　　Promoting the creative transformation and innovative development of Chinese excellent traditional culture, better constructing China spirit, China value and Chinese strength, and providing spiritual guidance for the people are the requirements put forward in the report of the 19th National Congress for the whole party to deeply understand and implement the spiritual essence and rich connotation of Socialism with Chinese characteristics Thought in the new era. As for TV variety shows, in recent years, under the policy control of the State Administration of Press, Publication, Radio, Film and Television with the development direction of "commonweal, culture and originality", the number of entertainment programs with copyright such as singing and talent shows has been greatly reduced, and the proportion of cultural independent original programs with China characteristics has been increasing day by day. It has become a common practice to promote the transformation and development of excellent traditional culture in the form of images, which has made a useful demonstration in the cultural field.

　　In the spring of 2017, the second season of the Chinese Poetry Conference, the Reader and other cultural programs were launched one after another, and the screens were popular, which not only attracted high ratings and attention, but also won rave reviews from the audience. Many industry experts came to the conclusion that "the spring of cultural programs has arrived". As a result, major TV stations and producers have boarded the development express train "bound for spring" and launched works such as I am an orator, Chinese characters, traveling thousands of miles, Chinese restaurant and Chinese series. At the same time, the popularity of cultural programs is also rising. The first stage of the network variety "The Speaker" has a total broadcast volume of 590 million; Hunan Satellite TV’s "Chinese Restaurant" has been the number one viewing champion for 11 consecutive issues, and the cumulative network broadcast volume has exceeded 2.6 billion; The first program of "Cheer for China" by Oriental TV reached an average audience rating of 0.74% in 35 cities nationwide, with 128 million TV viewers, setting a national audience rating record for traditional Chinese opera and cultural programs in the past three years … … To explore the reasons for the recent popularity of cultural programs and the ratings of Qi Fei, the main reason lies in the creators’ continuous transformation and upgrading to adapt to the changes in the market environment on the basis of cultivating the fertile soil of traditional cultural resources, so that the quality of works is steadily improved, and generate is full of vitality.

　　Creative innovation "deeply cultivates and broadens" traditional culture

　　For a long time in the past, the phenomenon of serious homogenization of cultural programs in China has been criticized by the industry. After the quiz show "Lucky 52" and "Happy Dictionary" became popular on the screen, a number of works with similar forms swarmed in. When "Lecture Room" was a smash hit, similar "lecture" programs rushed to the beach market … … The cluster broadcast of the same type of programs not only makes the audience feel aesthetic fatigue, but also makes the creation fall into a narrow lane of thinking. Happily, this problem has been significantly improved in the past two years. Cultural programs have achieved breakthroughs in the expansion of theme styles, the excavation of cultural connotations and the innovation of production concepts, and gradually entered the 2.0 era.

　　China’s traditional culture not only contains many outstanding core ideas and concepts, such as caring, honesty and justice, but also contains rich and complex ancient myths, classic ancient books and literary works. These classic cultural treasures, which often appear in textbooks and books, are like spring snow, giving people a feeling of "high cold", which inevitably makes TV audiences who mainly appeal to entertainment, release pressure and enrich their spare time feel dull and obscure. In order to make the program grounded and popular, the creators try to use all kinds of trendy and fashionable expressions and image languages that young people can understand. For example, The Book of Poetry by Oriental TV breaks through the inherent competition form of general educational culture programs, takes "Poetry into the homes of ordinary people" as the core idea, and pays attention to the flexible use of poetry in life; Anhui tv’s folk song competition program "China in My Ear" not only reproduces the classic melody of traditional folk songs to awaken the national memory infiltrated in the blood of Chinese people, but also innovatively incorporates modern elements, presenting popular style "Under the Silver Moonlight" and rock singing "I Love You, Snow in the North of Saibei" to show the enterprising spirit of young singers.

　　From learning Chinese characters together, reciting poems, busy dictation and holding competitions, to promoting reading, paying attention to folk songs, focusing on food and propagating family style, cultural programs have also jumped out of the old pattern that it is difficult to have new ideas, and are no longer confined to the competitions of poems and songs, but have opened up many humanistic themes focusing on urban scenery, food, opera and other fields. "Charming China City" by CCTV Financial Channel turned its creative vision to urban culture, and adopted a two-pronged model of "culture+tourism" to dig deep into the rich connotation and unique charm of the city. The Chinese Restaurant, which was recently broadcasted on Hunan Satellite TV, takes the story of Chinese opening a Chinese restaurant in a foreign country as the framework, which runs through the clues of spreading Chinese food culture and shows the confidence and tolerance of China’s traditional food culture.

　　Sincere feelings make the program "high but not cold"

　　High-value programs should not only temporarily attract the audience’s attention with novel forms, but also make them watch, think positively and discuss enthusiastically, infect and inspire people and guide the way forward. Therefore, while thinking about how to improve the expression form of the program, producers try to realize the transmission of "internal" value through this "external" change. Dong Qing, the producer of The Reader, said: "We construct the reader’s personal life experience through conversation. When the speaker and the listener have the same mind and the emotion reaches a certain saturation, the text comes out with the trend. The guests were restored to the appearance of sincere readers on the stage, at ‘ I want to read ’ Not ‘ I can read ’ In the active expression of, complete ‘ Asking about life in the name of literature ’ The mission. "

　　In the case that the trend of variety show "fighting for star lineup" has been widely criticized by the industry, many creators of cultural programs do the opposite, emphasizing "civilian consciousness" and paying attention to the interaction between their works and people from all walks of life. As a result, more and more topics are concerned about the fate and feelings of ordinary people and reflect the great practice of people’s production and life, making cultural programs more zeitgeist and practical significance. For example, Hunan Satellite TV’s "A Thousand Miles of Children" uses documentary shooting, interviews with people and other methods to visually and vividly present the family letters and the ordinary stories between parents and children behind them, showing the good family style of ordinary people. In "I am an orator" by Beijing Satellite TV, ordinary people from different educational backgrounds, different regions and different industries tell their life experiences in front of the audience: the courier still does not give up his dream after hard work, the soldier excitedly tells his mission, the Harvard girl tells us with personal experience that "the country is strong and the teenager is strong", and the network anchor is named "Shoumai" … … The presentation of these "amateurs" diverse attitudes towards life can not only help different audiences to find the content that is in line with their own ideas, thus generating emotional resonance, but also demonstrate the upward attitude towards life and deep feelings of home and country in contemporary Chinese.

　　A variety of paths make excellent culture "spread properly"

　　Internet instant messaging, two-way interaction, mass storage and other characteristics bring not only the optimization and upgrading of content production and the change of audience interaction mode, but also the expansion of communication pattern, the increase of communication channels and the change of communication mode to TV programs. In this case of drastic changes in the communication ecology, producers should keep pace with the times and actively adjust their propaganda ideas in order to obtain a wider audience and a stronger audience stickiness, and realize the geometric expansion of the influence and communication power of cultural programs through "two micro-ends" propaganda matrix, network synchronous live broadcast and other ways.

　　Zhejiang Satellite TV’s "Chinese Characters" has produced several short video programs "Test Your Word", and each video has tens of millions of clicks and forwards; "Cheering China" pushed the talent performance of "cheering people" to major social platforms in the form of video, which quickly attracted the attention of netizens. Many producers have grasped the characteristics of fragmentation, mobility, event and socialization of new media, and spread program information such as stories, quotations and cartoon images of participating guests to online communities, amplifying their news value and forming a "cultural phenomenon".

　　In the era of media convergence, cultural programs should also learn to integrate the resources of big screen and small screen, open up the two lines of online and offline, and build a communication framework of all-media interaction. "The Speaker" pioneered the platform mobile live broadcast. The bus of the program group was broadcast live in five cities across the country. Players can wave to get on the bus at any time, and the winners stay and the losers get off, which greatly improved the public participation. "Cheer for China" cooperated with the "Everyday P Picture" APP to launch the "Drama Face Changing" activity, which received 2.4 million reposts in four days. These innovative methods not only make the existing cultural programs go to the public, but also incite the market demand for more high-quality programs with cultural nourishment and value resonance functions, and realize the creative transformation and innovative development of Chinese excellent traditional culture.

　　BEIJING, Beijing, March 17th (Xinhua)-Work is "lying flat", "eating heart" does not change, alcohol addiction is hard to stop, people are keen on organizing games, and playing cards to slap eggs … …

　　A few days ago, the Supervision Committee of the Commission for Discipline Inspection of Xuancheng City, Anhui Province issued the "Announcement on Accepting Complaints and Reports on Outstanding Cadres’ Work Style in the City", and the above behaviors were all within the scope of reporting.

　　The problem of "six heavy and six light" can be reported.

　　The outstanding problems of cadres’ work style accepted by Xuancheng this time are focused on the "six stresses and six despises" in environmental work for the people and enterprises: the problem of emphasizing form over content, the problem of emphasizing process over results, the problem of emphasizing procedure over effectiveness, the problem of emphasizing overweight over burden reduction, the problem of emphasizing achievements over potential achievements, and the problem of emphasizing pleasure over struggle.

　　For example, we should pay more attention to form than content, implement the decision-making and deployment of superiors, pretend to engage in form, mechanically implement policy measures and work arrangements, copy them, serve the masses well, look good, and do difficult things.

　　Emphasis on achievements over potential achievements, biased view of achievements, disrespect for objective reality and the needs of the masses, arbitrary decision-making, blind decision-making, illegal decision-making, superficial articles, image projects, keen on piling bonsai, creating bright spots, and ostentation and extravagance.

　　Pay more attention to pleasure than struggle, work lightly, be afraid of hardship and tiredness, be a "lying-flat" cadre, pursue extravagant enjoyment, "eat your heart", be addicted to alcohol, be keen on organizing games to drink, play cards and slap your eggs, and even take advantage of your position to eat and get cards.

　　In the reporting methods announced by Xuancheng City, in addition to the letter address and telephone number, there are also websites and new media channels. The announcement also includes a QR code for reporting WeChat.

　　Open more reports, engage in appraisal, and rectify the style of cadres

　　In response to the problem of cadres’ work style, in recent years, many channels for reporting by the masses have been opened.

　　In June last year, Wolong District, Nanyang City, Henan Province issued an announcement to collect clues about the problem of "lying cadres" in all units in the region.

　　The collection of clues for "lying cadres" includes 10 aspects, such as "muddling through work and being satisfied with meeting" and "‘ Statement ’ After that, nothing ‘ Performance ’ , serving the masses depends on ‘ Performance ’ " "I don’t say anything at ordinary times, I don’t know anything", and so on.

　　Last year, Hanshou County, Hunan Province launched a public image evaluation activity for cadres. According to the main image of cadres at work, the evaluation content was divided into four types: "practical, chatting, making trouble and lying flat".

　　For example, cadres who dare to take responsibility, be conscientious and achieve remarkable results are practical; The cadres who are "idle, sit and talk, tell others what to do, have a low eye, make a good statement, implement it poorly, and talk about people behind their backs" are chatty; Cadres who "don’t talk about politics, talk nonsense that they shouldn’t, buck-passing, and disobey" are mischievous; Cadres who "have low work standards, are not enterprising, muddle along, have no motivation, are helpless and let nature take its course" are lying flat.

　　In Guizhou, the Commission for Discipline Inspection and Supervision of Honghuagang District, Zunyi and the Business Environment Bureau of the Joint District also set up the "Snail Award", which included procrastination, perfunctory responsibilities, disregard for the interests of the masses, and ineffective rectification of problems, and awarded the "Snail Award" in the form of monthly assessment and quarterly awards.

　　Let cadres who muddle along and do nothing have no market.

　　In this year’s Spring Festival Evening sketch "Pit", the "lying cadres" portrayed by actor Shen Teng became a hot topic for a while.

　　According to the commentary published on the website of the State Supervision Commission of the Central Commission for Discipline Inspection, the treatment of "lying cadres" requires the right medicine and multiple measures. One of the most important aspects is to establish and improve a scientific mechanism for selecting and employing people, encourage them to take responsibility, identify, select and make good use of cadres, resolutely say no to "lying cadres", firmly applaud those responsible, and select "aggressive" and "dry" to avoid.

　　Zhu Lijia, a professor at the Central Party School (National School of Administration), told the reporter of Zhongxin. com that there is no market for cadres who lie flat and do nothing. The starting point of exploration in some places is worthy of recognition. However, the more important task is to improve the performance evaluation mechanism of cadres and consolidate long-term supervision.

　　Experts said that we should explore the establishment of a "negative list" of work style problems, standardize and program the daily cadre supervision system, strengthen performance evaluation and social supervision, and look at achievements, effects and word of mouth, so that cadres can’t "lie flat" or dare to "lie flat".

　　Guangming net news Since the beginning of this year, large language models such as ChatGPT and ERNIE Bot have been popular, and the question of whether artificial intelligence (AI) can surpass human beings has aroused heated discussion. On May 29th, the "2023 China Computing Power Development Seminar" organized by China Intelligent Computing Industry Alliance was held in the Institute of Computing Technology, Chinese Academy of Sciences. The theme of this seminar is the opportunities and challenges of computing power under ChatGPT, which brings together many authoritative experts and scholars in the industry to conduct in-depth exchanges and discussions from multiple dimensions such as technology and ecology, determine the development trend of the liquidation power industry, and give countermeasures for the current artificial intelligence infrastructure and computing power service construction.

　　At the seminar, Chen Runsheng, an academician of China Academy of Sciences, said that the development of artificial intelligence is unstoppable by human beings, which is the essence of scientific development. At the same time, he pointed out that the phenomena of "Breakthrough" and "Grokking" in the big language model deserve our consideration.

　　What is "emergence"? A complex system is made up of many tiny individuals, who come together and interact with each other. When the number is large enough, it shows a special phenomenon that can’t be explained by micro-individuals, which is called "emergence". Chen Runsheng vividly explained, "I gave it (the big model) a lot of learning data, and as a result, there will be something in its answer that is not in the learning data. This phenomenon is called emergence." The calculation of a large model shows that when the training data is large (for example, more than 100 billion), there will be an emergence phenomenon, and this phenomenon will not occur when the scale is small.

　　What needs to be clear is that the emerging phenomenon is controversial in the scientific community at present. For example, a professor at Stanford University thinks this is a metric problem, which involves measurement, basic physical coordinate system and so on.

　　"Emergence in the process of natural language processing due to the rapid increase of the whole computation is a new problem, which is worth considering," Chen Runsheng said.

　　What is an epiphany? Chen Runsheng explained, "In the process of training a neural network, you don’t understand it once, twice, the fourth time, and the fifth time. Just like a child learning something, you don’t understand it once or twice, and you suddenly learn it after teaching N+1 times."

　　He believes that this is a model of human brain learning, "learning to understand at a certain time", "computers can’t have epiphany, but large models will have epiphany."

　　Not long ago, Claude, one of ChatGPT’s main competitors, expanded the number of tokens in the context window to 100,000, equivalent to 75,000 words, which greatly exceeded the 8192 tokens in the context window of GPT-4. This means that users can upload up to 500 pages of documents to Claude, which can understand and digest the information in less than 1 minute and answer users’ questions based on the uploaded information.

　　Claude was launched by Anthropic, a company founded by former OpenAI employees. Since the end of 2022, Google has invested nearly $400 million in the company.

　　In this regard, Chen Runsheng believes that the current learning speed of large models is much faster than we thought. "These two companies (OpenAI and Anthropic) are catching up with each other. Maybe after a while, GPT-5 will be stronger than Claude, and it will develop so fast that people will not catch up in the future."

　　"What’s more troublesome is that these big model companies are considering manipulating third-party equipment," Chen Runsheng said. "Being able to manipulate third-party equipment is a worrying thing. If you manipulate things related to safety and national defense, it will be terrible."

　　Chen Runsheng admits that the structure of human neural network is much more complicated than the current big model, and the development of artificial intelligence still has a long way to go. "The current (artificial intelligence) neural network should have revolutionary changes in the spatial structure model. Maybe at that time, (AI) can really surpass human intelligence."

The 19th National Congress of the Communist Party of China clearly made an important judgment that "Socialism with Chinese characteristics has entered a new era", and made a new summary of the changes in the main social contradictions in our country in the new era-"The main social contradictions in our country have been transformed into the contradictions between the people’s growing needs for a better life and the unbalanced development". This is our party’s new summary of the main social contradictions in Socialism with Chinese characteristics in the new era according to the changes of the times and national conditions. At the same time, it also emphasizes that the basic national conditions that China is still in the primary stage of socialism for a long time have not changed, and China’s international status as the largest developing country in the world has not changed. The whole party should firmly grasp the basic national conditions of the primary stage of socialism and firmly base itself on the greatest reality of the primary stage of socialism.

The Communist Party of China (CPC)’s understanding of the main social contradictions in our country is gradually deepened and continuously developed with the different historical periods and stages of social development in our country. The Party’s correct understanding and grasp of the main social contradictions in China is an important prerequisite for our Party to scientifically judge the national situation and correctly formulate major policies, and it is of great theoretical and practical significance for leading the whole Party and the people of the whole country to promote the development of China’s revolution, construction and reform.

1. The party’s understanding of the main social contradictions during the new-democratic revolution.

After the founding of the Communist Party of China (CPC), China society faced various complicated social contradictions. Since the Opium War, China began to fall into a dark situation of internal troubles and foreign invasion. The imperialist countries carved up their spheres of influence in China, and the feudal landlord class cruelly oppressed the peasants. The bourgeoisie colluded with imperialism, and at the same time, they were intertwined with the feudal landlord class to jointly oppress the working masses, and the mountains and rivers were broken, making the people miserable. In this grim situation, how to correctly understand and grasp the main social contradictions in China and formulate practical policies and measures accordingly? Guided by Marxism, the Communist Party of China (CPC) made a profound understanding and summary of China’s national conditions, especially the main social contradictions. After a long period of exploration, the Communist Party of China (CPC) people, represented by Comrade Mao Zedong, came to the conclusion: "The contradiction between imperialism and the Chinese nation, feudalism and the masses of the people are the main contradictions in modern China society." "The contradiction between imperialism and the Chinese nation is the most important contradiction among all kinds of contradictions." It was based on a correct understanding of the principal contradictions at that time that our Party scientifically formulated the line, principles and policies of the new-democratic revolution in different periods, United and led the people of the whole country through arduous and unremitting struggle, and finally overthrew the three mountains that were pressing on the people of China and won the great victory of the new-democratic revolution.

2. The Party’s understanding of the main social contradictions during the period of socialist transformation and construction.

After the founding of New China, what are the main contradictions in our society? The earliest summary of the main social contradictions in China after the founding of New China was the enlarged meeting of the Political Bureau of the Central Committee held by the CPC Central Committee in Xibaipo from September 8 to 13, 1948, namely the "September Meeting" in the Political Bureau of the Central Committee. In an important speech delivered at this meeting, Mao Zedong pointed out: "After the bourgeois democratic revolution is completed, the main contradiction within China is the contradiction between the proletariat and the bourgeoisie, and the external contradiction is the contradiction with imperialism." Liu Shaoqi also pointed out at this meeting: "In the new democratic economy, the basic contradiction is the contradiction between capitalism (capitalists and rich peasants) and socialism. After the victory of the anti-imperialist and anti-feudal revolution, this is the main contradiction in the new society. " He particularly emphasized: "We should clearly see this contradiction. This struggle between the proletariat and the bourgeoisie is a struggle between socialism and capitalism. " This is the first time that the leaders of our party discussed the main social contradictions in China after the founding of New China.

In the early days of the founding of New China, there were many economic sectors in China. "At that time, the main contradiction in rural areas was the contradiction between feudalism and democracy, not the contradiction between capitalism and socialism, so it took two to three years to implement land reform in rural areas." "After the victory of the new-democratic revolution and the completion of the land system reform in the whole country, the main domestic contradictions have turned into contradictions between the working class and the bourgeoisie, and between the socialist road and the capitalist road." On this basis, our party has formulated the general line of "transition period", that is, to gradually realize the socialist industrialization of the country and the socialist transformation of agriculture, rival industries and capitalist industry and commerce in a fairly long period of time. This task was basically completed by the end of 1956.

With the successful completion of socialist transformation, China society has realized the transformation from a new democratic society to a socialist society. From September 15th to 27th, 1956, the Eighth National Congress of communist party was held in Beijing. The Eighth National Congress of the Communist Party of China correctly analyzed the changes of class relations and major domestic contradictions in China after the socialist transformation was basically completed, and clearly pointed out that after the socialist transformation was basically completed in China, "the major domestic contradiction is already the contradiction between the people’s demand for establishing an advanced industrial country and the reality of a backward agricultural country, and the contradiction between the people’s need for rapid economic and cultural development and the current situation that economic and cultural cannot meet the people’s needs." The essence of this contradiction is the contradiction between the advanced socialist system and the backward social production when the socialist system in China has been established. The solution to this contradiction is to develop social productive forces and implement large-scale economic construction. For the first time, the Eighth National Congress of the Communist Party of China systematically summarized the main social contradictions in China during the period of socialist construction.

On February 27th, 1957, Mao Zedong delivered an important speech on Correctly Handling Contradictions among the People at the 11th (enlarged) meeting of the Supreme State Council, which was revised and supplemented and published in People’s Daily on June 19th of that year. In this important speech, Mao Zedong systematically discussed the Marxist theory of contradiction, pointing out that the basic contradiction in socialist society is still the contradiction between productive forces and relations of production, economic base and superstructure. At the same time, there are two different kinds of social contradictions in socialist society, namely, the contradiction between ourselves and the enemy and the contradictions among the people, which are completely different in nature. The former is antagonistic in nature, so it is necessary to adopt compulsory and dictatorship methods to solve it, while the latter is non-antagonistic, so it can only be democratic and educational. Mao Zedong also proposed that correctly handling contradictions among the people should be the theme of the country’s political life. Generally speaking, our party’s understanding of the main social contradictions in this period is correct and realistic. Later, due to some "Left" tendencies in the Party, the Party’s understanding of the main social contradictions was biased. On October 9, 1957, the Third Plenary Session of the Eighth Central Committee of the Communist Party of China put forward the conclusion that "the contradiction between the proletariat and the bourgeoisie, the contradiction between the socialist road and the capitalist road" is the main contradiction in our society at present; The second meeting of the Eighth National Congress of the Communist Party of China held in May 1958 proposed that before the socialist society was built, the struggle between the proletariat and the bourgeoisie, the struggle between the socialist road and the capitalist road,It has always been the main contradiction within our country. The party’s mistakes in understanding the main contradictions in the socialist period led to a series of major policy and decision-making mistakes of our party and state.

3. The Party’s understanding of major social contradictions during the period of reform, opening up and socialist modernization.

The Third Plenary Session of the Eleventh Central Committee of the Communist Party of China held in 1978 opened a new era of China’s reform, opening up and socialist modernization. On March 30, 1979, at the retreat of the Party’s theoretical work, Deng Xiaoping, the chief architect of reform and opening up, made an important exposition on the basic contradictions and main contradictions in socialist society. He pointed out: "The basic contradictions are still the contradictions between the relations of production and productivity, and the contradictions between the superstructure and the economic base." "As for what is the main contradiction at present, that is, the main problems or central tasks that the whole Party and the people must solve at present, because the Third Plenary Session decided to shift the focus of work to socialist modernization. Our productivity development level is very low, which is far from meeting the needs of the people and the country. This is the main contradiction in our current period, and solving this main contradiction is our central task. "

It is on the basis of the above explanation that the Resolution on Several Historical Issues of the Party since the Founding of the People’s Republic of China, adopted at the Sixth Plenary Session of the Eleventh Central Committee of the Party on June 27th, 1981, fully affirmed the formulation of the Party’s Eighth Congress and further streamlined and refined it: "The main contradiction to be solved in China is the contradiction between the people’s growing material and cultural needs and backward social production. The focus of the work of the party and the state must shift to socialist modernization centered on economic construction, greatly develop social productive forces, and gradually improve people’s material and cultural life on this basis. " This generalization has become an important basis for the party to formulate various lines, principles and policies in the process of reform, opening up and socialist modernization.

4. Socialism with Chinese characteristics entered a new era, the party’s understanding of the main social contradictions.

After long-term efforts, Socialism with Chinese characteristics has entered a new era, which is a new historical orientation for China’s development. Socialism with Chinese characteristics’s entry into a new era indicates that the principal contradiction in our society has also undergone new changes. The 19th National Congress of the Communist Party of China made a new summary of the main social contradictions in China in the new era of Socialism with Chinese characteristics. General Secretary of the Supreme Leader pointed out in the report of the 19th National Congress: "Socialism with Chinese characteristics has entered a new era, and the main contradiction in our society has been transformed into the contradiction between the people’s growing need for a better life and the unbalanced development." The report of the 19th National Congress of the Communist Party of China also summarized the reasons for the changes in the main social contradictions in our country: China has stably solved the problem of food and clothing for more than one billion people, achieved a well-off society on the whole, and will soon build a well-off society in an all-round way. People’s needs for a better life are increasingly extensive, which not only puts forward higher requirements for material and cultural life, but also demands for democracy, rule of law, fairness, justice, security and environment are increasing day by day. At the same time, the level of China’s social productive forces has improved significantly on the whole, and the social productive capacity has entered the forefront of the world in many aspects. The more prominent problem is the insufficient development imbalance, which has become the main constraint to meet the people’s growing needs for a better life.

The major social contradiction change in our country is a historic change related to the overall situation of Socialism with Chinese characteristics’s construction. This change requires us to focus on solving the problem of unbalanced and insufficient development on the basis of continuing to promote development and better meet the people’s growing needs in economy, politics, culture, society and ecology. Of course, at the same time, we must also see that the changes in the main contradictions in our society have not changed our judgment on the historical stage of socialism in China, the basic national conditions that China is still in the primary stage of socialism and its international status as the largest developing country in the world has not changed.

In a word, the Communist Party of China (CPC)’s understanding of the principal social contradictions in our country keeps pace with the times with the development of the times and the specific changes of China’s national conditions. The process of deepening the Party’s understanding of the principal social contradictions in our country marks that our Party’s understanding of the laws governing the development of human society and socialist construction has reached a new level, which is the new development of Marxist theory of contradictions and the new development of Marxism in China.

　　　　A volunteer couldn’t bear to leave the giant panda and cried with the keeper.

　
Many citizens saw the giant panda off.

　
The staff carried the weighed panda onto a special transport vehicle.

　
After the quarantine, the panda gets bamboo shoots as a snack.

　　　　At 12: 45 yesterday, eight Olympic giant pandas who had lived in Beijing for nearly 10 months set foot on their journey back to Sichuan, and tens of thousands of tourists went to see them off. Volunteers who used to be commentators at the Olympic Panda Pavilion cried and said goodbye to the panda babies.

　　　　At about 11 o’clock last night, the giant pandas finally arrived at the Bifengxia base in Ya ‘an, China Conservation Giant Panda Research Center by plane and car. They are in good physical and mental condition and are sent to the animal house to rest.

　　　　　　82-year-old man came to see me off.

　　　　"Is the Olympic panda gone?" At 8 o’clock yesterday morning, hundreds of tourists gathered outside the giant panda hall of Beijing Zoo, all of whom were very concerned about the situation of giant pandas. The staff of the Panda Pavilion kept explaining that eight Olympic giant pandas were still on display as usual.

　　　　In the Olympic Panda Pavilion, eight giant pandas are playing or eating bamboo in their respective activity areas, enjoying themselves. Good sisters "Duoduo" and "Cuicui" snuggled up in the corner of the playground, "Huanhuan" and "Taotao" hugged and wrestled, and "Fuwa" lay on the ground with bamboo on all fours. Tourists took out their cameras and took photos with the little ones.

　　　　"I came here early in the morning just to see the giant panda for the last time." Grandma Wang, 82, lives in Fengtai District and took a bus to the zoo to bid farewell to the Olympic panda.

　　　　At 9 o’clock in the morning, on the stage on the west side of the Giant Panda Pavilion, more than 20 children from Yinhe Youth Art Troupe sang "Love is the Most Beautiful": "panda,panda, I love you …" The immature singing attracted many tourists’ attention.

　　　　At the short farewell ceremony held in Beijing Zoo, China Research Center for the Protection of Giant Panda presented Wolong soil and Minjiang River water to Beijing Park Management Center. A "national treasure map" with 13 panda cubs born after the earthquake and the palm print of the panda cubs were presented to Beijing Zoo, and the naming right of one of the cubs was given to Beijing. After collecting the names of cubs from the public, Beijing Zoo was finally named "Olympic Games".

　　　　Yang Changjiang, a breeder, said that in order to "lure" giant pandas into cages, they were only given half a breakfast. In the morning, the breeder has cleaned the Olympic Panda Pavilion and disinfected the cages for transporting giant pandas.

　　　　　The greedy cat "Meixin" was first caged.

　　　　In the morning, more than 10,000 people went to the zoo to bid farewell to the Olympic pandas. At 10 o’clock, after the Olympic Panda exhibition, many tourists gathered around the truck carrying the panda. Many children ride around their father’s neck, expecting the baby pandas to appear.

　　　　"Mei Xin, Guaibao, go home!" The breeder called "Meixin" who was playing outside the stadium in Sichuan dialect, and put the cage at the door of the animal house. Soon, "Meixin" got into the animal house, but "Fuwa" followed. The two little guys were attracted by carrots in the cage and blocked the cage door.

　　　　Li Feng, the breeder, waved a pot of carrots in front of Fuwa. Fuwa was attracted, only to find that the food outside the animal house could not be eaten, and immediately went to squeeze the door with Meixin. Seeing that there were more carrots in Li Feng’s hand than in the cage, the greedy cat "Meixin" stared intently at the food basin and followed the breeder to climb to the next animal house. The breeder patted Meixin’s nose, talked to her constantly, fed her, and calmed her mood. In about 5 minutes, "Meixin" was the first to be successfully "lured" into the cage.

　　　　At 11: 30 in the morning, the last baby panda was caged with fresh bamboo, apples and carrots.

　　Recently, the regulation of the property market in hot cities has been tightened, and real estate financing has also been strongly regulated. A number of bankers said that in the second half of the year, they will strictly and prudently manage loans in the real estate sector and control development loans and mortgage loans in accordance with the requirements of the regulatory authorities. In the future, there is little room for further improvement in the proportion of real estate in financial resources. At the same time, the credit policy will be adjusted and optimized around the regulatory requirements, and the support for the real economy will be increased.

　　Some areas raised mortgage interest rates.

　　According to the monitoring data of Rong 360 Big Data Research Institute, from the end of July to the beginning of August, the mortgage interest rates in Suzhou, Hangzhou, Dalian and Ningbo all increased.

　　Li Wanbin, an analyst at Rong 360 Big Data Research Institute, said that the increase in mortgage interest rates was due to overheating of the property market in some cities, and local governments adjusted by raising mortgage interest rates. In addition, the bank’s credit funds in the second half of the year are often not as abundant as those in the first half of the year, and the mortgage amount is also relatively tight. Under this circumstance, the bank will also choose to raise the mortgage interest rate.

　　"It is expected that more regions will raise the mortgage interest rate, and the amount will be relatively tight, but it does not rule out that some banks in some regions will lower the mortgage interest rate from the bank’s own funds and business strategies." Li Wanbin said.

　　According to the statistics of the Central Plains Real Estate Research Center, at present, the mortgage interest rates in various places are basically stable, with few obvious fluctuations, and most banks are still lending normally. Judging from the major first-and second-tier cities in China, the current interest rate level fluctuates slightly compared with the second quarter, but most cities still maintain the lowest interest rate in the past two years.

　　Wang Yifeng, chief analyst of Everbright Securities Banking, said that housing mortgage loans have grown rapidly since this year. Under the background of stable housing prices, stable expectations and city-specific policies, real estate policies in various cities have maintained pressure, and mortgage interest rates have diverged to some extent. Judging from the current situation, the demand for housing mortgage loans is relatively stable.

　　Real estate credit policy will be tightened.

　　Recently, the central bank named real estate finance twice, emphasizing maintaining the continuity and stability of real estate financial policies and continuously strengthening the control of funds in the real estate market. A number of insiders told china securities journal that loans in the real estate sector will be managed strictly and prudently in the second half of the year according to the requirements of the regulatory authorities.

　　The president of Suzhou Branch of a big bank said that in the first half of the year, the bank’s investment in real estate accounted for less than 30% of the total investment, and development loans and mortgage loans will be more strictly controlled in the second half of the year.

　　According to the vice president of Wuhan Branch of a joint-stock bank, the real estate credit of the bank did not exceed 40% in the first half of the year. "Every year, our bank’s asset structure layout of the industry is orderly. In the second half of the year, the whole bank will implement total amount control and preferential selection to support rigid demand. In general, banks’ control over real estate credit will become more and more strict. "

　　"Our real estate loans are very few, and now under the requirements of policy regulation, we will not take the initiative to market." The president of a stock bank in Changzhou, Jiangsu Province said that the mortgage interest rates of the first and second suites of the bank are 10% and 15% higher than the benchmark interest rate respectively, and the mortgage interest rates will be adjusted according to market conditions in due course.

　　"From a policy perspective, it is expected that the proportion of real estate in financial resources will be carefully regulated in the future, and there is little room for further improvement in the proportion of real estate in financial resources." Lian Ping, chief economist of Bank of Communications, believes that at present, under the requirement of "housing and not speculating", most first-and second-tier cities have strict control over the property market, and it is impossible to speculate on real estate on a large scale. In the future, real estate credit should do its homework from the structure and match the reasonable demand in line with reality.

　　For example, Lian Ping said that from the perspective of mortgage, under the current strict control policies, the market demand in many places is still rigid and benign, and banks should support it. In terms of development loans, banks and non-bank channels should also give support if there is benign and reasonable demand in the market.

　　The credit direction will be adjusted in the second half of the year.

　　A number of banking industry insiders said that the credit policy will be adjusted around the regulatory requirements in the second half of the year. The vice president of Wuhan Branch of the above-mentioned joint-stock bank said that the bank invested heavily in private enterprises and inclusive finance in the first half of the year, and will increase credit support for manufacturing industry in the second half of the year according to regulatory requirements.

　　Wang Yifeng said that significant growth in manufacturing and medium and long-term loans required further policy arrangements. With the gradual consumption of pre-reserve projects, loans to the public have been weak. In the future, how to promote the rapid growth of manufacturing loans needs further policy guidance. In addition, how to effectively activate the vitality of micro-subjects, especially the effective demand of funds, also needs more effective policy support.

　　It is worth noting that the regulatory authorities have made arrangements to increase support for the manufacturing industry. Yang Liping, chief prosecutor of China Banking and Insurance Regulatory Commission, said earlier that China Banking and Insurance Regulatory Commission asked banks to set annual service targets for manufacturing industry, mainly to tackle key core technologies in the field of sticking neck, and to support key areas such as strategic emerging industries and transformation and upgrading of manufacturing industry, so as to realize that the balance of manufacturing loans was significantly higher than that of last year. At the same time, improve the professional ability of service manufacturing industry, supervise large banks to optimize the term of loans, match the production and research cycle of manufacturing enterprises, and increase the medium and long-term loans. Those who can make credit loans will insist on reviewing the first repayment source and make credit loans.

CCTV News:The Beijing West Railway Station is still brightly lit in the middle of the night, and passengers are carrying big bags and small bags to their respective destinations in the crowded crowd. For Wang Linna, the captain of "036" who serves key passengers, her night shift has just begun.　

"Looking for’ 036′ in difficulty" is a warm word circulating in the waiting room of Beijing West Railway Station, and it is also a solemn promise of several generations of "036" passengers. Over the past fifteen years, the inheritors of "036" have been devoted to their posts, provided practical services, and practiced the service tenet of "treating passengers like relatives" with actions. As a new generation of successors, Wang Linna led the energetic "036" team and won the praise of thousands of passengers with sincere service.

"036" Team of Passenger Transport Class C　

From one person to a group.

"036" was originally the name tag number of Li Shuzhen, a passenger attendant at Beijing North Railway Station in 1970s. She was sincere and enthusiastic, and was praised by many passengers. In 1998, the second generation of "036" passenger attendants and Beijing model workers — — Song Minjuan transferred from Beijing North Railway Station to Beijing West Railway Station, bringing the excellent practice of "036" service, and the spirit of "036" began to take root in Beijing West Railway Station. In 1999, Beijing West Railway Station officially named the special waiting room for the elderly, young, sick, disabled and pregnant key passengers as "036". The fourth generation of "036" passengers, represented by Wang Fenglian, inherited and carried forward the spirit of "036" and "one heart, full of enthusiasm, to solve problems for passengers" of the older generation such as Li Shuzhen, Song Minjuan and Hu Zongying. Nowadays, Wang Linna, the successor of the fifth generation "036", is affectionately called "the most beautiful smile in the waiting room" by the passengers for his patient, meticulous and enthusiastic service.

Wang Linna serves key passengers.

Liu Yongxin is one of the many phone numbers of travelers who come and go to see a doctor in Wang Linna’s mobile phone.

In the summer of August, 2012, Wang Linna found Liu Yongxin who had just finished leg surgery. He was a national basketball player. Because of leg surgery, he missed the 2012 exam and failed to realize his dream of going to Beijing Sport University. At that time, Liu Yongxin was very depressed and lacked confidence in his future life, so Wang Linna comforted him to take good care of his illness and enlightened him to be optimistic. Before parting, Wang Linna also specially exchanged telephone numbers with Liu Yongxin. In the following three months, Wang Linna kept in touch with him and encouraged him to cheer up and face the future bravely like a big sister. On the phone, Wang Linna also promised that no matter how busy he was when he came to Beijing for reexamination, he would personally escort him on and off the bus.

In mid-October, Wang Linna was not on duty when he got a call from Liu Yongxin to Beijing again, and his two-year-old daughter was ill and hospitalized. There is no time to take care of the children at ordinary times, and I can’t accompany them when I am sick. Wang Linna, a mother, is very guilty. But when thinking of the passengers in need and his original promise, Wang Linna resolutely returned to the station.

A passenger wrote in her thank-you letter: "For my mother, who is seriously ill, your warm help is like a ray of sunshine, giving her infinite warmth." In this way, Wang Linna and her "036" team inherited and carried forward the traditional virtues of "036", moved forward together, solved difficulties with considerate service, warmed passengers with sincere care, and became smiling angels in everyone’s eyes.

The travelers became friends with them.

"036" passenger escort key passengers to the platform.

As the railway passenger station with the largest number of passengers in China, during the holiday transportation, the passenger attendants in the "036" waiting room often have to work continuously for 15 or 6 hours, but everyone never complains or shouts tired, and only leaves a bright copy to the passengers.

"036" passenger guides key passengers

On October 2, 2013, the waiting room of the Golden Week was overcrowded. From 8: 00 a.m. to take over, in less than half an hour, Wang Linna has already picked up three passengers in wheelchairs. "Can you take us to the train gate?" When Sheng Litang from Lianyungang made this request, he was slightly embarrassed and uneasy. His wife suffers from femoral head necrosis, and it is very inconvenient to go home by train after seeing the disease in Beijing. Wang Linna immediately found a wheelchair to help take the patient to the waiting room, and then comforted the husband and wife: "Please wait here first, and we will send you directly to the car, don’t worry."

As soon as the Shenglitang couple were arranged, Wang Linna welcomed five more tourists to Urumqi, including an 80-year-old grandmother and a 10-year-old child in a wheelchair. Wang Linna’s footsteps haven’t stood firm, and then he pushed the old man and led the family to set off. Only when I got to the platform did I know that the five passengers were not in the same carriage. Wang Linna patiently settled them in turn before leaving.

Thinking of Mr. and Mrs. Sheng in the waiting room, Wang Linna hurried to see the car off after a busy wheelchair trip. Knowing that they would come to Beijing for treatment, Wang Linna handed in a love contact card, reminding that every waiter would serve wholeheartedly when he came directly to the "036" waiting room at the West Railway Station next time.

Wang Linna Record Key Passenger Service Card

Willing to endure hardship and dedication is the consistent style of "036", and realizing the value of life in dedication is regarded as the standard by them. For them, tourists have become friends, even relatives. They have taken pains, regardless of fame and fortune, as long as they can harvest a smile and a greeting, it is enough.

Based on the needs of passengers, seeking development through innovation

"036" Innovative Invention of Electric Wheelchair

Today, Wang Linna and her team are not satisfied with the original service means and measures. On the basis of inheriting and carrying forward the spirit of "036 Four Hearts", they have created the "One-stop Service Law" and "Five A Work Law" in close combination with reality, which has made the spirit of "036" show new charm and made new development. At the same time, the "036" team made full use of the station and the official Weibo of "036" on the basis of on-site reservation and telephone reservation, and opened the online reservation service, which further facilitated the travel of key passengers.

On January 10th, 2013, a netizen named "Passing a colorful grandson in a dream" sent a message for help through Weibo. His name is Sun Long, a student who goes to college in Lanzhou and lives in Shenyang. Before the holiday, Sun Long’s right leg was accidentally broken, so it became a big problem to go home by train for the New Year. After receiving information from the official Weibo of Beijing West Railway Station, the "036" waiting room arranged the pick-up work in advance according to the specific boarding date and train number provided by Sun Long.

On January 13th, Sun Long took the Z56 train from Lanzhou and entered the platform. With the help of the conductor, Wang Linna successfully reached Sun Long in a wheelchair. Because Sun Long’s leg injury can’t be hit and shaken again, Wang Linna tried to keep his feet steady all the way to make him more comfortable in a wheelchair. After leaving the station, Wang Linna quickly contacted Beijing Railway Station and Shenyang Railway Station to help them arrange the transfer of Sun Long’s family. During the Spring Festival, Wang Linna received a short message from Sun Long, with deep affection between the lines, expressing his gratitude to all the staff who helped him. On February 20th, Weibo, the official of Beijing West Railway Station, received a message from Sun Long again. He will take the T75 train on the 24th and return to Lanzhou. On the same day, Wang Linna also received a short message from Sun Long, hoping to get him on the bus by Wang Linna. When I saw Sun Long again, his leg injury improved obviously, but he still needed a wheelchair to pick him up. At 3: 15 pm, Wang Linna received Sun Long at the entrance on the second floor and sent him to the door of the carriage smoothly. After arranging the berth, Sun Long said to Wang Linna, "Sister Wang, thank you. You passed on your warmth and love to me, and I will pass it on again!"

This simple sentence made Wang Linna very pleased.

Fifteen years is only a blink of an eye in the long river of history, but it is a growth history for the "036" team to stick to their posts and March forward courageously towards high standards and strict requirements. As time goes by, "036" has become synonymous with advanced title, and it is also a shining railway quality brand.

The renovation of old residential areas is a major livelihood project and development project. General Secretary of the Supreme Leader pointed out that the renovation of old residential areas is an important task to enhance people’s sense of gain, and it is also an important part of the implementation of urban renewal. The Community Construction Department of the Urban Construction Department of the Ministry of Housing and Urban-Rural Development (hereinafter referred to as the "Community Department") takes the transformation of old residential areas as the focus of doing practical things for the masses, and solves the "great livelihood" with "small incision" to continuously enhance the people’s sense of acquisition, happiness and security.

This year, this young team won the National Worker Pioneer. "The renovation of old residential areas is an important task to improve people’s quality of life, and it is a practical matter of people’s livelihood around the people. We are honored to be able to shoulder the heavy responsibility and win the honor, and we feel even more responsible. " Relevant comrades in the community office said.

Find out the base, pilot first, and clarify the direction of the transformation path

Most of the old residential areas were built before 2000. The construction standards of these residential areas are low, coupled with long-term neglect, incomplete municipal supporting facilities, aging houses and other outstanding problems. There are shortcomings in facilities, environmental supporting facilities and public services, which is far from the growing needs of the people for a better life. Residents have a strong willingness to transform. Old residential areas are large in quantity and wide in scope, and the task of renovation is heavy. How to promote renovation in a solid and orderly manner throughout the country?

Understanding what the masses think and expect, and learning from the grassroots is the first priority. The Community Department organized 20 departments and units to conduct in-depth research on 213 old communities in 93 cities and counties, and combed and analyzed the current situation, transformation needs and experience of old communities. Subsequently, Shandong and Zhejiang provinces and eight cities including Shanghai and Suzhou were organized to deepen the pilot projects, and special classes for joint work were set up with local comrades to jointly explore the establishment of nine mechanisms, such as mobilizing the masses to jointly build, sharing reconstruction funds and integrating and utilizing existing resources, and to "explore the road" in the reconstruction projects in detail, so as to accumulate experience for comprehensively promoting the transformation.

On the basis of comprehensive investigation and summing up the pilot experience, the Community Department took the lead in drafting the Guiding Opinions on Comprehensively Promoting the Renovation of Old Urban Residential Areas, which defined the target tasks and the scope of objects, established a package of support policies to meet the needs of renovation projects in terms of approval of renovation projects, taxation and finance, land and so on, basically formed the institutional framework for the renovation of old urban residential areas, and the renovation work was rapidly and comprehensively promoted throughout the country.

Guide the whole process and do a good job in deployment and implementation.

Since 2019, the country has started to renovate nearly 220,000 old urban communities, benefiting hundreds of millions of people. However, the larger new start-up tasks every year, coupled with the projects under construction, have brought great pressure to the streets and communities at the grassroots level. How to make the policy better adapt to the needs of the grassroots and land solidly?

The community department insists on keeping its eyes down, stepping down, throwing itself down and sinking into the front line, so that the policy can be passed on layer by layer from formulation to promotion to landing.

"The transformation of old residential areas is the initial intention and mission of this office. We are both policy makers and policy practitioners and implementers." Relevant comrades said.

According to reports, since 2019, the renovation of old residential areas has been included in the affordable housing project, and the General Office of the State Council has issued guidance. The Ministry of Housing and Urban-Rural Development, together with relevant departments, put forward targeted work requirements for the renovation work in that year according to the latest situation, tasks and objectives, and new situations and problems arising in the renovation, and made clear the "positive list" and "negative list" of work, so as to promote all localities to do their best and do their best to promote the renovation well and quickly.

With the gradual advancement of the renovation of old residential areas, the Community Department promptly answered questions about the difficulties encountered in various localities, followed up and summarized the deepening innovations in the implementation of policies in various localities, organized and printed seven batches of List of Replicable Policy Mechanisms for the Renovation of Old Urban Residential Areas, promoted the replicable experiences and practices in pioneering areas, guided all localities to learn from them, accelerated the improvement of working mechanisms and policy systems that meet the needs of renovation, and promoted the implementation of renovation policies.

For example, in order to solve the problem of "public needs and women need to face" in the transformation of old residential areas, the community department guides all localities to fully mobilize the masses to participate, ask for the needs of the people, ask for the people, ask for the benefits of the people, and seek the greatest common denominator of the transformation effect.

In the residents’ meeting hall of an old residential area in Qingdao, Shandong Province, a young cadre from the community office discussed the renovation plan of the residential area with the residents. Because there are many people in the surrounding primary schools during school hours, the residents are very concerned about the design plan of optimizing the internal traffic routes and getting through the fire exits. "Making policies and implementing them are different. Every old residential area has its own characteristics, and the needs of each resident are different. The renovation plan must be determined according to the wishes of residents and the actual situation of the residential area. In this process, it is very important to be with residents, want to be together, and be together. " The young cadre said with emotion.

Experience comes from grassroots practice and wisdom. The community department adheres to the typical demonstration and leads the way, and promotes the transformation process in various places with demonstration projects. Since 2021, the Community Department has identified a number of contact points communities every year, and adopted the methods of leaders’ efforts, young cadres’ on-the-spot investigation, and experts’ assistance to help the communities break the blocking points of renovation, create demonstration model projects, and share experiences and experiences with community cadres in the streets where various renovation communities are located throughout the country.

In order to evaluate the transformation work more scientifically and objectively, the community office has defined the measurement standard of the transformation work through performance evaluation, supervision and encouragement, so as to make the policy baton and the evaluation index system more unified. During the research and establishment of the National Statistical Investigation System for the Renovation of Old Urban Residential Areas, the Community Department, together with grassroots comrades, repeatedly studied the connotation of each statistical indicator in order to be accurate and efficient, focusing on the goal of timely and accurately reflecting the progress of the renovation and minimizing the statistical burden. "This set of statistical indicators has clear logic and strong pertinence, which is very helpful for guiding and promoting local work. The progress of the work can be clearly reflected in the statistics. Behind the figures are the transformation results that every resident can see and touch, and they are all tangible results. " A grassroots cadre responsible for the renovation of old communities said.

The central and local governments have resonated at the same frequency and exerted their strength in the same direction, overcoming difficulties and taking advantage of the situation. The policy implementation has not only not weakened, but the signal has become stronger and stronger.

Cooperate to fill the shortcomings and improve the supporting facilities

Living and working in peace and contentment is the simplest wish of China people. Residents spend most of their daily life, food, clothing, housing and transportation in the community. In order to do the "last mile" of serving the masses well, the Community Department cooperated with various departments Qi Xin to integrate resources and fill the shortcomings of facilities and services.

"what is missing, what to make up." The Community Office guides all localities to explore the working method of "physical examination before renovation", and before renovation, it conducts a thorough investigation of the facilities in the community, focuses on residents’ needs, adheres to goal orientation and problem orientation, adopts "menu-based" renovation, and makes precise efforts with "one district, one policy", giving priority to solving the urgent problems of the masses, using limited funds at the cutting edge and changing them into residents’ "hearts".

"Stick to the bottom line of safety" and focus on eliminating potential safety hazards. Accelerate the renovation of aging and hidden dangers of gas, water supply, heating, drainage, power supply, communications and other pipelines and pipelines, and put the concept of safe development throughout all links and the whole process of renovation.

"One old and one young" is the main concern of most families. The Community Department guides all localities to actively revitalize the housing and land resources in the community and surrounding areas, and add service facilities such as home care service centers, canteens for the elderly and children’s post stations according to local conditions. In conjunction with the State Sports General Administration, the "national ball into the community" campaign was launched, and small sports and fitness facilities such as table tennis tables were added for old communities to allow residents to move at their doorsteps.

In recent years, residents have a high voice for installing elevators in existing houses, and the community department has faced up to the difficulties of reaching a consensus and raising funds, and adhered to the combination of rule of law and rule of virtue to help solve the problem of "it is difficult for suspended elderly people to go downstairs". Seize the favorable opportunity when the National People’s Congress promulgated the law on barrier-free environment construction, and promote national legislation to support the installation of elevators in existing multi-storey houses in old urban communities. Give play to the role of grassroots organizations in street communities, take party building as the guide and residents’ consultation as the basic working methods, and promote residents to reach a consensus. In conjunction with the Supreme People’s Court, a typical case was issued to guide residents to correctly understand the legal provisions applicable to installing elevators, and to carry forward the traditional virtues of the Chinese nation, such as being good neighbors and helping each other.

Great cause inspires people to forge ahead. The achievements made by the Community Office courageously come from the broad masses of the people’s support for the major decision-making arrangements of the CPC Central Committee and the State Council, and also reflect the hope of millions of grassroots community workers and community residents to work together to build a beautiful home.

Percutaneous argon-helium knife treatment of liver cancer is one of the non-surgical treatment methods in recent years, which indicates that the treatment of liver cancer has entered a new stage of cryotherapy. Professor Yang Yongping, director of the Department of Hepatology and Medicine, Fifth Medical Center, General Hospital of Chinese People’s Liberation Army, shared the cryoablation treatment of liver cancer in the first multi-disciplinary cooperation forum of Anhui Province, and the platform of treating liver cancer with sincerity specially compiled the essence for readers.

Overview of liver cancer

In China, hepatocellular carcinoma (HCC) is the fifth largest malignant tumor and the second largest tumor-related death cause, with a five-year survival rate of only 14.2%. How to treat liver cancer scientifically and benefit the long-term survival of patients is an important clinical problem, and it is also the gold standard to measure the treatment level of medical units. In 2022, the updated guidelines for prognosis and treatment strategy of clinical liver cancer (BCLC) in Barcelona proposed that patients with HCC should be accurately evaluated individually. Doctors need to fully consider the scope and load of the tumor, the nutritional status and human performance of the patient, complications, age, etc., and formulate individualized treatment methods for the patient.

No matter what stage the patient is in, local ablation is an important treatment. At present, a variety of mature local ablation treatment techniques for liver cancer have been formed, including radiofrequency ablation, microwave ablation, cryoablation, irreversible electroporation (nano-knife) and so on.

Overview of cryoablation therapy

Cryoablation therapy has experienced a long development process. In 1800, James Arnott discovered that the mixture of ice and salt could delay the progress of breast cancer, uterine cancer and skin cancer. In 1950, liquid nitrogen and dry ice were used to treat different kinds of diseases, especially benign skin lesions. In 1961, Cooper and Le introduced the first automatic cryosurgical equipment, but it used liquid nitrogen as refrigerant, which had many complications and was only used in laparotomy. In the 1970s and 1980s, liquid nitrogen needle was used to treat prostate hypertrophy and prostate cancer, but the cryoablation technology was stagnant due to many complications. In the 1990s, intraoperative ultrasound monitoring of freezing process was used in surgery by scholars, and argon was studied as the refrigerant. In 1998, the third generation cryosurgery system (Argon-Helium cryosurgery system) came out in the United States, which used argon as the refrigerant and helium as the heat medium, bringing revolutionary progress to minimally invasive cryosurgery. In 2000, cryotherapy entered American medical insurance. In 2003, the World Congress of Targeted Cancer Therapy recommended cryoablation as the first choice for advanced lung cancer and liver cancer. In 2010, the standardized diagnosis and treatment of liver cancer promoted by the Health Planning Commission listed cryoablation as a local treatment for liver cancer. In 2016, after more than 10 years of unremitting efforts, Professor Yang Yongping’s team led the overall and comprehensive innovation and development of percutaneous cryoablation of liver cancer at home and abroad, changed the international prejudice on cryoablation of liver cancer, turned the small path into the big road, the irregular into the norm, and the unpopular into the hot spot.The technological innovation of cryoablation of liver cancer won the first prize of Beijing Science and Technology Progress Award. In 2018, 2019 and 2020, experts’ consensus on imaging-guided cryoablation for lung cancer, experts’ consensus on imaging-guided cryoablation for bone and soft tissue tumors, experts’ consensus on imaging-guided cryoablation for kidney cancer and experts’ consensus on imaging-guided cryoablation for liver cancer were released respectively. So far, NCCN, AASLD, APASL, EASL and other guidelines have recommended cryoablation for the treatment of primary liver cancer.

At present, the Department of Hepatology Medicine of the General Hospital of the Chinese People’s Liberation Army has become the largest medical center for treating liver tumors in the world last year, constantly exploring the innovation of cryoablation technology, adopting high-vacuum heat insulation technology, only destroying the tumor site without damaging the surgical path, and adopting multi-stage heat exchange technology, which makes the refrigerant utilization rate higher and the cooling rate faster, and it is easier to induce the frozen immune response of liver cancer patients, activate their own anti-tumor immunity and produce ectopic tumor inhibition.

Therapeutic mechanism and characteristics of cryoablation technology

The cryoablation area is composed of central coagulative necrosis area and peripheral tissue injury area with different degrees. The mechanism of rapid direct cell necrosis in the central area includes mechanical damage caused by ice crystal formation inside and outside the cell and osmotic damage caused by dehydration and rupture of the cell. Peripheral injury areas are mainly related to freezing-related secondary injuries, including hypoxia death of tumor tissue caused by blood embolism, apoptosis caused by reversible injury, and waterfall-like ectopic tumor suppression by stimulating immune regulation.

The characteristics of cryoablation technology include: ① clear treatment boundary, real-time monitoring under image, safe and reliable treatment; ② Treatment can stimulate human immunity and strengthen tumor treatment; ③ Physical therapy is non-toxic to human body, with extremely low side effects; ④ The treatment is painless, without general anesthesia and participation of anesthesiologists, and the treatment is convenient; ⑤ Not limited by the artificial pacemaker installed in the body; ⑥ Effective, suitable for lung cancer, liver cancer, kidney cancer, breast cancer, prostate cancer and other solid tumors.

In addition, ultrasound, CT, laparoscopy or intraoperative direct vision guidance can be used for cryoablation treatment, and the tumor position and the formation of ice hockey can be monitored in real time.

Current situation of percutaneous cryoablation of HCC

Before 2005, based on the previously reported clinical research results, there were many complications, such as bleeding, liver parenchyma frost crack, freezing shock, coagulation dysfunction and so on. International scholars were cautious about this technology. After 2005, percutaneous cryoablation for liver cancer has developed in China, especially with the publication of China’s continuous clinical summary and high-level evidence in the top international journal Hepatology. More and more clinical studies have confirmed that percutaneous cryoablation for liver cancer is safe and effective, and international scholars have a positive attitude.

Professor Yang Yongping’s team took the lead in conducting clinical research to determine the indications of liver cirrhosis-related HCC by percutaneous cryoablation. In this study, 1681 patients with liver cirrhosis-related HCC and 682 patients with advanced HCC were selected, and the indications and standards of complete cryoablation and selective cryoablation were established. It was proposed that the ablation volume of the target lesion should exceed 50% of the tumor volume or minimize the tumor load, relieve the symptoms caused by the tumor, improve the quality of life and prolong the survival time. The study also innovatively changed the percutaneous puncture to guide needle to locate the introduction of vascular sheath to solve the problem of bleeding after cryoablation, which has been cited by foreign counterparts for many times and suggested routine application.

Indications for complete cryoablation of liver cancer:

① The maximum diameter of a single tumor is less than 5 cm, or the number of tumors is less than 3, and the maximum diameter is less than 3 cm;

② Recurrence after surgical resection or other local treatment meets the conditions ①;

③ Child-Pugh A or B of liver function, bilirubin level ≤51.3μmol/L, or reaching this standard after medical treatment;

④ The blood coagulation function is good (prothrombin activity > 40%, platelet count > 30×109//L, using sheath hemostasis and packing system);

⑤ECOG PS ≤2；

⑥ Cirrhosis, including a history of chronic liver disease, with enlarged hepatic fissure/metacentric colon/esophageal varices/gastric varices/serrated liver surface, a history of upper gastrointestinal bleeding or ascites, and platelets < 100×109/L..

Indications for selective cryoablation of liver cancer:

① Single tumor with a maximum diameter of > 5cm or multiple tumors with a maximum diameter of > 3cm that cannot be surgically removed, regardless of whether there is tumor thrombus in portal vein;

② Child-Pugh A or B liver function classification, bilirubin level ≤51.3μmol/L or reaching the standard after medical treatment;

③ The blood coagulation function is good (prothrombin activity > 40%, platelet count > 30×109/L, using sheath hemostasis and packing system);

④QECOG PS ≤2；

⑤ Cirrhosis, including a history of chronic liver disease, with widened hepatic fissure/metacentric colon/esophageal varices/gastric varices/serrated liver surface, a history of upper gastrointestinal bleeding or ascites, and platelets < 100×109/L..

In addition, Professor Yang Yongping’s team innovatively established measures to prevent and treat complications of percutaneous cryoablation of hepatocellular carcinoma. In this study, 3321 patients were selected, and the measures of percutaneous cryoablation of liver cancer complications were established and verified (Table 1).

Table 1 Measures for Complications of Percutaneous Cryoablation of Liver Cancer

Moreover, the study has achieved encouraging clinical results, which increased the complete tumor ablation rate by 10.6%, reduced the local tumor recurrence rate by 30.3% in 5 years, and improved the 5-year survival rate by 16.6%.

Advantages of cryoablation in the treatment of hepatocellular carcinoma

Although cryoablation has distinct advantages over radiofrequency ablation (RFA), there is no RCT study in the past to directly compare the efficacy of ablation of liver cancer, especially the safety. Professor Yang Yongping’s team designed RCT study in five years to evaluate the efficacy and safety of percutaneous cryoablation and radiofrequency ablation of liver cancer. For the tumor, there were statistical differences in the local tumor progression rate between the two groups at 1, 2 and 3 years: 3%, 7% and 7% in the frozen group, respectively; The RF group was 9%, 11% and 11% respectively (P = 0.043). Subgroup analysis: For hepatocellular carcinoma with a diameter of > 3cm, cryoablation has a lower local tumor progression rate (cryoablation vs. RF: 7.7% vs. 18.2%, P=0.041). There was no statistical difference in the local tumor progression rate between 1-2cm (frozen vs. RF: 0% vs.2.4%, P=1.000) and 2.1-3.0cm (frozen vs. RF: 4.1%vs.7.1%, P=0.656). The results were published in Hepatology magazine and also in China.

Professor Yang Yongping’s team also confirmed that cryoablation of HCC can produce ectopic tumor inhibition, with the incidence of ectopic tumor inhibition of 6.3%, and the median survival time of patients with ectopic tumor inhibition was significantly prolonged. The mechanism is related to the down-regulation of PD-1/PD-L1 and regulatory T cells after ablation. In addition, argon-helium cryotherapy is effective for elderly HCC.

Unresolved problems in cryoablation of HCC

There are also many problems to be solved in the process of cryoablation for HCC in the future:

1. Does tumor cell ablation release specific tumor cell death signal?

2. How can freezing produce the best ratio of necrosis and apoptosis?

3. Are the cytokines released after freezing derived from tumor microenvironment or natural immune response, and what is their time sequence?

4. Will the functional essence and time sequence of antigen presenting cells that absorb necrotic tissue change after cryoablation?

5. What is the effect of cryoablation and absorption of necrotic tissue on the immunosuppressive function of the body? How to reduce the immunosuppression of the body?
