Looking at Huawei’s three excellent qualities from the three highlights of the new M7.

The new M7 was a hit, and it won an order for 15,000 vehicles within 24 hours after the launch. You know, after many slaps, most car companies will not announce the order results within 24 hours or 72 hours after the press conference. Dare to let go of the fear of being beaten in the face in the future and announce the order results, which reflects the great confidence of the Helix team in this product. However, considering the conversion rate of orders, the order data is actually of little reference significance. What really makes sense is the first weekend after the press conference. A big order refers to an order that actually pays a deposit of more than 10 thousand yuan and can basically be converted into actual delivery. At the new product launch conference in autumn, Yu Chengdong revealed that the new M7 has been on the market for less than two weeks, and it will definitely exceed 20,000 units. The bright figures show that the new M7 will definitely become an explosion.

Some people think that the rapid explosion of the new model M7 is influenced by the light of Mate60 and Huawei, especially after the breakthrough in the production of 7-nanometer chips and the launch of Mate 60, Huawei’s voice volume is in full swing, and the new model M7 has achieved such good sales. This is only half right. To tell the truth, the new M7 is indeed exposed to the light of Mate 60 to a certain extent. After all, the cars in the world are sold in Huawei’s stores, and the huge number of stores brought by Mate 60 will inevitably increase the exposure of the new M7. But it’s as normal as your brothers and sisters in your work and life. If the hat of the great hero who broke out in the world of inquiry M7 is buckled on Mate 60, it is unfair and objective to the team of inquiry. You should know that mud can’t help the wall. If the new model of inquiry M7 itself doesn’t give strength, Mate 60 will shine again and will not shine on it.

Therefore, we still have to go back to the product itself to find the answer.

500 million rejuvenation short board becomes bright spot

In the marketing of the new model M7, Huawei and Sailis team found three highlights to promote: safety, comfort and intelligence.

When I first saw the propaganda copy, the author smiled knowingly. Because, if you still have the impression, the author has analyzed the reasons for the misfire of the old M7. First, the test conducted by China Insurance Research Institute made consumers put a big question mark on the safety of the M7. Second, the wheelbase is too short to arrange three rows of space, and the comfort experience is greatly reduced; Third, despite Huawei’s brand aura, in terms of intelligence, the old M7 only has the icing on the cake of the HarmonyOS cockpit, but there is no high-end intelligent driving that high-end consumers are increasingly concerned about. In other words, the three highlights of the new M7 marketing-safety, comfort and intelligence-all have obvious shortcomings in the old M7 marketing.

Let’s start with safety. At the launch conference of almost every new car of BYD, the golden sentence that Wang Chuanfu, the head of BYD, said at the blade battery launch conference was later widely circulated in the industry-safety is the greatest luxury of new energy vehicles. In the new species of new energy vehicles, safety is mainly reflected in two aspects-body safety and battery safety.

For a rigid object that weighs two or three tons and can move at high speed, safety is a political correctness. From the sales volume of Volvo, safety is not the biggest persuasion factor when people buy cars, but from the peak drop of M7 sales volume of the old model, we can find that safety is definitely one of the biggest persuasion factors when people buy cars. After the resumption of trading, there are many reasons for the sales collapse of the old model M7. For example, the ideal L8 is really more amazing. For example, the test of China Insurance Research Institute directly destroyed the momentum of the M7. Therefore, the M7 500 million rejuvenation has put a lot of energy into the upgrading of body strength.

Image source: Huawei

The strength of the car body is closely related to the proportion of high-strength steel and the price of the car. For example, the high-strength steel of BYD’s Qin Plus DMI, which "subverts fuel, Qin rules the world", accounts for 52%, the high-strength steel of Audi A series accounts for 62%, the high-strength steel of LI accounts for more than 75%, and the high-strength steel and aluminum alloy of the new model M7 account for 80.6%.

As for battery safety, Huawei has taken advantage of its own cloud-side collaborative algorithm. Through the combination of local BMS and cloud BMS, it has prevented unburned, creating a good result of selling hundreds of thousands of cars in the world.

In terms of comfort, the author always thinks that changing three rows into two rows and six seats into five seats is a stroke of genius. It is indeed a little stretched to make three rows with a wheelbase of 2.8 meters, and it will inadvertently make the third row of passengers inferior. Since it can’t be arranged, it is simply changed to two rows, so that each seat can be arranged properly. As for other comfort upgrades, it is somewhat eclipsed in front of the 6-seat flying fairy.

The biggest improvement in intelligence is, of course, the introduction of Huawei ADS2.0, a high-order assisted driving function that can be used on the structured roads of all cities in China at the end of the year.

Image source: Huawei

After a year’s market education and the efforts of major car companies such as Huawei and Tucki, consumers of models with a price range of more than 250,000 have gradually accepted and recognized the value of advanced assisted driving. In the high-speed scene, more and more consumers have liberated their hands and feet through high-speed NOA, and gained a more relaxed and comfortable driving experience. In this year’s market environment, if a mid-to-high-end vehicle does not have the ability or potential to assist driving in urban areas, it is basically difficult to achieve good sales performance. We can accurately capture this from the bleak sales of BYD Tengshi N7. It is also based on this judgment that the new model M7 decisively abandoned the third-party intelligent driving solution of Wen Yuan Zhixing and directly launched the "far ahead" Huawei ADS. It is precisely because at this stage, Huawei (and Tucki) have achieved a real lead in the field of autonomous driving, so this short board that Huawei has filled in on the new M7 has become its biggest highlight.

Three qualities of Huawei team

After the above analysis, we can find that the old model M7 has shortcomings that can’t be ignored in three aspects: safety, comfort and intelligence, while the new model M7 applies force accurately and carries out targeted transformation and upgrading. Next, we turn from the product level to the organization level, and realize the excellent quality of Huawei BU team by asking the M7 for the accurate change.

The first good quality is seeking truth from facts, dare to face problems directly, do not evade, do not evade, and get up from where you fell last year. The three shortcomings that users spit out have become the three highlights of the product.

The second quality is pragmatism, accepting the fact that the post-80s generation has become the mainstream consumer group in the mid-to-high-end automobile market, and carrying out targeted transformation and upgrading to meet the mainstream needs of this group. Compared with the driving experience, the post-80s generation, which has become a nanny or treasure mother, pays more attention to the elderly’s riding experience and children’s entertainment needs. The former needs a large space, which requires a spatial layout, and the third row needs to be changed into two rows. The latter needs color TV or flat panel. MagLink has achieved the front row control and linkage requirements while ensuring the rear row entertainment experience.

The third excellent quality is flexible and decisive, conforming to the reality of market downturn and industry involution. Based on the current situation that the volume and sales volume of the industry have gradually declined in the past six months, we will decisively reduce the price and increase the distribution, and bring the dead old products back to life with sincere prices. Compared with the old model, the new model is 60,000 yuan cheaper, and 70,000 yuan cheaper than the ideal L7, the main competing model. Even if we have to reduce the suspension of 20,000 yuan on the basis of 70,000 yuan, it is also 50,000 yuan cheaper.

Write it at the end

No car company has invested hundreds of millions of dollars and a lot of manpower and material resources to make a car, and does not want to achieve a good sales result. If it doesn’t meet the enterprise’s hope in the terminal market, there must be some problems in some aspects. What should we do to face the problems? What kind of answer should car companies give? At this time, it is a special test whether the car companies can make an effective resumption, accurately judge the problem and give targeted solutions.

After comparing the new and old questionnaire M7, we can realize that Huawei and Mercedes team are practical, pragmatic, flexible and decisive from its three highlights. This car is far ahead of intelligent driving, with a comfortable space of five seats, and the price has hit 250,000. Why not become a super explosion?

Language is a sword! "Knife’s Tip" Exposes a New Preview: Hidden Dao in Zhang Yi Dialect


1905 movie network news Recently, the spy war movie released a brand-new trailer, playing the special agent Jin Shenshui. In the extreme environment where many forces are intertwined and everyone has their own ulterior motives, a few words seem to be light, but in fact, every sentence is extremely deliberate, killing the enemy in an instant, which can be described as "hiding the knife in the words and killing the invisible".


Based on the novel of the same name, Knife Point is directed by Zhang Yi, starring,,,, starring, and will be released on November 24th.


The story background of Knife’s Blade focuses on Nanjing, which was devastated in 1940. Director Gao Qunshu once said that in this cruel environment, "everyone is thinking about how to survive, whether it is our side, the military system or Wang Fei". Jin Shenshui (Zhang Yi), a special agent with multiple identities, lives among the forces of the Japanese military, the puppet government and the military junta all day long, not only carefully hiding his true identity, but also quietly alienating the enemy and making excuses to kill people.


In the newly released trailer, everyone in the life-and-death training ground is on thin ice, and Jin Shenshui uses the characteristics of everyone’s own ulterior motives to exert a "deviant plan" in an extremely ingenious way. In the tense situation, it turns a few words that seem to be light and light into a sword that stabs the enemy.


As director Gao Qunshu said, the most thrilling thing in spy war is often not reflected in the real fight, but "hiding a knife in words, killing people invisibly". "Everyone’s words have a deep killing trick, and it seems that if you say a few words casually, you can kill people." Jin Shenshui, a special agent who witnessed his family being killed by the Japanese invaders and suffered extreme pain, turned himself into a "motionless blade", not only to get rid of the enemies around him, but also to protect the safety of his compatriots.


Like him, Lin Yingying, who hates her country’s enemy, also shows a fighting capacity different from ordinary people under the image of calmness and gentleness. Gao Qunshu explained that the strength given to her by the organization behind her "made her support this mentality of being bold and cautious, killing people without tricks and killing people invisibly". Whether it is Jin Shenshui or Lin Yingying, you must have extraordinary courage and strategy to walk on the tip of the knife. "Either you beat your opponent to live, or you sacrifice yourself to help your comrades live."


How many movies do you know that have a full dialogue but no slots?

1905 movie network news At present, many movies at home and abroad rely on grand scenes, exquisite special effects, thrilling blasting and so on to win the audience’s attention, but few movies really rely on actors’ acting skills and stories themselves to win both box office and word of mouth. Today, Xiaobian will recommend several movies that you can never get tired of watching.

First, the game of wise men who decide life and death:

This is a film adapted from real historical events in Britain. The story tells the most famous conversation in British history. The two sides of the conversation were ian Paisley, the leader of democratic unionist party in Northern Ireland, and martin mcguinness, a politician of the New Finland Movement. The conversation took place in Britain during the turbulent period, when the British people were under the threat of death every day, and the meeting between the two politicians decided whether thousands of people could spend a peaceful period safely.

This one-and-a-half-hour-long film, from the very beginning, explains the reasons for the meeting between the two men, to how the political team behind it arranged the space for them to be alone behind the scenes, and finally, how the two men reached an agreement in mutual sarcasm and disputes, without delay.

One of the highlights of the film is that the scene of their conversation is placed in the back seat of a commercial vehicle. During the short hour of escorting ian Paisley to the airport, the political team needs to race against time to create opportunities for peace talks between the two, including arranging special drivers and setting up roadblocks to extend the time, because it is related to the lives of tens of millions of people and the future of Britain.

The second wonderful thing is the dialogue between the two people, which sounds like sarcasm, but in fact they are playing games with each other. Both of them stick to their political opinions and have no intention of giving in. But in the end, the two sides finally compromise for peace, but this compromise is not a concession of political opinions. Just as at the end of the film, Ian made Martin apologize for the explosion in Britain as a condition for peace, but Martin refused, and this refusal touched Ian and made him realize that their insistence on politics was actually the same.

The lines of the whole movie are particularly logical, and it is difficult for people to imagine how the real scene developed at that time, but it is precisely because of the images that this historic moment can be highly restored, which is the unique charm of the movie.

 

Second, the intrigue for the truth:


This suspense masterpiece from Spain was released in China this year, and it was once a double harvest at the box office. The story is about a mother who dressed as a lawyer to investigate her son’s death, and finally the truth came out.

In the film, the hero and heroine are in a closed room, trying to find each other’s loopholes with language. The hostess and mother use superb conversation skills to win the trust of the man first, and then slowly let the man tell the truth himself, while the suspect of the other man fabricates one story after another to try to cover up the facts, but in the end, she can’t resist the psychological defense line and is broken by the woman. After he tells the truth, the woman leaves the room. He didn’t realize that the lawyer who just walked into the room was not a real lawyer. In the last shot, he looked out of the window and looked at a pair of middle-aged men and women who were watching him in the opposite window. The woman took off her costume and the man’s face gradually emerged with a look of surprise.

This masterpiece, which scored 8.7 on Douban, is different from other suspense films. It takes conversation as the main line, and the two people perform different versions of the story in the intrigue between words. But in the end, the audience can only distinguish the truth by virtue of their dialogue, which can be described as an extraordinary brain-burning film.

 

Three, spying on the secret tit for tat:


This is a realistic work that reflects the fragile emotional relationship between people at present. The story mainly tells a series of unexpected stories about seven good friends at a dinner because of a game.

The setting of seven people in the film is two couples, a pair of lovers and a man who is afraid to bring his partner to meet his friends. At the dinner table, the hostess, who is a psychologist, suggested that everyone play a game. The rule of the game is that everyone should put their mobile phones on the dinner table and share any phone calls or text messages all night. Imagine that in this information-oriented era, mobile phones have almost become the most special private space for everyone. As the movie said, it is like a Pandora’s box. Once opened, I don’t know what will happen. It is in this game that everyone’s unknown secrets begin to surface. There is no loyalty between husband and wife, no trust between friends, and everyone tries to defend with pale and powerless language, but all broken relationships are like broken mirrors, which can not be healed by just a few words.

This high-scoring movie, which also scored 8.6 on Douban, is almost a dialogue. Everyone connects lies with the truth in series. Only by watching this movie seriously can the audience sort out this complicated relationship between people. At the end of the movie, they will inevitably sigh that in the current information age, although the relationship between people has been expanded, it is so fragile, and everyone needs a Pandora’s Box of their own to load things that they don’t want to be known.

 

Fourth, the strange story of staggered space:


This is a complete brain-burning film. There are nearly ten protagonists in the same room, and the relationship between them depends on the dialogue between the characters. In the first half of the film, it will bring people a sense of seeing things in a fog, but it will make people feel more and more jittery later, especially when everyone talks about the strange phenomenon when the comet comes. The ensuing power outage causes everyone to leave the house and meet the same themselves in the street for help. This series.

It is reported that when the film was filmed, the director only provided information about the relationship between the actors and characters, and what the lines should say and what they need to do all depended on the improvisation of the actors, which shows how amazing the performance of this group of old actors is in front of the camera. Compared with the previous two films, this part adds sci-fi elements to it, and leads the audience into a world with wide brain holes through similar stories of the same characters in different timelines and different spaces.

Conference | The First International Workshop on Frontier Research of "Chinese Etiquette Debate and Nakanishi Rei Studies"

Nowadays, "the dispute of Chinese etiquette" has become a technical term. Whether it refers to the dispute between the East and the West in a narrow sense (1583-1742) or a series of historical facts that have almost run through the whole communication between China and the West since the Ming and Qing Dynasties in a broad sense, the "Chinese etiquette dispute" can be called a major event in the long history of cultural exchanges between China and the West. It is of great significance to the comparison, dialogue and communication between different civilizations in the world today, and its importance is beyond doubt.

On May 11, 2019, the first international workshop on the frontier research of "Chinese Etiquette Debate and Nakanishi Rei Studies" was held in the Convention Center of Shanghai Normal University. With the innovative way of "interdisciplinary dialogue and parallel research", the workshop gathered more than 30 experts and scholars at home and abroad to explore and expand the way of communication and dialogue between China and foreign countries.

The first international workshop on the frontier research of "China’s Etiquette Debate and Nakanishi Rei Studies" brought together more than 30 domestic and foreign experts and scholars from Fudan University, Wuhan University, Central South University, Institute of World Religions of China Academy of Social Sciences, South China Normal University, Anhui University of Science and Technology, Vassar University in the United States and other Chinese and foreign universities and research institutes. The workshop was jointly sponsored by Shanghai Comparative Literature Research Association, Li Xu Wenming Dialogue Research Center of Fudan University and China Language and Literature Innovation Team of Shanghai Normal University, and was specifically undertaken by the editorial department of Comparative Literature and World Literature, the national key discipline of Shanghai Normal University.

The opening ceremony of the workshop was presided over by Associate Professor Ji Jianxun, majoring in comparative literature and world literature in Shanghai Normal University.

Professor Cha Tsinghua, Dean of School of Humanities and Communication, Shanghai Normal University, and Professor Liu Yunhua, Head of Comparative Literature and World Literature, delivered speeches respectively. Dean Cha first warmly welcomed many experts and scholars from home and abroad, and then introduced the characteristics of Shanghai Normal University’s comparative literature and world literature from three aspects: continuity of development, interdisciplinary and cross-cultural education, and the fine tradition of paying equal attention to academic research and personnel training, and put forward valuable suggestions for the future of disciplines, which should not only seize opportunities, but also continue to improve modestly and cautiously. Professor Liu Yunhua further pointed out that the purpose of the discipline is to create a relaxed, pleasant and truth-exploring academic environment, and placed deep expectations on the future development of young scholars. At the same time, Liu Jiaoshou announced that he would take this meeting as an opportunity to prepare for the establishment of the "Interdisciplinary Dialogue and Parallel Research Center" of Shanghai Normal University.

The conference consisted of a keynote speech in the morning and two parallel workshops in the afternoon. Under the unified theme of "Chinese Etiquette Debate and Nakanishi Rei Studies", 21 lectures were given, which cleared up many problems and promoted the academic understanding and research of "Chinese Etiquette Debate" from various angles and fields.

Li Tiangang: "Debate on Chinese Etiquette" —— Research Method and Its Expansion

The keynote speech in the morning is divided into two halves. The keynote speech in the first half was hosted by Yuan Zhaohui, a researcher at the Institute of World Religions of China Academy of Social Sciences. Professor Li Tiangang of Fudan University, with the title of "Debate on Chinese Etiquette: Research Methods and Its Expansion", discussed four issues. The first one was about "Debate on Chinese Etiquette", and he emphasized that not only western documents but also Chinese Manchu and other oriental documents should be cited in the research methods and its expansion. On the second hand, he pointed out that the "Chinese etiquette dispute" is nominally about "ceremony" and in essence involves concepts, namely God and God, soul and Anima. In the third aspect, he said that the in-depth discussion of the "Chinese etiquette dispute" depends on the continuous advancement of the research paradigm, and in the process, we should open our minds to new knowledge; Finally, taking his new work Kanazawa as an example, he introduced his research in the context of the history of thought, mainly considering what is religion and what is folk belief, and the close relationship between religion and belief and the daily life of ordinary people.

Liu Yunhua: What is the relationship between European Enlightenment and China culture?

Professor Liu Yunhua of Shanghai Normal University gave a lecture entitled "What is the correlation between European enlightenment and China culture? First of all, taking Leibniz as a case, he analyzed and pointed out that although Leibniz had contact with China culture through missionaries, he explained the Confucian "reason" with his deistic view, rather than being influenced by it to achieve ideological transformation. Furthermore, he pointed out that the influence can be divided into implanted and confirmed. When talking about the enlightenment’s understanding of western core concepts such as freedom, equality and democracy, China culture has no implanted influence on the west, but only confirmed influence in the process of collision. Finally, he reconsidered the position of "science and technology" in the history of thought, and pointed out that most thinkers in China in the late Ming Dynasty were always confined to political correctness and could not seek truth from facts, and their understanding of western science and technology was really limited.

Mingde Wei: How to read China’s classics? From the perspective of "Nakanishi Rei studies"

The keynote speech in the second half was hosted by Ivan Ruviditch, director of the International Drama Studio of Shanghai Normal University and associate professor of comparative literature and world literature. Professor Mingde Wei of Fudan University’s report "How to Read China Classics? From the perspective of "Nakanishi Rei Studies", he thinks that "Jing" has the same meaning as the western Textus, and it is woven intentionally, so it must have a structure, so we can observe the Patterns in the structure in turn, that is, the structural Patterns and layout. On this basis, he specifically analyzes the patterns in various types such as structural rhetoric according to historical traditions. It also points out that when we contact the text, we need to regard the whole text as a style of existence and writing. And we should learn to understand a classic and put all these factors into its definite rhetorical structure, just to produce what the work itself contains in those who are ready to read it and endure its obscurity.

Song Lihua: The Encounter between the East and the West —— Guo Shi’s Hunting China in Chinese Novels

Professor Song Lihua of Shanghai Normal University made an in-depth study of Guo Shili’s works with the theme of "Encounter between the East and the West: China in Guo Shili’s Chinese Novels". By analyzing the image of China in his Chinese novels, he pointed out that although Guo Shili took Europe, especially Britain, as the frame of reference in describing China, China was excluded from the mainstream of European scientific, artistic and commercial development and became the object that needed European attention and even rescue. However, his words about China’s national character should not be simply regarded as a distortion of the facts, but should be understood as a historical event that really happened, because it once truly shaped the history and relationship between China and the West.

Zhang Yaonan: From "Debate on Etiquette in China" to Comparative Philosophy in China and Europe —— A Preliminary Study on "Debate on Etiquette" in the History of Comparative Philosophy in China and Europe

Professor Zhang Yaonan of Beihang University gave a report entitled "From the Debate on Etiquette in China to Comparative Philosophy in China and Europe —— A Preliminary Study on the Debate on Etiquette in the History of Comparative Philosophy in China and Europe". He pointed out that "Comparative Philosophy in China and Europe" refers to the comparative study between Chinese philosophy and Western philosophy. Looking at its history from Han and Wei dynasties to the present, it has experienced or will experience six periods. As the fourth phase of comparative philosophy between China and Europe, the debate on Chinese etiquette can be observed in six steps, and further summarized from a philosophical perspective, that is, "the debate on Chinese etiquette" and the "Enlightenment Movement" in western Europe are the same movement, and the themes debated are orthodox and heresy, atheism and deity, polytheism and monotheism, rationality and belief, wisdom and superstition, and self-reliance and self-reliance. It also emphasizes that the summary of Hegel’s "China’s Backwardness Theory" and "Historical Progress Theory" is not in line with the reality of Chinese studies and cannot be established.

On behalf of the National Day: the first voice of the debate on etiquette in China

The first half of the workshop was presided over by Wang Lingling, editor of Journal of Beijing Administration College. Professor Guo Qing on behalf of South China Normal University gave a report entitled "The Preamble of Chinese Etiquette Debate". He took the analysis of sacrificial rites from the perspective of Gao Muxian’s interaction with Chinese and Western Confucian classics as an example, and pointed out that in the recent history of cultural exchange between China and the West, Dominicans, as one of them, have always shown themselves as opponents of Chinese etiquette, highlighting their historical image different from Jesuits’ "adaptation strategy". In fact, it’s not that Dominicans didn’t reconcile Yeru. As early as when he preached in the Philippines, Gao Muxian focused on building a dialogue bridge between Thomas theology and Zhu Xi’s Neo-Confucianism, and applied it to the field of sacrifice. Gao Muxian’s comments on China’s sacrificial ceremony constitute the target of Domingo’s understanding of Chinese etiquette.

Wang Ding ‘an: The Separation of Chinese and Western Sacrifices and the Re-development of Comparative Confucian Classics during the Ming and Qing Dynasties

Associate Professor Wang Ding ‘an of Zhejiang University of Technology is entitled "The Separation of Chinese and Western Sacrifice Rites and the Re-development of Comparative Confucian Classics". He believes that the topic of "whether Mass is a sacrifice or not" during the Ming and Qing Dynasties was being staged fiercely in Europe at the same time, but it was not fully developed in China because of suppression. Now we re-examine the problems, beneficial experiences and the possibility of re-launching Comparative Confucian Classics with Aquinas’ sacrificial theology, which unifies "object" and "way". We can find that the difference between "being" and "being like being" presented by the sacrificial object is nothing more than a concrete manifestation of the relationship between God and man; The "way" of offering sacrifices to both Ye and Confucianism shows obvious sacredness.

Xiao Qinghe: Breaking away from the mundane and becoming a saint —— The Catholic narrative about saint in the late Ming and early Qing Dynasties

Xiao Qinghe, an associate professor at Shanghai University, gave a report entitled "Going from the mundane to the holy: the Catholic narrative about the holy in the late Ming and early Qing Dynasties". By analyzing the evolution of the meaning of the word "holy" and related terms, he clearly showed the process of cultural exchange, conflict and integration between China and the West. He pointed out that the missionary equated Sanctus with "Saint", which not only changed the meaning of Chinese character "Saint" and enriched the content of "Saint" since Ming and Qing Dynasties, but also changed the understanding of Sanctus in European Christian tradition, and the thoughts and spiritual worlds of both sides were blended and changed.

Ji Jianxun: The Origin of the Debate on Chinese Etiquette and the Relationship between Chinese and Western Learning Systems

Associate Professor Ji Jianxun of Shanghai Normal University, starting from The Origin of the Debate on Etiquette in China and the Relationship between Chinese and Western Learning Systems, emphasized that the "Debate on Etiquette" should not be a problem only related to the West or the East, and the new understanding should put it back in the historical coordinates of Sino-foreign exchanges, and the key to solving it lies in identifying the origin of the debate and clarifying the Chinese and Western learning systems behind the conflict. Confronting the problem of "etiquette dispute" and the "two-way" between culture, education and religion in China society revealed from it can help us better understand the two different cultures of China and the West and oppose the "clash of civilizations".

Yang Huiling: A New Probe into the Anti-ancestor Worship Thought in the Debate between Chinese and Western Etiquette in Qing Dynasty

The second half of the first group of the workshop was presided over by researcher Yuan Zhaohui from the Institute of World Religions of China Academy of Social Sciences. Yang Huiling, a researcher at the Institute of Advanced Studies in Comparative Civilization and Humanities Exchange of Beijing Foreign Studies University, took the topic "A New Probe into the Thought of Anti-ancestor Worship in the Debate between Chinese and Western Etiquette in Qing Dynasty" as an example, and studied his understanding and reinterpretation of China culture from the standpoint of Christianity by analyzing Li Yufan, a representative figure who opposed Chinese etiquette in the Debate of Chinese Etiquette in the Vatican Library. He found that he was equally familiar with it even if he held a position and viewpoint against China’s "ancestor worship" culture. Therefore, in the process of cultural exchange between China and the West in history, both sides of the exchange have the process of understanding each other and absorbing each other, rejecting and abandoning, seeing differences in the same, and seeking common ground while reserving differences and integrating and innovating.

Gao Shengbing: Matteo Ricci’s Cultural Identity and Its Translation Strategies and Effects

Associate Professor Gao Shengbing of Anhui University of Science and Technology gave a report on Matteo Ricci’s Cultural Identity and its Translation Strategies and Effects. He analyzed Matteo Ricci’s choice of "God", "Soul" and "Diligene/Caritas" (to love/. The cultural identity of "Western Confucianism" makes Matteo Ricci compare or choose Confucian concepts or words in his discourse, and the cultural identity of Catholic missionaries makes Matteo Ricci choose foreignization in concept translation. As the "other" of China culture, the translated words he chose can be widely accepted, which deserves our consideration.

Jian Wu: "Individualization" and "Cultivation" —— A Comparison between Jung’s Analytical Psychology and Taoist Inner alchemy

Jian Wu, a teacher of Jiaxing University, took "Individualization" and "Cultivation": A Comparison between Jung’s Analytical Psychology and Taoism’s Inner alchemy as the topic, and through the interpretation of the most concentrated and important commentary text of Jung on Taoism’s Inner alchemy, distinguished the fundamental difference between Jung’s psychology and Taoism’s Inner alchemy, and Jung’s misunderstanding of "The Purpose of Taiyi Jinhua". He pointed out that Jung’s psychology and Taoism’s inner alchemy are ideographic codes of two discourse systems, which represent two sets of thinking paths, and their speech objects are both internal experiences, so their differences are actually greater than their similarities. If we say that Jung adopted the method of "Geyi", it may not be an exaggeration to take me as the main analytical psychology when interpreting the Purpose of Taiyi Jinhua (including the Classic of Wisdom and Life) for his own analytical psychology.

Tan Jie: Words and deeds attest to Taoism —— Characters and moral education in "stories of testifying to Taoism" in the late Ming Dynasty

Associate Professor Tan Jie of Central South University’s report is "Words and deeds attest to the truth: the characters and moral education in the story of testifying to the truth in the late Ming Dynasty". By tracing back to the ethical tradition of the Renaissance, he placed the story of testifying to the truth in the Chinese translation in the late Ming Dynasty in the humanistic ethical tradition of the Renaissance. Through the analysis of two typical characters, "King Philip" and "Bi Da Lie La", he investigated its transmission by quoting the words and deeds of western sages.

Jia Weizhou: Confucianism-Confucianism in the Dialogue between Ye and Confucianism in the Late Ming and Early Qing Dynasties

The first half of the second group of the workshop was presided over by Dr. LIM Hyebin, a teacher majoring in comparative literature and world literature at Shanghai Normal University. Associate Professor Jia Weizhou of Guangdong University of Finance and Economics is entitled "Confucianism-Confucianism in the Dialogue between Confucianism and Confucianism in the Late Ming and Early Qing Dynasties", trying to return to the historical text and the specific context in which the problems occurred, so as to understand the reasons why the religious interpretation of Confucianism occurred in the dialogue between Confucianism and Confucianism in the late Ming and early Qing Dynasties, the starting point of different views, the methodology of hermeneutics and the results of the debate. This understanding will provide specific historical enlightenment to the discussion of religious interpretation of contemporary Confucianism. At the same time, the western Confucianism-Confucian view can reflect the attitude towards the whole culture of China, and we can also see the historical formation path of the western China view and China’s western view.

Jiang Xiaojuan: An Islamic Chinese Translator Influenced by the Debate of Catholic Etiquette

Dr. Jiang Xiaojuan of Fudan University’s report is "Islamic Chinese Translators under the Influence of Catholic Etiquette Debate". She started with the stimulation brought to Islamic scholars by a series of activities of Jesuit missionaries entering China, emphasizing that while they were hit hard, the Jesuits’ writing and speaking activities also inspired Islamic scholars, stimulating them to promote the localization of Islam in the same way, and a number of Islamic Chinese translators headed by Wang Daiyu emerged. They advocated the further development of Islam in China by interpreting Confucianism and explaining the similarities between Islam and Confucianism, which contributed to the further China of Islam.

Li Qiang: Christians in China and the Modern Evolution of the "Etiquette Debate" in the Early Qing Dynasty —— Focusing on the manuscripts in Xujiahui Library

Li Qiang, a doctor from Shanghai University, took the modern evolution of the text "The Debate on Etiquette between Christians in China and the Early Qing Dynasty" as a topic-focusing on the manuscripts collected in Xujiahui Library. In his report, he systematically combed the modern evolution of "The Debate on Etiquette" as a product, so as to illustrate the historical inevitability of modern Catholicism releasing the bondage of "The Debate on Etiquette" to Christians in China.

Wang Hongchao: Religion, Politics and Culture —— A Study of Yi-ology of Suoyin School and Missionaries in China

Associate Professor Wang Hongchao of Shanghai Normal University is entitled "Religion, Politics and Culture: A Study on the Yi-ology of Suoyin School and Missionaries in China". He pointed out that the study of Zhouyi by missionaries in China was deeply rooted in the biblical interpretation through the example that China Suoyin School founded by Bai Jin hoped to find the information of ancient China’s GOD from the Book of Changes and Jacob’s interpretation of "God" in the Book of Changes and other classics in the late Qing Dynasty.

Wang Niecai: Revelation or Reason? Two Opposing Interpretations of the Confucian Classics during the Rites Controversy

The second half of the second group of the workshop was presided over by Professor Du Wenwei, President of North American Oral and Performing Literature Research Association, Professor of Vassar University in the United States and researcher of China Opera Academy. Associate Professor Wang Niecai of Zhaoqing University took the book Revelation or Reason? Two opposing interpretations of the Confucian classics during the Rites Contraversy, this paper first introduces two different interpretations of the Four Books in the West, that is, the Franciscan Lian Dang (1602-1669) and the seal of Confucianism (1664) adopted an allegorical method to interpret the true meaning of China classics as the revelation of Christianity, while rejecting the traditional Confucian classics. And the Jesuits adopted the rationalism method in The Four Books of Western Languages (1687) to coordinate the western rationalism with Confucianism. Through the parallel comparison of the two concepts, it is very intuitive to show how these two explanations are rooted in different theological traditions, which leads to the two sides taking opposite positions in Chinese etiquette disputes.

Wu Rui: A Textual Research on the Origin of Oriental Etiquette in Shakespeare’s Plays

Wu Rui, a researcher at Shanghai Theatre Academy, gave a report on the Origin and Development of Oriental Etiquette in Shakespeare’s Plays. He pointed out that Shakespeare’s works involved a lot of oriental content and oriental protagonists, such as Cleopatra, Othello, and Shylock. According to textual research, the main drama conflicts in Romeo and Juliet also came from the legends of two rival families in the East. By exploring the origins of oriental rituals in Shakespeare’s plays, we can provide a path for the orientalization of Shakespeare’s plays.

Wang Qiyuan: Xu Guangqi’s Legacy in Shanghai and Its Contemporary Significance

In the report entitled "Xu Guangqi’s Legacy in Shanghai and Its Contemporary Significance", Wang Qiyuan, an associate researcher at Fudan University’s Chinese Ancient Books Protection Institute, thinks that, as a first-rate figure who walked out of Shanghai in modern national history, if these places in Shanghai related to Xu Guangqi can’t be fully studied and developed, it is indeed a slight violation of the actions of the sages. Therefore, he made an in-depth investigation of Xu Guangqi’s legacy in Shanghai through the publication of a large number of local documents such as the "Shanghai Fu County Old Records Series" compiled by Shanghai Local Records Office and Tongzhi Museum.

Du Wenwei: On the Mutual Influence of Eastern and Western Cultures from the 90-year History of The Story of Grey Lan

Professor Du Wenwei, with the theme of "Looking at the Interaction between Eastern and Western Cultures from the 90-year History of Grey Lan Ji", systematically combed the spread and evolution process of Yuan zaju "Grey Lan Ji", and concentrated on analyzing the theme changes of "Grey Lan Ji" through various stage adaptations. He pointed out that the spreading history and the changing process of the theme reflected the mutual influence between the themes of eastern and western cultures and drama theory, and in this long-term mutual influence process, The Story of the Grey Lanji not only became a historical drama that was performed circularly on the eastern and western stages, but also spawned some modern dramas.

The results of this workshop are quite fruitful, and the teachers and students attending the workshop have had a heated discussion, which has made a great breakthrough in the paradigm and content of promoting the study of "Chinese etiquette dispute". I believe that there will be significant progress in the near future, and a brand-new and in-depth "Nakanishi Rei study" is taking shape. In December 2018, the Center for Comparative Literature and World Literature, a national key discipline of Shanghai Normal University, held the first forum of "Interdisciplinary Dialogue and Parallel Research", which aroused widespread concern in academic circles. On the basis of the first forum, this workshop is another academic grand meeting with the innovative mode of "interdisciplinary dialogue and parallel research", thus further contributing to the construction of the first-class discipline of China Language and Literature in Shanghai Normal University and making new contributions to the academic innovation of humanities in China.

In terms of research paradigm, scholars’ research shows that the academic discussion on "Chinese etiquette dispute" is starting from the field of history and turning into the fields of literature, philosophy, culturology and religion, showing a trend of multi-paradigm transformation; In terms of research content, the series of results of this workshop also show that the series of debates between Chinese and Western civilizations are ostensibly centered around "Chinese and Western etiquette", which is behind the differences and dislocation of the core concepts of the two heterogeneous civilizations, namely "keywords". These studies can be done from point to area, with a clear sense of problems, and provide important reference for the current in-depth exchanges and dialogues between China and foreign countries.

Can artificial intelligence speak "foreign languages"? -On Natural Language and Computer Language

Language is an important tool for human beings to express their communication and thinking. Language reflects people’s thoughts, and people use language to communicate, express and create. The daily language used by human beings is called natural language, which includes vocabulary, pronunciation, semantics and grammar. The language used for machine programming is called computer language, which consists of numbers, characters and grammatical rules. Human natural languages are in different languages and belong to different language families, and computer languages are also divided into various categories according to different writing rules. Language intelligence, the ability of people to communicate and think in writing through language dialogue, is regarded as an aspect of human intelligence. In contrast, a machine (computer) has the ability to recognize computer language, run programs and perform operations, and computer language can be regarded as a language inherent in the machine. If the computer can understand the natural language as a "foreign language", realize the translation of natural language, understand and execute people’s commands, and even talk to people, can it be considered that the computer has language intelligence similar to that of people? This paper will answer this question.

Definition of natural language and computer language

The language used in human daily life is called natural language. Humans use language to express ideas, communicate and describe objects. As a carrier, language carries the connotation of words. Many languages of human beings belong to different language families, but languages can correspond and translate with each other. Every language is a system including vocabulary, grammar and pronunciation, in which vocabulary is used to express itself according to grammatical rules. As the philosopher and linguist Chomsky said in Language and Mind, "People who know a certain language have mastered a set of rules system, which assigns sounds and meanings to countless possible sentences in a certain way." However, individuals who use natural language may not be aware of the rules and connotations of this language system: "People who know the language are not aware that they have mastered these rules or are using them, and there is no reason to assume that this knowledge of language rules can be brought into consciousness."

The acquisition of natural language is based on life and social interaction. The process for children to master a language is to get in touch with words and sentences through a large number of dialogues, acquire sentence models in conversations and chats, and then master grammar. It can be seen that the learning of natural language is from semantics to grammar. Therefore, some scholars discuss language acquisition from the standpoint of human language talent theory. For example, Chomsky thinks that there is a natural universal grammar in the human brain, which exists in a place called language acquisition device. He tried to explain the relationship between language research and human nature, and thought that language reflected the process of human mind and determined all aspects of ideological characteristics and development.

From the perspective of language system, natural language is both stable and changeable. On the premise that a language exists, its vocabulary and basic grammar are stable. At the same time, the language is constantly updated, derived and developed due to the changes of the times and environment during its inheritance and use.

Computer language refers to the language that uses numbers and characters to write programs according to the prescribed grammatical rules, so that computers can do all kinds of work. It includes machine language, assembly language, high-level language and so on. In different ways of thinking about programming and programming models, statements composed of characters and grammatical rules perform operations according to instructions. The original intention of computer language design is to enable people to better control and operate computers. At present, every action and step made by all computers are carried out according to the program compiled by computer language. The operation of a computer is a process of accepting input, matching objects and outputting answers. In the execution operation, the calculator must first understand the input commands of people, and translate the natural language. The source code of the application program is translated into the target code machine language by the interpreter of the corresponding language, and then the compilation operation is carried out to translate the program source code into the target code machine language.

It can be said that computer language is the medium of man-machine dialogue. Computer language can recognize and translate natural language, perform operations and output results in its construction, and the translation process is the key to man-machine cooperation and even man-machine dialogue. The machine can only continue to perform operations after understanding the commands input by human beings. Before the emergence of intelligent machines, people’s input instructions to machines were single, but today’s intelligent machines have gradually tried to understand people’s commands through voice and image recognition. At present, this ability mainly depends on corpus analysis, enhanced matching search and deep learning.

If the vocabulary of natural language is regarded as a set of symbols and its grammar is regarded as the rules for the use of symbols, then computer language is also the use of symbols and rules. The encoding and decoding of computer input and output, as well as the operation in human-computer interaction, are also similar to the process of using language to listen, read, write and communicate with people. In this sense, computer language seems to be the natural language of computers. If the computer is truly intelligent, then in its view, human natural language can be regarded as a foreign language. But can computers be intelligent?

To compare natural language with computer language, an important perspective is to distinguish the internal logic of natural language and computer language from their logical systems. Logic is an important connotation of language, and the logical structure and grammatical system of a language are the root causes that distinguish it from other languages and languages.

Logic in Natural Language and Computer Language

In the use of natural language, ambiguity and ambiguity are inevitable, and there are misunderstandings and deviations in translation between languages. Scholars want to solve the ambiguity and ambiguity of words in expression and find the common deep structure in human language, so they invented formal language by using mathematical methods for reference. The original intention of formal language is that people want to make logic have a set of universal symbols like mathematics, so as to try to establish a universal and unambiguous language. Through this language, all thinking and reasoning can be transformed into calculus and become as accurate as mathematics. Logicians try to accurately describe the world described by natural language with formal systems and symbols, so as to make more accurate reasoning, analysis and judgment. Therefore, in the study of logical language, it also includes the study of natural language generative grammar.

Natural language can be regarded as a symbol system, in which words are symbols to express ideas under the cultural background. However, the logic in natural language is not only grammatical structure, but also semantic. The ambiguity and vagueness of some words in our daily expression are difficult to judge in grammar, but they can be simply solved by context and the introduction of context. Wittgenstein thinks that natural language is used to express objects, the meaning of a proposition or sentence comes from its real object, and the process of learning language is to master the relationship between words and objects. We can’t get meaning from a single word, but through association and activity, so natural language has meaning under certain environment and specific rules of the game.

Therefore, the logic of natural language has one more dimension than that of formal language. Natural language is a part of human mind, and the logic contained in words is the unique logical ability of human mind. As Wittgenstein pointed out, a single vocabulary and grammatical structure cannot convey complete meaning. The acquisition of natural language can’t be achieved only by learning the logical structure of language. Therefore, mind is an important concept in the acquisition of natural language.

The computer language used by the machine is also a formal language. It is the language that people first gave to the machine and became the pre-existing language in it. When computers understand and execute human commands, they need to translate natural languages into computer languages that can be understood by machines, and then carry out program operations. Formal description of natural language is very important for mechanical imitation of computer programs, but understanding imitation is different from mechanical imitation. Mechanical imitation involves formal nature, while comprehension imitation involves quasi-semantic nature. At present, computers are mainly based on mechanical imitation and talk to people’s natural language through logical language. Therefore, although the processing of natural language by computer can be regarded as a kind of translation, at present, this kind of translation is different from the mutual translation between two languages in natural language.

In the process of disambiguation, computers need a lot of knowledge, including linguistic knowledge (morphology, syntax, semantics, context, etc.) and common sense cognition about the world. This has also caused two main difficulties in natural language processing at present. Measuring computer language from the perspective of natural language is highly formalized, which makes its ability to describe context limited, and it cannot convey multi-layer information like natural language. Therefore, although formal language has advantages in accuracy, its contextual shaping ability and expressive power are inevitably weaker than natural language. In the understanding of natural language, it is difficult for formal language to fully describe how lexical devices are related to syntactic structures, thus forming the meaning of sentences, which is also an important reason for errors in computer recognition of natural language. Of course, with the development of corpus construction and corpus linguistics, the rationalism method based on syntactic-semantic rules, which was mainly used by computers in dealing with natural languages, has taken a back seat. Nowadays, the natural language processing technology has introduced statistical mathematics methods, and gradually reduced errors with the support of matching search and automatic learning methods.

Cognitive science holds that thinking and cognition are logical operations of knowledge, while computerized natural language analysis mainly depends on the expression of logical language. From the perspective of behaviorism, if the machine has a computer language, and it is constantly strengthened and more accurate in the operation execution and use the day after tomorrow, it is a kind of acquisition and consolidation. In this sense, computer language seems to be its natural language for computers. However, although natural language and computer language each contain many kinds, the reasons for their diversity are different. Different from the differences of history, culture and region, computer language is developed for different needs when writing programs. Therefore, the connotation of natural language and computer language is different. Fundamentally speaking, the mind embodied by natural language is different from that expressed by computer language.

Natural language and mind

If natural language is the tool of human expression and the medium of thinking, then the relationship between natural language and mind is inseparable. To a certain extent, people’s ability to use language is one of the manifestations of mental ability. Mind is different from intelligence. Mind is a part of intelligence, which refers to people’s abilities of perception, feeling, memory, learning, understanding and innovation.

Mental ability includes the understanding of natural language. When using natural language in daily life, we can get the pronunciation, image and connotation of the described object at the same time. In our daily life, whenever we hear someone describe something or see someone pointing to an object, we will remember what this thing is called and say the same words when we refer to that thing again in the future. We can also experience all kinds of emotions and feelings in the sentence from other people’s voices, movements, expressions and eyes, as well as body movements, tones and tones. That is to say, in natural language, the meaning of words is not limited to the meaning of a single word, but also includes the appearance of the referent, pronunciation, the intention of the narrator and the context at that time. The meanings of natural language are fully embodied in social communication and dialogue. A comprehensive grasp of these meanings requires mental ability, and vice versa. As Chomsky said: the surface rule of words forming sentences is grammar, but the real meaning of sentences is reflected in the deep structure. The deep structure is related to the surface structure through some mental operations. In other words, the connection between all words, sounds and meanings of natural language is based on the grammatical structure on the basis of mind.

Furthermore, the study of natural language is also a reflection of mental ability. Psychologists represented by Chomsky believe that language and grammatical structure are the essence and characteristics of human mind. No matter how different language users are in individual experience and ability, they will complete the task of constructing language theory system in a very similar way. We are endowed with cognitive structure and language ability in our minds, and gradually strengthen our grasp of grammar rules in the application of acquired knowledge. "On a basic level, we humans are not learning languages. The real situation is that languages grow up in our minds."

Different from Chomsky, Quine’s language theory is based on empiricism and behaviorism. He opposes both the thorough empiricism reductionism and the pure transcendental knowledge. He believes that the reason why language can express meaning depends on the acquisition of behavior, and people’s mental ability embodied in language behavior is gradually acquired. The mental ability to master and use a language is acquired and can be strengthened through training. In Quine’s view, our ability to master language comes from public knowledge, which is a kind of inheritance of human common experience and knowledge background, rather than a priori existence: "Even if we want to talk about a unique quality of sensory awareness, most of us have to turn to public objects, the color of oranges, the taste of rotten eggs, and so on. To continuously access the previous sensory data, it also depends on the reference object. Of course, we should explore the sensory awareness and sensory stimulation behind the daily discourse about objects, but these are the background of concept formation or language, not their underlying structure. "

According to Chomsky’s theory, the initial inner nature that we give to an intelligent computer can be counted as its innate "mind", of course, such a mind is given by people and is incomplete. According to Quine’s theory, under the premise of being constructed, the computer has acquired the knowledge background and can continuously strengthen its language ability in learning, which seems to mean that it is possible to obtain real intelligence in intensive learning, including the same level of language intelligence as people.

Machine language and mind

In the famous Turing test of artificial intelligence, if a person can have a long enough conversation with a machine, if the interlocutor can’t tell whether the answer comes from a machine or a person, then it is judged that the machine is intelligent. It can be seen that the main ability of Turing’s intelligent computer is the ability to understand and use language. The test defines the intelligence of the machine as several aspects: the machine should be able to answer the questions of input text; Be able to explain the meaning of words; Able to understand sentences composed of words; Be able to translate one language into another. Language ability is an important criterion to judge whether a computer has intelligence. It can even be said that from the mechanism of Turing test, language ability can be equated with intelligence.

If intelligence must master language ability, as mentioned above, although the natural language used by human beings has vague and ambiguous contents, its expressive power is indeed stronger than that of formal language. If a computer wants to have real intelligence, it must have the ability to understand natural language in different contexts. However, this ability is almost impossible in the existing technology. Dreyfus mentioned in What Computers Can’t Do that one of the difficult problems for machines to acquire intelligence is to solve the ambiguity in language. Although there is now the support of enhanced matching search and big data, the ambiguity problem of natural language has been partially solved on the surface. However, if we can really understand and use a language by referring to the way we use natural language, we need to master the necessary reasoning rules (including expert knowledge reasoning and common sense reasoning), but also have the ability to understand and comprehend the context. With this ability, you can be considered to have a mind and intelligence.

When discussing machine intelligence and mind, many researchers hope to get inspiration from the generation and structure of human intelligence. From simple development to complex thinking, human intelligence seems to have rules to follow, but if you consider it carefully, even the simplest and most elementary intelligence involves the cooperation of millions of brain cells and muscle cells on a large scale. These simple behaviors are embedded with too much intelligence, which are deep mental abilities that are not realized in daily speech and behavior. Language intelligence, as one of them, if we consider the source of language mechanism and its role in the sudden qualitative change of human intelligence, at least two basic problems will appear: first, the core semantic content of the smallest meaningful element, including the simplest element. Second, the principle of allowing unlimited combinations of symbols. If we want to analyze the physiological structure and logical structure produced by human mind step by step, we will try to endow the machine with mind by imitating this structure. It is bound to face two dilemmas: first, the human brain is a black box that cannot be completely mastered; Second, the mind, as a non-physical but real existence, is an elusive existence for technology.

From the standpoint of mentalism, it is impossible for a computer to have the same mental ability as human beings, although it can acquire more sophisticated and accurate natural language processing technology with the development of technology, and it can understand all instructions of natural language in operation and execution. From the standpoint of behaviorism, if a machine has the same language ability as human beings and can understand and express natural language, it seems that it can be considered as a machine with mind. However, the inevitable problems in the transformation between natural language and formal language also indicate that imitation based on behaviorism cannot be exactly the same as human beings.

conclusion

With the development of technology, the number of natural language texts that can be processed by computers has been increasing. Under the application requirements of text mining, information extraction, cross-language information processing, human-computer interaction and so on, the research on computer natural language processing is also advancing. However, natural language is directional and logical in description and expression, and conveys and carries culture. This means that natural language is not only a combination of some words and symbols, but also different from formal language. Although natural language is also used under certain logical grammar and has the functions of communication, exchange, expression and creation, it also has cultural attributes. The acquisition of a language not only includes the use of words and grammatical rules, but also includes the understanding and recognition of a culture. At this level, no matter how much the existing intelligent machines deal with natural languages, they have not yet possessed real intelligence. Therefore, we can take the normal use of language as extremely clear empirical evidence to prove that other creatures have the same mind as us, but not as discriminatory evidence of the source of mind and human ability.

Descartes said that "language is the core symbol of human thinking", which means that language ability and human thinking ability are inseparable and language ability is the representation of human mind. He also pointed out that two important abilities of human mind, understanding and will, cannot be realized by machines (automata). Because the mind has no substance, it is impossible for automata to create the mind by imitating the surface structure anyway. Descartes’ prediction is still correct today, although it lacks the integrity of argument. The use, expression and creation of language is an important content of human intelligence. If the intelligent machine in the future will have the same or even stronger intelligence as human beings, then it must have the same understanding and application ability as human language ability. This can’t be done at the existing computer language level. As for whether machines can learn "foreign languages" by new breakthrough technologies in the future, that is another question.

The National Bureau of Disease Control and Prevention said that the epidemic situation in COVID-19 may rebound around the Spring Festival, and the harm of new strains will be explained in detail.

Lian Junxiang and Xu Hanyi recently held a press conference in the State Council Press Office. The relevant person in charge of the National Bureau of Disease Control and Prevention said that due to the sharp increase in personnel flow during Spring Festival travel rush, it is expected that the epidemic situation in COVID-19 may rebound to some extent before and after the Spring Festival, and many respiratory diseases will continue to appear alternately or jointly in many parts of the country.

So, what is the toxicity of the new strain JN.1 in COVID-19? Will influenza and COVID-19 cross-infect?

one

The number of people infected with JN.1 strain in China is increasing.

According to the data of China Center for Disease Control and Prevention, the number of cases in COVID-19 increased from the end of last year to the beginning of this year.

On January 6th, this year, the number of newly confirmed cases exceeded 10,000 for the first time, reaching 10,684. The number of positive detections in the last week has increased significantly.

At present, the mainstream strain is still EG.5 and its subfamilies, but the number of people infected with the latest JN.1 strain is increasing. As Spring Festival travel rush is coming, the epidemic of the virus may still be variable.

2

The mortality of new strains in COVID-19 is not high.

So, how harmful is the latest JN.1?

According to the global data, the spread of Covid-19 JN.1 is rapid, but the risk has not improved.

JN.1 is a second-generation subfamily of Omicron BA.2.86 mutant, which was first detected in Luxemburg at the end of August last year.

According to the latest data from GISAID, JN.1 began to spread around the world in November last year, and it took only one month to become the global mainstream strain, accounting for 50% of the new cases every day. At present, this proportion has exceeded 70% and spread to at least 59 countries and regions around the world.

The rapid transmission is also reflected in the level of virus activity in wastewater. The higher the value of this indicator, the wider the spread of the virus.

According to the data of the US Centers for Disease Control and Prevention (hereinafter referred to as CDC), the concentration level of Covid-19 in wastewater in the United States was 12.85 in the week of December 30th, reaching the second highest level in history since the outbreak of COVID-19 epidemic in the United States.

According to relevant scholars, compared with the previous Covid-19, JN.1 virus has acquired a key new mutation, so its spreading ability is stronger.

Judging from the hospitalization and mortality, the influence of JN.1 did not exceed that of the previous strain.

According to the data of CDC in the United States, in the week of January 6th, there were 35,800 new hospitalized applicants in COVID-19, with an average of about 11 per 100,000 people.

Although the trend has increased, it is not too serious compared with the previous peak. At the beginning of 2022, the number of people applying for hospitalization in the United States due to Covid-19 infection peaked at about 45.5 per 100,000 people, which is 4.4 times of the current level.

Judging from the death situation, the number of people who died of COVID-19 infection in the United States is decreasing.

In the week of January 6th, the number of people who died of Covid-19 infection was 0.3 per 100,000 people. Last year’s peak was 1.2/ 100,000 people, which is also about four times the current level.

If compared with 2020, the gap is bigger, about 26 times as much as the current one.

three

It is unlikely that influenza will merge with COVID-19.

At present, the positive rate of influenza virus detection in China has declined, but among them, the proportion of B-stream is increasing, and the proportion of mixed infection is increasing recently. It may be infected at the same time, or it may be that "A stream is just right and B stream is recruited".

According to the data of China National Influenza Center, in the first week of 2024, the proportion of mixed infection increased to 36%, compared with only 12.4% a month ago.

With the spread of JN.1, will people who have had the flu still be infected with COVID-19?

Judging from the research data, it is possible, but the proportion is not high.

According to a paper published two years ago by scholars from the University of Aix-Marseille, 54 related studies around the world were collected and analyzed, including the data of about 18,000 patients infected with COVID-19.

The results showed that only 0.7% of the patients were co-infected with COVID-19 and influenza, that is to say, only about 140 of the 18,000 patients were co-infected with Covid-19 and influenza virus.

But compared with B-stream, A-stream is more likely to be infected with COVID-19.

The data showed that among 143 patients with concurrent infection, 74% were infected with influenza A, 20% were infected with influenza B, and only one patient was infected with three viruses at the same time, with a low probability. Refined to the age of patients, children are more likely to be infected than adults.

The data shows that the proportion of children with infection is 3.2%, which is about 10 times as much as that of adult patients (0.3%).

four

Complicated with infection or aggravated illness

Although the possibility of concurrent infection is very low, once infected, it may aggravate the condition.

As early as 2021, the national key experiment of virology found that in the experimental mice, co-infection would cause more cells and tissues in the body to be attacked by the virus, which would lead to more serious lung pathological reactions, a large number of cell infiltration and obvious alveolar necrosis [2].

From the comparison of patients’ data, co-infection does lead to more serious symptoms of patients.

According to the paper published by Nanjing Medical University in 2022 [3], compared with patients infected with COVID-19 alone, patients with combined infection are more likely to need a ventilator, and the risk is 2.31 times that of patients infected with alone.

Among them, the risk of using a ventilator with COVID-19 and H1N1 infection is higher, which is 5.04 times that of single infection.

Symptoms mainly focus on respiratory complications, such as acute hypoxic respiratory failure, acute respiratory distress syndrome, heart injury and acute kidney injury.

Not only that, patients with infection are also more likely to live in ICU.

Research shows that [3], the risk of patients with co-infection staying in ICU is 2.09 times that of patients with single infection.

According to the paper published in the International Journal of Epidemiology in 2021 [4], in the face of co-infection, the elderly population is more likely to be seriously ill and more likely to cause life-threatening.

For example, among patients aged 50-59, 60% were admitted to ICU after infection, while the proportion of single infection was 24%. In patients aged 80 and above, the proportion of death after infection was 66.7%, which was also higher than that of single infection (46.5%).

However, co-infection may not increase the risk of death. Studies have shown that [3], there is no significant correlation between co-infection status and death.

Including the elderly, children and high-risk groups with basic diseases, it is necessary to pay attention to timely differential diagnosis and take related drugs after symptoms of upper respiratory tract infection, so as to alleviate symptoms, shorten the course of disease and reduce the risk of severe illness and hospitalization.

The highest price is over 300,000. Are these official modified cars of tank 300 expensive?

The appearance of Tank 300 not only enhances the strength of independent automobile brands in the hard-core off-road field, but also promotes the progress of domestic automobile modification culture to a certain extent. There are as many as four "officially modified" models. Today, let’s take a look at what’s special about these four cars.

The first paragraph, tank 300 tank ranger

Guide price: 253,800 yuan

Co-brand: Yunliang Off-road

This is the first official customized model of the tank 300 in the true sense. It was built by the domestic modified brand Yunliang off-road, and the first batch of models were launched in August 2021. In appearance, the design elements of the tank 300 are largely retained, but the front and rear metal stamping bars and metal side bars are replaced, so that the protection of the car body is more in place, and a winch for rescue or extrication is added to the front bar. Tires and wheels have been replaced with off-road models, and nitrogen shock absorption has been replaced, which can cope with extreme road conditions more calmly. The A-pillar of the vehicle is equipped with a wading throat, and the wading depth can reach 900 mm. The second batch of models that are being booked have also added a trailer power inlet, a trailer square opening and an air conditioning entity button, which further improves the practicality.

(2021 Tank Ranger)

In the interior of the car, Tank Ranger also retains most of the design elements of Tank 300, but its performance in comfort configuration is relatively common. Steering wheel heating and Yanfei Lishi audio are not equipped with these two ordinary high-profile models. In addition, the seat is made of imitation leather, and the front seat has only heating and no ventilation function. It seems that the name of tank ranger is unreasonable, and he is a veritable "rough man".

(2021 tank ranger interior)

The second paragraph, the tank 300 wind forest fighters

Guide price: 270,800 yuan

Co-brand: Top Fire

Compared with the tank ranger, the change of Fenglin Iron Rider is bolder. In the front face, the middle net is changed to a simple double rectangular style, and the grille is denser than before, which can better block the impact of flying stones on the condenser. The air inlet is added to the hood, which makes the visual impact stronger. There is no wading throat at the A-pillar position, which will affect the wading height of the vehicle, but the overall feeling is stronger. The front bumper, side bumper and rear bumper of the vehicle have all been changed. After all, this is one of the most attractive places for a hard-core off-road vehicle. It is worth mentioning that this car is equipped with 285/70 R17 wide tires, the tires are basically flush with the wheel cover, and the visual effect is excellent. Such a hard-core tire configuration, of course, requires better suspension shock absorption, and Fenglin Tieqi is also equipped with nitrogen shock absorption and other configurations to improve the passability of vehicles. In addition, the roof is equipped with a luggage rack platform decorated with the words "TOP FIRE", which shows the identity and has strong practicability.

The interior hasn’t changed much, but the higher price compared with tank ranger gives it enough cost space to upgrade in comfort configuration. Steering wheel heating and front seat heating and ventilation are arranged, and the seats are made of leather, which makes the touch more comfortable. This car is also equipped with a PM2.5 filter in the car, as well as the addition of Yanfei Lishi audio and 64-color ambient lights, so that you can be very comfortable in the off-road process. It is also a practical function for camping enthusiasts to bring their own 220V power supply. The first batch of Fenglin fighters gained a good reputation, which also made people look forward to the improvement of the second batch of Fenglin fighters.

Paragraph 3, Tank 300 Border Limited Edition

Guide price: 280,000 yuan

With the cooperation experience with famous domestic off-road refitting brands, Great Wall Motor has also started to upgrade its original factory. This border limited edition model is a typical example, which basically combines the advantages of Tank Ranger and Fenglin Iron Rider. In terms of appearance, the front of this car abandoned the traditional TANK LOGO and replaced it with the simple English letter "Tank". At the same time, the middle net was changed to a black honeycomb style, and the sports atmosphere was improved. The front bumper has been upgraded to a competitive bumper, and the rear bumper has also been optimized. Its approach angle has reached 36 degrees, while its departure angle is 37 degrees, which is the largest among the official models of the 300 series of tanks at present. The front bumper is also equipped with a winch, the wading throat is also equipped, and the roof is equipped with an expandable roof platform, which is more comprehensive.

The interior part of the car basically maintains the configuration of the original high-profile model of the tank 300. Compared with the Fenglin Iron Rider, the front multi-storey sound insulation glass is added, which further improves the sound insulation effect of the vehicle. As an official-reformed vehicle independently developed by Great Wall Motor, the price of the limited edition of Tank 300 Border came to 280,000 yuan. It seems that Great Wall Motor is still quite emboldened. Do you think this price is worth it?

The fourth paragraph, tanks 300 cyber tanks

Guide price: 308,000 yuan

Co-brand: Chaojing

This is the only model of Tank 300 that has been modified to the urban SUV style. If the previous model is regarded as a competing product of herdsman, then this Cybertank is a competing product of Mercedes-Benz G. Although the prices of the two are very different, the styles are relatively close. The appearance of tough sports with gorgeous interior will bring about a turning back rate that is basically no less than that of a supercar. This cyber tank basically only retains the powertrain and chassis of the basic model, and the rest of it has undergone drastic changes. In the net, the penetrating headlights are added, and the car paint with matte gray is matched, so the overall look has a strong sense of science and technology. The wheel eyebrows are changed to the same color as the car body, and the integrity is better. The roof and rearview mirror are decorated with bright colors to enhance the sense of fashion. There is a big bump in the center of the hood to enhance the visual impact. The spare tire is no longer hung at the rear part of the car. Instead, it is a square suitcase with a larger spoiler at the top, but it is mainly used for decoration. Tyre size is 275/45 R21, with a relatively high face value, but it basically does not have off-road ability. Even if it crosses the speed bump or bumps, it is necessary to close the throttle, otherwise it will easily cause tire bulging.

The biggest change in the interior is the use of pure white color matching. The seats, center console and door panels are mainly white, followed by a large number of chrome-plated decorative pieces. The visual effect is excellent, but it is really not resistant to dirt. The stitching of leather seats is exquisite, and the sense of luxury is in place. According to legend, this is the most expensive model in the customized version of tank 300. Can you accept the price increase of such a model with a main face value?

These are the four special models of Tank 300 on sale. Although the price is much higher than that of the ordinary model, these models are equipped with hard-core configurations such as front and rear axle differential lock and part-time 4wd, which can meet the individual needs of different consumers. If the budget is enough, which one would you choose? In addition, this successful model of tank 300 is likely to continue to other models such as tank 500. Do you expect it?

Marketing or real use? Robots make table tennis more possible.

  Core reading

  The table tennis robot demonstrates the powerful "behavior" ability of artificial intelligence. In the future, with the upgrading and maturity of table tennis robots, it will help athletes to train better and promote the popularization of table tennis.

  Some time ago, a video of "the longest ping-pong round in history" released by the ITTF aroused widespread concern among fans on the Internet. In the video, professional players and table tennis enthusiasts use different tools such as rackets, spatulas and books to relay the ball back in different environments, and staged an interesting table tennis party.

  Nowadays, the application of artificial intelligence technology has inserted the wings of imagination into table tennis. A table tennis robot with a smart "brain" is constantly challenging. Will it defeat the table tennis world champion?

  Help popularize sports.

  In 2014, German table tennis star Bohr faced a table tennis robot named KUKA. In the face of robots, the former world No.1 player took high gear and low gear, but he could only rely on tennis balls and edge balls to keep up with the score and finally win narrowly. Although this duel is only an advertising marketing, the level of robots was not very strong at that time, but the seeds of imagination have been planted in the hearts of researchers.

  China Table Tennis Institute of Shanghai Sport University cooperated with Xinsong Robot Automation Co., Ltd. to develop two generations of Pongbot table tennis duet robots. Although the fighting robot has only one mechanical arm, it can already achieve man-machine combat. At the same time, through the deep learning and reinforcement learning model in the artificial intelligence algorithm, the robot can "study" the opponent’s movements and hitting methods while playing, and formulate the return strategy by predicting the table tennis trajectory.

  Deng Yaping, the Olympic champion of table tennis, once competed with the second-generation duet robot in a TV program, testing the performance of the robot from three dimensions: speed, strength and rotation. From the beginning of the "helpless" when facing the fast break, to the end, the robot can successfully catch the difficult backspin ball. After one or two hundred rounds of fighting, the robot has shown strong adaptability and learning ability. "Table tennis robots have great potential and cannot be underestimated." Deng Yaping said.

  In fact, robots have been widely used in medical care, automobile, chemical industry, education and other fields. In the field of sports, there are also companies that have produced robots that can complete gymnastics movements. Ren Jie, vice president of China Table Tennis Institute of Shanghai Institute of Physical Education, who participated in the research and development of table tennis robots, said that the original intention of designing table tennis robots was to use scientific and technological means to help athletes train better and promote the popularization of table tennis.

  Strong learning ability

  In March of this year, Pombert played against the robot’s "brother" product — — Serve robot comes out. The service robot has two mechanical arms, which can throw the ball with one hand and hit the ball with the racket in the other. Compared with the traditional service machine, the service robot highly restores the service action of real people, provides athletes with time to observe their opponents, and exercises their reaction ability and ball handling ability.

  However, in order to achieve a high degree of personification, in addition to the appearance and action, we must also realize the variety of service. Ren Jie introduced that the service robot can set different rotation types and landing points of the ball, and can simulate different playing styles through the quick change of the racket. "After practicing such a combination, I feel as if I am playing against a real person, or a master!" An experiencer lamented.

  The "trump card" of the serve robot is the function of trajectory analysis and action analysis. Two distributed binocular vision systems are like a pair of "smart eyes", which can capture the trajectory of the ball and the athletes in time. Coupled with the "brain" of artificial intelligence algorithm for deep learning and timely adjustment of technical and tactical strategies, a set of "combination boxing" makes the service robot "smart".

  "If you beat the human Go master ‘ Alpha dog ’ Show us the powerful artificial intelligence ‘ Thinking ’ Ability, the table tennis robot shows the powerful artificial intelligence ‘ Behavior ’ The ability reflects the manufacturing strength in the field of industrial automation in terms of accurate identification, rapid response and flexible control. " Ren Jie said.

  With a deep understanding of table tennis, China Table Tennis Institute has avoided many detours in the process of cooperative research and development of table tennis robots. At the beginning of the design, the serve robot was set at a very fast speed. Later, it was found that this exceeded the acceptance ability of most athletes, which not only failed to achieve the exercise effect, but also increased the configuration of motors and motors, which was completely unnecessary. "Technology research and development should conform to the laws of reality." Ren Jie said, "So we suggest debugging the robot with reference to the speed, frequency and rotation of the ball when the coach conducts multi-ball training."

  Wide application prospect

  In the past table tennis class, 20 students shared 10 tables. If the teacher practiced multi-ball training one by one, it was often difficult to take care of all the students in one class. Gu Nan, director of the training department of China Table Tennis Academy, said that after the school starts, the college will put 10 service robots into classroom teaching. Through personalized settings, each student can carry out targeted training in a mode suitable for his current level. In this way, teachers have more time to guide students.

  Robots can assist teaching, can the training object be robots? China Table Tennis Academy makes serve robots and duet robots become "apprentices". The former uses professional training mode and flexibly adjusts course training according to the progress level of apprentices. The latter quickly learns different return strategies.

  If the goal of the duet robot is to beat the world champion of table tennis, then the service robot takes the route of "being close to the people", which is more suitable for ordinary table tennis lovers to practice basic skills. In the future, in addition to daily teaching, service robots can also enter community fitness centers, table tennis clubs and so on. With such a machine, one person can also play ball. If you set the relevant data, you can have a hearty duel.

  Ren Jie imagined that in the future, with the help of technologies such as 5G and AR (augmented reality), robots may also be able to synchronize the movements of the participants at the other end of the line in real time, realizing the "cloud battle" of table tennis matches, making table tennis break through the limitations of time and space and become more interesting. Shi Zhihao, dean of China Table Tennis Institute of Shanghai Sport University, hopes to lead the development trend of table tennis in the world through the combination of artificial intelligence technology and table tennis. At the same time, in the process of upgrading the related products of table tennis robots, more technological innovations will be applied to the cultivation of high-level table tennis talents.
