  The Long March 7 came into being: the fuel is more environmentally friendly and the carrying capacity is stronger.


  With the continuous development of China’s space industry, the demand for the construction of space stations and the launch of high-quality satellites began to appear, but the older generation of launch vehicles could not meet the demand. In order to carry these massive cabins and satellites, it is necessary to develop a new type of large-capacity rocket. Moreover, the older generation of Long March rockets used a lot of highly toxic hydrazine-nitrogen tetroxide fuel. From the point of view of protecting the natural environment and working environment, it is also necessary to develop a new type of environmentally friendly launch vehicle.

  

[1] You can see the rolling red smoke of nitrogen tetroxide, which is not only highly toxic, but also a destruction of the ozone layer.

  In order to meet the power demand of new launch vehicles, new rocket engines are essential.


  Thus, in 2001, YF-100 liquid oxygen/kerosene engine with 120 tons thrust and YF-77 liquid oxygen/liquid hydrogen engine with 70 tons thrust were approved. The Long March 5, powered by these two engines, also entered the public eye in 2006.


  Two years later, in order to meet the launch demand of small satellites, Long March 6 was also launched in 2008. Its core stage used a single YF-100 engine, and its secondary stage used a single YF-115 liquid oxygen/kerosene engine with 18 tons of thrust.

  

[2] The Long March 6 equipped with YF-100 engine is very different from the take-off effect.

  The largest LEO (low Earth orbit carrying capacity) of Long March 5 is 25 tons, and the smallest LEO is 10 tons, while the SSO (sun synchronous orbit carrying capacity) of Long March 6 is 0.5 tons, and LEO is about 1 ton.


  In order to fill the gap between Long March 5 and Long March 6, and to provide vehicles for future cargo ships, Long March 7 was put forward in 2010. In fact, the Long March 7 is almost a replica of the Long March 2-the 3.35-meter diameter core stage and the 2.25-meter diameter booster stage, which inherited the configuration of the Long March 2, but at the same time combined with the new rocket engine, which is really innovative.

  

[3] When the two rockets were launched together, the Long March 7 was obviously much thinner.

  The first stage of Long March 7 core adopts double YF-100 liquid oxygen kerosene engine, the four booster stages adopt single YF-100 liquid oxygen kerosene engine, and the second stage adopts four YF-115 engines. The successful test launch of Long March 6 last year has already declared that these two engines are very successful products. Therefore, the successful launch of the Long March 7 can be said to be fully guaranteed.

  

[4] In the assembly workshop of Long March 7, we can easily identify the corresponding position of each arrow.

  What is the main purpose of the Long March 7? Transport the ship!


  The main purpose of the Long March 7 in the future is to carry the "Tianzhou" series of cargo spacecraft and give them to the astronauts in the space station. At the same time, the successful operation of the upper stage of Expedition 1 last year, the appearance of the upper stage of Expedition 2 this year and the possible new low-temperature upper stage in the future can also give more functions to Long March 7-it will help the satellite to go into geosynchronous orbit (GTO), so that Long March 7 has enough ability to replace some existing launch vehicles.

  Besides Wenchang Chicken, Wenchang also has a satellite launch center.


  The successful launch of the Long March 7 also announced the official opening of Wenchang Satellite Launch Center.


  Why should the new launch center be located in Wenchang? Of course, Wenchang has many advantages:


  As we all know, the lower the latitude, the faster the linear speed of the earth’s rotation, which can make the rocket carry more loads. The latitude of Wenchang Satellite Launch Center is only 19, which is a very favorable position.

  

[6.1] Location of Wenchang Satellite Launch Center

  2. Because the first-class diameter of the core of Long March 5 has reached 5 meters, it means that it can’t be transported by land-because it can’t cross the tunnel; Not by air-planes can’t transport things with such a large diameter. Therefore, shipping has become the only feasible way. The rocket body made in Tianjin can easily reach Wenchang by water.

  

[6.2] The Long March 7 packed boxes at Tianjin Port, and its destination was Wenchang.

  3. The launching direction of rockets is basically east and south. This means that the burned remains of the booster and first-stage rockets will fall to the east and south. The east and south of Wenchang are near the sea, which means that the debris of the rocket will fall directly on the sea surface, which fundamentally avoids the risk of debris hitting people.

  

[6.3] Wenchang Satellite Launch Center

  Many foreign space centers also refer to these elements. The Kennedy Space Center in the United States is the Atlantic Ocean to the east, with a latitude of about 28; The Kulu Space Center of ESA is also near the sea, and its latitude is only 4, which is close to the equator. It’s really enviable …

  

【 7.1 】 The Kennedy Space Center, located in Cape Narr, Karaoui, has the Atlantic Ocean on the right.

  

[7.2] The Caribbean Sea is clearly visible above the Kourou Space Center of ESA.

  When the photos of the Long March 7 joint training were released last year, many people noticed the transformation of the launcher-the huge launch tower in the past was replaced by a simple launcher. In the launch of Long March 6 last year, this technology was also adopted, and even further-transshipment was directly carried out by the launch vehicle.

  

[8] What about the wheel of the transfer car? σ (△|||)? It turned out to be too small? (╯ ▽)?

  In the previous launch preparation process, our rocket had to be transported vertically from the assembly center to the launch tower, with almost no support. Because the rocket is very high, its center of gravity is also very high. When the wind is too strong, the transshipment work is quite dangerous. This is also unfavorable for rocket launch preparation.

  

[9] Such a big luck, without any assistance … Did you panic?

  In the past, the launch tower served as a rocket assembly room, so it was made so big. However, with the increase of rocket launch frequency, the launch preparation time is gradually shortened, and vertical transshipment can meet this requirement. With the development of technology, the current launch tower has only the functions of fixing and fuel filling, which can be done very lightly, making it possible to transport the arrow with the frame, thus reducing the requirements for the environmental conditions of transshipment. Of course, because the launch tower can’t be abandoned easily, and the transfer track from the assembly plant to the launch tower is fixed, the rockets in the other three launch centers can’t enjoy this treatment.

  

[10] Can you imagine the whole umbilical tower coming out of the assembly room?

  Playing a rocket is also a relatively expensive thing. I’m sorry if I don’t take this opportunity to bring a little load. Last year’s launch of Changliu carried 20 satellites at once, all of which were in orbit and successfully monitored and controlled. The Long March 7 is no exception. It brought a heavyweight passenger-a small-scale model of a new manned spacecraft.

  

[11] Do you see any difference in the design of the new manned spacecraft?

  The Shenzhou manned spacecraft now in use in China is well known to all. It draws lessons from the structure of the orbital module, return module and propulsion module of the former Soviet Union Soyuz spacecraft, so it also designed three cabins.

 

[12] This is a brotherly spaceship.

  The new manned spacecraft, except the orbital module, consists only of the command module and the propulsion module, which is closer to some American spacecraft.

  

[13] The new manned spacecraft is closer to the American spacecraft, with a western flavor …

  So why remove the orbital module?


  From the development of spacecraft, the orbital module is a multifunctional module, which is essentially a stopgap measure without a space station. Astronauts can carry out activities in the orbital module and also carry out some experiments. Moreover, China’s Shenzhou orbital module can still operate in orbit for a period of time, providing more abundant data. In particular, on Shenzhou VII, the orbital module was also transformed into an airlock module by magic, which became a transitional module for spacecraft/space environment.


  However, with the proposal of the space station plan and the successful operation of the "Tiangong" series of orbiters, astronauts have been able to have a more comfortable working and activity environment, and the orbital module has gradually lost its significance. When we remove the orbital module, the return module and the propulsion module can be made bigger, thus carrying more passengers and more fuel. It will lay a solid foundation for further manned space work (even manned moon landing) in the future.


  Words written outside the article: two different sizes of propulsion modules really seem to be preparing for manned landing on the moon.

Please put on two more clothes before reading this article, because knowledge is a little cold. To tell the truth, I have already prepared my mind, and the reading volume may not be very high, but you don’t know, this is the basic knowledge of nutrition. After learning, you will know that keeping in good health is such a simple thing.

Just as building a house requires laying a foundation, dogs, as a popular science worker, must teach you these basic knowledge so that you can learn better and more steadily.

Therefore, please read this article patiently, and you will gain a different life. Starting today’s program, how can dietary fiber be used? Why does your impression of it only stop at losing weight? Is all this a distortion of human nature or a moral decay? Welcome to "Approaching Science": Dietary Fiber-the Guardian of Human Health.

Next you will see:

1. What exactly is dietary fiber?

2. How strong is dietary fiber?

3. Food sources of dietary fiber

4. Three misunderstandings of dietary fiber

Nutrition experts are always reminding: to eat more dietary fiber, what is it? The professional definition is: polysaccharide that exists in plants and cannot be digested and absorbed by human body. Speak human words …

First of all, as long as the food grows in the ground, it contains dietary fiber, not just vegetables, fruits and whole grains you think. Like mushrooms and nuts, they are also rich in dietary fiber (which we will talk about later).

Secondly, dietary fiber is a kind of carbohydrate, which can be divided into simple and complex schools. Dietary fiber is a disciple of polysaccharide under complex schools, and this disciple is very different.

Why is it different? Because it can neither be digested nor absorbed by the human body, nor can it provide energy for the human body. See? Why do people think of losing weight when it comes to dietary fiber? I think the root cause lies here. So, dietary fiber seems to be useless, a waste? No, outstanding people are often different. Dietary fiber has made great contributions to our human body. Read on.

Before clarifying this question, let’s learn about the classification of dietary fiber.

1. The classification of dietary fiber

Water solubility, as the name implies, means that this kind of fiber can be dissolved in water, just like cement, which will swell up after absorbing water and make the food ball sticky. For a simple example, when people soak oatmeal, have you noticed that it becomes sticky after a long time? This is due to the water-soluble fiber in oats.

Although water-insoluble dietary fibers are insoluble in water, they are mixed in the food ball, just like steel bars, which is beneficial to prop up the food ball and make it bigger, thus increasing satiety and stimulating intestinal peristalsis. They are inseparable friends, and most plant foods contain both dietary fibers.

2. The role of dietary fiber

It is precisely because dietary fiber can get rich when it meets water, oh no, it gets fat when it meets water, and it is firmly bonded with other substances, so the health effect is increasing.

First of all, of course, it is well-known to lose weight.

Controlling weight is beneficial to losing weight.

Reason: The combination of dietary fiber and food can increase the volume and consistency in the stomach and increase the feeling of fullness, thus making you eat less. Plus it can’t provide energy, which helps you reduce your energy intake.

Reduce serum cholesterol and prevent heart disease.

Reason: Here we want to talk about a substance called bile acid, which is a component of digestive juice and secreted by the liver, and can promote our body’s absorption of fat and cholesterol.

However, dietary fiber can adsorb bile acids.

With less bile acid, the absorption rate of fat and cholesterol will decrease, which is beneficial to the decline of blood lipid, which also reduces the risk of coronary heart disease.

Conducive to controlling blood sugar and maintaining balance.

Reason: First of all, dietary fiber will not increase blood sugar because it will not be digested and absorbed by the intestine and will not provide energy. In addition, dietary fiber mixed with chyme can also reduce the absorption of sugar in food by small intestine, thus slowly raising blood sugar.

Because dietary fiber comes forward, the pancreas does not need to secrete so much insulin to metabolize sugar, which also reduces the working pressure of the pancreas, thus reducing the occurrence of diabetes.

Conducive to the growth of intestinal probiotics

Reason: Water-soluble dietary fiber can be fermented by intestinal bacteria to synthesize short-chain fatty acids, which is a hotbed for probiotics. Short-chain fatty acids can also adjust the PH value of the intestine, which is more conducive to the growth of probiotics. When probiotics are strong, harmful bacteria in the intestines can’t make waves, and the intestines are healthier.

Enhance intestinal function, which is beneficial to waste discharge.

Reason: As we said just now, dietary fiber expands when it meets water, and when it is combined with stool, it can make it bigger and softer, which is beneficial to the discharge of stool, and cellulose can also promote intestinal peristalsis, which accelerates defecation.

In addition, dietary fiber will be discharged with a small amount of cholesterol, fat and heavy metals in food, and you will feel light and relaxed.

Prevention of colon cancer

Reason: The time of defecation is accelerated, which also means that it stays in the intestine for a shorter time, which can prevent carcinogens from contacting with the easily infected intestinal mucosa for a long time, thus reducing the possibility of canceration.

The above six points are the efficacy of dietary fiber. See, it is simply a warm man who cares about everything and has a central air conditioning level!

In this era of obesity, diabetes and heart disease, dietary fiber is the hero to save mankind!

Hurry up and pass it on to those people around you who don’t like fruits and vegetables, and let them see what a pity it is!

Since dietary fiber is so great, which foods have high dietary fiber content? Please accept this form.

(Click to enlarge)

Here, dogs want to focus on the category of vegetables. Generally speaking, the dietary fiber content of wild vegetables is higher than that of cultivated vegetables, and dark green vegetables are higher than that of light-colored vegetables.

So, are all vegetables high in dietary fiber?

No, usually fruit vegetables, such as tomatoes (0.5%), cucumbers (0.5%) and wax gourd (0.7%) are relatively low. So, you should know which vegetable to choose for constipation!

After seeing the last row of nuts, friends who want to lose weight and want to eat nuts can choose almonds.

Dietary fiber has so many benefits, so is it better to eat more?

No, too much intake is not good for human body, because dietary fiber can be combined with iron, calcium, zinc, etc., thus affecting the absorption and utilization of these elements, which will lead to malnutrition in the long run.

The standard is to consume 30g every day. Take tremella with high content in mushroom as an example. Eating about 100g is equivalent to 30g of dietary fiber. However, dogs don’t advise you to eat a single food to meet your needs, but to diversify your food. Unfortunately, according to statistics, the dietary fiber intake of Chinese residents is far from the standard.

Come on! You, with your plain appearance and average qualifications, finally have a chance to get ahead!

I hope that in the future dinner, everyone will stop vomiting-inducing toasts, but

In order to help people make better use of it, the dog lists the questions that people often ask me and answers them uniformly.

1. Is the dietary fiber content of vegetables with tendons higher than that of vegetables without tendons?

NO! This truth is like a real rich man. You may not see that TA is wearing any famous brand from head to toe, but you really just can’t see it. For example, sweet potato does not contain gluten, but its cellulose content is much higher than that of Chinese cabbage with gluten. In addition, as we mentioned just now, there is no gluten in fungus, tremella and laver, but the dietary fiber content is very high.

2. Does chopping and breaking vegetables lose the healthy function of fiber?

Not really. Fiber can not be digested by human small intestine, so it can play a healthy role and will not be changed by physical treatment. Whether it is chopped or boiled, it will not change.

Yes, it is not afraid of chopping!

Studies have measured the swelling power and water-holding capacity of dietary fiber from burdock residue, and the swelling power and water-holding capacity of dietary fiber are basically unchanged when it is crushed in the range of 355um-250um. However, under normal circumstances, we don’t need to break it too much, because other oxidizable nutrients will be lost, and secondly, we will eat more food.

3. Does the more dietary fiber you eat, the more you lose weight?

Dietary fiber absorbs water and expands in the stomach, resulting in satiety, reducing eating other foods and really helping to lose weight. However, if you eat dietary fiber without reducing the intake of other foods, it will not help you lose weight.

At present, there are many biscuits with high dietary fiber on the market, saying that they can lose weight. The dog wants to explain that you may get fatter and fatter as you eat them. Because dietary fiber can’t be digested, especially insoluble dietary fiber, the taste is not good. In order to avoid stinging, a lot of oil will be added to improve the taste. You may eat more fat than dietary fiber, so don’t be superstitious.

That’s all for today’s cold knowledge. I believe you will work hard to reach the standard and win at a healthy starting line. After all, something good will happen to those who live long enough.

Summary: the role of dietary fiber

1. Weight control is beneficial to lose weight.

2. Reduce serum cholesterol and prevent heart disease.

3. It is beneficial to control blood sugar and maintain balance.

4. Conducive to the growth of intestinal probiotics

5. Enhance intestinal function, which is beneficial to waste discharge.

Online celebrity blogger was subjected to domestic violence: Chen Mou was detained for 20 days for intentional injury.

  On November 25th, after Weibo’s "YUYAMIKA" (He Moumou, female, 28 years old) reported on the Internet that she had been subjected to domestic violence by her ex-boyfriend Weibo’s "Tuotuo Feng Mo Jiao" (Chen Mou, male, 44 years old), the relevant departments immediately investigated and dealt with it.

  After investigation by the public security organs in Jiangbei District, Chen Mou repeatedly committed illegal acts of intentional injury to He Moumou from the beginning of April 2019 to the end of August 2019 (He Moumou’s injury degree was less than minor injury or above). In addition, it was found that Chen Mou also committed illegal acts that threatened the personal safety of others through WeChat. In view of the above-mentioned two illegal acts in Chen Mou, the public security organs respectively imposed administrative penalties according to the Law on Public Security Administration Punishment, combined with administrative detention for 20 days, and imposed a fine.

  In order to prevent Chen Mou from intentionally injuring him again, He Moumou applied to Jiangbei District People’s Court for a personal safety protection order on November 27th. At present, the hospital has made a personal safety protection order for He Moumou according to the facts identified after examination. (CCTV reporter Yan Liang)

How can we get mathematical thinking? Expert: Doing the problem is the first way.

  Cryptologist Wang Xiaoyun recently won the 2019 Future Science Award for Mathematics and Computer Science. She puts forward the collision attack theory of cryptographic hash function, which promotes the design of a new generation of cryptographic hash function standards, has been widely used in important fields such as finance and transportation, and has made important contributions to supporting network information security.

  Mathematics, as the foundation of natural science, its strength often affects the national strength. Almost all major discoveries are related to the development of mathematics, which is an indispensable basic tool for studying and studying modern science and technology.

  A few days ago, the Ministry of Science and Technology, the Ministry of Education, the Chinese Academy of Sciences and the Natural Science Foundation of China jointly formulated the Work Plan on Strengthening Mathematical Science Research, which emphasized the importance of mathematical research.

  Mathematics is the foundation of natural science and major technological innovation and development, and has become an indispensable and important support in the fields of aerospace, national defense security, biomedicine, information, energy, ocean, artificial intelligence, advanced manufacturing and so on. So, what is the essence of mathematics? The Economic Daily reporter interviewed professional math researchers and math enthusiasts, trying to solve it.

  How to understand mathematical thinking

  Zhou Chuan, an associate researcher at the Institute of Mathematics and Systems Science of China Academy of Sciences, believes that the essence of mathematics lies in mathematical thinking. "Mathematical thinking refers to the ability to use mathematical ideas and methods reasonably in the process of thinking and solving problems. Mathematical thinking is not a kind of knowledge, but a kind of ability. Mathematical thinking is the most important foundation for building the mathematical world. It plays an important role whether it is pure mathematical learning and mathematical research or applying mathematical tools to other fields. " Zhou Chuan said.

  Specifically, mathematical thinking includes logical thinking, image thinking and spatial abstract thinking. It is like the huge root system of the towering tree of mathematics. Although it is invisible from the outside, it provides an important source of nutrition for mathematics. "We often say that mathematics is beautiful, and this beauty is mainly reflected in the beauty of its thinking." Zhou Chuan said.

  The beauty of mathematical thinking lies in the balance between practicality and rationality. Zhang Jian, a math enthusiast, told reporters that taking statistics, one of the branches of mathematics, as an example, in the process of solving practical problems, statistics gives people a concise and lively aesthetic feeling. Basic statistical laws, such as the law of large numbers, the central limit law and Bayesian probability, show the harmony after the conceptual world and the perceptual world are consistent. A series of theorems behind it play an important role in the balance and unity of reason and experience, theory and practice, deduction and induction, axiomatic system and algorithm program. "The data show that some precise sciences can be developed by clear definition and logic, and some problems need to be solved by approximate measurement, which requires statistical wisdom such as error theory, probability theory and mathematical statistics." Zhang Jian said.

  The beauty of mathematical thinking lies in the beauty of "overlord" above other disciplines. According to the data, the foundation of modern science is the Elements of Geometry written by Greece 2,500 years ago. Any discipline that can be called science must have two characteristics: first, it has an axiomatic system like the Elements of Geometry; Second, the hypothesis can be verified by experiments. Physics is based on mathematics, chemistry is based on physics and biology is based on physics and chemistry. In the final analysis, all modern science is based on mathematics. "For example, in the field of artificial intelligence, all the mathematical foundations of machine learning based on neural networks are partial differential equations and linear algebra, while other schools of artificial intelligence involve probability theory and stochastic processes. Today’s artificial intelligence is difficult to leave the blessing of big data and its related statistical variables. In order to make achievements in this field, solid and advanced mathematics literacy is indispensable. " Zhang Jian said.

  Zhou Chuan believes that the beauty of mathematics lies in its profound definition, clear logic and concise result. For example, the famous Goldbach conjecture that "any even number greater than 4 can be written as the sum of two prime numbers" is concise but profound and wonderful. Hardy, a great British mathematician, once said, "Beauty is the touchstone of good mathematics, and ugly mathematics cannot last forever". Hardy’s idea is related to his advocating the artistry of mathematics, but it also reflects the mathematicians’ aesthetic pursuit of mathematical theory to some extent.

  How to have mathematical thinking

  Mathematical thinking is so important, how can we get it? Doing the problem is the first way.

  Zhou Chuan told reporters that the purpose of doing the questions is to test the mastery of knowledge, strengthen the cognitive understanding of knowledge and develop thinking. Any scientific research is a process of trial and error, and mathematical research is no exception. "When faced with a mathematical problem, we usually make bold assumptions, divergent thinking, try a variety of different ideas, and carefully deduce and prove to see which idea is feasible and beautiful." Zhou Chuan said, "Doing problems can help mathematicians deepen their knowledge understanding, develop innovative thinking and stimulate innovative ideas, which are of great benefit to scientific research."

  Zhou Chuan believes that mathematical research will not be smooth sailing. For real problems, the ideas and methods that are usually easy to think of are often not effective. This requires maintaining enough courage and perseverance in mathematical research. When encountering difficulties, we must have the courage to "open the road and meet the water" and strive to move forward until the destination, although this process may be very long.

  In addition, it is also important to read more famous mathematical books. Sunny, a math researcher, told reporters that his desk has kept classic works such as Introduction to Advanced Mathematics by Hua Luogeng, Ancient and Modern Mathematics Thoughts by Maurice Klein and Princeton Mathematics Guide all the year round. "The whimsy in these books often gives people inspiration, which makes us professional mathematics researchers shine and gain valuable innovative ideas."

  In Sunny’s eyes, most famous mathematical works are concise and to the point, which will inspire both professional researchers and staff in other fields. For example, in the third volume of the Princeton Mathematical Guide, there is a saying: "Curiosity is the driving force for doing mathematical work. When will a special result be true? Is this the best proof, or is there a more natural or beautiful proof? … … If you keep asking yourself such questions, sooner or later there will be a flash of answers — — Discover the possible path of research. " "It is tempting to think of mathematics as a collection of separate branches, such as geometry, algebra, analysis, number theory and so on. Geometry is mainly an attempt to understand ‘ Space ’ The concept of algebra is to understand the art of manipulating symbols, and analysis is to contact ‘ Infinite ’ And ‘ Continuum ’ , and so on. " Sunny said.

  How to apply mathematical thinking

  The application of mathematical thinking can be described as flexible, magical and extraordinary. Its application is more reflected in how to think and solve problems in a mathematical way.

  For example, Zhou Chuan’s current research on graph data modeling and algorithm is one of the most competitive research directions. A basic idea of this research direction is to organize, model and analyze data in the form of graphs. The reporter learned that this way of thinking can be traced back to the famous problem of the Seven Bridges in Konigsberg: In the 18th century, in the suburb of Konigsberg, East Prussia, Europe, the Pregiel River crossed the city. There are two islands in the river, and there are seven bridges between the banks and the two islands. At that time, the residents in the city discussed such a question enthusiastically: how can a walker walk from one place to all seven bridges at once without repeating, and finally return to the original starting point?

  "At first glance, this question doesn’t seem too difficult. Many people want to give it a try, but no one can find the answer. At that time, Euler, a great mathematician, thought from all the failures that such a move might not exist at all. How did Euler model and analyze this problem? " Zhou Chuan explained that, in fact, the modeling tool used by Euler is "graph". In this picture, there are 4 nodes and 7 edges. Nodes represent two banks and two islands, while edges represent bridges. Euler transformed the problem of seven bridges into the problem of finding special paths on the graph. Later, through mathematical methods, he strictly proved that such a special path did not exist, which brought a satisfactory end to the Seven Bridges problem.

  Euler’s way of thinking is a very representative thinking paradigm, which still has a strong guiding significance today. Because there are often complex relationships between data entities, modeling data organization from the perspective of graph usually leads to higher analysis and mining accuracy. "For example, in the problem of ranking the importance of web pages, web pages are usually regarded as nodes in the graph and hyperlinks as edges in the graph, and Markov process in mathematics is used to describe users’ web browsing behavior on the Internet. Under the framework of this mathematical model, the problem of ranking the importance of web pages is transformed into the problem of solving the stationary distribution of the corresponding Markov process. This transformation provides a new way of thinking and a more effective solution for the problem of ranking the importance of web pages. " Zhou Chuan said.

  "When you really experience the beauty of applying mathematical thinking to solve practical problems, you will feel ‘ Mathematics is the source of natural science ’ The discussion is really incisive. " Zhang Jian said. (Economic Daily China Economic Net reporter Liang Jianwei)

Latest! The list of the top 20 companies, such as brokerage asset management, fund accounts and fund subsidiaries, has come.

  On the evening of March 24th, China Fund Industry Association disclosed the latest ranking of the asset management of securities firms, special accounts of fund companies and special accounts of fund subsidiaries.

  With the gradual implementation of the new asset management regulations, the effect of breaking the cash pool model and curbing the channel business has appeared. The supervision of the asset management industry has continued to "prevent risks and return to the essence of investment", and the active management ability has been steadily improved, especially for securities companies. As of the fourth quarter of 2019, except for brokers with unparalleled data, the average monthly size of 19 of the top 20 brokers has all declined compared with the third quarter. At the same time, the improvement of active management ability of brokers is more obvious. In the fourth quarter of last year, six companies accounted for more than 50% of the active management scale, of which more companies accounted for more than 80% of the active management scale.

  Average monthly scale of brokerage asset management:

  oneThe scale of nine companies has declined, and this ranking has risen rapidly.

  Under the trend of shrinking asset management scale, on the whole, in the fourth quarter of last year, except for brokers with unparalleled data, the average monthly size of 19 of the top 20 brokers all declined compared with the third quarter.

  Specifically, in the fourth quarter of last year, there were six companies with an average monthly scale of 500 billion yuan, a decrease from the third quarter, namely, Guojun Asset Management, Huatai Asset Management, China Merchants Asset Management, and Securities. Among them, the average monthly scale is 1.1 trillion yuan, and it is still the only brokerage company with an average monthly scale of 1 trillion yuan. Guojun Asset Management is closely followed by 707.667 billion yuan, which is obviously different from the third place.

  Compared with the last quarter, in the fourth quarter of 2019, there were 14 brokers whose asset management decreased by more than 5%, of which 6 brokers decreased by more than 10%, with the largest decline. In the fourth quarter of last year, the average monthly scale reached 129.129 billion yuan, down 13.02% from the third quarter.

  The rankings of five companies have increased, among which the scale in the fourth quarter of last year was 140.147 billion yuan, ranking 16th, ranking four places higher, with the fastest growth rate. The six rankings have declined compared with the third quarter. Among them, the scale in the fourth quarter of last year reached 523.676 billion yuan, ranking sixth, and the ranking dropped by two places.

  The latest list, in the fourth quarter of 2019, the average monthly scale reached 140.011 billion yuan, ranking 17 th.

How long does the flu vaccine take effect? Can kidney friends play? All 10 questions are answered.

Original kidney online doctor group kidney online

Old friends who are familiar with us all know that every autumn, Kidney Online will advise kidney friends with stable conditions and poor resistance to get a flu vaccine!

Many people told us that it was because they listened to our advice that they were able to escape when colleagues and friends around them were lying down with the flu!

Influenza is more serious than the common cold, and its typical symptoms are fever, extreme fatigue, headache, body aches, cough and sore throat. → Regarding the flu vaccine, you may have many doubts, and we will answer them together.

1. Kidney disease, can you really get the flu vaccine?

Can! Many evidence-based medical guidelines suggest that patients with chronic kidney disease with stable condition should be given priority in influenza vaccination.

2. Can uremia and dialysis nephropathy patients play?

Can!

3. Can pregnant women fight?

Can!

4. What is the taboo of influenza vaccine?

The main taboo is: allergic to vaccine ingredients, resulting in adverse reactions. These people can’t be vaccinated.

And if your kidney disease is still unstable, or you are in an acute situation such as fever and cough, suspend vaccination.

5. Which vaccine is better, domestic or imported?

Use whatever you have.

6. When will you call? How long does it take to take effect?

The flu vaccine is a dozen a year, and it is best to complete the vaccination at the end of October. Inoculation is also possible now.

After 2-4 weeks of inoculation, protective antibodies began to be produced, and the protective effect lasted for about 1 year.

7. There are three prices and four prices. Which one do you want?

There are four prices, and four prices are preferred.

8. The flu vaccine we have here is said to be only cracked, so can we get it?

Sure.

"Lysis" is a method of vaccine production, which means that the lipid membrane structure of the virus is cracked and the virus "dies" more thoroughly.

9. Can you get the flu vaccine with nasal spray and kidney disease?

As we mentioned above, all patients with kidney disease can get influenza vaccine by injection, and the injection method is inactivated influenza vaccine, that is to say, the vaccine is "dead" and inactive.

If you still have a live attenuated influenza vaccine for 3-17 years old, you must pay attention to the fact that this kind of nasal spray is a live vaccine, and you must evaluate your immune status. It is not suitable for kidney friends who eat hormones, immunosuppression, kidney transplantation and other immunocompromised people.

10. Will influenza vaccination aggravate kidney disease?

Vaccination against influenza is the most effective means to prevent influenza and avoid its serious complications.

Every year, more than 60,000 people die of influenza-related respiratory diseases in China, most of whom are elderly people and people with basic chronic diseases. Therefore, our kidney friends are actually the key protection targets of the vaccine.

After vaccination, some people may have short-term slight fever, fatigue and runny nose, and generally the symptoms can disappear naturally in two or three days.

Others may see that nephropathy is usually an autoimmune disease, and vaccination will induce immune response, which will lead to immune activity and aggravate nephropathy.

However, based on the evidence of vaccination against autoimmune diseases such as lupus, rheumatoid arthritis and Sjogren’s syndrome, it is not found that influenza vaccine will significantly increase the activity of autoimmune diseases.

Presumably, this article has answered many doubts and concerns of kidney friends about influenza vaccination, and you are welcome to pass it on to your friends around you ~

Close-up ︱ Take-out "Road Grab" for 6 hours: "Fight with your life", most afraid of being complained over time.

In Ningbo, Zhejiang Province, a delivery man galloped on the way to deliver food. Oriental IC data

Wang Fanglin stared at the computer, and his eyes were less than 15 cm away from the screen.

From the time the customer places an order to the time the merchant takes an order to start catering, a new takeaway order is generated as an order to be assigned, and "wave after wave, wave after wave" floods into the computer screen.

Wang Fanglin is the captain of the Anyi Road detachment of a take-away platform in Shanghai. He assigns the order to the rider. After receiving the order, the rider will fly within a radius of 3 kilometers around the merchant, or take the meal or deliver the meal.

Between the risk of running a red light and the fines and complaints caused by overtime, riders are more worried about the latter.

On March 13th, it began to rain in Shanghai. When crossing the intersection with a green light, Zhang Ming was hit by a rider from another platform. For the rider, this kind of accident has become a habit, especially on such a rainy day.

From 11: 00 a.m. to 12: 00 a.m., the order volume surged to 264 orders, and at least 4 takeaways entered the list to be assigned every minute on average. The Anyi Road detachment began to enter a tense "explosive order" state.

In Ningbo, Zhejiang, in fast food restaurants, take-away orders keep coming out. Oriental IC data

"Did you fly there?"

"You have a new order, please deal with it in time."

When the assigned order arrives, the background will issue such a notice. Wang Fanglin turned off the speaker before the arrival of the noon peak, "it will explode when it is opened."

Wang Fanglin is the captain and dispatcher, and his team is responsible for delivering the take-away orders of some merchants within 20 blocks of hang lung plaza and Jing ‘an Museum.

Wang Fanglin stretched out during the gap. "I’m a little tired and don’t want to do it," he turned his head and told reporters. Then, a new order popped up and he continued to stare back at the screen.

The screen shows the real-time positions of 45 riders, and he needs to consider multiple factors to send orders: what is the impact of weather conditions on food delivery, will the merchants with slow food delivery slow down the orders of other merchants, and whether to assign several orders in the same direction to the same rider …

Wang Fanglin started smoking obsessively, and the stainless steel ashtray on the table was soon filled with cigarette butts.

"Consider the rider," he added. In the daily food delivery war, the rider’s work experience, familiarity with the route, ability to adapt to the road conditions, and even working attitude to deal with orders are the key factors of the war.

The 45 riders of Anyi Road detachment are divided into early, middle and late shifts, and there is also a "combat readiness group" set up to deal with more difficult and on the verge of overtime orders.

For the rider, the order is difficult.

Many orders from the same merchant sent to the same direction, the delivery distance is not long, and the delivery location is simple and easy to find. Such orders are the "toon" that riders are rushing to send; However, difficult orders, such as two orders from the same merchant, one for the east and one for the west, the complicated delivery route and the imminent overtime order, are "hot potatoes" for riders.

During the afternoon rush hour, Wang Fanglin was most annoyed to receive a call from the rider under unexpected circumstances. "Pick the bill, you don’t want to send it far away, you have everything."

The more difficult the order is, the more difficult it is for riders who don’t pick the order. Song Jun, who is divided into the "combat readiness group", is such a rare rider.

"If others can’t deliver it, pass it on to us. The dispatcher believes that you can finish it, and you don’t want to disappoint the dispatcher," said Song Jun, who has been a rider for one year.

He remembers that once in the afternoon rush hour, the captain "jammed" him with an order sent from Beijing West Road to Jiangning Road. It was two kilometers away and he had to cross eight traffic lights. The delivery time was only 10 minutes.

"When I delivered the meal to the guests, there were still 4 minutes left. Wang Fanglin said if you flew over. The guests said that I just looked at your trajectory and thought that you must overtime, but you didn’t!" He vividly described the customer’s surprise at that time.

He has been deeply impressed by the delivery, and luck without overtime accounts for a large part. "I didn’t wait for any traffic lights, it was a green light, so I went straight there."

"I’m really fighting with my life."

The rider’s meal delivery time includes the meal delivery time after the merchant takes the order. At the noon meal peak, the merchant has to take delivery and eat in the hall at the same time, which sometimes leaves the rider with harsh delivery time.

"Normally it’s 20 minutes, and some have a few minutes left." During the rush hour, Song Jun will frown and wait for us. "Merchants can’t eat, guests are rushing to eat, mobile phones open the APP, and time is also urging us."

Special food delivery software is installed on the rider’s mobile phone, which shows the customer address and delivery time of the order, and is used to receive, pick up and deliver the order. From time to time, the mobile phone sends out female voice reminders of "You have a new order" and "Your order is about to expire".

The sound is sharp and pleasant to the rider.

"If you want to make money by delivering take-out, you can deliver the orders that others don’t want to deliver. If you deliver them when others don’t want to deliver them, you will definitely make money." At Anyi Road Detachment in Jing ‘an District, the rider’s salary is calculated according to the single amount, and each order is 7 yuan.

Wang Fanglin thinks that this way of making money is fair to riders.

However, every time the rider exceeds the time limit, half of the single delivery fee will be deducted. If this leads to customer complaints and bad reviews, 20 yuan will be fined, which is close to 3 times of the delivery fee per order.

When the timeout is inevitable, the rider will confirm the delivery in advance after communicating with the customer. It’s against company regulations, but it’s the last resort to save the bill.

However, this method does not always work, and Wang Fanglin has encountered it. "I gave her the meal and said I hoped you wouldn’t complain. She said yes, I wouldn’t complain about you. After 5 pm, the complaint result came out." He was fined 1000 yuan for being complained that he had confirmed the delivery in advance, which was almost equivalent to giving it away for three days.

"I was very angry at that time, and she still told me with a smile." At that time, Wang Fanglin didn’t take long to be a rider. He lost his mobile phone and had his car stolen when delivering food. Coupled with this fine incident, he once had doubts about this business.

"You can’t complain to us over time. If you complain, there is not enough time, and the red light will definitely run, which will have a great impact on our delivery." Chu Jiaomin, a Cantonese who has delivered food for more than two years, hopes that the rider can negotiate the arrival time with the customer and consider the actual situation in the delivery process to the greatest extent.

"Sometimes the red light doesn’t matter. As long as there is no car, we basically go there," Song Jun said.

Between the risk of running a red light and the fines and complaints caused by overtime, riders are more worried about the latter. In order to seize the time, run a red light and go retrograde in violation of traffic regulations, the probability of traffic accidents naturally increases.

"Some time ago, a takeaway buddy on Xinzha Road was hit by a car and died the day before yesterday," Song Jun said with wide eyes.

Before delivery, he worked as the deputy director of the workshop in a chemical plant in Huai ‘an, his hometown. Because of a chlorine gas leakage accident, he was hospitalized for a week, and then he decided to change careers. After changing careers, he realized that the risk factor of walking on the road was not lower than that in the chemical plant. "It’s really a fight with life."

On August 23, 2017, in Guangzhou, typhoon "Tiange" brought rain, and a takeaway was riding in the rain. Vision china diagram

"Don’t worry about sending it slowly."

In the afternoon, it rained harder and it was more difficult for riders to deliver food.

When crossing the green light at the intersection of Chengdu North Road and Weihai Road, Zhang Ming met other platform riders who ran the red light. "I looked like I was going to hit it, so I had to brake."

Even people and cars slipped out a few meters away, and Zhang Ming’s knees and palms were injured. The perpetrator handed a cigarette to apologize, and Zhang Ming didn’t have any trouble for the rider who was also in a hurry to deliver food.

He can understand his peers and those who don’t seem to understand him: the security guards who don’t allow him to enter the mall in rainy days, the passers-by who accuse him of riding on the sidewalk, and the traffic police who ask him to push the cart on special sections. "They also act according to the law."

Some office buildings do not allow food delivery staff to take the passenger elevator, but only take the slower freight elevator with more floors to stay; Some office buildings don’t even allow food delivery staff to take all elevators, so riders can only climb stairs.

Wang Xu, a novice, once climbed two high floors in a row. "On a Friday rush hour, I climbed a 37th floor and a 23rd floor. After coming down, people were floating and my legs were unstable."

Although 20-year-old Zhang Ming is a novice, he is more open-minded than many old riders. Compared with his previous work in a factory, he feels that being a rider is not tiring, and he also likes the freedom of riding on the road, even if he sometimes encounters some grievances.

A meal was delivered, and the customer didn’t indicate the location. He called the customer three times before delivering it, and then received a complaint: "Too stupid, I can’t even find a way."

Sometimes grievances come from passers-by. Song Jun once took the elevator to deliver food. An old lady took the wrong elevator which only led to the high-rise area above the 16th floor. After coming in, she kept pressing the 15th floor. The takeaway brother next to her said that she would sit next door. She ignored her and the elevator "cut" and suddenly closed.

"The takeaway brother was a little impatient:’ I told you it was next door’, and the aunt gave him a white look, and the 16th floor went up, 17, 18, 19, 20, 21, 22 …", "I sweated, pressed every floor, pressed every floor, and I was really going to collapse!"

Song Jun, who still has eight orders in his hand, and the little brother looked at each other and sighed. "What a sigh, believe it or not, I pressed it for you." We dare not speak. "

Song Jun wants to work hard in Shanghai after graduating from computer school, but his father doesn’t support it. He felt that his father was always giving him a hard time: after graduating from high school, he wanted to be a soldier, but his father opposed it. After marriage, he wanted to sell electric cars, but his father still opposed it.

Until this time, Song Jun made up his mind to come to Shanghai after hearing relatives say that take-out can earn 10,000 yuan a month. Finally, he persuaded his father by sending home 5,000 yuan a month.

When Zhang Ming first earned money for his family, he was not as happy as he thought: he dropped out of school to repair his car before graduating from the second grade. After half a year, his mother didn’t praise him when he excitedly took the earned 900 yuan to his mother, even though it was the first time he earned money.

"Why didn’t you praise me? Is it too little?" He was a little confused, but he didn’t say it. After that, I entered the factory, worked as a decorator, and delivered takeout food. Every time I changed my profession, I only made more money.

When he was in the factory, he saved more than 20,000 yuan to take home for the New Year. When his mother chatted with his neighbors, he talked about the money that each other’s children gave home this year. His son’s income attracted everyone’s envy, but Zhang Ming was not so happy. "I told my mother that next time others asked, don’t say so much. I don’t like it."

Sometimes, Zhang Ming will feel "the warmth of home" from his customers. He still remembers that a boy wrote in the note of the order: "It’s raining today, so be careful, the road is too slippery, don’t worry about sending it slowly, and pay attention to safety."

"In fact, this kind of greeting is rare, and it can’t be said that everyone has it, really rare." After saying this, Zhang Ming fell silent.

"The customer is not hungry, we are hungry." 

For Song Jun, this job has brought him some "small fortunes".

He found that he can not only save money, but also become more cheerful and talkative. "Sometimes I run more orders and earn money, so I take my wife to eat mala Tang. She especially likes to eat mala Tang, and she is very satisfied every time."

Because he came to Shanghai with his wife, his clothes were cleaner than those of others in the team. Before coming to Shanghai, Song Jun didn’t want her to come, but his wife only asked, "Can you wash clothes?"

Talking about the future, he wants to save enough money and go back to his hometown to open a tea shop. He can’t wait to reunite with his two daughters.

Wang Fanglin doesn’t want to be like these people who got married early in the team. After telling the reporter about his experience of selling fruits, working as a worker in an electronic component factory and working as a waiter in a water bar over the years, he suddenly felt that "what he had done was a waste of time".

Before becoming a captain, he, like most riders, likes to watch the live broadcast on the fast hand, play the glory of the king in groups, and invite other younger brothers to drink and sing after work. Now, considering the work of dozens of people under his command, he dare not and have no time to play.

"I have exercised a lot more than before, and I have gained and lost." Wang Fanglin felt more responsibility and began to want to make some plans for the future.

Wang Xiangkun will come to Shanghai for one year tomorrow morning. He is Zhang Ming’s brother-in-law. His son is three years old and bought a Buick car in his hometown. His goal now is to buy a school district for his son. He doesn’t want his son to be a rider when he grows up.

Zhang Ming envies his brother-in-law’s car. He is saving money. In the countryside, he is old enough to get married. He needs money to marry, have children and build a new house.

Most of the members of Anyi Road detachment are like this, giving up a fairly comfortable life in their hometown in order to go back better.

When Zhang Ming sent a takeaway on the sixth floor, he climbed to the second floor "really exhausted". He remembered that he had forgotten to eat, and dragged his voice in the WeChat group of the detachment and shouted: "I am starving, and I have no energy at all."

This job is often like this, giving meals to customers, "customers are not hungry, we are hungry", Zhang Ming said.

The afternoon peak starts at 10 am and lasts until 4 pm. During this period, 45 riders delivered 938 orders.

Song Jun also reported for dinner in the group, which is the procedure for riders of Anyi Road detachment before eating-Wang Fanglin will stop sending orders to them in the background after receiving the report.

As the volume slowly declined, Wang Fanglin got up slowly and left the computer desk with a slightly narrow space. "I feel dizzy and a little nauseous," he described the feeling when I left my seat.

At this time, he finally had time to open the already cool takeaway box lunch.

As the year is approaching, have you figured out all these problems concerning the money bag?

CCTV News:The Chinese New Year is coming, and the topic of "thirteen salaries" is getting hotter and hotter. What exactly is "thirteen salaries"? What’s the difference with the "year-end award"? Can everyone get it? What else should we pay attention to about the money bag? 

Is "Thirteen Salaries" and Year-end Awards the same thing?

"Thirteen salaries" means the thirteenth monthly salary, also known as "double salary at the end of the year", which means that the unit pays one more month’s salary to the individual according to the prescribed procedures.

In the 1980s, foreign-funded enterprises had more autonomy in the distribution of wages, and the policy allowed these enterprises to pay one month’s salary at the end of the year instead of paying various kinds of meals and transportation subsidies to state-owned enterprises. In this sense, thirteen salaries more reflect the comprehensive distribution of various subsidies.

Now, with the national reform of enterprise wage distribution, some domestic-funded enterprises have also borrowed the method of thirteen salaries. In this sense, the thirteen salaries of many enterprises have a certain year-end reward nature.

The year-end bonus refers to the one-time bonus paid to employees by withholding agents such as administrative organs, enterprises and institutions according to their annual economic benefits and comprehensive assessment of employees’ annual work performance.

The difference between the two is that "thirteen salaries" can better reflect the fairness of incentives; The year-end bonus can better reflect the results of performance appraisal. 

Are there as many "thirteen salaries" as year-end bonuses?

In the absence of specific provisions, there is a slight difference in the calculation base between the two: the year-end award has certain uncertainty in the calculation amount.

For the calculation base of "thirteen salaries", if the employer has clear regulations, it will be implemented in accordance with the regulations; If the employer does not clearly stipulate, the judicial practice tends to use the average wage of workers in the current year as the calculation base; For those who should pay thirteen salaries when the labor contract is terminated in the middle of the year, the judicial practice tends to take the average salary of workers for 12 months before the termination as the calculation base of thirteen salaries.

How to pay "thirteen salaries"?

Like the year-end bonus, the laws and regulations do not make specific provisions on the employer’s payment of "thirteen salaries", which belongs to the category of independent management of enterprises, and the company can consider whether and how to pay according to its own situation.

If there is no explicit stipulation in the enterprise and there is no practice before, the workers cannot force the unit to pay double salary at the end of the year. The standard of the thirteenth month’s salary is basic salary or full salary or bonus, which is completely determined according to the agreement between the enterprise and employees or the provisions of the enterprise’s salary and welfare policy.

Therefore,Different enterprises have different regulations on the payment of "thirteen salaries".Some enterprises stipulate in the Employee Handbook that at the end of the Lunar New Year, the company will give employees one month’s salary as a bonus, and the bonus will be calculated in proportion to the employees who joined the company that year and passed the probation period before December 31. Employees with poor attendance, poor performance or violation of discipline cannot get this bonus. 

Can you send it or not only depends on the boss’s mood?

Some enterprises stipulate that employees must meet many conditions in order to get double pay at the end of the year:

Employees must have served in the company for three months in the current year; You must still work in the company on the day of double pay; Employees who resign or terminate the labor contract through negligence or non-negligence before the double pay date will not be entitled to the annual double pay … …

With so many conditions, does it mean that whether the "thirteen salaries" and the year-end bonus are issued depends on whether the boss is happy or not?As a matter of fact, thirteen salaries and year-end bonus are all components of wages, and employers cannot violate labor laws and regulations in the process of issuing thirteen salaries and year-end bonus.The Labor Contract Law stipulates that the labor remuneration must be clearly defined in the terms of the labor contract. Therefore, if workers want to protect their right to get "thirteen salaries" or year-end bonus at the end of the year, they must make clear the relevant rules and regulations of the unit in advance and be familiar with the labor contract.

If the labor contract or unit rules and regulations stipulate the amount or calculation method of "thirteen salaries" or year-end bonus, and the laborer has paid the labor, the unit should pay it in full according to the regulations.

Can employees who leave early and are new get it that year?

If the year-end bonus is not clearly stipulated in the labor contract or the company’s rules and regulations, according to the principle of equal pay for equal work, the labor dispute arbitration institution or court will generally support the resigned employees to get a certain percentage of the year-end bonus.

Like former employees, if the company’s rules and regulations and labor contracts do not clearly stipulate the year-end bonus, according to the principle of equal pay for equal work, labor dispute arbitration institutions or courts will generally support "new employees" to get a certain percentage of the year-end bonus.

Will the integral be cleared if it is not used?

At the end of the year, it is also the peak period of forwarding information similar to "points need not be cleared". It is understood that several major operators do have the system of clearing points, but it is best to log in to operator official website for details.

Credit card points

It’s not just the phone bill. For some credit card holders, the amount of credit card swiping is tens of thousands of yuan every year, but they have never exchanged points for gifts. Some people think that the points in bank cards are permanently valid, but in fact, the validity period of credit card points in different banks is different, and there are great differences.

More complicated than the deadline is the value of the integral. Points used to be a sword for banks to promote credit cards, but with the increasing popularity of credit cards, points are becoming less and less valuable. Generally speaking, for every dollar spent by swiping a card, a point will be generated. Official website, a credit card center of a bank, shows that gifts can hardly be exchanged under 10,000 points, while 50,000 points can be exchanged for a pillow with tens of dollars, while it takes 3.87 million points to exchange an Apple 6 mobile phone.

Consumption membership card points

In order to attract consumers’ secondary consumption, many shopping malls and supermarkets generally adopt the integral membership card system. However, in order not to lose points in vain, many people seem to be redeeming points, but in fact they are busy spending money at the end of the year, especially women.

Remind consumers not to spend blindly just to use points. In addition, unlike communication operators and bank credit cards, the points of shopping malls and supermarkets are generally one year. As merchants have the final right to interpret points redemption, the ways to inform users are different, reminding consumers to check in time to avoid missing them.

Reminder: There is a trap in the redemption of points at the end of the year!

The mobile phone receives a short message from the bank, and the points are exchanged for cash packages. Click to fill in the relevant information, and the funds in the card will be stolen. Police reminder: When you receive similar messages, you must be more careful, especially to remind you of points redemption and other information. You must be more screened and verified by official telephone and official website. 

Pay attention to redeeming points at the end of the year

① Look for the official Internet websites, mobile phone websites and credit card points of major banks to exchange for official websites, and be wary of logging in by searching for websites or clicking on links provided by others;

② When redeeming points, please pay attention to checking the points information in the SMS verification code for redeeming points. There will be no "virtual deduction" when the bank points are exchanged. If the message is prompted as payment information, please be highly vigilant;

3 Bank staff will not ask cardholders for sensitive information such as dynamic verification codes and passwords of credit cards, and do not disclose them. Any request is fraud;

(4) If you have any questions about the received 95533, 95588, 10086 and other related short messages, it is suggested that you don’t do anything for the time being, and consult the staff of banks, telecommunications and other outlets as soon as possible; 

⑤ It is suggested to install security software (such as Tencent Manager) on mobile phones to screen fraudulent short messages and identify phishing websites, and pay attention to upgrading the software regularly;

⑥ Once you click the link, you find that the mobile phone can’t receive short messages, and the phone or card is stolen. You should immediately reinstall the mobile phone system, restore the factory settings or use anti-virus software to kill viruses. At the same time, it is necessary to freeze all third-party accounts and online banking in mobile phones at the first time, and inform relatives and friends in the address book, delete short messages in time, and do not click on links to avoid expanding risk losses.

⑦ Don’t click on unknown links, pictures and files!
