Editor’s note:

On April 7, 2022, Pudong Hospital was transformed into a designated hospital in COVID-19 to treat COVID-19-positive hemodialysis patients. Dr. huimin jin, doctoral supervisor of Fudan University and director of the Department of Nephrology of Pudong Hospital, and his colleagues stuck to their posts in a special period and fought day and night to save many hemodialysis patients.

The following is his medical diary:

April 26, 2022

The 20th day of the designated hospital.

How time flies! In a blink of an eye, I have been in charge of hemodialysis patients in designated hospitals for 20 days. Although some have returned to the community after discharge, there are still patients who are constantly new and seriously ill. Every morning, like a war, it is necessary to focus on the seriously ill patients and decide which patients need bedside dialysis, and the patients whose condition is relatively stable will go to the hemodialysis room for dialysis. The doctor’s advice for hemodialysis should be made on the same day, and the corresponding ward should be informed. Checking nucleic acid is also an important task, which is the standard to judge whether a patient can leave the hospital. The first batch of medical staff in the hospital have changed rooms, but all our nephrologists are in the first batch, and there are no redundant doctors to change with us, so we must continue to work.

Originally, the work has been on the right track, and everyone is proceeding in an orderly way. At the same time, we hope to treat more COVID-19-positive hemodialysis patients. However, this calm mood was interrupted by a sudden notice yesterday afternoon. The hospital asked all positive patients in our hospital to be transferred to other designated hospitals the next day (today) in order to make room for bleeding and provide treatment for more negative hemodialysis patients. So, several doctors filled in all the information of patients to be transferred, wrote the transfer summary and transfer receipt …… and arranged dialysis for hemodialysis patients this morning (Tuesday).

Dr Yang Xiuhong.

After Dr. Yang took over from the night shift, he contacted each ward about dialysis this morning, so as to ensure that after dialysis, the burden of doctors in the next receiving hospital will not be increased, and it is hoped that there will be no more dialysis for a long time and emergency hemodialysis will be needed in the new hospital. Today, all doctors and hemodialysis nurses arrived at their posts during the day to arrange dialysis and transfer to other hospitals. The head nurse of nephrology repeatedly checks the patient information to avoid information errors or missing any hemodialysis patients, and at the same time, she personally checks in the ward to do a good job in the ideological work of each patient’s cooperation with the transfer. Dr. Bao and Dr. Zhang are responsible for the guarantee of bus transshipment, and personally pay full armed to accompany patients to the corresponding hospitals.

The work in designated hospitals should have ended here. According to the regulations, it should be 7+7 (isolation for 7 days+isolation at home for 7 days), but our team can only rest for one week, and other COVID-19-negative patients are waiting for us. I would like to thank all the friends of our hemodialysis team here. Without your support and dedication, everything would be impossible, and it is still vivid to dispatch emergency bedside dialysis every night. ……

List of nine doctors: huimin jin, Gu Huifang, Gu Yanhong, Zhou Dongchi, Zhan Xiaoli, Fu Shunkun, Yang Xiuhong, Bao Wenjing and Zhang Hua.

Li Li and Lai Bihong, head nurses of nephrology and hemodialysis room. Finally, I would also like to thank Shen Li, the benchmark nurse of hemodialysis, for building a WeChat group for our team-Left-behind Hemodialysis Desperate Saburo. In this group, many important rescues are issued and executed from the group. It may not be appropriate to call Saburo Desperate. There are only three male doctors, and the other doctors and nurses are all women, but it doesn’t matter. Everyone just works hard or Saburo Desperately.

After nearly a month’s treatment of hemodialysis patients in a closed community and 20 days’ experience in a designated hospital, the biggest change is that the hair of our female doctors and nurses in charge of hemodialysis is dry and forked, and half of my own white hair is now completely white. This is the biggest change during the epidemic, and this change will continue. I don’t know when it will end. Let’s experience the feeling of home. Tomorrow will be a 5+2 rest. Tomorrow is also our doctor Yang’s birthday. Her greatest wish is to have a braised pork, but such a simple wish is hard to come true, because we can’t go home. I have promised her that I can let her eat braised pork every day after the epidemic is over.

April 17, 2022

The 11th day of the designated hospital.

Seven o’clock. The epidemic in Shanghai began in mid-March, and it has been a month now.

Our young doctors have experienced too many things that have never been touched before, and they all feel physically and mentally exhausted, and they feel like they are collapsing at any time.

Dr. Zhang Hua is one of the young doctors. Today, I ended my diary with Dr. Zhang Hua’s essay:

When I left home, my little grandpa couldn’t shout clearly. Now he can recognize Arabic numerals, and he has been fighting the epidemic for 42 days in the blink of an eye. I entered the cabin at 2 am last night, and more than eight hours have passed since I came out. I have always felt that some patients are pitiful and always want to be perfect, but there are too many poor people in the world. Classmates say you always pity others. Does anyone pity you? Yes, we are also the poorest people. We always want to protect others as much as possible, but who will protect us? From the first closed-loop week, sleeping in hospital beds and camp beds to living without a fixed place, we have been persisting and persisting.

One day it happened that I was on duty 24 hours a day. At last, after everyone left, the ward was empty, except for the noisy voice of the construction team. I felt scared alone in the duty room. Our patients on the 13th floor temporarily merged into 15A, but the doctor on duty did not have a foothold in 15A, so I went to the 13B duty room for one night.

Later, I heard that the hospital was going to become a control area. Area A was the remaining negative patients, and Area B was the patients from the control area. Later, the hospital arranged a hotel for us, and we finally ended the days of moving around. Slowly, the number of patients in the control area increased, and later, other hospitals transferred a group of patients to our hospital overnight, and some medical staff fell down because of their busy work.

This period of time is the most difficult time in our department. We have to take care of patients across several wards, and there are constant emergency consultations and hemodialysis patients in the middle of the night. The most impressive time for me was that I invited 5-6 urgent consultations in the emergency room one night, which was equivalent to that I hardly slept in the middle of the night. In the most difficult time, only three doctors in our ward were on duty 24 hours a day. Later, there were more and more emergency cases and more and more serious cases. Dr. Fu is our big brother. He shoulders the burden of the control area and consultation. He takes care of all the serious first-aid patients in advance. We three little guys are in charge of the ward, and Director Jin takes the initiative to take the fourth shift of hemodialysis (equivalent to 24-hour round-the-clock rotation in the hemodialysis room).

Because recently, many people can’t get dialysis treatment in time because of closure, and some of them have not had dialysis for 5-6 days, and their lives will be in danger at any time. For them, Director Jin opened the fourth hemodialysis class without hesitation, so we maintained it for some time. Thank you, Brother Fu, for silently taking on so much for us, because he has to keep shuttling through the sealed control area, emergency room and fever clinic (some patients have no nucleic acid reports), and he can only bite the bullet to save his life. Our brother Fu finally fell down. Yes, this is our life. I hope that the epidemic will end as soon as possible, that we will return home as soon as possible, and that our son can recognize his mother … "

May 4, 2022:

Today is the first day of the change from positive to negative. After a short week’s rest, the original dialysis room was completely sterilized, and the first batch of patients were ushered in after many sampling inspections passed. Most of them are our old patients, and everyone is very happy to meet again. It is also orderly to enter the hemodialysis room in the morning, and most of them have 24-hour nucleic acid negative results. Individuals who do not have 24-hour nucleic acid also communicate with patients and their families, and immediately contact the neighborhood Committee to complete the nucleic acid test as soon as possible after returning.

Jin Yisheng examined the patient.

At 5: 30 in the evening, the third class of patients arrived and met another patient who needed temporary deep vein catheterization due to internal fistula occlusion. With the joint efforts of the Deputy Director of Vascular Surgery and Dr. Zhou of Nephrology Department, the catheter was successfully placed and dialysis began immediately. Today, three classes of dialysis, Nephrology dispatched nine doctors, cooperated together, and the division of labor was clear, and the dialysis of nearly 200 patients in three classes was completed in an orderly manner.

Today, the weather is fine, and the sun is shining brightly during the day, but our medical and service staff still need to put on white clothes, and they are already sweating before they work. The third nurse kept calling for heat after getting on the plane, but there was no way but to endure it. I hope these days will end as soon as possible.

The happiest thing today is that our doctor Fu has recovered. He is in the third shift today, and his spirit is very good. Together with him and Dr. Yang, I checked the patients in the third shift well. Dr. Fu particularly emphasized one patient. This patient is an old patient in our center. Last night, he went to Chuansha People’s Hospital because of chest pain. In the emergency department, he checked his electrocardiogram and myocardial enzymes, all of which were abnormal, but the patient refused to be hospitalized. Dialysis happened to consult Dr. Xiao Fu again this evening. Dr. Xiao Fu patiently and carefully looked at all the tests of the patient and thought that acute myocardial infarction could not be ruled out. He suggested that the patient go to Chuansha Hospital immediately after dialysis tonight, because the emergency room of Pudong Hospital was temporarily closed, and the hospital was a designated COVID-19 positive hospital. Everything is for the safety of patients, and Dr. Xiao Fu has brought the concept of our department to the extreme. This is our work style, and we praise such doctors.

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?

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.

  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.

Ingenious conception and good economy! Full analysis of ECVT transmission

  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.

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!

General Administration of Market Supervision: Ten Characteristics of Consumer Complaints in 2022

  Cctv newsAccording to the website of the General Administration of Market Supervision, in 2022, the national market supervision departments received a total of 29.4077 million consumer complaints, reports and inquiries through the national 12315 platform, telephone, fax, window and other channels, with a year-on-year increase of 23.5%. Among them, there were 13,103,800 complaints and 4,722,300 reports, which saved economic losses of 4,519 million yuan for consumers and effectively protected their legitimate rights and interests. It mainly presents ten characteristics:

  First, the acceleration of consumer complaints, the recovery and expansion of consumption needs balanced development.

  From the trend of the past three years, due to the cross-regional expansion of platform economy, the cross-regional flow of population capital and the cross-regional allocation of market factors, the consumption of Guangdong, Zhejiang, Shanghai and Beijing is accelerating. There is a positive correlation between the number of consumer complaints and the level of consumer activity. The proportion of consumer complaints in the four provinces and cities in the country has increased from 31.8% in 2020 to 45.16% in 2022. To some extent, the accelerated gathering of consumer complaints reflects the unbalanced development of the supply side of consumption, so it is necessary to further restore and expand consumption in the central and western regions and promote higher quality and more balanced development.

  Second, recover the loss of over 10 billion yuan, boost confidence and release vitality.

  In the past three years, in the face of the impact of the epidemic, the downward pressure on the economy and the impact of the international situation, improving the consumption environment, stabilizing consumption and promoting consumption have become important supports for stabilizing the economic market and safeguarding people’s livelihood and well-being. Market supervision departments at all levels have handled a total of 74.5229 million complaints, reports and consultations, recovering economic losses of 14.472 billion yuan for consumers, effectively defending consumers’ legitimate rights and interests, and protecting consumption power and economic endogenous motivation. We will strengthen the maintenance of commodity services concerned by the masses. For example, the mediation success rate of fiber products, medical devices, production, maintenance and repair services has increased significantly compared with the previous year, with an increase of 15.51, 13.15 and 12.26 percentage points respectively.

  Through the continuous evaluation of "five-level circular linkage", the disposal efficiency of the national 12315 platform has been greatly improved. The timely handling rate of complaints and reports was as high as 98.99%, an increase of 12.55 percentage points; The highest satisfaction of the masses is 4.74 points (out of 5 points). At present, the platform has accumulated 16.0108 million registered users, with an average annual growth of 3 million, and has become a consumer rights protection platform trusted by the people.

  Three, rapid response, strong disposal, complaints and reports of epidemic-related materials fell rapidly.

  After the promulgation of "Article 20" and "New Article 10", the focus of epidemic prevention shifted from prevention and control of infection to medical treatment. The demand for epidemic-related drugs and medical supplies surged, the supply was not smooth, the price fluctuated abnormally, and product quality problems frequently occurred. At one time, the number of related complaints and reports increased by spurt. From November 10, 2022 to the end of 2022, the national 12315 platform received 241,100 related complaints and reports, up 3.88 times year-on-year, 2.95 times quarter-on-quarter, and the highest peak reached 19.5 times. Among them, there were 141,800 complaints and 99,300 reports, recovering economic losses of 4,981,700 yuan.

  The market supervision department responded quickly, launched a special campaign to stabilize the price and guarantee the quality of epidemic-related drugs and medical supplies at the first time, promptly checked the complaints and reports of epidemic-related drugs and medical supplies, and fully protected the health and safety of the people, with a total of 12,900 cases filed. As of February 10th, the reports on epidemic-related prices, unfair competition and advertisements, online transaction supervision, product quality, and the production and circulation of drugs and medical devices have dropped by 99.14%, 87.87%, 73.89%, 88.35% and 87.79% on an average daily basis, and the demands for epidemic-related drugs and medical supplies have returned to daily life, and the market order tends to be stable.

  Fourth, the downward pressure on the economy has increased, and after-sales problems such as non-delivery and non-refund have become more prominent.

  In 2022, the national market supervision department accepted 13.1038 million consumer complaints, a year-on-year increase of 43.84%, and the growth rate was enlarged compared with 2021. From the complaints, there were 2,987,000 pieces of quality, 2,489,600 pieces of after-sales service, 1,159,100 pieces of contract and 1,090,600 pieces of food safety, accounting for 58.96% of the total complaints. Among them, the problem of after-sales service grew fastest, and the masses reflected it most strongly, with a year-on-year increase of 57.67%.

  After-sales service status is directly related to operators’ confidence and expectation. Affected by the epidemic, the problem of after-sales service has been highlighted. Consumer demands mainly focus on non-refund, non-delivery, non-performance of the "three guarantees" commitment, non-implementation of the seven-day unreasonable return obligation, and untimely delivery. From the perspective of commodity categories, it is mainly concentrated in mobile phones, shoes, coats, furniture and automobiles, accounting for 25.61% in total; Printed matter, dairy products, computer peripherals, air conditioners and luggage increased by 154%, 120%, 98%, 98% and 90% respectively.

  Fifth, the proportion of commodity complaints increased, and the consumption of new energy vehicles was short-lived.

  In 2022, the national market supervision department accepted a total of 8,623,200 commodity complaints, accounting for 65.81% of the complaints, up 4.37 percentage points from the previous year; There were 4,480,600 service complaints, accounting for 34.19% of the complaints. The increase in the proportion of commodity complaints reflects the prominent product quality problems under the downward pressure of the real economy. Among them, the top complaints are: ordinary food, clothing, shoes and hats, household items, household appliances, transportation and communication products, accounting for 58.43%. The top service complaints are: catering, accommodation, sales, Internet services, culture, entertainment and sports, beauty salons and baths, accounting for 46.37%.

  It is worth noting that with the rapid increase in the penetration rate of new energy vehicles, consumers’ requirements for quality are also constantly improving. In 2022, the platform received 16,000 complaints and reports about new energy vehicles, a year-on-year increase of 62.84%. Among them, contract problems, quality problems and false propaganda problems grew rapidly, increasing by 126.33%, 77.35% and 75.65% respectively. Consumer demands focus on: imperfect after-sales service, failure to fulfill the "three guarantees" commitment; Sudden flameout, oil leakage, abnormal engine sound, brake steering failure and battery module damage during driving; Publish false information, induce consumers to sign unfair format clauses, and reduce the responsibility of car companies.

  Six, new consumption hotspots are constantly emerging, and the accompanying consumer disputes are rising.

  In recent years, "new consumption" is becoming the "accelerator" of economic development. While meeting the diversified needs of consumption, some new situations of infringement and new problems of rights protection are gradually exposed, reflecting the new pain points of consumer rights protection.

  In 2022, new model problems such as digital collection (NFT) rose, making supervision more difficult, with 59,700 related demands (only 198 in the previous year), mainly focusing on non-delivery, non-refund, malicious price gouging, high handling fees, and arbitrary closure of consumer accounts. Under the craze of "blind box", consumer demands reached 41,400 pieces, up 61.72% year-on-year. IP cross-border co-branded products set off a buying frenzy, with 38,100 related demands, up 66.96% year-on-year. Some merchants took the opportunity to raise prices, but the problems of uneven product quality, fake and shoddy products, delayed delivery and lack of after-sales service were outstanding. Behind the fiery outdoor sports such as camping, the demands for sunscreen products and mosquito-repellent products increased by 99.12% and 149.62% respectively. Ice and snow sports are popular, but the related demands are as high as 8677, up 60.51% year-on-year. The quality problems such as ski clothes and skis are outstanding, and the tickets, deposits and safety issues of ski resorts need urgent attention.

  Seven, online consumption continues to escalate, and consumer satisfaction still needs to be improved.

  With the continuous development of e-commerce in China, the epidemic situation catalyzes online consumption habits, and the online shopping field ranks "half of the country’s consumers’ demands". In 2022, the online shopping demand increased by 56.38% year-on-year, which mainly has three characteristics:

  (1) The format of "cloud consumption" has expanded rapidly, and complaints have grown rapidly.

  Various "cloud consumption" modes, such as live delivery, cross-border e-commerce, fresh e-commerce, online shopping, online entertainment, and private kitchen customization, have emerged, which has become a bright spot in the growth of weak consumption last year, but related demands are also rising. There were 220,900 requests for live broadcast with goods, up 1.15 times year-on-year and 5.01 times higher than that in 2020. There were problems such as no products, shoddy products and false propaganda. Cross-border e-commerce demands were 334,500, up 42.63% year-on-year and 1.47 times higher than that in 2020. The problems of negative after-sales service, failure to fulfill warranty commitments and counterfeiting of overseas products were prominent.

  (B) There are many new types of price fraud, and supervision and law enforcement are facing new challenges.

  Technologies such as big data algorithm of platform economy improve transaction efficiency, and it is also easy to induce new price fraud. The online shopping price demand was 106,700 pieces, up 99.03% year-on-year, which mainly included the problems of killing big data, changing trading conditions in real time, "marking low and closing high", concealing preferential threshold conditions, and the preferential treatment for non-members was greater than that for members, which brought higher challenges to the price supervision and law enforcement in the platform economy field.

  (C) Video membership service routines, consumer experience needs to be improved.

  At present, paid members have become the "standard" of video websites, but there is a lack of "standard" of member services, with 8534 related demands, up 103.82% year-on-year. The problems reflected by consumers mainly focus on: unreasonable advance on demand, suspected of repeated charges; The "free advertisement" is not honored, and the video is inserted with advertisements; The prompt of automatic renewal is not obvious, the way of cancellation is difficult to query, and consumers are easy to buy by mistake. Others rely on word games such as adjusting fees and changing rights to make up for losses and reduce users’ trust.

  Eight, "ODR" continued to expand, and diversified solutions to disputes steadily improved.

  Market supervision departments have vigorously promoted the construction of online consumer dispute resolution (ODR) mechanism, and the success rate of settlement and consumer satisfaction have made steady progress. 114,000 ODR enterprises have been developed in various places and settled in the national 12315 platform, and 3,094,800 disputes have been directly negotiated with consumers online. Compared with the traditional administrative mediation method, the average processing time is 7.69 days, which is greatly reduced by 14.2 days; The success rate of reconciliation increased by 11.25 percentage points; Covering 97% of cities, an increase of 2.36% over the previous year, fully releasing the institutional innovation advantages of ODR. On the whole, ODR’s social influence is constantly expanding, and the enthusiasm of market participants for voluntary participation is constantly improving, which has made a useful exploration for diversified solutions to consumer disputes and social co-governance.

  Nine, "sunshine" consumer complaint information, effectively strengthen the source of governance.

  The General Administration continued to promote the publicity of consumer complaint information, formulated a publicity system and built a publicity system, and launched pilot projects in some cities in Jilin, Guangdong, Sichuan and Xinjiang from November 2022. At present, 20,817 complaints from 14,114 enterprises have been publicized, effectively strengthening social supervision and credit constraints, and improving the transparency of the consumption environment, the integrity of operators and the satisfaction of consumers. After publicity, the success rate of complaint mediation in the pilot area increased by 8.39 percentage points compared with that before publicity and 5.97 percentage points compared with the same period of the previous year; The average complaint settlement time was 11.77 days, 2.17 days faster than the same period of the previous year; The consumer evaluation was 4.8 points (out of 5 points), 0.1 points higher than before publicity.

  X. Complaints and reports have become an important channel for discovering illegal clues, and the social supervision role of consumers continues to emerge.

  Consumers actively played the role of social supervision. In 2022, they reported 4,722,300 illegal clues to the market supervision department, up 40.34% year-on-year, including 2,027,300 illegal advertisements, 723,100 violations of consumers’ rights and interests, and 341,800 illegal food safety behaviors. Judging from the increase, reports of unfair competition, trademark violations and online trading violations all increased by more than 60% year-on-year.

  Market supervision departments adhere to the people’s livelihood orientation, strengthen the analysis and judgment of complaints and reports, and severely investigate and punish violations of laws and regulations according to law. 281,100 cases were filed for reports of illegal advertisements and false propaganda; 63,000 cases were reported and filed against violations of consumers’ rights and interests, mainly involving the sale of products that do not meet safety requirements, counterfeiting and cheating consumers; 48,700 illegal reports on food safety were filed.

Exploded, the domestic spy war is so delicious!

Domestic dramas are full of Sao operations.

It is even said that some pictures are flushed even when Uncle Ba looks at them.

Appears in the form of a full-screen mosaic.

She, the people’s female teacher.

Wearing a white gauze skirt and cutting short hair, accompanied by dim light, tutoring students and seriously teaching the appearance of ancient Chinese can be called a teacher.

The child’s Chinese score rose by 24 points.

Other departments should catch up again

You can touch the threshold of key high schools.

Teacher model?

At the end of the night, she wore heavy makeup and opened a room with the parents of the students, and she was honest with each other.

He, the taxi driver.

Listening to the guest in the car boasting that he was worth more than 100 million yuan, he kept his face unchanged, but sneaked into the other person’s home to pry open the safe, and his eyes were full of RMB gold bars.

Thieves have a lot of guts?

As soon as the camera turned, he and the other party were caught in bed by the police, and the bedside was filled with "props".

What a shameful picture, what an exciting plot.

Another drama?

No, their real identities are spies.

Opponent

The story of "spy war" in peacetime.

CCTV broadcast eight sets of prime files, and as soon as it went online, it pushed back "Knife in the Snow" for two hours.

By two words:

Word of mouth.

The main characters are Double Bombing Guarantee, Guo Jingfei and Tan Zhuo.

Even the supporting roles are Yan Bingyan and Ning Li.

But judging the quality of a drama, Uncle Ba should remain fair, objective and rational.

I didn’t dare to recommend it to you until I finished sixteen episodes in one breath.

This play-

be known asMiddle-aged poor and down-and-out version of Mr. and Mrs. Smith.

 

Modern national security spy war drama is famous for its bad.

Representative work Eye of the Storm.

Douban scored 5.6 points, and Jin Sha, the director of Lei Ju’s War of Thunder, starred in Yang Mi.

Still wearing the skin of professional drama, talking about the dog blood drama of little love.

The form and slogan are mystifying, in which the logic is ill and the plot full of slots once again enters the old road of suspension.

But "Opponent" doesn’t have these problems.

On the contrary,It broke the mystery of the spy and made every effort to be true.

First, in the choice of roles.

The spy images in spy films are often omnipotent people, who are synonymous with bullets and calm, racing and chasing, and being cold-blooded and tough.

But the truth is—

Most male spies are plain-looking, so that they are not easy to be found in society.

Li Tang, played by Guo Jingfei, pretends to be a taxi driver.

Pulling up the belly is a layer of glistening meat, and there is a serious strain on the waist muscles. A bitter face all day is the image of a middle-aged man suppressed by life.

The choice of female spies usually gives priority to face value. It is undeniable that many men have weak legs when they see beautiful women, and their appearance advantages have a better chance to get information.

Ding Meixi, played by Tan Zhuo, is a very attractive teacher.

With a charming face, every man, from parents of students to researchers, fell at her feet without exception.

And then to spy technology.

Before you become a spy, you will have a wave of training.

A few key points:Reconnaissance and anti-reconnaissance ability, first aid training, attention memory training.

But the NSA doesn’t eat for nothing.

The members of the task force are capable people, have strong endurance, and drive for 27 hours without sleeping; Those with high IQ and memory will never forget anything; If you are desperate, you can handle the case without eating or sleeping; There are hackers, especially good camouflage …

It is a compulsory course for them to remain keen and skeptical at all times.

When recruiting personnel, even the tolerance of squatting will be taken into account.

There is such an episode in the play that is quite exciting-

Ding Meixi, a female spy, was almost exposed when a student accidentally cut her hand while making up lessons at her home.

Two details:

First, emergencies, no hurry.

The student’s hand was cut by a metal tool. She immediately bandaged and stopped bleeding, and took the student to get a tetanus shot at the first time.

According to the students, Mr. Ding is more powerful than that.

Before, some students in the school fell down the stairs, and the bones were exposed. The scene was terrible. The principal was scared at that time, but Mr. Ding took his time to connect the students’ hands and helped them to the hospital.

Second, super memory, beyond ordinary people.

After handling the students’ hands, Mr. Ding received calls from other students’ parents.

Parents said that the schoolbag was left at Teacher Ding’s house. Even in such a hurry at that time, she was still very sure about the size and shape of the schoolbag, and she was sure that the schoolbag was definitely taken away from her house.

Even, she remembers the belongings of dozens of students in the class.

Although Teacher Ding explained that students’ affairs are more important, these two points still attracted the attention of parents of students and the head of the task force of the Ministry of National Security.

Not stupid confrontation, confrontation between eyes and words, uncle pai didn’t dare to blink easily when he looked at it.

But "Opponent" is about more than that.

Pull open the mysterious veil of spies, and there is another layer of hidden sorrow.

 

Spies are not so easy to be.

Li Tang and Ding Meixi are such a disguised couple.

Seventeen years ago, they accepted the task and came to Xiamen, with a unified code name of Phoenix.

In the past 17 years, they have been married and given birth to daughters like ordinary couples. For more than ten years, from sweet love to daily necessities, people are still facing a midlife crisis when they reach middle age.

But the actual spy’s life is poor and humbled.

This couple of spies is the worst in history:

Worried that the money is not enough to spend, life is tight, children can’t keep up with their physical strength when they are rebellious, and they are still under great psychological pressure …

Those so-called cool settings of wearing sunglasses and leather clothes are just the beautification of film and television works.

As a matter of fact.

None of the good things have been touched, but the troubles have come one after another.

At the beginning, they were faced with the problem of crushing them:

The chickens ran away from the joint, and they were also taken away with their wages and expenses as spies.

The already difficult life is worse.

Li Tang can only grope for clues step by step, and the first breakthrough is Yao Ji’s younger brother.

Through investigation, he determined the direction of the other party’s travel and planned to intercept it.

I thought it would be a unilateral suppression with a golden finger. As a result, I fought with each other, and I could obviously feel Li Tang’s poor physical strength.

I got a knife and three teeth were knocked out.

If it hadn’t been for the protective measures in advance, it is estimated that it would have fallen.

Old and weak, no money yet.

When the tooth fell out, I went to fill it, licking my face and asking for a discount. However, the 9000 yuan after the discount was too expensive, so I persuaded him directly.

Li Tang over the years, there is no skill, when what a big shot with deep pockets.

Usually, he is a taxi driver. He earns 400 yuan a day, and he has to pay 220 yuan to the rental company. The rest is barely enough for the daily expenses of the family.

I was given a ticket when I was on a mission, 200 at a time, and I worked for nothing for a day.

Ding Meixi has a hard time there, too.

Constantly dealing with various men to sell sex and get information, and often encounter sexual harassment.

It is rare to make up lessons to make money as a teacher, and it is also reported by parents of students.

The money is not earned, and the two people are notorious.

A man was scolded for breaking his shoes.

As a spy, she had to have sex with people, but it made her children get involved in school and get a dirty look.

One was laughed at and cuckolded.

He can only turn a blind eye when the task requires him, and the sarcasm of others can only be swallowed by himself.

But these are small things, and they face bigger problems.

The dilemma of no choice.

On the one hand, it is the task assigned by the organization, threatening you with your own life, and you can’t escape if you want to escape.

Only success, not failure.

On the one hand, it is the attention of the Ministry of National Security. Once they start to suspect, they are in a state of being caught at any time.

Strictly guard against death and wait every day.

For a spy.

Further is death, take a step back or die.

They have no way out.

 

Domestic spy war dramas used to have a fixed mode of cool drama-the focus of the crowd, and the distinction between good and evil.

After watching too much, the audience also has a stereotype.

But the best thing about "Opponent" is that it tells the real spy life.

This is not a cool play.

The key performance isThe tragic life and hopeless future of spies.

Take Li Tang Ding Meixi and his wife in the play for example.

On the one hand, fight with your life.

Before each mission, they will do a full set of protective equipment, and it is common to use knives and guns. This is the experience that they have learned after many injuries.

On the one hand, worry about daily necessities.

Every day, apart from quarreling or quarreling, for money and for life, it seems that only in this way can people vent in middle age.

"We may be the most wronged spies in history."

Ding Meixi and Li Tang go back to their rooms every day, full of complaints and complaints.

No money, no status, even can’t go home.

Even after more than ten years in a foreign land, even if they go back, they don’t know how to live. The authorities have changed several times, and they don’t know how to take the tram.

But the grievances of two people are nothing. After all, even death is not so terrible for them.

It’s like their joint is online, chicken.

I have been a spy for a longer time than Li Tang and Ding Meixi. From young to old, I began to gasp after eating a few jiaozi, and I was afraid to get married and have children, for fear that my identity would drag others down in the future.

I live worse than a watchdog, and I have been threatened to be a traitor.

After nearly twenty years of torture, death may be the relief.

The only thing that holds them back is pretending to be a daughter born to a husband and wife, and that is their responsibility.

Beating is pro-scolding and love. Although Ding Meixi scolds her daughter for being ignorant, smoking and falling in love every day, every sentence reveals love.

They are afraid of revenge by spy organizations, and they are afraid that their daughters will see their parents arrested.

The spy in the play has a touch of sadness.

Especially Ding Meixi.

From the first class of spy training, you will be insulted by rape.

Seduction, bribery and threats are the necessary abilities of female spies.

Even Ding Meixi, who is married and has children, feels the physical and mental destruction all the time. Every time she has sex with a man to get information, she will brush her teeth and go home.

She hates this kind of herself and can’t stand this kind of life, but it’s not her choice.

And this is not only in film and television dramas.

"Opponent" is the most typical of reality, and it is also experiencing the same dilemma as the real spy.

You can’t get much money, but you have to fight with your life.

Maybe there are spies around you and me.

On the surface, they are like ordinary people, but in fact they are buried in a dark corner and will never see the sun.

Uncle Ba made a bold guess-

What the drama really wants to express may be to inform spies and people who may be rebelled.

If you get lost, you will find your way back.

 

Do you want to get COVID-19 vaccine? Disease control experts tell you

At present, the vaccination work in Covid-19, Inner Mongolia has been carried out among the target population over 18 years old. On March 29th, the reporter interviewed Yan Shaohong, deputy director of the Second Institute of Tuberculosis and Prevention of the Center for Comprehensive Disease Control and Prevention of Inner Mongolia Autonomous Region, about the effective protection and adverse reactions of Covid-19 vaccine.

"Covid-19 vaccination is the most effective way to prevent and control the spread of COVID-19, which is the most economical and convenient." Yan Shaohong said that it is the duty and obligation of every citizen to vaccinate Covid-19 vaccine, and the masses should correctly understand the safety of COVID-19 vaccine and take the initiative to vaccinate.

Yan Shaohong said that almost all people have no immunity against Covid-19, and are generally susceptible to Covid-19. After the infection, some people will develop into severe illness, critical illness and even death. After vaccination, on the one hand, most people can gain immunity; On the other hand, through the orderly inoculation of COVID-19 vaccine, an immune barrier can be gradually established in the population, and the large-scale spread and epidemic of COVID-19 can be blocked.

At present, the vaccination work in Covid-19, the key population in the whole region, has come to an end, and the vaccination work for the target population over 18 years old has also started, with two doses of vaccination, with an interval of 2-4 weeks. The principle of vaccination work is still to adhere to informed, consent, voluntary and free vaccination, to coordinate the prevention and control of normalization with vaccination work, to prudently, steadily and orderly implement local territorial responsibility and industry supervision responsibility according to law, to promote vaccination work more safely, orderly and forcefully, to gradually expand the coverage of people, and to vaccinate as many people as possible to protect the health of the broad masses of the people.

"The protective efficacy of vaccines used in China has reached the relevant standards of National Medical Products Administration’s Guiding Principles for Clinical Evaluation of Preventive Vaccines in novel coronavirus (Trial), and it also meets the index requirements recommended by the World Health Organization’s Covid-19 Vaccine Target Product Characteristics. The immune persistence of inactivated vaccine in Covid-19 is still under continuous observation. The evidence suggests that the vaccine protection period can reach at least half a year. " Yan Shaohong admits that no vaccine can guarantee that the vaccinated population will have 100% protection effect. Therefore, after vaccination with Covid-19 vaccine, the protection standard cannot be lowered in daily work and life. The general public should still keep the awareness of preventing Covid-19 infection and spread, and do personal protection. Whether vaccinated or not, they should continue to wear masks indoors or in closed places where people gather, and follow the specific prevention and control measures in various places.

Regarding the adverse reactions of COVID-19 vaccine, Yan Shaohong said that the vaccine is an exotic antigen to human body. Due to the characteristics of the vaccine and individual differences, there will be some adverse reactions after vaccination, but the incidence rate is still relatively low. At present, the adverse reactions monitored mainly include local reactions and systemic reactions. After inoculation, local reactions will cause pain, some will appear redness and some will appear induration, but these local reactions do not need to be treated and will heal on their own. The general reactions are mainly headache and fatigue, and some may have low fever. (Reporter Zhang Wenqiang)

Du Qifeng talks about the classic stand shot of "Gunfire": I don’t have money to shoot like this.


There are many classic stations in Gunfire.

    Remember the classic scene of the gun battle in the shopping mall? There is also the scene of the police patrolling the street in the park, and the six-and-a-half-minute long shot at the opening &hellip; &hellip; These are some fragments that are often deconstructed by film critics in Du Qifeng’s films, but in fact, fans prefer to hear Du Dao’s own explanation.

    Recently, Du Qifeng came to Guangzhou to attend the opening ceremony of the 13-year retrospective exhibition of Chinese film media awards, and completed a forum lecture with the theme of "Du Sir’s Modern Space" together with film critic Wei Junzi and Secretary-General Yu Xiaoyi of Chinese film media awards. Du Qifeng’s also became the opening film of this retrospective. On that day’s lecture, Du Qifeng described in detail the conception of those classic pictures in his movies. But he also admitted that in fact, the stories behind these films are not as complicated as those deconstructed by film critics. For example, many people think that the actor’s position in the scene of the gun battle in the shopping mall in Gunfire is particularly particular, but in fact it was shot because of lack of money. Du Dao said with a smile: "Sometimes, we really think too much."

Why did the actors have to stand for so long in the scene of gun battle in the shopping mall in Gunfire?

    The theme of this lecture is "SIR Du’s Modern Space". As the host, Yu Xiaoyi has prepared several fragments of related themes in Du Qifeng movies to discuss. One of them is the scene of a gun battle in a shopping mall in Gunfire: when bodyguards retreat from the second floor to the first floor of the shopping mall and hide behind different pillars, a static space lasts for a long time, and the actor’s standing position in this scene is also regarded as a very classic picture of Du Qifeng movies.

    Regarding the arrangement of the actors’ positions in this scene, fans have painstakingly made all kinds of guesses, including the change of power between the offensive and defensive sides and the comparison of vertical and horizontal space, but Du Dao told the truth, "In fact, I didn’t imagine any space at all."

    Du Dao recalled that Hong Kong film was at its lowest ebb, and he had a hard time finding a boss in Taiwan Province, who was willing to give him 2.5 million Hong Kong dollars to make this film. In this context, the director’s first thing in his creation is how to save money. "If the longer you stand, the longer the film will be? With so much time, it’s still that space. So what will happen when this movie comes out? " In other words, Du Qifeng actually shot this classic picture just to save money.


The background billboard of PTU is not a sponsorship.

At the end of "PTU", there is a gun battle scene. Is the beauty billboard in the background an advertisement implantation?

    Another work that can better reflect the sense of space in Du Qifeng’s movies is PTU, in which Yu Xiaoyi gives an example of a police patrol, which is also a particularly impressive picture of Du Qifeng movies. In addition, at the end of the film, there was a gun battle under a huge billboard, which also impressed Yu Xiaoyi. The advertisement was Athena Chu lying on his side in a swimsuit and smiling at the camera. Yu Xiaoyi always suspected that this was an advertisement implanted in the film.

    However, Du Dao smiled and admitted that there was no sponsorship. "I just thought that the background behind was too messy and ugly, so I asked if there were any big posters used, and I used them to cover the scenery behind. As a result, my colleagues found this and spread it out, only to find that it was a girl. No way, I have to shoot it like this. "

Disney dominated the US domestic market in 2016, with a box office of 3 billion yuan.

Zootopia is very popular.

1905 movie networkmessage 2016 is not very good for many people, but Disney has repeatedly broken records in this year, and many films have captured the city and performed very well. As the parent company of Marvel Comics, Lucasfilm, Pixar Animation and Disney Animation, Disney has undoubtedly become one of the film giants, and has released many high-quality works in the past year, such as,,, and so on.


Although Disney suffered a little in 2015, 2016 was undoubtedly a year of great victory. Before 2016, Disney’s domestic box office in the United States reached $3 billion, which is hard to beat. The global sales reached US$ 7.6 billion, and the overseas box office reached US$ 4.6 billion, which was a great success in the local, international and global markets.

Star Wars: The Force Awakens is a hit at the box office.

Such a milestone achievement is attributed to Disney’s series of films, especially the sequels of the series. Although the film was released at the end of 2015, it has now become the third film in the highest box office list in history, and it has also benefited Disney in 2016. Rogue One: A Star Wars Story became a powerful year-end work of Disney in 2016, and now Disney is basically desperate for defeat and constantly challenging itself.


Many of Disney’s works presented in 2016 have received rave reviews, and some of them will participate in the Oscar contest, such as "Frozen in the Sea", Zootopia, etc. From the data point of view, Disney undoubtedly firmly dominates the American film market.


However, the problems in film production can not be ignored. The number of film series and sequels has increased exponentially, which has occupied the highland of film production in the past few years. From the current situation, the situation will only get worse, which is not good news for fans who like original works and experimental films. In addition, many people find that Disney’s works are becoming more and more patterned, and the quality of Disney’s new films in 2017 is worrying.


But in any case, Disney will dominate the American film market in the future commemoration. At present, the biggest challenge for Disney’s film industry is whether they are ready to shoulder the responsibility of innovation.
