It is difficult to charge and store. How does the owner of electric bicycle insist on "pushing the cart into the house"?

Residential buildings are high-risk places for electric bicycle fires. According to the "Regulations on Fire Safety Management of High-rise Civil Buildings" issued and implemented by the Emergency Management Department in 2021, parking or charging of electric bicycles is prohibited in public halls, evacuation walkways, stairwells, safety exits and other places of high-rise buildings. Then why do car owners insist on "pushing cars into the house"? Why do you need to charge at home?

Not long ago, reporters also visited all parts of the country and found that it is still common for residents to bring electric bicycles or batteries into indoor charging illegally. The reporter learned that the lack of public charging facilities is the main pain point encountered by residents when using cars.

Insufficient public charging facilities are the main pain points.

In an old residential area in Tianjin, the reporter saw that it is more common for residents to put electric bicycles in the corridor at will or push them into the elevator. Although some residents parked their cars outside the building, they still took the batteries home to charge them for convenience.

In a community in Fengtai District, Beijing, the reporter saw that although public charging facilities for convenience have been set up next to residential buildings, and electric bicycles are reminded with eye-catching slogans that "do not enter the building and do not enter the house", some residents still turn a blind eye to this.

In a community in Dongsha Street, Liwan District, Guangzhou, some residents still push their electric bicycles into their homes to charge, knowing the risks.

In the street park of the nearby community, although a public charging area with more than ten charging ports is also provided, when the reporter visited, he did not see an electric bicycle charging here. In addition to spending more money, residents say that they sometimes want to use it, and they can’t find a vacancy. Even some non-rechargeable vehicles often stop in the shed to occupy a position.

Problems such as potential safety hazards reflected by residents and insufficient public charging facilities. The staff of the local community neighborhood Committee said that they would try their best to persuade illegal charging behavior during daily inspections. As for the expansion of public charging facilities, in addition to security factors such as anti-theft and fire prevention, it is also faced with problems such as limited space in old communities and the inability to distance itself from residential buildings. At present, it is difficult to advance.

Car owners do not pay attention to the safety of electric bicycles.

The reporter learned that in addition to the many car pain points mentioned in the above film, there is another aspect, that is, many car owners lack sufficient attention to the safety of electric bicycle batteries and insufficient understanding of battery quality. According to the statistical analysis of the National Fire and Rescue Bureau, the main causes of electric bicycle fire include battery overcharge, battery monomer failure, short circuit of electrical circuit and so on. It can be seen that battery quality is particularly critical. In particular, old batteries and modified batteries that have been used for a long time have no small safety hazards. Therefore, battery inspectors have also done relevant tests.

In order to test the difference of charging safety factor between an old battery and a new battery, inspectors first disassembled a common lithium battery for electric vehicles, and it can be seen that the battery is actually composed of 10 battery cells. Subsequently, the inspectors put two new batteries that have been disassembled separately and the old batteries that have been used for a long time into the experimental box at the same time, and carried out charging tests at a fixed temperature and under the same conditions.

Li Zhaoyang, Senior Engineer of Battery TestingThis orange curve is the temperature change of aging battery, and the blue curve is the temperature change of new battery. It can be seen that the temperature of aging battery rises faster than that of fresh battery when charging, which is 1℃~2℃ higher on average.

The inspectors also simulated the collision that may be encountered in the daily use of the battery and conducted a pressure test. It can be seen that the squeezed battery first appears obvious internal cracking sound, and then suddenly bursts. Then there was smoke coming out of the battery, and then it exploded and caught fire.

Huang Huanjie, Executive President of Guangzhou Electric Bicycle Industry AssociationWe also participated in the investigation of some fire cases, and found that the main problems were some small brand batteries, or some batteries with "three noes" products, which were refurbished and reassembled from old batteries.

Industry insiders remind that battery overcharge may lead to battery performance degradation, shorten battery life and even damage the battery, leaving hidden dangers. In addition to developing good habits, car owners must choose regular manufacturers when buying batteries for electric bicycles. Even if it is a new battery, it should be inspected or replaced within six months to two years.

Fire caused by electric bicycle entering the house.

In the face of the fire caused by electric bicycles, many netizens left messages on the Internet expressing concern. Poke the video and see what the netizens say.

All localities actively explore the experience and practice of combining "dredging" and "blocking"

According to the data of China Bicycle Association, by the end of 2022, the number of two-wheeled electric bicycles in China has reached 350 million, which is equivalent to one electric bicycle for every four people. With the popularity of electric bicycles and frequent accidents, it also puts forward new challenges and requirements for the original order and management of the city.

Experts said that in addition to improving the regulations and standards for electric bicycle parking and charging in relevant places from the legislative level, the relevant departments should actively explore the experience and practice of combining "sparse" and "blocking".

In Suzhou, the local government, functional departments and social subjects’ legal responsibilities have been defined for the production, sales, parking, charging and management of electric bicycles. At the same time, the civil air defense measures should be improved in conditional communities, with 24-hour remote video monitoring devices and independent smoke fire detectors.

Shen Qiuning, a community workerWe have also purchased "three defenses" insurance for residents. The so-called three defenses are fire prevention, theft prevention and loss prevention. If our vehicle is stolen in the process of using the charging facilities, or there are losses for other reasons, we can give a subsidy of up to 2000 yuan per vehicle when taking insurance.

In Fengtai District, Beijing, the local fire department is actively promoting the streets and property units under its jurisdiction to install intelligent ladder control systems in this community. With the help of the intelligent camera installed in the elevator box, the system accurately controls the electric bicycle and battery to "go upstairs by ladder" by means of "algorithm identification+sound and light alarm".

In terms of promoting the construction of electric bicycle charging facilities, Beijing also plans to build another 200,000 public charging interfaces in 2024 on the basis of the 950,000 public charging interfaces already built, so as to solve the charging pain of car owners.

Jilin Changchun police exposed the sweet online dating scam and destroyed an electric fraud gang for 7 days.

  Recently, after careful investigation, the West Square Police Station of Kuancheng Branch of Changchun Public Security Bureau of Jilin Province successfully destroyed a telecommunication network fraud criminal gang in just seven days, arrested seven suspects and solved more than 80 series of cases, involving more than 400,000 yuan.

  It is reported that on October 22nd, the police of the West Square police station combed and screened through the public security online platform to get clues. A woman surnamed Sun in Huai ‘an City, Jiangsu Province reported to the local public security organ that she had made a friend who claimed to be engaged in engineering in Wuxi through a well-known dating platform. After a week of chatting, the relationship between them became more and more intimate. Chen Mou also took the initiative to confess to Sun, claiming that he had bought a diamond ring as a gift and was going to meet Sun in Huai ‘an. However, Chen Mou claimed that he usually likes to drink red wine, but the plane was not allowed to carry it, so he sent a shopping link to Sun, asking him to "prepare" a few bottles of red wine to drink together. When he thought of the "big style" and the diamond ring gift that Chen Mou revealed in his usual chat, Sun was carried away by the sudden "love" and opened the shopping link without thinking, which cost 24,000 yuan. What she never expected was that after the arrival of five cases of red wine, Chen Mou had blacked out its WeChat and couldn’t contact it any more.

  After preliminary investigation, Huai ‘an police determined that this was a typical case of telecommunication network fraud in the name of dating, so they entered the relevant information into the national anti-fraud platform after filing the case.

  After screening, the police of West Square Police Station found that the delivery place of red wine in this case was Erdao District, Changchun City. Zhang Wei, the director, immediately assigned Yang Guang, the deputy director, to lead the police chiefs Zhao Dongsheng and Yang Dapeng to set up a task force to fully investigate this key clue.

  Through inquiry, the task force locked the delivery express station of red wine in a very hidden old residential area in Erdao District. In order to get more clues, the police secretly guarded around the express station for three consecutive days, and sure enough, they found a pair of suspicious men and women who drove a black car to the express station on time every afternoon and sent boxes of red wine to all parts of the country. The task force then brought the two into the key screening line of sight. After further investigation and intelligence research, the task force mastered the information of two suspects and several gang members, and successfully locked the suspects in two hiding dens, one of which was the "office place" dedicated to telecom fraud and the other was the "warehouse" dedicated to living and storing red wine.

  After investigation, the task force determined the organization structure, division of labor, modus operandi and activity rules of the gang, and made a careful arrest plan, only when the time is ripe.

  On October 29, in order to wipe out the gang, the task force and the police were divided into two ways, and went to the two suspect hiding dens in Kuancheng District and Erdao District to wait for the net.

  Yang Guang, deputy director of a route, led a team and secretly rushed to a residential area in Kuancheng District. Due to the early investigation, it was found that there was a monitoring probe outside the den and the people in the house were extremely vigilant, it was difficult for strangers to call the door open. In order to avoid scaring the snake, the police put on two sets of uniforms for the staff of the heating company and called the door open in the name of checking the heating pipeline. The police seized the opportunity and rushed into the room. They successfully arrested five suspects, three men and two women, who were chatting with the victim in front of the computer, and seized five computer mainframes used in the crime on the spot.

  Zhao Dongsheng, another route police chief, led a team and found Cao and Qiu under a residential building in Erdao District. They made a decisive attack and successfully arrested two suspects, and found 30 boxes of red wine in their residence that had not yet been delivered.

  So far, all seven suspects of the telecommunication network fraud criminal gang have been arrested. It was found through trial that since June this year, Cao and Qiu have gathered Qiao Mogang, Liu, Bao, Gao Mouxun, Li Mouxiao and others to form a criminal gang, purchased tools for committing crimes, defined the division of tasks, and Cao and Qiu trained gang members in "speech skills", mainly using a number of well-known dating platforms, pretending to be rich or successful men, and targeting single and divorced middle-aged women.

  After trying every means to win the trust of the murdered woman, the suspect lied that he had bought a gift and was going to meet the other party by plane, but the plane was not allowed to carry liquid. So he proposed that the woman could help him buy red wine and send a shopping link displayed as "French Ramon Satellites Dry Red Wine", which was made by the gang in advance. They labeled the low-priced red wine bought in 20 yuan and disguised it as high-grade French red wine ranging from 498 yuan to 998 yuan per bottle. As long as the victim clicks on the link and successfully pays, the money will immediately enter Qiu’s personal account, and immediately after the success, the victim will be blacked out, and the principal couple and gang members will collect the money in the bag.

  At present, the task force has preliminarily verified that the gang used the same means to defraud more than 80 women victims, involving 12 provinces and 38 cities across the country, involving more than 400,000 yuan. Now Cao and gang members Qiao Mogang, Liu, Bao, Gao Mouxun and Li Mouxiao have been criminally detained according to law, and another principal, Qiu, has been released on bail pending trial due to pregnancy.

  The case is being further processed. (Reporter Liu Zhongquan)

Heterogeneous in the transmission! Analysis of Toyota E-CVT transmission

  [Pacific Auto Network Technology Channel]What is it? Can realize the automobileSpeed change, torque change, direction change and on-off powerThe device is the transmission. The first car in the world was born in 1886, and the first transmission appeared soon after. It can be said that the development of transmission and automobile are synchronous. At first glance, E-, maybe everyone will naturally think of CVT, that is, CVT. Functionally speaking, E-CVT does have the function of stepless speed change, but structurally speaking, the difference between them is too great. It can even be said that there are two types of transmissions, one is E-CVT and the other is other transmissions.

● Introduction of E-CVT

  At the beginning, we mentioned that E-CVT is not a simple "electronically controlled continuously variable transmission", so of course it is not circulated on the Internet. It is an electronic version of CVT. Toyota’s official definition is "power distributor", because it does not have complex mechanisms such as traditional gearbox system or gear shaft set, and it is a power distribution mechanism specially prepared for hybrid vehicles. Therefore, there has always been a debate: is E-CVT a transmission?

 

For more articles about gearbox classification, please click the following figure to browse:

Inner chain 1

 

  Whether it is a transmission or not, we will discuss it later. What we can see is that the THS( Hybrid System) is becoming more and more mature from 200h to the later hybrid version. As a key component of the whole system, E-CVT undoubtedly plays a vital role.

E-CVT structure

  If you look at it from the perspective of traditional transmission, the structure of E-CVTIt’s really, really simple. Many times, the more perfect things are, the simpler they are. I think this must be the truth. As a masterpiece of hybrid cars, Prius has been carrying the core hybrid technology, so the next analysis takes Toyota Prius as an example.

Ingenious conception and good economy! Full analysis of ECVT transmission

  The structure of E-CVT is very simple, only made up ofExternal gear ring(The outer gear ring here connects the No.2 motor and the output shaft at the same time) andplanetary carrier(connection) andSun gear(connected to No.1 motor), that is, the power transmission flow is:No.2 motor — External gear ring — output shaftAt the same time, due to the existence of planetary gear sets, there are also:Engine — Planetary group — External gear ring — output shaft. The following physical picture was taken from a foreign video.

  If you look closely, you can’t help wondering: Isn’t this the structure? Yes, E-CVT is made up of a planetary gear set reduction mechanism (The red box in the picture above.)。 There is no chain or steel belt in CVT, let alone the torque converter in AT or the double clutch in DCT. So, the problem is coming. . . Ahem. Can an E-CVT with such a simple structure really achieve stepless speed change? The answer is of course!

E-CVT principle

Overview:

  In fact, E-CVT is not very complicated only from the perspective of mechanical motion principle. How complicated can the motion of a planetary gear set be? What is complicated is its electronic control unit, that is, the logical principle of electromechanical cooperation. Before introducing the working principle, briefly list some noun notes that will be used below:

PCU:Power Control Unit (Power control unit) This is an essential part of a hybrid car, which contains a voltage converter and an inverter, and can adjust the output voltage of the battery pack. For example, high voltage (about 600V) must be used to supply power to the motor, and the voltage of the battery pack is up to about 200V due to the size limitation, so the transformer is essential. butThe function of inverter is to change DC to AC or vice versa.Because the high-voltage AC motor has the advantages of small size, high efficiency and large size, and the battery pack emits direct current, an inverter is necessary between the motor and the battery pack.

MG2:Namely motor generator 2, andExternal gear ringConnect.

  The engine of Prius is Atkinson engine, which is characterized by good intermediate speed performance, insufficient high and low speed performance and high energy utilization rate;

  To facilitate understanding, put a simplified E-CVT structure diagram:

  Next is the power distribution diagram.

Ingenious conception and good economy! Full analysis of ECVT transmission

  First of all, we need to be clear about a concept:Power is the product of combination with rotational speed.(power = torque × rotational speed),

  Then because there are four that canFree revolutionPlanetary gear, it can be imagined that when the gear ring is fixed (that is, the wheel is fixed), the sun gear (MG1) can only drive the planetary gear seat (that is, the engine) to rotate (that is, start the engine process) when the planetary gear rotates;

  With the rotation of planetary gears, when the ring gear (MG2) rotates forward, the sun gear (MG1) can also rotate backward. Conversely, when the ring gear (MG2) rotates reversely, the sun gear (MG1) can rotate forward again.

  For example, when the outer ring gear and the sun gear rotate in the same direction, the planetary gears can not rotate, but only revolve, thus driving the gasoline engine to rotate. When the planetary gear seat does not rotate, the ring gear and the sun gear can still rotate freely. It is precisely because of this ingenious characteristic of the planetary gear set,Only when the engine, wheels and motor are connected together can they run without interfering with each other.Therefore, the clutch structure is omitted.

  S=C×3.6-R×2.6

  In the formula, s = sun = sun gear, c = carrier = line constellation, and r = ring = outer gear ring.

  In addition, since the diameters and teeth numbers of the external gear, the sun gear and the planetary gear have been fixed, it can also be obtained according to the formula on the drawing:When the planetary constellation rotates in the middle, the torque ratio allocated to the outer ring gear and the sun gear is certain.. The specific value is about72%Allocated to the external gear (actually 2.6÷3.6),28%Allocated to the sun gear (1-72%). As long as the engine rotates to work, it will not change this basic fact.

Ingenious conception and good economy! Full analysis of ECVT transmission

  Then we all know that under a series of different working conditions, the requirements for torque are greatly changed. Traditional power vehicles need a transmission to adjust the output power of the engine. However, in this specific structure of E-CVT, because there are two motors, under different working conditions,According to the above formula. As long as the different rotational speeds of these two motors are controlled, the engine power obtained on the outer gear ring can be changed infinitely, so that the automobile can achieve stepless speed change.

  As for how the PCU of Prius can control the fuel supply of the engine and the voltage, phase and positive and negative on-off of the two motors in real time according to the running conditions of the car. The control logic involved and the data collection and processing procedures of many sensors are too complicated to be described here. Understand that E-CVT can realize stepless speed change.

Detailed explanation of working conditions

  The following analyzes the speed change process of E- one by one from various operating conditions:

I. Idle running (hot car)

  After the start command is issued, it starts (rotates forward) in an instant and drives the start. The whole process is extremely fast and smooth.

Ingenious conception and good economy! Full analysis of ECVT transmission

  After the engine is started, it runs at idle speed, and the gasoline engine drives the planetary constellation to rotate forward. Because the wheel (outer ring gear) does not rotate, the forward rotation of the planetary gear set (engine) will drive the sun gear (MG1) to rotate forward through the planetary gears. MG1 no longer receives power from the battery pack, but becomes a generator.Emit alternating current, through the inverter and voltage converter in PCU, it becomes low-voltage DC and charges the battery pack. In short, at idle speed,The whole engine is used to charge the battery pack..

Ingenious conception and good economy! Full analysis of ECVT transmission

Second, start

  After the start signal is sent, a small amount of power will be connected to the No.2 motor, and MG2 will start to rotate. Drive the wheel (outer gear ring) to start forward rotation, and the car moves slowly. When you press the accelerator pedal slightly hard, the No.2 motor will get more power and the Prius will accelerate. Because the power of No.2 motor is very high (50KW), the low speed is also very high. Under the control of PCU, the acceleration of the car is very soft.Even by MG2 aloneYou can accelerate the Prius to a considerable speed! This starting process gives full play to MG2.Low speed and high torsionTo make up for the embarrassing situation of insufficient low-speed torque of the engine.

Ingenious conception and good economy! Full analysis of ECVT transmission

  It is worth noting that if the engine is not working at this time (starting in pure electric mode), with the increase of the rotational speed of MG2, the rotational speed of MG1 will also increase rapidly. Because the speed of MG1 has an upper limit, when it reaches the upper limit, the engine is forced to start to intervene. There is a critical speed at this time. Although this speed is fixed, it is certain that the greater the intensity of stepping on the accelerator at the start, the earlier the gasoline engine will intervene (actively intervene). If you step on the accelerator all at once, the gasoline will ignite immediately.

  In most cases, MG2 can smoothly accelerate the Prius to a good speed, but in some cases, there will be a phenomenon of insufficient power. This is what the engine will pass after intervention.Driving MG1 to generate electricity for MG2.andDirectly drive the external gear to rotate to push the wheel.Two ways to output power, it is worth mentioning that these two ways can exist at the same time. As for the proportion of each other, it depends on many factors.

Ingenious conception and good economy! Full analysis of ECVT transmission

Third, small load acceleration

  When accelerating under light load, the wheels are mainly driven by MG2. With the speed of MG2 increasing, the speed of reverse rotation of the four planetary gears gradually decreases. When the speed of the gear ring is the same as that of the planetary constellation (engine), the rotation of the planetary gears stops, leaving only revolution. At this time, the planetary constellation (engine) pushes the gear ring (wheel) and sun gear (No.1 motor) through the four planetary gears that are no longer rotating, and the three speeds are consistent. MG1 continues to supply power to MG2 and charges the power battery through PCU. Thereafter, the speed of MG2 continues to increase until the vehicle reaches the target speed. At this time, the sun gear rotation speed is less than the rotation speed of the constellation.

Ingenious conception and good economy! Full analysis of ECVT transmission

Fourth, heavy load acceleration

  In the face of heavy load acceleration (such as load starting), the power of MG2 can’t keep up.Engine speed increaseEntering its economic operation range, the power of the engine is greatly improved. Because the torque increase of the engine further drives MG1 to generate electricity and the power obtained by the outer ring gear increases, at the same time, the battery pack will also supply power to MG2. Thanks to this, MG2 enters the "full firepower" mode.

Ingenious conception and good economy! Full analysis of ECVT transmission

Fourth, driving at a constant speed

  Driving at a constant speed occurs after the acceleration is completed. At this time, the Prius only needs to overcome all kinds of resistance, and the demand for power and torque is greatly reduced. After the throttle is relaxed, the speed of the gasoline engine decreases, and the speed of the gear ring (wheel) is higher than that of the planetary carrier (gasoline engine). At this time, the four planetary gears began to rotate forward. This forward rotation will drive the sun gear (MG1) to reverse.

  There is something special here, as we learned from the previous article. When the power from the engine is transmitted to the outer ring gear and the sun gear through the planet carrier, the rotational speeds of the outer ring gear and the sun gear will satisfy the following formula.

  S=C×3.6-R×2.6

  When the rotating speed of the outer gear ring is higher than that of the planetary carrier, that is, when R>C, it is obvious that S < 0, that is, it is reversed. However, if the reverse rotation of sun gear at this time is idling (without any resistance), it will rotate so fast that all the power from the engine will be absorbed by MG1 and the external gear ring cannot be driven (because it is obviously much easier to drive sun gear than to drive the external gear ring). Therefore, MG1 will need to work in the motor mode here, so that the planet carrier can’t drive the sun gear to fly at high speed and waste the power of the engine.

  But wouldn’t that be a waste of electricity? Therefore, in general, when cruising at high speed, MG2 becomes a generator to maintain the rotation of MG1.

Ingenious conception and good economy! Full analysis of ECVT transmission

  In fact, during the whole driving process of Prius, the state of acceleration and uniform driving is constantly switching. The phase of voltage and current will be adjusted by PCU according to various operation actions such as stepping on the accelerator and releasing the accelerator, and various driving conditions of the car, and the output power and rotating direction of the motor will be changed instantly, and the functions of the two motors will be switched.

Fifth, slow down

  In fact, the deceleration is relatively simple, with the engine turned off and the MG1 idling. MG2 is driven by the wheel and becomes a generator to absorb the deceleration energy of the wheel. And charge the battery pack.

Ingenious conception and good economy! Full analysis of ECVT transmission

Sixth, reverse the car

  Thanks to the large torque of MG2, the torque MG2 required by the Prius when reversing can be easily provided. The battery pack supplies power to MG2, which drives the external gear ring to reverse, and the vehicle finishes reversing.

Ingenious conception and good economy! Full analysis of ECVT transmission

  In the whole driving process of Prius, we can see that it is actually a process in which two motors and engines cooperate with each other to perfectly perform linear output under strict electromechanical conversion logic control. The basis of this perfect cooperation is the special structure of E-CVT. Because power = torque × rotational speed, the planetary gear set structure with proportionally distributed torque and infinitely distributed rotational speed enables the power of the engine to be infinitely distributed to the outer gear ring (i.e. wheels) at any time and place, thus completing all functions of the ordinary stepping gearbox!

  The following table shows the running state of each gear of E-CVT during the whole process:

  You can also refer to the following video to improve your understanding of the operating relationship between planetary gears, sun gears and external gear rings.

Prospect of E-CVT

  The appearance of gearbox was born in order to meet the different power requirements under various complex working conditions. Before it appeared, drivers needed to judge the road conditions and car conditions themselves to shift up and down in time. The advantage of this method is a strong sense of driving operation. After all, experienced drivers know what kind of power the car needs better than ECU. In addition, the advantages of simple structure, easy maintenance and small size also make the car with manual transmission have a large number of fans no matter where it is suitable.

  The appearance of automatic gearbox is actually very early, but the real large-scale application was in the 1980 s, and it was also a free ride with the rapid development of electronic technology. Because automatic transmission is not difficult, it is difficult to change the speed more accurately. In the mechanical age, technology is obviously difficult to achieve, but nowadays, more and more intelligent ECU makes automatic transmission more and more able to understand your driving intention. But even so, the automatic gearbox still has defects:There is shift clearance.Even DCT can’t realize the real "stepless speed change".

  As for the protagonist E-CVT in this paper, it can be said that it has reached the peak of the integration of electromechanical technology in the gearbox field. First of all, its logic control system is very complicated. In addition, it can effectively make up for the short board (low transmission power) of the traditional stepless gearbox, which integratesHigh power, quick response, stepless speed change and extremely high transmission efficiency.And other advantages in one. But it also has disadvantages:The support system is too complicated.We know that once any system is too complicated, the probability of problems will increase exponentially.

summary

  Let’s make a simple summary of E-CVT:

1. Very smooth, extremely smooth

2, the transmission efficiency is high

3, simple structure and small volume

  Let’s go back to the question at the beginning of the article about whether E-CVT is right or not. Let’s put it this way: If other power sources were not needed to cooperate with it, I’m afraid E-CVT technology would have unified the gearbox field long ago. It is precisely because of this "fatal" defect that it is simply tailored for hybrid models. Writing this analysis is not entirely for the sake of popular science, but I hope that everyone can learn more about this somewhat heterogeneous and unknown transmission structure and its thinking. Because I firmly believe that in the future when fossil energy is exhausted, E-CVT will finally shine!

Can Fat Donglai enter Zhengzhou after all? Yu Donglai officially responded!

On the evening of May 30th, Fat Donglai changed Yonghui’s first store to close, and Yu Donglai appeared in Xinwan Square.

Yu Donglai made it clear that the development of the same trade is too complicated, so Fat Donglai will not enter Zhengzhou market, but Fat Donglai will come to Zhengzhou in another way by changing Yonghui and other supermarkets. By transmitting its own supply chain, service concept and system to Zhengzhou peers, consumers don’t have to go to Xuchang to queue up.

Yu Donglai said: It will take one year for Yonghui to adjust to a relatively healthy state. Today next year, all stores in Yonghui will not lose money, and all employees will earn more than 4,000 yuan.

"Entrepreneurs should at least respect their employees and think about how to make our employees work and live with dignity." Yu Donglai said at the scene. "Now many enterprises in second-and third-tier cities and even first-tier cities have employees’ income of only two or three thousand yuan. Entrepreneurs still talk about benefiting employees. What are such bosses doing?"

He believes that at present, China has put forward a strategy of high-quality development, as an enterprise should respond to the national strategy. Entrepreneurs need to think about how to lead employees and lead more people to create more beauty.

According to Dahe Finance Cube, Yu Donglai’s goal for changing the first store of Yonghui Supermarket is that "the average daily revenue of Yonghui Supermarket will increase by five times after the change".

Yu Donglai said that it is estimated that the daily sales of this store will be around 800,000 yuan. "Now the daily sales is only 160,000 yuan. In the future, the daily sales will not be less than 500,000 yuan, which is estimated to be in the range of 800,000 yuan to 1 million yuan. In the future, it is possible to transform about three Yonghui supermarket stores in Zhengzhou to make Yonghui Supermarket better. " Yu Donglai said that only when everyone is constantly optimizing and moving towards goodness, there will be no competition for involution. "In the past, it was to make money and make profits. Now it is to be better than anyone, so that we can move from a competitive mentality to a friend relationship." Yu Donglai said.

Test drive the all-new Audi Q5L: adding more than just the wheelbase


The new Audi Q5L has attracted much attention. Photo by Sun Xiaomeng, a reporter from Beijing News

  ■ Car reading test drive

  

  Starting from the Q7, Audi began to use the design of the new generation of models. On July 6, Beijing News reporters participated in the new Audi Q5L media test drive event held by FAW-Volkswagen Audi in Guizhou. The new Audi Q5L after this "lengthened" has become full and mature in visual effect through the improvement of the front details. The larger hexagonal middle net and the complex and eye-catching headlight design all show the unique design language of Audi models, and the longer wheelbase enhances its market competitiveness.

  The wheelbase is lengthened and the space is increased.

  The new generation of Audi Q5L still has obvious Audi Q-series genes in its exterior design, with a large 3D aluminum intake grille and intelligent matrix headlights, expressing the Audi family’s expertise in technology.

  The new car also lengthens the wheelbase by 88mm to 2908mm, and the lengthened part is concentrated in the rear row space, which has certain advantages in the same class.

  In the rear part, the new Q5L is familiar with the previous generation of models, especially the outline of the taillights and the "clam shell" overall hatchback tailgate that continues to be used. The Beijing News reporter noticed that the "exhaust" under the bumper of the new car is only decorative, and the real double exhaust port is located on the underside of the bumper. This has become a common feature of many Audi models, and even the SQ5 has not been spared the "fake exhaust".

  In-car technology configuration improvement

  The interior texture of the new Q5L has improved. The center console shape is not fancy, simple and practical, and the technology configuration in the car has been improved synchronously.

  During the test drive, the Beijing News reporter noticed that the Q5L is equipped with a 12.3-inch full-LCD instrument and the latest MMI multimedia system with an 8.3-inch central control screen, which can provide LTE 4G network, Wi-Fi network hotspot functions, and more.

  In the high-end model, the Q5L also has more features to enhance the sense of luxury, such as the Danish Bang & Olufsen sound system, HUD head-up display system, and automatic parking.

  Fast dynamic response

  The new Q5L is equipped with the same power unit as the new A4L, namely two different power-tuned 2.0T turbocharged engines. The maximum output of the 40 TFSI model is 140 kW, and the maximum output of the 45 TFSI model is 185 kW.

  The new car is equipped with a 7-speed dual-clutch transmission code-named DL382, replacing the 8-speed automatic transmission of the old model. It is worth noting that the new car is equipped with a new quattro ultra four-wheel drive system, which eliminates the central Torson differential on the old model and replaces it with an electronically controlled multi-disc clutch. This change changes the all-wheel drive of the new Audi Q5L to a timely four-wheel drive dominated by the previous drive.

  No matter what mode, when the reporter of the Beijing News stepped on the accelerator deeply, he could feel that its power output was very strong. If it was not for the pursuit of "speed and passion", the power would definitely be sufficient.

"It’s Worth It" exposes new trailer, Hu Ge listens to Huang Lei’s unspeakable feelings for his father


1905 movie network news The film, directed by producers and writers, will be released nationwide on September 9. The film won two awards for best director and best actor in the main competition of the Golden Goblet Awards of the 25th Shanghai International Film Festival. Today, the film released an emotional preview of "Regret for Father and Son". The preview begins with Wen Shan’s confession of writing a eulogy. "I am the one who sent everyone the last journey with words," telling the client Mr. Wang’s regret for his father’s love and lack of company that he never spoke to his face.


Wang is one of Wen Shan’s eulogy clients, and his relationship with his father reveals the traditional silent relationship between father and son, which is poor in words and lack of communication. Wang expresses his love by providing his father with a comfortable life, but he also lacks his father’s company. It is not until his father leaves that he feels his father’s true appeal for love, which also makes Mr. Wang’s attitude towards his family begin to change: as a son, he has turned over, but as a father, his days are still long.


Wen Shan met various clients in the movie "It’s Worth It", listened to and deeply felt the emotions expressed in the client’s words. The communication process with the client is not only the process of Wen Shan, who wrote the eulogy, helping the client recall, sorting out the final farewell to his relatives, but also the process of the frustrated screenwriter Wen Shan being healed by the warmth of the world’s true feelings.


In addition to Mr. Wang’s family (Huang Lei,, decoration), Wen Shan’s eulogy client, as well as the Wanjia siblings (Fu Yaozhi, decoration) who also wrote eulogies for their relatives; the entrepreneur Lao Lu (decoration) who wrote eulogies for colleagues; Shao Jinsui (decoration) who asked for eulogies for netizens; and Auntie Fang (decoration), an anti-cancer expert who booked eulogies for herself. On the way to Wen Shan’s growth, there are also teachers (played) who accompany him along the way, friends who work in the funeral home, Pan Congcong (played), and keepers (played) with stories… Wen Shan achieved two-way healing with the client during the writing of these eulogies, and felt the true meaning of living happily. Wen Shan also achieved his own growth and reconciliation in the process of two-way healing.


The film has been screened at the 25th Shanghai International Film Festival and has received good reputation. When winning the Best Actor award, he said: "When an actor really falls in love with a character, he will completely surrender himself to the character, which is also my most profound experience." Audiences also praised Hu Ge’s performance: "As the absolute protagonist, Hu Ge’s performance method is very different from before, and the performance method is more immersive and delicate." "Hu Ge has completely become Wenshan itself, and it has a deeper level of expression from image to inner."


It was worthwhile.It will be released nationwide on September 9.


FAW Pentium has joined "Run" again, and the exclusive car of Running Men has been upgraded with a full "core".

In the warm spring of April, the long-awaited ace variety show "Run It" finally made a big comeback, and the new "Running Man Group" gathered again with a strong lineup. At 17:17 on April 27, starting from "Core", it was officially announced that it had crossed the border again, bringing its new model PRO to help the Running Man Group run. As the only official designated car of this season’s "Run It", the "attractive force car" PRO, which is both popular and powerful, will collide with the Running Man family. What kind of spark will attract countless fans and viewers.

The official announcement of the Extreme Speed Movement Group, "handsome, true, strong, and obvious" is irresistible

With the re-cooperation between the brand official announcement and "Run", the mystery of the first two-dimensional spokesperson, the "Extreme Speed Movement Group", has finally been unveiled. As four "wind chasers" with distinct personalities, their images are all taken from the archetypes of the characters of the Running Man Group, and they combine the four cores of PRO "handsome, true, strong and obvious" with the characters of the brothers to create a unique trendy and cool animation image, which has been well received by netizens.

Beauty is Justice – Extraordinary Charm Tiger

Popular idol Cai Xukun incarnated as a charm tiger, stylish and soulful. Charm Tiger is like a guy full of positive energy, and is the face of the team. Like PRO, the light and shadow polyline design makes the lines more three-dimensional, and the details are not sloppy at all. Not only is the appearance more layered, the double flying swallow shape gallops on the runway like flowing clouds and flowing water, showing the trend and cool charm with a face and a han.

Safety is the truth – guarding the cow with a long rainbow

Li Chen, a superpower, turned into a guardian cow and instantly escaped the gravity of the earth. Running all the way, someone always has to stand up in a critical moment. As the strength of the team, the guardian cow has a stable concentration like a rock, just like the "Car Brothers" PRO has a super high-strength cage+ Five-channel force transmission structure, carefully designed and optimized energy absorption area, with a strong sense of security to support the running boy group to run hard, giving each family member enough strength and confidence to challenge the illusory, true and reliable strength.

Speed – Resolute Wind Chaser Leopard

The master Zheng Kai turned into a wind chaser leopard and overtook the opponent in the corner. As a vitamin in the team, the wind chaser leopard is a young man who is always full of vigor and energy. The general speed perfectly matches the PRO upgrade of 1.5T. Strong power escorts the running man group at any time, and the energy goes straight to the sky. The blessing of light weight and high precision, the corner overtakes the opponent without fear of resistance, and realizes free galloping in all road conditions, flying like the wind.

Wisdom shows ingenuity – Confidential Meow

As the only girl in the team, it is also the wisdom of the team. Confident Meow has super intelligence, talent and intelligence to deal with a variety of thorny problems, and at the same time, there is no lack of kindness. With the PRO holographic intelligent control system, it supports voice interaction and visual interaction. The Zhilian system is ingenious, and the human-computer interaction is more warm. It is not alone on the run, adding warmth to the running man family.

The recording of the program is imminent, and it is expected to set off a "tear brand" war in FAW

The appearance of the cool image, the new character setting, and the appearance of the "Extreme Speed Movement Group" not only triggered the attention of the whole network, but also hinted that the dust of the cooperation contract with "Run" has settled. The new entry of the "attractive force car" PRO, how will it help the running man family "hang up" all the way and play more challenges? I believe the first stop will definitely give the audience a satisfactory answer.

It has to be said that the filming location of each issue of "Run It" has attracted much attention from fans. Looking back on the first stop of "Run It" last year, the members of the Running Men Group joined hands with 35 pairs of Angang father and son to carry out a blood-blooded showdown, showing their hard-core strength. At the oil field station, the Running Men brothers turned into college students and fought against aliens for oil. While experiencing the life of Angang employees, they paid tribute to the "iron man spirit" of the oil field. During this period, the T family hard-core model T77 also left a deep impression on the audience with hard-core black technology in the program.

This year, the newly upgraded PRO returns to "Run" as a hardcore guest, which can’t help but arouse countless fans’ speculation. Will this season’s Running Men Group come to this same hardcore, the birthplace of the old partner, and explore the unique cultural heritage and new appearance of "Detroit of the East" in the name of running? At the same time, fans are also more looking forward to what kind of spark will collide between the brothers’ brave and never-give-up spirit and China’s industrial inheritance, innovation and enterprising spirit? Let’s wait and see.

For the new journey that is about to begin, how can PRO, who has always been unafraid of challenges, "become one with" the Running Man Group faster, and skillfully use its advantages to help family members solve problems and complete the mission of helping run? We look forward to PRO giving the program a different kind of new excitement.

Interview with Zong Qinghou: The company has tens of billions of cash deposits to deal with the crisis, the epidemic has a great impact on the economy, and it is crucial to stimulate 1 billion domesti

  Guide: How big do you expect the impact of the epidemic on the domestic economy in 2020? Zong Qinghou said that the impact is very large, and the key is that the global epidemic is still evolving. But he also believes that to boost the economy, only to stimulate domestic demand. China is a big market with a 1.40 billion population. As long as domestic demand goes up, it will be no problem to develop at a high speed for many years.

  During the cold winter, Wahaha, which had always been stable, became "radical".

  On April 28, at the headquarters of Wahaha Group, No. 160 Qingtai Street, Hangzhou, in this simple six-story building, Zong Qinghou once again accepted an exclusive interview with the 21st Century Economic Herald reporter to explain his thoughts on the epidemic and e-commerce.

  At the moment of crisis under the epidemic, the biggest problem many companies face is insufficient cash flow, which cannot survive the day of retaliatory consumption after the epidemic is over. This problem does not exist in Wahaha.

  In February, when it was completely shut down, Wahaha lost only 100 million yuan. But its bank account was still sitting on more than 10 billion yuan in cash. In this way, Wahaha could be shut down for 10 years without going bankrupt. In fact, Wahaha restored 80% of its production capacity in March, and its sales in April had increased by 30% compared with the same period last year.

  So when the real economy was full of grief, many companies were laying off staff and cutting wages, and shrinking the front line, Wahaha took the opportunity to expand aggressively. It announced that it would invest billions of yuan to launch four new e-commerce platforms, and "bottom fishing" talents, to recruit 100,000 social retailers.

  In 2018, Zong Qinghou, chairperson of Wahaha Group, summed up his business philosophy in an exclusive interview with the 21st Century Business Herald reporter as "focus on the main business, run in small steps". The so-called "small steps" refers to being careful in decision-making, expanding in small steps, and immediately retreating to stop losses if you find something wrong. "Run" refers to acting quickly when an opportunity arises, seizing the opportunity, and not hesitating.

  Among China’s private entrepreneurs, Zong Qinghou is very special. He has adhered to two principles for decades: one is not to do "quick money" industries such as finance and real estate, and the other is not to operate in debt. Even if it takes tens of billions to launch four e-commerce platforms in one fell swoop, he still insists on all investment from equity funds.

  Wahaha has developed from the distribution department of a school-run enterprise to a leading enterprise in China’s beverage industry with total assets of nearly 40 billion yuan. It has persevered and changed with time. The environment has changed, consumers have changed, and so has Wahaha. Is Wahaha also stepping on the node this time when it enters e-commerce?

  

  Responding to the epidemic: Wahaha has more than 10 billion cash deposits

  "21st Century": Have you measured Wahaha’s cash flow? Is it safe?

  Zong Qinghou: It’s very safe. We still have more than 10 billion yuan in cash deposits in the bank.

  "21st Century": How much is the company affected by the epidemic, how much has the income decreased compared with the same period last year, how is the resumption of work and production, has the order been affected, and has there been any layoff and salary reduction?

  Zong Qinghou: We lost almost 100 million yuan in February this year. Because we can’t start work, we still have fixed expenses. We have three production bases in Hubei Province, in Wuhan, Yichang and Hong’an. Wuhan is the last base to resume production.

  None of Wahaha’s tens of thousands of employees were infected, so Wahaha was one of the first companies to resume work. Our production capacity returned to around 80% in March. Sales in April increased by 31% compared with the same period last year, and orders increased by 21% compared with the same period last year.

  Instead of layoffs and salary cuts, Wahaha is preparing to expand its recruitment significantly. First of all, Wahaha has recruited more than 1,000 high-level talents from around the world in the two directions of "big health" and "intelligent manufacturing", including nutritional function support engineers, health food research and development engineers, etc. Secondly, our new e-commerce platform will also recruit 100,000 social retailers. We want to find 100,000 newly graduated college students, each of whom will give him 100,000 loans to be our health care product distributors.

  21st Century: Why did sales increase by 31% year-on-year in April? Is it because of retaliatory consumption after the epidemic?

  Zong Qinghou: No, revenge consumption did not appear. Mainly because we prepared earlier and acted quickly. Sales growth was mainly achieved by expanding sales through various operating methods.

  "21st Century": Wahaha is not greatly affected by the epidemic?

  Zong Qinghou: Now the overall market has shrunk due to the impact of the epidemic, but it is expected to rebound after the epidemic has passed. So now we are more proactive and seize the opportunity to seize the market.

  For example, if offline promotion is not possible during the epidemic, we will require distributors, wholesalers, and retailers to establish WeChat groups and hold promotion meetings in the WeChat groups. In addition, we are also looking for partners to deliver products to communities, government agencies, enterprises, and institutions.

  E-commerce layout: resolutely do not burn money to buy traffic

  "21st Century": Is the idea of building an e-commerce platform before or after the epidemic?

  Zong Qinghou: It was there before the epidemic, but the epidemic made this idea more bold and clear. Before the epidemic, I just wanted to build an e-commerce direct sales platform for health products, and promote the combination of online and offline channels to create a digital marketing platform. After the epidemic, I decided to build four.

  "21st Century": So before the epidemic, Wahaha only wanted to build a health care product e-commerce platform, but after the epidemic, Wahaha decided to launch four e-commerce platforms in one go?

  Zong Qinghou: Before the epidemic happened, we wanted to build an e-commerce platform for health products in the vertical segment. Wahaha’s main business is from "safety to health", so it hopes to produce healthy food and health food to meet the needs of consumption upgrading. If you want to build a new health product sales channel, the e-commerce channel is still relatively easy. And there is no e-commerce platform dedicated to selling health products.

  The other is the food and beverage sales platform. We integrate distributors, wholesalers, and retailers into this platform, making it more convenient for them to place orders and ship goods. At the same time, we can also sell food and beverage products for other companies.

  Our offline channels are already very strong. Now export enterprises are blocked from exporting. All countries in the world are affected by the epidemic, which is giving rise to the global financial crisis and economic crisis. So what should domestic export enterprises do? Export cannot be done, and the domestic market competition is too fierce. Our self-built e-commerce platform can help some export enterprises solve sales.

  Cross-border e-commerce platform. Due to the upgrade of domestic consumption, we import some foreign high-quality products and bring some consumption back to China. The fourth platform is Habao Amusement Park, an online platform dedicated to young people’s communication, sharing and shopping.

  We are preparing to officially launch the other three platforms during this year’s "618" e-commerce festival. Cross-border e-commerce platforms will not be launched until the second wave due to the global epidemic.

  "21st Century": The traffic dividend period of the e-commerce platform has passed. The biggest problem with the self-built platform is where does the traffic come from? Can Wahaha’s brand extension be supported as an e-commerce platform?

  Zong Qinghou: On the issue of traffic, I am determined not to burn money to buy traffic. Our platform mainly helps factory direct sales. On the one hand, we can prevent counterfeiting and shoddy products, and on the other hand, we can get fairer and more reasonable prices by skipping the intermediate link. Health product e-commerce platform We want to recruit 100,000 entrepreneurs to be retailers.

  The food and beverage e-commerce platform should incorporate the joint sales network that has been built over the past 33 years, covering nearly 10,000 dealers, hundreds of thousands of wholesalers, and millions of sales end points, so that every offline store can become an e-commerce warehouse or transfer station, and every in-store salesperson is a delivery person. Like capillaries, it penetrates into counties, towns and villages across the country, and distributes products to the whole country at the fastest speed and lowest cost.

  "21st Century": Throughout the relationship between manufacturers, it has always been a game. It is difficult for a company to be both a "factory" and a "business" at the same time. Wahaha has crossed the border from factory to business this time. Are you ready? Can the original system, products and operation details match?

  Zong Qinghou: Our e-commerce platform is a brand-new sales channel established online, which will not touch the original offline price system.

  "21st Century": Hundreds of thousands of wholesalers, millions of sales end points, what do you think of your own food and beverage e-commerce platform?

  Zong Qinghou: It has no impact on dealers, and there is no conflict. It is more convenient for them to place orders through this platform, and it can also increase sales for them. It is impossible for me to destroy my original offline basic dealer channel for new e-commerce channels.

  "21st Century": In the past, you said you would neither resist nor embrace, but now you have built your own platform to actively embrace e-commerce. What has prompted your change?

  Zong Qinghou: I have never resisted e-commerce. What I resisted was burning money to buy traffic and counterfeit and shoddy products to disrupt the market. Since the outbreak of the epidemic, roads have been closed everywhere, cities and communities have been closed, and a large amount of consumption has been transferred from offline to online. Now consumers’ online shopping habits have been formed. So the general trend cannot be violated. But with the easing of the epidemic, consumers’ offline consumption trend has rebounded. People always have to go out, and it is impossible to rely on online shopping at home forever.

  "21st Century": How much will be invested in these four platforms in total?

  Zong Qinghou: About tens of billions.

  "21st Century": Where does the money come from? Is there a bank loan?

  Zong Qinghou: No, all are equity funds.

  "21st Century": Bank presidents will cry when they hear it.

  Zong Qinghou: No, the governors also like us very much. Because we solved the deposit index for him.

  "21st Century": Are you responsible for these e-commerce platforms? What is your main focus now?

  Zong Qinghou: I am in charge of the preparation now, and I will definitely hand it over to the management later. I have a lot of things to do now, developing health care products, purchasing equipment, building factories, and so on.

  "21st Century": The crisis is the most testing time for the company. In addition to rebounding after the epidemic is over, what measures has the company taken to save itself? What other expansion plans does Wahaha have this year?

  Zong Qinghou: Focusing on our e-commerce platform, we are now establishing our own health care product production base.

  21st Century: Will entering the e-commerce platform help Wahaha’s digital transformation from traditional manufacturing to production, management and sales?

  Zong Qinghou: In fact, Wahaha has been doing digital transformation for a long time, and the digital economy is the No. 1 project in Zhejiang Province. Wahaha introduced foreign advanced production lines in the early days, and later introduced stand-alone machines, integrated automated production lines, and now designs and plans its own smart factories.

  A few years ago, we have felt that industrial robots will be an important direction for the development of artificial intelligence manufacturing. Many traditional manufacturing companies purchase equipment, but Wahaha chooses to develop independently. This is Wahaha’s most important industry after food and beverage. Wahaha has become the only enterprise in the domestic food and beverage industry with the ability to develop, design, and install and debug equipment by itself. Now it is mainly for self-use, and it will go to the market in the future.

  Talking about the economy: Boosting domestic demand is fundamental

  21st Century: How big do you expect the impact of the epidemic on the domestic economy in 2020?

  Zong Qinghou: It has a great impact. The key is that the global epidemic is still evolving, so it has a great impact on our exports. The "troika" of development in the past – exports, investment, and consumption – can’t rely on exports and investment now. I think to boost the economy, only by stimulating domestic demand. China is a big market with a 1.40 billion population. As long as domestic demand goes up, it will be no problem to develop at a high speed for many years.

  The consumption upgrade of China’s 400 million middle class has driven the rapid development of the domestic economy in the past few years, but now they have consumed everything they can consume at home, and then they have gone abroad to spend, such as buying luxury goods, traveling abroad, and sending their children to study abroad.

  The key now is to stimulate the domestic consumption of the remaining 1 billion people, and to pull back some of the consumption of the 400 million middle class abroad, such as opening duty-free shops in China.

  Aiming at the vast rural market, is the state considering restricting the import of agricultural products (000061, stock bar), because foreign imported agricultural products are cheaper than domestic farmers. Raise the price of agricultural products to encourage some migrant workers to return to their hometowns for employment and increase their income.

  There are also tax cuts for enterprises, such as reducing corporate income tax by 5% -10%, but the limited part of the reduction must be used to increase employees’ wages, otherwise it will not be reduced for you. In this way, the income of urban residents will increase. The increase in income of urban and rural residents will naturally pull consumption. Now young people’s consumption concepts have also changed. They are willing to spend and dare to spend. As long as their income increases, consumption will naturally rise.

  "21st Century": Consumption coupons are now being issued everywhere. What do you think of this measure?

  Zong Qinghou: Although the government now has various relief for enterprises, such as loans, it can’t be released at all, because enterprises have resumed work and production, but there are no orders, no demand, and they don’t know what business to do with the money they borrowed, so some of them have flowed into real estate speculation. So the key to boosting the economy now is to stimulate domestic demand. The government has tried its best to help enterprises tide over the difficulties, but there must be demand at the source to have orders. No policy is useless without demand.

  21st Century: After this epidemic, many private enterprises are reflecting on whether their business models have the ability to resist risks. What do you think?

  Zong Qinghou: Many private enterprises, especially small and medium-sized private enterprises, have closed down. In addition, there are some enterprises that have over-invested and over-indebted, and it is difficult to survive now. The cash flow is stable, and I think it can still survive.

  21st Century: How do you think private enterprises should be supported?

  Zong Qinghou: Now the government is very supportive of private enterprises. I think the key is to stimulate domestic demand, so that the people (603883, stock bar) have the ability and willingness to consume, so that private enterprises can open their doors to do business.

  Interview Notes | Wahaha’s tens of billions of deposits account, what do banks think?

  There is a controversial voice about Zong Qinghou in the outside world that is "conservative".

  After many interviews, it was discovered that there is actually a little-known story behind the controversy. Briefly, in 2014, Zong Qinghou publicly criticized the negative impact of e-commerce on the real economy, which caused controversy.

  In fact, he is not against ecommerce. "I used to be dissatisfied with them [ecommerce] because I was not satisfied with burning money to buy traffic and selling fake and shoddy products," he said. "I am not against ecommerce, and I think ecommerce should go deep into the countryside to help farmers sell their products, because farmers’ information is relatively closed, and increasing production does not increase income."

  Due to the large weight and small added value of Wahaha’s drinking water products, his previous caution towards e-commerce is not difficult to understand.

  But in fact, Wahaha joined hands with Alibaba to launch a shared service credit kiosk in September 2017, launched "Habao Amusement Park" in December 2018, and launched product promotion on Douyin, WeChat, Weibo and other platforms in 2019.

  Although he is a 75-year-old, he remains constantly alert to changes in the market and is willing to embrace innovation when he perceives changes and finds possible solutions.

  He is not a stubborn old man who does not embrace change and modern technology. Wahaha’s factory building has China’s first intelligent beverage production line. His bookshelves are densely packed with maps, full of maps marking the markets he has visited on the spot, and his footprints are all over China’s urban and rural areas.

  In recent years, Zong Qinghou has expanded the scope of investigation on the map to include the United States, Israel, and others.

  An epidemic in 2020 dragged the world into the cold winter of economic recession. He also saw that since the epidemic occurred, due to road closures, cities and communities, a large amount of consumption has shifted from offline to online. He knows that the general trend cannot be violated.

  Zong Qinghou’s shaping of Wahaha is far from as simple as leading the crowd to win countless battles and wars. In 1988, he independently developed Wahaha nutrient solution to complete the original accumulation, in 1991, he merged with the old state-owned factory to achieve large-scale operation, in 1996, he and Danone jointly introduced foreign capital for their own use, and in 2005, he launched the Nutrition Express with a cumulative output value of more than 100 billion yuan. To bottled water, Zong Qinghou’s every step is stepping on the node of the times. This time, he launched four e-commerce platforms in one go. Is he also stepping on the right rhythm?

  But no matter whether it is accurate or empty, it is Zong Qinghou and Wahaha who benefit or suffer.

  From the institutional side, the billions that Wahaha is prepared to invest this time are all its own real money, without any money from investors or credit from banks. For consumers, there is one more choice and channel, which is usually good for consumers.

  Wahaha is another "extreme" compared to companies that are overextended and mired in debt crisis. It has never left its main business of beverages. Except for the early days of its establishment, it has insisted on not borrowing a penny of foreign debt for more than 30 years. Therefore, Wahaha has been questioned as "conservative" in the past.

  But fast is slow, slow is fast. Businesses are like people, sometimes ill, need to think about how to improve their own immunity?

  In terms of industry and finance philosophy, Wahaha has persisted in not lending a penny for decades. On weekdays, it seems that such enterprises are too "conservative", but in the cold winter, it is a precious "immunity" that allows enterprises to withstand the next spring. Reasonable cash flow is life infra for enterprises.
