Dialogue Yu Yongfu: Ali literature grows faster than friends, not by selling copyright.

"Yes, we are confident that the integration of Youku in the first stage was successful," said Yu Yongfu, chairman and CEO of Alibaba Entertainment.

It is true that the volume of Youku’s voice in the market is obvious to all. According to the data of the third-party platform Guduo, from Q2 to Q3 this year, the number of new dramas played by Youku far exceeds that of competitors. A series of super dramas made Youku win nearly half of the drama market in the summer file. According to statistics from Bida Consulting, Youku accounted for six of the top ten traffic dramas in Q3. Among them, "White Night Chasing Murder" became the most popular drama series in the third quarter with Douban score of 9.1.

After the verification of the summer file, Youku further pointed out the definition of super drama production: influential IP, appealing main creation and movie-level production, and the production standard of super drama must meet at least one of these three points. At the same time, Youku has redefined the drama series and divided it into super drama series, prime-time drama series and online drama series. Among them, "three are different", the audit standards are the same, and the target users, broadcast media and business models are different.

It was further confirmed at this autumn gathering that there will be sequels to the Alliance of Military Strategists, Spring Breeze is not as good as you in ten miles, and Chasing the Murder in White Night, which have created high reputation and high broadcast volume before. Yang Weidong, president of Dayouku Business Group, believes that the "sequels" of these super series are exploring the "Chinese-style seasonal drama" mode.

"Chinese-style seasonal dramas will not copy the American drama model or the Korean drama model, but will form China’s own standard of seasonal dramas." Yang Weidong said in an interview that in the future, China’s seasonal dramas will mainly focus on super dramas and online dramas. However, in Yang Weidong’s view, "the 12-episode seasonal drama is not suitable for the China market, which is determined by the viewing habits and business model of China users. In the future, the length of the seasonal drama in China will be dominated by 24+/36+/48+episodes per season."

According to titanium media, Youku will focus on supporting local seasonal dramas in China and promote the emergence of excellent domestic seasonal dramas with international competitiveness.The exploration of the seasonal drama mode needs to be based on the long-term and stable cooperative relationship between the platform and the content side.

"Today, the platform and the content side have changed from a short-term and simple production-purchase relationship to a long-term and closer symbiotic relationship. If the relationship between the content side and the platform is set to a simple one-shot sale, such content side has no future. " Yang Weidong said.

However, in the variety market, Youku’s own "cute baby+cute pet" "Little Hand Holding a Puppy" is still far behind iQiyi’s "Hip Hop in China" and Tencent’s tucao talk show "Tucao Conference" in terms of sound volume. In an interview with media including Titanium Media, Yang Weidong admitted that there was not much problem with Youku’s variety strategy in the past year, but it was "a bit conservative in tactics".In the coming year, Youku will put more energy into variety shows under the background that the series has achieved good staged results.

From the perspective of variety content market, the overall growth cycle of variety is 8-mdash; 10 months, compared with the drama, the life cycle is shorter, and it is more relevant to the market. This also directly determines that Youku’s two key words in variety tactics are "fast" and "content innovation", and the latter will innovate the content of the network around "new hearing, new stories and new knowledge".

At the autumn gathering, a series of web synthesizers were launched in one breath, covering comedy, dance, technology and other categories — — Will the coverage of such a "wide net" route by large categories cause insufficient focus on the content?

For this question, Yang Weidong said:"The Internet is a trial and error. If it is wrong, it will choose another program direction, but in general, it can’t be conservative, which will immediately reflect that the overall variety content rhythm of the platform will become very fast."

The Development Model of Secret Stories of Xihekou

In addition to self-made dramas and variety content, Ali literature, as the source library of IP, has not performed well in business performance. However, at this conference, Ali Literature made clear the key points of the next step.

First of all, Ali Literature officially released the IP "Xinghehui", announcing that its 60 boutique web IP will be fully open to entertainment industry partners, pointing to Tencent’s reading.

Ali’s open web IP covers popular categories such as city, history, romance, Xian Xia and suspense — — This is more than nearly 40 works published by the IP conference in early October.However, in terms of IP quality and reserves, Ali Literature is still a "late" player. In the future, how to find a differentiated breakthrough has naturally become the top priority of Ali Literature.

In addition, Ali literature is also trying to innovate in the development mode of online texts, from "IP development" to "all-round cultivation of IP".

Secondly, Ali literature pursues the cultivation in different stages, starting from the planning stage of IP. In other words, "Ali literature needs to achieve what purpose and reach what people, and needs to have some goals and carry out practical operations." Zhou Yun, editor-in-chief of Ali Literature, told Titanium Media.

In April this year, Ali Literature, together with Youku and Alibaba Pictures, invested 1 billion resources to launch the "HAO Plan". At present, the first step of the HAO project, The Secret Story of Hexi Kou, is being shown in Youku, which is based on the novel of the same name in Ali literature.

Taking "The Secret Story of Hexi Kou" as an example, Zhou Yun, editor-in-chief of Ali Literature, introduced to the titanium media, "This film was originally signed as a short story, not a long web text in the traditional sense. However, it will be cultivated in the subsequent operation. A little bit of web text; Then consider cultivating it in the general direction of the network. "

Another Line of Ali Literature — — After all, this mode runs faster than the IP of film and television dramas. Among them, the comic adaptation "Miao shou Xiao Cun Doctor" has achieved 2 billion hits on the whole network.

It is worth noting that today, when major video platforms consider literature and comics separately, Ali Literature insists on considering literature and comics together. Ali Literature itself has its own comic content operation position and a special operation team.

"Today, there are only three or four online literature companies in China, including Tencent and Ali Literature. Ali literature has developed for five or six years. Relying on the development of UC, the scale of writers has actually developed and accumulated for many years, from business scale to content cooperation. " Yu Yongfu told the editor of titanium media.

Yu Yongfu also said, "(net text) is not selling copyright. You must have a fixed literature user to cultivate literature and then seek cross-industry development. The linkage between literature and animation, drama series and games is cross-industry, which requires a solid business foundation of literature itself. In the category that Ali Literature is good at, the growth rate is faster than that of friends. In the end, each platform has different advantages in different categories. "

Then how to rely on Alibaba’s entertainment resources for IP commercial development? Zhou Yun, editor-in-chief of Ali Literature, told the editor of Titanium Media: "The TV series" in the name of people "exploded, which made the sales subscriptions of physical books and e-books on platforms including Ali Literature very high. This also shows that readers’ willingness or ability to consume has achieved initial results through the cultivation of the market. Everyone is not short of this money. As long as it is good content, many people are willing to pay. This is the basis for Ali Literature’s follow-up film and text linkage. "

To the sky kingdom, which has received much attention before, earned 300 million yuan by authorizing Bao and Taoxi merchants to develop derivatives, and will also provide a new idea of realizing IP for Ali literature and the whole content of Ali entertainment ecology.

Interestingly, in this Youku Autumn episode, the S-class variety show "This! It is street dance, TV series Beijing Women’s Picture Book and Shanghai Women’s Picture Book, all of which have the participation of Tmall Studio and are closely linked with e-commerce. In this regard, Yu Yongfu said that one of the two things that have the most Ali flavor and characteristics in Ali’s entertainment is how to turn Ali’s 500 million active buyers into our paid members.

The second is how to make content and business have a chemical reaction. Tmall Studio is Ali’s latest attempt, and attempts in this regard will only get faster and faster in the future. In the whole video war in the second half, the competition mode is undoubtedly the key point.

Regarding the future development of Youku, Yu Yongfu said: "When Ali didn’t have Youku two years ago, Youku was bought at any cost, but today’s considerations are different. First, we should fully develop Youku, and there is no upper limit for investment. What is the upper limit of impact input? But if Alibaba’s e-commerce encounters challenges in its operation, it is estimated that there will be conflicts. If there are no challenges, Ali will be very determined to think and invest in new business in the future.

"Teacher Ma Yun has a classic sentence, and I don’t think I can do it either. He saw it because he believed it. Most people believe because they see it. "Yu Yongfu said.(This article is the first titanium media, reporter/Zhu Taowei)

Creative poster | "Let more cultural relics and heritage come alive"

The General Secretary of the Supreme Leader attaches great importance to the protection of cultural and natural heritage and pays attention to protecting the roots of Chinese civilization. Since the 18th National Congress of the Communist Party of China, the general secretary’s "cultural footprint" has spread all over the country, and his "cultural entrustment" has a profound meaning and is thought-provoking.

The text is contained in the marrow of things and families. These lovely cultural relics "expression packs" contain the era significance of cultural inheritance emphasized by the general secretary. June 10th is the Cultural and Natural Heritage Day. Let’s look at the cultural relics in a different way. Through these lovely cultural relics "expression packs", we can understand the significance of inheriting and carrying forward the excellent Chinese traditional culture emphasized by the General Secretary.

More cultural relics:

He Zun, a bronze ritual vessel of the Western Zhou Dynasty (1046 BC-771 BC) containing wine. There are 12 lines and 122 ancient Chinese characters engraved on the internal pedestal, which records the conversation between two teenagers about how to make the country prosperous and inherit the glory of their parents 3000 years ago. Among them, "Zhai Zi China, Zi Zi Wa Min" is the earliest source of the Chinese character combination "China".

More cultural relics:

The bronze drum is made of copper, with a bottomless surface and a thin hollow wall. It first evolved from the copper kettle for cooking. This bronze drum with Xiang Lu pattern has a diameter of nearly 60 cm and weighs 30.75 kg, which shows that the owner of the bronze drum has an unusual status. In addition to being "big and heavy", the bronze drum with Xianglu pattern is also the most exquisite of all the bronze drums that have survived in the world.

More cultural relics:

This lamp came from the Western Han Dynasty (202 BC-8 AD), and it was named Changxin Palace Lantern because its body was engraved with the inscription "Always believing in bathing". Changxin Palace Lantern is ingenious in design, and it is the only bronze lamp in the Han Dynasty. The whole lamp is divided into six parts, each of which can be easily disassembled and reassembled. The sleeves of the ladies-in-waiting are connected with their bodies to form a smoke exhaust passage. The environmental protection design concept is unique and advanced, and it is known as the "Yi Deng in China".

More cultural relics:

This bronze mirror belongs to the Eastern Han Dynasty (A.D. 25-A.D. 220), which records the historical facts of Zhaojun’s departure from the fortress, and proves in kind that the story of Zhaojun and his relatives has been widely circulated in the Eastern Han Dynasty. What’s more commendable is that the inscription on the bronze mirror reads "Go to China to deal with the conference semifinals" and "Don’t use China for the military revolution", and the words "China" appear twice. This is the earliest known physical evidence that clearly compares the Central Plains Dynasty with the extraterritorial regime and calls itself "China".

More cultural relics:

In 1997, this female figurine, which is recognized as the most beautiful, was unearthed in Zhou Ying’s tomb in the Eastern Burial Cemetery of Hanyang Mausoleum in Xianyang City, Shaanxi Province. It is the most complete, elegant, exquisite and beautiful piece of cultural relics representing the image of women in the Han Dynasty in China.

More cultural relics:

The four sheep square statue is magnificent in shape and ingenious in design, with one sheep in each corner, and a pair of horned dragons in the middle of each side, with exquisite patterns and smooth lines. The statue adopts the decorative technique of combining round carving with relief, and skillfully combines the four sheep with the body, which embodies the original sheep totem worship. The whole object was cast by block method in one go, which showed a superb casting level and was called "the ultimate bronze model" by historians.

More cultural relics:

This cultural relic is called "Five-Pillar Ware of Moire Copper", dated to the Western Zhou Dynasty (1046-771 BC), and its use remains to be tested. Some people thought it was a musical instrument in the early years, but this view was quickly denied. Later, some people thought it was the base of something, but it was also vague. Others think that it is the base of the ancestral tablet when the ancients sacrificed their ancestors. This view also needs to be demonstrated in academic circles.

More cultural relics:

According to the existing statistics, there are 57 bronze figures with different styles unearthed in the No.1 and No.2 pits of Sanxingdui, only 4 of which are covered with gold masks, and this one is the best preserved one among the bronze figures unearthed in Sanxingdui. The gold mask is as thin as a cicada’s wing, with a thickness of only 0.2mm.. In ancient Shu, gold was revered, and putting a gold mask on the head of a bronze figure was closely related to religious customs, and it was also a symbol of its noble and authoritative status.

More cultural relics:

This carp statue is the first three-dimensional carp bronze found in China. It is fat but well-proportioned, the scales carved by thin lines are arranged neatly, and there are four "Hercules" under it who hold their bellies with both hands as weight-bearing. This cultural relic is a wine container on the dinner table of the Western Zhou Dynasty. The wine can be poured from the rectangular mouth on the back and then poured out from the open fish mouth.

The Central Meteorological Observatory issued a blue warning of cold wave, strong cooling, strong winds and dust.

  Cctv newsThe Central Meteorological Observatory issued a blue warning of cold wave on the morning of March 10th. Due to the influence of cold wave, it is estimated that the temperature in most areas of central and eastern China will drop by 6 ~ 10℃ from 10th to 12th, and the temperature in Inner Mongolia, North China, Huanghuai and eastern Jianghuai will drop by 12℃, partially exceeding 16℃. There are 4 ~ 6 winds and 7 ~ 9 gusts in the above areas, and 6 ~ 8 winds and 9~11 gusts in most offshore areas of China.

  The live monitoring shows that the temperature in North China and Huanghuai has risen rapidly in the daytime recently. Yesterday, the highest temperature in Shahe, Hebei Province reached 32.1℃, ranking first in the national meteorological observatory. At the same time, Zhengzhou (30.8℃) and Shijiazhuang (30.3℃) are also the first northern capital cities to break through 30℃ this year.

  Meteorologists reminded that before the arrival of the cold wave, the effect of "warming before the front" in the central and eastern regions was very obvious. Today, during the day, the temperature in some areas of Hebei, Shandong and Henan may still exceed the 30 C mark, but with the arrival of the weekend, the strong cooling will quickly cover most areas north of South China, especially the maximum temperature will drop sharply; The lowest temperature in this cold wave occurred on the morning of 13th, and the lowest temperature line of 0℃ will be located in the south of Shaanxi, the west of Henan, the south of Hebei and Tianjin, and the lowest temperature in the east of Shandong and the northeast of Jiangsu will also reach about 0℃. Please ask the public to add clothes in time and take good measures to prevent cold and keep warm.

  In addition to strong winds and cooling, there will be dusty weather in the northwest and north China today and tomorrow. The Central Meteorological Observatory continued to issue a blue warning of sandstorms on the morning of the 10th. Today, from day to night, some areas in eastern and southern Xinjiang, western Gansu, most of Inner Mongolia, Ningxia, north-central Shaanxi, Shanxi, north-central Hebei, Beijing and other places have sand or floating dust weather, and some areas in central Inner Mongolia have sandstorms.

  In addition, there will be obvious snowfall and local blizzard in the northwest of Heilongjiang and northeast of Inner Mongolia; There is rainy weather in most parts of the south, and the cumulative rainfall in some parts of the south of the Yangtze River can exceed 50 mm. Please pay close attention to the weather forecast and early warning information released by the local meteorological department, and pay attention to prevent the adverse effects of slippery roads and icing caused by rain and snow on traffic.

The best age for HPV vaccination is 9 to 14 years old.

  Cervical cancer is one of the common gynecological cancers and one of the few cancers that can be prevented by vaccine. Experts suggest that the incidence of cervical cancer in China tends to be younger, but the women who are willing to vaccinate HPV (human papillomavirus) vaccine are generally older. It is suggested that more attention should be paid to the vaccination of young women.

  Bi Hui, the chief physician of the Department of Obstetrics and Gynecology of Peking University First Hospital, found that most of the outpatients who came to consult about HPV vaccination were women over 25 years old, and teenagers aged 13 to 18 only occasionally saw them, and few parents brought their daughters to consult about HPV vaccination.

  Bi Wei said: "In China, bivalent and tetravalent HPV vaccines are currently approved for women aged 9 to 45, and nine-valent HPV vaccines are suitable for women aged 16 to 26. HPV vaccine has the best effect before sexual life, and teenagers should be the key population. The best vaccination age recommended by the World Health Organization is 9 to 14 years old. Our country’s guide recommends 13 to 15 years old as the key population. "

  According to reports, viruses such as HPV are divided into multiple subtypes, which can be classified into high-risk and low-risk types. High-risk type can cause cervical cancer, anal cancer, oropharyngeal cancer, etc. Low-risk type can cause flat wart, common wart and condyloma acuminatum on the skin. The main route of transmission of high-risk HPV is sexual transmission.

  Bi Wei introduced that in recent years, a study of more than 130,000 gynecological outpatients in eight tertiary hospitals across the country showed that the infection rate of high-risk HPV was nearly one-fifth.

  Studies have shown that bivalent and tetravalent HPV vaccines can prevent about 70% of cervical cancer and nine-valent vaccines can prevent about 90% of cervical cancer due to the different number of preventable virus subtypes. Experts emphasize that vaccination can greatly reduce the risk of cervical cancer.

Ten Common Faults of "Collection" Automobile Gearbox and Their Causes Analysis

The gearbox of a car, like the engine, is an oversized part of the car, and the cost can account for 15-30% of the whole car price. Generally, there will be no fault in the gearbox, but a fault is a big trouble. Today, we selected ten common faults of automobile gearbox and analyzed them one by one to share with you.

Common fault 1: oil leakage

Fault analysis:There is oil oozing from the gearbox housing or oil pan, one reason is that the seal is aging and the seal is poor; Another reason is that the shell has trachoma caused by poor manufacturing process.

Common faults 2: delayed entry, impact and engine flameout.

Fault analysis:The normal standard for entering the gear is to feel entering the gear within 1-1.2 seconds. When the brake pedal is released, the vehicle will slowly start without stepping on the accelerator pedal and gradually extract the speed of 10-20km/h..

If it is more than 2 seconds after entering the file, locate the delay of entering the file. This situation needs immediate repair.

If there is a strong impact feeling when entering the gear, the impact will be positioned.It should be noted that any automatic gearbox has a certain degree of impact when it enters the gear.If there is no feeling at all, it means that there is an internal fault. However, this shock is unacceptable, and the causes of this fault phenomenon are very complicated, including many aspects except gearbox.

The situation of dead fire when entering the gear is that the engine will die when entering the gear. This problem is more obvious when the car is cold. This problem is caused by gearbox problems and other body systems.

Common fault 3: hang in D or R, and the engine is turned off.

Fault analysis:This failure may be caused by the damage of the locking solenoid valve or the card issue of the locking control valve.

After shifting into D or R gear and releasing the brake, the vehicle does not move. Or the car can travel a short distance after the cold car starts, but it can’t travel in the hot car state. This situation is mostly caused by the damage of input shaft or reverse clutch, or the damage of D/R brake. It may also be that the automatic gearbox is seriously leaking oil and is seriously short of oil. The connecting rod or cable between the shift lever and the rocker arm of the manual valve is loose, and the manual valve is kept in neutral or parking position.

Common fault 4: the oil inlet screen is blocked; The main oil circuit is seriously leaking; Oil pump damage

Fault analysis:The impact and impact of vehicle shifting during driving is also a common fault phenomenon of automatic gearbox, which may be caused by too dirty gearbox oil, resulting in stuck valve body.

Common fault 5: the gearbox slips and the acceleration is weak; Transmission water inlet

Fault analysis:When the car is running, there is the sound of engine idling during the acceleration of the gas valve, and the speed of the car does not increase, which makes the whole car feel weak. This phenomenon is mostly caused by the burning of the clutch plate. Water enters the gearbox due to external reasons, resulting in abnormal operation of the gearbox. This may be due to oil in the water tank or water entering from the gearbox vent cap.

Common fault six: abnormal sound

Fault analysis:Abnormal sound can be divided into many situations. (1) is the abnormal sound of the bearing. Generally, the abnormal sound of the bearing is closely related to the rotational speed. The higher the rotational speed, the more screams there are.

(2) is the differential or main transmission gear abnormal sound, this kind of abnormal sound generally appears in the speed of 50-70 km is more obvious, because the meshing surface of the gear is not

Similarly, when refueling, the noise is obvious, and the noise of releasing the throttle is obviously weakened.

(3) is the abnormal sound of hydraulic system such as oil pump, which is closely related to the speed, but has nothing to do with the speed. When the speed is high, the oil pump is blocked to suck oil, which leads to screaming. It should be noted that the gearbox system works together with the bow | engine, chassis and other parts, and many sounds are mixed together, so it is not easy to identify it.

Common Fault 7: Odor in the box

Fault analysis:The gearbox works by hydraulic oil. When the oil temperature is too high, it will produce some combustion, and these peculiar smells will come out, which shows that some executive parts in the gearbox are not working properly.

Common fault 8: Automatic shift time is too long or too short.

Fault analysis:Generally, automatic gearboxes have a specific shift speed and speed. If it is found that the shift time is suddenly too long or too short, it means that the transmission ratio of the gearbox is out of proportion, and at the same time, it will feel that the engine speed is too high. What’s more, the gearbox does not shift gears, which indicates that there is something wrong with the gearbox.

Common fault 9: high engine speed while driving

Fault analysis:This problem is divided into two situations: high speed during steady driving and high speed during speed increase.

The high rotating speed during the steady process is caused by the failure of the high gear of the gearbox or the failure of the internal locking clutch of the button changer, so the gearbox needs to be repaired immediately.

The excessive speed in the speed-up process is controlled by the fuzzy logic of the electronic control system of the gearbox, so this standard needs a certain professional level to be completed.

Common fault 10: Engine idling

Fault analysis:Engine idling generally occurs in two situations.

First, when the vehicle is in a steady state, the bow and engine suddenly idling, and then it returns to normal when the speed slows down.

This situation generally shows that the gearbox suddenly drops from high gear to low gear in a short time, and the problem may be in the control system or cooling system, but there is nothing wrong with the gearbox itself.

Second, there is a short-term slip and idling phenomenon during acceleration or gear shifting.

The intuitive feeling is that the second one is not as powerful as the first one. In fact, it is just the opposite. Most of the problems of the second one lie in the clutch and other related links in the gearbox. It takes a lot more time and cost to deal with the complete disintegration and overhaul of the gearbox.

Sixty years of hanyu pinyin: approaching you and me and going to the world.

  Pinyin typing, consulting dictionaries, learning Mandarin … Today, Chinese Pinyin has been integrated into all aspects of our lives, so that it is often overlooked that it is not ancient, but the product of China’s language modernization and the crystallization of the wisdom of several generations.

  On May 10th, a symposium was held in Beijing to commemorate the 60th anniversary of the promulgation of the Chinese Pinyin Scheme. More than 100 representatives from education, scientific research, culture and other sectors discussed the historical experience and value of the times in the development, popularization and application of Chinese Pinyin.

  1. From word of mouth to scientific programs

  Why should we develop and promulgate the Chinese Pinyin Scheme? According to Wu Benyuan, the grandson of Wu Yuzhang, then director of the China Language Reform Commission, "In fact, the original purpose was very simple, that is, to use a good method to eliminate illiteracy."

  In the early days of the founding of New China, China’s illiteracy rate reached 80%. In order to quickly change its backwardness and pay special attention to literacy and cultural popularization, the CPC Central Committee carried out three major tasks: simplifying Chinese characters, popularizing Putonghua and formulating a scheme to promote Chinese Pinyin.

  At that time, the traditional pronunciation method and backcutting method in China showed obvious disadvantages in phonetic notation of Chinese characters. "Homophones should be used for straight sounds, while some syllables have no homophones, such as’ playing, brewing, and being timid’; Although some syllables have homophones, they are very uncommon. Note the sound is equal to no note. For example, the homophones of’ 司司’ have’ 司’ and’ 司’. Backcutting is to spell out a syllable with two Chinese characters for phonetic notation, such as’ one, it is difficult to master.’ " Su Peicheng, a professor of Chinese Department in Peking University, told the reporter, "You can’t use Chinese phonetic notation to learn Mandarin, because people who study like that can’t learn Mandarin if they read it according to dialect pronunciation."

  The ancient ones don’t work, but what about the designs made by foreigners? Since the end of Ming Dynasty and the beginning of Qing Dynasty, the phonetic notation methods designed by foreigners for preaching and learning Chinese include Matteo Ricci’s Latin alphabet, British Wittoma pinyin and American Kennedy’s Yale pinyin. "These pinyin schemes are all for foreigners, and there is neither a unified phonetic standard nor the pursuit of accuracy corresponding to the pronunciation of Chinese characters." Yuan Zhongrui, executive director of Chinese Language Modernization Society, said that we need to create Chinese’s own more scientific and accurate scheme.

  In fact, Chinese’s self-created pinyin scheme can be traced back to "At a glance" published by Lu Taizhang in 1892, and many schemes have been born since then, among which Wang Zhao’s mandarin letters, Wu Zhihui’s phonetic alphabet, li jinxi Zhao Yuanren’s national language Roman characters (Guoluo) and Qu Qiubai Wu Yuzhang’s northern Latin new characters (Beila) have the greatest influence. However, these schemes can’t meet the demand because they are not convenient for international communication or are not precise, simple and accurate.

  In 1955, the Central Committee instructed the China Character Reform Commission to study and formulate new Chinese phonetic alphabet tools. After three years of research and development, the National People’s Congress passed and promulgated the "Chinese Pinyin Scheme" on February 11th, 1958, and it was quickly popularized throughout the country.

  Following the "book with the same language", China culture ended thousands of years of oral history and started the era of "homophony".

  2. From literacy tools to cultural bridges

  "The main purpose of the Chinese Pinyin Scheme is to phonetic Chinese characters and spell Mandarin to help literacy, unify pronunciation and teach Mandarin. The purpose is to facilitate the people to learn and use Chinese characters and promote the further unification of Chinese, and it is not used to replace Chinese characters." On February 3rd, 1958, Wu Yuzhang clearly explained the two major functions of Chinese Pinyin-phonetic notation and spelling.

  Over the past 60 years, China’s illiteracy rate has dropped from 80% at the beginning of the founding of New China to 4.08%, the popularization rate of Putonghua has increased to over 70%, and the proportion of literate people using standardized Chinese characters has exceeded 95%, all thanks to Chinese Pinyin.

  Besides, designing special languages such as sign language and Braille, improving and creating minority languages, arranging all kinds of dictionaries, books, files, medical records, documents and other materials, and forming terms and codes … After 60 years of development, the function of Chinese Pinyin has gone far beyond the original idea and has become an indispensable and important tool. Zhang Wei, secretary of the Party Committee and president of China Braille Publishing House, said: "Chinese Pinyin is an important foundation for compiling sign language and Braille, which provides convenience for disabled people to fully participate in social life on an equal footing and share the development achievements of social civilization."

  Especially after the 1990s, with the advent of the era of globalization, informationization and intelligence, Chinese Pinyin has become an important tool for Chinese characters to input information by using international computer keyboards because of its colloquial, phonemic and Latin features, which has made ancient Chinese characters take the information express train to the world.

  With the development of the Belt and Road Initiative, Chinese Pinyin is more widely used in teaching Chinese as a foreign language. "Because of the particularity of ideographic characters of Chinese characters, foreigners can’t get the pronunciation from the glyphs of Chinese characters, so in the primary stage, pinyin is generally adopted to help Chinese beginners get started quickly." Zhao Guocheng, deputy director of Hanban, told reporters that Chinese Pinyin has become an important basis for teachers of Chinese as a foreign language to train students in pronunciation, rhyme and intonation.

  This is just as Zhou Youguang, a famous linguist and one of the main founders of the Chinese Pinyin Scheme, pointed out when Chinese Pinyin was implemented for 50 years: "In the past 50 years, the application of Chinese Pinyin has expanded at an alarming rate. Originally mainly used in the field of education, it is now significantly used in the field of industry and commerce. Originally, it was mainly a literacy tool for primary schools, but now it has been widely developed as a medium for information transmission. It turned out to be the key to domestic culture, and now it extends to an international cultural bridge. "

  3. From national standards to international standards

  “The city of Beijing!” On July 13th, 2001, Samaranch, then president of the International Olympic Committee, announced that Beijing would be the host city of the 2008 Olympic Games. The spelling of "Beijing" in Chinese Pinyin has replaced the Weitoma Pinyin "Peking" commonly used in the international community in the past. This subtle change has witnessed the course of Chinese Pinyin from foreign schemes to domestic schemes, from national forms to international forms, from internal and external differences to internal and external consistency, and from national standards to international standards.

  As early as 1977, the United Nations Conference on the Standardization of Geographical Names decided to adopt the Chinese Pinyin Scheme as the international standard for spelling Chinese geographical names in China, which became the first step for Chinese Pinyin to go global.

  Two years later, China, on behalf of Zhou Youguang, proposed to the Technical Committee for Standardization of Information and Documentation, an international organization for standardization, that the Chinese Pinyin Scheme should be taken as an international standard. In 1982, ISO 7098 Document Work-Chinese Roman Alphabet Spelling officially became the international standard of Chinese Roman Alphabet Spelling. This indicates that Chinese Pinyin has become an international standard from the national standard in China.

  However, for a long time after that, the actual situation of Chinese Roman alphabet spelling in the world was still multi-scheme, and at the same time, Chinese Pinyin Scheme, wade Style and Yale Pinyin coexisted, and many countries and fields still acted according to their own habits. Considering this actual situation and the new requirements for Chinese Pinyin at home and abroad in the information age, it is necessary to revise the previous scheme.

  Since 2011, China has officially started the revision of ISO 7098, and in June 2015, it was unanimously approved by the Technical Committee of Information and Literature Standardization, an international organization for standardization. Feng Zhiwei, the leader of the revision working group and a researcher at the Institute of Language and Character Application of the Ministry of Education, told the reporter: "The publication of this new international standard will help to improve the level of document automation in a digital and intelligent environment, so that Chinese Pinyin can play a greater role in international document work and further promote Chinese Pinyin to the world." Li Yuming, a well-known linguist in China, commented that this updated international standard "is a new step for Chinese Pinyin to enter the world, and also a new international step for Chinese culture".

Read the article: What is AI Agent after all?

The second half of the big model welcomes the CAMBRIAN Agent explosion.

540 million to 360 million years ago, marine life broke, and higher-level intelligence such as trilobites, sponges and chordates was born compared with previous single-celled or simple multicellular organisms. Similar to the CAMBRIAN explosion of life, experimental products such as BabyGPT, AutoGPT and Generative Agents have come out one after another.

From the perspective of evolution, the development of life is mainly realized by unit enhancement and organization enhancement. These two ways of enhancement complement each other, making life have more diverse and complex expressions.

Just like agent-we hope it is an agent that can think independently and interact with the environment in any system.

Now that it has a "brain" with enough IQ, how to make Agent think and execute like a human being-as long as any goal is given, it can automatically solve various problems. It is a "self" unit to further improve IQ and enhance agents; Or strengthen the "organizational" ability with the help of external modules?

Although today’s Agent can’t complete the general task, it is also difficult to form a dynamic stable body like the socialized division of labor among multiple cells. However, the local modules of individual Agents, such as HuggingGPT, have demonstrated their ability to use tools, including the fact that Plug-in has become an important milestone in the actual landing. In the second half of the large model, it will be the moment when the agent landed in Cambrian.

Where is the landing bottleneck of Agent at this moment? Can it reach GM from dedicated? What will multimodal bring to Agent? How will the future pattern evolve?

Just like the first cell born on the earth, even though the current Agent can’t replace our role in practical work, everything comes from this first cell, which is the starting point of agent evolution.

Even if you are confused about the landing of Agent, you should continue to "emerge".

Because the success or failure of Agent will be the key to decide whether this GPT revolution is a new generation of industrial revolution.

The following will think in a structured way, and where will Agent go?

1. What exactly is AI Agent?


A few days ago, the AI Town with 25 agents was officially open source, and the "westworld" AI Town was built with it. The interaction between AI Agents will deduce the evolution process of the whole civilization.

Andrej Karpathy, co-founder of OpenAI, also shouted: "AI Agent represents a crazy future."

What is an Agent? The word Agent originated from the Latin word Agere, which means "to do".In the context of LLM, Agent can be understood as an agent that can independently understand, plan and make decisions and perform complex tasks.

Agent is not an upgraded version of ChatGPT. It not only tells you how to do it, but also helps you to do it. If CoPilot is the co-pilot, then the Agent is the main driver.

A simplified Agent decision-making process, using function expression:

Agent: p (perception)-—> P (planning)-> a (action)

Similar to the process of human "doing things", the core function of Agent can be summarized as a cycle of three steps:perception(Perception), planning(Planning)And action(Action).

perception(Perception)Refers to the ability of Agent to collect information from the environment and extract relevant knowledge from it, planning(Planning)Refers to the decision-making process and action made by Agent for a certain goal.(Action)Refers to actions based on environment and planning.

Among them, Policy is the core decision of Agent to make Action, and action is observed.(Observation)It becomes the premise and foundation of further Perception and forms an independent closed-loop learning process.

This process is like Marxism’s "theory of practice": "Understanding begins with practice, through which theoretical understanding is obtained, and then returns to practice." Agent also evolved in the integration of knowledge and practice.

A more complete Agent must fully interact with the environment, which includes two parts-one is the Agent part, and the other is the environment part.At this moment, Agent is like "human" in the physical world, and the physical world is the "external environment" of human beings.

As you can imagine, the process of human interaction with the external environment: based on our full perception of the world, we deduce its hidden state, and combine our own memory and knowledge understanding of the world to make Planning, decision-making and action; And actions will react to the environment, giving us new feedback, and human beings will combine the observation of feedback and then make decisions, so as to go back and forth.

The most intuitive formula:

Agent = LLM+Planning+Feedback+Tool use

Among them, in the process of Planning, in addition to the current state, there are also memories, experiences, some reflections and summaries of the past, as well as world knowledge.

Compared with today’s ChatGPT, it is actually not an Agent, but a universal world knowledge, that is, a knowledge source for Planning. It is not based on specific environmental conditions, nor is it based on Memory, Experience and Reflection.

Of course, ChatGPT can do logical reasoning and certain planning based on its own knowledge, and it can also add vector database to solve reasoning problems, and add Reflection to enrich the process. In this way, ChatGPT, an end-to-end black box, can be made more explicit-in fact, symbols are a very explicit system, and based on this, it can be directionally corrected and promoted.

For Feedback, Agent gets positive or trial-and-error feedback, phased results or rewards based on Action. There are many forms of Feedback. If ChatGPT chatting with us is regarded as an Agent, the reply we typed in the text box is a kind of Feedback, just a kind of Feedback in text form. At this time, we are an environment for ChatGPT. RLHF is also an environment, an extremely simple environment.

"Man is human because he can use tools."

As an Agent, agent can also extend its functions with the help of external tools, so that it can handle more complex tasks. For example, LLM uses weather API to obtain weather forecast information. If you don’t call external tools, Action and Feedback can also deal with the environment directly by learning Policy.

It can be seen that Agent is the key to truly release LLM’s potential actively. As the core of LLM, Agent provides subjective initiative for LLM.

How to land the LLM today? LLM is an IQ engine, and other peripheral tools can be used as Prompt. Will LLM be an end-to-end system in the future? If there are not enough tools around, will there be a more general adaptation framework?

Second, the bottleneck of Agent landing is because "IQ" is not enough?


Agent itself uses two parts of abilities, one is LLM as its "intelligence quotient" or "brain" part, the other is based on LLM, and it needs a controller outside to complete various Prompt, such as enhancing Memory through retrieval, getting Feedback from the environment, and how to do Reflection.

Agent needs both brain and external support.

Is LLM’s own "intelligence quotient" not enough or its external systematization not enough?

If the degree of external systematization is not enough, it will be a long-awaited problem. If it’s just a problem of insufficient IQ, when GPT-4 becomes GPT-5 and has a higher IQ, it can make up for the previous problems.

So what is the main bottleneck of Agent?

To truly understand the crux of this problem, we can make wrong attribution first.That is to say, in the actual mistakes, it is clearly attributed to LLM itself or Prompt in the wrong way.

For example, ask the voice assistant "What’s the weather like?" The question itself is ambiguous-where is the weather? What day’s the weather? What information do you want to know about the weather? None of these problems can be solved by LLM itself, and it needs to call an external tool system.

If it is only attributed to "IQ", LLM only needs to understand "what’s the weather like". If there is a specific context, such as "what’s the weather like in Shanghai next month", whether LLM can infer accurate information based on this is a question of "IQ"; But what tools to call and whether the parameters to execute are accurate are not attributed to "IQ".

3. Can a more general external framework of Agent be realized in the future?

Many people regard LLM as the implementation of Agent, which is too simple and rude. For example, after setting a goal for Agent and defining some basic constraints, we expect it to complete the whole process of self-planning, task decomposition, self-prompting, and even calling external tools and giving answers. However, LLM itself is not trained in this way, and it certainly does not have this ability, but this is not due to the "IQ" problem.

From the perspective of Agent landing, external logical framework is still needed.

Although there are many kinds of Agent at present, most of them are superficial and not universal enough. Even the simplest Agent application, voice assistant or intelligent outgoing call system, its complexity and how to introduce environmental Feedback have not been effectively solved.

Therefore, in addition to a more detailed analysis of the errors, one question we should study is: Besides LLM itself being universal enough, will a universal external logic framework be realized to solve the problem of Agent’s real landing?

If we can’t find a common external logical framework, then the so-called AGI revolution may be just a bubble, a huge bubble, which may not be essentially different from the previous generation NLP.

At present, the landing of Agent is not only a question of "intelligence quotient", but also a question of how to get from special to general by external tools-and this is a more important question.

4. How can Agent have a universal adaptive environment? Do you need a learnable environment model?

What will happen if LLM is put into a virtual world?

In the game My World, NVIDIA developed the latest method, Voyager, to light up the technology tree at a speed of 15.3 times, and at the same time, he obtained 3.3 times of unique items and 2.3 times of exploration scope. The reason is attributed to GPT-4′ s in-depth understanding of the rules of the game and rich knowledge reserve, which comes from the pre-training process rather than the subsequent reinforcement learning.

From this perspective, in the process of optimizing Agent, we should not only pay attention to Feedback, but also consider how the model perceives the environment. So what is the relationship between the general brain and the environmental model, and how to cooperate? How does Agent arrive at General from Private?

At present, there are few good and universal landing effects of Agent, and most of them solve specific problems in specific scenes-LLM is used as a general brain and designed into different roles through Prompt to complete special tasks, rather than universal applications.

One of the key problems, namely, Feedback, will become a major constraint factor in the implementation of Agent, which is particularly evident in Tool use. For some simple problems such as weather query, it is only necessary to design an appropriate Prompt, but for complex Tools applications, its success probability will be greatly reduced.

It is impossible to make an Agent with LLM simply and rudely.

On the one hand, this approach ignores the importance of Feedback, on the other hand, even if LLM gets Feedback, it may not fully understand all the environments or Feedback by virtue of its "IQ", and it is even more difficult to adjust its behavior based on this.

In order to successfully land the Agent, it is necessary to give the Agent a more general adaptive environment. One possible solution is to create a small model dedicated to understanding and adapting the environment, so as to interact with LLM.

Because of super brain’s "IQ" part-LLM(such as GPT-4)Because the scale is too large, it is difficult to retrain specific Agent, and the small model can adapt to environmental changes and train many times. In this scene, we can regard LLM as the brain, and the small model is like the cerebellum, which acts as the middle layer to deal with the environment Feedback and interact with GPT-4.

So, what will be the implementation path of Agent from private to general?

Assuming that Agent will eventually land in 100 different environments, can a framework model be abstracted to solve all external universality problems under the premise that even the simplest external application is difficult to realize at present?

It may be one of the ways to realize the universal Agent by making the Agent in a certain scene to the extreme-stable and robust enough, and then gradually turning it into a universal framework.

5. How important is multimodal in the development of Agent?


Now GPT-4 is to convert all the contents into text language, and then human beings will Prompt it. First of all, the transformation process may lose information or produce errors, which may lead to the deviation of the results.

The next version of GPT, if it can realize the super ability of multimodal understanding, will it alleviate the unreliability and information loss and deviation of today’s Agent to some extent? What will be the relationship between multimodal and Agent?

If LLM does not need to interact in the real world, but only performs a specific task in the virtual world, then multimodal may not be very helpful for completing the task. But if LLM needs to interact with the real world, then multimodal is undoubtedly very important.

Multimodal can only solve the problem of Agent’s perception, but not the problem of cognition.

In many cases, such as intelligent customer service scenarios, users may provide information in a variety of ways. Multimodal has good perceptual value, but it is still far from solving some core problems such as logic and reasoning.

Multimodal is an inevitable trend, the future big model must be a multimodal big model, and the future Agent must also be an Agent in a multimodal world.

When developing text-based agents, when the multi-modal watershed moment comes, do these agents continue to develop on the basis of the original text and further integrate multi-modal characteristics? Or do you need to completely change the original concept and architecture of developing Agent to adapt to the future multimodal world?

The development of Agent does not need to be completely reinvented, but once Agent has multi-modal ability, it will be completely different from the existing model. For example, the next generation version of GPT may contain some more powerful multimodal understanding functions such as images. We don’t have to rush to build such a model immediately, but we can also choose to call such a module first, that is, it is best to build the multimodal understanding function into the model.

After half a year, we will see the arrival of multi-modal large models. The arrival of multimodal Agent may be faster than we thought.

First of all, many large companies are developing multimodal in general by stockpiling arms. The accumulation of this quantitative change is very likely to lead to qualitative change, and actual products may be launched soon. Secondly, the Agent people expect is an assistant like human beings. He can not only talk, but also see, hear and feel. Theoretically, an excellent Agent should be able to realize multi-sensory and multi-modal interaction, and both Perception and Policy need multi-modal.

With the release of RT-2, a new visual language action model, VLA, has realized the ChatGPT of the entity robot by stuffing the multi-modal large model into the manipulator. ?

From the trend point of view, the future Agent must be multimodal. Multi-modality must be necessary for Agent to succeed.

In the aspect of multimodal interaction, Digital Man also provides a good example, which shows the advantages of calling external tools. When the big model calls digital people, because the images have been set in advance, we don’t have to worry that it will suddenly generate the image or voice of a political figure, even his illusion.

Although it is euphemistically called "generative AI", it is better to call external tools in its "generative" part to ensure its certainty and avoid the illusion of the big model.

For example, in multimodal interaction, if you want LLM to play Trump and directly generate a congratulatory video, it is likely to be risky. It is safer and more controllable if LLM only generates scripts and then calls the established digital human and sound interface to synthesize video.

6. Will multi-agent really succeed?

Now the Agent is still a caveman, but the interaction of more AI Agents will change everything.

In the Generative Agents experiment inspired by the simulated life game, each role is controlled by an AI Agent, and they live and interact in a sandbox environment, which fully embodies the process of turning feedback and environmental information into action and realizing the "socialization" of AI Agents.

In the process of planning and response, AI Agents will fully consider the relationship between each other and the observation and feedback of one Agent to another Agent to take the next step.

This interesting simulation has led to some dramatic social phenomena, such as the spread of "rumors" and relational memory. In the experiment, two AI Agents often continue their previous topics, hold Party, call friends and other social activities.

Obviously, the real landing of Agent must be based on the perception of environment, dynamic learning and continuous updating.

7. In what scene did Agent first land?

As early as February this year, some online education companies began to be active in the discussion of big models. "Our industry, if we don’t act again, will be the first to be subverted." When most companies haven’t felt the impact of the big model, people from a head online education company first make predictions and worries.

And which industries will be subverted by Agent first, and which industries will not be so fast?

The ability of large model is well known, but "IQ" is only a part of the landing of Agent. Even if OpenAI claims that AGI has come, it is difficult to make practical applications if you know nothing about the industry.

Just like a doctor at Stanford, if you don’t understand the industry and product attributes of a company, then the initial work will be very difficult. Therefore, we need to discuss more deeply which industries are more suitable for Agent landing.

For example, the online education industry that can be completely online and digital, especially during the past three years, many offline industries have been hit, while the online industry has developed rapidly because of the advantages of digitalization, and it will be subverted by Agent first. In contrast, robots or traditional industries are more difficult to be subverted in a short time.

At present, whether in China or the United States, a new consensus is gradually forming: firstly, Agent needs to call external tools, and secondly, the way to call tools is to output codes-LLM brain outputs an executable code, such as a semantic analyzer, which understands the meaning of each sentence, then converts it into a machine instruction, and then calls external tools to execute or generate answers.

Although the present form of Function Call needs to be improved, this way of calling tools is very necessary and the most thorough means to solve the illusion problem.

8. Will the future development pattern of Agent be a hundred flowers blossom or Winners take all?

In the future, the competition pattern of big models is becoming increasingly clear, and it is inevitable that several companies will dominate or be based on open source.

And in the next year or two, what will be the market structure of Agent, and will it form the same situation?

Because Agent can’t be universal, Agent is not a monopoly, but will form a very long tail supplier pattern. There will be many Agent in the market, each of which is operated by a different company.

Like the previous generation NLP, many AI companies provide intelligent customer service or automatic outbound service, but each company can only serve a few customers and cannot form scale effect. Based on the technical judgment of Agent today, it is not much different from the previous generation.

Although the semantic understanding of LLM is universal, the combination of Agent environment and domain we discussed before is not universal, which will lead to a very scattered market, and no stronger company will appear.

Of course, Agent is also divided into depth.(major)And shallowness(universal)Two types.

We want to be a general Agent. In the market environment of China, if an Agent is deeply integrated with the enterprise, it will eventually become "outsourcing" because it needs to be privatized and integrated into the enterprise workflow. Many companies will compete for big customers in insurance companies, banks and automobiles. This will be very similar to the outcome of the previous generation AI company, and the marginal cost is difficult to reduce, and it is not universal.

The future is the world of Agent. Under the Agent process today, the story of AI yesterday is still repeated, and the privatization deployment will face challenges.

No clothes, no robes: designing "barrier-free clothing" for the disabled

  "Try not to go out and drink water."

  It takes Wang Juan 20 minutes to an hour to get dressed once.

  As a paraplegic patient with cervical spinal cord injury, she has no consciousness below the clavicle, only her arms can move slightly. Dressing is the first topic every day among the many difficulties she has to face in life.

  After years of exploration, Wang Juan has developed a suit of dressing procedures.

  First of all, she needs someone to help her. This person is usually her mother. Every morning, Wang Juan lies flat on the bed, and her mother lifts her leg, first puts the foot cover into trouser legs, and then pulls the waistband up a little. Usually at the thigh, the pants can’t be pulled. Mother wants Wang Juan to lie on her side, lift her waist and thighs, and then continue to pull the pants until she can’t.

  Then the other leg, repeat the same process until the pants are completely put on.

  "It’s like a pancake that has been tossed from side to side." Wang Juan teased himself.

  Put on her pants and she can be moved to a wheelchair to put on her coat. The upper body is out of control, so she can only lie in her mother’s arms and keep her back hanging with her mother’s support, so that the clothes piled up at the shoulder and neck can be pulled down.

  There are few clothes in summer, and in winter, from thermal underwear to knee pads, you have to put them on your body layer by layer, so Wang Juan chooses to go out less.

  I have to bend down to dress my daughter. Wang Juan’s mother suffers from lumbar muscle strain. Although she has raised the bed and put on an auxiliary belt, she still needs to rest several times during dressing. Looking at all this in bed, Wang Juan couldn’t help thinking, "What should I do if my mother can’t take care of me one day?"? I want to go back to the original appearance and stay in bed? "

  There are more than 85 million disabled people in China. In recent years, their situation has attracted more and more public attention, and the construction of barrier-free facilities in public spaces has been improved. However, in private spaces, they still have many individual and specific needs, and dressing is one of them.

  For Li Feiyu, 24, dressing is no longer a problem. When she was 7 years old, she was paralyzed by acute myelitis, and for the next 17 years, she was accompanied by a wheelchair. The mother did not take care of her daughter as a weak person, but asked her to take care of herself as much as possible within her ability.

  Li Feiyu can’t remember the details of learning to dress as a child, leaving only the impression of "very hard and difficult". What she remembers deeply is a set of dressing movements that have been practiced. Li Feiyu feels that it is more difficult for many people who encounter disability difficulties in adulthood to learn to wear clothes than themselves.

  Li Feiyu works as a volunteer tutor in a public welfare project called "Life Reconstruction", teaching people to wear undresses in wheelchairs. I can’t talk about any skills. Most of the time, the tutor can only do it by himself. By repeatedly undressing, the students can follow suit.

  It is not difficult to learn the process and skills. After two or three days of classes, most students can master the basic skills. The hard part is that after that, they need to let their skills and limbs run in for a long time, and finally find the best dressing tips for them.

  Li Feiyu remembers a former weightlifter. After the girl was paralyzed by spinal cord injury, she became strongly dependent on her parents and relatives and refused to take care of herself. When she first entered the training camp, she called the nurse for help in everything. Li Feiyu patiently guided her and taught her how to dress independently. Pants can’t be lifted up, and girls used to think that they were not strong enough. "But she is a weightlifter. It can’t be a matter of strength. She just didn’t find the trick." Li Feiyu recalled.

  "This is a cognitive problem. Many disabled people think that I am sick, I can’t, and others have to help me. This concept is very dangerous. I hope disabled friends can have a more independent life." Wang Juan said.

  "Independence" is limited after all. For example, when going to the toilet, the reporter learned in the interview that many wheelchair users with lower limbs paralysis will try not to drink water when going out, because going to the toilet is very troublesome. They need to lift their bodies from the wheelchair with their arms, and then one person will help them to take off their pants. Because their lower limbs can’t stand, they can’t sit on the toilet in a normal posture like ordinary people. Someone needs to set them up and ride backwards on the toilet with the barrier-free handrail.

  In 2006, Wang Wenjuan, who taught in the Department of Fashion and Costume Design of Beijing University of Technology, went to Chaoyang District Disabled Persons’ Federation for investigation. A wheelchair user calmly showed her the whole process of going to the toilet, while the scholar cried.

  She thought, there is a surplus of fashion for the able-bodied and the disabled have never owned their own clothes in the real sense. "We should see more of the needs of these minorities."

  Real designers are not designers.

  The concept of "barrier-free design" was born in the architectural field at the beginning of the 20th century. The original intention of this concept is to create a "convenient, safe, equal and participatory" space for the disabled by using modern architectural design skills.

  At the beginning of this century, in China, few people tried to combine "barrier-free" with "clothing design". Therefore, when the design team of Beijing University of Technology began to do relevant research, everything seemed to "cross the river by feeling the stones".

  Wang Wenjuan recalled that she and her team members sought support from the Disabled Persons’ Federation and set up a research meeting. However, most people with disabilities are inconvenient to go out, so they go to other activities organized by the Disabled Persons’ Federation to conduct on-the-spot research while the participants are resting. In order to better understand the immediate needs of the disabled, they will try to reconstruct the scene, such as tying their arms with ropes to simulate armless people, or wearing protective gear to experience the feelings of hemiplegic patients.

  In such research, they found some real needs. For example, most armless people use their feet instead of their hands, so they need to consider adding more functional designs to their lower body clothes, "putting pockets on their legs"; The underarms of crutches bear pressure and friction for a long time, so it is necessary to consider increasing the wear resistance and breathability of the underarm fabric of their tops; Visually impaired people have higher requirements for shoes. When they walk, they usually need to "explore the road with their feet", and the wear rate of shoe tips is high.

  Different types of disabled people have different needs for clothing. Even people with similar disabled parts, individual differences in concept, symptoms and body shape make their demands for clothing different. These demands are hidden and complicated, which put forward very high requirements for the preliminary research work of the design team of Beijing University of Technology.

  "Wheelchair users" is the research focus of the design team of Beijing University of Technology. On the one hand, they have the most prominent clothing barriers, and on the other hand, people with physical disabilities are the largest in all disability categories, accounting for about 29%.

  For "wheelchair people", clothing design should not only realize the basic functions such as "putting on and taking off conveniently", but also pay attention to the needs of many details. For example, pants should be high-waisted, because they usually need to wear diapers to go out, and high-waisted pants can cover the upper edge of diapers; The crotch design needs to be wider than ordinary people’s pants, because wheelchair users sit for a long time all the year round, and the waist and buttocks are easy to accumulate fat; Cuffs are easy to wear because they often push wheelchairs, and at the same time, complicated design should be avoided to prevent them from being involved in wheelchairs; For men, ordinary belts and front crotch zippers may cause sedentary discomfort.

  "People with disabilities are eager for us to solve the problem. In fact, they didn’t have much idea about clothes before, thinking that clothes should be worn like this and they are used to it." Wang Wenjuan said.

  Before understanding the concept of "barrier-free clothing", Zhang Xiaoli was such a patient. At the age of 11, she was forced to sit in a wheelchair because of the severe kyphosis deformity of 180 degrees, which compressed her nerves and caused paralysis of her lower limbs.

  "I used to feel unconsciously that there were no clothes suitable for us. I couldn’t buy clothes and I couldn’t wear the confidence of ordinary people." Zhang Xiaoli recalled, "I have never worn a skirt beautifully, and it is my biggest dream to wear a dress properly."

  Twelve years later, 23-year-old Zhang Xiaoli finished spinal orthopedic surgery and put on a skirt. She cried happily, which also prompted her to think further: "Why are there no clothes specially made for the disabled?"

  In 2021, Zhang Xiaoli came across the enrollment brochure of Chengdu Textile College and came up with the idea of making clothes for the disabled. She applied for this school and began to study fashion design. With the support of her teachers, she established a design team of "barrier-free clothing".

  She named this project "23-degree Clothing Setting" because in her hometown of Aba Prefecture, Sichuan Province, 23 degrees Celsius is the most comfortable temperature, and she also learned that the most comfortable temperature that human body can feel is 23 degrees Celsius.

  "This is what I understand as barrier-free clothing. People with disabilities can find the most suitable and comfortable feeling by wearing such clothes." Zhang Xiaoli said.

  In Wang Wenjuan’s view, the core of "barrier-free clothing" is its functionality, and "solving problems is the first purpose". For example, she and her team designed the "barrier-free and convenient pants" for wheelchair users, and designed the pants as a piece of cloth-style fully open style. Instead of lying on the bed as before, they can be spread on the wheelchair, sit directly on it, and then zip the open cloth edge. At the same time, in order to solve the toilet problem of wheelchair users, this team has made a crotch design that can be opened and closed directly from behind, reducing the steps of wearing and taking off.

  Wang Wenjuan recalled that to design a barrier-free garment, it is necessary to know the actual needs of the disabled people through investigation and study, and make repeated measurements and communication during the design process to constantly confirm the specific situation of the wearer.

  "It’s not a one-off event, but an iterative process." Wang Wenjuan said, "So the real designers of barrier-free clothing are not the designers themselves, but those with disabilities. We just help them complete the design according to their needs."

  Put it on, not hide it.

  Zhang Peng, a professor at the Department of Fashion Design of Beijing University of Technology, pointed out that it is important to consider the functionality when designing barrier-free clothing, and at the same time, it is also necessary to consider the wearer’s acceptance in psychology and emotional dimension, and it is necessary to pay attention to both function and aesthetics.

  In the survey, the team found that when people with disabilities are asked about their demands on the appearance of clothes, their expression is often: "Please let me be like a normal person."

  "Being normal" is Ganshanna’s dream.

  Similar to Zhang Xiaoli, Ganshanna suffers from severe scoliosis. Looking from the back, her right waist is empty, while her left waist protrudes high, and the height difference between her shoulders is significant.

  When she was a child, Ganshanna never dared to think about her "favorite clothes" because she could only wear "suitable clothes". When mother and grandmother buy clothes for her, the first principle has always been "how to better cover up the physical abnormality".

  Ganshanna wears a lot of clothes that she doesn’t like, but she never asks, "because I think it’s good that I can have clothes to wear."

  She drew her longing on paper. The clothes she likes but can’t wear are quietly hidden in the album by her. "It seems that they belong to me after painting." She remembers that there was a beautiful girl in the class who had beautiful and inexhaustible clothes. Ganshanna was a little jealous, but more envious. "I want to be friends with her, and I want to be close to my ideal type."

  The reality is that Ganshanna’s fantasy is always broken by her classmates’ abuse of "monsters". She suppressed her desire for beautiful clothes. "I don’t think anything a little better suits me, so I can’t think about pursuing it anymore."

  Wang Juan and Ganshanna have similar mental processes.

  Recalling the days before the car accident at the age of 19, Wang Juan would talk about her fighting with friends, running, shopping and wearing high heels herself.

  There used to be many pairs of high heels in Wang Juan, with different materials, colors and heel heights … … Fill the shoe cabinet. Later, she got into a wheelchair and threw away all her high heels.

  She said that you don’t need many shoes in a wheelchair, because you don’t need to walk, and a pair of shoes can last for a long time. For her paralyzed lower limbs, a pair of shoes is far more important than "good-looking". Give her shoes, mother should squat down in front of her legs, try to loosen her knees, and then slowly put her feet into the shoes. There is always a toothbrush in the storage bag on the back of her wheelchair. When she can’t put on her shoes, her mother will use the toothbrush back to smooth the toes in the shoes.

  Wang Juan always wears those pairs of shoes that are convenient to put on and take off, and more importantly, "I don’t want to see my old high heels again."

  A few years before the accident, Wang Juan was lying in bed all day, counting the folds on the curtains, counting from left to right, and counting the concave surfaces before counting the convex surfaces. "That’s the only place my eyes can see except the ceiling.".

  At that time, she no longer had any expectations for life and the future.

  The turning point came in 2015. Teachers from the local Disabled Persons’ Federation Rehabilitation Center found Wang Juan and invited her to participate in a public welfare training camp for people with spinal cord injuries.

  "I don’t know how to describe it in words, but this training camp has such magic. You have found a group life similar to yours. When you see others’ self-confidence and cheerfulness, you will feel that I can change my life and live well."

  Wang Juan recalled that when he first entered the camp, many people didn’t wear shoes, or wore colorful thick-soled wool socks knitted by rural elders. She explained that these people are at home all the year round and have no need to go out, so they don’t need shoes; Or they want to continue the state at home, what it is like at home, and it is still the same outside.

  There is a boy with a head of hair that obviously collapses on one side. Wang Juan thinks of herself. She also has the same hairstyle when she is in bed all the year round. She used to love to wear clothes, go shopping and buy fashion. After paralysis, she wore a flower sleeping jacket all day. "I don’t think there is any problem with this. It seems that everyone agrees that this is what I should wear."

  When she arrived at the training camp, Wang Juan saw that some injured friends who were also in wheelchairs were dressed appropriately. After returning home, she asked her mother to take out one of her down jackets and didn’t want to go out in cotton pajamas. Mother’s first reaction was to refuse. She concluded that Wang Juan could not put on her old clothes, and most of them were given away or thrown away.

  At Wang Juan’s insistence, her mother helped her put on the down jacket. It was just a very ordinary and plain black down jacket, but she never forgot it.

  Wang Juan asked her mother why she felt that she couldn’t wear her old clothes. She remembered her mother mumbling, "I don’t know what to think, but I think you can’t wear your old clothes."

  After the training camp, at a party with injured friends, Wang Juan bought the first hairband after the injury. "You ask me why I want to buy it? I don’t know. But I saw it when I was shopping. At that moment, I saw myself through the mirror. I thought I was beautiful. I think I want to have it, I should have it, and I deserve it. "

  Ganshanna has also gained the sense of beauty and dignity brought by dress.

  When she was a freshman in high school, she bravely tried on a lavender "Lolita" dress under the recommendation of a friend. For her who has always had a strong sense of inferiority, it is a great challenge to try such a gorgeous dress style. Unexpectedly, she won the admiration of her classmates.

  This is the first time Ganshanna has gained confidence because of her appearance. After that, she tried different styles of dresses. With the support and encouragement of her friends, she gradually became indifferent to the negative comments.

  "People who praise me will shout it out louder." She said, "I feel that I also have the right to pursue beauty."

  When she was in college, Ganshanna heard of Zhang Xiaoli’s "23-degree dress-fixing" project in a fashion design competition, and "she felt stabbed in the heart at once". This is also the first time she has heard of "barrier-free clothing".

  After getting to know the Zhang Xiaoli team, Ganshanna has a "customized skirt". The "A-shaped" version well covers her distorted waistline due to scoliosis, and the bow that unfolds obliquely at the back visually adjusts her high and low shoulders.

  This dress also implies the blessing of Zhang Xiaoli team members to Ganshanna: "I hope she can change like a butterfly."

  The design is trapped in the drawings.

  When studying "barrier-free clothing" in 2006, the Department of Clothing and Clothing Design of Beijing University of Technology was still a "lonely pioneer". Nowadays, it has many "teammates", and many universities across the country have successively carried out research on "barrier-free clothing". However, until today, many design concepts are still trapped in drawings, and there are few real industrialized products.

  Some international clothing brands have also entered the field of design and production of barrier-free clothing. Tommy Hilfiger, an American casual clothing brand, designed jeans that can cover artificial limbs for people with disabilities; Nike, a sports brand, has developed a series of "GO FlyEase" sports shoes for the disabled. Some barrier-free fashion brands have emerged, such as Rebrith Garment and Tenbo. According to the report of Coherent Market Insights, an international data analysis organization, the global barrier-free clothing market is expected to reach 400 billion US dollars in 2026.

  Since 2017, several domestic enterprises have contacted the service team of Beijing University of Technology to discuss cooperation matters, including a well-known down jacket enterprise. Finally, after being evaluated by the marketing department, the brand gave up its investment and turned to overseas markets with more profitable space. There are also some venture capital companies that are more willing to speculate on concepts.

  "We hope to serve social groups, but corporate investors are more concerned about benefits." Wang Wenjuan helpless way. She understands the concerns of enterprises, and the research and development of "barrier-free clothing" is difficult and the production cost is high. Choosing "barrier-free clothing" means rebuilding the team and production line. "All design teams and technical teams … … The materials may be different from before, and the risks faced by enterprises are great.

  In addition, different from the garment design of healthy people, the individual status of disabled people is very different, and there is no "standard size" due to the lack of relevant measurement data, which makes it difficult to achieve assembly line mass production of garments and needs to be customized according to individual needs.

  "The ideal state is to be able to solve individuality from commonness." Wang Wenjuan said. But it also means greater investment in research and development.

  Wuhan textile University professor Yan Jun introduced that the overall size of foreign garment industry is small, with a long development time and a high degree of refinement. "They can have 11 sizes for a pair of trousers, and we may generally have only 4 sizes. Foreign garment enterprises are more accepting of the complexity of garment production."

  China’s clothing industry has the origin of cooperation with foreign trade enterprises after the reform and opening up, and it has the gene of mass production itself. Mass production is the consensus of many clothing enterprises, which will also affect the willingness of enterprises to invest in "barrier-free clothing".

  Compared with the high cost of original design, the cost of pirated clothing is low. According to Wang Wenjuan, in recent years, China has paid great attention to the protection of patent property rights, and the designers’ association has been studying the issue of clothing copyright, but clothing is too easy to be pirated. "You have worked hard, and if you put it into the market, it may be pirated immediately. You are helping them develop it at no cost."

  Even if we can go to the last stage of production, sales will be a big problem. There are more than 85 million disabled people in China. On May 15th this year, the China Disabled Persons’ Federation held a theme conference on the Day of Helping the Disabled, indicating that by the end of 2022, 10.455 million disabled people would be included in the minimum living guarantee. Most people with disabilities have low economic level and poor consumption power. The price of "barrier-free clothing" of foreign brands is thousands of yuan, which is difficult for them to afford.

  "The difficulties faced by barrier-free clothing are all aspects. It is a comprehensive and systematic problem. It is indeed valuable, but it is also difficult and needs to be promoted slowly." Wang Wenjuan concluded.

  Clothing is a symbol.

  Xu Jinze is a visually impaired person who has long been concerned about the protection of the rights and interests of disabled groups. In his view, the development dilemma of "barrier-free clothing" essentially reflects the general survival dilemma of disabled groups.

  He cited his visually impaired group as an example. On the surface, most visually impaired people’s dressing styles are very simple, simple and conservative. On the one hand, it is because of visual impairment that they limit their imagination of dressing. The deeper reason, he thinks, is that the visually impaired group "has a single living and growing environment, which leads to their single demand for beauty and clothing."

  He has been engaged in massage for the blind for a long time and is currently a partner of a chain massage brand. According to him, there are 17 million visually impaired people in China, and about 1.8 million people have formal jobs, and 90% of them are engaged in massage for the blind. On the other hand, most visually impaired people were educated in blind schools and grew up in a closed environment.

  "The environment in which we grow up, live and work defines our future, and clothing is just a representation under this definition. When we discuss clothing, we should pay attention to the humanistic factors and social problems behind it. "

  Compared with discussing "barrier-free clothing" from an industrial perspective, Xu Jinze believes that what this field needs more is actually a kind of "multi-integration" of society. The relationship between healthy people and disabled people should not be simply "seeing and being seen", but "accepting and being accepted". "We are all surrounded by a specific environment. It is not that you are unwilling to help us. It is that you can’t find our needs, and even we don’t know our own needs. We are separated."

  Xu Jinze mentioned that in Japan, visually impaired students can also study in normal public schools, and there will be teachers in charge of special education who will come to the school and class where the student is located to help him coach Braille and have barrier-free communication with his classmates. If this process continues from primary school to higher education, the student will naturally blend in with the surrounding environment, and after graduation, he will have the opportunity to engage in more kinds of jobs, without having to call for "getting to know each other" after he becomes an adult.

  Hu Wenbing, vice chairman of Wuhan Association for the Disabled, also stressed the importance of integrating the disabled into society.

  Hu Wenbing used to be an executive of a central enterprise. At the age of 37, he was disabled by a car accident. After the injury, he promoted the establishment of a "life reconstruction" public welfare training camp, aiming at helping the disabled to adjust their mentality, learn skills and reintegrate into normal society.

  Dressing teaching for wheelchair users is an important course of "Life Reconstruction" project, and Hu Wenbing is happy to see people’s concern about the dressing needs of disabled people.

  "Now it is no longer a society where people with disabilities are confined to their homes, especially those who are disabled the day after tomorrow. Many people have good academic qualifications and jobs before, if they can put on and take off their clothes and ‘ Erbian ’ If the problems are handled well, then they will have more opportunities to make their own careers in society. "

  In the training camp, Wang Juan saw many students regain their willingness to dress up in mutual support. Some people took off their knitted wool socks and put on fashionable snow boots, and began to pay attention to dressing decently and beautifully like healthy people.

  Wang Juan remembers that once, she and her friends were asked in the street where the wheelchair was rented. "I mistakenly think that we are healthy people who are too lazy to walk. It didn’t happen before. When others look at it, I think it is a disabled person or a patient. "

  Wang Juan also saw that a group of disabled people were rebuilding their lives with love and support. Clothing has become a symbol, expressing her and many disabled people’s demands and expectations to integrate into society. In her view, this expectation is nourished by the support and care of many parties in society, which is in line with the original intention of the birth of the "barrier-free concept".

  Although the development of "barrier-free clothing" still has a long way to go, the research team of the Department of Fashion and Fashion Design of Beijing University of Technology is still willing to remain optimistic. They said that in recent years, they have received more and more attention from multimedia, universities, enterprises and non-profit organizations. This concern itself represents the development trend of social concepts. At least in the field of fashion design, they hope that "barrier-free clothing" can convey an idea to students and the public:

  "Don’t be satisfied with your immediate needs, but pay more and more attention to others and society."
