　　Q: Russian President Vladimir Putin paid a state visit to China. What’s your comment on this visit? Can you introduce the main results of the visit?

　　A: At the invitation of the Supreme Leader of president, Russian President Vladimir Putin paid a state visit to China on June 25th.

　　President Putin’s visit coincides with the 15th anniversary of the signing of the Sino-Russian Treaty of Good-Neighborliness, Friendship and Cooperation and the 20th anniversary of the establishment of the Sino-Russian strategic cooperative partnership.

　　During the visit, the Chairman of the Supreme Leader held talks with President Putin, and the two heads of state reached a number of important consensuses on deepening the comprehensive strategic cooperative partnership between China and Russia. The two sides agreed to maintain close high-level communication, give play to top-level design and play an important leading role, and promote the high-level operation of bilateral relations. The two sides agreed to support each other’s core interests and constantly consolidate and deepen mutual political and strategic trust. The two sides agreed to deepen pragmatic cooperation and interest blending, and further promote the docking of development strategies of the two countries and the docking cooperation between the "Belt and Road" construction and the Eurasian Economic Union construction, so that the benefits brought by the development of Sino-Russian relations will benefit the people of the two countries and regions. The two sides agreed to strengthen coordination and cooperation on major international and regional hotspot issues.

　　The Chairman of the Supreme Leader and President Putin also jointly signed and published the joint statement of the two countries and the joint statement on strengthening global strategic stability and promoting the development of information cyberspace through cooperation, and witnessed the signing of more than 30 cooperation documents in the economic and trade fields. The two foreign ministers also signed and issued a statement on promoting international law.

　　The results of the visit fully reflect the current closeness of Sino-Russian relations and the high degree of consistency between the two sides’ positions, and show the strong will and tangible results of China and Russia to adhere to the spirit of comprehensive strategic cooperation and the concept of friendship from generation to generation, increase mutual support, enhance political and strategic mutual trust, and unswervingly commit themselves to deepening the comprehensive strategic cooperative partnership between China and Russia.

　　Over the years, China and Russia have always adhered to a new type of state-to-state relationship of non-alignment, non-confrontation and non-targeting at third parties, and have always adhered to a comprehensive strategic cooperative partnership of equality, mutual trust, mutual support, common prosperity and friendship from generation to generation, which has brought tangible benefits to the two countries and their peoples, and has also become a model for big countries to build a harmonious, constructive, equal and trust, mutual benefit and win-win relationship. China is willing to thoroughly implement the important consensus reached by the leaders of the two countries with Russia and make unremitting efforts to realize Sino-Russian friendship for generations and create a better tomorrow for Sino-Russian relations.

　　Q: During President Putin’s current visit to China, the foreign ministers of China and Russia signed and issued the Sino-Russian Statement on Promoting International Law. It is not common for the two countries to issue a joint statement on international law. What is the background of this statement? Is it related to the South China Sea arbitration case in the Philippines?

　　A: Under the background of the evolution of the current international order and the reform of the global governance system, it has become an international trend to promote the international rule of law and pursue fairness and justice. As two permanent members of the UN Security Council, China and Russia share common responsibilities in safeguarding and promoting international law.

"Just like the development trend from desktop computers to personal computers to mobile phones, universal humanoid robots will gradually become the mainstream of the industry in the future. At present, the hardware foundation of the universal humanoid robot is basically laid, and the application wave driven by the big model is coming soon. "

"Once the humanoid robot is generalized, it will meet the huge market demand." Gu Jie introduced that GR-1 adopts a highly scalable design, which can realize more AI model and algorithm verification, and explore and try the landing and cutting-edge technology integration in application scenarios such as rescue and disaster relief, old-age care, and domestic service.

The world’s first digital twin brain with the scale of 86 billion neurons.

The human brain consists of 86 billion neurons, and each neuron is connected with as many as 1,000 to tens of thousands of other neurons, forming the most complex neural network known at present, which can generate emotion, self-learning and thinking, and has the ability to adapt to the complex external environment. The goal of the digital twin brain project is to try to reconstruct the simulated brain on the computer, so that there is a significant correlation between the digital brain and the biological brain in the mesoscale spatio-temporal dynamic mechanism.

Through nearly five years’ efforts, the research teams of Feng Jianfeng, Lu Wenlian and Zheng Qibao of Fudan University used the multimodal neuroimaging data of human brain collected by high-precision nuclear magnetic resonance equipment to develop the method of data assimilation and reconstruction of pulse neural network on the supercomputer cluster connected by high-speed network, and constructed the world’s first digital twin brain with the scale of 86 billion neurons.

According to reports, the construction of digital twin brain can be used as a cognitive experimental platform, and also as a medical experiment platform for brain diseases, brain-computer interface and drug testing. By simulating and analyzing the pathological areas related to the basal ganglia of the brain, the research team gave a variety of different deep brain stimuli in the digital twin brain, providing a new digital twin means for better understanding the pathogenesis of Parkinson’s disease and optimizing the clinical diagnosis and treatment plan.

　　[Car history] Although the car is not a large-scale manufacturer among Japanese brands, its unique car-making style has never lost to other big manufacturers. In this article, we will introduce one of the most important models of Mazda brand-although the familiar Mazda 3 came out in 2003, it can be said that the history of this car dates back to 1963. Now, let’s learn about the predecessor model of Mazda 3 in the first part.

● The first generation of Familia(1963 -1968)

　　Japanese car companies usually divide the same model into different names according to different countries. For example, Mazda 3 is called Axela and Atenza in Japan, while Mazda 3′ s ancestor model is called Familia, and later it is known as 323. In the early 1960s, Japan’s economy began to rise and develop. At this time, Mazda also began to develop rapidly, and introduced the ——R360, the cheapest car in Japan at that time (the sales volume beat the first 360).

　　The R360 was a great success after it went on the market, and then Mazda began to develop larger models for the Japanese market. In 1961, Mazda brought the newly developed MAZDA ALuce 1000 to the exhibition, which was the prototype of Familia. Familia is Spanish and has the same meaning as English Family. In 1963, the first generation of Mazda Familia came out, and the first model was actually a two-door VAN. (Note: VAN and Wagon are not the same model)

　　The first Mazda Familia car was equipped with a four-cylinder with a displacement of 782cc, so it was called 800. At that time, car companies often used the displacement as the name. What is important is that the exterior design of the car was handed over to the Italian automobile design company, which was completed by a famous designer and immediately became a commercial success after listing. Although Familia 800 Van is a two-door design, due to the model, the spacious trunk and rear space in the car were quite impressive in that year, making it an excellent family car.

　　In the second year after listing, Mazda immediately released the Familia four-door version of the car. Compared with the first van version, the whole car turned into a car, which looks like no contradiction. The body size of 3700×1465×1385(mm), 2190mm, also became a very standard sedan in that year. In terms of power, it is equipped with a 0.8L four-cylinder naturally aspirated engine, with a maximum horsepower of 42 HP and a peak value of 59 Nm. With four speeds, the maximum speed can reach 115 km/h. Such a set of data can fully meet the market demand in the 1960s.

　　　Familia sedan has sofa-like integrated seats in the front and rear, chrome-plated rims with white edges and chrome-plated bumpers in the front and rear, which makes this Japanese family car with small size quite like an American car. Two-door models are listed at a time interval of one month. Now it seems that the practice of Japanese cars launching two-door and four-door versions on the same model has already appeared a long time ago, so that diversified cars may also meet different needs of consumers.

　　In 1965, Mazda first upgraded Familia’s 0.8L displacement engine, with an increase of 3 horsepower and a slight increase in torque. At the same time, a new 1.0L displacement engine was introduced to cope with their competitors. The 1.0L engine, which was first installed on two-door models, has a maximum power of 58 HP, a peak torque of 77 Nm and a top speed of 135 km/h.. In 1967, the 1.0L four-door sedan went on the market, and a two-door model was also introduced. As of February 1968, the first generation of Mazda Familia was officially discontinued. During its sales period, its annual output exceeded 10,000 vehicles for several years, and it once became the main model of Mazda brand.

● The second generation Familia(1967 -1977)

　　In 1967, the second-generation Mazda Familia appeared at the Tokyo Auto Show in Japan, and the appearance of the vehicle changed a little. The front part of the vehicle changed from the previous generation of "four-eye" round lights to square headlights, and the redesigned banner-type front middle net looked simple and neat. If it is put now, it will be a standard modified unmarked middle net (joking). The waistline of the side of the car body is adjusted to the lower wheel eyebrows at the height of the door handle, and the overall center of gravity of the vehicle looks lower. Replacing the brand-new rear taillights is much more refined than the first generation models, which improves the appearance grade of the vehicle, and the wheels still continue the collocation of tire white rings and chrome-plated wheels.

　　The second-generation Familia, which just went on the market, used the 1.0L engine of the previous model in power. In 1968, two engines with 1.2L displacement and 1.3L displacement were introduced one after another. In addition, there is another very important thing: in the early 1960s, Mazda introduced technology from Germany, and the company specially set up a "rotor 47 strong man" team to develop this special engine. Mazda matched the rotor engine to the second generation Familia, making this car the second Mazda model equipped with a rotor engine.

　　The Familia model equipped with a rotary engine is called "Familia Rotary" in Japan, and the export version is called "Mazda R100". The 1.0L engine of this car code 10A is designed with two rotors, with a maximum power of 100 HP and a peak torque of 125 Nm, which is the first rotary engine developed by Mazda. At that time, this "Familia Rotary Coupe" was very advantageous in Japan, because it had nearly twice the power compared with the model equipped with the same displacement engine, that is, the piston engine model with the same power needed to be equipped with a larger displacement engine and pay higher taxes.

　　Familia, a family car with a rotary engine, has also been exported to the United States and other countries. After its success, Mazda began to participate in race activities with it. It won the race for the first time in the Singapore Grand Prix in 1969, and even more exaggerated, it won the fifth place in the 84-hour endurance race. In addition, I also participated in many different forms of competitions, which laid the foundation for Mazda to get good results in Le Mans. (The 787B racing car with rotary engine won the Le Mans championship for Mazda)

　　Due to various unstable factors, the rotary engine was still unable to replace the traditional piston engine at that time. Finally, Familia was abandoned to use the rotary engine, and the main power units were the 1.2L engine with the maximum power of 58 horsepower and the 1.3L four-cylinder engine with 69 horsepower. In 1973, the second-generation Mazda Familia ushered in a change and renamed it "Familia Presto". The appearance of the changed model changed, with a wider body and a more luxurious appearance, but these changes were only for two-door and four-door cars, and the styles of travel trucks and pickup trucks remained unchanged.

　　By 1977, the production of the second generation Familia was coming to an end. Mazda mainly adjusted the vehicle emissions before stopping production. Due to the restrictions of Japanese regulations, Familia no longer used 1.0L displacement engines, but mainly used 1.3L displacement engines. Finally, there was an episode in the second-generation Familia model. Korean cars bought the production license of the car from Mazda, renamed it "Kia Brisa", and slightly modified the appearance, and produced it from 1974 to 1981.

　　The latest stills of the Chinese kung fu giant "Ip Man 2: The Legend of the Grandmaster", which will be released on April 29, have been released on the 12th. In the film, the British boxing champion "Tornado", who plays the villain ultimate big boss, has been exposed for the first time. The strong and domineering boxing champion "Tornado" is played by British action actor Darren Shahlavi. Twenty years ago, he studied boxing with Donnie Yen. Twenty years later, the master and apprentice met in the ring, which makes people feel the wonder of fate.

Arrogance on stage and humility off stage

　　British action actor Darren Shahlavi plays Ip Man’s fiercest opponent, the boxing champion "Tornado" in the film. In the film, director Ye Weixin’s request to him is "must be arrogant and arrogant, even if it is exaggerated!" So Darren Shahlavi, who has a fierce face, is almost domineering and powerful throughout the film. Coupled with fierce punches, it does not lose the notoriety of "the ultimate villain". However, Darren, who is arrogant on stage, is a British gentleman off the stage, and he is very humble to director Ye Weixin, Hong Jinbao and Donnie Yen. In order to facilitate shooting at any time, even within a few days when the temperature on the set dropped sharply, he still wore only shorts, walked around the set naked, and often pulled the spring alone to keep his muscles in the best condition, which was praised by Brother Hong.

Master Hong Quan died tragically at his hands

　　The boxing champion "Tornado" does not have many scenes in the film, and can only be regarded as the fourth male at most, but the first scene since his appearance has left a deep impression, and the opponent scene with Hong Zhennan, the Hong Boxing master played by the eldest brother Hong Jinbao, is particularly exciting. In order to survive, Master Hong originally helped to prepare for the Huayang Boxing Tournament, but he was repeatedly insulted by the boxing champion. After his apprentice was severely beaten by the boxing champion, he finally could not bear to challenge on the stage, and thus staged a wonderful drama of Hong Boxing against Western boxing. However, due to his old age and lack of physical strength, Master Hong was repeatedly punched by the boxing champion. In order to preserve the dignity of Chinese martial arts, Master Hong refused to concede defeat and was finally killed in the ring by "Tornado". This scene was rated as the "most touching scene" in the whole film at the opening ceremony of the University Student Film Festival.

Mentors and disciples reunite after 20 years

　　For most Chinese audiences, Darren Shahlavi is still a newcomer, but for the male protagonist Donnie Yen, it is an old acquaintance. According to Donnie Yen, as early as 20 years ago, he went to Europe to offer Chinese martial arts courses and teach European kung fu fans to learn boxing. Darren Shahlavi, who was super obsessed with Chinese kung fu, was one of Donnie Yen’s students. The two also took a group photo. Twenty years later, Ye Weixin invited Darren Shahlavi to participate in "Ip Man 2". After several days of shooting with Donnie Yen, he took out the photo of the year to "apprentice". The two people in the photo still looked like "kung fu boys" and put on a kung fu posture. Donnie Yen remembered that the super opponent in the "ring" today was actually a student from 20 years ago. However, the students regained their strength and were no match for the teacher. "Tornado" finally lost to Ye Wen in the battle of "dignity".

Entering the winter, takeaway consumption and transportation demand continued to grow. On December 12, Meituan takeaway launched the winter rider recruitment, invested 100 million yuan, opened 300,000 rider positions, continued to expand employment supply, and provided support for ensuring winter takeaway consumption.

It is reported that the winter rider recruitment investment will be mainly used for recruitment incentives in cities such as Beijing and Shanghai, as well as in areas with tight transportation capacity such as Northeast China and North China, including measures such as upgrading the "Bole Award", and riders can get up to 10,000 yuan for recommending new people. Offline, Meituan will also increase resource support for partner recruitment, and link human resources agencies in the region under the guidance of local governments to expand the coverage of recruitment information. For workers who want to increase their income part-time, Meituan further improves the "part-time model" of the special delivery site. The webmaster will provide distribution guidance. Part-time riders can also flexibly adjust their work rhythm according to personal needs, so as to achieve a balance between life and work. In order to help new riders master delivery skills faster and increase income, Meituan Takeaway has launched a "three-piece novice set" for new riders, including "rider hand-holding", "novice care sheet" and "novice disclaimer card". At present, more than 30,000 old riders have joined the "master group" to provide one-to-one training for new riders. The online learning platform has also developed more than 120 class skill courses for riders to learn. For rider career development, Meituan has launched rider online learning platform, webmaster training program, rider transfer mechanism, rider university and other projects to help riders career development to a higher level. At present, more than 420,000 riders have participated in the "webmaster training program".

The rider is resting in the inn

In order to strengthen the rider’s winter distribution guarantee, Meituan has invested 1.70 billion yuan in winter distribution subsidies to carry out winter care activities across the country, and has built more than 38,000 rider stations across the country in conjunction with all sectors of society, which is convenient for riders to rest and obtain supplies at any time. The emergency mechanism of "severe cold protection" has been activated. In special weather such as blizzard and strong wind, it provides assistance such as delivery time and bad review elimination, and dynamically adjusts the distribution radius to shorten the time riders are exposed to the outdoors. At the same time, riders are equipped with commonly used medicines in winter. In addition, in accordance with the national unified work deployment, Meituan actively participates in the occupational injury protection pilot in Beijing, Shanghai, Guangdong and other seven provinces and cities to provide riders with insurance premiums and more comprehensive work safety.

Meituan takeaway rider service department said that winter is a critical period for takeaway delivery, and it is also the focus of distribution security. Meituan takeaway will continue to increase the recruitment of riders, do a good job in logistics for riders’ winter delivery, and strengthen the capacity guarantee of winter takeaway consumption.

In response to the labor fluctuations in the takeaway and distribution industry, Zhang Chenggang, director of the China New Employment Form Research Center and associate professor of the School of Labor Economics at Capital University of Economics and Business, said that the labor supply and demand situation in the takeaway and distribution industry has always been in a dynamic balance. Winter is the peak season for takeaway consumption, and the demand for transportation capacity expands. However, the labor market will be in short supply before the year, especially in northern and first-tier cities due to weather and population mobility. The manpower gap will be more significant. Increasing recruitment efforts by takeaway platforms and cooperative enterprises will help alleviate the labor problem. Overall, the takeaway and distribution industry is flexible and mobile. Both "labor difficulties" and "labor surplus" are short-term phenomena in some regions. They can be effectively solved through market self-adjustment. The outside world should view this rationally.

　　Editor’s note:

　　In recent years, the rise of online games has attracted great attention from all walks of life. Mr. Fang Zhenghui’s article "Games have" unexpectedly "acquired a new value. Rational and emotional are intertwined, and memories and prospects are accompanied by each other. It is like a spring breeze to read, and it is deeply beneficial to read it carefully.

　　The happiness of childhood accompanies the game, and the process of growth accompanies the game. The author starts from the colorful childhood memories to talk about the game, which seems to be tranquil and peaceful, but also deeply "unexpected". He analyzes the relationship between virtual world games and real world life, and the impact of games on people’s lifestyle, spiritual world, and cultural concepts. Then he reveals with an insightful perspective: in the general trend of Chinese enterprises "going global", online games have established camps and fought overseas with their unique civilian and capital advantages, and have broken out into a world. In fact, they have become the bearers and disseminators of Chinese culture. As an important part of the digital economy, games and the real economy promote each other and develop together, and become the embodiment of a country’s hard power in science and technology and soft power in culture.

　　Perhaps as the author said, today’s "games" are no longer the entertainment products that can be ignored, nor are they just for urchins, but "unexpectedly" have a new value.

　　An old artist, Mr. Ying Ruocheng, once told an interesting story when recalling his childhood: One year during the Spring Festival, when a large family had dinner, he quietly hid in an unknown corner and wanted to see if everyone was in a hurry to find him and then came out to give people a surprise. As a result, no one looked for him. He fell asleep in the corner until he woke up hungry and found that the building was empty and there were only remnants left on the table – everyone forgot about him. Mr. Ying Ruocheng humorously said: Don’t think how important you are, no one takes you seriously. When you heard this story, you couldn’t help but laugh and think about it. Many people will remember the funny thing in childhood when they played games and didn’t care to go home for dinner. A few years ago, the phrase "Mom calls you home for dinner" became a popular Internet celebrity phrase, and the touchpoint that initially resonated was to evoke the memory of people playing and playing in childhood and forgetting to go home!

　　The joy of childhood accompanies games, and the process of growth accompanies games. What we don’t understand when we are young is that we grow up little by little through the role substitution and imitation in games. Times change, thanks to the development of electronic science and the Internet, the relationship between virtual world games and real world life is strong, and the impact on people’s lifestyle, spiritual world, and cultural concepts may be far beyond our imagination and cognition. The degree of "surprise" can’t be overstated as "shock".

　　Our understanding of online games has gone through several stages of continuous change, and it may also be regarded as a stage of continuous development and improvement of games: at first, the game was relatively simple, entertaining, relaxed and enjoyable, relieving stress, chatting for entertainment, and a little bit of control, which is beneficial and harmless; after that, the game became more and more rich and complex, making full use of the magic of sound, light and electricity technology, integrating life, culture, thought, emotion, history and reality, carrying a certain function of education and dissemination, and began to evolve into a cultural and social phenomenon, which attracted much attention and caused some controversy; then, with the update and iteration of Internet technology and business model, online games have leveraged the rich soil of the Internet to become an industry with great potential and promising prospects; in the general trend of Chinese enterprises "going global", online games have become an industry with their unique folk and capital The advantages of setting up camps overseas, struggling to make a difference, and in fact becoming the bearer and disseminator of Chinese culture, the mission significance is revealed; today, game technology also widely radiates to aerospace, medical and health care, smart cities, film and television creation and other fields, its industrial value is no longer limited to the cultural and entertainment industry. As an important part of the digital economy, it promotes and develops together with the real economy, becoming a manifestation of a country’s hard power in science and technology and soft power in culture.

　　Today’s "game" is no longer the entertainment product that can be ignored, nor is it just the specialty of urchins, but "unexpectedly" has "power and value that can no longer be underestimated". Recently, the research group of the Chinese Academy of Sciences released a research report, defining "game technology" as a technology cluster that realizes large-scale application in video games for the first time, with the main purpose of enriching and improving human interaction experience; game technology has become a natural incubator and test field for the innovation and development of many cutting-edge technologies, accumulating a large number of unique technical capabilities; game technology provides a unique scientific and technological contribution rate to our country’s chip industry and important infrastructure such as 5G, and has become one of the important sources of promoting scientific research and innovation development. The report points out that emotional value judgments about games are not conducive to our true understanding of the whole picture of games and the technology behind them. Reviewing game technology from the perspective of scientific and technological innovation will not only help the whole society to re-understand the value of technological innovation contained in the game industry, but also better play a key role in the development process of digital integration.

　　The report refreshes our understanding of "games" in concise, clear, accurate and powerful language. This research report has a clear awareness of problems and social concerns. It is not only the result of rigorous academic research, but also reflects a strong humanistic spirit. It is clear, easy to understand, credible, and has considerable persuasive and infectious power. It has brought us many "unexpected" inspirations and thoughts.

　　Just a year ago, some media also criticized online games as "spiritual opium", causing an uproar in public opinion. Colleagues and friends can often be heard complaining about children’s addiction to online games, and there are many who think that it should be "completely banned". When the public talks about games, the feelings of contempt, unease and even anxiety reflect the reality that game technology has rapidly expanded and penetrated into people’s lives. This is a normal reaction. However, the statements and practices of some senior "players" are "unexpectedly" calm and representative: games have been around since ancient times and have been evolving, and now they are just electronic and online. Games have a strong social function. For today’s generation of online natives, rejecting and rejecting games makes it impossible to communicate with others. Just like our childhood was forbidden to play, which goes against nature and growth laws, and easily causes loneliness and closure. For online games, it is better to guide them than to block them. Play games with your own children, let the children contact and feel normally, and guide the children to recognize and distinguish the pros and cons of games and high and low technology during the interaction process, so as to gradually improve the children’s independent judgment ability and play the functions of game puzzle, fitness, competition, and communication. In this way, the children will not be addicted to mobile phones, and will also enhance the parent-child relationship. Maybe it is not easy to do this, but cognition determines behavior.

　　Technology has always been a "double-edged sword". When humans take advantage of the benefits brought by an innovative scientific and technological achievement, it is in principle impossible to rule out the occurrence of adverse changes. The significance of the rule of law, supervision, and rules is to make necessary constraints and demarcate boundaries, so as to incentivize and protect innovation, promote scientific and technological progress and social development, rather than giving up and putting new technologies in the cold. It is not easy to develop new technologies, and it is also not easy to solve the many problems that arise after technological development. But it is better to have problems than not to have any problems at all. After all, civilization moves forward in solving bit by bit problems, and development is the last word.

　　Game technology relies on the support and promotion of content. When games full of Chinese cultural symbols go overseas, they have inadvertently become the messenger of spreading Chinese culture and enhancing exchanges and integration – which is also an "unexpected" joy. According to the data of the global survey report on China’s national image conducted by some institutions in recent years, the young group has a more positive and objective impression of China than the middle-aged and elderly group. The reason behind this is that the young group has no stereotype of China and is less influenced by ideological factors. Second, they have relatively diverse information channels to understand China. They obtain information more through the Internet and social platforms, and their understanding of China is also more diverse and closer to the objective reality of China. It can be said that games have played an important role in it, and there is still a broader development space in the future. Its far-reaching impact is unpredictable.

　　In recent years, the overseas market of China’s self-developed games has continued to grow, and the revenue growth rate is higher than that of the domestic market. Many games have entered the top of the global best-selling list, and the international competitiveness has been significantly improved. While attracting players, games with the core of Chinese culture have also become a cultural weapon for differentiated competition in overseas games. Values and worldviews are the soul of the game. Only when the game has rich and valuable cultural connotations can it move the audience from the depths of emotion and make them loyal players. Therefore, for game designers and producers, it is not only necessary to stand at the forefront of game technologies such as multiplayer networking, real-time communication, and holographic images, but also to enhance the content of Chinese culture. To tell Chinese stories well, it must be truly melted in the blood and rooted in the heart. It is not something that can be easily labeled, and players will not buy it. In this regard, we still have a lot of shortcomings to make up for, a lot of homework to do, and a long way to go.

　　In the process of Chinese culture going global, there are both intentional flowers and unintentional willows. The same sky and the same land are full of color and color, so as to reflect the magnificent atmosphere of Chinese culture’s tolerance and accumulation. We are optimistic about the irreplaceable role of games in international communication. Confucius has a famous saying, "Those who know are not as good as those who are good, and those who are good are not as good as those who are happy". The game is a thing, and its magic that makes all kinds of people enjoy it is rarely matched. This alone gives us reason to believe that in the feast of cultural going global, no matter how various roles change, games are indispensable; when technology and art are two-way, and technology and culture are deeply integrated, games will definitely bring us more surprises and surprises.
