In the 20-year battle between the kings of heaven, has Jay Chou crushed Lin Junjie?

Text | Music Herald, Author | Ding Qiwen, Editor | Fan Zhihui

Farewell to 2023, the Chinese music scene is still turbulent.

Since the release of the new song "Christmas Star" in late December, the discussion about Jay Chou has continued to rise, and he has still stood on the trend wave for nearly half a month. The reason is that in addition to the national popularity of "apotheosis" that he has carried for decades, it also stems from the controversy over whether "Zhou Lang is done" every time he releases songs in recent years.

However, the controversy brought by "Christmas Star" this time is not only around whether it is ugly or not, but also set off a "water injection war" between Jay Chou fans and Lin Junjie fans, and even rushed to the forefront of Weibo’s trending topic list.

Subsequently, it evolved into the "base" of the fan group war, and Jay Chou fans pointed the finger at the management of Lin Junjie’s official support club in the comment area of several bloggers, saying that he "issued a task to Lin Junjie fans" to maliciously slander, while Lin Junjie fans believed that this was a "surrounding the forest to save Zhou" drama planned by the "opposite family" to divert unpleasant and Zhou Lang did his best to save public opinion, and the contradiction between the two sides gradually escalated.

Why are the fans of Jay Chou and Lin still arguing about "the only top class in the Chinese music scene" after decades of circling around?

The King of Heaven fights the peak of the Forbidden City

There is no doubt that in this year’s fully liberalized music market, both Jay Chou and Lin Junjie will continue to lead in the "King of Heaven".

Although Jay Chou belatedly released only the single "Christmas Star", he still continued to set a record at the top of the chart. In addition to landing in Taiwan Apple Music, iTunes, YouTube, mainland QQ music in-app seven charts, but also led all past works back to the QQ music Rising Star Ranking, released nearly a week "Christmas Star" is still ranked first in the QQ music station, even to the beginning of 2024, it is still in the top ten of the station.

Compared with Jay Chou, Lin Junjie is more productive, only in 2023 released a solo album "regain _ happiness", "JJ’s coffee tone" two series of cover albums, as well as "curtain call" "In The Joy" "The Show" three singles, of which "regain _ happiness" CD version also set a continuous top the chart in Taiwan’s five gold list Chinese list for four consecutive titles, vinyl version also set a record three consecutive titles.

In this year’s Spotify released the list of singers with the most streaming listenings in Taiwan, Jay Chou continued to rank first, while Lin Junjie ranked ninth, which is also the only male singer on the list who has crossed over from the millennium period to the present. It is also the first and second Chinese pop singers and male singers in Spotify’s world with the most streaming listenings in 2023.

No matter whether it is Jay Chou or Lin Junjie, his past classics still show strong vitality this year.

For example, Jay Chou’s "Fantasy" album released in 2001 continued to sell well in Taiwan’s five major record charts last year, and "Chopin in November" and "The Greatest Works" also entered the top ten albums in Spotify Taiwan with the most streaming listenings this year; Lin Junjie’s past digital singles "Exchange the rest of my life" and "Ask for the day at night" won the top four best-selling digital singles in NetEase cloud in 2023; relying on many classic works, the annual hit list of Apple Music Chinese mainland in 2023 was also swiped by Jay Chou and Lin Junjie, of which Jay Chou was in the top ten of the butcher list, with a total of 55 songs in the TOP 100.

On the other hand, with the recovery of the performance market, Jay Chou and Lin Junjie’s concerts are very popular, and the second space and additional performances are in full swing, but the same cannot help but have similar doubts.

Jay Chou, who sold out all the concert venues in 2023, was accused of singing in Fuzhou, which was about to start singing in mid-May 2024, but opened the pre-sale on December 9, 2023, for half a year. This also caused consumers to be extremely dissatisfied with the long pre-sale time and the high 30% handling fee for refunding tickets. Jay Chou was also ridiculed as "ugly to eat", and many related topics also rushed into the hot search.

Lin Junjie, who is also sold out in 2023, also caused controversy in December. He condemned the spoofing and popularity of the concert hot dance clip by Douyin netizens as "not funny and disrespectful" through IG, and bluntly said "Please don’t come to my concert next time", which also made the consumer market complain, and some netizens said "Don’t come to the mainland to hold a concert since this is the case". Moreover, the two’s overseas concerts such as Malaysia and the United States have generated attendance controversy.

However, in comparison, what was questioned more was the listening data that Jay Chou had brought about.

As mentioned above, the user record of listening to "Christmas Star" for more than 10,000 minutes appeared within one minute of its release, and Jay Chou was also dubbed "water injection". As Lin Junjie’s fans participated in this wave of questioning, Lin Junjie’s old "Jiangnan" was also accused of more than 10,000 minutes of abnormal listening. And this so-called abnormal listening time has also become "evidence" for fans from both sides to argue.

However, according to many netizens, the display of more than 10,000 minutes originated from the personal behavior of QQ Music users to upgrade the "sound power" and occupy the high position of the user’s listening display page.

"Laotan Sauerkraut", who is engaged in brushing, said that with the open user listening to the general list page of the online music platform, the brush business of this mechanism has already formed an industrial chain, and a few cents can buy the listening time of designated songs in Xianyu, Taobao, and Pinduoduo."The basic 260 minutes is usually relatively cheap without specifying songs, most of which are 0.7 yuan.More than 10,000 minutes of the deluxe version can specify songs, and the price is around ten yuan. Many fans will come to buy the duration in order to pursue the top ranking. "

However, he also stressed that this kind of swiping will not affect the fluctuation of song popularity, "at most it will affect the ranking of the user himself on the song listening page". This is because, even if the listening time can be controlled, the QQ music daily listening statistics rules are not based on the listening volume to count the popularity of songs, but to prevent the swiping of the list.

The availability of listening time also allows fans to obtain the "privilege" of being an iron fan logo and high exposure of the account, and even become the "big fan" blogger of artists and have fans to follow. "In fact, some regular customers who often buy back are also in order to become the talent number in the QQ music station for the owned account, or to be on par with the Weibo big V identity and maintain the big fan profile."

In addition, this dispute between the king of heaven, which spread from new song listening to concerts and other fields, also caused many leading bloggers in the music circle to "end" to join, further intensifying the contradiction between fans. For example, the bloggers "Music_Data" and "LiveMusic Live" stood on one side, and posted several Weibo to consolidate the "king of heaven argument". Its comment area once became the main battlefield for fans on both sides to denounce each other.

Similar scenes have been played out frequently since the turn of the millennium, and the fan war about "who is the real top king of the Chinese music scene" will never convince anyone.

But just as Tao Zhe said after facing the popularity of Wang Leehom, Jay Chou and other younger generations,"King Zhou? Good music, Leehom Wang? Good music, why can’t there be more? I also like their music very much. This market is not mine, it belongs to everyone."

Why did the "Zhou Lin" war last for so many years?

Back in the millennial era, there are not only the first Chinese R & B person, but also the creative genius who emerged. In the eyes of most people, the "Four Heavenly Kings" in Taiwan who once led the Chinese music scene are nothing more than Jay Chou, Tao Zhe, Wang Leehom, and Lin Junjie.

In 2004, Lin Junjie, who had just won the 15th Taiwan Golden Melody Award for Best Newcomer, released the album "Second Heaven", officially joining the "King of Heaven" competition among popular singers such as Tao Zhe, Wang Leehom, and Jay Chou. Even though Wang Leehom and Tao Zhe also have recognized creativity and many representative works with high singing degree, among them, Jay Chou and Lin Junjie, who have a similar route, have become the default competition relationship.

Since then, the debate about who is the peak of the Chinese music scene between Jay Chou and Lin Junjie has never stopped.From the perspective of creation, singing, character, word-of-mouth, etc., it can cause endless chaos.

But on the other hand, the intensification of this competitive relationship has now become a vigorous online connection, reflecting the changes in the ecological environment of the entire industry behind the channel transfer of the Chinese music scene from the traditional recording era to the Internet era.

The most obvious is that musicians have gone from producing and polishing the music works on a record for the hot sale of records, to now a digital single can be sold for a fee; and the way the public listens to music is no longer a CD, MP3, such as a certain "stand-alone" way. The digitization of the streaming media era also allows everyone to comment on communication and consume music "painless".

The biggest change is whether the quality of music is good or not. It is no longer the key issue that determines whether a singer is popular or not. Instead, it is the algorithm and traffic. The change in channel influence has also made music standards more hierarchical, depending on the opinion.

Just as now, "Christmas Star" is accused of having straightforward lyrics that are not as good as Jay Chou in his early years, "The Show", which Lin Junjie collaborated with European and American musicians, has also been rated as "uncharacteristic", "earth hi dance" and so on. The quality of music is also judged from the professional dimension. Instead, it is cut in many ways by netizens in the powder and black war. This also reflects the contradictory aesthetic system of the public – the contradiction between sun spring and white snow and the people of Xialiba.

To put it bluntly, this is also a change that has the voice over the music industry, that is, from record companies, producers, musicians, and professional music critics to every user with a smart phone.

Of course, the so-called aesthetic is subjective, and the war between fans and listeners is also a tangle of genres and creative dimensions in the Chinese music scene.

Under the impact of the popularity of short videos, the decentralization brought about by the segmentation of the market has also made the exposure channels and voice channels more depressed. With the increasingly obvious aesthetic differentiation and the generational fault in the music industry, the terms "the first king" and "the first in the Chinese music industry" have become increasingly blurred. The preferences of thousands of people and thousands of faces can always come to the definition of the first or king in the hearts of different audience groups.

After all, in today’s era when "subject three" has become a popular representative of cultural output, the professional awards and charts of the traditional recording industry era have long lost their baton in the rise of the lower-tier market.

With the rise of Y2K, the 90th and 00th generation of listeners who grew up in the millennial era and are now the main consumers have also pulled the Chinese music scene back to the retro trend. Coupled with a steady stream of new audiences joining, new interpretations of the "King of Heaven" continue to emerge in the succession of generations. For example, today, the King of Heaven dispute has long since moved from the dimension of healthy competition to the ending of being carried away by the fangirl culture, such as mutual stepping, the navy and the army are black, the mindless standing in line or reaching the point of "human flesh" against fans.

On the other hand, it is precisely under the tolerance of the rice circle that the kings who have spanned the Chinese music scene for more than ten years have also fallen into the question of eating old money and consuming fan economy at a time when music cannot cross the era and IP products harvest fan consumption.As the MCHOTDOG hot ** when the new songs are suspected of Diss Jay Chou "eating old money" and "using fans as cash machines", "I am scolding everyone, not just Jay, I am scolding myself".

Perhaps today, the public is still happy to see Jay Chou and Lin Junjie fans fighting for the top-class king name. After all, they still hope that in this era of diversity and inclusiveness, they can see "divine work immortals" break through the ground under heavy pressure and reproduce the years when immortals fought.

conclusion

From the millennium to the present, the showdown between Jay Chou and Lin Junjie has also been regarded as a battle of the century in which both the public and fans participate.

Looking back, with Jay Chou and Lin Junjie’s dispute over the heavenly king lingering for several years, what we can see is that there is no new era of superstars in the Chinese music scene, and it is more of a flash of meteors, and even a short-term explosion is unconvincing.

In other words, this is an era that does not require Heavenly Kings, and the top of the Forbidden Heavenly Kings is just a floating cloud.

Go! Go to the same clock in Peng Yuyan Shenzhen Park

Original, special commentator Xie Weifeng, released in Shenzhen

How did you meet Peng Yuyan by chance?

If this question is answered by the people of Shenzhen

There is a high probability that you will receive a knowing smile.

Recently, the news that Peng Yuyan went to Shenzhen Bijia Mountain Sports Park to run was on the hot search. He experienced intelligent fitness equipment, and the interaction with AI made him cry out for novelty, praising again and again: "Shenzhen’s parks are very powerful!"

If Wu Yanzu is an adjective, then Peng Yuyan should be a verb, a movement of sports. As a high-quality idol, Peng Yuyan’s story of going from a little fat to a figure benchmark in the entertainment industry has inspired many young people to sweat like rain on the sports field and say "no" with effort and greasy!

When he came to Shenzhen Park to run, Peng Yuyan could be said to have done a "high score" multiple-choice question correctly. Some netizens called Peng Yuyan from the air: "Move to Shenzhen to live, you can go to the park to exercise when you have time. There are many parks in Shenzhen, you can run in the grass, under the flowers and trees, on the mountains, by the river, on the lake, and on the beach…" From these words, there is a sense of happiness that "the city is in the garden, the garden is in the city", and those who know Shenzhen can feel the "sincerity" in it.

"Shenzhen Release" Message

Now, isn’t there a "20-minute theory in the park" popular? Studies have shown that spending a short amount of time outdoors every day can make people happier. Even if you don’t exercise, just spending 20 minutes in the park every day can make you better. It is research that cannot be decoupled from reality. The search for samples is particularly important, and Shenzhen is the most suitable city to verify the authenticity of the "20-minute theory in the park". On this less than 2,000 square kilometers of land, there are 1,290 parks of all sizes, and the service radius of the park green space is 500 meters. The "Spring Mountain" in this city at a glance is the main one "Push the window to see green, open the door and enter the park".

As a first-tier city in China, Shenzhen is undoubtedly at the forefront of the country in terms of economic quantity. Up to now, an inch of land is not enough to describe the preciousness of land resources, and every square meter has careful calculations. The trade-off between priority and priority is a test of how Pengcheng can "draw the most beautiful pattern on a piece of white paper," while the large amount of green for park construction shows the city’s heart.

"In Shenzhen, I visit five parks in one go" is really not just talking about it. This year, the "Five Gardens Unicom" in the center of Shenzhen, the current Meilin Mountain Park – Yinhu Mountain Park – Bijia Mountain Park – Central Park – Lianhuashan Park can already travel all the way. How can 20 minutes be enough when you open your door?

Speaking of Bijia Mountain Park, it is the place where Peng Yuyan clocked in this run. As the first sports park in Shenzhen, it has become a running destination for many Shenzhen people since it was refurbished and opened in 2023. However, for Peng Yuyan, a veteran sports enthusiast, to say that it is powerful, it really has a bit of hardcore strength.

Shenzhen urban management

The 5G smart trail can connect the data of citizens in multiple stages of exercise on the designated line. After the "recognition pole" facial recognition, it can easily perform sports data analytics such as speed measurement, heat, and information display such as health guidance. In the information age, running is not pure running without spreading your legs, but to achieve "number" in "new", so that the information of runners can be seen at a glance, so that full emotional value accompanies sports. With technology and no hard work, the reason why Shenzhen Bijiashan Park has become a holy place for runners to clock in is not unrelated to a city goal.

Every city has its own colorful dreams. Forming a high-quality sports life circle with an international leading level and building it into an internationally famous sports city is the blueprint plan of Pengcheng. As a city that has hosted the Summer Universiade, Shenzhen’s sports atmosphere is "fitness every day, activities every week, events every month, and breakthroughs every year." Countless sports enthusiasts like Peng Yuyan are active in large and small parks, and they answer the realistic question of "Where to go for fitness?". Instead of fearing old and sick, it is better to spend some time on health. Shenzhen parks tell the poetry and distance in the lives of citizens.

It had to be said that Peng Yuyan ran once in Bijia Mountain Park, and the amount of information was quite large. The queue was waiting for the experience device where people interacted with AI. Because they had never seen it before, netizens joked that Peng Yuyan had "never seen the world". Behind this, the amount of "AI" in Shenzhen continued to rise steadily.

From "thousands of industries" to "thousands of households", the work report of the Shenzhen Municipal Government in 2024 mentioned that the number of urban AI + scene applications announced in Shenzhen has reached 41. When the "meridians" of the smart city are extended into the park, there will be Peng Yuyan’s first "early adopter". Let the very ordinary sports reveal the height again and again, which shows how a city is "deep AI you".

"Little’Peng ‘friend, can you tell me in advance next time you come to Shenzhen Park to run the clock in advance and meet someone by chance!" The enthusiasm for interaction between Shenzhen citizens and high-quality idols can be seen from this. Self-discipline is freedom. Peng Yuyan "changed" himself through exercise, so that thousands of ordinary people can also meet a better version of themselves through exercise. When you come to the clock in Shenzhen Park and meet "Peng Yuyan" around the corner, isn’t that you and me who exude dopamine all over? Nowadays, when exercising and leisure in Shenzhen parks, many citizens will have a deeper understanding of words related to a better life such as "health", "green" and "happiness": get moving, feel the beautiful Shenzhen with mountains and seas, and embrace a healthy and happy life.

Fan Bingbing is wearing a suit and half showing his breasts, saying that he really wants to be a mother after shooting "Zhao Gu"

    From "International Fan" to "Fan Ye", Fan Bingbing’s nickname in the entertainment industry is more and more "V5", and her dress is naturally needless to say, and every time she surprises people. At the "Zhao’s Orphan" press conference, Fan Bingbing appeared in a "pure man" dress, wearing a dark blue suit, but Fan Bingbing did not forget to show her breasts, showing off her tender side.

    Fan Bingbing, who plays Princess Zhuang Ji in "Zhao’s Orphan", is willing to commit suicide in order to save her own child. "I love this character very much, and" Zhao’s Orphan "also makes me feel the greatness of motherly love, which is really earth-shattering!" "Fan Ye" expressed his desire to be a mother more emotionally, "This play has strengthened my confidence in being a mother."

Huang Xiaoming

Huang Xiaoming mocks himself with a sluggish facial expression and openly talks about his rumored girlfriend "she’s fine"

  Huang Xiaoming spoke quite philosophically that day. He said that Chen Kaige had taught him to let go. "After filming’Orphan of Zhao ‘, I changed a lot. I let go, let go of hatred, complaints, injustice, and everything. In fact, the simpler people live, the better." Huang Xiaoming said emotionally, "There were some bad rumors before, and I have let go. If everyone still doesn’t let go, it will be a little strange."

    Immediately, the media asked Huang Xiaoming why he was so elegant and calm today. Huang Xiaoming once again laughed at himself and broke out thunder, "I was sluggish, because I filmed the whole night yesterday." Huang Xiaoming revealed that he is currently filming the movie "A Romantic Affair" in Shenzhen with his gossip girlfriend Angelababy. Speaking of the gossip girlfriend, Huang Xiaoming could not hide his smile, "She is very good!"

Ge You and Wang Xueqi broke the rumors, laughing that the two were more like husband and wife

    Since the beginning of the filming of "The Orphan of Zhao", there have been rumors that the two movie giants Ge You and Wang Xueqi have been fighting their acting skills in the play, and they are not convinced by each other outside the play. On the same day, Ge You and Wang Xueqi broke the rumors of disagreement at the scene. In this regard, Wang Xueqi said, "I like Ge You so much, and the more we shoot, the more we look like a husband and wife." Ge You said with a smile, "This is something that can be written out without a shadow, which should be regarded as a relatively low-level hype!"

    Speaking of being like a husband and wife, Ge You doesn’t change his humorous nature, "Huang Xiaoming and I are also quite like a husband and wife, I always go to his room at night to drink some wine!" Huang Xiaoming also humorously, "Then who is a man and who is a woman? Then the one without a beard on his face (implying Ge You) must be a woman!"

Chen Kaige said he was ready to be scolded, and then evaluated "not bad"

  Perhaps because "The Promise" was scolded too much, Chen Kaige has become unusually humble since the beginning. This time to promote "The Orphan of Zhao", Chen Kaige also expressed that he was ready to be scolded. His words made people feel sour, "Although everyone works hard, there will still be different voices after the release of" The Orphan of Zhao ".

    Chen Kaige’s heartfelt words drew applause from the scene. Chen Kaige also publicly thanked his wife Chen Hong: "I also want to thank my wife Chen Hong, at least [‘Orphan of Zhao’] will not make you cry secretly in the long night." Chen Kaige said that the play "Orphan of Zhao" is a story of the past, looking for harmony and understanding today, and is also a work of self-reflection. Speaking of "Promise", which received a lot of bad reviews back then, Chen Kaige said, "I think" Promise "is flawed, but overall, it is still a good movie."

The second half of the "marathon" of intelligent driving starts, and the cost of commercialization still needs to be reduced

Movies can be watched on the car window, and the windshield automatically recognizes street store information… Scenes from science fiction movies may be coming to life.
In the 2022 China International Trade in Services Fair (hereinafter referred to as the "Service Trade Fair"), the 2022 Automotive Capital Forum "Double Carbon Future, Intelligent Vehicle Acceleration" was officially held.
At present, the global automotive industry is experiencing a scientific and technological revolution unseen in a century. China’s new energy vehicles have seized the opportunity to achieve "lane change and overtake", but they still face multiple challenges when integrating with technologies such as the Internet and artificial intelligence.
Beijing News Shell Financial reporter interviewed Wu Gansha, founder of Uisi Technology, Zhang Dezhao, CEO of Smart Walker, Xu Junfeng, CEO of Future Black Technology, and other "leaders" of intelligent driving industry chain enterprises on September 1 to understand the development trend of intelligent driving and where the road to commercialization is.
"Black Technology" Revitalizes the Smart Electric Vehicle Industry Chain, Trillions of Blue Oceans Are Coming
When talking about the development of intelligent driving, the above mentioned several people introduced the "black technology" in the automotive industry chain today.
In terms of display screens, Xu Junfeng gave an example to reporters that in real life, people can enter the virtual world by wearing a pair of 3D glasses, while cars hope to turn the windshield into a screen that connects the digital world and the real world. In Xu Junfeng’s vision, the future dashboard, video conferencing, watching movies and other functions can be realized through display systems, such as the windshield in front of the driver and the window of the rear passenger.
However, according to his understanding, the above-mentioned products have been developed and mass-produced in Germany, but the effect has not yet reached the level that people expect to enter the "virtual world". He said that there are still a lot of technical problems in the virtual world that have not been solved, such as how the picture of the car is relatively still in the bumps, and whether the lidar can support the vehicle to clearly integrate the destination 100 meters away with the screen.
According to Xu Junfeng’s prediction, by 2030, people may be able to see augmented reality based on digital twins.
For example, in the future, everyone will have a digital twin of the street, and the vehicle will accurately calculate the information that the driver needs to know according to the algorithm, and project this information on the windshield, "such as the coffee shop you are used to consuming, the screen will identify the store and project the coffee price."
In terms of intelligent driving cruise systems, Zhang Dezhao introduced that today’s intelligent driving solutions mostly rely on high-precision maps, which is equivalent to superimposing human experience and intelligence into the map, marking left-turn lanes, right-turn lanes, and impassable areas.
Behind these black technologies, smart electric vehicles have actually reconstructed the automotive industry chain. The ** chain companies that are deeply tied to car companies are expected to benefit from the wave of intelligence and the rise of local technology car companies.
With the rise of smart electric vehicles, there is a strong demand for electronic accessories. From lidar, cameras, millimeter waves, and high-precision maps in induction systems, to AI chips and software in decision-making systems, to electric braking in the execution stage, and finally to intelligent cockpits, screens, and voice control in human-machine interaction needs, a large number of local enterprises have benefited from it.
The reporter combed and found that now class A shares a number of smart car industry chain companies, such as chips such as Junsheng Electronics and Zhaoyi Innovation; lidar such as Juguang Technology, Changguang Huaxin, etc.; vehicle software such as Guangting Information.
According to the analysis of the research report of Yiou Think Tank, by 2030, the scale of China’s smart transportation market will reach 10.60 trillion yuan. With the continuous improvement of the intelligent layout of the vehicle end, the road end and the cloud end, the demand for the C end will be gradually released. At the same time, with the formation of the autonomous driving market mechanism, the industrial chain has become more mature, and the smart transportation market has shown a stable growth trend.
Autonomous driving commercialization marathon, cost and technology are two major hurdles

"After people have computers and mobile phones, intelligent cars will become the third end point," Zhang Dezhao told reporters. Intelligent cars bring huge social value and have broad commercial prospects.
Zhang Dezhao further said that the intelligent driving track is a marathon track, and it is not the most important who runs the fastest, but who has the most technical reserves and can persevere until the end.
However, it will not be easy to win this marathon, as the commercialization of autonomous taxis is still being explored today.
Wu Gansha calculated an account for the reporter: if the hardware of the vehicle can be reduced to less than $10,000, the operating cost is about $5,000 per year, and the profit of the vehicle can reach 20 cents per mile, then the profit of each vehicle can be 30,000 dollars per year 150,000 miles, which is a good prospect for sustainable development of driverless taxis.
Wu Gansha founded Uisi Technology in 2016, an autonomous driving solution provider that has deployed passenger vehicles, unmanned public transportation, unmanned logistics, and smart city services, and implemented autonomous driving technology in industrial parks and other fields.
But in Wu Gansha’s opinion, what he just described is only a profitable ideal model, and the reality is still far from the above model.
Looking back on the development of new energy vehicles over the past ten years, Wu Gansha still remembers that high-resolution lidar used to cost 800,000 yuan, but now it is less than 100,000 yuan, while the cost of relatively low-resolution lidar can reach several thousand yuan. The development of the industrial chain has brought more business possibilities for enterprises, but there is still a long way to go in the future.
"The implementation of autonomous driving is a gradual process," Zhang Dezhao said. Now many autonomous driving companies have to do a lot of technical investment and research and development, and it is difficult to achieve profitability so far, and they need to consider business risks.
In addition to cost, technology is also a major challenge.
In the keynote speech of the forum, Zhang Xiaoyu, vice president of Changan Automobile, said that smart electric vehicles will become the birthplace of the next trillion-yuan market value enterprises.
From the demand point of view, the continuous advancement of users request to transform the car from a mobile machine to a model robot, which will enable the car to have a powerful sensing system, energy system and drive execution system, as well as a computing platform. Cars have eyes, ears, hearts, hands and feet, bringing similar cameras, lidar, millimeter wave radar, power battery and other industrial aggregates.
"It can be said that the core team that masters the vertical technology supply chain capability in the next ten years will have the opportunity to overtake," Zhang Xiaoyu said.
In Wu Gansha’s opinion, there are currently two main paths to the commercialization of autonomous driving. One is the gradual development of L2 autonomous driving technology based on passenger cars. In the case of a driver, L2-assisted driving technology has been given a certain fault tolerance rate and can be widely promoted.
The other is the L4 autonomous driving technology for commercial vehicles and special vehicles. In limited paths and scenarios, the road does not have too much information to process, and the speed requirements are not high, allowing for commercial operation.
In fact, these two routes also complement each other. L2-assisted driving in passenger vehicles requires continuous improvement of technology, and the operational experience accumulated in commercial vehicle L4 autonomous driving can provide reference.
Referring to the autonomous driving timetable, Wu Gansha recalled that when the company started its business in 2016, the whole industry was envisioning the implementation of L4-level autonomous driving in 2021, but this idea was too radical, and in fact it has not been fully realized now. According to his judgment, 2030 is the year when large-scale autonomous driving commercialization can be seen on public roads.
However, in recent years, our country’s autonomous driving support policies have been frequent. Recently, Chongqing and Wuhan have issued intelligent driving road test management measures, and Beijing has also disclosed that the autonomous driving demonstration zone will promote the construction of the 3.0 stage within the year, and the construction area will be expanded to 500 square kilometers in the city. The trillion-dollar blue ocean of autonomous driving is coming.

The implementation of the new car-hailing policy has reached its first anniversary, and it is urgent to improve and correct it

   The other party said that the place was spacious and they could sleep, but the result was a large truck. The weather was excellent and the road conditions were excellent.

   On July 28, 2016, the Ministry of Transport, MIIT and other 7 ministries and commissions jointly issued the "Interim Measures for the Management of Online Booking Taxi Business Services", which came into effect on November 1, 2016. Our country immediately became the first country in the world to recognize the legitimacy of online car-hailing. Now the implementation of this new policy on online car-hailing has reached the "first year". However, compared with the beginning of the break, the praise is not strong now, and various online car-hailing problems are emerging in an endless stream.

   Experts pointed out that the New Deal has clarified the legal status of online car-hailing, enabling online car-hailing to enter the stage of standardized development from brutal growth. However, new problems have arisen in the process of policy implementation, and new mechanisms need to be established for law enforcement supervision by relevant departments. The provisional implementation rules in various places still need to be continuously revised and improved.

   Taxi-hailing difficulties still exist

   In May 2010, Yidao Yongche was established, which opened the curtain on the online car-hailing industry. Since then, platforms such as Didi Dache, Kuaidi, and Uber have entered the market one after another. The strategy of "burning money and subsidies" to occupy the market has caused the online car-hailing market to grow wildly. In 2016, the introduction of the new policy on online car-hailing proposed for the first time to include Internet special cars in the management of reserved taxi cars, and specific requirements were given in various aspects such as platform online car-hailing license plates, driver qualification identification, and vehicle access.

   According to data released by the Ministry of Transport on July 28 this year, after the implementation of the new policy on online car-hailing, 24 provinces (municipalities and autonomous regions) had issued implementation opinions, 133 cities had announced implementation details, and 86 cities had publicly solicited opinions.

   Li Qiang is a driver of a company in Shijiazhuang City, and has a lot of free time due to the nature of his work. In 2015, seeing the prosperity of the online car-hailing market, he bought a BYD sedan, settled in two online car-hailing platforms, and became an online car-hailing driver. "At that time, he specially bought a small-displacement domestic car, which could earn more money at a low cost, but now it is restricted." Li Qiang told the Legal Daily reporter that his car has a wheelbase of 2,600mm and an exhaust capacity of 1.5 liters, which does not meet the requirements of Shijiazhuang City for online car-hailing.

   On July 21 this year, the "Interim Measures for the Administration of Online Booking Taxi Business Services in Shijiazhuang City" came into effect, stipulating that vehicles applying for online car-hailing business should be passenger cars with a number plate and registered in the city with more than 5 seats (including 5 seats) and less than 7 seats (including 7 seats), with a wheelbase of not less than 2675 mm and a displacement of not less than 1.8L or 1.4T. The driver engaged in online car-hailing services has a household registration at the place of service or a residence permit at the place of service.

   In comparison, the regulations of Shijiazhuang City are not strict. In Beijing, Shanghai, Shenzhen and other places, in addition to the various standards stipulated by the state, the new policy of online car-hailing also requires the driver’s household registration, license plate, model, etc., and the vehicle wheelbase and displacement requirements are higher. For example, the Beijing New Policy requires that after a private car becomes an online car-hailing, it must be changed to an operating vehicle, the driver is a Beijing household registration, the vehicle is a Beijing license plate, the displacement of a 5-seat sedan is not less than 1.8 liters, and the vehicle wheelbase is not less than 2650 mm.

   These requirements will undoubtedly many platforms net about the car driver out of the door. Some media reports, Beijing net about the car exposure draft released, a car rental company in the city has 1/3 of the driver returned the car, and even some of the vehicles have not yet expired on the lease.

   Now, Li Qiang has quit the online car-hailing industry. "Although Shijiazhuang’s official new policy has been much looser than the previous exposure draft, my car still does not meet the requirements, and I have to stop when I get checked later. I have to take exams and apply for various things. Now I don’t earn as much as before, so I simply don’t do it." Li Qiang said.

   Like Li Qiang, with the end of the transition period for the implementation of the New Deal across the country, more and more online car-hailing drivers and vehicles have withdrawn due to non-compliance with standards, causing the phenomenon of difficult and expensive taxis to take again in many cities across the country.

   According to a survey by Didi Chuxing, the difficulty of hailing a taxi in June 2017 increased by 12.4% in Beijing, 17.7% in Shanghai, 13.2% in Guangzhou, and 22.5% in Shenzhen compared with June 2016. Among the cities with reduced difficulty, Chengdu decreased by 1.8% and Sanya decreased by 1.0%.

   Liu Ting, who often travels between Beijing and Shijiazhuang, told reporters that even during off-peak hours and non-bad weather, taking a taxi outside Beijing’s CBD is likely to require queuing in the app to order a car, and Shijiazhuang is not too good. In the past, when you opened the software map, there were no more cars. "The queuing function was only launched by Didi this year. The appearance of this function is actually to admit that you have to wait longer during peak hours. This function is to retain users and let you not give up." Liu Ting said.

   Zhu Wei, deputy director of the Communication Law Research Center of China University of Political Science and Law, believes that the difficulty of taking a taxi is due to the small number of taxis, and the difficulty of taking a taxi is due to the high price. After the formalization of online taxi-hailing, the difficulty of taking a taxi is increasing. In the final analysis, the entry threshold for platforms, cars, and people is still too high.

   In response to the problem that it is difficult and expensive to take a taxi after the new policy of online car-hailing, Wu Chungeng, a spokesperson for the Ministry of Transport, said that for the difficulty of taking a taxi, the new business format of Internet + online car-hailing is standardized and continuously cultivated. Ultimately, a diverse, differentiated and quality taxi travel service system will be formed, and the market will be gradually improved to alleviate the demand for mass travel. At the same time, it is called for all localities to increase the implementation of the public transportation priority strategy.

   "Grey Area" after New Deal

   Feng Haoze (a pseudonym) is an online car-hailing driver in Shijiazhuang City. He drives a southeastern DX3 SUV with a wheelbase of 2610mm and a displacement of 1.5 liters. "I definitely don’t meet the conditions, but I don’t meet the conditions. There are only a few cars that can meet the conditions." Although Shijiazhuang’s new car-hailing policy has set a three-month transition period. The transition period has expired on October 20 this year, and the new policy has been officially implemented, Feng Haoze said he is not worried: "I have already communicated with the platform. The platform said that it is fine and will never check. They are afraid that I will not run away, so they keep giving me relief."

   When it comes to the relevant qualifications for running online car-hailing, Feng Haoze said that he has obtained the "Online Booking Taxi Driver’s License", but no matter how specific it is, he can’t explain it. "I have done everything else, and the rest should be applied by the platform. Anyway, it will not delay the sports car." Feng Haoze believes that for online car-hailing, the relevant departments will definitely not seriously investigate, "If you can’t see it outside the online car-hailing, how can you check it? Can you still find this car all over the street? Besides, as long as you check it, you will get stuck in traffic. If you really want to investigate them, you will be suspected of’fishing and law enforcement ‘, and you will be scolded to death." Feng Haoze said.

   In fact, although the new policies for online car-hailing in various places have passed the transition period and begun to be officially implemented, there are still illegal vehicles and drivers, and many platforms, drivers, and online car-hailing vehicles are walking in "gray areas" and continue to hide from regulators.

   In July this year, the media released the relevant data, our country has more than 300 prefecture-level cities, has announced the details of the reform, has been or is seeking opinions add up to only more than 210; Didi, Shenzhou two major platforms to obtain business licenses in the city were only 22, 33, the national network about the driver license only about 100,000 drivers, the national network has obtained legal identity about the car driver, less than a drop of a platform peak driver total 0.6%.

   Some experts said that the relatively large online car-hailing market, the small number of online car-hailing drivers who have obtained legal status, not only shows that the high threshold of the new online car-hailing policy has "scared away" a group of drivers, but also shows that there are some problems with the relevant approval. Among them, the most criticized is that some urban online car-hailing drivers have too difficult test propositions.

   Which dynasty did Huang Zongxi belong to? Which country is the mascot of the bat? Since the beginning of this year, some media have continuously reported some "strange" test questions in the local online car-hailing driver exam. According to reports, the Shenzhen online car-hailing driver test question bank has a total of 148 pages and more than 3,600 questions, ranging from traffic laws and regulations to human geography, place names and routes, vehicle safety, to English, Cantonese, Mandarin, and etiquette. The online car-hailing drivers who participated in the exam complained that "if you want to drive an online car, you must know astronomy and geography from above." The passing rate of the first online car-hailing driver exam in Shenzhen was only 7%.

   Wu Chungeng said in July this year that in response to this situation, the Ministry of Transport formulated relevant training materials in a timely manner and actively guided local governments to take targeted measures to create a good test preparation environment for localities and candidates. At present, the exams across the country have entered the normal track, and the test pass rate has reached 65%. Later, on September 8, the Ministry of Transport issued the "Notice on Reforming the Work Related to the Taxi Driver Qualification Examination" to simplify the test content.

   In some cities, relevant platforms have begun to gradually change the rules for dispatching orders in accordance with the local new policies, but for restrictions such as household registration and models, although some urban transportation departments have begun to investigate and punish off-site license plates or non-local household registration online car-hailing in crowded areas such as airports and railway stations, but in more places, especially in small and medium-sized cities, relevant departments have not kept up with supervision and law enforcement, making a large number of online car-hailing safe to walk in "gray areas".

   The New Deal urgently needs to be improved and revised

   "Our government is very open, and the Chinese government is the first in the world to legalize online car-hailing, which is a very big step," Liu Qing, president of Didi Chuxing, said at a forum in Dalian’s Summer Davos in June 2017. At the same time, he admitted: "But at the same time, when online car-hailing is launched, there will definitely be a gap between left and right in the implementation of various places."

   In terms of operating online car-hailing without a license, the Interim Measures of the Ministry of Communications and other seven ministries and commissions and many other cities only stipulate fines for online car-hailing platforms, without more severe penalties. Shijiazhuang, on the other hand, stipulates that if the platform company fails the assessment, it will be ordered to rectify within a time limit. During the rectification period, it can suspend the acceptance of its new vehicle and driver registration and other businesses; if it refuses to rectify or rectify and fails to meet the standards, it will be cancelled according to law and the right to operate will be withdrawn. "Reclaim the right to operate" means revoking the platform’s business license, which can be described as "one kill" for the online car-hailing platform.

   Either the relevant regulations are more relaxed and reasonable, or more stringent law enforcement supervision has become a dilemma in the implementation of the new policy for online car-hailing in some cities.

   The introduction of the new policy of online car-hailing was originally to make the online car-hailing market have laws to abide by and develop healthily. Its ultimate goal is to provide passengers with safe and high-quality services, provide citizens with more choices for travel, and make the taxi industry more standardized and efficient. However, the management of online car-hailing in some places still cannot get out of the curse of "one tube will die, and one tube will be messy" in the past.

   In Zhu Wei’s opinion, in the current online car-hailing market, the platform insists on doing this, and the online car-hailing drivers and passengers also think this is right, so there can only be a deviation between market demand and government regulations. However, for the laws and regulations that have come into effect, participants must strictly abide by them, and the industry will find some way out, and these ways will become "gray areas" between black and white. "The existence of’gray areas’ first damages the credibility of the government, and laws and regulations should be strictly enforced." Zhu Wei said that the relevant new policies should solve problems during the temporary and trial implementation process, so as to go better after a long trial.

   Some experts believe that the current restrictions on online car-hailing in some cities in terms of household registration and models are debatable. The restrictions on the household registration of online car-hailing drivers are suspected of restricting the legal labor rights of workers, and the restrictions on displacement are also contrary to green and environmentally friendly travel. "The introduction of some local online car-hailing regulations is not only to ensure travel safety and comfort, but also to give the old industry a space for compromise?" Zhu Wei said that many of the current new policies for online car-hailing deserve deep consideration and revision.

   According to relevant data, in the past 13 years, the number of taxis in the four major first-tier cities of Beijing, Shanghai, Guangzhou and Shenzhen has increased very limited, while the population size and per capita disposable income have increased significantly. Among them, the number of taxis in Beijing and Shanghai increased by only 9% and 4% respectively in 2013. The population size increased by 53% and 49%, and the per capita GDP increased by 289% and 276% respectively.

   This shows that the online car-hailing market is huge and the future development is still limitless. But in fact, since the implementation of the new policy on online car-hailing for one year, based on relevant data, only Shenzhou and Shouqi have continued to grow in the number of users of online car-hailing platforms.

   Wu Chungeng said that the Ministry of Transport will further improve and perfect relevant supporting measures and policies, give play to the role of checks and balances in the social credit system, formulate a memorandum of joint punishment for serious illegal and dishonest online car-hailing operators and drivers, establish an industry blacklist system and market exit mechanism, and continuously improve the quality and level of industry services, so that passengers can have a real sense of gain in the reform.

Tencent Jiang Jie: Tencent Hunyuan model has been connected to more than 180 businesses

Beijing News Shell Financial News (reporter Sun Wenxuan, Lin Zi) "Tencent is continuing to explore the application scenarios of large models. At present, more than 180 internal businesses have been connected to Tencent’s hybrid model for internal testing." On November 9, Jiang Jie, vice president of Tencent Group, said at the Wuzhen Summit of the 2023 World Internet Conference.

According to its introduction, as a practical-level model developed by Tencent, since its debut to the public in September 2023, the application of Tencent’s hybrid model in internal business has been continuously deepened, and at the same time, it has explored landing scenarios in various fields such as cultural communication, production efficiency improvement, and scientific and technological inclusion to explore application value.

In terms of cultural communication, Tencent’s multilingual translation and the latest Text-to-Image, Vincent 3D and other capabilities can effectively improve communication and help people from cross-cultural backgrounds communicate better. In terms of production efficiency, Tencent’s mixed model is applied in professional design scenarios, which can significantly improve the production efficiency of material creation. In terms of technology and universal benefits, Tencent’s mixed model is serving corresponding scenarios through strong knowledge reserve capabilities. For example, in the medical field, the big model can become a doctor’s little assistant, quickly understanding the needs of patients through intelligent guidance, and helping them find suitable departments or other professional medical services.

At the scene, Jiang Jie also demonstrated the Tencent Hybrid Model’s "Text-to-Video" capabilities. Focusing on keywords such as "global communication ties", "connection, efficiency and sharing" and "Belt and Road Initiative", Tencent Hybrid Model generated a video that reflects the theme of global human friendly exchanges, including high-speed rail, Guangzhou Tower, robots, Hanfu and other images.

Jiang Jie introduced that Tencent has been deeply rooted in the field of artificial intelligence for many years and has established four AI laboratories, involving multiple links from comprehensive basic research to various application development. At the same time, it has also established a laboratory matrix for cutting-edge technology exploration, covering robotics, quantum computing, life science, etc., to create a "technology engine" for the future.

Is the Milky Way a river in the sky? No, the Milky Way is…

The article comes from the official account of the Science Compound (ID: kexuedayuan)

We all know that we are in the Milky Way galaxy, but it took thousands of years for humans to correctly understand the Milky Way, and it has been less than a century since humans realized that there are hundreds of billions of galaxies outside the Milky Way that are similar to the Milky Way but not exactly the same.

So what does the Milky Way look like? What do galaxies outside the Milky Way look like? What is the process of human understanding of galaxies?

Is the Milky Way a river in the sky? No, the Milky Way is a big disk

Thousands of years ago, people had various conjectures about the Milky Way. In ancient Greek mythology, people believed that the Milky Way was paved with the milk of the diva Hera; in Chinese myths and legends, the Milky Way was a river in the sky.

It was not until Galileo pointed the telescope’s lens at the Milky Way for the first time that he discovered that the Milky Way was actually composed of countless stars. However, due to being in the Milky Way, humans still do not know the structure of the Milky Way, and what is the relationship between the Milky Way and the sun?

It was the English scientist Thomas Wright and the German philosopher Immanuel Kant who were the first to make a correct inference about the shape of the Milky Way. Wright believed that the Milky Way was flat, and that the sun was in it. Kant further conjectured on Wright’s basis that the Milky Way is a large, flat, distributed celestial system containing countless stars, which are bound together by gravity and revolve around a center like the solar system.

Imaginary map of the structure of the Milky Way (facing)

In the late 18th century, British scientist Herschel gave the first quantitative estimate of the shape of the Milky Way. He used a homemade telescope to count the stars in the Milky Way, and for the first time used observational data to prove that the Milky Way is a flat shape.

Herschel’s quantitative estimate of the shape of the Milky Way

Today, we have a more detailed understanding of the structure of the Milky Way. The Milky Way is roughly a flat disk, about 100,000 light-years in diameter and about 10,000 light-years thick. There are about 300 billion stars distributed on the disk. Among them, the sun is about 26,000 light-years away from the center of the Milky Way. In addition, there is a rod-shaped structure at the center of the galaxy, with several spiral arms extending at each end of the rod. At the center of the galaxy lives a black hole about 4.30 million times the mass of the sun.

What’s outside the "silver plate"? Short sticks, lenses, football…

Through telescopes, astronomers saw stars in the Milky Way, and at the same time, they observed many nebulous objects called nebulae. In 1780, the French astronomer Messier published a table of nebula clusters containing 110 celestial objects.

Is the nebula, especially the spiral nebula, in the Milky Way or outside the Milky Way? On this question, in 1920, the National Academy of Sciences held what is historically known as the "great debate". In this debate, Shapley argued that the Milky Way is huge, the spiral nebula is within the Milky Way, and the Milky Way is the whole universe; the other side, Curtis, believed that the Milky Way is not the whole universe, and those nebulae are outside the Milky Way. Neither side convinced the other in this debate, but both pointed out that the measurement of distance and scale is the key to solving this problem. In 1923, Hubble observed the Andromeda Nebula (M31) with the Hooker Telescope, using distance measurements of Cepheid variable stars in M31 to prove that the distance of M31 was much larger than the scale of the known Milky Way.

After Hubble discovered and certified extragalactic galaxies, he further conducted a systematic study of the morphology of extragalactic galaxies. Hubble found that galaxies with different shapes can be divided into three categories, elliptical galaxies, spiral galaxies, irregular galaxies, and there is also a transition type – lenticular galaxies. This classification method can be summarized by the Hubble tuning fork diagram

Hubble tuning fork diagram (Image source: Wikipedia)

The first type of elliptical galaxies, such as galaxies with a perfectly circular or elliptical shape, highly concentrated brightness distribution, and no obvious substructure, are represented by the English letter E.

Elliptical galaxies (Image source: Wikipedia)

The second type, the spiral galaxy, has a distinct spiral structure in its shape, which is recorded as S in English. This type of galaxy has a bright, unstructured bulge at the center. In addition, there is a type of spiral galaxy with a short bar structure running through the bulge at the center, which is recorded as a barred spiral galaxy (SB).

The third type, irregular galaxies, are galaxies with an irregular shape without obvious spiral arms, nuclei, and other structures, called irregular galaxies, which are denoted as Irr.

A lenticular galaxy is a galaxy between an elliptical galaxy and a spiral galaxy, denoted S0. This galaxy has a disk-like structure, but no obvious spiral arms, and is generally lenticular. If there is a rod-like structure in the center, it is called a rod-lensed galaxy, denoted SB0.

Lensed galaxy NGC 2787 (Image source: Wikipedia)

The Hubble classification of extragalactic galaxies is based on two-dimensional images. What do these galaxies look like in real three-dimensional space?

It’s thought that elliptical galaxies actually look like a football, so if we look at them from the tip, they look like a perfect circle, if we look at them from the other side, they look like ellipses, whereas spiral galaxies actually look like plates, and again, depending on where we look, spiral galaxies look very different.

Conclusion

Since Hubble proved that galaxies are "islands" in the universe, astronomers have been studying the details of how galaxies form and evolve in the universe, and using them to uncover the mysteries of the universe. As the overall picture of galaxy formation and evolution is built, more and more mysteries are being solved. The mysteries of galaxies are attracting generations of astronomers to study more deeply.

Harbin says no to taxi charging!

  

The taxi in the online leaked video

The taxi in the online leaked video

       CCTV News(Reporter, Li Wenwen) A taxi from the airport to the city originally did not exceed 131 yuan, but when six Guangzhou students came to Harbin for tourism, they were charged 550 yuan each for two taxis. After the incident was exposed, on December 15, the tourism department of Harbin launched the first compensation mechanism of the Tourism Integrity Fund, which paid students who suffered slaughter in advance.

  On December 14, six university students from Guangzhou took a flight to Harbin for a tour. The first stop was planned to be Central Street, a famous scenic spot in Harbin. The six people took two taxis from Harbin Taiping International Airport and were charged 550 yuan each after arriving at their destination. The ticket provided by the driver showed that the amount was 19 yuan. According to the taxi software, the distance was less than 40 kilometers, and the estimate did not exceed 131 yuan. The cost of 550 yuan is equivalent to arriving in Changchun City, Jilin Province.

  The student who was slaughtered later called to report the incident and exposed the incident online. In response to the students’ questions, a taxi driver said, "It can’t be wrong, don’t worry." "Regular taxis can’t pit you, they can’t hurt you."

  At 15:00 on December 15, the tourism department of Harbin City called some students to express their sincere apologies for their experience in taking a taxi in Harbin, and immediately launched the advance compensation mechanism of the Harbin Tourism Integrity Fund to make advance compensation. The tourism department of Harbin City reminded that the majority of tourists in the process of tourism in Harbin should immediately call the complaint number 0451-12345 if they encounter acts such as bullying and slaughtering customers whose legitimate rights and interests are infringed. The relevant departments will deal with it as soon as possible and effectively safeguard the legitimate rights and interests of tourists.

  In addition, the Harbin Municipal Transportation Bureau, after conducting an investigation and verification with the Daoli District Transportation Bureau, where Central Street is located, made the following decisions on the involved enterprises and drivers: revoke the right to operate the car involved and the license of the taxi driver involved.

  After being punished by the transportation department, the Harbin Daoli Public Security Bureau, in accordance with Article 49 of the Public Security Administration Punishment Law, gave 15 days of administrative detention to suspected fraud suspects Zhang and Fan and was fined 1,000 yuan.

  In response to the problems that have always existed in the taxi industry in Harbin, the Harbin Municipal Party Committee and Supervision Committee held a special project meeting on December 10 to crack down on "black taxis" and strictly investigate "umbrella companies". The meeting pointed out that the current Harbin is ushering in the peak period of ice and snow tourism, and tourists from all over the world are coming. The transportation department should carry out special projects to rectify the illegal operation of "black taxis"; the Municipal Disabled Persons’ Federation should review the handling of licenses for illegal operators with disability certificates; the Municipal Commission for Discipline Inspection and Supervision should seriously investigate and punish the illegal operation of taxis as "umbrella companies" and government officials.
