　　Wu Guanghui, chief designer of Comac C919 and ARJ21, has won the national special prize for scientific and technological progress and the first prize for national defense scientific and technological achievements. A key model won the first prize of China Aviation Industry Corporation I and the first prize of the National Defense Science, Technology and Industry Committee.

　　"Many aircraft parts are made in China and fly in the sky every day. C919 has gone through nearly seven years, and has done a lot of design, calculation and experiments. I am definitely willing to take this plane first. "

　　— — Wu Guanghui

　　These days, in the commercial aircraft test center of China Commercial Aircraft Corporation, the newly-built Zhuqiao test hangar in Pudong is spacious and bright. In the hangar, the landing gear that originally supported the domestic large passenger plane C919 was all put into the landing gear cabin, and three air springs like "jacks" lifted the plane into mid-air. What is going on here is the ground resonance test and modal coupling test of the whole aircraft that must be completed before the first flight, which means that the C919 has officially entered the final sprint stage before the first flight.

　　C919 is a domestic large passenger plane independently designed and developed by China. It is a short-haul single-aisle narrow-body passenger plane with more than 150 seats. In the future, it will compete with internationally renowned commercial aircraft such as Airbus 320 series and Boeing 737 series for orders. The manufacturer China Commercial Aircraft Co., Ltd. recently announced that the C919 plans to make its first flight in the first half of 2017 and will fully launch the wide-body passenger aircraft project. It can be said that after nearly 10 years of hard work, China people’s dream of "big plane" will soon become a reality.

　　① Rigorous test to ensure safety.

　　To fly into the blue sky, a plane must first practice a pair of steel bars and iron bones. For the C919, which carries the dream of a big plane for Chinese people, the significance of the test is even more significant. This is the first large passenger plane made in China, and its safety cannot be lost.

　　For this reason, C919 has undergone a series of tests like "torture". Among them, the 2.5g static test of the whole aircraft started in early November last year is the most severe and significant one since the birth of the C919.

　　This test mainly tests the strain and deformation of the "skeleton" of the body under constant external loading. In layman’s terms, this kind of test is to let the aircraft simulate the stress situation when challenging air flight on the ground, and go beyond the natural limit to verify how much force the aircraft can bear.

　　Before the start of the experiment, the researchers covered the whole body with white adhesive tape, which is a resistance strain gauge that can sensitively measure stress and strain close to the surface of the body, just like doing electrocardiogram for the plane. During the test, the load starts to rise at the level of 5%, and the load must be kept for 3 seconds every time. "The structure must be able to withstand the ultimate load for 3 seconds without damage." Zhou Liang Dao, deputy chief designer of the C919 passenger plane, said that the preparation behind the team took more than 300 days for this short three seconds.

　　With the continuous loading, the aircraft began to show obvious external reflection, and the wing began to tilt up a little. Finally, when the load reaches 100% of the test outline, the wing tip tilts up to nearly 2 meters, which is highly consistent with the strength analysis before the test, which shows that the test is successful and its strong "bones" and body are enough to support flying into the blue sky.

　　This is just a small step in the long March before the first flight of the plane. A passenger plane has to complete 13 static tests in 48 working conditions, including pressurization in the booster cabin, front lifting connection, main lifting connection, whole aircraft condition, vertical tail and rudder, as well as "three-bird test" such as iron bird, copper bird and electric bird and joint test of the whole aircraft system. Therefore, researchers have made independent innovations in system integration experiments.

　　In the comprehensive test hall of Shanghai Aircraft Design and Research Institute, the iron bird test-bed with little difference from the C919 real machine looks like an eagle with wings spread and its tail stuck high. Don’t underestimate this test-bed. Its full name is "Integrated Test-bed for Flight Control Hydraulic System", which mainly tests the landing gear, wings and other mechanical systems of aircraft. In order to ensure the authenticity of the system test, the iron bird test-bed is designed according to the 1:1 ratio of the real aircraft, so that the mechanical installation interfaces of the flight control, hydraulic and landing gear systems are the same as those of the aircraft.

　　Next to the Iron Bird Test Bench, there is also a "Copper Bird" that tests power supply systems such as power generation and distribution, and also restores the real state of the machine to 1:1 for equipment installation. "Iron Bird", "Copper Bird" and the avionics system test called "Electric Bird" will eventually be all connected, thus forming a "three-bird joint test" to simulate the state of the aircraft.

　　In the experiment, researchers conducted a comprehensive test on the aircraft system. Take the avionics system as an example. At most, there are more than 100,000 parameters in a test. These parameters should be tested one by one to find out the possible omissions in the design. "Our goal is not to take the fault to the sky." Yu Shenghui, senior engineer of the General Aerodynamics Department of Shanghai Aircraft Design and Research Institute, said.

　　According to the plan, six testing machines are carrying out joint testing of the whole machine system, and customer service engineering and airworthiness work are also being carried out simultaneously.

　　②C919 is genuine China goods.

　　As the first large passenger plane with completely independent intellectual property rights in China, C919 has been frequently questioned since it was established in 2006: an aircraft whose engine, avionics core processing system and some materials all depend on foreign products or technologies, why should it be said to be "made in China"?

　　In fact, to evaluate the innovation of C919, we may need to draw lessons from a fairy tale named Pony Crossing the River. This story is about a pony crossing a river. A cow next to it said, "The water is very shallow, just without a calf, so you can cross it." But the squirrel in the tree said, "The water is deep and will drown." So, is the river deep or shallow? Finally, the pony got off the river by himself and carefully waded to the other side. It found that the river was neither as shallow as the cow said, nor as deep as the squirrel said. The same is true for the development and innovation of C919. Everyone should not only see the major innovations achieved in the process of aircraft development, but also objectively admit the existing shortcomings.

　　According to international standards, judging whether an airplane is made in China or assembled depends on whether it meets three conditions. 1. Who owns the property right of the whole machine? Second, who is the core team to develop the whole machine? Third, who holds the key link in the development of the whole machine? For C919, the answer to these three questions is China.

　　The person in charge of Comac in China said that the property right of the C919 is owned by Comac in China. The team of Comac in China is the core of the development, and the key links such as aircraft design, final assembly, test flight and sales are in the hands of Comac in China.

　　As for foreign companies providing parts or technology, this is a common thing in the global aviation manufacturing industry. Aviation manufacturing giants such as Boeing and Airbus also use foreign products on many key components when developing aircraft.

　　However, for equipment like engines, the C919 chose the LEAP-X1C engine jointly developed by the United States and France, which is the only foreign starting power device selected by the C919. It should be said that the engine is indeed a major constraint in the development of China’s large aircraft, and it can only be sought from people at present. However, I believe that in 10 to 15 years, China will be able to develop its own advanced aero-engine for large aircraft.

　　③ Have a number of scientific and technological innovations.

　　Experts said that the C919 was completely designed and integrated independently, with outstanding technical indicators. It is the persistent innovation of researchers who have sharpened their swords for ten years that has led to the high-tech C919, which integrates many key technologies.

　　However, what did C919 look like when it was approved as one of the 16 major projects in the national medium-and long-term science and technology planning in January 2006? What difficulties may be encountered in the development? Due to the limitation of western aviation powers in technology introduction, China researchers have no idea and can only cross the river by feeling the stones.

　　In November 2008, the C919 project was launched. A large passenger aircraft joint engineering team composed of 468 experts from 47 domestic and foreign units, plus a large passenger aircraft expert consulting group composed of 20 academicians and experts, started from sketches and gradually sorted out the first batch of 14 special technical research projects that need to be started.

　　Among these key technologies, there are several that must be mentioned. For example, the "supercritical airfoil" that makes airplanes more fuel efficient. A large passenger airliner is an out-and-out "oil tiger". In order to reduce fuel consumption, the wing design of C919 uses a supercritical airfoil, which improves the cruise aerodynamic efficiency by more than 20% and reduces drag by about 8%.

　　Another unique innovation is the adoption of the third generation Al-Li alloy materials. It is the first time in China that the world’s advanced third-generation Al-Li alloy materials are widely used in the main structure of C919. Compared with ordinary aluminum alloy, this lightweight metal material with high damage resistance has greater strength and lighter weight under the same strength, which is very important to realize the weight reduction of aircraft structure and greatly improve the service life of aircraft.

　　In addition, as the "brain" of the C919, the avionics system of the aircraft has realized "giving all the work to the network". Compared with the old version of the network, which was widely used before but had limited bandwidth, the new aviation bus communication protocol adopted by C919 not only has high bandwidth but also shares resources, which means that the signals that originally needed to be transmitted through several cables can now be transmitted by one cable. Experts said that this is like we need to run 10 trains from A to B, but we don’t need to build 10 railways. We only need a set of double-track railways and a reliable signal system.

　　According to Wu Guanghui, the chief designer of C919, the developers have planned 102 key technical problems, and many advanced materials have been applied on a large scale in domestic civil aircraft for the first time. The development process of millions of parts and airborne systems is highly parallel. In order to overcome these technical difficulties, 22 provinces and cities, more than 200 enterprises, 36 universities and hundreds of thousands of industrial personnel participated in the development of C919 large passenger aircraft, and 16 material manufacturers and 54 standard parts manufacturers including Baosteel became suppliers or potential suppliers of large passenger aircraft projects.

[Interpretation]

Reading on a Winter’s Night and Showing Children’s Yue is a group of eight poems taught by Lu You. This poem is the most famous third poem, which was written at the end of the fifth year of Qingyuan in Song Ningzong (1199). Zi Yu is Lu You’s youngest son. In his poems, Lu You encouraged his son to work hard and persevere in learning, emphasizing that learning can not be satisfied with book knowledge, but must be "practiced" — — Only by learning and applying knowledge in practice can we achieve something.

The first two sentences of the poem say that the ancients always tried their best to learn, and only by working hard when they were young can they achieve something in the future. The word "no effort" summarizes the degree to which the ancients worked hard and tirelessly in learning. The last two sentences, "I feel shallow at the end of the paper, but I don’t know how to do it", are poetic eyes. Paper: books. Know nothing: understand deeply and thoroughly. This means that the knowledge gained from books is inevitably superficial, and to thoroughly understand things, you must practice it yourself. Lu You emphasized the importance of practice from the relationship between book knowledge and social practice. This feeling of the poet’s reading in winter night is the most profound understanding of his life as a scholar. He told his son: a person who has both book knowledge and practical experience is a truly learned person; Reading must strive to achieve "heart-to-heart, eye-to-eye, mouth-to-mouth", and can draw inferences from others in practice to achieve mastery.

　　The layout of the Forbidden City embodies the designers’ wisdom. The clever thinking of "facing the mountain and facing the water" is one of the obvious characteristics. Jingshan Mountain is in the north of the Forbidden City, and Neijinshui River is in the south. There were no mountains in Beijing. When the Forbidden City was built in Yongle period, more than 1 million cubic meters of soil was excavated by opening a moat, and the piles of muck demolished by the Yuan Dynasty Palace could not be treated. So, a "waste utilization" came, which piled up the soil into mountains and planted trees on them. This is the Zhenshan in the north of the Forbidden City. Zhenshan was called "jingshan park" in the Ming Dynasty, and it was renamed "Jingshan" in the Qing Dynasty, and it has been used ever since. Jingshan is the commanding height in Beijing, which is east-west and narrow in the north-south direction, much like a screen. At the same time, when the Forbidden City was built, a culvert was dug downstairs from the northwest corner to introduce the moat water into the city. This is the specially dug Jinshui River. Jinshui River winds south through Chenglong Temple, winding all the way, turning east through Wuying Hall, passing Taihe Gate and Wenyuan Pavilion, and flowing out of the Forbidden City from the southeast corner. Jinshui River not only provides drainage channels for people in the Forbidden City, but also echoes with Jingshan Mountain, forming an aesthetic image of mountains, rivers and mountains in harmony. The surface of Jinshui River is lower than the ground of the Forbidden City, and the main part of the Forbidden City is built on the balcony between Jingshan and Jinshui River. Through Jingshan Mountain and Jinshui River, the Forbidden City is in harmony with nature in the aesthetic sense.

　　"negative yin embraces yang" is also a feature of the layout of the forbidden city. All the important palaces in the city face south. Chapter 42 of Laozi’s Tao Te Ching says: "Everything is negative and holds Yang, and rushing into the air is thought to be harmonious". It means that everything in the world is shady and sunny, and yin and yang interact to form a new harmonious body. The important palace buildings in the Forbidden City face south, with a large number of doors and windows in the south and fewer doors and windows in the north. The Book of Changes, Zhuan Zhuan Zhuan, says, "Sages listen to the world from the south, and govern from the Ming Dynasty", which means that the ancient sages ruled the world by listening to the south and facing the bright sunshine. Similarly, this layout has scientific significance in geography: the Yellow River Basin in China is located in the most remarkable subtropical monsoon climate area in the northern hemisphere, and in winter, a high pressure is formed in the northwest of the Asian continent, with a northerly wind for several months; In summer, the center of high pressure turns to the southeast Pacific Ocean, and the rainy monsoon from the south makes the temperature rise and the summer heat pressing. Under this geographical condition, it is most suitable for the building to face south, with the north side closed to keep out the cold, and the south side with windows for sunlight and ventilation in summer.

　　Another feature of the layout of the Forbidden City is "taking the positive center". "Correcting" means that the north-south direction is the main axial direction of the building layout. This is mainly due to the construction experience of ancient Chinese craftsmen based on the geographical location and natural environment of China, that is, the main seat faces south and is symmetrical left and right. "Centripetal" means that all secondary buildings face the main building. All the ancient buildings in the Forbidden City are mainly quadrangles, with the main rooms facing south and the wing rooms facing east and west. This centripetal architectural style not only makes the distance between houses smaller, which is conducive to the convenience of transportation, but also reflects the idea of "China is supreme" and "China is still big" in ancient China culture. At the same time, this orientation layout reflects the unity and coordination of the ancient buildings in the Forbidden City, and there is no sense of clutter.

　　The architectural division of the Forbidden City is also particular. From the perspective of architectural functional zoning, the layout of the Forbidden City includes the imperial court area and the imperial court area. The buildings of the former dynasty were located in the south of the Forbidden City, mainly including the Hall of Supreme Harmony, the Hall of Zhonghe and the Hall of Baohe (commonly known as the Three Great Halls), which was the place where the emperor held important ceremonies. The imperial palace buildings are mainly located in the northern part of the Forbidden City, including Ganqing Palace, Jiaotai Palace, Kunning Palace (commonly known as the last three palaces) and the East and West Six palaces, which are the places where emperors and empresses live. The three great halls of the former dynasty occupied a large area and formed a huge pattern in the Forbidden City. These three buildings stand on a three-story platform, which is 8.13 meters high and takes the form of Sumitomo. Sumeru is actually the base of the Buddha statue. "Sumeru" is an Indian Buddhist term, which means "the center of the universe". Sumeru is used as the foundation of the building, which means that the building is stable and long-lasting. The three-story platform of the three halls can highlight the grandeur and height of the building, form an obvious contrast with other buildings in the Forbidden City, and highlight its extraordinary position. Not only that, the three halls are elegant in richness and dignified in exquisiteness, which highlights the majesty of the emperor. The Three Great Halls are not only the center of the Forbidden City, but also the center of Beijing, with the axis from Yongdingmen in the south to the Bell Tower in the north, becoming a straight central line. On both sides of this axis, buildings with less important functions are arranged symmetrically and orderly in turn. There is also a square with an area of 30,000 square meters in front of the Hall of Supreme Harmony. This layout is conducive to showing a grand scene when holding important ceremonies.For the six palaces of the East and West, they are symmetrically arranged and vertically arranged. These buildings are separated vertically and horizontally by the East-West Second Long Street and the alleys in front of the palace, forming a very regular and rigorous closed space with streets and lanes, and the doors and walls of the seats are connected and separated. In their own space, that is, in the independent courtyards of each palace, they have the same layout and basically the same architectural form. The plane of each palace is square, and the layout is in the form of a three-in-one courtyard with two courtyards. The front hall and the back bedroom are all equipped with halls, which are strictly symmetrical. The layout of the courtyards of the East-West Six Palaces is subtle and compact, which not only guarantees the privacy of the life of the Empress Dowager, but also has reasonable planning: "How deep the courtyards are" can reflect the location characteristics of the East-West Six Palaces in the Forbidden City. On the whole, the architecture of the former dynasty was Yang, and Yang was majestic and tall. The architecture of the imperial palace is yin, and yin converges to the reality of hiding. The six palaces in the east and west and the three halls form a harmonious and unified wisdom thought of rigidity and softness, yang and yin.

　　In addition, the architectural layout of the Forbidden City was convex in the former dynasty and concave in the imperial palace. The combination of convex and concave is just like a mortise and tenon. This layout of tenon-mortise connection not only shows the ingenious tenon-mortise locking concept of the ancient buildings in the Forbidden City, but also embodies the concept of "Yin and Yang in one" in ancient Chinese architectural culture, which is a reflection of the wisdom of the builders of ancient architecture.

This generation of young people have long been unable to integrate into the social process of "eating and drinking mahjong KTV" of their parents, but in reality, they are limited by time and space and cannot expand their social circle. They establish contact with strangers outside the life and work circle through online games and thus have emotional connections. Games have become the social currency of a new generation of young people.

Mobile games and e-sports have long been popular in the streets. At the moment of winning the championship, the popularity in bilibili live broadcast room has reached more than 400 million, and the popularity of Tiger Tooth live broadcast has reached more than 300 million. Judging from the popularity of its various online platforms, e-sports live broadcast has long been a national entertainment activity.

The market scale of the game has derived the social demand of the game, and the upcoming TT focuses on the social voice of the game, thus harvesting 100 million users. However, under the precedent of many social platforms that died of social atmosphere, 90% of users are TT voices after 95 s and 00 s, but people have to worry, can game-based socialization go on healthily?

From game voice to social tools

At first, TT voice was just a voice tool.

In 2012, the mobile game industry in China began to enter an explosive period, and a large number of game practitioners rushed into the game content production industry in an attempt to create an explosive game. However, at that time, most games were still in the initial stage, and there was no perfect voice communication system, but the need for players to communicate in time was very urgent.

Based on this, Fun Pill Network chose to start from the game voice tool. In 2014, TT voice became an instant hit. In the first year, the number of registered users exceeded 3 million, and the number of online users exceeded 60,000. In one year, the running water exceeded 100 million yuan.

However, it is difficult for tool apps to achieve considerable revenue. Moreover, after 2016, more and more games that need to be "blacked out" have added built-in instant voice systems, and the core business of TT voice has been impacted, not only because the ceiling is too low, but also because the tools themselves have become chicken ribs.

"Blackout" in the game itself is a social way, therefore, social transformation has become the easiest path for TT voice to cut in. In 2018, TT voice gradually added live voice, expanded chat, pia drama, dynamics and other kinetic energy, which was deeply tied with explosive mobile games such as the glory of the king and Peace Elite, enabling gamers to directly perform voice hacking, teaming up, scoring and other operations within TT voice, broadening the use scenarios of TT voice, and the average online market for daily users exceeded two hours.

In the field of game socialization, TT voice can be regarded as a deep-rooted player. For example, in finding a playmate, the glory of the king’s matching mechanism does not allow too much difference between segments. Many players find it difficult to match the right teammates and opponents with the same segment because the segment is too high or too low, but TT Voice can find the right playmate with the same segment based on the game and gender, so as to recognize gamers who have the same topic cognition.

In fact, not only mobile games like the glory of the king Peace Elite have voice social needs, but other games also have voice social needs, but many minority games have no funds and strength to add voice built-in and social channels. The "quick matching" of the "black channel" on TT voice homepage not only covers high-heat mobile games such as the glory of the player, the peaceful elite, the call of duty, the fifth personality, but also covers leisure and educational games such as light encounter, gobang, you draw and guess, which makes TT voice not a vassal of a certain game, but the best playmate of the game, and can inject fresh blood into the platform while stabilizing old users.

In addition, TT voice is not only satisfied with finding suitable game playmates for players, but also based on user interest tags and other information, using system algorithms to gather people with similar interests in the virtual room voice room by distributing playmates, finding radar and other functions, and sharing audio, video, pictures and other contents in real time to achieve the purpose of making friends. In addition to "playing in black", TT voice also opened content sections such as finding playmates and entertainment.

Judging from these functions, TT voice is not only a tool, but also a social ecology based on games, which meets all the online entertainment and leisure needs of this generation of young people.

Therefore, TT voice also has a living space outside the game content. According to publicly disclosed data, the unique TT voice has accumulated more than 100 million users by 2020, an increase of more than 80% from the previous month. In addition, the platform MAU reached 20 million, of which the post-95 s, that is, Z generation users accounted for as high as 90%.

During the first half of 2021, users spend about 158 minutes in TT voice chat rooms every day, and users initiate more than 850,000 voice chat rooms every day, an increase of 45.6% compared with the same period in 2020.

Sullivan pointed out in the report that TT voice has become the largest mobile voice social platform and the largest player-centered mobile social platform in China according to monthly users and income data.

The ceiling is too low and it is too difficult to grow.

According to the data of China Game Industry Report 2020 released by China Game Industry Research Institute, the number of game users in China will reach 665 million in 2020, with a year-on-year increase of 3.7%. In other words, there is one TT voice user in every six e-sports players.

However, it is worth noting that TT voice is actually known outside the deep e-sports players. Because almost every popular game has its own social function, players can achieve basic needs such as communication and team formation in the game. With the improvement of the voice communication system of the game itself, the chances of players opening the voice-assisted APP are bound to gradually decrease.

Therefore, it is not an exaggeration to say that TT voice survives in a crack, and this crack makes it difficult for TT voice to make a breakthrough in market scale.

In addition, there are too many voice social software, and the substitutability of TT voice is very high, not to mention that WeChat QQ can open black communication games in groups, and there are also black-opening software such as YY voice, KK voice and hello voice in the market to compete with it. In contrast, the competitive advantage of TT voice is not clear.

According to the prospectus, in the first half of 2021, the monthly activity of TT voice reached 16.2 million. Compared with the social products such as Gathering Times and Momo, the number of monthly users of less than 20 million is not large enough.

The ceiling is too low, the loyalty is not enough, and the user payment rate is also very low. According to the data in the prospectus, the monthly living payment rates from 2018 to 2020 were 7.3%, 7.1% and 5.3% respectively, and even fell to 5.1% in the first half of 2021, the lowest level in history.

In addition, the target users of TT voice are the post-95 s and post-00 s under the age of 24, but this young group has limited spending power and it is difficult to promote more consumption.

Moreover, the acquisition cost of TT voice is not low. According to the prospectus, in 2020 and the first half of 2021, the network and marketing expenses of Fun Pill Network increased by 123.06% and 120.88% year-on-year, both higher than the revenue growth in the same period and higher than the growth rate of paying users.

In addition, as an auxiliary tool APP, TT voice also needs to solve the problem of user retention. At the beginning, TT voice can be downloaded because of the formation of playmates, but after a short period of acquaintance and pairing, playmates who form fixed friends often develop into daily communication software such as WeChat /QQ for voice, dialogue, making friends, opening black and other activities.

As far as social tools are concerned, most of WeChat and QQ are bound with offline real social information, so the probability of users uninstalling software and accounts is very low, but only a small social APP with Internet strangers’ "friends", which leads to a higher probability of uninstalling software and accounts because of the low maintenance cost, making it difficult for users to really keep them.

In this way, TT voice has become a diversion middleman of WeChat QQ, and it is difficult for users to really stay. In fact, this problem is not only the embarrassment of TT voice, but also the embarrassment that all niche social tools except WeChat QQ are difficult to solve.

Risk involved in gray areas is high.

Almost all Internet companies want to socialize, and Ma Yun’s Alipay is no exception. However, social functions are easy to build in, but it is extremely difficult to make social apps.

In particular, it is indeed the common demand of a new generation of young people to make friends through games, but social interaction based on games can be an interest, but it is also easier to deteriorate.

With the development of Qinglang Action, many accompanying software such as "Bixin", "Little Deer Accompanied Play" and "hello Voice" have been taken off the shelves indefinitely because of illegal activities such as fraud and pornography, and social software accompanying games has become a high-risk zone for juvenile supervision.

Although TT voice has not been removed, it does not mean that it does not have this problem. On the home page of TT voice, the online number of blind date rooms has exceeded that of black-out, party, listening to songs and other rooms.

The content of "edge ball" can be said to be the user’s low quality, but TT voice belongs to the "ignition" in this kind of edge ball socialization, and the official attitude may even imply encouragement. Many users reported that TT voice received an "immediate private chat" automatically matched by the system after the initial download and registration, and the dynamic recommendations were all kinds of speeches and private messages.

Some media reports have pointed out that TT voice has voice rooms named after minors, and some voice rooms have voice contents such as suspected obscenity and abuse, and the report pointed out that the platform did not block these live broadcast rooms during the investigation.

On the black cat complaint platform, the number of complaints about TT voice is as high as 2,705, which is more than two old-fashioned voice software such as Momo YY live broadcast. The complaints include problems such as fraud, inducing minors to pay, and swearing.

There are also public reports this year. A 9-year-old girl from Guangzhou once got to know the suspect Lu Mou after downloading TT voice chat dating platform. Lu Mou gave her a red envelope in the name of giving gifts. Due to lack of judgment, she was cheated for 12,781 yuan.

TT voice expanding social interest content outside the game may encourage dangerous discussions. In the "expanding column" section of TT voice, there are a large number of underage users, and most of them are involved in puppy love, and the situation is extremely serious. The section of "Minors posting to find boyfriends in public" even has a very obvious recommended position in the APP, and even pornographic content shows obvious recommended positions, as well as obscure yellow-related drainage stickers.

Although social software can’t supervise all users’ languages, the target users of TT voice are mainly minors and young students under the age of 25. Are you sure this high-risk social interaction is not playing with fire?

At present, TT voice has no underage review mechanism. After downloading, registration can be completed only by receiving a four-digit verification code from the mobile phone, which means that minors can complete registration without even unlocking their parents’ mobile phones, and can be used to contact all users without their real names or any third-party information.

Judging from its official attitude, although the youth model has also been established, most of the contents under the model are subject education courses. Obviously, there is no active and healthy planning and guidance for the healthy socialization of minors’ interests.

Although the state has issued policies to restrict the related behaviors of minors’ games, the surrounding industries of games also need strict supervision. Whether it is live broadcast or accompanying play, enterprises should actively fulfill their responsibilities to protect young people, and should not lower the lower limit in pursuit of market scale.

In recent years, there has been a constant debate in public opinion about the reform of CET-4 and CET-6, and even the debate about whether to keep or abolish it. In the future, how to evaluate the English proficiency level is worthy of attention.

　　College English Test Band 4 and Band 6 starts today.

　　According to the news from the Examination Center of the Ministry of Education, the CET will be held on December 14th in the second half of 2019. Among them, 9: 00 am & mdash; Take CET-4 at 11:20, and at 15:00— At 17:25, the CET-6 will be conducted.

　　On the eve of the exam, many provincial education examination institutes issued a reminder that candidates must enter the examination room with the admission ticket, student ID card and valid ID card on the day of the exam (starting at 8:45 am and starting at 2:45 pm), and the "three certificates" are indispensable. Admission is forbidden after 15 minutes.

　　During the examination, candidates are only allowed to bring necessary examination stationery into the examination room, and are not allowed to bring books, materials, bags and other items. It is strictly forbidden to bring electronic equipment with the function of sending or receiving information. Once found, it will be dealt with in violation of regulations, and the results will be invalid.

　　According to the pre-test reminders issued by various places, before the exam, there are often some lawless elements and intermediaries in the society who use the Internet and other tools to publish harmful information such as "helping the exam", "providing real questions" and "answers" and peddling cheating tools, and claim to "package" to defraud candidates of money. Please don’t believe in false propaganda, so as not to be deceived.

　　Under the current examination system, the CET written test is held twice a year in June and December of each year. In June, all subjects in English and non-English are taken, and only English subjects are taken in December. CET oral test is held twice a year, in May and November each year.

　　Debate on the reform of CET-4 and CET-6

　　The National College English Test Band 4 and Band 6 is a large-scale standardized test sponsored by the Ministry of Education and presided over and implemented by the Examination Center of the Ministry of Education. Since its implementation in 1987, CET-4 and CET-6 have gone through more than 30 years, accompanying the youth of generations of students.

　　In order to constantly meet the needs of students learning English, CET-4 and CET-6 have been on the road of reform. The reporter found that in recent ten years, various reform schemes, such as taking multiple questions and volumes, canceling cloze, increasing Chinese-English translation scores, and changing fast reading comprehension into long reading comprehension, have been implemented in CET-4 and CET-6.

　　On October 23 this year, the plenary session of the National College English Test Committee for Band 4 and Band 6 in the second half of 2019 held in Shanghai said that the use of artificial intelligence technology has obvious effects on improving the quality of marking papers, and it is suggested to further strengthen research and gradually promote it. Moreover, the CET test system still needs to be further improved, and it is suggested that CET oral test should be included as a compulsory subject as soon as possible, which is beneficial to college English teaching.

　　In fact, in recent years, some experts and scholars have called for "canceling the CET-4 and CET-6 examination" and "turning to the socialization level examination".

　　In January this year, Cai Jigang, a professor at Fudan University and the president of China Academic English Teaching Research Association, published an article in the media entitled "CET-4 and CET-6 can be turned to socialization level test". According to the article, CET-4 and CET-6 have even seriously affected the higher requirements of college English, and standardized tests have also affected or even seriously affected the development of college students’ critical thinking ability.

　　In Cai Jigang’s view, higher education is a systematic process, and each major or course can’t be selfish. College English can only be a service course. Different disciplines and majors have different needs for English, and the English proficiency test should not be "one size fits all". CET-4 and CET-6 should be turned to socialized proficiency test as soon as possible.

　　At the same time, however, there are voices that the CET-4 and CET-6 can’t fully reflect the level of the subjects, but its existence value should not be denied.

　　According to a commentary published by China Youth Daily at the end of 2017, CET-4 and CET-6 cover listening, reading, translation and writing. At the same time, an oral test is set, which covers listening, speaking, reading and writing, and the test items are relatively flexible. Compared with IELTS or TOEFL, which cost thousands of registration fees, CET-4 and CET-6, which can be applied for only tens of yuan, is still the "gold standard" for evaluating the English level of most China students.

　　Chu Zhaohui, a researcher at China Academy of Educational Sciences, told Zhongxin.com that although CET-4 and CET-6 have played a lot of positive roles in history, the shortcomings of their unscientific inspection standards and insufficient pertinence have hindered students’ English learning. Relevant departments may wish to listen to the suggestions of academic circles and replace them or carry out more drastic reforms.

　　When will the future English test come?

　　The reporter noted that as early as 2014, the State Council issued the "Implementation Opinions on Deepening the Reform of Examination Enrollment System", proposing to strengthen the construction of foreign language proficiency assessment system, which is the first time at the national level to put forward clear requirements for the comprehensive reform of foreign language examinations.

　　In February 2018, the Ministry of Education and state language commission officially released the China English Proficiency Scale, which is the first English proficiency assessment standard for English learners in China. At that time, when answering a reporter’s question, the person in charge of the examination center of the Ministry of Education said that on the basis of the scale, the examination center of the Ministry of Education was developing the English proficiency test.

　　In December this year, Yu Han, deputy director of the Examination Center of the Ministry of Education, revealed at the 2019 TOEFL annual meeting that the overall design of the China English Proficiency Test has been completed at this stage. "The focus of the previous research is to develop exams corresponding to the corresponding levels of higher education. At present, the design and demonstration of the examination syllabus have been completed, and the test work has been carried out in some colleges and universities. "

　　In view of the speculation that China English Proficiency Test will replace CET-4 and CET-6, on December 11th, the relevant person in charge of the Examination Center of the Ministry of Education responded to the media reporter and said: How to integrate the new system with the existing examination items and do a good job in inheritance and development, we are studying and widely listening to opinions.

　　In addition, it is worth noting that another national-level general English test — — The National English Test has been suspended in Sichuan, Liaoning, Jiangxi and Henan provinces.

　　The comprehensive reform of foreign language examination is progressing continuously, but the final direction of CET-4 and CET-6 is still inconclusive.
