The heart is one of the most important organs for us, and its existence and health affect our body and life.
There may be many problems in the heart, among which heart failure often makes people talk about it. Heart failure is the abbreviation of heart failure, which refers to serious cardiac insufficiency, that is, the systolic and/or diastolic function of the heart is impaired. It is not a disease, but an abnormal state that affects the whole body, which is caused by the gradual progress and aggravation of other primary heart diseases, resulting in the loss of compensatory ability of cardiac function, which leads to the inability of the heart to bear the normal physiological blood pumping demand. Heart failure is a state, belonging to a kind of organ failure, which is formed based on the gradual aggravation of some heart diseases themselves, and is often the end-stage manifestation of heart disease. Can be acute onset, chronic development, but also divided into left heart failure, right heart failure and heart failure.

There are many causes of heart failure. Infection: viral myocarditis, infective endocarditis, etc. Myocardial ischemia or pathological changes: severe coronary heart disease, dilated cardiomyopathy, etc. The structure of the heart is abnormal: complex congenital heart disease, long-term heart valve disease and so on. Almost all cardiovascular diseases, even improper drugs and excessive mood fluctuations may lead to heart failure.

Heart failure will have different manifestations according to the priority: acute heart failure is dangerous, with typical sitting breathing and obvious symptoms; Chronic heart failure often has no characteristic manifestations at first, and it is often labor-induced dyspnea at first. When it is seen in mild physical labor, it has obvious dyspnea and palpitation discomfort, and then it will suddenly wake up and have difficulty breathing during quiet sleep at night. Left heart failure is characterized by decreased activity ability and even inability to complete daily self-care; Right heart failure often has depressed edema of the lower limbs, mostly located in the ankle. After pressing with fingers, the swollen skin will not rebound immediately, and a small depression will appear. This is because of poor blood return caused by cardiac insufficiency.

Heart failure is the process of heart disease progression and the manifestation of the end stage of the heart. Whether it is terrible depends on the primary disease and the degree of progress. Acute heart failure, like viral myocarditis, is often very dangerous, and it will be life-threatening if it is not treated in time. As long as chronic heart failure is treated as early as possible, those patients with mild or moderate heart failure can still get a better prognosis. As for the popular saying that "patients with heart failure can only live for five years, which is more terrible than cancer", there is no such saying. Early detection, early intervention and treatment of heart failure can still achieve a better prognosis. With the development of medicine, many measures to treat end-stage heart failure, such as heart transplantation, artificial heart and ventricular assist, are being applied in clinic, which will greatly improve the long-term survival rate of patients with heart failure.

So, how to reduce the risk of heart failure? Except for a few diseases that cannot be treated at present, such as dilated cardiomyopathy, in most cases, as long as they are treated in time, they will not develop into heart failure. Therefore, active treatment of primary heart disease is the primary means to improve the prognosis of patients. Patients with heart failure need to treat primary heart disease first. At this time, patients often have a serious primary disease, so standardized treatment is more needed. In addition, we should pay attention to the following aspects: avoiding colds and preventing infections; Pay attention to diet, water and sodium retention in patients with heart failure can alleviate the above symptoms by reducing sodium intake; Control the amount of drinking water and monitor the inflow and outflow. If the long-term inflow is greater than the outflow, the heart burden will be heavier and heart failure will be aggravated. Pay attention to rest and avoid overwork; Patients with heart failure can be properly treated with diuresis, but diuresis also needs to monitor electrolytes and maintain electrolyte balance, especially potassium ions; Regular follow-up, do not adjust drugs without authorization; If you have obvious symptoms such as chest tightness, breath holding, and inability to lie flat, see a doctor in time.

　　A rare COVID-19 epidemic is raging around the world. The epidemic is the common enemy of all mankind, and unity and cooperation are the most powerful weapons and the only correct choice for the international community to overcome the epidemic. Anti-epidemic materials rushed to the international friendship city, doctors and experts went overseas to support, and cross-border connections shared anti-epidemic experience. Greater Bay Area’s strength in the global fight against epidemic, Guangzhou is in action.

　　01Epidemic prevention materials rushed to the international friendship city

　　Help each other in the same boat. Since the global outbreak of COVID-19, Guangzhou has actively organized epidemic prevention materials to help dozens of cities in more than a dozen countries.

　　Liu Baochun, director of the Foreign Affairs Office of the Guangzhou Municipal Government, said: "When there were epidemics in other countries in the world, we immediately extended a helping hand. We have issued three batches of materials, covering almost 40 cities, and some belong to corresponding international organizations. "

　　02Share Guangzhou’s anti-epidemic experience with the world

　　Guangzhou has been invited to attend online seminars on international epidemic prevention and control experience held by UN-Habitat, World Cities and Cities Organization, world association of major metropolises, C40 Urban Climate Leadership Alliance and World Cities and Cities Organization Asia Pacific for many times, and introduced Guangzhou’s epidemic prevention experience in detail in four seminars, vividly telling the epidemic prevention story in Guangzhou and accurately responding to foreign concerns and needs.

　　Tang Xiaoping, director of the Guangzhou Municipal Health and Wellness Committee, has participated in two sharing sessions: "I want to contribute our Chinese plan, or Guangzhou plan and Guangzhou wisdom through such video exchange. I think it is also very meaningful."

　　03 doctors and experts go overseas to support

　　A Chinese medical expert group sent by the Red Cross Society of China arrived in Baghdad International Airport from Guangzhou on the evening of March 7 to assist in the prevention and control of COVID-19 epidemic in Iraq. The expert group consists of seven experts, two of whom are outstanding backbones selected by the First Affiliated Hospital of Guangzhou Medical University.

　　Huang Kunjin, president of the First Affiliated Hospital of Guangzhou Medical University, said: "In addition to the test of epidemic situation, Iraq is also facing the test of personal safety. The two doctors showed great composure and confidence in their work. They helped the local people and the local government by introducing China’s prevention and control experience. "

　　04"Made in Guangzhou" helps the global fight against epidemic.

　　"Made in Guangzhou" epidemic prevention materials and testing reagents actively help the international anti-epidemic. Among them, Guangzhou Wanfu Biotechnology Co., Ltd. and Daan Gene Co., Ltd. donated or provided more than 100,000 test kits to Kyrgyzstan and Iraq.

　　The Red Cross Society of China donated a set of nucleic acid detection laboratory equipment to Iraq, which was provided by Sun Yat-sen University Daan Gene Co., Ltd.. Chairman He Yunshao said: "Not only reagents for 50,000 people have been prepared, but also nucleic acid detection instruments, extraction instruments and a complete set of laboratory equipment. There are more than 100 boxes, weighing about 3 tons."

　　Wanfu Bio is one of the first batch of diagnostic reagent manufacturers with "zero defect" approved by FDA in the United States. The three novel coronavirus detection products independently developed by Wanfu Bio have obtained CE certification issued by the European Union, which can meet the needs of rapid detection and prevention of epidemic situation in various countries.

　　Kang Keren, senior vice president of Guangzhou Wanfu Biotechnology Co., Ltd. said: "As of April 19, our products with more than 18 million people have been urgently sent to more than 70 countries and regions around the world. We are doing our best to help the country and the world fight the epidemic together. "

　　In Huangpu District, Guangzhou, where Wanfu Bio and Daan Gene are located, the Customs took the initiative to open a green channel to "accelerate" the export of foreign aid materials.

　　Li Hong, head of the Biosafety Supervision Section of the Health and Quarantine Department of Huangpu Customs, said: "At present, 68 batches of foreign aid reagents and 3.7 million people have been approved at an accelerated pace, with zero distance, full process and online approval, and the approval time has been shortened to one working day. From March to now, our approval volume has tripled. "

　　The epidemic is still spreading around the world, and global efforts to fight the epidemic continue.

　　As Academician Zhong Nanshan said, all people should unite as one world and fight against the epidemic together. For the sake of the community of human destiny, "epidemic" is obligatory!

　　Welcome to continue to pay attention

　　The Voice of Greater Bay Area, together with the media in various cities in the Bay Area, planned and produced a series of media-integrated programs, each focusing on one city and telling the story of Greater Bay Area’s participation in international anti-epidemic cooperation.

　　CCTV News:According to the website of the Ministry of Commerce, recently, seven departments including the Ministry of Commerce, the Development and Reform Commission, the Ministry of Finance, the General Administration of Customs, the State Administration of Taxation, the General Administration of Market Supervision, and the Foreign Exchange Bureau jointly issued the Letter on Accelerating the Pilot Work of Market Procurement Trade Mode, in order to implement the deployment of the the State Council executive meeting, develop new foreign trade formats, and foster new growth momentum, and set up eight new market procurement trade mode pilots.

　　The newly established pilot projects are: Tianjin Wang Lan Zhuang International Trade City, Hebei Tangshan International Trade Center, Jilin Hunchun Northeast Asia International Commodity City, Heilongjiang suifenhe city Qingyun Market, Jiangxi Jingdezhen Ceramic Trade Market, Chongqing Dazu Longshui Hardware Market, Xinjiang Alashankou Asia-Europe Commodity City, Xinjiang Urumqi Frontier Hotel Trade Market.

　　Previously, seven departments, including the Ministry of Commerce, had set up 31 pilot market procurement trade modes nationwide, and built a supervision system of "one demarcation, three filing and one networking", with supporting policies such as simplified declaration and non-refundable VAT exemption. The development of market procurement trade has achieved positive results.

　　In the next step, the Ministry of Commerce, together with other departments, will guide the newly established pilots to speed up the introduction of implementation plans, build a networked information platform, implement supporting policies, continuously improve the level of trade facilitation, promote the sustained and healthy development of market procurement trade, and help foreign trade maintain stability and improve quality.

　　[News] Friends who plan to buy electric cars, charging is undoubtedly a problem that needs to be considered before buying a car. At present, there are two main ways to charge electric vehicles, one is to use public charging piles, and the other is to charge at home. At present, when charging with public charging piles, car owners have to face the problems of long waiting time for charging and trouble in finding charging piles, so it is the most ideal choice if they can have a charging pile at home. For electric vehicle manufacturers, home charging is naturally one of the charging methods actively promoted, so how do manufacturers do it? What services are provided to consumers? In this paper, we have selected five brands with high sales volume and attention from China brands, joint venture brands and imported brands, namely,,, and. Let’s talk about the installation services of household charging piles of these brands.(The names of charging piles provided by various manufacturers for personal use are different, and this article is collectively referred to as household charging piles.)Next, let’s get into the text together.

　　◆ BYD

"with pictures"

　　Let’s start with BYD, which is very concerned. At present, BYD’s new energy vehicles include both pure electric vehicles and plug-in hybrid vehicles, including BYD e6, Qin and Tang. Take BYD e6 as an example. This car has a battery life of 300km. There are three charging methods: public charging pile, portable (socket) charging and wall-mounted charger (household charging pile).(Note: For hybrid vehicles such as Qin, the installation and use of household charging piles in cities where plug-in hybrid vehicles cannot enjoy subsidies may be different from this article.)

　　● Basic situation of BYD household charging piles

　"The picture shows BYD’s standard 3.3kW household charging pile for Qin"

　　BYD e6 comes standard with a household charging pile with a power of 7kW, which uses a voltage of 220V, and it takes about 10 hours to fully charge it. In terms of charging cost, the residential electricity price is adopted, and the settlement method refers to household electricity consumption.

　　In addition, BYD e6 also has a 40kW charging pile for consumers to choose from. The charging pile uses 380V voltage, and it takes about 2-2.5 hours to fully charge. It uses industrial electricity price, and the settlement method is the same as household electricity. You need to pay extra when you choose to install the charging pile, but the dealer’s quotation is not the same. Among the dealers we consulted, some said that replacing 40kW charging pile with 7kW charging pile should pay 6500 yuan; Some dealers say that the 40kW charging pile sells for 12,000 yuan, and the price is 9,000 when it is replaced with 7kW charging pile. Some dealers also said that the price needs to be discussed in detail at the store.

　　The household charging piles provided by BYD have no locking function that can restrict the use of others. From what we know, most BYD car owners have installed the charging piles in a power distribution box, and the box can be locked when not in use.

　　● Installation Service Description

　　During installation, BYD needs consumers to have fixed parking spaces or parking spaces where charging piles are allowed to be installed. Some dealers expressed their willingness to provide some assistance when consumers communicate with the property.

　　We learned from BYD’s official customer service that BYD does not provide free installation service for charging piles now, but when we consulted dealers, we learned that some dealers will provide free installation service, while others will provide paid installation service, and all of themIt was installed by a third-party service provider. In terms of installation cycle, the dealer said that as long as conditions permit, the installation of charging piles can generally be completed on the day of picking up the car.But there is no clear time commitment. In addition, dealers only provide installation services to consumers who buy new cars in the store, and will not provide installation services if they buy cars in different places.

　　● Summary:

　　BYD provides e6 owners with two kinds of household charging piles to choose from, and the combination of fast and slow provides consumers with more choices. However, BYD’s official website did not give a detailed description of household charging piles, nor did he mention what kind of policy support he would enjoy when installing household charging piles. The information is not transparent enough, so it is difficult for consumers to know more information. Moreover, there are differences among dealers in details such as the price of 40kW charging piles and whether the installation is free. It can be seen that BYD does not have a particularly clear standard for the installation service of household charging piles, and it is difficult for consumers to enjoy unified services.

　　◆ Beiqi New Energy

『』

　　At present, Beiqi New Energy mainly puts ES210 models on the market, and the maximum cruising range of these models is generally between 220-245km. At present, Beiqi New Energy provides four charging methods for its models: public charging piles, Beiqi electric piles, socket charging and household charging piles.

　　● Basic situation of Beiqi New Energy Household Charging Pile

"Beiqi New Energy Household Charging Pile"

　　BAIC New Energy can give free home charging piles to consumers who meet the installation requirements. The charging piles use 220V voltage, and their charging speed is consistent with the national standard slow charging piles, which takes 6-8 hours to fill a car. In the aspect of charging cost, the civil electricity price is adopted, and the settlement method is to brush the special electric card every time.

　　It is worth noting that all the charging piles of BAIC New Energy have no password locks or other locking devices, which means that other models with national standard interfaces can use the charging piles to charge at any time as long as they have special electric cards for electric vehicles.

　　● Installation Service Description

　　You can apply for installing a home charging pile when you buy a new energy vehicle of BAIC, and the requirement is that you need a fixed parking space. When there is no fixed parking space, if we can negotiate with the property, we can also install charging piles in specific places.

　　At present, Beiqi New Energy is mainly related toState GridCooperate to provide installation services for charging piles. If the installation conditions are met, the construction party can complete the installation and power connection within 10 working days. After consulting 4S stores, we understand that dealers only provide installation services to consumers who buy cars in our stores, and it is impossible to install them if they buy cars in different places.

　　● Summary:

　　Because BAIC New Energy has many customer bases in other regions, the installation service of its household charging piles is relatively perfect, and consumers can learn most of the problems and detailed installation procedures on its official website. However, there are also some problems that will bring inconvenience to consumers. First, the charging pile has no protective measures, and others can use their own parking spaces and charging piles to charge at any time as long as they have charging cards. Secondly, the warranty business of charging piles requires consumers to contact the charging pile manufacturers themselves, which brings more use costs to consumers.

Original title: 360′ s fast video APP releases short videos and is about to usher in the era of quality content.

In the past year, the short video industry has developed rapidly, and short video has become a new direction of investors’ attention. However, short video platforms emerge one after another, which is too demanding for quantity rather than quality, which directly leads to the difficulty in controlling short video content, and the quality of short video content has become the key to the development of short video industry.

Photo: 360 founder and CEO Zhou Hongyi delivered a one-minute speech.

On November 14th, 360 Express Video held an ultra-short video app-Express Video Conference in Beijing. At the conference, Zhou Hongyi, founder and CEO of 360 Group, gave a short speech for one minute, proposing to watch the video for one minute, so that every second of the video will be more exciting and busy people can watch interesting and informative videos in the shortest time.

A one-minute story only looks at the essence, only the essence.

As the first ultra-short video APP in the whole network, Fast Video has specially created a "1-minute series" column, which clips the wonderful scenes of film and television works to one minute, allowing users to watch the wonderful contents of the current wonderful film and television works in one minute, and quickly obtain the key points of the long drama series, compressing the entertainment time to one minute, but expanding the entertainment effect to the satisfaction of users.

One minute of ultra-short video naturally can’t make users wait for time. 360 Fast Video introduces the functions of fast playing and fast preview of ultra-short video, allowing users to see the climax of ultra-short video in one second, without wasting a minute or a second of entertainment time.

Fast video each video is only one minute long, which makes users worry about the integrity of the video story. Fast Video Select short videos with high quality for 1-3 minutes, and compress the story so as to finish a story in one minute.

Based on the background of 360 big data and artificial intelligence, Fast Video adds leading image vision artificial intelligence technology on the basis of other video platform technology reserves, and each released video is screened by the technical background, so that every work pushed to the client has quality and connotation, and can tell a story completely. Let users capture the wonderful in one minute and appreciate the wonders of the world in one minute.

Intelligent exploration engine helps users explore new fun.

The most common browsing mode of short video platforms is to push the updated content in the background immediately. Users browse in real time, and the video label is not obvious. Users often receive content that they are not interested in, so they can only skim over the uninterested content and skip to the next one.

Fast Video is a new generation of QVD intelligent exploration engine, which senses and records users’ emotions every time they browse video content, and analyzes users’ preferences through the background system. When the user browses the short video content next time, the background will be pushed to the client according to the user’s preference.

In addition to analyzing the length of time users watch videos, the free search function of fast videos is also one of the ways for the system to obtain users’ preferences. The fast video system strengthens the user’s emotional perception and free exploration, so that users can not only see interesting content, but also find other kinds of wonderful videos, bringing more excitement to users’ entertainment time.

Improving the quality of short video from the production team

The quality and connotation of short videos are inextricably linked with short video producers and teams. In order for users to watch fresher and better quality video content, Fast Video pays special attention to the video team.

Up to now, the fast video team has settled in tens of thousands of original video organizations and teams. At the same time, Fast Video said that Fast Video will invest 10 billion yuan to build an ultra-short video ecosystem and set up a fast fund plan.

In order to support video producers with ideas, but the technology is not up to standard for the time being, Fast Video provides a permanent and free editing tool-Fast Editing, aiming at providing a broader growth space and more lucrative returns for each video author.

Fast video starts with video content and strives to create an ultra-short video APP with high quality. It is worth looking forward to whether the fast video can enhance the awareness of short video platform content.

Original Dr. Ni from NiNi, Florida, in the United States.

After this year’s college entrance examination mathematics examination paper came out, there was a cry of bitterness on the Internet. As an American math teacher, I also looked at it curiously. Frankly speaking, it can only be described in one word: Meng.

There is no college entrance examination in the United States, only the SAT or ACT exam similar to the college entrance examination. My son, who is in senior three, took a naked SAT math test this year, with a total score of 800 points and a score of 740. This achievement ranks among the top 5% in the United States, and he still has one year to graduate (four years in American high school). Is it difficult to ask him a question? He said it was very simple, and all the tests were the most basic contents.

Compared with Chinese college entrance examination mathematics, what are the characteristics of American SAT mathematics?

1. Most of the topics are multiple-choice questions.

The mathematics part of the SAT is 80 minutes, with 58 questions, of which 45 are multiple-choice questions, and only 13 need to fill in the answers by themselves. The latter will be a little more difficult because it is easier to make mistakes.

I have taken several exams in the United States, and most of them are single-choice questions. The advantage of multiple choice questions is that you can guess the answer, and the error rate is also lower. For example, if there is a slight deviation in the calculation, you will find that there are no required options in the answer and you can’t check it again. Comparatively speaking, there are four kinds of math problems in China’s college entrance examination: single choice, multiple choice, filling in the blanks and solving problems, especially the last kind of solving problems, which needs to be reasoned, proved and solved step by step. It is really not easy.

2. Pay more attention to basic concepts

From the topic, American SAT mathematics pays more attention to the understanding of basic concepts.

The figure below shows the SAT’s examination of mathematical ability. It is divided into four categories, including core algebra, problem solving and data analysis, introduction to advanced mathematics, and other mathematical topics. The last item is related to interdisciplinary topics of mathematics and social sciences.

Taking the introduction of advanced mathematics as an example, the required abilities are: 1) identifying and creating algebraic equations; 2) Create, analyze and solve quadratic equations and other nonlinear equations fluently; 3) Create, use and draw charts of exponential equations, quadratic equations and other nonlinear equations. None of this exceeds the content of algebra 2.

Here are two sample questions to give you a rough idea of the difficulty.

3. The weight of SAT in American college entrance examination

Compared with the official nature of China’s college entrance examination, the American SAT is set and evaluated by the third-party university committee of the non-profit organization. Different from the Chinese college entrance examination, the admission of American universities depends on the GPA, specialties, community activities, community services, and application documents of students in high schools. The SAT is only used as a reference.

In recent years, American educational circles have been debating whether to cancel the SAT, but so far, the SAT is still a very important reference. If you do well in the exam, you will still have a considerable advantage in college admission.

Another difference of SAT is that you can take it many times and get the highest score. The following is the examination time for the 2022-2023 school year. In one school year, there were seven examination opportunities. Therefore, even if you don’t do well in the exam for a while, you won’t feel that the end of the world is coming. Just take the exam next time.

4. Emphasis on concepts in American mathematics teaching.

American mathematics teaching attaches great importance to concepts. One feeling is that sometimes I have to spend a lot of time teaching vocabulary. For example, there are as many as 12 words in the chapter of teaching geometric figure changes, and teaching vocabulary often becomes a difficult problem: how can students understand and remember it more easily?

For another example, American teachers attach great importance to the process of teaching unary equations.

I remember when we were in China, we learned to move all variables to the left and numbers to the right, but we had to change the sign. The United States emphasizes the meaning of "equation", and all operations should not exceed the line of "equal sign". Add a number to the left and a number to the right, as well as multiplication and division, so as to maintain the balance on both sides of "equal sign". Compared with mathematics teaching in China, it is much more complicated, but easier to understand.

Therefore, I take the best of both, teaching with the American method, and doing my own problems with the China method, because it is much faster.

Look at Chinese’s criticism of the deviation of the math college entrance examination questions, while Americans are also criticizing their math education problems, and some also compare China and think that American math education is much behind China. In my opinion, there are only different ideas, and each has its own views on which is better or worse.

Do you prefer the math college entrance examination in China or the SAT math exam in the United States? Welcome to vote. Also welcome to leave a message for discussion.

In the dangerous tropical jungle of Yumanji, several people became Dr. Yong Shi, Maozi Fenba, Professor oberon and Ruby with Iron Fist respectively. Faced with the attack of jungle beasts and the pursuit of evil forces, the four must work together to overcome many crises and win the game in order to get a chance to return to reality.

This week’s movie channel "A Good Movie with a Date" column, let’s follow the footsteps of several brave people and experience the jungle adventure together in "The Game of the Brave: The Battle of the Jungle"!

Classic IP innovation restart

Before The Game of the Brave: The Battle of the Jungle, there were actually two movies of The Game of the Brave. The first one that we are most familiar with was released in 1995. At that time, as one of the ten imported blockbusters in 1996, the film was released in China and became the collective memory of a generation.

Twenty-two years later, the story of "The Brave Game: The Battle of the Jungle" continued the end of the first film, so why did this series of movies have such strong vitality?

In 1981, Chris Van Olsberg, an American children’s literature writer, finished drawing this book. At first, the book contained only 32 pages and 14 illustrations, but it won the title of Oscar in the picture book industry the following year for its imaginative ideas. — Kadik Award.

With the foundation of the story, The Brave Game was successful because a very suitable hero was selected at that time.

The Brave Game starring robin williams reminds fans of Yumanji. In 2014, Williams, known as a comedy master, chose to leave this world because of depression, and we can never see his return in this series. However, Game of the Brave: Battle of the Jungle chose a very suitable candidate to take over Williams.

The formation of megaliths

Childhood Qiang Sen was ugly and even a little thin, and he couldn’t see the big guy in the future at all. That’s because Qiang Sen’s family was very poor for a long time, and his father who fought in the American professional wrestling league couldn’t bring a stable income to this family. At the age of 16, Qiang Sen was so poor that he was only $7 from his apartment to the street. At that time, his life turned around, and he became Dwayne Douglas Johnson today with two choices.

The first choice comes from: wrestling　

After entering high school, Qiang Sen gradually showed his athletic talent. He hoped that his son would follow in his father’s footsteps and engage in wrestling. At first, his father firmly opposed it. He didn’t want his son to live a precarious life like him in the future, but Qiang Sen was very determined. He insisted on getting up at 4 am every day for training. In the end, he not only gained recognition, but also won eight American professional wrestling league championships under his father’s training.

The second choice comes from: movies.

Qiang Sen’s strong acting talent and body language have attracted a lot of media attention, as well as from film companies. So in 2001, at the age of 29, he chose to appear in the first film of his life and became a film actor.

The return of the mummy movie clip

In recent years, when he gradually became the highest-paid actor in the world, he chose to name his film company "7 dollars". He said, "It is really surprising to become the highest-paid actor. I don’t have a high degree from Harvard University, but with my failure, I have made continuous progress, and I will never forget those experiences."

In 2016, Qiang Sen and his $7 film company participated in the first project, The Brave Game: The Battle of the Jungle. He not only starred in the film, but also assumed the role of producer. Therefore, we can see in the film that under his arrangement, the crew went deep into the Hawaiian rainforest to shoot and successfully created the Yumanji world full of beasts.
