Nuclear Watch ｜ The United States proposes to freeze its nuclear arsenal. Is there any hope for the renewal of the US-Russia strategic arms control treaty？

Recently, some media reported that the United States and Russia reached an agreement in principle to freeze their respective nuclear warhead inventories, and the United States also hopes to set an upper limit on the number of nuclear warheads. However, Russian Deputy Foreign Minister Ryabkov responded on 14th that Russia could not accept the US position on freezing nuclear arsenals. What is the purpose of the United States to set a ceiling on the number of nuclear warheads? What impact will this move have on the future fate of the new Strategic Arms Reduction Treaty?

American intercontinental missiles are equipped with nuclear warheads.

During the Cold War, there was a nuclear arms control with a ceiling.

It is no stranger to voluntarily freeze the size of nuclear arsenals and set a ceiling. This kind of move occurred during the Cold War between the United States and the Soviet Union. The first stage of negotiations on the limitation of offensive strategic weapons (SALT-I) between the United States and the Soviet Union contained the content of limiting the upper limit of their respective strategic weapons. For example, the United States has 1,054 intercontinental ballistic missiles (when SALT-I negotiations were concluded), and the Soviet Union has 1,398 intercontinental ballistic missiles, which are limited to 1,618. There are 600 submarine-launched ballistic missiles in the United States, limited to the upper limit of 710, while the Soviet Union has 950, and the upper limit is 950. There are 37 strategic missile nuclear submarines in the United States, and the upper limit is limited to 44, while the Soviet Union has 63. Instead, it is necessary to cut one and limit it to 62. The United States and the Soviet Union did not impose restrictions on strategic bombers. At the same time, the negotiations between the United States and the Soviet Union at this stage also restricted and restrained strategic defensive weapons, and the ABM Treaty signed during the SALT-I negotiations made some positive contributions to maintaining strategic stability between the United States and the Soviet Union.

However, SALT-I is not a disarmament agreement in a positive sense. The United States and the Soviet Union aim at limiting each other’s arms expansion, with emphasis on control and restriction. As far as the United States is concerned, the achievement of SALT-I provides space for the United States to spare time and energy to improve the quality level of strategic deterrence. For example, the existing Trident missile and B-1 bomber in the United States are all developed during the relaxation period after the conclusion of SALT-I by the United States and the Soviet Union. As far as the Soviet Union is concerned, the number of nuclear weapons in the Soviet Union in the late 1960s was basically equal to that in the United States, and the use of the salt-I relaxation period can also improve the quality of nuclear weapons for the Soviet Union and accumulate capital for future confrontation with the United States.

During the three years from 1977 to 1979, the United States and the Soviet Union continued to negotiate the second stage of strategic offensive arms limitation (SALT-II). The main purpose of SALT-II was to implement the temporary agreement and related temporary constraints reached in SALT-I negotiations before, and form a real strategic arms limitation treaty. The negotiation result was that the United States and the Soviet Union signed the Treaty on Strategic Offensive Arms Limitation. As can be seen from the name, the arms control agreement reached by the United States and the Soviet Union at this stage is still based on restrictions, rather than real disarmament and reduction.

For example, according to the content of the treaty, when the United States and the Soviet Union negotiated, the United States owned 2,142 strategic projection weapons, including land-based intercontinental ballistic missiles, sea-based submarine-launched ballistic missiles and strategic bombers, and the Soviet Union owned 2,318, and the United States and the Soviet Union were unified and limited to 2,250. The emergence of multi-warhead technology was the focus of technical attention between the United States and the Soviet Union in that period. The land-based multi-warhead missiles and sea-based multi-warhead missiles of the United States and the Soviet Union have also been restricted. At the time of negotiation, the United States had 1,046 land-based and sea-based submarine-launched missiles capable of carrying multiple warheads, and the Soviet Union had 588 land-based and sea-based submarine-launched missiles capable of carrying multiple warheads, which was limited to 1,200 according to the treaty. The technological capabilities of the United States and the Soviet Union, including the number of nuclear weapons, reached a peak in the Cold War before and during the SALT-II negotiations. The two countries were aware of the restrictions on strategic offensive weapons, but this restriction set an upper limit. Specifically, both SALT-I and SALT-II set an upper limit on the number of strategic offensive weapons of the other side, such as multi-warhead missiles. The upper limit set by SALT-II gave the Soviet Union room to continue to develop and increase multi-warhead missiles.

Russia has accelerated the modernization of nuclear weapons in recent years. The picture shows the newly developed "sarmat" liquid intercontinental missile.

What are the considerations for the United States to set a nuclear ceiling?

There are certain historical reasons for the SALT-I and SALT-II negotiations between the United States and the Soviet Union during the Cold War. For example, the United States was mired in the Vietnam War in the 1960s and 1970s, and its domestic economy was dragged down to some extent. In order to confront the United States in the Cold War, the Soviet Union neglected the livelihood economy, and the problems of the livelihood economy emerged in the early 1970s. In 1971, the ninth five-year plan for the Soviet economy formulated at the 24th Congress of the CPSU was not completed, and the production efficiency of consumer goods for the people’s livelihood was low. The domestic economic situation of the United States and the Soviet Union is not optimistic, and the two countries need to reduce the negative impact of the arms race on the economy. In addition, the technical level of strategic weapons of the two countries has been continuously broken, and both countries have strategic intentions to restrict the development of their opponents. However, the strength of the two countries is equal, and it is difficult to reach a mutually acceptable reduction agreement in a short time. Therefore, under the circumstances that it is difficult to achieve arms reduction in a short time and the prospect is uncertain, setting an upper limit and voluntarily freezing can not only achieve some restrictions on the other side, but also leave room for the development and operation of armaments. Restricting nuclear armaments has become the main manifestation of nuclear arms control behavior in the pre-cold war period between the United States and the Soviet Union.

Salt-I and Salt-II didn’t help to reduce armaments, but to a certain extent put a brake on the strategic arms race between the United States and the Soviet Union. The confrontation between the United States and the Soviet Union still drives them to expand their strategic arms capabilities. It was not until the middle and late 1980s that the nuclear arms control between the United States and the Soviet Union began to transform into real reduction.

Now the United States and Russia are discussing freezing the number of nuclear warheads, and the United States proposes to set the upper limit of nuclear warheads, which is actually similar to the consideration of the United States and the Soviet Union during the Cold War. On the one hand, both the United States and Russia have increased their investment in the development of strategic weapons in recent years. A series of new types of strategic weapons have been put into use in Russia, and the United States is also upgrading the modernization level of its nuclear arsenal and implementing nuclear expansion. The continuous withdrawal and breach of the contract by the United States has also undermined the strategic stable relationship between the United States and Russia. The prospect of the new Strategic Arms Reduction Treaty is worrying. Since it is difficult to reach an effective consensus on further reductions in the future, trying to freeze and set a ceiling is a move to build minimum mutual trust and ease the tension in strategic competition between the United States and Russia.

In addition, the US election is approaching. If the Trump administration throws out the idea of limiting and freezing the number of nuclear weapons at this time, it does not rule out that it is a consideration to alleviate its overly radical unilateralist security policy in the past four years and improve the image of Trump’s arms control saboteur. It is less than a month before the US election. If Trump wins the re-election, the upper limit of the number of nuclear weapons between the United States and Russia envisaged by the United States will actually provide flexible space for the United States to upgrade its nuclear arsenal and adjust the number of different nuclear weapons in the future. This is quite similar to the fact that although the United States and the Soviet Union conducted nuclear arms control in the middle period before the Cold War, the number of nuclear weapons became more and more controlled, and the nuclear weapons and equipment became more and more advanced. The United States intended to set a ceiling, which was tantamount to providing development space for the US nuclear arms expansion in disguise.

With the approach of the general election, the policy ideas of the two presidential candidates in the United States have gradually become clear, and Trump and Biden have different attitudes towards arms control. Trump, as always, emphasized "withdrawing from the treaty" for nuclear arms expansion, while Biden said that if elected, he would extend the new Strategic Arms Reduction Treaty, reconsider returning to the Iranian nuclear deal in full compliance, shrink the Trump administration’s nuclear arms expansion plans, such as developing new nuclear warheads and new nuclear vehicles, and carefully consider the role of nuclear weapons. No matter who dies in the final US election, whether Trump continues to spoil the game or Biden makes up for it, the negative impact of the Trump administration’s destruction of international social security and stable relations between major powers in the past four years will be difficult to eliminate in a short time.

Movie Channel May 4th Film List ｜ Play the Song of Youth and Contribute to Youth.

Special feature of 1905 film network "China youth are young people with lofty ideals and ambitions! China youth are young people with deep feelings for home and country! China youth are young people with great creativity! Regardless of the past, present and future, China youth has always been the vanguard force to realize the great rejuvenation of the Chinese nation! "


Today is the 103rd May 4th Youth Day. This year, we also celebrate the centenary of the founding of the Communist Youth League of China.


On this special day, the film channel will broadcast four films filled with the youth of their parents.Let’s go back to that era and look for those inspiring shining footprints.

01

Song of youth

At 9: 40am on May 4th, the film channel broadcasted the dazzling revolutionary literary classic Song of Youth in China’s film history, revisiting the revolutionary wave that stirred up in the 1930s.



The color film Song of Youth, produced in 1959, is adapted from the novel of the same name by Yang Mo, a female writer who has been translated into more than 20 languages and has attracted much attention at home and abroad.


With the historical period from "September 18th" to "December 9th" as the background and the student movement as the main line, the film tells the story of young intellectuals in China, represented by young woman Lin Daojing, who made unremitting exploration, went through many twists and turns and finally embarked on the revolutionary road in order to resist Japanese imperialist aggression and save the motherland in distress.



This surging film of the times is not only touching in story, but also unique in filming.


In the use of lens language, Song of Youth, contrary to the habit of using relatively static screen lenses in the 1950s, boldly and appropriately used a lot of push-pull and zoom lenses to express the majestic momentum of the revolution more vividly.



At the same time, "Song of Youth" used a lot of revolutionary songs that were deeply rooted in people’s hearts. Popular songs such as "On the Songhua River", "Song of Saving the Nation" and "Flowers in May" pushed the mood of watching movies to one climax after another, and deeply sympathized with the feelings and revolutionary enthusiasm of Chinese sons and daughters.



They burned the mottled old shadows of youth for the revolutionary cause, and now they are vaguely moving.


02

Forever a teenager

　"Teenagers are not afraid of long years, and they are still teenagers after a hundred years of wind and rain." May 4th.At 15: 15, the movie "Forever Teenagers" is set in the Anti-Japanese War era in the 1920s, focusing on five ideal students, and tells the story of young college students with ideals struggling for their beliefs in the constant social changes in the early days of the founding of the Party in communist party.



In order to present a true sense of time and life, the creative team successively traveled to nine provinces and cities such as Jiangsu, Guangdong, Fujian, Shanghai, Zhejiang, Shandong, Liaoning, Heilongjiang, Shaanxi, etc., and reproduced historical scenes such as the birth of the Communist Party of China (CPC), the workers’ movement in the early days of the founding of the Party, the first cooperation between the Kuomintang and the Communist Party, the Northern Expedition, the failure of the Great Revolution, and the establishment of revolutionary armed forces of workers and peasants to the maximum extent.



The director said: "In the movie, a group of ordinary students chose the Communist Party of China (CPC) in the ideological trend and laid the foundation stone for the new China Building. I’ve been thinking about it and want to present such a story. I am going to digest a lot of historical materials, look for moving points in Qian Qian’s thousands of stories and historical events, and mix them with processing and creation. "


This group of college students is a group of people who dared to act in those days: Wen Ting is full of iron, Feng Jianxing is full of wisdom, the leopard is awkward, the old warrior is mature and calm, and the soybean milk is brave and fearless … …



Although they have different personalities, their fiery youth and burning passion are the same under the special historical background. No matter how tortuous the revolutionary road is, they still stick to their original intentions and embrace regretless youth.

03

The Sacrifice

The great spirit of resisting U.S. aggression and aiding Korea forged in the War to Resist U.S. Aggression and Aid Korea is precious spiritual wealth, which will inspire the people of China and the Chinese nation to overcome all difficulties and obstacles and all powerful enemies.


The Sacrifice, which was broadcast at 17: 30 on May 4th, focused on the engineering soldiers outside the frontal battlefield in jincheng battle in 1953, and tried to truly present that little-known history.



There are not many movies describing the theme of engineers. The Sacrifice looked back at the "pioneer of the army" behind the bridge of heroes, which could not be broken and bombed, in order to ensure logistics supply and transportation and defend the traffic fortress.



"We didn’t get bayonets in this battle, and we didn’t kill the enemy ourselves, but we know the meaning of our work: we ensured the victory of the battle." Zhang Zhenzhi, the "engineering hero", was the actual commander who repaired and protected the Yanli Bridge in Jingangchuan.



"Why is the battle flag picturesque, and the hero’s blood dyed it red? Why is the spring always there, and the hero’s life blooms?"


They launched a life-and-death relay for defending the country and defending the country, and used their lives to open up an "exploding steel transportation line", which provided a strong reliance for the frontal battlefield and exchanged peace and development for generations.



The Sacrifice has opened up a big picture from a small viewpoint, which shows us the brave and lovely young people in China outside the front line and their great spirit of "not afraid of sacrifice, defeating the strong with the weak".


04

The Pioneer

At 19: 50 on May 4th, The Pioneer walked into the life of Li Dazhao, a "great Marxist", which brought us back to the awakening era of being born to death.



The May 4th Movement in 1919, the Covenant of "South Chen Bei Lee" and the strike of Kailuan Minmetals Alliance … …


The film takes the 38 hours before Li Dazhao died heroically as the breakthrough point. In flashbacks, several important moments that Li Dazhao explored hard for the road of China are constantly flashed back, which uniquely weaves his life of leading a group of revolutionaries to actively run and fight for national salvation.



With a romantic lens, The Pioneer presented the audience with not only a magnificent history under a wide-angle lens, but also the mission and dream of the revolutionaries a hundred years ago.



"I wish my dear youth, born in youth and died in youth, born in youth and died in youth. Go ahead without considering the future, turn your back on darkness and turn to light, advance civilization for the world and create happiness for mankind. With my youth, I will create a family of youth, a country of youth, a nation of youth, a human being of youth, a planet of youth and a universe of youth, so that I can enjoy my endless life. "


Li Dazhao’s article "Youth" published in "New Youth" in 1916 was about the young people who fought for the revolution and himself.



It is their revolutionary pride that makes us believe that victory will surely come.



Looking back on the century-old history, countless young people have turned their flesh and blood into the cornerstone of progress, and struggled on the road of building a new China with firm faith and no regrets.


Nowadays, the young people of our new era are also inspired by their parents’ century-old struggle history, and write a beautiful chapter of the new era with the passion of youth.


On May 4th, the film channel will continuously broadcast the revolutionary historical film Song of Youth and Forever a Teenager, which shows the high-spirited youth of my father, The Pioneer, The Sacrifice.


Let’s go with our dreams in Do not forget your initiative mind!

Extended range car： an innovative journey from germination to popularity

The development of automobiles.

In today’s era of continuous change and innovation in the automobile industry, automobiles, as a unique type, are gradually emerging in the market. It not only has the advantages of environmental protection, but also overcomes the endurance anxiety of pure electric vehicles to a certain extent, which has become the focus of many consumers and automobile manufacturers. Let’s review the development of automobile together and explore its trajectory from birth to gradual rise.

First, the origin of the car. The concept of automobile can be traced back to the early 20th century, when it was in a stage of rapid development, and people put forward higher requirements for the performance and reliability of automobiles. Some engineers began to think about how to improve the fuel economy and environmental protection of automobiles without sacrificing performance, so the new concept came into being.

Early cars mainly added a battery pack on the basis of traditional fuel vehicles, which were driven by electric motors and mainly used to charge batteries. Although this design concept has improved the fuel economy of the automobile to a certain extent, it has not been widely used because the battery technology and motor technology at that time were not mature enough and the performance and reliability of the automobile were not ideal.

Second, the tortuous road of technological development. In the following decades, the development of automobile experienced a long and tortuous road. With the outbreak and the continuous improvement of environmental awareness, people’s demand for new energy vehicles is increasing. However, due to technical and cost constraints, pure electric vehicles and hybrid electric vehicles can not fully meet the market demand for a long time.

During this period, some car manufacturers began to pay attention to cars again and invested a lot of resources in research and development. By constantly improving battery technology, motor technology and engine technology, they have improved the performance and reliability of automobiles. At the same time, the government has also issued a series of policies to support the development of new energy vehicles, providing a good policy environment for the development of automobiles.

Nevertheless, the performance of cars in the market is still unsatisfactory. On the one hand, due to the relatively complex structure and high cost, it is difficult to compete with traditional fuel vehicles and pure electric vehicles. On the other hand, consumers’ awareness and acceptance of cars are relatively low, and many people have doubts about the performance and reliability of this new type of car.

Third, the rise in recent years. Since the 21st century, with the rapid development of battery technology, motor technology and electronic control technology, automobiles have ushered in new development opportunities. Some emerging automobile manufacturers began to take automobiles as their main product direction, and launched a series of competitive models.

Take it as an example, its ideal L series models have achieved great success in the market. These models adopt advanced extended range technology, and the comprehensive cruising range can reach thousands of kilometers, effectively solving the problem of users’ endurance anxiety. At the same time, they also have spacious and comfortable interior space, rich intelligent configuration and excellent dynamic performance, which are favored by many consumers.

In addition to LI, the car series, such as car, also performed well in the market. The appearance of these models not only enriches the product line of automobiles, but also improves consumers’ awareness and acceptance of automobiles.

Fourth, the technical characteristics of the car. The core technology of automobile is range extender, which is usually composed of engine, motor and motor. The function of the range extender is to charge the battery when the battery is low and extend the cruising range of the vehicle. Different from the traditional fuel car, the engine of the car does not directly drive the car, but converts mechanical energy into electrical energy through the generator, and then the electric energy is converted into mechanical energy by the motor to drive the car.

This design concept makes the car have the following technical characteristics:

→1. Long cruising range: Due to the existence of the range extender, the car can charge the battery when the battery power is insufficient, thus extending the cruising range of the car. Compared with pure electric vehicles, cars have a longer cruising range and are more suitable for long-distance travel.

→2. High fuel economy: under urban working conditions, cars can mainly rely on battery to achieve zero emissions; When driving for a long distance, the range extender can work in the most economical condition to charge the battery and reduce fuel consumption.

→3. Good driving experience: Cars are usually driven by electric motors. The characteristics of the electric motors make the vehicle have a quick dynamic response and a smooth acceleration when starting, and there is no sense of shift frustration of traditional fuel vehicles.

→4. Good environmental protection performance: Although the car needs to consume fuel during use, its engine is mainly used to charge the battery instead of directly driving the vehicle, so its emission is relatively low and its environmental protection performance is better.

V. Future development prospects. With the continuous progress of technology and the continuous reduction of cost, the future development prospect of automobiles is very broad. On the one hand, with the continuous development of battery technology, the energy density and cruising range of batteries will be continuously improved, which will further improve the performance and competitiveness of automobiles.

On the other hand, as the government’s support for new energy vehicles continues to increase, cars will be expected to get more preferential policies and subsidies to reduce consumers’ car purchase costs. In addition, with the increasing awareness and acceptance of new energy vehicles by consumers, the market demand for automobiles will also increase. In the future, automobiles are expected to become an important part of the new energy automobile market and contribute to promoting the automobile industry.

In a word, automobile, as a new type of new energy vehicle, has experienced some twists and turns in its development process, but it has gradually risen in recent years and shown great development potential. It is believed that in the future, with the continuous progress of technology and the continuous maturity of the market, automobiles will play a more important role in the automobile industry.

Huang Xiaoming Encyclopedia updates Ye Kecheng’s ex-girlfriend’s love affair.

Huang Xiaoming, known as the "goddess of youth" in the entertainment circle, has attracted countless fans with his face value, acting skills and wealth. Ye Ke is a online celebrity with fair skin and long legs. She runs a women’s clothing business and has good economic conditions. When they came together, it should have been a perfect match.

Huang Xiaoming encyclopedia updates Ye Kecheng ex-girlfriend

Looking back on their love course, from being photographed by the media traveling and having dinner together to the official announcement of their love affair in Huang Xiaoming on September 19th, 2024, this relationship has always been the focus of the entertainment circle. At that time, Huang Xiaoming showed his love generously, and Ye Ke was full of happiness, as if the whole world were blessing them.

However, there is a huge storm behind happiness. First came the news that Ye Ke asked Huang Xiaoming for a sky-high breakup fee, and then came all kinds of negative news about Ye Ke, such as plastic surgery, divorce, attending a celebrity training class, etc. These rumors made her image plummet and Huang Xiaoming fall into the whirlpool of public opinion.

Some comments made by Ye Ke in the live broadcast also caused controversy, such as describing the taste of cake with clip sound, voicing that Wu Bai’s song was "obscene" and saying that the song "You will marry me today" was "shameful". Netizens expressed their incomprehension and questioned why Huang Xiaoming chose such a "wonderful work".

Nevertheless, Huang Xiaoming seems to turn a blind eye to Ye Ke’s behavior. Some people speculate that this may be his acquiescence, because Ye Ke, as a online celebrity, has brought huge traffic, and if there is traffic, there is a chance to realize it. However, Ye Ke’s emotional intelligence and connotation problems caused her to offend many people, and even Huang Xiaoming’s popularity was affected.

Recently, Huang Xiaoming deleted Weibo, who had an affair with Ye Keguan, which triggered a heated discussion among netizens. Some people speculated that the two had broken up, while others criticized Huang Xiaoming for not taking responsibility. Huang Xiaoming’s operation this time is really confusing. Is it true love or "killing pigs"? The plot reversed too quickly.

However, the emotional affairs in the entertainment circle are always full of variables. Maybe they are just having a little trouble, and they will make up in a few days. After all, separation and integration are commonplace in the entertainment industry.

Huang Xiaoming, as a public figure, should be more cautious in dealing with his emotional problems, so as not to let his fans worry about it. Since Ye Ke chose to be with Huang Xiaoming, he should also pay attention to his words and deeds, and don’t give her boyfriend any trouble.

This drama is not over yet, and maybe there will be more reversals and surprises. After all, the script of the entertainment circle will never be guessed. I hope Huang Xiaoming and Ye Ke can handle their emotional problems well and don’t let the fans down. As an audience, we should also be rational and not blindly follow the trend or make personal attacks on the parties.

Jinan transportation department issues risk warning for online car-hailing industry

Recently, many places across the country have issued warnings about the saturation of online car-hailing, and Sanya City in Hainan Province has decided to suspend the business of accepting online car-hailing business licenses and transportation licenses. Previously, the transportation department of Jinan City also issued a risk warning for the online car-hailing industry to remind employees. In the "second half" of the development of online car-hailing, what is the industry environment in Jinan? What changes have taken place in the market?

The efficiency of individual receiving orders has decreased, and one driver serves multiple "owners".

"Now the orders are not as good as before, the big orders can’t be received, and the small orders are tossed back and forth." In Jinan, Wang Xingyi has been working as an online taxi driver for four years, and he has run for more than 1,000 days from part-time to full-time. "In the first year, I worked part-time, and the number of orders was OK, especially on weekends, and I almost never stopped receiving orders." Wang Xingyi worked part-time, and the monthly flow was more than 8,000 yuan, so the second year he ran a full-time online taxi. What he didn’t expect was that with the passage of time, there were more and more Internet taxi platforms, and the number of online drivers was increasing day by day. The most obvious feeling was that the number of travel orders received was not as good as before.

At 10 am on the 11th, the reporter called a taxi from Jinan City Long-distance Bus Station through Autonavi Map, Meituan and other platforms. On the interface of the aggregation platform, there are nearly 100 taxi-hailing platforms in the economy category alone. After calling at the same time, drivers will soon take orders. "From the aggregation platform, you can see how many online taxi-hailing cars are running on the road in Jinan." Entering the car of Mr. Li, the driver of the timely car, the first thing that came into view was the three mobile phones in front of him. "Now it is not as good as before. There are too many platforms, and the passenger flow is scattered. Only one platform is attached to it, and the number of orders is not large. Multiple platforms have multiple opportunities." Mr. Li used "the east side is not bright and the west side is bright" to describe this operation method.

The phenomenon of online ride-hailing drivers docking to multiple platforms has become more common in recent years. The same car has more than one "owner" serving the same driver. By docking on multiple platforms, in addition to improving one’s order volume, it can also increase the probability of receiving large orders. "During peak periods, there are too many orders to start, which is not cost-effective and time-consuming. Sometimes it takes half an hour to block in the urban area," Mr. Li said. When multiple platform orders come in, you may encounter medium and long-distance orders to the airport or peripheral areas and counties.

Recently, a video of an online car-hailing driver’s car full of mobile phones receiving orders leaked out on the Internet. Multiple brackets were laid in the car, with eight or nine mobile phones on them, each mobile phone displaying a real-time picture of receiving orders from a platform. "In the past, there was a colleague who hung up on seven platforms at the same time, and the order came in at the same time, and it was all beeps," Mr. Li said. There is still an influx of people pouring in when the flexible market for online car-hailing is saturated

In recent years, there have been more and more drivers on online car-hailing platforms, and today, when the capacity is basically saturated, there are still many newcomers joining. "From the perspective of practitioners, the threshold for online car-hailing is low, the work is flexible, and everyone’s impression of online car-hailing drivers can earn more than 10,000 yuan a month by running around casually," Mr. Li believes.

"After the original job was sluggish, I wanted to change industries. After comprehensive consideration, I still think online car-hailing is more suitable." The reporter’s investigation found that there are not a few online car-hailing drivers who have the same opportunity as Mr. Li. The entry threshold is not high and the working method is relatively flexible, which makes online car-hailing a job option for many people.

For some young people, online car-hailing is also a "way out" for employment. "In the first year of graduation, I didn’t find my favorite job, so I thought about driving online car-hailing for a period of time, and I had a source of income. Later, I got used to it, and I have been doing it until now." Zhang Bo took running online car-hailing as his temporary job after graduating from university, which was also the fastest job he could find. "At that time, the traffic was still relatively large, so I didn’t have to worry about the list. After my college classmates at the time found out, some people also joined or worked part-time."

The fast and convenient way to call a car has made online car-hailing the first choice for many people to travel and take a taxi. The huge potential market development space at the beginning has attracted a batch of practitioners. Between the ages of 20 and 50, people in every age group are engaged in the profession of online car-hailing drivers.

"Every morning at 6 am, pick up the car and go home at 5 pm, there are no restrictions on the company’s various regulations. And in the two years when the market was good, we did make money." Zhang Bo said that in the first two years, it was very easy to take dozens of orders every day, and you could run more than 100 yuan in an hour. When you are tired, you can take a day or two off. For college students who have just left school and middle-aged people with a lot of family affairs, this relatively flexible work has a greater appeal.

In the interview, some online car-hailing drivers made a calculation to the reporter. In the first few years of the booming online car-hailing market, the average daily flow was around 800 yuan, but now the daily flow is less than 400 yuan. "After the Spring Festival, the cultural tourism market has recovered one after another, and the urban traffic counting has increased, but because there are many online car-hailing platforms and drivers, the passenger flow to their hands is not as high as expected." Mr. Jia said that some platforms have incentive mechanisms for drivers. There are rewards similar to "rushing orders" for receiving more orders. Coupled with the current decline in efficiency, many full-time online car-hailing drivers have increased their running time and saturated orders. Mr. Jia believes that the usual passenger flow is limited, there are more and more drivers, and everyone’s running time is about 10 hours a day, which has exacerbated the competition. My brother "switched to" some traditional taxis on the online car-hailing network without carrying

Jinan Urban and Rural Transportation Bureau in the network about car industry risk warning released a set of data, as of the end of March this year, Jinan registered a total of 69 network about car platform enterprises, registered network about car 17,800 vehicles, get the network about car qualification certificate driver 35,900. Affected by the network about car and the number of employees increased sharply and rapidly, according to statistical data estimates, the current network about car bicycle daily average number of orders less than 10 orders.

In recent years, the number of private cars in Jinan’s urban area has also been increasing, and the two types of vehicles are intertwined, which has a certain impact on road traffic during peak hours. Jinan City adheres to the basic idea of giving priority to the development of urban public transportation, developing taxis in a moderate and orderly manner, and optimizing the urban transportation structure for urban transportation layout. In the case of car-hailing saturation, there are still many people flooding into the market, which also diverts the flow of urban public transportation.

The reporter found that in addition to having a certain impact on urban traffic, the impact of online car-hailing on traditional cruise taxis is also very large. "In the first few years, when there were not so many platforms, online car-hailing ushered in a dividend period, and many people used it as a part-time means." The person in charge of a taxi company in Jinan told reporters that whether it is taxis or online car-hailing, it is a supplement to urban public transportation. Now residents are more inclined to ride-hailing than traditional cruise taxis, which allows online car-hailing to have a large market development space, but the space is ultimately limited. With the increase of platforms and the increase in the number of drivers, the market began to saturate.

The person in charge admitted that the online taxi-hailing industry has also attracted some traditional cruise taxi practitioners. Some taxi drivers do not renew their contracts with taxi companies after the contract expires, but choose online taxi-hailing instead. "Joining or renting a car is a more common way to recruit online car-hailing. It is more convenient for drivers to join, and the operation model is relatively flexible. In the past few years, the cruise taxi industry has lost a lot of drivers."

Jinan City’s online taxi booking industry risk warning notice also pointed out that at present, some online car-hailing platform companies are idle due to low orders, and some cruise cars are also unaccompanied due to difficulty in achieving expected returns. It is recommended that companies intending to engage in online car-hailing operations carefully research the market, gain a deeper understanding of policies, and cautiously invest in Jinan’s online car-hailing market to avoid economic losses.

The robot sings the leading role, cool ＂black technology＂ appears at the Internet Light Expo.

　　You can also pay for brushing your eyes, unmanned vehicles run out of the street, and robots parking service.

New Internet technologies began to flock to Wuzhen.

　　Yesterday, the third world internet conference Internet Light Expo opened in Wuzhen. More than 310 Internet companies at home and abroad have brought a number of new Internet technologies and achievements that are the most advanced and cutting-edge in the world.

　　Ma Yun also arrived in Wuzhen yesterday evening. He "bought some cakes and then walked into a private restaurant". This time, he brought new technologies such as urban data brain, artificial intelligence ET, and face-scanning payment.

　　Baidu unmanned vehicles have also started to operate dynamically in Wuzhen in the past few days.

　　Hikvision’s intelligent parking robot, which is being put into trial operation in Wuzhen, also appeared at yesterday’s Internet Light Expo.

　　More and more Internet technologies are being fermented in Wuzhen.

　　Ma Yun brings new payment technology.

　　Previously, Alibaba had launched "brush face payment", but at this Internet conference, Alibaba brought "brush eye payment".

　　"Brush eye payment" is a "black technology" based on eye pattern recognition technology, which attracted the media’s enthusiasm and attention on the spot. As long as the user stares at the smartphone camera and turns his eyes to both sides, the software will be able to analyze the distribution map of eyeball blood vessels in the photos taken by the camera and establish unique ID data for the user.

　　"Eye white texture, like fingerprints, has become the password for payment. The software accuracy rate of this pure biotechnology can reach 99.99%, which is more economical and convenient than iris and fingerprint sensors." On-site related personnel introduced.

　　Tang Liang, the activity development and operation department of Alibaba Group, said that at this Internet conference, they also brought new technologies such as urban data brain, artificial intelligence ET and face-scanning payment technology.

　　Baidu unmanned vehicle is on the road.

　　Remember the driverless car that showed up at the world internet conference last year? Last year, with many doubts, this year has begun to "run."

　　Different from last year, Baidu unmanned vehicles will be operated on the real urban roads in Wuzhen. It is understood that before the opening of this Internet conference, Nokia Internet of Vehicles built a base station in the extension of midnight road in Wuzhen, and Baidu driverless car conducted a road test in the extension of midnight road.

　　This also means that the cooperation between the Internet town Wuzhen and Baidu to build the world’s first unmanned vehicle operation scenic spot has gradually matured.

　　According to reports, in the demonstration car on this "fully transparent" road, you can see that the mobile phone terminal or vehicle terminal perfectly realizes the map navigation application combined with real-time traffic video, and the full-motion video switches rapidly with the change of vehicle position. Travelers can not only get daily road information on navigation, but also click on the screen to directly check the real-time road conditions and make travel arrangements in advance in a more intuitive way.
