How is your pure electric car experience in the cold winter?

The discount on battery life may not be the worst thing. Recently, more than a dozen Tesla owners in Canada have reported that even the air conditioner can’t be used in winter. Not only is the car frozen at a discount, but people are also frozen with a snot and tears.

Moreover, the basic things that can’t be heated in winter are heat pump air conditioners.

This is very strange. The high-efficiency and energy-saving advantages of heat pump air conditioners have not been brought into play, but they cannot be heated, which has attracted the doubts of some Canadian car owners and attracted the attention of Tesla’s R&D team. Musk said that this is a high priority for Tesla.

But even weirder, Musk said that the failure of heat pump air conditioner turned out to be a software problem, which can be completed by firmware update. Perhaps many people have never heard of it, and air conditioners still need OTA. However, after understanding the structure and working principle of Tesla heat pump air conditioner, we can find that this set of hardware can realize 12 different functions, and all the functions are controlled by software.

Therefore, the problem of Tesla heat pump air conditioning may really be a software problem.

So, how amazing is Tesla’s heat pump air conditioner? Why can’t refrigeration occur under extremely cold conditions? Can the industry solve this problem? After reading the patent of Tesla heat pump air conditioner and having a conversation with the Weiling engineer of Midea, the car found the answer to the question.

This month, countries in the northern hemisphere ushered in the coldest time since winter, and electric vehicles also entered the worst stage of the year.

Recently, Tesla owners in Canada reported that they were driving in an extremely cold environment and the heat pump air conditioner could not be used.

Twitter user @TSelvig said that when traveling that day, the temperature had dropped to-40 C. In this extremely cold weather, when he was driving Tesla Model Y, the heat pump air conditioner could not be used. After trying to restart the vehicle and call Tesla customer service, this problem still cannot be solved, and the owner is a few hours’ drive from the nearest service center, so it is impossible to drive without air conditioning.

In the end, the family switched to a fuel car.

Another Model Y owner @paateach has a richer experience. His Model Y has no warm air for two consecutive winters.

He tweeted that he lived in Saskatchewan, southern Canada, and in February last year, he encountered the situation that the heat pump air conditioner could not be used, and there was no warm air for a whole month. Later, Tesla replaced a group of super manifolds for him, and the heat pump air conditioner could be used at that time. However, by this winter, when the temperature dropped to -30℃, he once again encountered the situation that the heat pump air conditioner could not be used.

At that time, he photographed the prompt on the car screen: the cockpit climate control system needs maintenance, and the heating and cooling systems will be restricted or unusable.

Two car owners questioned Tesla: Why did Tesla’s heat pump air conditioner fail in extremely cold weather? Tesla has been repaired several times, why is the maintenance plan still invalid?

Some car owners even said that after this winter, they hope to sell their Tesla in exchange for a fuel car, at least there will be no air conditioning and heating failure.

Angie Dean, chairman of Tesla Owner’s Club in Alberta, Canada, said: "In Alberta and Saskatchewan, Canada, more than a dozen Tesla owners have experienced the problem that heat pump air conditioners cannot be used."

Just last week, the owner community Drive Tesla Canada tweeted @ Musk, asking him to comment on the heat pump problem. Musk replied to the tweet within 5 minutes, saying that maintaining the heat pump air conditioner has a very high priority. After 40 minutes, Musk said that the new firmware of heat pump air conditioner has been introduced to users.

It is quite curious that why the failure of heat pump air conditioner can be repaired by firmware update? In addition, after the firmware update is completed, there is still feedback from the owner that heating cannot be done. Is the firmware update useful?

In a patent document published by Tesla in 2019, the structure and operation mode of the heat pump air conditioning system were demonstrated. At the beginning of 2020, with the mass production of Model Y, this patent was also transformed into the mass production application of Tesla.

If you open the front case of Tesla, you can see the heat pump air conditioner and many pipes and harnesses. In fact, this is just the tip of the iceberg of the heat pump system. From the patent drawing, Tesla’s heat pump air conditioner has 11 main components, and is responsible for the thermal cycle of the whole vehicle, which can lead to different parts of the vehicle such as cockpit, battery pack and motor.

These main components are compressor, cabin condenser, cabin evaporator, battery system cooling device, cabin blower, motor liquid-cooled condenser, storage battery, three-way compressor air outlet, low-voltage electric cabin heater (PTC), recirculating air conditioner and heating.

Among the 11 main components, Tesla did not directly cancel the traditional PTC heating, but still equipped with a low-voltage PTC heating. However, due to the lack of power, this PTC heating device can not directly heat the cabin, but provides auxiliary heating when the heat pump system is insufficient.

Surprisingly, Tesla’s hardware can realize 12 different working modes, which are completed by different software scheduling.

Among these 12 working modes, there are only three modes in which heat pump participates. Heat pump participation in heating can be divided into pure heat pump mode and mixed heating mode. When the heat pump efficiency is high, the pure heat pump mode is activated, and when the efficiency is low, the mixed heating mode is activated. The heat pump can be mixed with PTC heating and can also be added to the evaporator for heating together.

In addition, the cabin and battery system can be heated simply by using the compressor and evaporator. In addition, the in-vehicle thermal circulation system can also realize the functions of cabin defogging, defrosting, dehumidification and so on.

A conclusion can be drawn here: it is indeed feasible to fix the problem of heat pump air conditioning through firmware update.

When there is nothing wrong with the hardware of the heat pump air conditioning system, the adjustment of the heat pump air conditioning system can be realized by adjusting the software scheduling in different environments.

As far as the heat pump system is concerned, there is a strong relationship between the efficiency of heating the cabin and the efficiency of the heat pump. Because the working principle of heat pump air conditioning is to exchange heat energy inside and outside the car.

Through the evaporator, the refrigerant can absorb heat from the external environment, and after the refrigerant in the car is liquefied, it releases heat, so that it can heat the cabin.

However, if the temperature of the external environment is lower, it is more difficult for the refrigerant to obtain heat from the external environment, which leads to the low heating efficiency of heat pump air conditioning in extremely cold environment.

Tesla also knows this obvious problem, so it adds auxiliary heating devices in addition to heat pump air conditioning.

Tesla drew a chart in the patent, which can explain the efficiency of heat pump air conditioning at different temperatures. The efficiency coefficient of heat pump air conditioning is expressed by COP(Coefficient of Performance). When COP=1, it means that the consumed electric energy is equal to the generated heat energy. When COP>1, the heat pump air conditioner is in the high efficiency area, which means that it can get more heat energy by consuming less electric energy.

As can be seen from Tesla’s chart, when the ambient temperature and battery temperature are lower than -20℃ at the same time, the efficiency of heat pump air conditioning will be very low, which is also considered as extremely cold temperature by Tesla, and there is no solution below this temperature. But at this time, just heat the battery, the COP value will increase, and the heating system can be used normally.

When COP=1, the heat pump air conditioner does not work and relies on evaporation to achieve heating. When COP≥1, the heat pump air conditioner will participate in heating, and the temperature needs to be above -10℃.

The second conclusion can be drawn here: if the weather outside is extremely cold, even if the firmware of the heat pump air conditioner is updated, the heating effect will still be poor. The solution is to heat the battery, or preheat it before going out.

However, under the tweet that Musk replied to the updated firmware, there are still many users who feedback that the vehicle still cannot heat.

Then, there is probably a hardware problem.

Tesla owner @paateach said on Twitter that his Tesla Model Y has been replaced with two super manifolds, including the sensor of heat pump air conditioner, expansion valve and refrigerant pipeline. The heating system can be used temporarily, but I am very worried that it may be damaged again.

Twitter user Tesla owner revealed the research and development story of heat pump air conditioner online. Recently, Tesla’s engineers in California and Alaska are testing heat pump air conditioners. The test results show that Tesla’s heat pump air conditioners can work normally below -30℃ because the heat pump air conditioners have two refrigerant cycles.

At the same time, engineers also found the problem: in extremely cold weather, the cover plate of the front air inlet will be frozen and damaged, which will lead to the inhalation of cold air during driving. Because the cold air temperature is too low, the sensor will report an error to the system after sensing it. At this time, the compressor will stop working and the heating will stop.

In order to solve this problem quickly, Tesla may start the compressor by software, temporarily avoiding the heating failure in extremely cold weather. But to solve this problem completely, Tesla may need to update some hardware later.

For the automotive industry, heat pump air conditioning is still a new thing, and Tesla Model Y was mass-produced in early 2020. Prior to this, pure electric vehicles generally used PTC to heat the interior of the car. But even under ideal conditions, the COP of PTC is 1. Low efficiency leads to very large electricity consumption for PTC heating, which further becomes a major factor affecting the battery life of electric vehicles in winter.

The efficient performance of heat pump air conditioning has attracted the attention of electric vehicle companies. In 2021, all new pure electric vehicles were basically upgraded from PTC heating to heat pump air conditioning. However, due to the limitation of refrigerant, when the temperature is below -10℃, the efficiency of heat pump will be greatly reduced. At this time, it is necessary to rely on PTC heating to heat vehicles.

For example, Tucki P5 is equipped with a heat pump air conditioner to achieve efficient heating, but it is also equipped with PTC. When the temperature is lower than -10℃, the vehicle will start PTC heating to heat the interior.

It can be said that Tucki P5 has solved the shortcomings of heat pump air conditioning to some extent, but it has not been completely solved.

Weiling, another new auto parts manufacturer, has solved the heating problem in extremely cold weather. Speaking of Weiling, maybe many friends in the automobile circle are no strangers. Weiling is a subsidiary of Midea Group, a domestic appliance head enterprise.

Last year, several auto parts announced by Weiling included automotive heat pump air conditioners.

At present, R134a(CH2FCF3, tetrafluoroethane) is usually used as the refrigerant for heat pump air conditioning, but when the outside temperature is low, the heating capacity is obviously attenuated. Therefore, there are explorations of mixed refrigerants in the industry, but the performance cannot be significantly improved.

The engineers of Weiling parts found another way, using carbon dioxide as refrigerant, and the heating efficiency was obviously improved at extremely cold temperatures.

Weiling’s rotary CO2 electric compressor can achieve a heating efficiency of COP=2 at -30℃. At the same time, the noise is low during operation and the overall design is lighter.

Engineer Weiling introduced that in extremely cold weather, users don’t need to "cover the quilt" to drive. At the same time, compared with traditional heat pump air conditioners, the heat pump with carbon dioxide as refrigerant can increase the cruising range of vehicles by up to 20%.

The CO2 electric compressor alone has 220 domestic invention patents and 14 international invention patents, and has completely independent intellectual property rights. At the same time, CO2, as a common greenhouse gas, is collected and used as a refrigerant, which also contributes to "carbon neutrality".

Last year, the heat pump air conditioning products of Midea Group Weiling components have been installed on pure electric brand vehicles such as Tucki and Weilai, which has become a microcosm of the rapid transformation of domestic component enterprises to electrification.

In 2020, Tesla put the heat pump air conditioner into a pure electric vehicle, which led the electric vehicle industry to take another step towards high efficiency. In just one year, by 2021, heat pump air conditioning has become the standard of high-end electric vehicles.

Obviously, the technology that will not be used in the era of fuel vehicles may be a huge innovation in the era of electric vehicles. In today’s increasingly fierce global competition for electric vehicles, there is still huge room for innovation in the field of electric vehicles.

　　The proliferation of gun violence has become a cliche in the United States. According to the data of the US Centers for Disease Control and Prevention, there were nearly 40,000 people who died at gunpoint in the United States in 2019, of which one-third died of murder and nearly two-thirds died of suicide. In addition, the proliferation of firearms will cause about 115,000 people to be disabled in the United States every year. In contrast, since the US military entered Afghanistan in 2001, the death toll of the US military there is 2,312.

　　According to the report of American Broadcasting Corporation (ABC), the annual economic loss caused by gun injuries in the United States is about $300 billion, and the GDP of the United States is nearly $21 trillion in 2020. That is to say, the annual economic loss caused by guns is equivalent to 1.3% to 1.5% of the GDP of the United States. Putting this proportion into the huge economic aggregate of the United States, the absolute value is still very amazing: it is equivalent to Americans destroying a Finnish economy every year because of shooting (Finland’s GDP will be 300 billion US dollars in 2020).

　　It can be said that the severity of gun violence in the United States is unique among developed countries. Therefore, the issue of gun control has become a jargon in the debate of the American Congress. However, despite the fierce quarrels among lawmakers, they often start this endless debate whenever there is a large-scale shooting incident. However, in the past 50 years, there has been no real substantive decision on gun control and solving the problem of gun proliferation.

　　So, what makes it so difficult for the United States to control guns?

　　The reason why Americans have the right to hold guns is a bit roundabout.

　　First of all, we must clarify a concept, that is, the argument that people are free to hold guns in the Second Amendment of the US Constitution, which is emphasized by many gun-holding organizations, looks more like an absurd historical "myth" today.

　　In 1791, the US Congress passed the Second Amendment, saying that "a well-disciplined militia is necessary for the security of a free country; The people’s right to hold and carry weapons shall not be violated. " The reason for enacting this amendment is that holding guns by citizens will help prevent the expansion of the power of the federal government and prevent the government from imposing tyranny on the people.

　　It is true that many armed militiamen joined the struggle against British "tyranny" when the North American colonies became independent, but these militiamen with no military organization and no logistical support could not resist the attack of the British regular army for a long time. Even many militiamen joined the war of independence with the mentality of firing a few shots and sneaking home to continue farming if they failed.

　　The American War of Independence can be won, thanks to the French navy’s unprecedented defeat of the British Royal Navy, which has always been invincible in the 18th century. As a result, the British main force entrenched in Yorktown was cut off, and the commander-in-chief cornwallis was forced to surrender to the French army and the Continental Army led by Washington. The powerful "armed militia" is the "founding myth" of the United States, and it is the regular navy and army that really overturns the British.

　　△ In the Chesapeake Bay naval battle, the French fleet successfully prevented the Royal Navy from rushing to help the British main force stationed in Yorktown, thus controlling the sea power in the theater, causing the British army to declare its surrender after running out of ammunition, thus ending the American War of Independence.

　　Moreover, individuals with guns can never compete with the state machine, and the US federal government does not hesitate to use military power far beyond the firepower of the people’s guns to carry out armed repression. During the American Civil War, a large-scale anti-conscription riot broke out in new york, and the American government responded with artillery. Some even said that warships moored in new york also participated in the suppression of the rioters. Unlike the revolvers commonly used by rioters at that time, the heavy weapons of the army were not available to the people at all, and even if they were held, they could not afford to maintain them.

△ In 1863, there was a conscription riot in New York, and the army used artillery to suppress the participants in the riot. (Source: new york Times)

　　In the 21st century, with the rapid progress of military science and technology, the firepower gap between the army and the people holding guns is even greater. Not only that, since the Bush era, the US military has also transferred surplus military equipment to local police through the so-called "Project 1033", and the US special forces have trained police officers, which has made the American police a veritable paramilitary organization. Under such circumstances, the American people also know that there is no good end to engaging in large-scale armed riots. Therefore, when the new york police made a move, the crowd dispersed.

　　After this year’s farce of "Occupy Capitol Hill", no one has stood up with guns and opposed the US government’s nationwide night fall.

　　The biggest beneficiary of people holding guns is the southern slave owners.

　　In fact, I’m afraid that the reason why the Second Amendment to the US Constitution was passed that year was not that members of Congress really believed that people holding guns was conducive to resisting the government’s "tyranny".

　　At that time, it was not long after the Shays Uprising (1786-1787) against the Massachusetts authorities, and the argument that people could not be trusted was still popular among the political elites in the United States at that time. In fact, the biggest beneficiary of allowing people to hold guns is the slave owners in the south.

　　When the United States was founded, slave farming was the most obvious private industry that relied on guns. In order to prevent slaves from rioting and fleeing, unofficial "slave patrol" system appeared in southern States, which is also one of the origins of American police system. According to the logic of slave owners, these slave patrols are also "well-disciplined militia" mentioned in the Second Amendment to the Constitution. The existence of slavery also explains why the amendment emphasizes that "well-disciplined militia" is crucial to national security, because only whites could join the militia at that time. Emphasizing that "militia" owns guns, not individuals, can exclude blacks from the ranks of gun owners and realize the absolute superiority of whites over blacks in force. At that time, the slave uprising in the French colony of Haiti was in full swing, and black slaves slaughtered a large number of white slave owners, which seriously stimulated American slave owners.

　　It can be said that it is an inevitable interest proposition of these people to emphasize the gun support right of white militia.

　　The Paradox between Gun Control and Law

　　At this point, we can see that the Second Amendment to the American Constitution is out of touch with the development of the times, and the basis of legislation at that time seems to be contrary to the basic moral standards of mankind today. This amendment is also the most fundamental legal reason for the inability to control guns in the United States today.

　　However, as a basic law, the American Constitution can hardly be amended again. According to the current law, amending the Constitution requires at least two-thirds of the members of the Senate and the House of Representatives, respectively. However, in the Congress where politics and lobbying prevailed in Jin and Yuan Dynasties, lobbying organizations, represented by the National Rifle Association of the United States and reflecting the interests of various arms dealers, have long held key members firmly in their own hands. Not to mention amending the constitution, any attempt to tighten gun control at the state and federal levels will be strongly and effectively stopped by the Rifle Association.

△ The National Rifle Association (NRA) is one of the most important political lobbying groups in the United States. (Source: NRA official website)

　　Not only Congress, but also the judiciary has played a very disgraceful role in the problem of gun proliferation in the United States.

　　Compared with long-barreled firearms, pistols are more secretive, which is beneficial for gunmen to engage in large-scale shooting by surprise, and is also very suitable for suicide. Therefore, the city government of Washington, the capital of the United States, once attempted to completely ban the possession of pistols. However, in 2008, the United States Supreme Court ruled that the actions of the Washington municipal government were unconstitutional, and at the same time reinterpreted the Second Amendment, confirming that the right to own guns was not limited to militia, but included all individuals. Since the ruling of the Federal Supreme Court is final, it means that gun control efforts in many states have been wasted.

　　The game of gun control and gun prohibition

　　Of course, the justices of the Federal Supreme Court did not forget to show their "neutrality" in their judgments, claiming that guns and gun rights still need to be managed by someone. Nice words, but how to "manage" guns is a mess that puzzles American politicians.

　　Due to the federal nature of the United States, the responsibility for formulating specific gun management policies is shared by the federal government and local governments. The federal government is responsible for issuing gun sales licenses and conducting background checks on gun buyers to confirm that they have no criminal record before they can legally hold guns. Local governments are responsible for formulating specific provisions for carrying guns in public places. It seems that governments at all levels have a clear division of labor, but there are many loopholes in actual operation.

　　First of all, not everyone needs a federal license to sell guns. If they are selling guns in their own homes, online or at gun exhibitions, they do not need a federal license to sell guns for long-term profit. Because enterprises and individuals with sales licenses have the responsibility to inform the federal government of the identity of gun buyers so that they can conduct background checks, this means that when sellers without licenses sell guns, the federal government cannot investigate the identity of buyers. According to a study conducted by Harvard University in 2017, one-fifth of the gun transactions in the United States have not undergone background checks.

　　Second, since gun ownership has become a "natural human right", only a few states require residents to apply for a gun license. Therefore, most of the time, the government passively screens the legitimate owners when the gun trade takes place. Except for those States that need to have a license to buy guns, local governments can’t actively screen gun owners or train gun owners in the code of conduct.

　　Third, even if a comprehensive background check system is implemented nationwide, as many gun control groups now support, to plug the loopholes that guns can’t be investigated during gun exhibitions or online purchases, or to implement a nationwide gun purchase license system, it can’t solve a core problem, that is, because guns in the United States have been flooding for a long time, a large number of criminals illegally buy guns through the black market instead of through formal channels. This means that no matter how many gun control policies are formulated by the government, as long as the United States can’t implement a strict national ban on guns, people who want to own guns always have ways to deal with it. All gun control policies instead of banning guns are aimed at preventing gentlemen and not villains.

　　Why is there no solution to the rampant gun violence?

　　The problem of gun proliferation in the United States is a typical institutional case. The revision of the Constitution, the legislation of Congress, the interpretation of the law by the courts, the separation of powers between the central and local governments, lobbying and the intervention of interest organizations, almost all kinds of gloomy aspects in American politics are reflected in the gun issue. To solve the problem of gun violence in the United States, I’m afraid what we need is not to tinker with a certain law, but to thoroughly reform the system of representative federalism with three powers, which is full of ills. But this is completely impossible to achieve in the United States today, so we can only let it go.

　　Now, Americans are completely numb to large-scale gun incidents. Since the beginning of this year, there have been nearly 250 large-scale shooting incidents that have caused more than three casualties. Gun control, like other stubborn diseases that cannot be solved because of the American system, has become a tool used by politicians to attack each other. The more quarrelling, the less means to solve it properly, and the gun violence will continue. After all, members of parliament live in wealthy areas with good public security, and the shooting of people is still far away from them. (Contributed by Jing Zhao)

Bulletin of Heilongjiang Provincial Department of Education on 29 Typical Cases of Teachers Violating Teachers’ Morality and Morality

　　CCTV News:In this year’s government work report, the cancellation of provincial toll stations on national expressways was mentioned again. Today, the Ministry of Transport introduced the latest progress of this work.

　　According to the statistics of the Ministry of Transport, there are still 229 toll stations on the main expressway in China. The cancellation of these toll stations involves the reform and innovation of the toll collection mode, as well as a large number of hardware engineering construction and software upgrading, the unification of relevant policies, and the placement of personnel, which is quite difficult.

　　Wu Chungeng, spokesperson of the Ministry of Transport: Because expressways are built and operated by provinces, involving many business entities and some economic organizations, they all entered according to the law, and now they have to withdraw their stations, which involves fund settlement. In order to reflect fairness, the amount of coordination is very large. When it comes to personnel placement, there are about 30,000 people in more than 200 main line stations, which need to be properly placed within a certain period of time.

　　Wu Chungeng revealed that the Ministry of Transport regards the cancellation of provincial toll stations on expressways as the top priority in 2019. A special work headquarters has been set up to clarify the implementation route and related technical solutions.

　　At present, in view of each technical difficulty and risk point, the special work headquarters has formulated a plan and has specific countermeasures to achieve the goal of withdrawing the station.

　　Wu Chungeng, spokesperson of the Ministry of Transport: We will mobilize all forces and do everything possible to ensure that the provincial toll stations of national expressways will be basically cancelled ahead of schedule within two years.

　　Ten years ago, on the evening of May 1, 2011, then US President Barack Obama officially announced that bin Laden had been killed by the US military. That night, the whole nation was boiling. American public opinion believes that since the moment a Boeing 767 plane hit the North Tower of the World Trade Center in New York at 8: 46 am on September 11th, 2001, Americans have made a great progress in the war on terrorism that lasted for nearly 10 years.

　　△ On the evening of May 1, 2011, then US President Barack Obama announced at the White House that Al Qaeda leader Osama bin Laden had been killed by the US military.

　　Ten years have passed since bin Laden was killed, and various versions of the account of bin Laden’s death have appeared. From the non-fiction works of the New Yorker in paper media to Hunting Bin Laden in Hollywood, the official heroic narrative of the United States is all evident. However, with the advancement of investigation and textual research by all parties, it seems that the death of bin Laden is not as stated in the official discourse of the US government. The New York Times mentioned it together with the "Bay of Pigs Incident" and "Iraqi Weapons of Mass Destruction" and became a secret kept secret by the US government. ……

　　July 7, 2005 London "July 7" bombing.

　　Compared with the official narrative of the United States, Hollywood seems to prefer to link the death of bin Laden with international counter-terrorism. The London bombing on July 7, 2005 has also become a symbol of Al Qaeda’s infiltration into Europe and its terrorist activities in Europe.

　　△ On July 7, 2005, a terrorist bomb attack occurred in London, England. In the morning, three subways and a bus in London were detonated by bombs carried by terrorists.

　　On July 7, 2005, around 8:49 am, it was the morning rush hour in London. On this Tuesday morning, as usual, Jeff Porter was running an early train in London’s subway cab painted with iconic red and blue paint.

　　"When I was drawing in at Edgewell Road Station," Jeff Porter said, "there was a train coming from the opposite direction. Just as the other side met my front, I saw a dazzling yellow light from the other end of the oncoming train."

　　Then, the cab glass in front of Jeff broke, and dust and smoke scattered. Only then did Jeff realize that the train had exploded.

　　△ On July 7, 2005, Al Qaeda carried out terrorist bomb attacks on several traffic lines in London.

　　On the ground that day, there was an explosion against the bus at the same time. At almost the same time, four terrorists detonated bombs in four different bus facilities in London. According to the statistics of British police, the explosion killed 52 people and injured more than 700 people.

　　△ Video of Al-Qaida Statement released by Al Jazeera in September 2005

　　Two months after the terrorist attack in London on July 7, Al Jazeera broadcast a video, which confirmed the identities of the four terrorists — — A member of Al Qaeda. This video has been reviewed by the British police and intelligence agencies, and the identity and criminal process of the four terrorists have been clarified. In the tape, a terrorist declaration that mentioned "bin Laden" also touched the hearts of Americans on the other side of the Atlantic.

　　In June 2009, the "old plan" of the new president in Washington

　　Since the "9.11 terrorist attacks", then-US President George W. Bush has promoted anti-terrorism as his ruling focus. In addition to waging wars in Afghanistan and Iraq, intelligence organizations in the United States, Britain, Israel and other countries have further strengthened information sharing in international counter-terrorism intelligence because of "9.11".

　　△ "The Record of Killing Bin Laden" published by The New Yorker on August 1, 2011 — — The Night in Abbottabad describes the details of the US military’s action to kill bin Laden, but many of the details are quite different from the arguments of all parties.

　　Time came in June 2009, and four months after Obama took office as president, Leon Panetta, then director of the CIA, introduced to Obama the action plan to track down the leader of Al Qaeda since George W. Bush took office. According to The New Yorker’s Record of Killing Bin Laden — — A Night in Abbottabad, Leon Panetta knew at that time that the new president would definitely support his plan.

　　△ In October 2008, US presidential candidates barack obama and John Romney held a presidential campaign debate at Belmont University in Nashville.

　　Because one month before the 2008 US presidential election, when Obama, then a senator from Illinois, was debating with John McCain, also a presidential candidate, at Belmont University in Nashville, he answered the question about whether to hunt down bin Laden:

　　"If we see bin Laden and the Pakistani government is unable or unwilling to kill him, then we must take action. We will kill bin Laden and smash ‘ Base ’ Organization. "

　　Sure enough, as a supplement to Leon Panetta’s plan to search for bin Laden, Obama stepped up the use of drones for investigation.

　　△ According to the statistics of the Bureau of Investigative Journalism, a third-party news investigation agency, from 2010 to 2020, the drone bombing launched by the United States has caused about 8,858 to 16,901 deaths, including about 910 to 220 civilians and about 283 to 454 children.

　　In addition to inheriting the search for bin Laden by former President George W. Bush, the Guantanamo prison, which was used to hold terrorists during the Bush era, also played a key role in the future killing of bin Laden.

　　Message from Guantanamo prison in August 2010

　　Guantanamo prison, located in Guantanamo Bay, Cuba. Before 2002, the prison was basically used to accommodate Cuban and Haitian refugees who tried to sneak into the United States by sea. After the "September 11" incident in 2001, it was changed to a prison for accepting and interrogating terrorists. Restricted by the US Constitution, it is impossible to torture suspects in the United States.

　　△ The movie "Hunting Bin Laden" restored the scene in which the CIA waterboarded the detainees.

　　At Guantanamo Bay, because the US considers terrorists to be "illegal combatants", they do not enjoy any rights stipulated in the Geneva Convention, and American personnel can interrogate detainees in various ways. Since the opening of Guantanamo prison, various reports about torture by American intelligence personnel have been flowing out.

　　△ CIA documents show that the United States has secret interrogation and detention centers in many countries around the world. A secret document of the CIA shows that there is a detention center code-named "Black Field".

　　According to the documents from the CIA, in addition to Guantanamo prison, the United States has set up secret interrogation and detention centers in many countries and regions around the world for anti-terrorism operations. One of the secret interrogation bases, known as the "black field", first leaked news about bin Laden’s messenger in 2002.

　　△ The Week quoted Jose Rodriguez, the chief operating officer of CIA, as saying that the messenger of bin Laden was a Kuwaiti.

　　Abu Ahmed Kuwait — — Bin Laden’s Messenger — — The name that the CIA has been searching for has been confirmed in Guantanamo and the interrogation base set up by the CIA in Pakistan. Until August 2010, Leon Panetta, then director of the CIA, personally confirmed the whereabouts of the messenger in Peshawar, Pakistan.

　　In May 2011, the cement compound in Abbottabad

　　Through the information obtained in various interrogation bases before, the US intelligence department has strengthened the monitoring of the cell phone signal of bin Laden’s messenger. In August 2010, the CIA tracked a white SUV from Peshawar, Pakistan to Abbottabad, north of the capital Islamabad. In the detailed account, a white rhinoceros is painted on the spare tire cover hanging from the rear of the SUV.

　　△ Structural Diagram of Cement Compound in Abbottabad, Pakistan

　　According to documents disclosed by the CIA, the SUV stopped outside a compound with a three-story building with a concrete fence and barbed wire about 5.5 meters high. There is no telephone or internet connection in this compound. The observation report of the CIA for several days shows that the residents of this compound don’t even throw garbage, but burn it centrally in the hospital. Through outdoor drying clothes, the CIA judged that there were three households in the building, but only two of them went in and out of the compound every day.

　　At the end of October, 2010, then US President Barack Obama, based on the investigation report submitted by then CIA Director Leon Panetta, made him start to cooperate with all parties to design a military action plan for the compound. From the end of October 2010, the action plan was designed and officially implemented on May 1, 2011. In half a year, in order to ensure the smooth operation of killing bin Laden, the US military rebuilt a concrete wall compound for training in the forest of North Carolina. However, the action report disclosed by the United States shows that there was a huge flaw in the initial helicopter carrying the US airborne compound.

　　△ Schematic diagram of the American Black Hawk helicopter that nearly crashed when the tail of the helicopter hit the concrete wall during the operation.

　　At about 4: 00 am local time on May 1, 2011, the first Black Hawk helicopter that was supposed to hover in the compound and be delivered to the US military by ropes, just arrived at the compound, and the rotor at the tail scraped the concrete wall. In order to prevent the helicopter from rolling over, the pilot inserted the nose straight into the ground and landed in the compound in a near-crash way. After witnessing this situation, the pilot of another helicopter immediately gave up the plan of hovering on the roof and landed outside the courtyard wall.

　　△ Satellite image of cement compound in Abbottabad, Pakistan

　　The accident that the Black Hawk helicopter fell to the ground disturbed the people around it, making the planned surprise attack meaningless. In the end, according to the report of the US military, this military operation successfully killed bin Laden. The body was wrapped in a white shroud, put into a bag and finally thrown into the sea.

　　2015 US Media Survey: Another "Saving Private Lynch"

　　As for the actions of the US military in the building, the US side has various versions. One of the most dramatic is that the US military said that bin Laden pushed his wife in front of him as a human shield. Another version is that after discovering bin Laden, the US military was resisted by bin Laden, and finally bin Laden was killed in the crossfire.

　　△ The New York Times published an investigation and analysis report on the mystery of bin Laden’s death in October 2015, "Do we really know the death of bin Laden? 》

　　However, after these news quickly spread around the world, the White House and the military corrected their statements one after another. On the evening of May 2, 2011, Jay Carney, the then White House spokesman, made an erratum to the details of the previous action of hunting bin Laden. First, he said that he did not carry weapons when he died, and then clarified that he did not use his wife as a human shield. The White House said that the difference from the details released the day before was due to "too much information and too hasty preparation".

　　In the analysis and investigation conducted by The New York Times and the London Review of Books in 2015, there were discrepancies in the details of bin Laden’s death, from the very beginning when various sources obtained the information of the so-called "bin Laden Messenger" to the final burial of bin Laden’s body at sea.

　　△ On May 21, 2015, the London Review of Books published a survey of bin Laden’s death by Seymour M. Hersh, a well-known investigative journalist, and pointed out that there were a lot of flaws in the explanation of relevant events by the US government.

　　The United States carried out a massive military operation in the form of almost crashing a helicopter. The news disclosed by the media showed that bin Laden had a fierce resistance, but the official information was inconsistent, and it was difficult to confirm what actions bin Laden took in the final stage. It was obvious that there was a chance to capture bin Laden alive, but the US military directly killed him. The White House and the military’s contradictory statements on the details of the operation and the final handling of bin Laden’s body at sea ….. all these make the death of bin Laden foggy.

　　△ According to The New York Times’s report on May 4th, 2011, Obama’s personal support rate rose from 46% last month to 57% after then US President Barack Obama announced the successful killing of bin Laden.

　　But no matter which version, the American troops in the story are portrayed as a group of dead men who have gone and never returned. Such narrative methods and routines make people familiar with the history of American journalism inevitably not think of Lynch, the "heroine" deliberately created by the American government during the Iraq war.

　　△ jessica lynch, an American female soldier, was ambushed and captured while serving in Iraq in March 2003. The American government deliberately portrayed Lynch’s story as a "fighting hero who refused to surrender". After investigation by many American media, it was found that all the stories about jessica lynch were untrue stories made up by the US military.

　　The 20-year trauma of Afghanistan War in 2021

　　On May 1, 2011, then US President Barack Obama announced that it has been 10 years since the United States successfully killed Al Qaeda leader Osama bin Laden. According to a statistic from Brown University, as of mid-April this year, at least 47,245 Afghan civilians have been killed in the war since 2001. The war also killed 66,000 to 69,000 Afghan soldiers.

　　△ Washington post reported on April 30, 2021 that former US President Barack Obama explained the significance of the hunt for bin Laden.

　　Ten years later, in 2021, Obama, who had left the presidency, appeared again to explain the significance of the action of hunting bin Laden.

　　Unlike 10 years ago, Obama no longer needs to face the test of a second term. In the face of his decision to continue the war in Afghanistan and kill bin Laden when he was in power ten years ago, Obama seems to remember those American soldiers who died in Afghanistan. However, the fact is that the war in Afghanistan since 2001 has caused 2,442 American soldiers to be killed, 20,666 injured and more than 3,800 American security contractors killed.

　　When the United States continues to face downward economic pressure and domestic public opinion is increasingly opposed to the wars in Afghanistan and Iraq, both former President Trump and current President Biden threatened to let the US troops leave Afghanistan in the 2020 general election. It was not until April 29th this year that the White House confirmed that American troops had begun to leave Afghanistan, and the war in Afghanistan, which lasted from 2001 to the present, came to an end with American troops leaving Afghanistan.

　　However, Obama seems to have forgotten that on January 22, 2009, the third day after he took over as president, Guantanamo prison, which had requested to be closed as soon as possible, still holds more than 40 people.

　　　　　　 CCTV News:Today (March 22nd) is the 31st World Water Day, and the United Nations has determined that the theme of World Water Day in 2023 is "accelerating change". From March 22nd to 28th, the 36th China Water Week was held, with the theme of "Strengthening water control according to law and working together to protect the mother river".

　　　　　　 Water is the source of all things and the foundation of all things. First of all, let’s learn about the familiar "water" in our daily life through a word. Now displayed on the big screen is the earliest word "water" in China. It appeared in Oracle Bone Inscriptions in Shang Dynasty, and it looks like water flowing along water veins, but its original meaning is river.

　　　　　　 Early human civilization originated from both sides of the river, and our mother river, the Yellow River, gave birth to an uninterrupted Chinese civilization for more than 5,000 years. "The Yellow River is peaceful and the world is peaceful". How to better protect the mother river has become an important topic in modern water conservancy construction.

Legislation to protect the mother river, the ancient Yellow River, rejuvenated.

The Yellow River is the mother river of the Chinese nation, and its protection is a great plan for the great rejuvenation of the Chinese nation. On April 1st, the Yellow River Protection Law will be implemented soon, and there will be laws to protect the Yellow River.

In Shandong Yellow River Delta National Nature Reserve, the oriental stork, a national first-class protected bird, entered the breeding period. After a long incubation period, recently, the first chick hatched this year.

Thanks to the start of the Yellow River ecological water supply and wetland restoration project, the Yellow River Delta National Nature Reserve has become the most important breeding ground for oriental storks in the world, and millions of birds migrate and winter here every year. It has also become the most complete, extensive and youngest wetland ecosystem in the warm temperate zone of China.

In the Yellow River Protection Law, which will be implemented on April 1, specific measures such as ecological water replenishment and silt dam construction in the Yellow River Delta have been written into the legal provisions.

Gui Fan, Deputy Director of Policy and Regulation Bureau of Yellow River Conservancy Commission:The Yellow River Protection Law is a summary of many years’ experience in harnessing the Yellow River, which has raised an effective experience in harnessing water and sediment loss in the Yellow River basin to a legal level, which was not found in any previous law.

The Law on the Protection of the Yellow River clearly states that the state strengthens the ecological protection and restoration of the Yellow River basin, adheres to integrated protection and restoration, and implements systematic management with natural restoration as the mainstay and natural restoration combined with artificial restoration. The state implements a rigid restraint system for water resources in the Yellow River Basin, and insists on setting cities, land, people and production by water.

　　　　　　 Li Xiaojing, Deputy Director of Policy and Regulation Department of Ministry of Water Resources:On the basis of fully performing their statutory duties, the nine provinces and regions in the Yellow River Basin should focus on the key points in combination with the actual situation. The upstream provinces should strengthen the protection and restoration of water conservation areas, the middle provinces should strengthen the soil and water conservation on the Loess Plateau, and the downstream provinces should strengthen the economical and intensive use of water resources, jointly do a good job in great protection and promote great governance, and create a new situation of ecological protection and high-quality development in the Yellow River Basin.

This year, China will further promote the recovery of the Mother River.

Just now, we saw that the measures for the protection and management of the Yellow River are constantly being iteratively updated. In addition, this year, China will further promote the recovery of the mother river, make the river flow, restore the lake, and build a harmonious symbiotic system of people and water.

Bi Shouhai, Director of Water Resources Protection Division, Water Resources Management Department, Ministry of Water Resources:This year, the Ministry of Water Resources will select 88 mother rivers (lakes), formulate the mother river recovery action, "one river, one policy" and "one lake, one policy" programs, strengthen the unified regulation of water resources, promote river regulation, water system connection, ecological water replenishment, groundwater overexploitation control, and gradually return the occupied ecological water, so as to restore the life of rivers and the vitality of basins.

At the same time, this year, the state will focus on the Beijing-Hangzhou Grand Canal and rivers and lakes in North China to continue to promote centralized and normalized water replenishment, so as to realize the 707-kilometer-long connection of the Beijing-Hangzhou Grand Canal to the north of the Yellow River, and the water surface area of Baiyangdian Lake will be stable at more than 250 square kilometers throughout the year.

Recently, the Ministry of Water Resources has formulated and issued the "Key Points of River and Lake Management in 2023", which will comprehensively start the health evaluation of rivers and lakes and gradually establish a national river and lake health archive; Strictly control the shoreline space and sand mining management in rivers and lakes, and further promote the normalization and standardization of the "four chaos" in rivers and lakes.

Li Xiaojing, Deputy Director of Policy and Regulation Department of Ministry of Water Resources:(River and lake management) Pay more attention to the basin as a unit, strengthen the unified planning, unified management, unified dispatching and unified management of the basin, and plan the overall situation of basin protection and management as a whole.

China government assists Malaysian anti-epidemic materials to arrive at Kuala Lumpur International Airport. Xinhua news agency

　　General Secretary of the Supreme Leader pointed out at the G-20 leaders’ special summit on COVID-19 that major infectious diseases are the enemies of all mankind. The COVID-19 epidemic is spreading all over the world, which poses a great threat to people’s life safety and health, and poses a great challenge to global public health safety. The situation is worrying. At present, what the international community needs most is firm confidence, Qi Xin’s concerted efforts, United response, all-round strengthening of international cooperation, cohesion of a strong joint force to overcome the epidemic, and joint efforts to win this human struggle against major infectious diseases. In the face of the epidemic, as a community of destiny in which you have me and I have you, all countries in the world should act quickly, unite the strong synergy of unity, cooperation and common response, and protect the health and peace of the common home of mankind.

　　1, gather together to fight the epidemic.

　　At the critical moment when the global situation of COVID-19 epidemic prevention and control is becoming more and more severe, the G20 leaders’ first special summit meeting in response to COVID-19 by video released a positive signal of joint prevention and control by the international community, and opened the world agenda of building a prevention and control cooperation mechanism, which indicates that the global joint efforts to fight the epidemic will move from value consensus to pragmatic operation.

　　Global joint efforts to fight the epidemic is an inevitable choice to effectively curb the spread of the epidemic. At present, the COVID-19 epidemic is spreading rapidly around the world. According to the World Health Organization, the COVID-19 pandemic has not been effectively contained, and it is growing at an exponential rate. If the international community fails to take joint measures, millions of people may be killed. At the same time, affected by the COVID-19 pandemic, the risk of world economic recession is increasing, the international financial market is in turmoil, the unemployment rate in some countries is rising rapidly, social panic is spreading, and populism and trade protectionism are on the rise. A series of secondary disasters caused by the epidemic are causing more and more concern and anxiety. No country can stay out of it and be immune to it.

　　Global efforts to fight the epidemic urgently need the concerted efforts of the international community. The outbreak and spread of COVID-19 epidemic in the global scope are different in time, region and degree. This determines that countries must strengthen policy coordination, joint prevention and control, and strengthen communication and sharing of relevant information. On the one hand, the international community should strengthen information sharing, carry out cooperation in drug and vaccine research and development and epidemic prevention, effectively prevent the cross-border spread of the epidemic, and especially work together to help developing countries with weak public health systems improve their coping capacity. On the other hand, with the rapid spread of the epidemic, the demand of countries for medical and health protection and other related materials has surged sharply, which requires the global industrial chain, especially the hub countries, to deepen capacity cooperation, dig deep into capacity potential and achieve the most efficient supply. At the same time, in view of the serious impact of the epidemic on the world economy, countries should also strengthen the adjustment and docking of macroeconomic policies to ensure the openness and stability of the global market and boost the confidence of the world economy.

　　2, joint efforts to fight the epidemic need to build consensus.

　　The outbreak of the COVID-19 epidemic shows once again that human beings are a community of shared destiny. How to effectively curb the spread of the epidemic and prevent and resolve the secondary disasters of the epidemic is a major issue related to the interests of all countries and the future and destiny of mankind. At a critical juncture, is Qi Xin working together to protect the homeland, or is it selfish, narrow-minded and malicious? Is it to join hands to fight the epidemic and overcome the difficulties together, or to create rumors and stigma? It not only tests the governance ability and responsibility of all countries, but also tests the collective rationality and moral spirit of mankind.

　　Common challenges need to be met together. Epidemic diseases, regardless of national boundaries and races, are the common enemies of mankind. With the rapid flow of people, goods and information, epidemic diseases can easily break through the time and space boundaries and national boundaries, quickly spread from one country to many countries, and detonate the global public health crisis. What’s more, compared with many diseases, COVID-19 virus has stronger infectivity and higher pathogenicity, which can spread to all parts of the world through individual personnel flow, resulting in a huge global and random risk, and the prevention and control is more difficult than ever. Only by working together can we win the battle. All countries in the world should actively carry out international joint prevention and control from the height of building a community of human destiny to jointly safeguard global public health security and human health and well-being.

　　Common goals require unity and cooperation. Building a world of lasting peace, universal security, common prosperity, openness, tolerance, beauty and cleanliness is the common goal and beautiful pursuit of people of all countries, and it is also the rich connotation inherent in building a community of human destiny. The sudden epidemic not only directly threatens the global public health security, but also profoundly affects the economic and social development and prosperity of all countries. As a result, the fight against the COVID-19 epidemic has gone beyond the field of public health and evolved into an overall war and a blocking war to safeguard the prosperity and development of the world and protect human civilization. The international community must establish an effective cooperation mechanism and strengthen communication and coordination in personnel management, scientific research, experience sharing and material production, so as to cope with the crisis and win victory through cooperation.

　　The common destiny needs to be in the same boat. There is only one earth for mankind, and all countries coexist in one world. The earth is the common home of mankind and the only home of mankind so far. The objective living conditions and the era environment of "you have me and I have you" make the future and destiny of every nation and country closely linked, with one glory and one loss. As General Secretary of the Supreme Leader emphasized, the occurrence of the COVID-19 epidemic once again shows that mankind is a community of shared destiny. In the era of economic globalization, such a major emergency may not be the last time, and various traditional and non-traditional security issues will continue to bring new challenges. The international community must establish a sense of community of human destiny, help each other, work together to meet the risk challenges and build a better home on earth.

　　3. Make China contribution to joint efforts to fight the epidemic.

　　China is an advocate of the concept of community of human destiny, and also the most powerful promoter and practitioner of this concept. General Secretary of the Supreme Leader stressed, "I advocate co-construction ‘ Belt and Road ’ And building a community of human destiny is to promote exchanges and mutual learning among different civilizations and mutually beneficial cooperation among countries, and to build a world of lasting peace, universal security, common prosperity, openness, tolerance, cleanliness and beauty. " In this war without smoke, China has been actively supporting the international community’s anti-epidemic efforts with practical actions, and has provided assistance to international organizations including the World Health Organization and more than 80 countries. This is a vivid practice of the concept of a community of human destiny. The speed of China has won precious time for world epidemic prevention, China has built the first line of defense to control the spread of global epidemic, and the practice of China has set a benchmark for human beings to deal with major public health emergencies. The strategic deployment and policy measures adopted by China in the process of epidemic prevention and control, as well as the universally recognized achievements, have greatly demonstrated the urgency and necessity of building a community of human destiny and contributed valuable spiritual wealth to the global joint efforts to fight the epidemic.

　　Maintain the heroic spirit of facing difficulties. Difficulties inspire fighting spirit and challenge the spirit. The Chinese nation has experienced many hardships in its history, and has never been crushed. Instead, it has become more frustrated and brave. It is because we always have the belief of winning in the face of any difficulties and obstacles, and dare to struggle and win. The more difficult and dangerous, the more forward we are. After the outbreak of the epidemic, the CPC Central Committee with the Supreme Leader as the core United and led the people, braved difficulties and faced difficulties, put forward the general requirements of firm confidence, helping each other in the same boat, scientific prevention and control, and precise policy in time, made clear the overall goal of resolutely curbing the spread of the epidemic and resolutely winning the prevention and control of the epidemic, and quickly launched the people’s war, the overall war and the prevention and control of the epidemic. In the face of the complicated and severe global anti-epidemic situation, all countries in the world should launch a "life-and-death struggle" with the new crown pneumonia virus with heroic spirit to fight hard and fight to the end.

　　Adhere to the concept of win-win cooperation. Peace, development, cooperation and win-win are the trend of the times, and they are also the basic principles that must be observed in the fight against the COVID-19 epidemic. During the epidemic period, China, in an open and transparent manner, informed the World Health Organization at the first time, shared information with other relevant countries at the first time, and shared the whole gene sequence of the virus to the whole world at the first time, and actively carried out all-round cooperation with the international community. At present, China has shared many technical documents on epidemic prevention and control with more than 100 countries and more than 10 international organizations and regions around the world, and translated the 7th edition of COVID-19’s diagnosis and treatment plan and the 6th edition of prevention and control plan into many languages for the reference of relevant countries and international organizations, which has effectively enhanced the global anti-epidemic ability and won wide acclaim from the international community. The epidemic is our common enemy. In the face of this struggle, which concerns the common interests of all mankind, all countries in the world should uphold the concept of win-win cooperation, strengthen policy communication and coordination, and work together to set up the strictest joint prevention and control network to fully curb the spread of the epidemic. It is necessary to gather the strength of all countries, work together to speed up scientific research on drugs, vaccines and testing, and strive to achieve breakthrough results that benefit all mankind at an early date. It is necessary to explore the establishment of a regional public health emergency liaison mechanism to improve the emergency response speed of public health emergencies.

　　Demonstrate the mission responsibility of a big country. It is the common responsibility of all countries in the world to build a community of human destiny and meet global risk challenges. Among them, big countries play a pivotal role and should take the lead in taking on greater responsibilities and play a mainstay role. In this anti-epidemic process, China took the lead in donating US$ 20 million to WHO, sending medical expert groups to some countries and regions with severe epidemic situation and weak health systems to provide anti-epidemic experience support and medical material assistance, and establishing an online knowledge center for epidemic prevention and control in COVID-19, which is open to all countries, making great contributions to the global anti-epidemic and showing the world feelings of upholding justice and helping each other in the same boat. Fighting the COVID-19 epidemic is a struggle, which requires the firm confidence, unity and cooperation of all mankind. As long as we help each other in the same boat, we will be able to completely overcome the epidemic and write a magnificent chapter in the community of human destiny.

The movie "A Huge Future" tells an absurd and wonderful story about the survival of the Jedi that Ma Shang (Bao Beier) and four trapped people with different identities jointly carry out. The "survival group" composed of all people should not only find ways to get out of trouble, but also fight with a crocodile in a circus. The fusion of genre elements of disaster and comedy, and the collocation of actors with different styles such as Bao Beier and Ming Dow bring more attention to the film.

Director Jiang Xiaotong said that "The Future is Huge" is the first attempt to integrate the two types of disaster and comedy, bringing a new form of expression to the story of little people. Bao Beier praised Ming Dow for his dedication, while Ming Dow said that he was moved by the director’s creative ideas and accepted the film with intuitive trust. Pan Binlong praised the film for its ingenious thinking, reversal and echo, and felt many intentions in film creation. Ashton Chen, on the other hand, talked about his cooperation with the two leading actors. Both of them showed extraordinary skills in the action scenes in this film, and they had an excellent viewing experience.

　　Comparison of Medical Insurance Negotiations from 2017 to 2020

　　Source: National Medical Insurance Bureau and Essence Securities Research Center.

　　After enterprise declaration, formal review and expert review, the national medical insurance drug list adjustment entered the negotiation stage in 2021. The reporter learned that the on-site negotiation of the medical insurance catalogue is about to begin.

　　Under the background of the rapid development of biotechnology and the accelerated rise of innovative drug industry in China, more domestic innovative drugs are accelerating to the medical insurance catalogue. According to institutional data, about 20 domestic innovative drugs will be negotiated for the first time, and the new indications that have been included in the varieties will be superimposed. In this round of medical insurance negotiations, investors have paid a lot of attention.

　　About 20 domestic innovative drugs were negotiated for the first time.

　　According to the previously published Work Plan for National Medical Insurance Drug List Adjustment in 2021 (referred to as the "Plan") and the medical insurance negotiation process in previous years, it is widely expected in the industry that this year’s medical insurance catalogue negotiation will start soon. The National Medical Insurance Bureau has previously made it clear that if the progress is smooth, this catalogue adjustment work will be completed before the end of this year, and efforts will be made to start implementation in January next year.

　　According to many brokerage research institutions, it is estimated that about 20 domestic innovative drugs will be negotiated for the first time this year, including PARP inhibitors, BTK inhibitors, ALK inhibitors, ADC drugs (antibody conjugated drugs), CAR-T therapy (chimeric antigen receptor T cell immunotherapy), etc., involving many listed pharmaceutical companies such as Beida Pharmaceutical, Baekje Shenzhou, Hengrui Pharma and Zejing Pharmaceutical. Among them, the CAR-T therapy, which is priced at 1.2 million yuan by Fosun Kate, has attracted much attention from the market. Some institutions pointed out that as a representative of expensive new technology, the negotiation result of this variety will closely affect the pricing of new technology products.

　　In addition, the anti-tumor drug PD-1 monoclonal antibody is still the focus. In the medical insurance negotiations in 2019 and 2020, the price reduction of PD-1 monoclonal antibody was remarkable. At present, the competition in the domestic PD-1 market is fierce. Ten PD-1/L1 have been approved for marketing, and new indications have been continuously approved, and the listing of new drugs has continued to accelerate. Ma Shuai, an analyst at Essence Securities, said that among the domestic varieties, the enterprises and varieties that are eligible to participate in the medical insurance negotiation in 2021 are still the four varieties that participated in the medical insurance negotiation last year, and the competition pattern of domestic varieties is relatively relaxed. It is expected that the PD-1/L1 monoclonal antibody will face fierce competition in the medical insurance negotiation in 2022.

　　Regarding the issue of price cuts that the public and investors are concerned about, Industrial Securities said that the current negotiation system for innovative medicine and medical insurance has gradually matured and improved, and it is expected that the future negotiation results will probably continue the overall price cuts in the past few rounds. Although the price reduction is not small, innovative drugs are successfully included in the negotiation list after the game of quantity and price, which will still bring incremental contributions to the corresponding varieties. Rapidly promoting R&D, seizing the first-Mover advantage and reasonable pricing strategy will become important factors in the market competition of innovative drugs.

　　Listed pharmaceutical companies are actively preparing for the war in order to increase the volume.

　　At present, many pharmaceutical companies are actively preparing for medical insurance negotiations. The third quarterly report disclosed by Baekje Shenzhou on November 5 shows that the company is preparing for the upcoming national medical insurance drug list negotiation for qualified products, including adding first-line treatment for non-squamous non-small cell lung cancer, first-line treatment for squamous non-small cell lung cancer and second-line or third-line treatment for hepatocellular carcinoma indications. On the 4th, Rongchang Bio disclosed the prospectus, saying that the company’s core products, Taitacip for the treatment of systemic lupus erythematosus and Videcituzumab for the treatment of gastric cancer, were approved for listing in China with conditions in March 2021 and June 2021 respectively, and the company is actively preparing relevant materials for participating in medical insurance negotiations, with a view to rapidly expanding the sales channels of products in a short time and effectively and rapidly promoting product sales. In the record of investor relations activities disclosed on the 2nd, Beida Pharmaceutical said that at the moment of a new round of medical insurance negotiations, the company is also actively docking the access of Kemena and Bemena.

　　Inclusion in the medical insurance catalogue has undoubtedly become an important catalyst for innovative drug volume. In July this year, the National Medical Insurance Bureau said in its reply to Recommendation No.9562 of the Fourth Session of the 13th National People’s Congress that after three years of continuous adjustment, a total of 233 drugs were successfully included in the medical insurance catalogue through negotiation, and the accessibility of patients to drugs was greatly improved, and the enterprise also reached the market sales expectation. Finally, the goal of "market for price" was realized. According to the data of Medicine Rubik’s Cube, a drug data platform, in 2017, 2018 and 2019, the sales of drugs that were included in the medical insurance catalogue through medical insurance negotiation increased by 128%, 337% and 39% respectively in 2020.

　　The Blue Book on the Progress and Effectiveness of Medical Insurance Drug Management Reform published by China Pharmaceutical Association and China Medical Insurance Research Association shows that among the 34 innovative drugs listed from 2016 to 2020, 26 drugs have entered the medical insurance catalogue, accounting for 76.5%. The time from listing to medical insurance for innovative drugs has also been greatly shortened. In 2017, it will take 4 to 9 years for new drugs to enter medical insurance, shortened to 1 to 8 years in 2019, and further compressed to 0.5 to 5 years in 2020.

　　Huachuang Securities believes that from the perspective of sales amount, except for some products with expired patents, most innovative drugs have achieved price-for-quantity exchange, and the amount has rapidly increased after entering medical insurance.

　　"Innovative drugs are expected to improve the difficulty of access after entering medical insurance, and achieve rapid penetration of hospitals and pharmacies." Ma Shuai analyzed that, on the one hand, after the drug enters medical insurance, it will be less difficult to obtain the recommendation application from clinicians, pass the preliminary selection of departments and finally pass the drug selection meeting in the hospital, which greatly reduces the difficulty of drug entering the hospital and lays a good foundation for the future drug in the hospital; On the other hand, in May this year, the National Medical Insurance Bureau and National Health Commission issued the Guiding Opinions on Establishing and Perfecting the "Dual-channel" Management Mechanism for National Medical Insurance Negotiation Drugs. After the drugs enter the medical insurance catalogue, it is expected that the "dual-channel" mechanism will accelerate the volume of products at the pharmacy side.
