How can the new energy automobile industry be stable and far-reaching

  A few days ago, with a pure electric car driving off the production line, the cumulative production of new energy vehicles in China exceeded 20 million. Experts believe that this marks that China’s new energy vehicles have entered a new stage of high-quality development of scale and globalization on the basis of industrialization and marketization.

  What opportunities and challenges will China’s new energy automobile industry face at present and in the future? How to promote the stability of new energy automobile industry?

  In the first half of the year, production and sales increased by 42.4% and 44.1% respectively.

  New energy vehicles are the main direction of global automobile industry transformation and upgrading and green development, and also the strategic choice for high-quality development of China’s automobile industry. According to the latest data from China Association of Automobile Manufacturers, in the first half of this year, the production and sales of new energy vehicles in China were 3.788 million and 3.747 million respectively, up by 42.4% and 44.1% respectively. The sales volume of new energy vehicles reached 28.3% of the total sales volume of new vehicles.

  Xin Guobin, Vice Minister of the Ministry of Industry and Information Technology, said that since the 18th National Congress of the Communist Party of China, China has taken the lead in establishing a national strategy for developing new energy vehicles, and then formulated industrial development plans for 2020 and 2035. the State Council approved the establishment of a top-level design and promotion mechanism for industrial development, and various departments have successively launched more than 70 policy initiatives to support the development of new energy vehicles. Various localities have introduced supporting policies in light of their own actual conditions, and industrial enterprises have accelerated their innovation and jointly promoted the development of China’s new energy vehicle industry to achieve historic achievements.

  "Through unremitting efforts, China has established a new energy vehicle industry system with complete structure and organic synergy, cultivated the world’s largest consumer market, and formed a good development situation in which new energy vehicles and related industries are symbiotic and win-win." Xin Guobin said.

  Fu Bingfeng, executive vice president and secretary general of China Automobile Industry Association, said that in September 2020, China’s new energy vehicle production exceeded 5 million, and in February 2022 it exceeded 10 million, and it took only one year and five months to achieve the second 10 million.

  At the same time, the brand competitiveness of new energy vehicles in China has been greatly improved. According to statistics, in 2022, the domestic market sales of self-owned brand new energy passenger cars accounted for 79.9%, up 5.4 percentage points year-on-year. In the first half of this year, 534,000 new energy vehicles were exported, a year-on-year increase of 1.6 times.

  Ou Yangming Gao, member of the Standing Committee of Chinese People’s Political Consultative Conference, academician of China Academy of Sciences and professor of Tsinghua University, said that after nearly ten years of rapid development, China’s new energy vehicle and power battery industry has led the world, with the output and quantity ranking first in the world, and achieved large-scale export, which has become a highlight of China’s economy.

  Gradually establish a competitive advantage in the technical field of "Three Electricity"

  Technological innovation is the core competitiveness of industrial development.

  In recent years, the core technology of new energy vehicles in China has continued to break through. For example, the energy density of mass-produced power batteries reaches 300 WHr/kg, which is at the international leading level, and new group technology and high-nickel cobalt-free batteries have achieved breakthrough applications; The peak power density of the driving motor exceeds 4.8 kW/kg, and the maximum speed reaches 16,000 rpm. The average power consumption per 100 kilometers of pure electric passenger cars dropped to 12.35 kWh.

  "China has been in ‘ Sandian ’ (Battery, motor, electronic control) technology has gradually established a competitive advantage. " Fu Bingfeng said that in recent days, the intensive introduction of policies to stimulate consumption potential and strengthen industrial supporting capacity building will further stabilize market expectations and promote high-quality industrial development.

  Of course, we should also see that there are still some problems in China’s new energy automobile industry, such as insufficient supply of key core technologies and the need to improve support and guarantee capabilities.

  "It is the key to industrial transformation and upgrading to establish a multi-field collaborative model of automotive chips, application software and operating systems." Li Shaohua, deputy secretary-general of China Automobile Industry Association, believes that host manufacturers, software companies and research institutes should jointly build and share common technology platforms to enhance the stability and competitiveness of the supply chain.

  Xin Guobin pointed out that the Ministry of Industry and Information Technology will support China enterprises to carry out technical cooperation with foreign enterprises in the fields of new system batteries and autonomous driving, so as to enhance brand vitality through technological innovation. Guide enterprises to establish the concept of product life cycle service, strengthen the construction of digital and network capabilities, and enhance brand affinity with quality services.

  In addition, experts believe that at present, China’s new energy automobile industry still relies on imports of raw materials such as lithium, nickel and cobalt. In the process of rapid development, we should also be alert to risks such as overcapacity and structural contradictions. We should focus on the long-term, fill in the shortcomings, maintain a benign industrial order, and make industrial development stable and far-reaching.

  Further build a high-quality charging infrastructure system

  "This year’s Dragon Boat Festival holiday, our family traveled by car and charged in the expressway service area halfway. Because there are many cars and few piles, the waiting time in line is long, and the charging power is low and it takes a long time, which greatly affects the travel experience." Wang Yongtao, a new energy owner who lives in Daxing District, said.

  Nowadays, with the increasing demand for long-distance travel of new energy vehicles, the expressway service area has become an important scene for charging new energy vehicles.

  Wang Zhongying, director of the Energy Research Institute of the National Development and Reform Commission, said that by the end of May this year, there were 4,289 expressway service areas with charging conditions in China, accounting for about 65% of the total service areas. However, according to statistics, the number of expressway charging infrastructure is about 18,000, accounting for only 0.8% of China’s public charging infrastructure. Compared with the development demand, the problems of insufficient total charging infrastructure, low density and insufficient coverage are still outstanding.

  In addition to "difficulty in charging roads", "difficulty in finding piles" and "difficulty in entering residential areas" are also strong problems reflected by users of new energy vehicles.

  Wang Yao, Secretary-General of China Electric Vehicle Charging Infrastructure Promotion Alliance, said that private charging piles could not be built as needed in old residential areas due to the shortage of parking spaces and insufficient power capacity, and some residential areas still did not cooperate with the property to provide proof materials, which made it impossible for users to install private charging piles. In addition, the problems such as the difficulty in finding the location of public charging piles, the high failure rate of charging piles and the occupation of charging parking spaces are particularly prominent.

  In the long run, the development of new energy automobile industry is inseparable from high-quality charging infrastructure system. "By the end of 2022, the cumulative domestic car-pile ratio in China was 2.5: 1." Ou Yangming Gao said that it is expected that the number of new energy vehicles in China will continue to grow rapidly, and the development of charging infrastructure must be accelerated.

  Recently, the General Office of the State Council issued "Guiding Opinions on Further Building High-quality Charging Infrastructure System", which clearly put forward five tasks: optimizing and perfecting network layout, accelerating the construction of key areas, improving operational service level, strengthening the guidance of scientific and technological innovation, and increasing support and guarantee.

  In this regard, Ou Hong, deputy secretary-general of the National Development and Reform Commission, said that the National Development and Reform Commission and the National Energy Administration will work with relevant parties to strengthen departmental coordination and strengthen guidance and supervision to ensure that all measures are effective as soon as possible.

Hacker examples explain the analysis method of Trojan horse!

There was a domestic model before, and it had a nice name called "Guangwai Girl". This is the work of "Guangwai Girls" network group of Guangdong University of Foreign Studies. It can run on WIN98, WIN98SE, WINME, WINNT, WIN2000 or Win95/97 with Winsock2.0 installed. Compared with the past, it has the characteristics of smaller volume and more ingenious hiding. It can be expected that in the future, it will become another popular Trojan after the "Ice River".

Address quoted in this article: https://www.eepw.com.cn/article/201706/357346.htm.

Because the method of "Guangwai Girl" is typical, I will explain the research method of general Trojan through the detailed analysis process of this new Trojan. The following test environment is the Chinese version of Windows2000.

I. Tools needed

1.RegSnap v2.80 is the best tool for monitoring changes in the registry and system files.

2.fport v1.33 tools for viewing ports opened by programs.

3.FileInfo v2.45a tool for viewing file types.

4.ProcDump v1.6.2 Shelling tool

5.IDA v4.0.4 disassembly tool

Second, the analysis steps

All the tools are ready, and we begin to analyze this Trojan horse. Once the general Trojan horse runs, it will do some tricks on the registry and system files, so we should make a backup of the registry and system files before analysis.

First open RegSnap, select new from the file menu, and then click OK. In this way, we make a record of the current registry and system files, and if the Trojan horse modifies one of them later, we can analyze it. Save it as Regsnp1.rgs after the backup is completed.

Then we will run the "Guangwai Girl" terminal on our computer. Don’t be afraid, because we have made a detailed backup, and we can change the hands and feet it made as it is. Double-click gdufs.exe, and then wait a moment. If you are running Skynet or Kingsoft Internet Security, you should find that these two programs quit automatically. Is it strange? And listen to our analysis later. Now the Trojan horse is already in our system. Let’s take a look at what it has done to us. Re-open RegSnap, select new from the file menu, and then click OK to save the snap result as Regsnp2.rgs.

Select Compare from the file menu of RegSnap, open Regsnp1.rgs in the First snapshot, open Regsnp2.rgs in the Second snapshot, and select show modified key names and key values in the radio box below. Then press the OK button, so RegSnap will start to compare the two records, and what’s the difference? When the comparison is completed, it will automatically open the analysis result file Regsnp1-Regsnp2.htm.

Look at Regsnp1-Regsnp2.htm and pay attention to it:


It means that in the two records, the registry key was not deleted, 15 registries were modified and one registry was added. Look at the back:

The meaning of this passage is that a new file, diagcfg.exe, has been added under the directory C:WINNTSystem32. This file is very suspicious, because we only ran the Trojan named "Guangwai Girl" between two system information comparisons, so we have reason to believe that diagcfg.exe is the backdoor program that the Trojan left in the system. If you don’t believe me, open the task manager and have a look, and you will find that there is a process of DIAGCFG.EXE, which is the original body of the Trojan horse. But don’t delete DIAGCFG.EXE at this time, otherwise the system will not work normally.

Trojans usually set some key values in the registry so that they can run automatically every time the system restarts. Let’s take a look at which registry keys have changed in Regsnp1-Regsnp2.htm. With experience, we should pay attention to the following:

This key value was changed from the original %1 %* to C:WINNTSystem32DIAGCFG.EXE %1 %*, which is the most suspicious because it contains the Trojan horse DIAGCFG.EXE. So what does this registry key do?

It is the format of running executable file, which was changed to C:WINNTSystem32DIAGCFG.EXE %1. % * After that, run the program C:WINNTSystem32DIAGCFG.EXE every time you run any executable file.

It turns out that this Trojan horse has been tampered with here, so that it can run automatically. Its startup method is not the same as that of ordinary Trojans, which are in

Add a key value to the key, so that you can start yourself, but this method is well known by anti-virus software, so it is easy to be killed. The trojan horse of "Guangwai Girl" is more cunning, and it sets the startup item in another position.

Now that we have mastered the location of this Trojan horse and the startup items in the registry, it is also important to find out which port it is listening to. This can be easily achieved by using fport. Run fport.exe on the command line, and you can see:

We can clearly see that the Trojan horse program is listening on TCP port 6267. So far, we can say that we have mastered all the actions of the trojan horse "Guangwai Girl" in our system, and now we can easily kill it.

Third, killing

After the previous analysis, we have understood the working mode of the trojan horse "Guangwai Girls", and now we will clear it. The following is the method to completely remove the "girl students from Guangzhou". Note: the order of this step cannot be reversed, otherwise the Trojan horse may not be completely removed.

1. Press the Start menu, select Run, enter regedit, and press OK. Open the following key values:

But don’t modify it yet, because if you modify the registry at this time, the DIAGCFG.EXE process will still change it back immediately.

2. Open Task Manager, find the process of DIAGCFG.EXE, select it, and press "End Process" to close this process. Be careful, don’t close the process before opening the Registry Manager, otherwise DIAGCFG.EXE will be started when regedit.exe is executed.

Step 3 put

The key value of is changed from the original C:WINNTSystem32DIAGCFG.EXE %1 %* to %1 %*.

4. At this time, you can delete the DIAGCFG.EXE in the directory C:WINNTSystem32. Remember never to delete this file first, otherwise you will not be able to run any executable files in the system. Since we intend to further analyze this Trojan horse, we will not delete it now, but copy it to other directories for research.

Fourth, in-depth study

We already know the basic working principle, start-up process and how to get rid of it completely, but there is still one thing that we have not completely understood, that is, how it deals with Skynet or Kingsoft Internet Security. To understand this deeply, we must look at the code of "Guangwai Girl". This Trojan has not published the source code, but we can still take a look at it by disassembling it.

The end of "Guangwai Girl" is only 96K, which is obviously encrusted with compression software. We must first determine what shell it has added. It can be detected by using the small tool FileInfo. Now we will copy the DIAGCFG.EXE analyzed in front to the directory of FileInfo, then fi.exe at the command line, and then press Enter, and it will display:

FileInfo has detected that DIAGCFG.EXE has used ASPack v1.06b to shell. Knowing its encryption method, we can use ProcDump to shell it.

Run ProcDump, click the Unpack button, because we want to take off the shell of ASPack v1.06b, so we select Aspack108 in it, and then press OK. At this time, it will let you open the file to be shelled, so we will choose DIAGCFG.EXE and open it. Then wait a few seconds and press "OK". ProcDump will shell DIAGCFG.EXE, and then a dialog box will appear asking you to save the shelled file, and we will save it as gwns.exe.

Note: At this time, the Trojan horse runs on your system again, so it must be cleaned up again according to the previous cleaning steps. Since the cleaning method has been written before, I won’t repeat it here.

Well, now we have got the original file of this Trojan horse before it was shelled. Look at the shelled gwns.exe, which is as big as 194k, which is more than twice as big as the original program. This is the credit of the shelling software. Now you can use the disassembler to disassemble it, and then look at its assembler code.

Let’s use IDA to disassemble it. By the way, this IDA is a super disassembly tool, which is a necessary tool for cracker and Windows hacker. Let’s take a look at some of the disassembled code:

Trojan first loads kernel32.dll, and then uses GetProcAddress to get the address of the API RegisterServiceProcess. Trojan first needs to register itself as a system service, so it is not easy to be found by the task manager when running under Win9x. Then it will GetCommandLineA to get the running parameters, and if the parameters are executable files, it will call Winexec to run.

Then the Trojan will find the process of snfw.exe and kav9x.exe, that is, the process of Skynet or Kingsoft Internet Security, and then kill it.

Trojan will also modify the startup items of "Skynet Firewall" or "Kingsoft Internet Security" in the registry, so that it will not run automatically when the system is restarted next time.

The following is to modify the registry startup item of Trojan horse, namely


Item, so that it can start itself every time the system restarts. Next, the Trojan will initialize Winsock dll, bind the port, and wait for the connection of the Trojan client.

V. Summary

Up to now, we have completed the whole analysis process of the Trojan horse program "Guangwai Girl" and learned about the startup and operation mechanism of the Trojan horse. Of course, the purpose of writing this article is not simply to introduce the Trojan horse of "Guangwai Girl", but to introduce the analysis method of the general Trojan horse through the detailed analysis of this typical Trojan horse. Using the analysis method in this paper, you can completely analyze any unknown Trojan horse variety. Finally, let’s summarize the methods and steps of Trojan horse analysis:

First, the system registry and system files are backed up, then the Trojan server is run, and then the registry and system files that have been run by the Trojan are recorded, and the results of the two records are compared by using registry analysis tools, so that we can know what the Trojan has done in the system. Use fport to view trojan listening port. Then, using the obtained information, the method of removing Trojan horses is made.

If you want to analyze the Trojan deeply, you should also shell and disassemble the Trojan server. In this way, you can fully grasp any action of the Trojan horse. Of course, this requires you to have a good grasp of assembly language and a certain degree of patience, because the lengthy assembly code is not completely readable by ordinary novices.

If you want to further analyze the Trojan message format, use sniffer to monitor the Trojan port, and then make a comparative analysis. This analysis method is more complicated, so this article will not give an example.

Just reading the article is not enough. If you want to fully analyze a Trojan horse, you need to practice it! Good luck!

Extract aviation fuel from waste oil! Netizen: This is the correct usage of waste oil.

  Mention gutter oil

  Many people’s first reaction is harmful to health.

  But if you use it in the right place,

  Waste oil can also play its value.

  recent days

  An A350 aircraft was accepted by Air China.

  The plane used 5% sustainable fuel for its first flight.

  Its raw material is waste oil.

  Adopt technology with independent intellectual property rights for production.

  The big plane drank "gutter oil"

  Not only can you sail normally

  It can also achieve green flight.

  The aviation industry has made a key breakthrough in emission reduction.

Extract aviation fuel from waste oil! Netizen: This is the correct usage of waste oil.

  Let "gutter oil" fly to the sky.

  It is by China Petrochemical Research Institute.

  The first bio-jet fuel industrial device developed in China

  The device is made of used cooking oil and edible oil.

  That is, waste oil

  Production of bio-jet fuel as raw material

  (Bio-jet fuel:

  It is aviation kerosene produced with renewable resources as raw materials.

  Raw materials mainly include waste cooking oil,

  Animal and vegetable oils, agricultural and forestry wastes, etc.)

  Compare with that traditional petroleum-based aviation kerosene

  Carbon Dioxide Emission of Bio-jet Fuel in Life Cycle

  The maximum emission reduction can be more than 50%

  The device can "swallow" about 100,000 tons of "gutter oil" every year.

  Spit out 40,000 to 50,000 tons of clear biological aviation kerosene.

  Converted, it can reduce carbon dioxide emissions by about 80 thousand tons per year.

  It is equivalent to nearly 50,000 economical cars being shut down for one year.

Extract aviation fuel from waste oil! Netizen: This is the correct usage of waste oil.

  It can be basically digested in one year.

  Waste oil recovered from a city with a population of 10 million.

  Some netizens said:

  "This is technology and hard work!"

Extract aviation fuel from waste oil! Netizen: This is the correct usage of waste oil.

  I didn’t expect it.

  The gutter oil that everyone "abandoned" one day

  Can be turned into high-value fuel.

  This is the proper way to turn waste into treasure.

Concept of Community of Human Destiny: Correctness and Innovation of Marxism in China

Author: Cui Xiao, Ph.D. candidate of Communication Institute of Communication University of China and part-time researcher of Media and Public Affairs Institute.

Marxism has provided a powerful ideological weapon for China’s revolution, construction and reform. At the same time, the proposition of China Marxism has been advancing with the times. As the practice of Marxism in China in specific scientific, the concept of community of human destiny is an innovation in adhering to Marxism in China.

1. The deep cultural connotation of the concept of community of human destiny.

The concept of the community of human destiny is extremely rich in connotation, and its core is to build a world of lasting peace, universal security, common prosperity, openness, tolerance, cleanliness and beauty as pointed out in the report of the 19th National Congress of the Communist Party of China. Accordingly, we need to interpret its deep connotation from five aspects: politics, security, economy, culture and ecology. What needs to be clear is that these five levels are not separated from each other, but permeated with each other, and their relationship is like an intertwined five rings, blending with each other in connotation (Figure 1).

Concept of Community of Human Destiny: Correctness and Innovation of Marxism in China

Figure 1 Deep cultural connotation of the concept of community of human destiny

1.1 Political level

The first is the way to get along with each other with mutual respect. "Love, people love; Those who respect others will always respect them. " The concept of the community of human destiny emphasizes mutual respect and equal consultation, resolutely abandons the cold war mentality and power politics, and takes a new path of state-to-state exchanges of dialogue without confrontation and partnership without alignment. This kind of advocacy is a way to get along with each other based on the objective facts of the international community. In the context of increasingly frequent international exchanges, political mutual respect is the premise and foundation for cooperation between countries.

The second is the development path of win-win cooperation. "if you want to stand up and stand up, you want to reach people." "Everyone gathers firewood and the flame is high." Win-win cooperation is one of the ideological sources of "the community of human destiny", and it is also a link between ancient and modern China’s traditional cultural concepts. Under the background of deepening globalization, win-win cooperation is the direction and goal of cooperation between countries.

1.2 Security level

The first is the principle of coordination to turn hostilities into friendship. "Being in harmony with others means being happy; He who is in harmony with heaven is called heavenly joy. " China is a civilized body advocating stability, and "harmony is the most important thing" is the national spirit of Chinese. Resolving disputes through dialogue and resolving differences through consultation embodies the cultural concept of "turning hostilities into friendship".

The second is the global vision of Concord Wanbang. "the trip to the avenue, the world is public." This ancient concept of "harmony" is integrated into the concept of the community of human destiny, guiding cooperation and exchanges between countries with new values of the times. Driven by information technology, the connotation of "global security" has been changing all the time, but one thing has never changed, that is, the deepening interests of human beings are blended and shared. The narrow view of national interests of egoism and populism is untenable, and the common security concept of one glory and one loss can stand the test.

1.3 Economic level

The first is an open and inclusive development tolerance. Opening to the outside world is the basic national policy of China, and only in an open environment can it develop better. This development bearing of China’s leading by example is the self-confidence and calmness of "doing what you can’t do against yourself", and it also reflects the profound understanding of the material foundation needed to build a community of human destiny.

The second is the balanced development and cultivation of universal benefits. For the progress of human civilization, development is the first priority. For development, the balanced distribution of social resources and the balanced production of social wealth are the key to solving social poverty. The pursuit of balanced development and self-cultivation of universal benefits embodies the way of governing the country and ensuring peace in China culture of "not suffering from poverty but suffering from inequality".

1.4 Cultural level

One is the philosophical wisdom of harmony but difference. Philosophy is the culture of thought. As a cultural representation, the concept of the community of human destiny also contains the philosophical wisdom contained in this culture. This kind of philosophical wisdom is embodied in the dialectical thought of "all things are bred without harming each other, and the Tao is parallel without contradicting each other" and the natural Tao of "the terrain is vast, and the gentleman carries things with virtue".

The second is the concept of prosperity between the United States and the United States. "A single flower is not spring, but a hundred flowers bloom in spring.". Advocating the concept of "respecting the diversity of world civilizations, transcending the barriers of civilizations through civilized exchanges, transcending the conflict of civilizations, and transcending the superiority of civilizations through coexistence of civilizations" is full of the prosperity concept of beauty and beauty.

1.5 Ecological level

The first is the ecological wisdom of harmony between man and nature. Tao Te Ching puts forward that "man should follow the earth, the earth should follow the heaven, the heaven should follow the Tao, and the Tao should follow the nature", and Zhouyi calls "heaven and earth" as "three talents". This idea of "harmony between man and nature" has been absorbed by the concept of the community of human destiny, forming a distinct ecological wisdom: on the one hand, all countries should respect and protect nature as the basic yardstick for developing modern science and technology; On the other hand, international cooperation between countries should be based on improving the living environment of human beings.

The second is the ecological morality of sustainable development. Marxism puts forward that "man lives by nature" about the relationship between man and nature. Pursuing environment-friendly human development is a basic ecological morality. We should take the road of green, low-carbon and circular sustainable development and build a global ecological system that respects nature.

2. The way to keep the concept of the community of human destiny right: the historical foundation

The concept of community of human destiny is the persistence and inheritance of Marxist thought. This kind of rightness ensures its profound historical foundation.

2.1 adhere to the people-centered "people-oriented" orthodoxy

Marxism is an idea of seeking liberation for mankind. In the Economic Manuscripts of 1857-1858, Marx proposed that in the new social system in the future, production will aim at making all people rich. The concept of the community of human destiny fully demonstrates its "people’s nature" and expands this "people’s nature" from our own country to the whole world, from our own nation to all mankind, which meets the people’s yearning for a better life all over the world and also demonstrates the Communist Party of China (CPC)’s ideal and belief that human society will eventually move towards communism.

2.2 adhere to the "innovative" tradition of continuous innovation and development.

As a Marxist political party, the Communist Party of China (CPC) always maintains the advanced nature of pursuing innovation and forging ahead. It is on the basis of inheriting this "innovative" spirit that the Communist Party of China (CPC)’s leading collective in the new era conforms to the development trend of the times and the law of social development, and puts forward the concept of a community of human destiny, which promotes the transformation of human development concepts and communication concepts through creative expression.

2.3 adhere to the "practical" orthodoxy that theory originates from practice.

Marxism is a practical theory, not a study. The basic viewpoint of Marxist epistemology is to solve specific problems from practical life. The concept of the community of human destiny is the concrete manifestation of this "practicality" of Marxism in the new era, which itself contains a profound sense of global anxiety and provides a new guiding concept for solving the problems of human social development.

2.4 adhere to the people’s democratic thinking of the "democratic" orthodoxy.

Marx and Engels pointed out that the proletarian movement is an independent movement for the benefit of the overwhelming majority of people. On the road of socialist development, China has always insisted on promoting the construction of democratic politics under the leadership of the Communist Party and realizing consultation and common governance. In the concept of the community of human destiny, the way of getting along with each other with mutual respect and the principle of coordination to turn hostility into friendship are all direct manifestations of "democracy."

2.5 adhere to the "symbiotic" orthodoxy of the relationship between man and nature.

Marx believes that "man lives by nature", and labor links man with nature. The ecological wisdom of the unity of man and nature and the ecological morality of sustainable development contained in the community of human destiny are exactly the insistence of Marxism on the "symbiotic" relationship between man and nature. The COVID-19 epidemic that broke out at the end of 2019 spread all over the world, and no country can "enjoy the unique scenery here". "The whole world is cool and hot here" warns the close connection between human destiny and the fate of human and nature.

2.6 adhere to the unity of personality and social "thinking" orthodoxy.

"Quasi-thinking" is an important concept in Marxist philosophy. We can understand that the whole human society is relationship-based rather than individual-based, and the existence of individuals is based on the existence of the whole. People cannot live independently without the relationship with others and everything, and form a community in their relationship with each other. The "quasi-thinking" focusing on human beings transcends the division caused by "special classes" and "interest groups", helps human beings break through the shackles of various social roles, seek consensus from values that transcend national and national boundaries, such as peace, justice, democracy and tolerance, and realize identity and free association in the essence of "people".

3. The way to innovate the concept of the community of human destiny: the characteristics of the times

Mankind has been a community of destiny since ancient times. Thinkers at all times and in all countries have expressed different ideas about the community, and their understanding of it has gradually developed from primitive clans and tribes to nations and countries, and then to a higher-level community of human destiny. The Marxist thought of "the association of free men" contains the community spirit that transcends ethnic boundaries. The concept of the community of human destiny is not only a adherence to the China-oriented orthodoxy of Marxism, but also a reflection of China’s in-depth investigation of the times and the world, and a new theory and practice put forward to keep up with the new situation and new requirements. This kind of innovation has cast its distinctive characteristics of the times.

3.1 reflects the adaptation to the law of global social development.

Nowadays, the pace of globalization is steady and far-reaching. However, the world still faces many challenges and uncertainties. On the one hand, the international political situation is unstable, and a separatist and nationalist tendency has begun to spread, and some countries have added obstacles to international cooperation and development because of their "fragmented"; On the other hand, challenges such as terrorism, financial turmoil, environmental crisis, regional conflicts, poverty and diseases remain unabated, and local problems may turn into global challenges at any time. In this environment, human beings need to establish a sense of community of destiny with an empathy to cope with global risks and tests.

3.2 reflects the response to the requirements of the times and international concerns.

As a node in the community of human destiny, the country’s activities not only reflect the requirements of the times, but also affect international concern. Facing the requirements of the times, the increasingly prosperous China needs to play a better role on the world stage; Faced with international concerns, the growing China needs to answer a series of important questions, such as "what road to take in the future and what impact it will bring to the international community". The concept of the community of human destiny is not only the wisdom and scheme contributed by China in response to the requirements of the times, but also the responsibility and responsibility of China in the face of international concerns.

3.3 reflects China’s active participation in global governance.

Nowadays, the world is facing severe challenges. No government, enterprise or individual can cope with them alone, and many problems cannot be solved in isolation. It is necessary to formulate a "systematic plan". Focusing on the five levels of the connotation of the community of human destiny, the Chairman of the Supreme Leader put forward the "five persistences" of building a "community of human destiny", which is a set of "systematic programs" for global governance. It embodies the systematic view of dialectical coordination between the local and the whole, and requires grasping the relationships among all parts and aspects in the system.

3.4 reflects the improvement and revision of the international discourse system.

According to the Marxist view of news communication, human information communication activities are a spiritual communication process of emotion, value and thought, and "communication" becomes the philosophical logic of information communication. For a long time, mass media has made communication have some top-down "elite" characteristics, and the importance of interpersonal communication based on interpersonal communication has not been highlighted. At the same time, the western media has dominated the international news information order for a long time, which also makes the international discourse system under the leadership of the news concept with the critical supervision as the guidance and the conflicting framework as the narrative mode, and holds the binary opposition thinking of other news concepts. With the continuous empowerment of social media, the public’s subjectivity has returned, and the international community is welcoming an era of public communication. Under this trend, the traditional western news concept can no longer adapt to the overall construction of the international discourse system. At present, the rise of constructive news oriented to problem solving and negotiation dialogue is an innovation under this trend. The idea of "community of human destiny" that pursues the consensus of multiple voices provides a perspective for thinking about how to meet an era of public communication, and also provides a path for shaping the international discourse system, and promotes the global information exchange from "self-awareness" to "community awareness" and from "self-talk" to "community dialogue".

The community of human destiny stands at the origin of the coordinate axis of Marxism in China (Figure 2), ensuring the coexistence of historical roots and characteristics of the times with integrity and innovation, which is also the basis for it to stand the test and maintain its vitality forever.

Audi R8 e-tron self-driving concept car launched in the world.

    [XCAR domestic new car original]

    At the first CES ASIA, which recently opened in Shanghai, Audi’s R8 e-tron piloted driving concept car made its world debut. The car adopts pure electric drive, and the maximum cruising range is 450km, which can realize automatic driving.

    Tip: Audi R8 e-tron piloted driving can realize automatic driving; Pure electric drive

The car adopts pure electric drive, and the cruising range of pure electric is more than 450km, which can be realized.

 

    It can be said that this is a "future" car with dual motor drive, carbon fiber lightweight body structure, the latest lithium-ion battery technology, CCS hybrid charging system and automatic driving function.

    However, in terms of design, the car tends to be consistent with the new generation Audi R8 e-tron that was first launched at the 2015 Geneva Motor Show, but some differences can be seen in the details.

The car adopts pure electric drive, and the cruising range of pure electric is more than 450km, which can be realized.

    It is reported that in order to reduce the weight of the car body, some parts of the R8 e-tron self-driving concept car body are made of aluminum alloy and carbon fiber resin composite (CFRP).

 

    In terms of power, the Audi R8 e-tron self-driving concept car is equipped with a pure electric system. The maximum power of the two motors is 170kW(231Ps) and the peak torque is 460Nm. The total power output is 340kW(462Ps) and the combined torque is 920Nm.

The car adopts pure electric drive, and the cruising range of pure electric is more than 450km, which can be realized.

    Under this system, the 0-100km/h acceleration time of the car is 3.9 seconds, and the maximum speed is 250 km/h. In addition, in pure electric mode, its cruising range can reach 450 kilometers, and it will not be fully charged for more than 2 hours.

The car adopts pure electric drive, and the cruising range of pure electric is more than 450km, which can be realized.

    As for the auto-driving, which is emphasized by the car, it can only be understood at present that because it is equipped with a new laser scanner, ultrasonic sensors, multiple video cameras and radars, the information can be converted into signals and sent to the central controller (zFAS) to "know" the surrounding environment of the car well. 

The car adopts pure electric drive, and the cruising range of pure electric is more than 450km, which can be realized.

    Edit commentsLike the former new energy vehicles, the emerging driving technology concepts such as driverless and autonomous driving are setting off an upsurge, but I don’t know how far pure autonomous driving will go into our real life. Because at present, autonomous driving is basically used as an auxiliary driving function to play its "charm" in production cars. So, maybe the real driverless and autonomous driving will come soon, or maybe for the time being, it is just an inspiration and beautiful imagination for future driving technology.

The eyebrow tattoo experience of 25-year-old white-collar workers in Yang Mei: The service is professional and intimate, and it is hard to make people not love it!

In this era of beauty-loving, every girl hopes that her face value can be improved higher, among which eyebrows play an important role in the temperament of the five senses.

Recently, after eyebrow tattooing, many sisters have been asking me: Is eyebrow tattooing good? Will it be tattooed? How long can tattooed eyebrows last? Today, I will share with you my experience in eyebrow tattooing, hoping to help you.

Although many people now say that tattooing eyebrows is easy to step on thunder, what I want to say is that this is related to technology, eyebrow tattooing products and the level of eyebrow tattooers. 

Before tattooing eyebrows, I searched the Internet to learn about all kinds of tattooed eyebrows, and after comparing with different tattooed eyebrow shops, I finally chose Yang Mei tattooed eyebrows, because their design styles are in line with what I want, and the prices are very reasonable. After tattooing your eyebrows, you can finally get rid of the trouble of going out to thrush every day.

Under the communication design with the eyebrow tattoo artist, I chose the wild eyebrow. When designing the eyebrow shape, the teacher carefully helped me analyze the face characteristics and customize the eyebrows according to the face shape.

picture

The technique of eyebrow tattooing is very important. If the technique is not up to standard, the effect of tattooing will be unsatisfactory. All eyebrow tattooers have qualified tattoo artist qualification certificates, and their operating experience is more than 5 years.

The material of eyebrow tattoo is also very important. Inferior materials may cause skin allergies, fade into blue eyebrows and red eyebrows in the later stage, and pure plant dyes are used for the eyebrows, which can perfectly guarantee the later effect of customers.

The decoration style of Yangmei Store is simple and advanced, and the supplies are all changed by one customer. There is no tingling and discomfort during the operation, and there is no price for selling products during the operation. The operation process is between one and two hours.

picture

The final effect after eyebrow tattooing is the same as the eyebrow shape when it is designed. The wild eyebrows have distinct roots and the flu is bursting, just like their own growth.

The eyebrow shape can be maintained for 3-5 years, and it can be repaired again for free in case of color fading. After the eyebrow tattoo, the teacher will also send drinks, fruits and later care products intimately, and remind you of the precautions after eyebrow tattoo.

picture

Finally, I really like the eyebrow shape designed. The attitude of the eyebrow tattoo artist is really very good, and the follow-up guarantee is also in place. The whole eyebrow tattoo process is very pleasant.

After tattooing eyebrows, it really saves time and can become beautiful. Sisters are also crazy after seeing it. No wonder Yang Mei can stand out from so many tattoo shops!

Tesla is not restricted from licensing, but car data security will be regulated.

abstract:intelligent automobilegeneratedData acquisition fromFrom transmission to processing, the whole life cycleexistSecurity risk, especially cross-border data transmission. The data assets that car companies compete for may threaten national security.

Text | Caijing reporter Liu Yuyuan Editor | Shi Zhiliang

On April 6th, a high-definition picture taken by a Tesla in-car camera released by a foreign hacker attracted widespread attention. The clarity and color richness in the video picture were extremely high, and the faces and movements of the people in the car were clearly photographed.

Many netizens in China also commented, fearing that Tesla cameras would invade personal privacy. "Tesla should understand that the privacy involved in the car is not what you want to take, you can take it!" Weibo, official of Xinhua News Agency, commented. In response, Tesla responded that the cab camera is currently not activated in markets outside North America.

On April 7th, there was a rumor on the Internet that dmv, Pudong, Shanghai restricted Tesla owners from licensing. "My friend is not a Tesla owner, but he heard a staff member at the vehicle management office saying that Tesla can’t handle business and doesn’t have to queue up." Netizen Zhang told Caijing reporter.

On April 8, when Caijing reporter visited Pudong Vehicle Management Office, he learned that there were no relevant regulations. At present, all Tesla businesses can be handled according to the process. However, the person in charge of the pre-trial number window said that there were indeed two or three hours yesterday to suspend the licensing of Tesla’s old cars and other related businesses, but there were no restrictions on the licensing of new cars, and the specific reasons were unknown.

People in Tesla’s marketing department, who did not want to be named, told Caijing that they had not heard of the Shanghai Vehicle Management Office’s restrictions on Tesla’s licensing. Some netizens speculated that the "rumor" that Tesla was restricted by the vehicle management office originated from the recent storm that Tesla’s in-car camera violated the privacy of the owner.

Caijing reporter learned from Professor Yang Diange, the founding president of Tsinghua University Institute of Vehicles and Transportation, that data security and innovation should not be neglected, but cross-border transmission should be strictly managed under the condition of incomplete technical means and imperfect management system.

"The simplest solution is to introduce some very strict regulations to prevent it from using these data, but it blocks the road of technological innovation. In 2020, the Ministry of Industry and Information Technology organized a series of standards, which clearly defined personal information, sensitivity and graded protection, so you don’t have to worry too much. " Yang Diange said.

Subtitle 1:Deep in the privacy storm, Tesla frequently responded.

Unmanned driving requires a large number of data samples from the car and the road, which is also the root of Tesla’s autonomous driving technology. Tesla’s "shadow mode" under Autopilot can use its hundreds of thousands of customer cars equipped with a series of sensors to collect road and driving data, test and strengthen its automatic driving system.

However, Tesla’s collection of user data once triggered discussions on user privacy and data sovereignty. In the past month, Tesla has been on the hot search many times because of data and privacy issues.

On March 20th, elon musk, CEO of Tesla, talked with Xue Qikun, an academician of China Academy of Sciences and president of south university of science and technology of china, at the China Development Forum. He said that Tesla would not use the collected data for espionage, because it would seriously affect Tesla’s development.

"Tesla is willing to use the highest level of confidentiality measures and hopes to create a future of mutual trust with everyone." Musk’s remarks seem to respond to a previous rumor: a notice from a resident of a suspected military compound shows that Tesla is equipped with a series of technical devices that can expose the target position. In order to ensure military secrets, it is forbidden to enter and park the brand vehicles in the area where the family courtyard belongs.

In a report in March, The Wall Street Journal also quoted insiders as saying that the China government began to restrict the use of Tesla by military personnel and employees of key state-owned enterprises, and some institutions required employees not to drive Tesla to work, and prohibited them from driving into residential areas of sensitive enterprises. Bloomberg reported that authorities in China asked Tesla owners to park their cars outside sensitive property to prevent the on-board camera from collecting data.

The aforementioned Tesla people said that the incident of prohibiting Tesla from entering the military compound was true.

In addition to the environment and route photographed by the camera outside the car, Tesla’s in-car cab camera has also been accused of violating the privacy of the owner recently. On April 6, a high-definition picture taken by a Tesla camera released by a foreign hacker attracted widespread attention.

In response, on the morning of April 7, Tesla responded that the cab camera has not been activated in markets outside North America. Even in the United States, car owners are free to choose whether to open it or not. Tesla is equipped with a network security system with the world’s leading security level to ensure the privacy protection of users.

Previously, Tesla’s in-car camera has repeatedly raised questions from foreign netizens. Musk once said on Twitter that he would take back the trial rights of some car owners’ FSD beta (fully autonomous driving beta) because these car owners did not pay enough attention to the road conditions when using the FSD beta function. Some netizens asked, "How does Tesla know the behavior of the owner? Is the camera in the car facing the driver?" Musk clearly answered the netizen: "Yes."

The core of Tesla’s questioning is why the camera facing the owner should be placed in the car. Musk’s response suggests that Tesla’s camera is used to monitor whether the driver is driving safely. However, take the Model 3 model with a camera above the rearview mirror as an example. Although the Owner’s Manual tells the location of the camera and is in a state of "not yet activated", it does not specify the function of the camera.

In fact, it’s not just Tesla who has a camera in the car.

There are as many as 14 body cameras in Xpeng Motors P7, among which one camera is installed above the steering wheel in P7. However, at present, P7′ s official website configuration introduction and user manual do not introduce this camera and its purpose.

Weilai proposed in the Privacy Policy that the camera in the car is on standby after being powered on, and will not take photos, video or collect other personal information except for a few special circumstances. Special circumstances include: in order to detect fatigue driving, facial information such as whether the driver closes his eyes will be collected; When the courier opens the trunk or the vehicle is stolen, the camera on the roof will take photos or take pictures: the airbag will trigger related functions after it pops up, and actively collect the image data in the car when the user does not answer.

In addition, Zhiji Automobile, which is about to be released in mass production, has also installed the super car intelligent camera system Carlog in the car, but it is mainly used to help the car owner shoot the scenery of the front windshield that simulates the car owner’s perspective.

From the functional point of view, the camera in the car is helpful to improve driving safety and provide users with images in the car, but the opposite of safety is often the risk of privacy invasion.

Subtitle 2: Tesla and other foreign car companies.It is necessary to establish a data center in China.

On February 8 this year, five ministries and commissions, including the State Administration of Markets, interviewed Tesla about its OTA function. What caused widespread controversy was that the Central Network Information Office appeared in five ministries and commissions.

Data-driven and software-driven have become the symbols of many smart car companies, and the data contributed by car owners has also become one of the most valuable assets of car companies, but data security and user privacy have always been in a controversial stage.

The data generated by smart cars are mainly divided into two parts. One is vehicle data, including geographic location, system information and business-related data. The other category is mainly user data. After the car networking application quickly gets on the bus, the car is more like a mobile phone, with a large number of rich applications, and WeChat will also access the user account, including access records. On the other hand, some new application scenarios, such as in-car cameras and in-car microphones, will also involve users’ personal data privacy.

On April 7th, in the "Focus Observation" column of China electric vehicle committee of 100, Caijing reporter learned from Professor Yang Diange that the road information collected by smart cars to improve autonomous driving technology is likely to be illegally collected and endanger national security.

"In the process of vehicle driving, the lidar collects the driving data outside all the time, and the camera also collects the information of the road surface all the time. This information is likely to involve sensitive locations and the content is illegal. Not only is the content illegal, but some laser radars have high accuracy, which may cause illegal accuracy and should not achieve such high accuracy. " Yang Diange said.

The owner’s privacy is also threatened. Wang Pengpeng, a special associate researcher at the School of Law of East China University of Science and Technology, told Caijing that according to the law, the data generated in the use of automobiles must be "desensitized" before they can be transmitted, stored and applied in the intelligent research and development of automobile enterprises, and the privacy sensitive privacy data of the owners can also be screened out.

"At present, the data security and data attribution related to automobiles are still in the legal blank stage, but what is more questioned at present is that some data collected by automobiles, such as action tracks, must have human attributes, and legally it is information that needs to be desensitized, which may greatly reduce the technical contribution to deep learning of driverless automobiles." Wang Pengpeng said.

In his view, to balance data security and technological progress, a better solution is to establish a data platform processing center, but the government must be involved in supervision, especially foreign-related enterprises like Tesla.

According to the "Intelligent Networked Automobile Manufacturing Enterprises and Product Access Management Guide (Trial)" (hereinafter referred to as the "Opinion Draft") issued by the Ministry of Industry and Information Technology on April 7, intelligent networked automobile manufacturing enterprises should collect, use and protect personal information according to law, implement data classification and classification management, formulate important data directories, and must not disclose sensitive information related to national security.

It is worth noting that it is mentioned in the Opinion Draft that personal information and important data collected and generated during operations in People’s Republic of China (PRC) should be stored in China in accordance with relevant regulations. If it is really necessary to provide it overseas due to business needs, it shall be reported to the competent department of industry.

Cross-border data transmission of smart cars is a new problem, which is actually related to national security. However, there is no effective supervision mechanism for data transmission at present, and it is very difficult to rectify and repair the data as long as it is spread out, such as classified geographic information.

"In the case that our technical means are not complete and our management system is not perfect, we should adopt a strict management method for cross-border transmission. We should’ block’ the data as soon as possible and put it in China, and it is not allowed to flow out. After the study is clear, these desensitized data that really need to be transmitted and not classified can be transmitted for joint research and development in the global scope. However, before the research is clear and the control means are perfect, the data should be strictly stipulated to stay in China. " Yang Diange said.

The industry predicts that after the release of the Opinion Draft, foreign car companies such as Tesla need to set up a special data processing center in China, just like Apple’s data center in Guizhou.

In July 2020, BMW Group and Tencent jointly established a computing center to develop autonomous driving technology and products that are more in line with the China market. According to relevant sources, the platform will land in Tianjin.

In June, 2020, it was reported in shanghai securities news that the user data and authentication service of Tesla China will be moved from the United States to China, that is, the server will be moved to China, thus solving the problem of unstable connection of Tesla App and meeting the data processing and storage requirements of sensitive information.

Shanghai’s latest residential water price adjustment plan is released! How much will the monthly water fee increase? See the detailed explanation of the question and answer →

Shanghai will raise the water price of residents in Shanghai, which has not changed for nearly 8 years.

On the afternoon of 16th, the Shanghai Municipal Development and Reform Commission announced the latest "Water Price Adjustment Scheme for Residents in the Service Area of Shanghai Water Supply and Drainage Enterprises". At the same time, a hearing on water price adjustment for residential users will also be held on the 31st of this month to listen to the opinions and suggestions of all sectors of society on the water price adjustment scheme for residential users in municipal water supply and drainage service areas.

What changes does this adjustment specifically include?

Let Xiaobian "focus" on you one by one.

1. Q: Which areas of Shanghai residents are involved in the price adjustment?

A: This adjustment covers the water price of residents in the service areas of municipal water supply and drainage enterprises in Shanghai, that is, Shanghai Chengtou Water (Group) Co., Ltd. and Shanghai Pudong Veolia Water Supply Co., Ltd.

It involves Huangpu District, Jing ‘an District, Putuo District, Xuhui District, Yangpu District, Hongkou District, Changning District, Minhang District, Baoshan District, and parts of Pudong New Area and Jiading District.

2. Q: What changes have been made to the water price?

A: The residential ladder water price standard has been raised, as follows.

The comprehensive water price of the first step: adjusted from the current 3.45 yuan per cubic meter to 4.09 yuan.

This price includes two parts: the water supply price is 2.27 yuan per cubic meter, and the sewage treatment fee payable is 1.82 yuan per cubic meter.

Second step comprehensive water price: adjusted from the current 4.83 yuan per cubic meter to 5.72 yuan.

Third step comprehensive water price: adjusted from the current 5.83 yuan per cubic meter to 8.63 yuan.

-The price comparison relationship of water supply price ladder is adjusted to 1:1.7:3, and the sewage treatment fee payable is consistent with that of the first ladder, and the comprehensive water price of the second and third steps is adjusted accordingly.

3. Q: Is there any change in the water quantity of the step?

A: The water quantity of each step of residents remains unchanged.

The water quantity of the first step corresponds to 0-220 cubic meters per household per year (inclusive);

The water quantity of the second step corresponds to 220-300 cubic meters per household per year (inclusive);

The water quantity of the third step corresponds to more than 300 cubic meters per household per year.

4. Q: How much will the monthly water bill actually increase?

A: According to the monthly domestic water consumption of 15 cubic meters per household, the monthly water fee expenditure of each household is about 51.75 yuan before adjustment and 61.35 yuan after adjustment.

Taking 61.35 yuan as an example, this figure accounts for 0.42% of the per capita disposable income of urban permanent residents in Shanghai (calculated according to the statistical data of Shanghai in 2020). The increase in water charges accounts for about six tenths of the average disposable income of households.

5. Q: Is there any change in the preferential policy standard of "one household with many people"?

A: The reporter from Dongfang. com learned that the current preferential policy of "one household with many people" for ladder water price in Shanghai does not involve adjustment and remains unchanged.

[Extension] What is the preferential policy of "one household with many people"?

Families with a large registered population can apply to increase a certain ladder base. The ladder base for increasing water consumption is 100 cubic meters of water per household per year.

Since September last year, the scope of the preferential policy of "one household with many people" has been expanded from the original registered residents who have the same household to those who hold the Household Registration Book, the Residence Registration of Persons with Separate Household Registration in this Municipality, and the Shanghai Residence Permit (including the residence permit for overseas talents) and live together at the same address.

If the cumulative number of people is more than 5, they can apply for increasing the ladder base of water, electricity and gas consumption, and if the cumulative number of people is more than 7, they can apply for the implementation of the average residential ladder price. Each resident user can only apply at one address, and cannot apply at multiple addresses.

6. Q: How do you know which ladder your water consumption belongs to?

A: It can be found through the monthly water bill and the "Shanghai Water Supply" APP just launched in August this year.

The "Shanghai Water Supply" APP has service functions such as business handling, inquiry and payment, fault repair, complaints and suggestions.

How to use it —— Search for "Shanghai Water Supply" in APPle [App Store] or Android [App Store] and download the app. After completing the registration and account binding, you can open an account for residents, transfer residents, register residents in real-name registration system, and automatically push electronic invoices online.

7. Q: What is the current water quality of tap water in Shanghai?

A: The reporter from Dongfang. com learned that the water quality of Shanghai is assessed according to the national standard, and the comprehensive pass rate has reached 99.8%. In order to ensure the safety of water supply and improve the quality of drinking water, Shanghai water supply industry has taken many measures in recent years.

First, build an ecological reservoir, increase pretreatment facilities of sodium hypochlorite and powdered activated carbon, and continuously improve the quality of raw water.

The second is to carry out advanced treatment and transformation of water plants, and continuously improve the water quality of the factory. The advanced treatment rate of the city has increased from 19% in 2013 to 60% at present. Third, through the rolling renewal of the old pipe network and the renovation of the secondary water supply facilities in residential buildings, online monitoring points and secondary water supply sampling points of the pipe network are set up, and the terminal water quality detection index and frequency are increased to continuously improve the terminal water quality of the pipe network.

At present, compared with the end of the "Twelfth Five-Year Plan", the water quality of Shanghai’s pipe network has decreased by 31%, and the water quality is clearer. The chroma drops by 37%, making the look and feel more transparent; The residual chlorine decreased by 25%, and the taste was further improved. The permanganate index of organic matter in water decreased by 26%, making drinking water healthier and safer.

During the "Tenth Five-Year Plan" period, Shanghai will accelerate the advanced treatment and transformation of water plants, and the advanced treatment rate of water plants will reach 90% in 2025, and the renewal of 2,000 km old water supply pipe network will be completed simultaneously, and the water quality management of raw water, factory water, pipe network water and secondary water supply will be continuously strengthened to continuously improve the drinking water quality of citizens.

Long press the picture.

Li dingzhuo beyond the study of qidan characters

    A few days ago, I read the last words of into thin air before Li Dinggan, an interpreter of Qidan literature, published in The Paper Shanghai Book Review on June 24th, 2017. Hereinafter referred to as "Gao Wen"), this paper introduces his collection of seventeen old files of Zhonghua Book Company, reveals Li Dinggan’s little-known experience, and commends his research on Qidan characters, which makes people feel deeply.


 


    Li Dinggan’s entry into the public’s field of vision is inseparable from his study of Qidan characters. Gao Wen’s introduction to Li Dinggui’s life mostly comes from Liu Fengkui’s "Li Dinggui’s Life and Study on the Fine Print of Qidan" (see The Compilation of Qidan Characters), with occasional supplements. Previously, several articles introducing Li Dinggan’s life were mostly due to the study of Qidan characters. Due to various factors, the introduction of Li Dinggan’s life is sometimes incorrect. Due to the limitations of materials, such as his family background, study experience, research interest and style, it is difficult to see Li Dinggan’s true face, which makes people feel sorry.


 


    I don’t study the Khitan characters, but I like reading articles about the study of unpopular characters. Although I swallowed the dates, I can feel the academic spirit of my predecessors. The life of Mr. Luo Fucheng, Wang Jingru and Li Dingzhuo, as well as their course of governing the Khitan script, were gradually understood in such an unsophisticated reading. In particular, Li Ding-gan, who was unlucky, had a rough half-life, and his learning was actually annihilated, which made people feel deeply. Reading Gao Wen, I read that "it can be said that it is the responsibility of our oriental language and literature researchers to collect historical materials about Li Dinggan’s life and restore his legendary but unfortunate life". Inspired by him, he spent two days trying to trace Li Dingzhuo’s life clues, but unexpectedly he gained a lot.


 


    At first, taking advantage of the convenience of the E-era, I searched in the newspapers and periodicals of the Republic of China, and got dozens of articles about Li Dingzhuo, covering religion, translation, poetry, western learning and other fields. It’s surprising that it covers a wide range of fields. Following the clues, we found two issues of Integration, edited by Li Dinggan, in the periodical library of the Republic of China of the National Library of China, and copied a copy of A Record of the Scar of Crimson in the Microform Center. Walking down like this, I suddenly found that Li Dingji is not far from us, and the materials about him are not as scarce as before. This batch of materials is very valuable for us to understand Li Dinggan’s life and spirit.


 


    In the late 1940s, Li Dinggan founded Integration magazine at his own expense. According to the examples listed on the cover of the inaugural issue, the contents of the magazine mainly focus on four parts: writing, learning skills, philosophy and ethics, with the aim of "knowing the past and the present from the outside, saving oneself and saving the country and the world". Although the inaugural issue is a thin volume, the catalogue is divided into more than ten categories, such as treatises, literary records, poetry records, ci records, music records, quotations, Shi Shuo Xin Yu, letters, poetry talks and ci talks. The authors are famous scholars such as Chen Yinque, Meng Sen and Lu Qian. In the inaugural issue, Li Dingzhuo published eight works of political theory, ci poetry and poetic talk under the pseudonyms of Li Xingzha, Yi Mei and A Tong respectively, and in the second issue, nearly 20 articles of Li Dingzhuo were published. It can be seen that Integration magazine has become Li Dingzhuo’s own "mouthpiece" (when he founded the Chinese Society in Shanghai, he also used Sinology Newsletter as the mouthpiece). Two issues of Integration, with more than 20 articles, opened a door for a new understanding of Li Dingzhuo.


 


    Li Dinggan, editor-in-chief of Integration No.2.


 


    Li Dingzhuo’s most complete work is "The Record of the Scar of the Red Clouds", which is a learning record. On the right side of the cover of the book collected by the National Library of China, there is the words "courtesy of the author of the National Beiping Library", which should be written by Li Dinggan. The book "Origination" in front of the book said that it "didn’t have a good career and didn’t achieve fame", "I was deeply grateful for my teacher’s kindness, but I was disappointed and infinite", and "the articles of teachers’ Taoism were full of voices and smiles, but there were too many reporters", so it "sent the day as a text and cataloged it into a book", describing what the teacher inherited, and it was ". From primary school to university (especially the teachers in the eighth provincial middle school), the events of Mr. Ding Shanzhi, Yu Guiyan, Li Gengsheng, Zhuang Hongxuan, Ye Yigu, Dong Bodu, Liu Boming, Shen Shangqi, Du Zuoliang and Mei Disheng are recorded separately. At the end of the book, there are four appendices. Don’t remember the deeds of Wang Boqin (Winter Drink), Li Xiang (Trial Speech), Huang Kan (Ji Gang) and Master Hongyi.


 


    Li Ding is the author of "A Record of the Scar of Crimson Clouds"


 


    The back page of the cover of "The Record of the Scar of a Scar" is the catalogue of Li Dinggan’s works:

    When Li Dinggan wrote down these memories, most of the teachers had already passed away. Every time he read the teacher’s kindness, he was often disappointed and even shed tears, which led to the publication of such a moving learning record as "The Record of Crimson Scars". In the book "Mr. Zhuang’s Persuasion", Li Dinggan recalled that when he was a child, he studied with Mr. Zhuang Qichuan, and because he was "never working hard" and "stubborn and playful", he failed his teacher’s painstaking efforts and often felt guilty. As a result, I thought of the students I had taught, "Even though I saw my books from all my disciples, I forced them to take notes from my mouth to submit them. If they were as I like, the class would be only two or three people, which would make my heart ache inexplicably." I thought this was "the present report for my teacher." He fancied it, "I don’t know my students, but now there are university professors (such as Chen Dinghong), and their disciples can be as enthusiastic as their predecessors, and their disciples’ transcripts can also do their best." In "A Brief Introduction to the Purport of Integrated Compilation Society" (the first issue of Integration), when referring to the students who taught in Yangzhou Sinology Specialized School, he wrote proudly: "There are Cheng Yunqing, Fei Mingluan, He Minglong and Chen Hengpu."


 


    In the book "A Record of the Scar of a Crimson", the friendship between Li Dinggan and his teacher can be seen everywhere from time to time, and his style of being a man and studying is also revealed from time to time. "Mr. Li’s Loan for Gold" is about Li Gengsheng, who teaches in the eighth provincial middle school. When he heard that Li Dingji was "short of money, and he didn’t have enough room and board, and he didn’t feel enough", he asked the client to transfer ten gold. Unexpectedly, Li Gengsheng was later killed in the village by vendetta, and Li Dinggan was obsessed with Mr. Li’s loan, always trying to raise money to find opportunities to return his philosophical heirs. Later, I was transferred to the client, and my heart began to be a little safe. In "Mr. Li Shenyan’s Personal Experience", Li Dingji recalled Li Shenyan’s remarks about "leaving his relatives to be beautiful" and aroused his indignation at the plagiarists. "Literati’ painstaking efforts are condensed into articles, and ghosts and gods should be cared for, so that we can kill such thieves."


 


    There are many other words in the book, which can supplement the biography of scholars. For example, "Mr. Wang Dongyin’s Personal Experience" describes that when Wang Bokun was teaching Southeast University, he was "dressed in cloth, similar to Mr. Liu Yimou, and indifferent to elegance" and "what he taught was poetry and neo-Confucianism. For example, "The Book of Songs" also selects hundreds of poems from a literary perspective, "Mr. Wang is good at poetry and respects Lao Du". It is also mentioned that there were three Du Shi lecturers in Southeast University at that time, namely Hu Xiaoshi, Li Shenyan and Wang Boqin. Also remember the characteristics of their respective lectures: "Mr. Hu Xiaoshi likes to attach the words of the new school of rhetoricians, Mr. Li Shenyan takes the words of the Selected Works as evidence, and Mr. Du discusses poetry." "Mr. Huang Jigang’s kiss", Huang Kan to Southeast University to give lectures, Li Dinggan went to attend, "Mr. Sit established, enter the room, everyone is awed. And Mr. looks very ugly, dental caries sound Chu, not easy to distinguish. " Remember what he said, "I will continue to talk about the following letters in the stream group, and take the sentences in the Book of Songs as an example; Occasionally or slightly turn over the books, and at least what is written on the blackboard. However, a quiet and profound attitude is imperceptible and calm. "


 


    The Record of the Scar of the Red Clouds also recorded Li Dinggan’s opinions to many scholars at that time. Such as "Mr. Mei’s Papers", that is, Hu Shi had a fierce criticism:


 


    Gai Hu is a philosophy of life. In the United States, he caters to his countrymen, but when he returns home, he relies on the United States to respect himself. The loneliness of not being willing to teach is to put forward political opinions in Hard Weekly and Reading Magazine. Mr. Mei congratulated him by saying, "Mr. Mei is very good at talking about politics, which is better than advocating experimental philosophy and vernacular writing." Hu mouqiang has always explained himself with his studies. However, I think Hu Mou later worked in China College, and talked about his constitutional human rights in the magazines he edited. He was in cahoots with Luo Longji, but his knowledge of political science was really shallow, which was beyond Roche’s. When the national disaster broke out, the Anti-Japanese War broke out, and Hu was appointed as the ambassador to the United States with American Express, and Mr. Mei was also appointed as a political commissar with a professor from Zhejiang University. So far, the situation has changed, and Mr. Hu’s contribution to China is geometric, which is unknown to us, but we know that Americans love Hu Shi very much and despise Chinese in general! Whoo! Is it true that the ambassador is so unworthy?


 


    Except for two relatively complete works, A Brief Introduction to the Letters of the Khitan and A Record of the Scar of the Red Clouds, and dozens of articles scattered in newspapers and periodicals, most of the works listed on the back cover of the Record of the Scar of the Red Clouds are missing. From the order of these works, we can also see Li Dinggan’s emphasis on his own research results of Qidan characters. Seeing this catalogue of works, we can’t help asking, since Li Dinggan’s interests involve religion, translation, poetry and western learning, what is the opportunity to turn to the study of Qidan characters?


 


    According to LIU Feng-kun’s Life of Li Ding-gan and Study on the Fine Print of Qidan, Li Ding-gan first came into contact with the fine print of Qidan, and read the rubbings attached to the article Nine Kinds of Postscripts and Tails of Liao Monuments by Professor Meng Sen (History of Word Heart, 1868~1938). There are nine kinds of Liao Monuments, of which the eighth and ninth kinds are the eight. After reading it, Meng Sen recommended it to Sinology Quarterly, which was published in Volume III, No.4.


 


    According to Meng Sen’s "Postscript on the Credentials of Qidan", it is said that:


 


    After the discovery of Liao stele in Jehol, I only got a photocopy of its rubbings … Li Junxiaotong, eager to learn and ponder, touched his curiosity and love of the ancient times, and made books thousands of miles away, making up for ignorance. It is not only a textual research on the book tablet of Khitan in Jehol, but also an enlightenment. A few days later, it was integrated into "A Brief Introduction to the Letters of Qidan", and there are quite a few literal examples to be found. Taking the Khitan script as a script without books to read, if you get enough, you will have enough Khitan script.


 


    LIU Feng-ti’s account of Li Ding-gan’s study of the Khitan script coincides with Meng Sen’s postscript. Li Dinggan also talked about his experience in the study of Qidan characters in the preface to disgusting words (the first issue of Integration), which has a more detailed description:


 


    At the age of 18, I worked as a member of the National Compilation Museum, and the more I encouraged myself to learn. Shi Chengming ordered the translation of Shakespeare’s Textual Research Record, referring to hundreds of books, and taking its essence as a note. The rubbings in Qidan in Liao Mausoleum of Shire River were exhibited and transmitted to the National Peking University Institute. Scholars in France and Japan failed to distinguish its structural grammar. Yu Nai spent a few days first writing a tablet test, which was published in Sinology Quarterly, and then synthesized into a Brief Introduction to the Letters of Qidan, which was called the help of my mother for sixty years. My mother took Changji as a warning, so Mr. Meng Xinshi of Wujin gave a poem saying: "It shows the mysterious power, and it introduces the longevity words. I want to play with Nanya and talk about the North Hall. Turbid times are perverse, and the door is clear and filial. Nausea turns over the ring, and the hand is not exhausted. " Gai Documentary also. Yu Xuan resigned due to illness and went back to his hometown. What he learned all his life was forgotten for a while. After that, although he gradually recovered, his memory eventually lost.


    Li Ding wrote "A Brief Introduction to the Credentials of Qidan" (for Tsinghua University)


 


    According to Li Dinggan’s self-report, it was accidental that he turned to the study of Qidan characters. It was after he became an interpreter in the National Compilation Hall in 1933 that he was transferred to the Khitan script. We will be curious, in just a few days, how can Li Dinggan make a breakthrough in the interpretation and reading of strange Qidan characters?


 


    Li Ding-gan has a basic knowledge of elementary school. In "Mr. Huang Jigang’s Personal Notes", he once said that "Yu Zhi’s primary school was introduced from western comparative literature, which is similar to what Wang Zhou’s father said", but he did not take Huang Kan’s ancient sound theory for granted. Since then, he has taught Jiangdu County No.3 Middle School, and once wrote "On the Confusion of Ancient Phones", including a section devoted to Huang Kan’s ancient phonology. It can be seen that it is no accident that Li Dingji can make rapid achievements in the interpretation and reading of strange Qidan characters.


 


    In the preface to the language of disgusting words, "My mother admonishes me with long-term nausea", and this half sentence can also be seen that Li Dingji’s mother is a sensible person, not comparable to the vulgar village. Previously, we didn’t understand that Li was actually a "Yizheng clan". The article "Mr. Zhuang’s exhortation to learn" describes the literary influence of Zhuang Qichuan (word Hongxuan) on Li Dinggan when he was teaching in No.8 Middle School. Among them, an interesting thing is described in particular. Li Dingzhuo was gifted and intelligent, and Zhuang Qichuan was very fond of him. He specifically told him that "when he returned home after class, he should take supplementary reading materials, such as Records of Historical Records, and study them from time to time". Li Dinggan replied that he did not prepare this book. However, Mr. Zhuang said, "Otherwise, my son belongs to Yizheng clan, and there will be plenty of books. Why not have this book?" Then, when Li Dinggan got home, he asked his mother if there was this book in her home. Her mother took out six volumes of Zhu Mo’s overprinted Records of Historical Records from the bookcase. Li Dinggan said, "See the weekly review of his commentary, which enlightens people’s sanity and makes them forget their tiredness." Six volumes of Records of Historical Records will be finished that night. Through this incident, we can also see that, indeed, as Zhuang Hongxuan said, the Li family in Yizheng is a "clan" with a rich collection of books, and Li Dingzhuo is not without family origins.


 


    In order to outline Li Dinggan’s life experience in an all-round way, this paper, based on the original materials, such as Records of the Scar of the Red River and Integration (mainly, a Brief Introduction to the Purport of the Integration Compilation Society and a Preface to the Disgusting Language), refers to Li Dinggan’s Life and a Study on the Fine Print of Qidan, and the Interpretation of Qidan Literature.


    Li Dinggan, born on October 14th, 1907, whose name is Xiao Tong (also called Xiao Tong, Xiao Tong) and name is Xing Cha, and whose pen names are Chang Sheng, Yi Mei, A Tong, etc. (Preface to < Nausea >): "Fu Yu’s life is a text, and his signature is related to the topic, which is uncertain at first. On learning and politics, each is called the star hawthorn. Talk about trivial language, or be a smoker. And poetry rhymes, many memories of plum. " ), Yizheng, Jiangsu Province. When he was five or six years old, he entered Li primary and secondary school (the school was located in the teacher Wang Shu’s east home). Not long after, my father died.


 


    During his school days, Li Ding’s homework was excellent, and teachers often rewarded him. In the summer of 1916, after graduating from primary school, he entered the eighth provincial middle school. At that time, literature was divided into branches, and Li Dinggan was divided into real branches (that is, mathematical and physical branches) because he was still young. In Provincial No.8 Middle School, Li Dingzhuo was taught by Li Gengsheng, Zhuang Qichuan and Ye Weishan, which had a great influence on the later transfer of literature and history.


 


    Li Dinggan was good at arithmetic since childhood and devoted himself to mathematics, physics and engineering. In 1923, he was admitted to the National Southeast University. He planned to enter the Massachusetts Institute of Technology in the United States, traveled to Britain, France and Germany, and then returned to China to work. (Notes on Mr. Du’s Calculation, Notes on Mr. Ye’s Gift) After entering National Southeast University, I took the courses of "Introduction to Engineering" and "Introduction to Fire Prevention" in my first year as a preparatory course. In the first year, the courses offered were simple, but Li Dinggan was uninterested. A year later, the school closed engineering, and the professors of science resigned one after another. Li Dinggan had to be demoted to enter the arts and sciences, which gradually deviated from his initial willingness to take the exam. ("Mr. Ye’s Message")


 


    At that time, the National Southeast University followed the ideal of former American President Wilson, with arts and sciences as the center and agricultural and commercial education as the assistant. For this helpless choice, Li Dingzhuo "had to stay in the arts and sciences for a year until the next year’s division" ("Mr. Du Bu Shu Ji"), and took courses such as philosophy, western history, English literature history, word selection, and German, French and Japanese. When the school was divided into departments, there was no choice, so I switched to foreign languages. Li Ding-gan is selfish, still studying mathematics and physics, and taking advanced physics, calculus, probability and other courses. At this point, Li Dinggan’s expectation for himself in mathematics and physics is, "In the subject of mathematics, I am self-reliant and intelligent, and I have not made deep efforts. I thought that after that, I only wanted to understand the mathematical part of China’s old book, and it was enough "("Mr. Du Bu Shu Ji ").


 


    In 1927, after Li Dinggan graduated from National Southeast University, he worked as a teacher in Ren Zhongxue for many years. During this period, he and Lu Qian, Fan Cunzhong and others founded Di Lv Society to introduce western culture, enrich the content of Chinese studies, and made concerted efforts to translate the Encyclopedia Britannica. Later, when the revolutionary army arrived in Nanjing, the political situation changed, the school was reorganized and the members were scattered. In 1933, he was hired to compile by Nanjing National Compilation Museum, where there was a plan to translate The Complete Works of Shakespeare. During this period, Li Ding-gan undertook to translate Shakespeare’s Textual Research Record, referring to hundreds of books, taking its essence as a note, and the manuscript was destroyed by Japanese artillery fire. At this time, Li Dinggan read Meng Sen’s Nine Kinds of Postscripts on Liao Monuments, and began to contact the fine print materials of Qidan, and there were such publications as A Study on the Monument of the Khitan in Jehol and A Brief Introduction to the Khitan Letters, which led to the study of the Khitan characters. Later, due to encephalopathy, he helped to run Yangzhou Sinology Specialized School, taught Historical Records as a full-time teacher in Yangzhou, and opened three other subjects: modern literature, western literature and mathematics.


 


    In 1937, when his mother died, Li Ding-gan was in great pain, touching the hardships of his life and drawing on the door of conversion. Li Hongyi, a master, was recorded as a disciple and became a layman (No.1 and No.2 in Volume 6 of Sensibility, Li Xingcha’s Why I Believe in Buddhism). After the July 7th Incident, the National College was closed, and Li Ding returned to his hometown to avoid chaos and founded Wucheng College of Arts and Sciences. In the spring of 1941, he went to an isolated island in Shanghai, established the China Society, attached the China Institute, and founded the magazine Sinology Newsletter. After the fall of the island, he took his family to southern Anhui, still focusing on promoting Chinese studies and introducing western learning. During this period, Li Ding-gan taught in the middle school attached to Fudan University (moved to Jingxian County, Gannan) and Guangyi Middle School (Maolin Town, Jingxian County). He returned to Shanghai and set up the Compilation Society of Integration.


 


    In 1945, he served as the clerk of the Jiangsu Provincial High Court. In 1946, he served as a member of the Personnel Office of the Civil Affairs Department of Jiangsu Province (according to the "Notice for Printing" attached at the end of the book "The Record of the Scar of the Scar", the address was "Zhenjiang Civil Affairs Department"). In May, 1947, I printed a thousand copies of the book "A Record of the Scar of the Scar". In July of the same year, the first issue of Integration, edited by Li Dinggan, was published. In September of the same year, the second issue of Integration magazine was published. From the autumn of 1947 to the spring of 1948, he taught in Yangzhou Middle School, Jiangsu Province. In 1948, he served as the head of the fifth section of the third department of the Anti-smoking Committee of the Ministry of the Interior. In 1949, he went to Shanghai Wusong Middle School to teach.


 


    From the end of December, 1957 to the beginning of July, 1958, Li Dingji wrote back to the editorial department of Zhonghua Book Company for the publication of his manuscript "A New Comment on the Khitan Letters". At this time, Li Dingzhuo has been involved in the study of Qidan characters for more than twenty years. According to the letter from the Personnel Section of Shanghai Editorial Institute of Zhonghua Book Company, Li Dinggan was removed from Wusong Middle School because of "political problems". It is also said that the government found out that Li Dingzhuo was a military spy and was arrested in April 1958. On December 15th, 1958, he was sentenced to 15 years’ imprisonment by Shanghai Baoshan People’s Court and detained in Shanghai Tilanqiao Prison. In the spring of 1959, he was transferred to Yeshan Mining Area, Shun ‘an Town, Tongling City, Anhui Province to serve his sentence. In July of the same year, he wrote to his family and transferred to Jitoushan Mining Area in Shun ‘an Town to serve his sentence. In August of the same year, the family sent a parcel and it was returned on the grounds that there was no such person. Since then, the whereabouts are unknown.


 


    He is the author of a new account of the Khitan credentials, a textual research on Shakespeare (translated), a history of traffic between China and Europe (translated), a record of the shadow of the crimson owl, three major problems in material construction, and a record of faithfulness in the catastrophe. There is a collection of poems "You You Yin", a collection of words "Yi Mei Ci" and a collection of essays "Disgusting Words". There are also works on phonology, poetry and ci, which are scattered in newspapers and periodicals.


 


    Restoring Li Dingzhuo’s legendary but unfortunate life makes us feel more deeply. Li Dingzhuo was originally devoted to mathematics and physics, and he had the ambition to go to Massachusetts Institute of Technology for further study and study in Britain, France and Germany before returning to China to work. However, fate seems to be playing tricks on him from the beginning. At first, the National Southeast University stopped offering engineering courses, which made him deviate from his original intention. In desperation, he turned to foreign languages and studied Chinese from famous teachers. At that time, Li Dingji didn’t know that there was a more severe test waiting for him.


 


    After Li Ding entered the National Compilation Museum, he was entrusted with the translation of Shakespeare’s Textual Research, but the translation was taken care of and destroyed by Japanese artillery fire. He occasionally touched the Liao stele and came to the club, but the Qidan characters were actually interpreted, and then he was immersed in it for 20 years, which became a grand view. Unexpectedly, when he was trying to win the publishing opportunity for the manuscript, the disaster suddenly came. I couldn’t help myself, and the manuscript also dispersed. During that time when the literature was blank, he should be able to pray secretly. Praying for ghosts and gods can also protect the new theory of Qidan credentials, which condensed his efforts for more than 20 years.


 


    If Li Ding has knowledge under the spring, it will be gratifying to know that half a century later, people still remember him, and remember his figure when the field of Qidan writing research was a wild hazel. However, he has set foot in so many fields, and those words full of talents are not good. He probably didn’t expect that when he was really rejected and forgotten by the world, no one would ever write a tearful account of his personality and his wonderful knowledge like he did when he wrote A Record of the Scar of Crimson.


 

Double 11 is a little "cold"? Don’t sing down yet.

  Big data shows that 15-year-old "double 11" is a bit "cold".

  According to Baidu Index, the search index of "double 11" was on the rise from 2011 to 2015, and it basically maintained its popularity in 2016, but it dropped significantly in 2017, only slightly rising in 2019, when live e-commerce rose, and then falling all the way, making 2022 the coldest "double 11" in the past 10 years. It should be said that this year’s "double 11" heat is slightly higher than last year, but judging from the trend, its highlight moment has passed.

Double 11 is a little "cold"? Don't sing down yet.

  From the outside, after the rise of live e-commerce and social e-commerce, strategies such as anchor welfare and 10 billion subsidies have made low prices run through the year. Statistics show that two-thirds of Tmall’s days in a year are shopping festivals, and consumers have long been "desensitized" to big promotions; From the inside, the negative impression of false promotions such as raising prices first and then lowering prices, and getting together for half a day is only one yuan and eighty cents cheaper, has killed consumers’ passion and trust in big promotion. If we catch up with some consumers who are not well off, it will inevitably get cold.

  However, this does not mean that "double 11" is completely cold. Besides big data, there is another hot "double 11"-

  There are more and more participants. This year, JD.COM Live and Xiaohongshu e-commerce have entered the market, and the record is good. Take Xiaohongshu as an example. During the "double 11" period, the number of e-commerce orders of Xiaohongshu was 3.8 times that of the same period of last year, and the amount of powder broadcast in stores was 14.2 times that of the same period of last year.

  The value brought to businesses is becoming more and more accurate. Take Tmall as an example. As of 0: 00 on November 11th, Taobao Tmall has brought more than 100 million new members to merchants, and the turnover of 38,000 brands has increased by more than 100% year-on-year.

  Some consumers don’t pay attention on the surface, but their actions are sincere. According to the data of the State Post Bureau, from November 1 to 11, the national postal express delivery enterprises collected 5.264 billion express parcels, a year-on-year increase of 23.22%.

  The figures show that "double 11" is still the most important outbreak period of various brands in a year, and it is the training ground with the most concentrated infrastructure such as supply chain, cloud service and logistics. Today’s "double 11" peak may be the norm in the future. "double 11" has been transformed into a "concern war" and a "value war". Every November, people always think about whether to buy something. For this reason, "double 11" should not be underestimated.

Double 11 is a little "cold"? Don't sing down yet.

  Among all the data, there is a set of data that deserves special attention: this year, in double 11, there are 1,606 new brands that have opened stores in Tmall for less than three years, winning the champion of new trend category, which means that as long as consumers are treated with care, there will be a lot of market opportunities. In Xiaohongshu, there are also 30 brands located in the new track, and their products cover furniture, accessories, bags, new Chinese clothes and so on. Tracks are constantly emerging and brands are changing rapidly. Such a market is full of vitality and the competition is extremely fierce.

  However, no matter how difficult it is, there is still a chance. Apart from China, it is hard to imagine any other market that can breed so many new brands in a short time. This is the resilience of China’s economy, and it is also the strength of a consumer market with a population of more than 1.4 billion.

  There’s no need to talk bad about "double 11" now. Even at the end of the attention cycle, there is a long tail effect.

  How "double 11" behaves next depends on itself. This year, the General Administration of Market Supervision once again issued the "double 11" Guide to Promoting Compliance, emphasizing nine aspects, such as eliminating price fraud, strengthening advertising review, preventing counterfeiting and resolving consumer disputes, which can be called the "longevity guide" of "double 11". "double 11" should be able to accompany consumers in China for several years if we can listen to users’ voices, resolutely implement regulatory regulations and firmly guarantee quality services.
