The movie ＂Hidden Married Men and Women＂ started. Rene Liu did not deny that he would get married secretly.

　　　 Movie network news(Photo/Qian Jiayi/Theway) A film "Hidden Marriage Men and Women" reflecting the phenomenon of hidden marriage in the entertainment circle was held in Beijing on October 19th, with director Ye Nianchen and starring Rene Liu, Eason Chan, Yu Chengqing and Bai Bing all appearing. Several leading actors all work for perfume companies in the film. At the press conference, Rene Liu and Bai Bing also specially painted different kinds of perfumes to let Eason Chan and Yu Chengqing distinguish by their sense of smell with their eyes closed. Asked about his personal views on hidden marriage, Rene Liu, who is still single, bluntly said: "Marriage is a matter for two people, and others should not give advice."

Rene Liu admits that it does not exclude hidden marriage from being "Scent of a Woman" in Eason Chan.

　　　 In The Hidden Marriage, Rene Liu, a milk tea, changed her intellectual image and played a devil in the workplace, while Eason Chan played her assistant, a man who chose to be hidden for his wife (Bai Bing) to have a better life, and Yu Chengqing played a playboy. Rene Liu introduced: "In fact, this role is looking for a man who has never been married as an assistant in the hope that he can (develop) with himself, and it depends on watching movies." And she herself does not reject the practice of hidden marriage. "Marriage is a matter for two people. Whether to get married or not is a matter for others, and others should not be around."

　　　 In order to fit in with the fact that several leading actors in the film all work in perfume companies, the conference specially set up a "Scent of a Woman" link. Rene Liu and Bai Bing painted different perfumes on their wrists respectively, while Eason Chan and Yu Chengqing closed their eyes and only relied on their sense of smell to identify who they smelled. Compared with Yu Chengqing, they successfully guessed that Bai Bing put his arm in front of them, but Eason Chan failed to guess the perfume painted by Rene Liu, and thought it was white ice, which was a bit embarrassing.

The meteorological department issued the ＂Six Early Warning＂ for three consecutive days to remind people to make reasonable arrangements for travel and add clothes to keep warm.

CCTV News:In the past two days, a wide range of rain, snow and freezing weather has continued in the central and eastern regions of China. On February 21st, the Central Meteorological Observatory issued six warnings for the third consecutive day. On February 21st, the Central Meteorological Observatory issued an orange warning for cold wave, a yellow warning for snowstorm, freezing and fog, and a blue warning for strong wind and strong convective weather.

The Central Meteorological Observatory predicts that on February 21, the precipitation in the central and eastern regions will remain strong, and the boundary between rain and snow will be pressed to the south, and the northern Jiangsu and Anhui provinces and northern Hubei will now be blizzards.

Micro-nano Robot： Exploring the Mysterious Micro-world

　　Author: Huang Tianyun (researcher, Department of Advanced Manufacturing and Robotics, State Key Laboratory of Micro-nano Machining Technology, State Key Laboratory of Turbulence and Complex Systems, Peking University Institute of Technology)

　　For human beings, there are still many puzzles in the micro world — — Little is known about water bear worm, the most tenacious micro-organism on the earth, micron-scale Escherichia coli known as "microbial factory", even nano-scale phage that can parasitize in Escherichia coli, and DNA encoded by molecular genes containing mysterious origin of life. For nearly half a century, people have been eager to create a micro-robot that can enter the micro-world, put on the "soft hedgehog armor" of water bears, sneak into the "brain" of E.coli, listen to the "whisper" of bacteriophages, direct gene synthesis of protein, cooperate with cells to complete the evolution of life, and "see" what happened in the micro-world instead of human beings. Maybe in the near future, this wish will come true — — Micro-nano robot.

　　The microscopic world with a unique hole in the sky

　　Micro-world is a magical and unknown "land of bliss", and there are many incredible magical scenes. With the decrease of size, the micro-scale spatio-temporal effect gradually appears. Here, the surface area of an object increases in inverse proportion to the volume ratio, which means that in the micro-scale world, the energy dissipation is more intense, the metabolism of living beings is accelerated, and the life cycle is shortened; The low Reynolds number characteristics of microfluidic environment show that viscous force is dominant, inertial force can be ignored, and the object seems to be placed in very viscous honey. At the nanometer scale, objects will be subjected to more intense intermolecular interactions, such as van der Waals force. At this time, the action of gravity on the object can be approximately ignored, at the same time, the mechanical collision of molecules is more obvious, and the irregular Brownian motion is relatively more intense.

　　In this seemingly extremely harsh micro-world, there are many kinds of tiny agents, which show tenacious vitality and strange functions. For example, the water bear worm is a kind of submillimeter-long micro invertebrate. With its unique physiological structure and powerful gene repair ability, it can show its unique hidden "stunts" when the environment deteriorates, so as to withstand extreme environments such as extreme heat and drought, extreme cold and freezing near absolute zero, high altitude hypoxia, deep-sea high pressure and high-dose radiation in outer space. In the microbial world, which is difficult to distinguish with naked eyes, there are still a surprising number of micron-sized single-celled organisms, such as original vivid plants, bacteria, fungi, mycoplasma, chlamydia and so on. They are widely distributed in nature and are closely related to human production, life and survival. In addition, viruses composed only of nucleic acid molecules and protein’s protective shell, because they do not have complete cell morphology and are separated from the host, can not independently complete metabolism, and are usually considered as nonliving. However, they have the ability to selectively absorb the host and complete self-replication and proliferation with the help of the raw materials provided by the host cells after invasion, showing amazing swarm intelligence and behavior.

　　Moreover, the operation of the micro-world is highly organized. As we all know, cell is the basic unit of organism, and its interior is more like a complex and busy but well-organized "micro-machine factory". The nucleus is the control center of the factory, where the DNA encoded by information is copied and transcribed into mRNA under the catalysis of enzymes. After splicing and modification, the mRNA enters the cytoplasm and is in the synthesis workshop in protein — — Translation is carried out in ribosomes, and many individual amino acids are assembled into protein long chains. These protein are packaged and decorated, and the protein driven by "freight locomotive" is transported to the designated area with microtubules as guide rails. The locomotive power is provided by the molecular fuel cell ATP produced by oxidative metabolism of mitochondria in the "power station" in the factory. How to make the whole operation process of this micro-machine factory so accurate, controllable and efficient has always been the ultimate mystery of life that scientists hope to solve. It is of great significance to reveal the mystery of micro-life, improve the efficiency of biosynthesis and improve the direction or path of biological metabolism, and can provide important technical support and material guarantee for the sustainable development of mankind in the future.

　　Micro-nano robots born for exploring the micro-world.

　　Nature is ingenious, and it can build such exquisite intelligent life bodies as DNA, ribosome, phage, Escherichia coli and so on on the micro-nano scale. In engineering, scientists are also trying to imitate the way of nature, create similar artificial agents at the micro-scale, use them to enter the micro-scale, participate in regulating the growth and evolution of life in different dimensions and stages, and finally realize self-organization and emerge controllable systematic macro-behavior through the interaction between these artificial micro-machines and organic life.

　　Here, let’s roughly define "micro-nano-robots": they are intelligent micro-mechanical systems, usually ranging in size from submillimeter to tens of nanometers, and are considered to be used to adaptively and autonomously complete controllable micro-operations in complex micro-scale environments.

　　The miniaturization of machines provides a new perspective and an effective tool to explore the micro-world, and the development of micro-nano robot technology is of great significance to explore the mysteries of life. In terms of scientific research and exploration, as one of the important branches of advanced robotics, micro-nano robotics is a new interdisciplinary subject with many major scientific problems and cutting-edge hot technologies, covering physics, chemistry, biology, mechanics, materials science, micro-nano manufacturing, micro-electromechanical systems, robotics, micro-dynamics, microelectronics, information and control, bioengineering, biomedicine, clinical medicine and many other disciplines.

　　Speaking of the history of micro-nano robots, we may date back to the 1960s. Richard feynman, an American theoretical physicist and Nobel Prize winner in physics, first mentioned nanotechnology in a speech delivered at California Institute of Technology on December 29th, 1959. He described this magical technology as follows: "There is enough space at the bottom". This epoch-making exposition not only established the concept of nanotechnology, but also heralded the arrival of micro-nano robots and nano-medicine era.

　　According to Feynman, Albert Hibbs, his doctoral student at that time, first put forward the bold idea of "devouring surgeons" and pointed out that "it may be possible to permanently implant some tiny machines in the body to help some organs with insufficient functions work normally". This "crazy" idea was later adapted into the plot of reducing the submarine to the size of microorganisms and injecting it into the human body to repair brain damage through miniaturization technology, and it was made into the famous sci-fi movie Fantasy Voyage.

　　It is worth mentioning that this idea of entering the body in miniature had a similar plot as early as in The Journey to the West, a book written in the middle of Ming Dynasty in ancient China. For example, the Monkey King turned into a flying insect and drilled into the belly of an iron fan princess, and he could change his size as he pleased. The fairy tale Hu Gong written by Ge Hong in the Eastern Jin Dynasty in China also mentioned a spell similar to miniature space-time: "(Fei Chang) The room has magical power, which can shrink the pulse of the earth and exist thousands of miles away, but it is now natural."

　　Half a century later, in 2008, Feynman’s wonderful idea was finally successfully realized by the research team of Swiss Federal Institute of Technology in Zurich — — Artificial "magnetic mite" The size of this mechanical mite is in the sub-millimeter level. Under the control of high-frequency oscillating magnetic field, the inertial impact generated by the collision of dislocated magnetic blocks is transformed into the forward driving force, so as to realize the precise control of tiny objects. In 2009, the team developed an artificial "bacterial flagella" through the spiral motion of bionic Escherichia coli. This three-dimensional micro-spiral made of nano-heterogeneous film self-curling technology can complete accurate targeted drug delivery under the control of low-field rotating magnetic field.

　　Early research focused more on exploring how to design micro-actuators that convert various forms of energy into mechanical energy, so it is often called micro-nano motors figuratively. In recent years, with the rise of soft materials, micro-nano additive manufacturing and artificial intelligence, micro-nano robotics has begun to develop from a single structure to an intelligent direction to adapt machines to micro-scale complex environment and multi-task requirements.

　　Nowadays, the research of micro-machine intelligence has taken shape, including micro-power and precise operation, micro-mechanical gain, software adaptability, flexible continuum, modular reconstruction, information storage and processing, hybrid hybrid advantages, bionics and optimization, micro-system integration, self-organizing interaction and swarm intelligence, and molecular self-assembly/replication/growth. At present, the most advanced work in this field is trying to explain or solve the core problem of how to give machines real intelligence at the micro scale, which points to the ultimate goal and the highest stage of micro-machine functionalization: micro-machine intelligence or micro-scale artificial intelligence.

　　It has broad application prospects.

　　In recent years, the emerging advanced materials and nanotechnology have promoted the rapid development of micro-nano-science. The research involves many frontier directions, such as controllable self-assembled molecular motors and DNA origami at molecular level, composite mechanical transmission devices at micro-nano scale, reconfigurable flexible variant micro-machines, hybrid electromechanical systems, integrated micro-electronic micro-machines, interactive nano-brain-computer interfaces, and millimeter-scale micro-robots such as flapping-wing mechanical insects. These artificial micro-machines have the unique advantages of small size, non-destructive and minimally invasive, ultra-light and portable, accurate control, high functional integration, easy to manufacture on a large scale, and micro-scale performance such as ultra-high sensitivity and responsiveness, enhanced stability and robustness, and extremely low energy consumption, which has an irreplaceable role in promoting technological innovation and scene expansion in many fields such as precision medicine, environmental engineering, intelligent manufacturing, life sciences and artificial intelligence.

　　In medicine, micro-nano robots have great potential in precision medical fields such as minimally invasive intervention, targeted delivery, rapid treatment, early diagnosis and tissue repair, such as using micro-nano robots to enter liver and kidney tumors, cerebral aneurysms, peripheral tissues and organs, embolizing and removing thrombi from micro-blood supply arteries, entering and accurately manipulating the central nervous system through subarachnoid space, realizing pain control in the treatment of advanced cancer, and monitoring physiological signs in vivo using implantable multi-sensor systems.

　　In addition, micro-nano robots can also play an important role in environmental engineering fields such as river and sea sewage purification, air pollution prevention and control, biodegradation and catalysis. Driven by the external field, these micro-agents can organize themselves to move in groups, so as to accurately control the local flow field micro-disturbance, make a directional response to specific environmental conditions, and selectively identify pollutants by carrying, transporting and releasing biological enzymes or catalysts, so as to speed up the reaction process and greatly improve the efficiency of capturing, removing, degrading or repairing pollutants such as organic molecules, toxins/nuclides, marine oil pollution, pathogenic microorganisms, microplastics, heavy metals and radioactivity.

　　Because of its small size, micro-nano robots have high spatial freedom and super-redundant dexterity, and can dive into the limited space that traditional robots can’t reach to complete fine operations. They have unique advantages in high-end equipment manufacturing fields such as complex three-dimensional metamaterial processing, microelectronic circuit assembly and packaging, and detection and maintenance in micro-cavities. It is particularly noteworthy that whether human beings can build an intracellular "protein synthesis factory" on a micro scale depends on how to construct a highly recognizable DNA code for the controllable assembly of amino acids to accurately guide the orderly synthesis of protein. Previous studies have shown that nano-magnetic editing technology can embed multi-modal variant information into micro-machines with nanometer precision, and its more important value lies in that base pairing similar to DNA double helix can be constructed by using nano-magnetic coding. Therefore, organizing the division of labor for micro-nano robots can efficiently and orderly assemble all kinds of functional micro-units, and it is expected that this technology will be used to truly realize the "micro-machine factory" from "machine manufacturing machine" in the micro-scale.

　　Of course, the stage of micro-nano robot is far from this, and it has unlimited potential for various practical applications. We can’t find ideal answers to many questions now, but each question is so fascinating: can DNA molecular computers surpass quantum computers? What is the minimum size of a micro air vehicle, micron or even nanometer? What is the physical limit of artificial intelligence? Is the smallest agent unit a single molecule of hydrogen and oxygen? Nano-doctor and long-term in vivo implantation, nano-brain-computer interface and precise manipulation of single nerve, and how to realize cross-scale interaction … … The resulting revolutionary subversion technology will be the potential development direction of micro-nano robots in the future.

　　Micro-nano robots have not only existed in science fiction movies, but scientists from all over the world are actively pushing them from basic research to real practical application scenarios. People are full of reverie and expectation that it will benefit mankind and transform the world one day. Nevertheless, we need to be soberly aware that the field of micro/nano robots has just started, and the extensive interdisciplinary will bring more thorny problems of integration and innovation. It is also necessary to actively guide scientists in the forefront of different disciplines to tackle key problems in depth and rapidly promote the high-quality development of micro/nano robots at the national level. In order to develop advanced micro-nano manufacturing and robotics for the next generation of intelligent micro-machines, we should be guided by the major national demand, incite the intellectualization and miniaturization of machines, equipment and systems, focus on exploring the basic theory and key technologies for the intelligent realization of micro-machines, promote the rapid development of micro-nano robots, seize the commanding heights of science and technology, and safeguard the core interests of the country.

The box office does not mean that all movies still need masters.

　　1994 was a magical year in the world film history, with many excellent works shining in the film history. Around that year, China’s film moderns, Chen Kaige’s Farewell My Concubine won the only Palme d ‘Or in China, Zhang Yimou’s Alive won the Best Actor, and Jiang Wen’s first novel Sunny Days won the national box office championship. The three men are not independent figures, but they are great masters among directors. However, in the past two years, the market performance of the three masters’ works is average, as if there is always a red line that can’t be crossed. Zhang Yimou’s Shadow and Jiang Wen’s Evil Doesn’t Suppress Righteousness are hovering around 600 million, and Chen Kaige’s The Legend of the Demon Cat is about 500 million. Now, when the box office of big movies starts at 1 billion, the box office performance of the masters is really not bright enough. Objectively speaking, these three films are also excellent in quality among domestic films. Why are they not popular in the market?

　　All three masters have it.

　　Extraordinary artistic originality

　　It is thankless to compare these three people. We only analyze their most distinctive artistic features.

　　Cultural reflection has always been the label of Chen Kaige. A good family origin, at the same time, has experienced the pressure of the times and system, which makes Chen Kaige teenagers mature and like to think about the advantages and disadvantages of China’s traditional culture and reflect on historical lies. The Yellow Land shows the individual’s numbness under the loess culture for thousands of years. king of the children, Grand Parade, Singing while Walking and Jing Ke Stabbing the King of Qin are all full of reflections on the ills of the times, collectivism and even nationality. He was obsessed with cleanliness and finally reached the peak in the epic narrative of Farewell My Concubine. But when Chen Kaige wants to wake up from the introspection and torture of traditional culture and focus on the present, it is not very harmonious — — The Promise became the greatest shame of the master, the artistic level of The Orphan of Zhao was lower than expected, Search failed to grasp the essence of realism, and The Taoist Down the Mountain made it worse. You can’t say that Chen Kaige didn’t think, but his thinking is difficult to have a dialogue with the audience.

　　Zhang Yimou is best at color control. From the beginning of "Yellow Land", it shows amazing control over pictures and colors. "Red Sorghum" is the first film directed by him. In this film, there is a strong tension between the grand narrative of history and the exaggerated folk imagination, and the image style is very wild. This wanton and enthusiastic color obsession has been maintained until now. In the early days, Zhang Yimou was very "rustic" and liked to shoot rural subjects. He was deeply influenced by neo-realism. In "story of qiu ju" and "None Less", the cultural consciousness and responsibility of the fifth generation were very obvious in him. However, Zhang Yimou’s second identity is the initiator of domestic blockbusters. Hero has laid the basic paradigm of blockbusters, but he has also been accused of artistic depravity since then. The Golden Flower in the City, The Surprise of Three Guns and The Great Wall have come all the way, and the box office is very high, but the artistic exploration has stopped.

　　Jiang Wen is a very special existence. As the "Kusturica of China", he is the wildest director of China, but he has not been burdened with the shackles of reflection on the cultural consciousness of his home country. On the contrary, he always looks at history with a playful attitude, and is a true descendant of Dionysian spirit. Sunny Days beautifies the turbulent times with filters, focusing on human freedom and nature in history. The absurd black humor in The Devil Comes is basically unmatched in China, but who can say that this is not true history? In The Sun Also Rises, there are even more madness. The train tracks give birth, crazy mothers climb trees, and cobblestone rooms by the river. Metaphors are everywhere, reflecting the absurdity of the times through the absurdity of individual life. Jiang Wen’s greatest feature is that he is unconstrained style, and he is good at "drama", and the most serious history can also be teased. One Step Away and Evil Doesn’t Suppress Righteousness like to take the historical background as the stage, so that the forces of all parties can take turns to go into battle, the conflict is fierce, and the larger foe is broken. Finally, the sunset is left and the hero disappears.

　　It can be said that the artistic originality of the three masters has become the most fundamental guarantee for them to achieve the status of rivers and lakes, but will this originality diminish with the passage of time and can the audience feel it every time? No one can guarantee these.

　　What have the three masters met now?

　　The most important keyword in China movies in recent years is fast. Movies are commodities, not lofty arts. Generation division is gone, and the generation division directed by China will end in the sixth generation forever. On the one hand, the sixth generation of artistic features are doomed to be unable to become the mainstream of the market and to shoulder the great responsibility; On the other hand, the new generation of directors can’t divide by generations, and the threshold of directors has long been so low that everyone seems to be able to do it. Zhang Yimou has been dissatisfied with this. These new generation directors no longer have unified academic characteristics and a unified sense of cultural mission. Their first task is to win the market, that is, to win the hearts of the audience, so they need to do everything they can to prove their ability to investors and gain a foothold in the market. In this environment, the Zhang Yimou people may not be able to cope with the fist and fist kung fu.

　　For example, there are comedies, which have always been the most popular in the market. Under the background of the gradual decline of Hong Kong comedies, domestic comedies are experiencing explosive development. It seems that Bo Huang, Xú Zhēng and Wang Baoqiang are all comedies’ successors. It is precisely this kind of film that Zhang Yimou, Chen Kaige and Jiang Wen are not good at, because comedy needs genes. Jiang Wen is the best of the three masters. As long as he does comedy seriously, it will be powerful, and the opposite is Waterloo. The sense of comedy in Let the Bullets Fly is natural, close to history and very modern, with great influence; What impressed me the most in Evil Doesn’t Suppress Righteousness is "Zhu Yuanzhang’s Portrait" and "Chiang Kai-shek’s Diary". Although they have their own personal interests, they are not inferior. Zhang Yimou also did the urban comedy "Let’s Talk Well", but he just played with tickets. As the name of the Buddhist master became more and more popular, he became less and less diligent in comedy. Chen Kaige basically doesn’t make comedies, because he is too serious and deep. Maybe comedies don’t fit his position.

　　There are also war movies. Wolf Warriors 2 is an insurmountable box office champion in domestic movies. Unfortunately, none of these three masters have any real war films. Others are detective mystery films, youth campus films and tomb raiding magic films, among which the best ones have higher box office than the three directors, but can you say that the three directors are inferior to them in artistic cultivation and directing skills? On the contrary, if the three masters did not make serious mistakes, their quality was basically guaranteed. For example, Chen Kaige’s "The Legend of the Demon Cat" has a grand historical narrative pattern. Through a peek at the literary truth, it shows the spirit of the prosperous Tang Dynasty and the lie logic that is kept secret, which is an accurate restoration of the traditional meaning. Zhang Yimou’s Shadow, a traditional landscape painting style, presents China’s traditional cultural symbols and traditional artistic conception to the extreme, which is unmatched in domestic films. Jiang Wen’s "Evil Doesn’t Suppress Righteousness" adapted the original text with a single theme of revenge into a distinctive hodgepodge of the Republic of China, and the complex historical metaphor clues and imaginative imagination were integrated, which others really couldn’t shoot. At this time, the master was the master.

　　Is that because they don’t like the box office? In fact, none of the three directors dare to say that they never consider the market. On the contrary, I think they have been actively embracing the market now. When Zhang Yimou filmed "The Great Wall", he said bluntly that he wanted to make a popcorn movie. Chen Kaige also filmed Search, an adaptation of an online novel, trying to get close to the audience. Jiang Wen’s "One Step Away" and "Evil Doesn’t Suppress Righteousness" try to give up the overly artistic narrative style, but the market effect is not ideal. The reason is that the changes of the times have brought about changes in popular culture, market needs and audience aesthetics are changing. The question is: can the masters still accurately touch the audience’s high points now?

　　Box office is not everything.

　　Movies still need masters.

　　Benjamin mentioned the concept of "halo" in "Works of Art in the Age of Mechanical Reproduction" — — That kind of authenticity, uniqueness, sacredness and sense of distance. Halo can be a specific feature of a work or a unique atmosphere of an era. In the era of large-scale mechanical reproduction of art, the halo of traditional classic works of art is gradually disappearing. Why is it so difficult to have the masterpieces of the former European masters now? Do we still need masters in this era?

　　This year is recognized as a small year of film and television, and the explosion of film and television is mostly due to the pursuit of the so-called "cool", upgrading and fighting monsters, and being pleased with the enmity, invincible and countless fans. The pursuit of flat narrative is a trend of world film and television, especially represented by Hollywood blockbusters, which is invincible all over the world. This is understandable. In fact, this is an inevitable trend of the development of popular culture. As Wang Yichuan, a scholar, said in The Myth of Zhang Yimou: The End and Its Significance: When the film art no longer takes poetic enlightenment as its own responsibility, but takes commercial success as its basic goal, the enlightenment culture will have to taste the bitter fruit of defeat. The end of Zhang Yimou myth indicates that the enlightenment myth and personality myth of intellectuals came to an end in 1980s, and reveals the inevitability of the transformation of enlightenment culture into mass culture.

　　As a popular culture, movies have been subdivided in the current China film environment, and there are still boundaries between art films and commercial films. The perfect combination of business and art is every director’s dream, but such works are rare all over the world, and the Palme d ‘Or works at Cannes Film Festival can’t bring you huge box office. However, this does not mean that the film art must be flat. Chen Kaige, Zhang Yimou and Jiang Wen’s artistic originality may not be at its peak, but the works they create with their heart will immediately make waves like boulders as long as they pass through the market. Once again, "Evil does not suppress righteousness" strongly publicizes the Dionysian spirit full of hormonal narrative passion, and "The Legend of the Demon Cat" reveals the deep core of traditional culture. Although these two films failed to achieve the box office results of commercial blockbusters in the same period, they will eventually be proved by history.

　　After more than ten years of marketization, China’s films have developed rapidly in industry, and commercialization has been immersed in China’s films. However, the film market has cooled down this year, indicating that industrialization cannot solve all problems, and the market needs good works. On the one hand, good works need the accumulation of industry, on the other hand, the accumulation and inheritance of art are inevitable. Every era needs Chen Kaige, Zhang Yimou and Jiang Wen of every era. In fact, China’s film art exploration has not stopped. More new generation art film directors, such as Bi Gan and Xin Yukun, are also emerging, bringing hope to domestic films. The times need masters of art, but they need different artistic originality continuously.

　　It is said that Zhang Yimou’s first film "Red Sorghum" will be released again this year. How many people will go to see this Jiang Wen’s fifth-generation masterpiece, which really brought China movies to the world? This can be regarded as a test of the China film market, as well as the film audience. (Hu Xiang)

Retail flameout, force on the public？

Text/"Tsinghua Financial Review" Bai Haochen

In 2024, commercial banks have not got rid of the quagmire of retail stall.

Recently, the annual reports of most state-owned and joint-stock banks in domestic listed banks have been released. The annual report shows that the growth rate of net profit of state-owned banks and stock banks has generally slowed down, and some institutions have even experienced a significant decline. For example, the net profit of Minsheng Bank has shrunk by 9.85% compared with the previous year, and Ping An Bank has dropped by 4.19%.

In terms of revenue, according to the business caliber, the classified revenue of the counted commercial banks is very different. Among the state-owned banks, Industrial and Commercial Bank of China and Bank of Communications account for a relatively large proportion of public business revenue, while the retail business of agriculture, construction, China and postal services exceeds public business. Among the stock banks, CITIC Bank, Minsheng Bank, Shanghai Pudong Development Bank and Zheshang Bank account for a relatively large proportion of corporate business, while the retail business of China Merchants Bank, Ping An Bank and China Everbright Bank exceeds corporate business.

Judging from the change of revenue, the performance of commercial banks in public business revenue is generally better than that in retail business. In terms of retail business, the retail business income of most commercial banks has decreased compared with the previous year, and only a few banks have achieved growth. In particular, the retail business of Ping An Bank, China Everbright Bank and Shanghai Pudong Development Bank declined significantly. The retail business income of Ping An Bank dropped by 25.90% to 71.255 billion yuan, while the decline rate of Shanghai Pudong Development Bank and China Everbright Bank also exceeded 10%.

In terms of public business, more than half of the listed banks achieved growth in 2024, while the banks that did not achieve growth did not experience a sharp decline. The largest increase in corporate business was Ping An Bank. Although the retail business shrank sharply, its corporate business increased by 19.15% in 2024, and its revenue to the public was 63.841 billion yuan during the year. Postal Savings Bank, Zheshang Bank and Shanghai Pudong Development Bank are also growing significantly on the public side.

Looking at the profit again, according to the business caliber, in 2024, the profit performance of corporate business is also significantly better than that of retail business. In terms of retail business, except for workers and peasants China Construction and China Merchants Bank, the retail profits of other banks are very small, and Zheshang Bank even experienced retail losses, with a loss of 2.663 billion yuan during the year. The performance of corporate profits is satisfactory. Except for some large state-owned banks or those banks featuring retail business, corporate business has become the main pillar of bank profits.

Figure 3: Profits/losses of some state-owned and joint-stock banks in 2024 (broken down by retail size, RMB 100 million)

In terms of profit changes, in 2024, the profit points of most banks have obviously shifted-the profit of corporate business has increased rapidly, while the profit of retail business has dropped sharply. In terms of retail business, the retail profits of listed banks generally declined compared with the previous year, among which Everbright Bank and Ping An Bank declined significantly, and Everbright Bank decreased by 95.83% to 281 million yuan. Ping An Bank dropped by 94.81% to 356 million yuan. On the public side, most banks’ profits have improved, and there are not a few that have greatly improved. In 2024, the profit of the Agricultural Bank of China to the public increased the most, with an increase of 68.92% to 244.892 billion yuan during the year. China Construction Bank, Industrial and Commercial Bank of China, Bank of China and China Merchants Bank also increased by over 20%.

Figure 4: Changes in profits of some state-owned and joint-stock banks in 2024 (split by retail size)

In terms of characteristics, both revenue and profit show the trend of corporate expansion and retail contraction, or it can be explained as the strategic turn of bank operation. The reason is mainly the cyclical rotation of bank retail and corporate business-in the past, retail business performed strongly and was under pressure on corporate business, but now it is in the opposite form.

In the early years, China’s banking industry was dominated by corporate banking. After 2010, the background of interest rate marketization superimposed residents’ wealth accumulation and consumption upgrading, prompting commercial banks to shift their strategic focus from corporate to retail. With the optimization of the top-level design of retail business, such as the pilot expansion of consumer finance companies, the relaxation of credit card installment business supervision, and the gradual improvement of personal credit information system, in 2016, joint-stock banks led by China Merchants Bank and Ping An Bank took the lead in the wave of the development of retail business characteristics, subverting the traditional business logic centered on corporate business and upgrading retail business to another growth pole of commercial banks besides corporate business.

Based on a huge customer base, retail business can provide considerable business volume, and because of the high basic interest rate of retail loans, it can also alleviate the pressure of bank interest margin, which is one of the best tracks for commercial banks to enhance their profitability and improve their operating level. Under the background of "expanding domestic demand and promoting consumption", the value of retail business is rising, and its importance is becoming more and more prominent. Commercial banks have also carried out retail business transformation in order to adapt to macro-development, alleviate the current operating difficulties, occupy a favorable position and seize the first opportunity in industry competition.

However, in recent years, the retail business of banks has gradually entered a bottleneck period. Since 2023, commercial banks have been in a state of collective stall at the retail end for two consecutive years. According to incomplete statistics, the retail revenue of most large and medium-sized banks that have published results has been hit, and the retail business revenue has generally shown a negative growth trend. There are two main reasons for the huge decline in retail business of commercial banks:

On the one hand, the downward cycle of real estate continues to curb residents’ willingness to consume. After decades of prosperity, China’s real estate market suffered periodic pains, and the growth rate of national real estate development investment declined for three consecutive years. The downward trend of the housing market had a direct impact on residents’ asset value and income expectations. First, the shrinking asset value directly affects residents’ willingness to consume. In order to cope with potential economic risks, more residents tilt their financial focus from consumption to savings, which inhibits mainstream personal credit businesses such as credit cards and consumer loans. Second, the continuous decline in housing prices will continue to hit the confidence of mortgage buyers and raise the risk of default, which will lead to a surge in non-performing rates.

On the other hand, credit cards, consumer loans and other products face high homogeneous stock competition. After years of market development practice, China’s urban credit card and consumer loan markets are gradually saturated. At present, the retail product matrix of each bank is highly homogeneous, and it mainly relies on the preferential strength and location advantages of commercial banks for stock competition. In addition, with the rise of internet finance, online consumer credit products, with their convenience and flexibility, further aggravate the operating pressure of credit card and consumer loan business. According to the Blue Book of China Bank Card Industry Development 2024, the total amount of credit card transactions in 2023 was 39.8 trillion yuan, a year-on-year decrease of 5.6%, and the transaction amount declined for two consecutive years. The average decline of credit card transactions in state-owned/joint-stock banks has reached 23.44%. With the stall of the main retail businesses such as credit cards and consumer loans, the growth momentum of bank retail has fallen into a bottleneck.

Under the long-term influence of multiple factors, the non-performing rate at the retail end of banks has risen and the incremental space has been continuously compressed. Under the realistic background that weakness is difficult to solve in a short time, commercial banks need to resort to other businesses to ensure high-quality and stable operation.

The performance of the public business is bright, and the bank’s break is dawning.

In the context of the collective stall of retail business of commercial banks in 2024, the resilience shown to public business may become the way to break the bank’s operation. For a long time, corporate banking has been an indispensable part of bank credit business, although in recent years some banks have shifted their focus to retail business. However, the foundation of public business is still there. In the context of the current lack of growth momentum of retail business, it is relatively wise for commercial banks to shift their business focus to corporate business, which is embodied in the following points:

First, it has strong anti-cyclical ability for public business. Compared with the retail business, which is highly influenced by the fluctuation of economic cycle, the public business has stronger anti-cyclical ability relying on policy support and industrial chain coordination. The stability of corporate customers’ cash flow is higher than that of retail customers, which plays a role in smoothing the fluctuation of asset quality in the overall operation of banks.

Second, the corporate business has more abundant business scenarios. Corporate business has the nature of "credit+",while corporate business has the nature of "credit+",which can promote the coordinated development of intermediary business, thus generating the multiplier effect of comprehensive income. By providing services to corporate customers, banks can simultaneously explore retail business opportunities such as payroll and employee wealth management, and realize the value transfer chain from enterprises to individuals to enterprises.

Third, the development of corporate business is in line with the current policy orientation. Under the current macroeconomic policy environment, the state emphasizes that finance supports the real economy and promotes industrial upgrading and structural adjustment. As one of the core channels of banking service entities, corporate business is highly compatible with policy guidance such as serving the real economy and supporting national strategic industries, which not only helps banks optimize their credit structure, but also effectively connects with national policies and helps the rapid development of national strategic industries. By developing corporate business, banks can deeply understand the needs of enterprises and provide customized financial services, thus promoting industrial upgrading and high-quality economic development. At the same time, the development of public business can also promote the development of related industrial chains, form a virtuous circle and inject new impetus into economic growth.

Two-wheel drive for public retail, and banking is not biased.

Ji Guangheng, president of Ping An Bank, said at the performance meeting that no strong bank was biased in the end. Without development loans, there will be no mortgage. Without a new account, there will be no waiting list. We still have a process of balanced development. In fact, corporate and retail businesses are not binary opposites, but more like two sides of banking business. Corporate businesses can naturally penetrate the upstream and downstream small and medium-sized micro-customers and employees’ personal financial service needs by serving the core enterprises in the industrial chain; The consumer behavior data accumulated by retail business can feed back the bank’s accurate judgment on the operating conditions of corporate customers.

Looking forward to the future, commercial banks must adhere to "walking on two legs" in order to achieve high-quality development. We should not only deepen the basic advantages of retail business, but also grasp the strategic opportunities of public business. This two-wheel drive business model is not only a pragmatic choice to meet the current challenges, but also a long-term plan for the future.

　　Returning to prison again, Liu Fan (a pseudonym) has some feelings.

　　"Is the company’s income high?" "How do you get along with your colleagues?" … … Under the rostrum, former prisoners kept asking questions.

　　This time, Liu Fan, who participated in the on-site simulated job fair for returnees of Guanghua Prison in Shayang, Hubei Province together with the person in charge of the company, turned into an "interviewer". Liu Fanfan is a released prisoner in Shayang Guanghua Prison. Recommended by the prison police, he entered an electronic product production company in Guangdong, and now he has become the technical backbone of the company.

　　"Being educated and reformed in prison has made my life start again, and the trust and support of the company have given me new life opportunities." Liu Fan said.

　　It is a concrete manifestation of Shayang Guanghua Prison’s practice of the new concept of "five major transformations" to "open" the job fair into the prison and invite released prisoners to show up.

　　On January 4th this year, Hubei Provincial Prison Administration held a meeting to promote the pilot work of "Five Major Reforms" model prisons in Shayang Guanghua Prison, and summarized the working experience of each pilot prison. In order to implement the new requirements of the Ministry of Justice on the "Five Major Reforms" of prison work, which is "guided by political reform, promoting supervision reform, education reform, cultural reform and labor reform as a whole", in 2018, the Party Committee of Hubei Provincial Prison Administration deployed and carried out pilot projects of demonstration prisons with the "Five Major Reforms" as the main contents in Shayang Guanghua Prison, Xianning Prison, Hanjiang Prison and Huangzhou Prison.

　　"With the combination of point and surface, we will first grasp the pilot demonstration and then fully promote it in the province." Hao Aimin, secretary of the Party Committee and director of Hubei Prison Administration, said that this is a working idea and an important measure for the prison system in Hubei Province to stick to the bottom line of safety, practice the purpose of reform and promote the new pattern of "five major reforms" as a whole.

　　Political culture infiltrates into the prison area, political books cover into the prison house, political reform day study week gives comments, and the warden gives the new prisoners the first lesson of political reform … … Over the past year, the Hubei Provincial Prison Administration has held three seminars on model prisons, set up a leading group and office for the creation of model prisons, and formulated and promulgated the Implementation Plan for the Pilot Work of Hubei Model Prison. Four pilot prisons, including Shayang Prison Administration, have deployed elite forces to set up special classes to carry out their work.

　　Nowadays, four pilot units of model prisons have explored their own unique transformation models — —

　　Shayang Guanghua Prison adheres to the guidance of party building, and comprehensively implements the "five-oriented" transformation model of transparent, standardized and refined management, systematization of political transformation, permanence of team institutions, classroom-based learning and education, routine education reform and effectiveness of assessment and evaluation; Xianning prison fully implements the standardization of all work, and actively constructs a new management mechanism of grading and handling in charge of detention, an incentive mechanism for penalty execution, a new labor reform and correction mechanism and an innovative mechanism for educational reform; Huangzhou Prison promotes the reform of the prison area system, dividing the prison area according to the floor, effectively improving the prison safety factor and promoting the flat and scientific prison management; Hanjiang Prison, as a demonstration prison for Internet application determined by the Ministry of Justice, realizes standardization of hardware facilities and intelligent on-site management, and the standardized management of labor sites is at the forefront of the country.

　　As small as a toothbrush and a pen are shortened; The water temperature of prisoners’ drinking water should be controlled at about 70 degrees after boiling, so as not to hurt people by boiling water … … During the observation in Shayang Guanghua Prison, the small details carefully set in the prison area won praises from the participants.

　　"In order to strengthen political reform, we require prisoners to take political reform classes from the time they enter the prison, regularly raise the national flag, watch red movies, and also hold activities such as theme essay writing and red song contest, so that political culture can enter the prison area and enter the prison house, realizing full coverage of the whole process of political reform." Zhang Rongsheng, Party Secretary and Warden of Shayang Guanghua Prison, introduced.

　　Statistics show that in 2018, the number of criminals violating discipline in Shayang Guanghua Prison decreased by 13% year-on-year, and the number of people taking the high school entrance examination increased by more than 7 times year-on-year.

　　In an interview with the reporter of Legal Daily, Xiong Hao, secretary of the Party Committee and director of Xianning Prison, said that in order to improve the ability and level of promoting the "five major reforms", Xianning Prison divided the police into three categories: supervision reform, education reform and labor reform, and classified the selection and employment, education and training, evaluation and assessment, and the professional level of the police continued to improve.

　　"The pilot demonstration prison is an important measure to implement the work deployment of the Ministry of Justice, an important content to implement the comprehensive deepening reform work of the Hubei Provincial Party Committee, and an important starting point for promoting prison work." Hao Aimin said that in the next step, the province’s prison system will set an example in nine aspects, such as improving the quality of prisoners’ reform, standardizing law enforcement, intelligent construction, reform and innovation, cultural construction, party building and discipline style, so as to continuously improve the overall management level of prisons.

China Vaccine Helps Global War ＂Epidemic＂

　　"China will step up its efforts to provide 2 billion doses of vaccine to the world throughout the year, deepen cooperation with developing countries in fighting epidemic diseases, and make good use of China’s direction ‘ COVID-19 Vaccine Implementation Plan ’ The donation of 100 million US dollars has made due contributions to mankind’s complete victory over the epidemic. " On September 17, the Chairman of the Supreme Leader made a solemn commitment when attending the 21st meeting of the Council of Heads of State of the Shanghai Cooperation Organization member states by video in Beijing.

　　△ On September 17th, the Supreme Leader of president attended the 21st meeting of the Council of Heads of State of SCO member states by video and delivered an important speech.

　　At present, Covid-19 mutates frequently, and the epidemic situation is still delayed and repeated around the world. It is necessary to speed up vaccination and let the construction speed of group immune barrier run ahead of the spread of virus variation. However, the global vaccination imbalance is still outstanding, and the international community expects more confidence, hope and cooperation.

　　Since the beginning of this year, the Chairman of the Supreme Leader, standing at the height of seeking health for mankind and development for the world, has repeatedly expounded China’s proposition at international conferences and other important occasions, led China to fulfill its commitment to make vaccines a global public product, and practiced the concept of human health community with practical actions — —

For many developing countries, China vaccine is the first batch of vaccines.

　　In order to realize the accessibility and affordability of vaccines in developing countries, China has also actively promoted the localization of vaccines in other countries.

Protecting the mental health of children and adolescents

　　Guangming Daily reporter Yan Xiaoyan

　　For some time, teenagers’ mental health problems have attracted much attention. The topic of "Mom stopped taking antidepressants for her daughter and replaced them with vitamins" triggered a continuous discussion among netizens: "Why don’t parents pay attention to their children’s emotional changes?" "Why are many children unhappy now?" Previously, the Hu Xinyu incident triggered profound reflection from all walks of life.

　　"Depression, each of us will have in our lives, but what are the specific symptoms of depression, how to detect it, which requires professional identification. In this regard, our ordinary people’s cognition is lacking. " Mao Min, a psychological teacher at Beijing Jingshan School, told reporters.

　　What should we do for children? How to hear the children’s cry for help and reduce the occurrence of tragedies? The reporter interviewed relevant experts to find the answer together.

　　Cognition of distress signals — —

　　"Depression" is often mentioned, but the public is not familiar with its performance.

　　"Early detection, early warning and early intervention." This is an important thing for many psychologists. Treating mental health problems, timely detection, timely intervention and non-intervention, the consequences are obviously different.

　　According to the relevant documents, all high schools and institutions of higher learning have set up psychological counseling (consultation) rooms and mental health education courses, equipped with mental health education teachers; Incorporate depression screening into the content of students’ health examination, establish students’ mental health files and evaluate students’ mental health status. The word "depression" is often mentioned by everyone, but the public is not fully familiar with the related knowledge of depression and mental health.

　　As a parent or teacher, what performance should we focus on? Front-line psychological educators usually pay more attention to students when they have the following "signals":

　　Academic signal: sudden or continuous decline in academic performance; Inattention in class; Often do not hand in homework or hand it in late; Excessive demands on teachers’ time and attention; The content of homework (composition) is abnormal; Internet or mobile phone addiction, unable to study and live normally.

　　Physiological signals: obvious changes in appearance, such as sudden weight loss, untidy clothes, and lack of attention to personal hygiene; Abnormal diet and sleep; Easy to fatigue; Absent-minded in doing things; Vague and illogical speech; Acting strangely and divorced from reality; Have hallucinations or delusions.

　　Psychological signal: family problems, interpersonal setbacks or adjustment difficulties are being encountered; Self-exposure of personal bad mood or mental crisis; The reaction to the event is not normal compared with others; Too much crying or too much panic; Irritable; Language violence; Unusually indifferent; The group around the student expressed their concern.

　　Security risk signal: unprovoked anger or hostility; Physical violence; Hint or directly threaten others; Homework and test papers express a strong sense of hopelessness, anger, worthlessness, isolation, despair, self-injury and suicidal thoughts or behaviors; Stalking or harassing others.

　　"Of course, there will be psychological evaluation, but the evaluation is only a reference, and it is still necessary to make a comprehensive judgment according to the actual situation of the child. School psychological teachers have no right to diagnose psychological problems, which require the intervention of professional doctors. " According to Mao Min, there are several prone periods of mental health problems, such as entering higher school, the eve of graduation, before and after exams, and when students have major life events while growing up.

　　Not long ago, the Institute of Psychology of the Chinese Academy of Sciences and Social Science Literature Publishing House jointly published the third blue book on mental health in China, in which the special report "Investigation Report on Adolescents’ Mental Health in 2022" was reported, and more than 30,000 primary and secondary school students aged 10-16 in 29 provinces (autonomous regions and municipalities directly under the Central Government) were investigated. The results show that about 14.8% adolescents have different degrees of depression risk, among which 4.0% adolescents belong to the risk group of severe depression and 10.8% adolescents belong to the risk group of mild depression.

　　"Both teachers and our parents should be vigilant. Don’t think that these mental diseases or depression and anxiety are far away from us. Each of us may suffer from these diseases. Even if we don’t reach the level of the disease, we may be troubled by these negative emotions. This point still needs attention and vigilance. " Liu Yanru, a clinical psychotherapist in huilongguan hospital, Beijing, said.

　　"Some children have suicidal thoughts and even put them into action, but they are still afraid to ask others for help." Liu Yanru believes that "children don’t make a sound, which requires our parents and teachers to consciously take the initiative to pay attention to these children, see if they behave differently from others, or are obviously different from his original personality, and ask them what happened. If we can’t solve it, we can ask professionals for help. "

　　Cognition of mental illness — —

　　Mental illness can be treated, and there is no need to avoid medical treatment.

　　"Seven or eight-year-old children say that they are in a bad mood and unhappy, and they want to find a psychologist. Some parents will think that children are joking, and they are full of food and drink every day, which is like depression. " Liu Huaqing, chief physician of huilongguan hospital Children’s Psychology Department, feels that parents can’t recognize it, and casually deny that they may have inadvertently overlooked that the child is in pain.

　　In the daily outpatient service, Liu Huaqing clearly felt that there were more adolescent patients coming to see a doctor than before. He reminded parents to learn about depression, not to criticize or blame, but to accept and understand their children’s pain.

　　What psychological problems do children usually have in campus psychological counseling?

　　Mao Min introduced that in the primary school stage, the first and second grade students mainly adapt to the problem. General adaptation problems are divided into two categories: one is that students’ own development level is not enough to cope with primary school learning. There are grade one and grade two students who have attention deficit and are diagnosed by the hospital as ADHD, dyslexia and dysgraphia, etc. problem children; One is that they have not developed good rules and habits, and their self-care ability is relatively weak. In the middle and senior grades of primary school, students encounter more and more interpersonal problems. "In junior high school, it is emotional management, interpersonal communication, internet use and academic problems. In the eighth and ninth grades, facing the senior high school entrance examination, academic problems are more prominent. In the high school stage, the common problems of students are academic anxiety, self-cognition and interpersonal communication. These problems are often intertwined and affect each other. " Mao Min added.

　　"When students have serious psychological problems and need parents’ cooperation, they are sometimes hindered." Mao Min bluntly said that in real life, some parents are worried that if a child goes to see a psychologist, the classmates will have an opinion on him and will it affect his communication with classmates. At the same time, will children feel abnormal, thus bearing great psychological pressure. There are also some parents who have many practical difficulties in seeking psychotherapy, such as what kind of institution or hospital to choose, as well as the cost and time, which also makes it impossible for individual parents to seek professional help in time and smoothly.

　　As a psychological teacher, he can usually provide psychological counseling for students with general developmental problems. For students with serious psychological problems, parents are advised to take their children to the hospital in time for diagnosis and treatment. In this way, children can get timely help and recover as soon as possible. Mao Min told reporters that benefiting from the linkage mechanism of medical education, Dongcheng District Education Committee and Anding Hospital Adolescent Mental Health Center, where Beijing Jingshan School is located, implemented medical education linkage to provide a green channel for students’ mental health.

　　"It is also difficult for some parents to accept that their children are sick, especially mental illness, which seems to be a disgraceful thing. Parents are deeply frustrated when their children are ill. " Liu Yanru told reporters, "Some people still discriminate against mental illness and are stigmatized. We need to do some popular science to let more people know that even if there is such a disease, it can be treated, and there is no need to avoid medical treatment. "

　　Understand growth and observe carefully — —

　　Give children more love and companionship with a more scientific educational concept.

　　Liu Huaqing bluntly said that in today’s rich material life, although children don’t worry about eating and drinking, they are facing greater competitive pressure for further studies, and their living environment may be more complicated than that of their parents in childhood. At the same time, many young parents are not fully prepared, and they still continue their parents’ views on educational concepts. As a result, "problem" teenagers surfaced.

　　Tang Qianyun is a psychological teacher in Qiyang No.1 Middle School in Hunan Province. There is a standardized psychological counseling center in her school. At least two teachers are on duty every day, and they accept students’ recess appointments and telephone appointments at a fixed duty time.

　　"In response to students’ various psychological puzzles, psychological teachers generally take psychological classes as the basis, and let students learn how to adjust in the classroom. If a few students can’t solve them, they will make an appointment for psychological counseling. In the counseling center, psychological teachers guide students to see problems and find strength from themselves to solve them. Mental diseases beyond their ability will communicate with students and parents in time, and it is recommended to refer them to professional hospitals for detailed examination and treatment. " Tang Qianyun said, "However, from what I have learned from my peers in other grass-roots schools, the teaching staff and school-running conditions of grass-roots rural schools are still limited, and full-time psychological teachers will be transferred to Chinese mathematics courses; Some school leaders do not pay attention to mental health education, which leads to the gradual marginalization of psychological education. "

　　As parents, what should we pay attention to in the process of raising children?

　　"Parents really need to reflect. They should not unilaterally ask their children to be excellent, but also always convey to their children an idea that parents love them no matter what their children are. If children encounter difficulties, they can always come to their parents for help; If the parents can’t solve it, let’s find a way to let the children feel that this home is a harbor. " Liu Yanru believes.

　　"Parents should have a positive growth mode of thinking. Parents should use more scientific parenting methods to give their children enough love, companionship and support, pay attention to their emotional changes in time, be good at discovering the advantages of their children, and encourage them to actively explore and try their own areas of interest. Healthy psychology is not overprotected, but tempered by exploration and trial. " Mao Min thinks.

Focus on experiencing the dual clutch test BYD Speed Sharp 1.5TID

　　[Evaluation] has been listed on August 21st, and it has become one of the most concerned models on car home website. The most striking thing is its brand-new "1.5T+ dual clutch" powertrain. This article focuses on its dynamic performance, especially the first performance of its own brand. As for the introduction of exterior interior and space, please refer to the static experience article for interested readers (click to enter).

　　This 1.5T model named BYD476ZQA has been seen in the world, with a maximum of 113kW (154hp) and a maximum of 240Nm, which completely surpasses the ordinary 2.0L naturally aspirated engine in terms of parameters. It is matched with the 6DT25 gearbox, with a maximum bearing torque of 240 Nm, which is just enough to match the engine.

　　Regarding the origin of the engine and gearbox, our colleagues in science and technology once made a detailed 1.5TID technical disclosure (click to enter). It is found that most of its structures are very close to the 1.4 engine and 7-speed gearbox. In fact, it is obtained by "reverse research and development" of the familiar Volkswagen 1.4 TSI+G.

　　BYD is not a simple imitation. It requires a lot of hardware. The key components are provided by internationally renowned suppliers, and the level of suppliers is no less than that of joint venture brands. In addition, the manufacturers have made some technological innovations, such as using aluminum alloy cylinder to reduce the weight, and the dual clutch module and electronic control unit (TCU) of the gearbox are also independently developed.

　　In daily driving, this power system works well most of the time. The 1.5T engine is relatively soft below 2000 rpm, and it starts to exert its strength obviously after more than 2500 rpm, and lasts until more than 5000 rpm. The shifting of gearbox between 1st gear and 2nd gear is a bit rough, and the shifting action of other gears is tight, and the setback is greatly reduced, which reflects the smoothness of dual clutch.

　　In the middle of the sudden acceleration, the response of the gearbox is slightly dull. In some cases, even if the accelerator is depressed halfway, it is unwilling to downshift, so it can only rely on the engine to fight alone and try to inject fuel. Fortunately, its low speed torque is enough and the sense of acceleration is barely acceptable.

　　If you want to get the best performance, you must step on the accelerator decisively, but you still don’t expect the gearbox to bring surprises. The downshift is always full of worries and lack of passion. Thankfully, the engine never lets people down. After the engine speed is raised, the whole car is finally refreshed, and the acceleration becomes carefree. When the speed exceeds 100 km/h, there is still stamina, which is comparable to the level of natural inhalation of most mainstream 2.4L

　　Like other dry dual clutches, Speedy 1.5TID is not very good at driving in congested road conditions. Frequent acceleration and braking make it hard to cope, accompanied by faint metal knocking, and the engine speed fluctuates slightly, which greatly reduces the ride comfort.

　　Speed Sharp adopts a steering device, the feedback is slightly biased, and the pointing accuracy in the middle small angle range is intentionally reduced to take care of comfort. The chassis is redeveloped, with no qualitative change in structure, and it is still a common torsion beam rear suspension. The overall feeling of the car body is improved compared with the previous products, and the feedback on road vibration is concise and neat, instead of emphasizing softness blindly, it maintains appropriate support.

　　In fierce driving, the body attitude feedback is timely, the suspension damping is linear, and the front direction is clear enough to be easy to control, which adds confidence to the driver. Another good thing is that the body stability control system is very delicate and always gently pulls the vehicle back from the out-of-control edge.
