The brakes fail while driving. Can you turn off the car？

Careful drivers may find that when the vehicle is turned off, the brakes can’t be stepped on. Many drivers wonder why this is so. Some drivers may consider that if the car stalls during driving, will the brakes fail? How do I park my car?

After the flameout, why can’t the brakes be pressed?

After the car is turned off, some cars are hard to step on the brakes, and some cars are empty and unresponsive. This phenomenon has also been discovered by many drivers. The specific reason is simply that the car brakes need the engine to work to generate vacuum to provide brake power. After the engine is turned off, the vacuum required for brake power is gone, so the brakes can’t be stepped on.

Cann’t you step on the brakes when you’re driving?

According to the above theory, after the car is turned off, the brakes should really be stuck, but this is only limited to automatic cars. Because after the automatic car is turned off, the engine immediately stops rotating, even if it is hung in the D gear, the wheels can’t drive the engine to rotate, and without rotation, it can’t produce vacuum power.

However, the manual transmission car is different. After the engine is turned off, as long as it is not in neutral, the rotation of the wheels can still reverse the rotation of the engine. As long as the engine rotates, it can continue to generate vacuum and provide braking assistance. Therefore, when the manual transmission car is turned off during driving, don’t put it in neutral, keep the original gear and just step on the brake, which can also give the engine a reverse braking force and make it easier to stop.

What should I do if I turn off the engine while driving?

How to stop the car when the automatic brake fails? Remember these operations to save your life. No matter what car it is, the brake is always the most critical core, which is directly related to the safety of all of us. It is a creepy thing for every driver to hear that the brakes are out of order. When encountering such things, we must be calm and often panic, and blind operation will only brew a bigger accident. The essence of the difference between automatic transmission and manual transmission is that the gears of automatic transmission are divided into P, R, D, L, S and N. Although there are so many gears in automatic cars, most car owners like to use D gear when driving, because this gear is really convenient to operate. But what should you do once the brakes of an automatic car fail and the speed is at a high speed of 120 yards?

When the brakes fail, the first thing to do is to calm down, don’t be very impatient, and don’t touch the west. If you turn the steering wheel wrong, there will probably be an accident. The first thing you have to do is to turn on the double flash in the car. Only when the double flash is turned on, the people behind will know that there is something wrong with your car, and they will pay attention. When they approach you, they will slow down and bypass you. If your car is automatic, you can switch to manual mode, which is a car that can reduce the gear and brake automatically. You can also shift the second gear first, and then shift the L gear, but be careful not to shift the P gear or the R gear to avoid accidents. If these don’t work, you need to find some objects and make full use of friction to reduce the speed and achieve the braking effect.

Rational use of control vehicles. Automatic transmission When it is found that the brake of the vehicle is out of order, first release the accelerator pedal, and put the gear on the manual transmission to lower the gear from the high gear to the low gear in turn. Among them, the braking effect of automatic transmission vehicles is generally not as obvious as that of manual transmission vehicles, and some vehicles will prohibit automatic gearbox downshifting in order to protect the gearbox, so the gears should be lowered in turn after each downshift. Similarly, when pulling, the brake release button should be pressed and pulled continuously, and it cannot be pulled to death. The same is true for electronics. After pulling, press it until the vehicle stops and hangs in the parking gear. If the brakes suddenly fail when the car is driving at high speed, it can be braked directly by electronics. After starting the electronics, the braking system will brake the four wheels slightly lower than the full braking, and the full braking will only be carried out when the speed of the car slows down or is close to a stop. However, it is worth reminding that in the process of emergency braking, if the vehicle is turned off, the electronic function still works. It should be noted that the electronic switch must be held, and only in this way can the braking effect be achieved. It’s useless if you just pull it and let it go.

1. Don’t hesitate to step on the brakes immediately.

After the vehicle is turned off, the vacuum of brake booster will not be lost immediately, and the brake will not fail immediately, but there is no power booster system, and the brake pedal is hard to step on, which can not achieve normal braking effect. But our top priority is not to hesitate. We should put on the brakes at once and use a little more strength. Usually, we can stop the car.

When braking, don’t step on it twice, because stepping on the first foot will consume the vacuum, and the braking effect will be greatly weakened when stepping on the second foot, so you need to step on it once, and you can’t choose to use the point brake method.

2. Don’t hit the direction

The engine not only provides braking power, but also provides steering power for the steering wheel. When the engine is turned off, the steering pump that provides power for the steering wheel will also lose power. At this time, the force required to turn the steering wheel is very large, and it is hard for an adult to turn, making it even more difficult for girls to turn. So at this time, we should not beat the steering wheel, so as not to turn back, just grasp the direction and keep the vehicle straight.

control

After the brake fails, it can be used to brake, but it should be controlled properly, and the car should not be pulled suddenly because of panic, otherwise the steel wire rope will be broken because of excessive force, which will make the car fail, or the rear wheel of the car will be locked and the car will be out of control.

The correct way is: in high-speed driving, the first thing to do is to loosen the throttle and slow down by downshifting. When the speed is slightly stable and obviously drops, pull the car to stop slowly, and tighten, loosen, tighten and loosen it several times to slow down the car. It should be noted that when pulling the handle of the car, you should press the safety button of the handle, so that the handle can be operated freely in the process of tightening and loosening, and the car can be prevented from locking when tightening.

The electronics of some models also have the function of assisting emergency braking (this function needs to consult the manufacturer or dealer). If extreme conditions occur during driving, you can first release the throttle and operate the electronic button to brake the vehicle. This situation is somewhat complicated. By pulling up the button, the vehicle will brake urgently. Note: at this time, the braking of the vehicle is not mechanical parking. Under high speed, the emergency braking is to hydraulically brake all four wheels through the ESP control unit with a force slightly less than the full braking force, and when the vehicle is close to the static state, it can be slowed down or parked directly by electronics.

Forced downshift

In this way, manual transmission and automatic transmission are different. A car with manual transmission should first step on the clutch to the end, then retreat into neutral and then release the clutch. Then step on the accelerator as much as possible, and then step on the clutch to the end. At this time, retreat to the low gear, put the clutch in a semi-linkage posture and put it back. Automatic transmission vehicles can adjust the gear by shifting paddles and manual modes.

Emergency lane avoidance

If the above methods still can’t brake, you need to turn on the double flash at this time to avoid hurting innocent vehicles. At the same time, it is necessary to find some suitable sections to slow down. It is a good choice to have that kind of emergency escape or uphill road.

Why did it stall?

When the vehicle stops, it can’t be started by ignition, and it is ready to drive away. We must first check what causes the flameout. Usually, there are three reasons:

1. Device failure

Generally, the ignition coil, capacitor and electronic ignition module fail. Usually, there is no problem in the initial ignition, but it will turn off after a period of time, and then it will turn off after a period of time, so frequently.

2. Circuit failure

In case of flameout caused by low-voltage power failure during driving, the switch and fuse box of the starter should be checked at this time.

3. Oil circuit failure

There is no oil in the fuel tank, the gasoline pump is damaged, the oil pipe is broken, and the oil inlet is blocked, all of which may cause the car to stall during driving. The car stall caused by oil circuit failure is usually difficult to start again, but sometimes it can be re-ignited.

When the car turns off during driving, you should first be calm and don’t panic. If the brakes really can’t stop the car, you can choose to pass, but be careful not to pull the brake line too hard, so it will not pay off. There is another way to quickly put N gear, and then start the car by ignition during driving, but at this time, you must pay attention to the surrounding vehicles, and if necessary, you can turn on the double flash to remind the surrounding vehicles. When you start up, you still have to park the vehicle on the side of the road slowly, and then get off the bus to check the vehicle failure.

The back of the shopping receipt is stamped with the ＂exemption＂ seal, so can the supermarket really be exempted？

　　Is it stamped?

　　The relevant person in charge of the supermarket said that there are many professional counterfeiters recently, and their counterfeiting is not formal, but the goods are switched and stolen. In order to avoid the situation that the professional counterfeiters can’t define the goods by changing the package, so when paying the bill at the cashier, the receipt is stamped.

　　Any tips?

　　The reporter noticed that the cashier didn’t give any tips before stamping the receipt, and the stamp on the back of the receipt was "Xinhua Store confirmed that the goods had not passed the shelf life when shopping". The cashier stamped each customer’s shopping receipt, and the customers hardly noticed it.

　　Is there something fishy?

　　The lawyer said that the act of stamping the small ticket is that the supermarket pushes the responsibility to the consumer, which unduly increases the responsibility of the consumer. If consumers buy goods for a long time, it is difficult to prove, and the stamped receipt is more conducive to the supermarket to prove that they have not sold expired goods.

　　When buying goods in the supermarket, have you ever noticed the cashier’s receipt handed over by the cashier and the goods? On July 13th, Mr. Zhou, a citizen who often shops in Renrenle Supermarket (Xinhua Store) and has the habit of keeping shopping receipts, suddenly found that there was a little more on the receipts than before.

　　It turned out that after shopping in the supermarket, the cashier stamped a seal on Mr. Zhou’s cashier’s receipt, "It was confirmed that the goods had not passed the shelf life when shopping." Mr. Zhou believed that the supermarket did not make a public notice of this requirement beforehand, which was a voluntary exemption and actually harmed the legitimate rights and interests of consumers.

　　In this regard, the relevant person in charge of the supermarket explained that the move was mainly to prevent professional counterfeiters from bringing expired food that does not belong to the supermarket into the supermarket in the form of "package transfer".

　　Customer query

　　Stamping is a unilateral exemption for supermarkets.

　　On July 13th, after shopping in Renrenle Supermarket (Xinhua Store), Mr. Zhou, a citizen of Chengdu, accidentally found a red seal on the back of the shopping receipt with the words "It was confirmed that the goods had not passed the shelf life when shopping". Mr. Zhou told Chengdu Business Daily-Red Star News reporter that he is a frequent visitor to this Renren Le supermarket, and he usually has the habit of keeping shopping receipts. This time, he found "different" behind the receipts.

　　In order to verify whether the store acted unilaterally or other Renrenle supermarkets had this provision, on July 15th, Mr. Zhou bought goods at Renrenle Supermarket (Qianfeng Store). This time, the back of the shopping receipt was not stamped. On the same day, Mr. Zhou came to Renrenle Supermarket (Xinhua Store) again. This time, he noticed that when checking out at the cashier, the cashier stamped the back of the printed receipt.

　　In this regard, Mr. Zhou believes that the supermarket has not made relevant public announcements to inform consumers before, which belongs to the unilateral exemption of the supermarket, which actually damages the consumers’ right to know and the rights to legally defend their rights.

　　Journalist visit

　　There is no hint before stamping.

　　On July 16th, a reporter from Chengdu Business Daily-Red Star came to Renrenle Supermarket (Xinhua Store) and found a seal with a red background on each checkout counter. After other consumers settled the bill, the cashier stamped the receipt. No consumer objected to this behavior, and some even didn’t take the receipt away.

　　The reporter bought a drink as a consumer. When checking out, the reporter noticed that the cashier didn’t give any hint before stamping the receipt. The stamp on the back of the receipt was "Xinhua Store confirmed that the goods had not passed the shelf life when shopping". The reporter saw at the scene that the cashier had stamped each customer’s shopping receipt, and the customers were almost unaware of it.

　　Later, the reporter visited other stores of Renren Le Supermarket, but did not find the act of stamping the back of the shopping receipt.

　　Supermarket response

　　Prevent professional counterfeiters from cheating.

　　"Mainly to prevent professional counterfeiting, there is nothing for other (customers)." The relevant person in charge of the customer service department of Renrenle Supermarket (Xinhua Store) explained that because there are so many professional counterfeiters in the supermarket recently, their counterfeiting is not formal, but the goods are switched and stolen. In order to avoid the situation that the professional counterfeiters can’t define the goods because they switch packages, so when paying the bill at the checkout counter, they stamp the receipt and take it back after the goods are sold, saying that it has expired. The supermarket is not responsible. "We also have a reminder on the radio, which is broadcast once every half hour, so that everyone can pay attention to the shelf life and collect shopping receipts." The person in charge said that the supermarket has fulfilled its obligation to inform.

　　Subsequently, Mr. Tan, the person in charge of Renrenle Supermarket in Chengdu, contacted the reporter and explained that a warm reminder was posted in the eye-catching position of the supermarket: "This mall refuses to sell expired goods, please tell the employees of this mall if you find it", which is also to provide customers with quality goods. The act of stamping the official seal is to confirm with the customer (check the shelf life of the goods) and also to consider the safety and health of the customer. At the same time, it is also a kind of protection for both parties to confirm with consumers whether the goods have expired because of the behavior of professional counterfeiters "switching packages".

　　Mr. Tan also said that everyone in the city has this initiative, which started three months ago. However, the reporter suggested that the visit found that only Xinhua Store used the stamp method, and the other party asked which supermarkets needed to assess the service quality.

　　Lawyer’s statement

　　Stamping is an act of shirking responsibility.

　　Liu Xiu, a lawyer of Taihetai Law Firm, believes that supermarkets have a substantive obligation to review whether the goods they sell have passed the shelf life, and consumers have no obligation to review and confirm. (The act of stamping the receipt) is that the supermarket pushes the responsibility to consumers, which unduly increases the responsibility of consumers. Consumers usually don’t pay attention to the tips on the product receipt. If consumers find that the product has expired after returning home, even if they stamp it, they can’t be exempted from the responsibility of the supermarket.

　　Xing Lianchao, a lawyer of Sichuan and Law Firm, believes that supermarkets should stamp the cashier’s receipt with the seal of "Confirmed that the shelf life has not expired", so both parties should confirm the goods sold on the spot before checkout to avoid disputes in the future. If there is no confirmation behavior, it will be wrong for the operator to stamp it directly.

　　Generally speaking, by comparing the shopping receipt and date of purchase with the shelf life of the goods, we can find out whether the goods have expired after purchase. If it is said that consumers spend too long buying goods, it is difficult to prove, and a small receipt with a seal is more conducive to the supermarket to prove that they have not sold expired goods, and consumers need to prove.

Technical blockade! Automatic gearbox inventory of dozens of autonomous vehicles

　　　 [XCAR Information Original]　

　　　　As we all know, engine, gearbox and chassis are the three key components of an automobile, and they are also the core technologies that a vehicle manufacturer must master. In the last article, we talked about the achievements of independent brands in engine research and development. In the early stage, independent manufacturers mostly used imitation and purchase to obtain engine technology. Compared with engines, the lack of self-owned brands in automatic gearbox technology is more obvious. The research and development of automatic gearbox is difficult, with high technical content, and it is difficult to imitate in a short period of time, which makes it impossible for self-owned brands to develop automatic gearboxes that can be applied on a large scale at present.

Technical blockade! Automatic gearbox inventory of dozens of autonomous vehicles

　　　　There is a great demand for automatic gearbox in the market, and the demand is still growing, which makes independent brands can only obtain automatic gearbox by purchasing. However, the lack of their own technology and the restrictions of foreign gearbox manufacturers also lead to the limited choice of automatic gearbox for independent brands, and most of the products they carry do not have much technical advantage. Today, what we are going to introduce to you are several automatic gearboxes that are common in our own brand models.

　　　● AT gearbox

　　　　Manual gearbox is mainly composed of gears and shafts, which produce variable speed and torque through different gear combinations; The automatic gearbox AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which realizes variable speed and torque by means of hydraulic transmission and gear combination.

　　　　Hydraulic torque converter is the most characteristic component of AT gearbox, which is composed of pump wheel, turbine and guide wheel, and directly inputs engine power to transmit torque and clutch action. Pump wheel and turbine are a pair of working combinations, which are like two fans placed opposite each other. The wind from one active fan will drive the blades of the other passive fan to rotate, and the flowing air — — Wind becomes the medium of kinetic energy transfer.

AMT gearbox　
Hydraulic torque converter of conventional automatic gearbox

　　　　If air is replaced by liquid as the medium to transfer kinetic energy, the pump wheel will drive the turbine to rotate through the liquid, and then a guide wheel is added between the pump wheel and the turbine to improve the transfer efficiency of the liquid. Because the range of automatic speed change and torque change of hydraulic torque converter is not large enough and the efficiency is low, several rows of planetary gears are connected in series behind the turbine to improve the efficiency, and the hydraulic control system will automatically control the planetary gears with the change of engine work, thus realizing automatic gear shift.

　　　　Self-owned brand AT gearbox provider 1: Aisin Seiki

　　　　Manufacturer profile:Japan Aisin Seiki Co., Ltd. is one of the world’s top 500 enterprises and the ninth largest auto parts manufacturer in the world. Founded in 1949, the company is the main supplier of Toyota auto parts, and its auto parts manufacturing technology is world-famous.

　gearbox
Aisin Seiki provides AT gearboxes for most domestic independent manufacturers.

　　　　Aisin Japan Co., Ltd. is an import and export trading company specializing in auto parts, auto warranty equipment, hardware, mechanical equipment, power tools and other products. About 95% of the company’s sales come from auto parts, but the company also manufactures refrigeration equipment and cutting machines, as well as consumer products such as beds and sewing machines. Aisin Seiki has subsidiaries in the United States, Europe, Asia and Australia.

　　　　Roewe 750

　　　●　continuously variable transmission

　　　　CVT has no specific gear, and its operation is similar to that of automatic gearbox, but the change of speed ratio is different from the trip stop process of automatic gearbox, but continuous, so the power transmission is continuous and smooth.

　　　　The advantages of CVT are as follows: First, the power output of CVT gearbox is linear, and the shifting frustration caused by it also disappears, which is very smooth in actual driving. Secondly, the transmission system of CVT can have infinitely many gears in theory, and the gear ratio, speed ratio and the balance of performance, fuel consumption and exhaust emission in the traditional transmission system are easier to achieve. Finally, the mechanical efficiency and fuel economy of CVT transmission are much better than ordinary automatic transmission, second only to manual transmission, and the fuel economy is much better.

gearbox
continuously variable transmission

　　　　So CVT has no shortcomings? The answer is no, first of all, when starting or accelerating, CVT steel belt or belt is prone to slip, which will affect the power transmission, thus affecting the acceleration feeling. Secondly, CVT steel belt or belt material requirements are relatively high. Although CVT has a simple structure, if it fails, it is generally not a minor problem. This will affect the use of car owners and increase maintenance costs.

　　　　●AMT gearbox

　　　　Automatic mechanical transmission (AMT) is a new type of transmission that electronically controls the traditional dry clutch and manual gear transmission to realize automatic shifting, and its control process basically simulates the driver’s operation. According to the driver’s intention, the electronic control part of AMT gearbox can automatically control the clutch and shift process. More complicated, we don’t need to go into details. In fact, we can imagine the shift process of AMT in this way. His clutch and shift mechanism are controlled by electronic parts, and the shift will be automatic naturally.

AMT gearbox　
Electric control device and hydraulic actuator of AMT

　　　　The biggest advantage of AMT gearbox is that it does not need to make too much changes to the existing manual gearbox, and its technical structure is relatively simple, and the cost is not too high for manufacturers. In fact, AMT is a manual gearbox with electronically controlled clutch and shift program, so it is the same dry clutch as manual transmission, so the transmission force is more direct and the fuel consumption is more economical. The ordinary AT gearbox adopts hydraulic "clutch", which will have some losses in energy transmission and slightly higher fuel consumption.

AMT gearbox
AMT is somewhat similar to an automatic manual transmission.

　　　　Of course, AMT has obvious shortcomings, that is, the shift quality is not high and it is prone to frustration. If you don’t step on the accelerator, the car won’t move forward even if you shift into D gear. This is somewhat different from the ordinary AT gearbox.

Take stock of the entrepreneurial experience of Liu Qiangdong, Lei Jun and other eight Internet tycoons with money.

On the road to starting a business, who hasn’t stumbled?

However, they didn’t collapse because of a fall, but learned a lot of entrepreneurial experiences and lessons from their failures and cheered up again.

Today, let’s take a look at 10 Internet tycoons’ entrepreneurial experiences!

— — Lazy cat president

　　　　　　　　

This paper takes stock of the entrepreneurial projects that 10 Internet tycoons have failed, and the wealth of experience they have learned from them.

It is these experiences that have made these internet giants achieve today’s achievements, and these experiences are more precious for entrepreneurs now.

Before his success, he founded tricolor company and went bankrupt because he could not make a profit.

Lei Jun — — Founder of Xiaomi, now valued at $45 billion.

When he was in college, Lei Jun read a book about Gates and Jobs’ early entrepreneurial legends, The Fire of Silicon Valley, which greatly touched him — — "I was deeply attracted by the story of Jobs.

After working hard in Wuhan Electronic Street for a period of time, I felt good about myself and began to dream: I dreamed of writing a set of software to run on every computer in the world, and I dreamed of setting up the best software company in the world. "

So, he founded Tricolor Company with three friends in his senior year. Unfortunately, the company was forced to dissolve in half a year.

In this regard, Lei Jun has three reflections:

First, there must be a clear profit model.

In the company’s business, the three-color company has no fixed model. When it sees anything to make money, it makes a sum. "At most, there are fourteen people, and the business scope is quite wide. They have sold computers, made imitation Hanka (a kind of computer hardware), and even took over the work of typing and printing."

Therefore, their funds have been very tight. When I really have no money, I even earn a living by playing mahjong with the canteen chef to win food tickets.

Second, we must have a forward-looking market awareness.

In fact, they were close to success. At that time, Lenovo Hanka created a brilliant profit of hundreds of millions, so Lei Jun and his partners decided to copy this product.

However, after the product went on the market, they met a more powerful shanzhai king and made their products "shanzhai" again. Moreover, the company was large in scale and low in price, which finally crushed the three-color company.

Third, we must have certain team management skills.

When the company was founded, "four people, each with a 25% stake, were all very happy. A few days later, the problem came, and everything needed to be discussed repeatedly. Later, the general manager was even re-elected twice. "

And such a management structure, it is impossible to form an effective decision.

When studying at Nanyang Technological University, Chen Ou built an online game platform GG with a computer.

As a professional player, Chen Ou invited two top Warcraft masters who have never played against each other: WCG champion Moon and ESWC champion to have a peak matchup, and the platform for the matchup is GG. This won him the first batch of users.

However, with the increase of the number of users, Chen Ou, which has no capital reserves, is increasingly embarrassed, and the sponsors it can get are a drop in the bucket, and investors are dismissive of this fledgling entrepreneur. This makes the development of GG difficult.

At this time, Chen Ou wanted to go to Stanford to study for an MBA, so he introduced a professional manager to take care of the company and sold part of his equity.

Subsequently, the professional manager introduced other angel investors, and through the operation, Chen Ou’s equity was only over 30%, and he lost control of the company and was finally squeezed out of the company.

In his second venture, Chen Ou set up a game company in China, and its business model imitated that of the United States, with advertisements built into social games. However, due to the great difference between the domestic market and the United States, the company soon declared bankruptcy.

These two entrepreneurial failures have given Chen Ou two gains:

First, the company needs to have a good equity organization structure.

Second, simply copying foreign models will not work.

Zhen Ronghui, the founder of Worry-Free Future, has a market value of $2 billion. Invested in voice mail and magnetic materials.

Zhen Ronghui — — As a consultant before starting a business, I am a professional manager with an annual salary of one million.

In the tide of rapid economic development in mainland China, he conceived the ideal of "billionaire", so he worked part-time as a voice mail delivery system and invested in magnetic materials. But both ventures ended in failure.

These two experiences made him learn a lot. In conclusion, he said:

First, starting a business requires a lot of energy, and you must do it full-time; At the same time, the team is also very important.

Second, starting a business can’t just start from products. Good products don’t mean having customers, and customers need complete services. Therefore, entrepreneurship needs to change from product orientation to customer orientation.

Wang Xing — — Founder of Meituan. com, with a valuation of $7 billion. He founded the intranet and was forced to sell it.

In the winter of 2003, Wang Xing, a doctoral student in the United States, took a long vacation from his tutor and returned to China to start a business.

After several failed projects, Wang Xing found that the acquaintance socialization among students was a cut-in point, so he set out to build the campus network.

On the website interface, they copied Facebook, which was criticized by everyone. However, because Facebook’s design is very user-friendly, the user experience of the intranet is the best compared with the competitors who independently design the interface. This has retained many users for them.

At that time, the subway in Beijing was inconvenient, and it was very troublesome to go to the railway station by car.

Therefore, during the winter vacation, Wang Xing launched a registered campus network in Tsinghua, Peking University and the National People’s Congress, and took the bus to the railway station for free. At the same time and at the same place, 50 people will start.

In order to make up the number of people, students spread the word everywhere and registered fellow villagers. Some boys even took the bus to the railway station instead of taking the train to get to know a girl.

With this move, the campus network got 8000 seed users, and everyone began to be active on this website.

However, due to his first venture, Wang Xing did not have his own theory, his understanding of the Internet was not deep and he lacked a clear profit model. The capital side was not optimistic about the project of the campus network.

Finally, the capital chain broke and the internal team had a dispute, so Wang Xing was forced to sell it.

The failure of this project inspired Wang Xing as follows:

First, the entrepreneurial team must have a clear division of labor, and the CEO must be liberated to pay attention to the trend of the whole industry, times and social development.

Second, rapid promotion is very important.

Third, we don’t need blind self-innovation, and learn the advantages of others quickly.

Fourth, we should contact capital as soon as possible, lower our posture and make some compromises.

Fifth, we must start a business with people we trust. Only trust can keep the team stable in the case of low tide.

Wu Xinhong — — Founder of Meitu Xiu Xiu, with a valuation of $3 billion. He founded the 520 social platform and then stopped operating.

In 1999, Wu Xinhong, a senior high school student, saw a piece of news: a domain name called "business.com" sold for $7.5 million in the United States.

So I borrowed 10,000 yuan from my family and started to invest in domain names. With this investment, he made some money and got to know Cai Wensheng, a later investor.

In 2002, Wu Xinhong, who had dropped out of school at home, found a good domain name: 520.com, so he prepared to copy Tencent and collect money through membership fees, that is, only when you are a paying member can you get the online contact information of the other party.

After doing it for two years, 520 has accumulated hundreds of thousands of paying members, but because the products and operations can’t keep up, most members stop using it after only paying for one month.

Therefore, Wu Xinhong was forced to shut down 520 and sell the domain name.

Looking back on this experience, Wu Xinhong said that there are two lessons:

First, reverse entrepreneurship, that is, setting up a company through a good domain name, is completely unreliable.

Second, more importantly, I was very homely, and I was not sociable at that time. I didn’t know what the real needs of users were, let alone being a dating site.

Liu Qiangdong — — Founder of JD.COM, with a market value of $40.3 billion. He once opened a restaurant in Zhongguancun, but closed after being cheated of money.

After graduating from Liu Qiangdong University, I set aside a restaurant near Zhongguancun.

In the past, the clerk in the restaurant had a low salary, lived in the basement, and usually only ate leftovers. The boss personally controlled the funds.

After Liu Qiangdong took over, he raised his salary, improved the accommodation environment, served the shop assistants with delicious food and hot drinks, and let them do the purchasing and cashier.

This young man who started a business with idealism confused trust with management and suffered the first setback in his career.

Due to the loose management, employees always find ways to embezzle the money in the store, so it took no year, and the originally profitable hotel lost all his investment.

The lesson Liu Qiangdong got from this is that we must trust employees, but trust does not mean that there is no management.

At that time, Chen Yizhou, who was still studying at Stanford, and others designed a combination named ChinaRen according to the characteristics of several popular community websites in the United States at that time, which means combining Chinese and western.

But no one in Silicon Valley wants to invest in their projects. In the end, I only raised $200,000 from my classmates at Stanford.

In March, 1999, they went back to China to register their company. After receiving the investment from Goldman Sachs, they quickly launched the ChinaRen community and obtained tens of millions of dollars in new financing. After financing, ChinaRen began to burn money and smash advertisements crazily.

Chen Yizhou — — Founder of Thousand Oaks Interactive, with a market value of $1.1 billion. He founded ChinaRen community and later renamed it renren.

At first, Chen Yizhou and others were afraid, but investors said that it didn’t matter. After burning, there would be investment, and there would be no way to go public without burning. But soon, the American stock market crash came in 2000, and capital entered the cold winter.

Therefore, the attitude of investors who supported burning money changed greatly, and they told Chen Yizhou clearly that there would be no new investment, so they sold the company as soon as possible. So Chen Yizhou had to sell ChinaRen community to Sohu.

In fact, this case is similar to the intranet:

To start a business, we need to make rational use of the existing capital, and it is best to have our own hematopoietic capacity, so as to survive the crisis safely in the cold winter of capital.

Zhou Hongyi — — Founder of 360, with a market value of $64. Once built 3721, one of the earliest search engines in China.

Before doing 360, Zhou Hongyi once worked as a search engine called 3721, and Baidu also launched a similar service.

The two sides competed fiercely for each other’s territory, so Zhou Hongyi added a module to the client of 3721, which was specially used to delete Baidu’s client.

This module cannot be deleted, which also left Zhou Hongyi with the title of "Father of Rogue Software".

The beginning of this mistake was followed by a wrong decision.

Zhou Hongyi said that at that time, he felt that Baidu had a better search mode than himself, and the Internet in China was also very depressed at that time.

Therefore, in the case of high market share, he chose to sell 3721 to Yahoo, which led to the search of this $1 billion market and was finally occupied by Baidu.

Regarding these past years’ experiences, Zhou Hongyi said: We should not only focus on our opponents, but also focus on users’ needs, and we must stick to our own career and don’t give up easily.

On the road to starting a business, who hasn’t stumbled?

Even Lei Jun, Zhou Hongyi and Liu Qiangdong … … These internet giants have also experienced the lessons of blood, but they have not been devastated by a fall, but have learned a lot of entrepreneurial experiences and lessons from their failures and revived.

There was no successful model at the beginning, so they experienced many failures and finally succeeded with wisdom and will.

Nowadays, starting a business is no longer difficult, and there are many successful experiences to learn from.

In the era of real estate speculation, many people seized the opportunity, so they struggled less for decades.

Nowadays, in the Internet era, it is very important to assess the situation and seize the trend! Pigs on the tuyere can also fly!

Standing in the right place is like stepping on a giant’s shoulder, then success is within reach!

During the period of Spring Festival travel rush, it is estimated that the passenger volume of Chongqing Tiegong will reach 32.014 million, up by 7.1% compared with 2024. On the same day, reporters came to bus stations, railway stations, airports and other places and found that the major transportation hubs in our city have introduced various safeguard measures for Spring Festival travel rush to ensure the safe travel of the vast number of passengers.

Multiple measures to ensure the smooth operation of Spring Festival travel rush

It is understood that the biggest feature of Spring Festival travel rush this year is that the Spring Festival holiday has been increased to 8 days, with more passenger flow, and comprehensive transportation is facing greater challenges. It is estimated that during the period of Spring Festival travel rush in 2025, the passenger flow of railways, rail transit and civil aviation in our city will increase by 15%, 4.8% and 3% respectively. Stimulated by the free passage policy of expressways, the traffic volume of expressways in our city will also increase significantly.

To this end, the city will optimize the train frequency and running time in a timely manner, and adopt ways such as opening special trains and opening more passengers to ensure the smooth and orderly transshipment of important nodes such as Chongqing West Railway Station and Chongqing North Railway Station; Strengthen the connection between roads and airports, railway stations, tourist attractions, large communities, etc., and improve the coverage of road passenger customized services; We will increase the security of rural transportation services, and effectively protect the travel needs of urban and rural people by opening shuttle buses (buses) and carrying out appointment response services.

In order to ensure Spring Festival travel rush’s travel, our city will increase the capacity guarantee. The relevant person in charge of the Municipal Transportation Commission said that during the Spring Festival travel rush period, the city is expected to invest 854 pairs of railway passenger trains, 18,000 passenger vehicles, 341 water transport capacity and 40,000 civil aviation transport capacity; There are about 6,500 buses, about 330 rail trains, 15,000 cruise taxis and 52,000 online taxis in the downtown area every day.

At the same time, in view of the routes around the core business districts and popular scenic spots, the city will extend the bus operation hours in a timely manner and actively explore emerging market businesses such as tourist chartered cars to adapt to the night travel habits of citizens and tourists coming to Chongqing. Rail transit lines 1, 2, 3, 4, 6 and 10, loop lines and other lines will flexibly extend the operation time by increasing the number of empty cars, and increase the number of small roads and spare cars to ensure sufficient transportation capacity in the core area. Other rail transit lines and suburban railway jumpers and copper wires are flexibly arranged according to the characteristics of passenger flow along the line.

Ten sets of CR400AF-S Fuxing intelligent EMUs have been put in place.

The reporter learned from the railway department that 10 sets of CR400AF-S Fuxing intelligent EMUs have been put in place for the first time in Chongqing, and all of them will be put into Spring Festival travel rush this year. The maximum operating speed of the EMU is 350 kilometers per hour, which has the advantages of light weight, noise reduction, equipment integration and layout optimization. The number of train personnel increased from 577 to 619, and the capacity of large luggage rack doubled. Each carriage is equipped with a large luggage rack, which improves the passenger capacity of EMU trains and the stability of large luggage placement.

Chongqing Railway Station is also fully prepared for Spring Festival travel rush. On January 13th, the reporter saw at Chongqing North Railway Station that the passenger flow of middle school students who came to take the bus increased significantly. "This year, Spring Festival travel rush and Chongqing Railway Station are expected to send 9.4 million passengers, and the peak passenger flow will appear around the seventh day of the first month." Chen Yue, deputy director of Chongqing Station Workshop of China Railway Chengdu Bureau Group Co., Ltd., said that the passenger flow of students, visiting relatives and returning migrant workers will be scattered before the holiday, and the passenger flow will be relatively flat after the holiday. It is expected that the return flow of visiting relatives, the flow of working in the south, the flow of students and the flow of working in the north will be staggered in turn.

In Spring Festival travel rush this year, the station has set up green channels for verification and security inspection at each entrance, and emergency passengers who arrive 15 minutes before driving will be given priority security inspection by volunteers.

In addition, the station organizes party member, youth commandos and volunteers to provide service guidance in key parts such as the waiting room, ticket office and service desk to ensure the safety of passengers’ travel and the waiting order. At the same time, give full play to the brand role of "Malian Service Desk" and "Hongyan Service Station", a national demonstration site for learning from Lei Feng, and actively carry out "silver hair service" to provide caring services for elderly tourists.

Add ticket window and green channel at bus station.

On January 13, the reporter went to the four-kilometer bus station in Nan ‘an District, and the number of passengers increased somewhat compared with the past. "Soldiers, firefighters, survivors of heroes and heroes have special ticket sales windows, and we strictly implement the preferential treatment policy for transportation." You Wu, deputy manager of the passenger transport department of the four-kilometer bus station, said that it is expected that the average daily passenger traffic in Spring Festival travel rush this year will be the same as last year, with an average of 8,000 passengers per day and about 400 classes; The concentrated travel time of passenger flow is from January 25 to January 28, and the daily peak passenger flow is expected to be around 30,000. To this end, the station has successively opened manual ticket sales windows, expanded online and self-service ticket sales channels, and provided convenient ticket purchase services for passengers.

"During the peak passenger flow period, we will also temporarily adjust the departure area of some line buses to realize the orderly diversion of passengers and ease the operating pressure of the ticket office, waiting room and parking space." You Wu said that the station will dynamically allocate capacity through reasonable arrangement of flights to ensure that passengers queue less, get tickets, take cars and get home.

The airport sets up a special check-in counter for urgent and special passengers.

On January 13th, the reporter saw in T3A Terminal of Chongqing Jiangbei International Airport that three staff members wearing beige coats and ribbons were helping the check-in passengers. Their ribbons are printed with the words "urgent passengers, let me help you". "During this year’s Spring Festival travel rush, we will increase the number of standby personnel according to the number of passengers on the flight and increase the on-site support force." According to the relevant person in charge, Chongqing Jiangbei International Airport has introduced a series of Spring Festival travel rush safeguard measures.

For example, for specific groups of passengers such as express passengers, first-time passengers, and groups, exclusive check-in counters and eye-catching summoning tips are set up, and special personnel are also set up on both sides of the check-in island to form a linkage with all security links in the service chain to escort them. At the same time, the "three exemptions" transit service is also introduced, that is, no baggage collection, no exit from the quarantine area and no second security check.

In addition, Chongqing Jiangbei International Airport will arrange Spring Festival travel rush volunteers during peak hours to provide guidance, assistance and other services for passengers, and provide efficient and warm-hearted quality services. Provide the whole process of "love" guidance service for first-time passengers, elderly passengers over 60 years old, passengers carrying infants under 3 years old, disabled passengers and late arrival passengers.
