the survival rate of durian trees was very low." Du Baizhong said, "We consulted a large number of experts and cooperated with relevant agricultural research institutions in Hainan Province. Until 2021, the technology became mature and the durian survival rate increased from about 60% to 97%-98%."
Therefore, considering the planting cost and the limited output of the first batch, the price of this batch of mature durian is 60 yuan per catty, which will be sold to offline tasting shops in first-tier cities for consumers to "taste early" in addition to the local market in Hainan. Du Baizhong introduced that this pricing is slightly lower than the high-quality durian that is 85% cooked in Thailand and transported to China, but the quality of domestic durian is far better than that of imported durian.
However, Du Baizhong also said that by next year, the domestic durian production will be several times, and the price should be reduced. At the same time, with the expansion of large-scale planting of high-quality durian in China, it is believed that the price of imported durian can be "knocked down".
The fate of the big party is in harmony with the world.
The great changes in the world today, which have never happened in a century, are accelerating their evolution. The world is multipolar and economic globalization is undergoing profound changes, and human society is once again facing the historical juncture of where to go. As the largest political party in the world, how can the Communist Party of China (CPC) promote human progress with a global vision, a world mind and a big country?
"Taking history as a mirror and creating the future, we must constantly promote the building of a community of human destiny." General Secretary of the Supreme Leader gave a clear answer at the celebration of the centenary of the founding of the Communist Party of China (CPC).
Man is a whole and the earth is a home. In the face of common challenges, no one or any country can be immune to it, and mankind can only work together and live in harmony.
Reflecting the reality with history and looking into the future from a distance, the Communist Party of China (CPC) pondered the profound proposition of national rejuvenation and human progress in a broad space-time dimension, and engraved the distinctive logo of profound interaction with the outside world with the "community of human destiny".
和平、和睦、和谐是中华民族5000多年来一直追求和传承的理念，中华民族的血液中没有侵略他人、称王称霸的基因。近代中国饱受的苦难令中华民族深切懂得世界和平稳定对于国家发展的重要意义。
求同存异，广交天下朋友，中国共产党一直以开放的眼光、开阔的胸怀面向世界。
早在抗战时期，中国共产党曾接待了一批批访问延安的外国新闻工作者，并与他们结下了深厚的友谊。中国革命的真实信息通过斯诺、斯特朗、史沫特莱等人的报道走向国际社会。世界对中国革命、中国共产党人和中国人民有了新认识。
1953年12月，中国首次提出和平共处五项原则。这不仅成为我国对外政策的基石，也逐渐在国际社会中被普遍接受，为推动建立公正合理的新型国际关系作出了历史性贡献。
1954年4月，新中国首次以五大国之一的身份参加日内瓦会议，促使会议达成恢复印度支那和平的协议，法国从越南、老挝、柬埔寨撤军，并确认三国的民族独立地位，使亚洲局势和国际局势进一步缓和。
20世纪70年代初，我国国际战略和外交政策作出重大调整，提出“三个世界”划分的战略思想，明确中国属于第三世界，反对霸权主义。
……
The Communist Party of China (CPC) has always adhered to the path of peaceful development, joined hands with all progressive forces in the world, and adhered to the common destiny of the people of China and the people of other countries in the world.
“‘ Belt and Road ’ It’s sunshine avenue where everyone goes hand in hand, not a private path of one party. All interested countries can join in and participate, cooperate and benefit together. " At the opening ceremony of the 2021 annual meeting of Boao Forum for Asia, the keynote speech delivered by the top leader won warm applause from the scene.
According to the analysis and prediction of the World Bank report, by 2030, the joint construction of the Belt and Road Initiative is expected to help 7.6 million people around the world get rid of extreme poverty and 32 million people get rid of moderate poverty.
In the face of the global spread of the epidemic, China has provided more than 300 billion masks, 3.7 billion protective clothing and 4.8 billion human test kits to more than 200 countries and regions, and has also provided more than 600 million doses of Covid-19 vaccine. China has continuously made important contributions to the global fight against epidemic diseases.
"China will adhere to the belief of openness, cooperation, unity and win-win, unswervingly expand its opening up in an all-round way, and will more efficiently realize the interconnection of internal and external markets and the sharing of factor resources, making the China market a world market, a shared market and a market for everyone." In November, 2020, when the COVID-19 epidemic ravaged the whole world and the world economy entered the cold autumn, the Supreme Leader declared China’s proposition to the world at the opening ceremony of the Third China International Import Expo.
Recently, the economic data released by the National Bureau of Statistics showed that in the first half of this year, China actually used 607.84 billion yuan of foreign capital, up 28.7% year-on-year and 27.1% compared with the same period in 2019.
China is favored by international capital, not only because of the large scale of China market, but also because China, under the leadership of the Communist Party of China, is coping with the new development opportunities brought about by the great changes.
"Provide new opportunities for the world with the new development of China." At the celebration of the centenary of the founding of the Communist Party of China (CPC), the Supreme Leader General Secretary made a solemn promise to the world.
In midsummer July, Pujiang surges. The latest "Opinions of the Central Committee of the Communist Party of China and the State Council on Supporting High-level Reform and Opening-up in Pudong New Area and Building a Leading Area of Socialist Modernization" indicates that Pudong New Area will become a pioneer of higher-level reform and opening-up in China. China welcomes all parties to share the great opportunities in the China market with practical actions.
The people of China are people who advocate justice and are not afraid of violence, and the Chinese nation is a nation with strong national pride and self-confidence.
In the long history of a hundred years, the Communist Party of China (CPC) led the people of China to overthrow the three mountains of imperialism, feudalism and bureaucratic capitalism, and to overcome the subversion and armed provocation of imperialism and hegemonism. No matter how the times develop, we must sharpen the national character of not being afraid of violence and resisting power.
The people of China don’t make trouble or fear anything. In the face of any difficulties and risks, their legs and stomachs will not shake and their waist will not bend. The Chinese nation cannot be frightened or crushed.
The wheel of history is rolling forward. At the celebration of the centenary of the founding of the Communist Party of China (CPC), General Secretary of the Supreme Leader once again solemnly declared the Communist Party of China (CPC)’s value concept: "Insist on cooperation, no confrontation, openness, no closure, mutual benefit and win-win, no zero-sum game, oppose hegemonism and power politics, and push the wheel of history towards a bright goal!"
The core idea of the current international system and international order is multilateralism. If multilateralism is practiced better, the common problems facing mankind will be solved better. International rules should be recognized by all countries in the world, and should not be formulated by a few people. Cooperation between countries should aim at serving all mankind, and should not seek world hegemony through clique politics.
The world is a highway.
"Everything we do is for the happiness of the people, for the rejuvenation of the nation, and for the great harmony of the world." General Secretary of the Supreme Leader pointed out that China has always been a builder of world peace, a contributor to global development and a defender of the international order.
The Communist Party of China (CPC) stands on the right side of history and on the side of human progress, and will surely make new and greater contributions to building a community of human destiny and a better world!

Take-away lunch boxes that are difficult to recycle： biodegradable and recyclable, no one cares.
At 1: 00 pm on September 1, there were still food delivery staff wearing various overalls in the stairwell of Jinlong Building "flying" in the corridor. A delivery man took six takeaways in one hand and waited by the elevator. He told reporters that his site delivered about 800 takeaways a day on average, and if it was raining and other bad weather, the delivery volume exceeded 1,000.
Correspondingly-a large number of fast food boxes are thrown into the garbage every day. The reporter saw in the unsealed garbage bin that the takeaway boxes were scattered and piled up, and some had more than half a bowl of soup left. "On weekdays, an average of 17 or 8 cars of garbage are collected a day, and each car is about 30 bags of takeaway garbage."
According to the statistics of Ai Media Consulting, a third-party research institution, 256 million takeaways were produced every day in 2016, including at least 256 million lunch boxes and plastic bags, which will take at least 470 years to degrade after use. Besides incineration, according to statistics, about 8 million tons of plastics are dumped into the sea every year.
"Degradable" lunch boxes will also pollute the environment.
"1000 in 55 yuan, wholesale degradable lunch boxes." "Biodegradable plastics are non-toxic and harmless." In lunch box wholesale markets and online stores, such word descriptions can be seen everywhere.
On Taobao, the reporter saw some disposable foamed lunch boxes with the words "degradation" clearly written on them. A lunch box supplier who settled in Tmall told reporters that their sales volume is calculated by trucks, and they sell an average of 3,000 trucks a year, with 200 boxes in each car and 300 sets in each box, which can sell 180 million sets a year.
Because they are "degradable", most people think that these plastics can eventually be degraded in the environment, which is green and harmless, and there is little psychological burden when they are discarded. But in fact? Experts say that biodegradable plastics will not degrade in the natural environment, but will cause lasting pollution to the environment, especially the marine environment. Therefore, the widespread use of products labeled as "biodegradable" will not significantly reduce the amount of garbage entering the ocean, or reduce the physical and chemical risks brought by plastics to the marine environment.
"Many things called biodegradable plastics do meet the standards set by some international institutions, but this only means that they can degrade at certain high temperatures." Han Shuo, a master of materials science at Zhengzhou University and editor of Materials+WeChat in WeChat official account, said. The most commonly used plastics, such as polyethylene, polypropylene and polyvinyl chloride, are not biodegradable in the ocean. It is almost impossible to achieve the specific conditions required for the degradation of some biodegradable polymers in the marine environment. For example, these polymers need to be treated at a high temperature above 50℃ for a long time before they decompose in industrial compost. There are a few very special plastics that do miraculously degrade, such as oxygen-degradable plastics, but these plastics have few uses and are more expensive.
In particular, Han Shuo pointed out that some surveys found that the decomposition of oxygen-degradable plastics in the marine environment is quite slow, which may take as long as five years. Moreover, the broken oxygen-degraded plastics continue to pose a threat to the marine ecosystem, and the resulting microplastics particles will be absorbed by marine organisms, resulting in the transport of harmful microorganisms, pathogens and algae.
In response to the quality monitoring of lunch boxes, the reporter learned that there is no standard for the specific ingredients of takeaway lunch boxes at present, and the personnel of relevant departments said that it is "non-toxic and harmless, as long as it meets food safety standards".
Hungry? The customer service staff of the takeaway platform told the reporter that the packaging of the takeaway platform is currently the responsibility of the merchants themselves, and the platform has no special requirements for the material and quality of the lunch boxes of the settled merchants. "Lunch boxes are sold by merchants to customers, and they are all charged and provided by the merchants themselves."
A Meituan takeaway rider said that the platform has no requirements for the environmental protection of lunch boxes, but "it must not contain harmful substances". For packaging, the platform requires that there should be no leakage, nor can it directly contain food in plastic bags.
"Recyclable" lunch boxes are mostly reduced to domestic garbage.
At present, there are mainly four kinds of take-away lunch boxes on the market, namely PS (polystyrene) packaging boxes, PP (polypropylene) packaging boxes, paper packaging boxes and degradable lunch boxes made of natural straw pulp or corn starch.
The reporter visited more than 10 merchants in the city and found that all the lunch boxes used by take-away merchants were purchased by online and wholesalers, and the material was mainly PP5 (polypropylene). The lunch box provided by a braised chicken rice merchant shows that the service temperature is "20℃-100℃", and the words "PP5", "QS" and "microwave oven permission" are also marked on it, and some merchants’ lunch boxes are also marked with the triangle symbol of "recyclable".
The owner of a Lamian Noodles in Lanzhou said that he didn’t know whether the lunch box was environmentally friendly, but he could guarantee that it was non-toxic and harmless. "This kind of lunch box is basically used for take-out in the market now, but to be on the safe side, we still remind customers to use it once and do not heat it." According to the boss, lunch boxes are purchased from the wholesale market, the price is one in 0.5 yuan, and the daily usage is about 50.
On take-away platforms such as Hungry, Meituan, etc., consumers will display the cost of lunch boxes when ordering food. Generally, according to the ordering quantity and usage, a lunch box is 1 yuan.
It is understood that all qualified PP5 lunch boxes have "QS" and number on them, which is equivalent to the product ID card and is also issued by the AQSIQ. This kind of product has undergone strict quality audit, that is, its raw materials, production environment and production technology, including the health requirements of personnel, are strictly regulated.
Marked with a triangle symbol, indicating that this material can be recycled. However, the reporter interviewed relevant departments and learned that at present, the recycling amount of plastic products in take-away garbage is extremely low, and most of the take-away garbage is incinerated. Why do lunch boxes marked recyclable end up as domestic garbage disposal?
Sheng Min, Secretary-General of China Renewable Resources Recycling Association Recycling Plastics Branch, said that these materials themselves do have recycling value, but the recycling price is not high. Pure polypropylene (PP) transparent lunch box, which is currently used as the mainstream lunch box, is one of the higher quality plastic materials, and the purchase price is only two or three yuan per kilogram. Moreover, after being used as take-away tableware, it is basically impossible to enter the recycling chain.
"From the recycling situation, no matter whether it is a scavenger or a recycling enterprise, he usually only chooses relatively simple types such as coke bottles at the front end. Such a dirty lunch box containing oil stains cannot be recycled." Han Shuo said that most of the wastes did not enter the recycling channel for reuse, but were directly incinerated. If some lunch boxes cut corners in order to simplify the process in the production stage, it will cause more pollution to the incineration treatment, so that the degradable materials themselves are actually "non-degradable".
It is too expensive to separate food from plastic tableware.
In the interview, the reporter also found that almost no one separated the remaining food in the box from disposable plastic tableware. Many discarded plastic lunch boxes contain leftover food.
Should waste food in takeaway garbage be separated from disposable plastic products? The staff of relevant departments said that the cost of secondary sorting and cleaning is high, and the value of recycling plastic products is limited. Therefore, most of them will not be sorted twice.
This statement was recognized by Fang Peng, Ph.D. in Materials Science of Northwestern Polytechnical University and a partner of Beijing Fanrui Technology Co., Ltd. He explained that once food is mixed with disposable plastic products, the cost of sorting is too high. Judging from the current situation, most of these disposable plastic tableware can not be recycled after separation.
At present, paper lunch boxes are the most environmentally friendly. In developed countries, paper tableware is often used for takeout. There are also some foreign fast food and baking businesses in China who choose paper take-away packaging.
Fang Peng said that the raw materials of paper tableware are mostly wood pulp, and then they are pressed and shaped by stamping tools, and then chemical additives are coated on the surface to prevent water seepage. At the same time, paper tableware is also harmless. In some high-end takeaway shops, they usually use this kind of tableware to package food, which looks exquisite. "But the disadvantages of paper tableware are also obvious. First, the price is high, and second, it is impossible to package soup."
There is also a real degradable tableware, which is mainly made of plastic, but with photosensitizer or starch added. Under the action of microbial enzymes in the natural environment, this tableware will be decomposed into carbon dioxide and water, which will not cause harmful effects on the environment. "The disadvantage is also the high price. If there is no special requirement, the merchants will not take the initiative to use it." Fang Peng said.
So how much pressure will the plastic lunch boxes and packaging entering the garbage disposal system bring to the environment? Fang Peng introduced that for plastic waste, incineration and landfill are still two mainstream ways.
It is incumbent on take-away enterprises to fulfill their environmental responsibility.
According to the information released by official website, the daily order volume of Meituan is 12 million, with a cumulative user of 200 million. According to the China takeaway big data released by NGO Sushe citing Hungry, the market size of China has reached 600 million. In 2016, the frequency of online take-away users’ consumption was as high as 63.3%. According to the statistics of this non-profit organization, at least 400 million takeaways "fly in the streets of China" every week, resulting in at least 400 million disposable packaging boxes and 400 million plastic bags, and 400 million disposable tableware discarded.
A lunch box manufacturer said that although the lunch boxes they produced were food grade, the state did not put forward the "degradable" standards or requirements for lunch box manufacturers. If we use 14.6 billion lunch boxes a year now, and each lunch box will increase the cost of 0.5 yuan, the take-away industry will spend 7.3 billion yuan more. Who will pay for these expenses?
"The take-away industry has changed from the Three Kingdoms to two leading companies. At this time, we should consider garbage disposal and environmental protection issues." Someone suggested this.
In Fang Peng’s view, if the policy level can guide and encourage enterprises that are willing to bear environmental costs not to suffer losses, they can use economic leverage to incite the enthusiasm of enterprises through the compensation mechanism, so that maintaining the environment becomes a rational choice for all parties. "Takeaway enterprises should bear the responsibility of recycling plastic lunch boxes and allocate special funds to lunch box recycling or processing enterprises according to sales." Considering the characteristics of Chinese catering, PP lunch boxes can only be used in many cases. "In terms of technology and policy, support PP lunch box manufacturers to develop degradable PP lunch box production technology, sign a recycling plan for PP lunch boxes with take-away merchants and take-away platforms, and advocate diners who use PP lunch boxes to consciously clean their lunch boxes and put them in designated recycling places to facilitate later recycling."
In June this year, Meituan Takeaway, China Cuisine Association and China Environmental Protection Foundation jointly launched the Green Takeaway Industry Convention (Green Ten Articles) with a number of food and beverage take-away brands, including the content of "promoting the use of green tableware", and called on the scientific research community to provide intellectual support for the industry and develop degradable and environmentally friendly lunch boxes with high quality and low price. However, at present, the implementation of the "Green Ten" can only rely on industry self-discipline, and its effect needs time to test.
● Reporter’s Notes
How to crack the garbage pollution of take-away packaging
In many developed countries, the food take-away industry is very prosperous. Why are there no serious take-away garbage pollution in these countries?
The reason is that in these countries, paper and degradable lunch boxes are the mainstream of take-away packaging. In the domestic catering industry, for the sake of cost, most merchants choose cheap plastic lunch boxes and abandon green lunch boxes such as degradable cartons. However, the manufacturing cost of plastic lunch boxes is low, but the environmental cost is very high.
If you only hit the board on the ordering platform, it may be biased. The defects of relevant industrial policies and the imperfect garbage recycling system have greatly aggravated the seriousness of this problem. Just as Fang Peng said, to solve the pollution problem of take-away plastic waste, it is necessary to clearly define the responsibilities of individual consumers, take-away enterprises, garbage disposal enterprises and the government, and all parties should work together.
The state should greatly increase the use cost of plastic lunch boxes and reduce the use cost of green lunch boxes such as paper boxes through tax leverage, so as to curb the source of take-away packaging pollution.
In addition, the pollution of take-away packaging has also exposed the backwardness of the current garbage recycling system. At present, our garbage disposal is still in an extensive stage, and there is no effective classified recycling system. Take-away packaging, as a recyclable resource, has not been effectively recycled, resulting in annoying garbage. It not only causes pollution, but also brings waste.
The take-away ordering platform needs to actively fulfill its environmental responsibilities and cannot turn a blind eye to the problem of increasing garbage. At the same time, it also needs an effective public governance mechanism under the leadership of the government for take-away packaging and garbage recycling. Only by working together can we find a way to crack the "garbage siege" of take-away packaging.
Steamed bread is delicious and nutritious to make hamburgers.
(Reporter Zhuang Yuan) Some citizens usually like to freeze some steamed bread in the refrigerator and store it. In fact, there are many ways to eat steamed bread "recycled". Wang Meng, a professional in the catering industry in this city, introduced two kinds of "steamed bread hamburgers" to the public, which are rich in nutrition.
Cross-cut the steamed bread, divide it into two parts, beat the eggs into a bowl, add a little salt and stir well, then wrap the steamed bread with egg liquid on both sides, fry them on both sides in a pot and take them out. On the fried steamed bread, layer by layer, put the vegetables, fried eggs and bacon, and add mayonnaise or ketchup, mushroom sauce and bean paste. Finally, cover the other half of the steamed bread on the top.
The second flavor can be cooked as a roast chicken leg burger. Bone and peel the chicken leg with a knife or scissors, add salt, pepper and cooking wine, marinate for 5 minutes, and put a little oil in the pot to fry the chicken. Add fried chicken leg meat and vegetables such as lettuce, carrot, tomato and cucumber to the fried steamed bread.
In addition, citizens can also use their imagination to put steak, mashed potato salad, bacon and other ingredients in steamed bread to make a variety of "steamed bread burgers".
