On the morning of June 30th, Shanghai Fengxian coastal marine ecological protection and restoration project started smoothly. This project is another marine ecological protection and restoration project supported by the central government in Shanghai after the implementation of the coastal marine ecological protection and restoration project in Shanghai in 2022, and will be completed by the end of 2024.

　　General layout of the project. The pictures in this article are provided by Shanghai Water Affairs Bureau.

　　The Paper learned from the Shanghai Water Affairs Bureau that the project starts from China and Hong Kong in Fengxian District in the east and reaches Huadian Ash Dam in the west, and the layout of the project is "one corridor and three districts". "One Corridor" refers to building a 17.4-kilometer coastal ecological corridor, relying on coastal ecological restoration, forming land-sea linkage and creating an open strip-shaped coastal composite ecological space; "Three areas" refers to the construction of multiple ecological service function integration area, middle and high beach habitat protection demonstration area and natural succession habitat area along the coastline from east to west, giving full play to the ecological service functions of each area, creating a bright spot for the restoration of coastal wetlands in Shanghai, and continuously improving the diversity and stability of coastal ecosystems.

　　Multi-ecological service function integration area (renderings)

　　It is understood that the main project indicators include 51.97 hectares of Spartina alterniflora ecological control, 4,115 meters of tidal ditch system restoration, 69 hectares of native salt marsh vegetation restoration and 6,438 meters of wave dam restoration; A total of 45 hectares of reef habitats have been built, and the ecological transformation of seawalls is 4.5 kilometers; A new coastal ecological monitoring and research station will be built, three ecosystem buoys will be deployed, a carbon flux tower will be built, ecological environment tracking and monitoring will be carried out, and supporting facilities such as popular science signs and scientific research stations will be arranged.

　　"The ecological control project of Spartina alterniflora can solve the ecological problem of serious invasion of Spartina alterniflora in the project area, and the restoration of salt marsh vegetation communities such as reeds and sea bream can further improve the habitat quality of salt marsh wetlands." Yang Dongyan, the second bid construction unit of Shanghai Fengxian Coastal Marine Ecological Protection and Restoration Project and Fengxian Project Manager of China Communications Shanghai Airlines Co., Ltd., said that the coastal zone is an important support for the green development of the city and an important barrier against natural disasters such as storm surges at sea. It plays multiple functions in biodiversity protection, shore protection and beach protection, carbon sequestration and foreign exchange enhancement.

　　At the same time, the ecological problems of serious beach erosion and low health of marine biological community in the project area are solved by implementing the in-situ restoration of wave dam and the construction project of reef habitat with both ecological function and disaster reduction function. By carrying out the ecological reconstruction project of seawall, the ecological problems of blocked habitat connection inside and outside the seawall and poor land-sea coordination in the project area are solved.

In 2024, which new energy brand performed most unexpectedly? For many consumers, this answer is not asking the world, nor BYD, but Xiaomi. The first model of Xiaomi Automobile has been on the market for half a year, and the cumulative delivery has exceeded 100,000 vehicles, and it is possible to sprint 130,000 vehicles throughout the year.

However, it is obviously impossible to rely on this car alone. Xiaomi needs to continuously expand its product lineup. Recently, Xiaomi Auto officially released the official map of Xiaomi YU7, and the pictures of the real car have also appeared in the declaration catalogue of the Ministry of Industry and Information Technology. So what about this car?

What kind of car is Xiaomi YU7?

The performance of Xiaomi SU7 is obvious to all, which proves that Xiaomi does have the ability to create an explosive model. Then, as the second model of Xiaomi Automobile, what kind of car is Xiaomi YU7?

As can be seen from the official map, Xiaomi YU7 is an SUV. According to market rumors, the car’s body length is close to 5 meters and the wheelbase is 3 meters. It is a medium and large SUV. The launch of such a model proves that Xiaomi Automobile is still confident in its own strength.

It’s not surprising that Xiaomi chose SUV for the second car. After the success of the first model, it needs to find another model with a relatively large market capacity and can enhance the brand image, and SUV is preferred by both young people and home users. It is logical to launch SUV.

As soon as Xiaomi came up, he directly launched medium and large SUVs for many reasons. First of all, after the success of Xiaomi SU7 in the first battle, the brand image of Xiaomi Automobile has greatly improved, and it is time to hit the higher-end market; Secondly, choosing a medium and large SUV can also avoid entanglement with too many competitors in the compact and medium-sized SUV market, which is more suitable for Xiaomi, a small manufacturer who takes the boutique route.

In terms of appearance, the new car adopts the family style established by Xiaomi SU7, and the closed front face with personalized headlights looks more imposing. It is worth mentioning that, as can be seen from the official website, the shape of this car is still relatively conventional, and there is no slip-back body, but the muscle lines on the side of the car body are still attractive.

Coming to the rear of the car, the new car is slightly different from Xiaomi SU7, but both of them use large-size semi-enclosed light strips, and the recognition is still relatively high. However, compared with cars, the rear of Xiaomi YU7 looks more stable, which proves that Xiaomi also wants to attract more family consumers after gaining a foothold.

In terms of size, according to the application information of the Ministry of Industry and Information Technology, Xiaomi YU7 has a body length of 4999mm, a car width of 1996mm and a wheelbase of 3,000 mm. It adopts a five-seat layout, and will also provide 19-inch, 20-inch and 21-inch wheels.

In terms of power, Xiaomi YU7 is a pure electric vehicle. It is expected to be equipped with a dual-motor system. The maximum power of the front motor is 220kW, and the maximum power of the rear motor is 288kW. At the same time, it will be equipped with a battery pack of Sanyuan Li. However, so far, the specific power information and cruising range of this car have not been announced.

Some conjectures about Xiaomi YU7

So far, apart from the application information of the Ministry of Industry and Information Technology, Xiaomi YU7 doesn’t have much exact information, but this car has the blessing of Xiaomi’s strong marketing ability, so the degree of attention is very high. Let’s guess, what actions may it take?

First, the time to market. Now it is the end of 2024. With the successful experience of Xiaomi SU7, the speed of product launch will be greatly improved. Without any accident, Xiaomi YU7 may be pre-sold at a large auto show in April 2025, and then officially listed around June. Therefore, people who want to buy this car will not wait too long.

Secondly, the selling price. At present, Xiaomi Auto has not given the price range of Xiaomi YU7, but it is a pure electric medium and large SUV. In order to establish a high-end image, the pricing may be much higher than that of Xiaomi SU7 currently on sale. The starting price of Xiaomi SU7 is 215,900 yuan, so the starting price of Xiaomi YU7 may be more than 250,000 yuan.

According to Xiaomi’s long-standing habit, this car will be promoted according to the level of 300,000+in the early publicity stage, and then a relatively close price will be given to attract more consumers.

The rest is the intelligent cockpit and intelligent driving. In terms of intelligent cockpit, Xiaomi is quite competitive. The cockpit of Xiaomi YU7 will be smarter than Xiaomi SU7, and the use experience will be better. In terms of intelligent driving, Xiaomi’s technology accumulation is relatively general, and it is expected that there will be no major breakthrough, but it will also be upgraded on the existing basis, so as to reach the first-class level of the same class and meet the daily needs of users.

Who are the competitors?

According to the previously officially released pictures, the reason for the naming of Xiaomi YU7 is: Y Ultra, which is stronger. However, Model Y is a medium-sized SUV, while Xiaomi YU7 is a medium-sized SUV with a body close to 5 meters, so there is not much intersection between the two cars.

As far as the current situation is concerned, Xiaomi YU7′ s competitors are mainly domestic pure electric new energy vehicles, and the representative ones are HarmonyOS Zhixing’s and, both of them are medium and large SUVs, all of which adopt pure electric power systems, and the price range is close to Xiaomi YU7, so they belong to direct competitors.

After the listing of Xiaomi YU7, it is expected to rewrite the market structure of domestic pure electric medium and large SUVs. From an objective point of view, this market is not easy to do, there are almost no explosive models, and many models even turn to dual-power systems, no longer focusing on pure electricity. For Xiaomi YU7, this is both an opportunity and a challenge. Pure electric system is not very popular in the high-end market, but if Xiaomi YU7 can make a breakthrough, Xiaomi’s automobile business will reach a new level.

Summary:The progress of Xiaomi Automobile has exceeded many people’s expectations, and for this reason, people have more expectations for Xiaomi YU7. Relying on China’s powerful and perfect new energy supply chain, Xiaomi should not disappoint consumers, but it will also face many challenges. So, do you think this car can be successful?

Nowadays, more and more people eat nutritional supplements (health food). According to a survey of more than 36,000 people conducted by the Nutrition Society of China in 2017, 30.50% of adult residents have bought nutrient supplement products, 54.85% have eaten them, and the consumption rate of the elderly is even higher. At the same time, there are also many criticisms that eating nutrient supplements is ineffective and even harmful to health. So, should nutrient supplements be eaten and how should they be eaten?

01

Nutrient supplements are available, but they should not be abused.

Generally speaking, there are two main ways to solve the problem of nutritional deficiency. One way is to balance the diet, that is, to match the variety and quantity of the daily diet according to the recommendations of the Dietary Guidelines for China Residents 2022, which is the fundamental method applicable to all people. Another way is to eat nutrient supplements and fortified foods, which are suitable for people whose daily diet is not balanced enough, as well as pregnant women, nursing mothers, infants, the elderly and other special groups with high demand for certain nutrients, as well as people who have low sunshine, high-intensity exercise and physical activity, and live in special environments such as high temperature, low temperature and plateau or have specific occupations. In addition, for individuals with nutrient deficiency, it is a simple and effective method to use nutrient supplements (and at the same time, they should actively improve their diet). In short, nutritional supplements are neither a panacea nor a scourge, but one of the effective means to solve nutritional problems, provided, of course, that they are supplemented appropriately and reasonably. Nutritional supplements are necessary and beneficial for some people who cannot adhere to a balanced diet or have special nutritional needs.

At present, the use of nutrient supplements is roughly in three situations:

First, it must be supplemented, such as folic acid supplementation during pregnancy and pregnancy, vitamin D supplementation for infants, and universal iodine supplementation (iodized salt);

The second is to supplement dietary deficiency or to meet special needs, such as DHA for those with insufficient fish and shrimp intake, vitamin D for those with insufficient sun exposure, vitamin B12 for the elderly, dietary fiber for those with constipation, and protein powder for those who need a high-protein diet.

The third is abuse, no targeted supplement, follow the trend, or blindly increase the variety or dosage. These three situations are very common around us.

If anyone decides to use nutritional supplements, they should first follow the advice of relevant medical guidelines or expert consensus, and don’t abuse them blindly; Secondly, we should be targeted, make up for what is missing, make up for what is missing, and don’t overdo it. It is best to consult nutrition-related professionals, such as nutritionists, health managers or doctors.

Nutrient supplements suitable for middle-aged and elderly people

Different from infants, children and pregnant women, middle-aged and elderly people are often accompanied by metabolic problems such as hyperglycemia, hyperlipidemia, hypertension, hyperuricemia, hyperhomocysteinemia and osteoporosis. These specific problems should be fully considered in both daily diet and nutrient supplements.

With the aging of population, osteoporosis has become an important public health problem in China. The prevalence rate of osteoporosis in the population over 50 years old in China is 20.7% for women and 14.4% for men. The prevalence of osteoporosis in people over 60 years old has increased significantly, especially in women. From the perspective of preventing osteoporosis, middle-aged and elderly people should first ensure calcium intake. The recommended daily intake of calcium for adults is 800 mg, and that for people aged 50 and over is 1000 mg. We should take enough calcium through diet as much as possible, take 300 ml of milk or a considerable amount of dairy products every day, often eat soy products, and eat calcium-rich foods such as green leafy vegetables every day. When calcium intake in the diet is insufficient, calcium agents can be given to supplement it. The selection of calcium agent should consider its calcium content, safety and effectiveness. Calcium carbonate has high calcium content and high absorption rate, and is easily soluble in gastric acid. The common adverse reactions are stomach discomfort and constipation.

For bone health, vitamin D may be more important than calcium, because vitamin D can promote the absorption of intestinal calcium, promote bone mineralization, maintain muscle strength, improve balance and reduce the risk of falling. Vitamin D is mainly synthesized by skin under sunlight (ultraviolet rays). People with insufficient sunlight should pay attention to vitamin D supplementation, with 400-600 international units per day for ordinary adults and 600-800 international units for the elderly aged 65 and over. With the social and economic development and lifestyle changes, especially the reduction of outdoor living and working hours, vitamin D deficiency has become a global public health problem. Epidemiological data show that vitamin D deficiency is common in Chinese population.

Vitamin D supplementation for the elderly is also helpful to prevent and treat muscle attenuation syndrome. Serum 25- hydroxyvitamin D3 of the elderly can be detected first. If it is lower than 30 ng/ml (75 nm/l), vitamin D should be supplemented, and 600-800 international units should be supplemented every day. Adequate intake of protein is more important for the prevention and treatment of muscular dystrophy syndrome. The recommended daily intake of protein for the elderly should be maintained at 1.0 ~ 1.5g/kg (body weight) and evenly distributed among three meals a day. In addition to high-protein foods such as milk, eggs, meat, fish and shrimp, supplementing whey protein is more beneficial to prevent muscle attenuation syndrome. In addition, the elderly suffering from muscular attenuation syndrome should be properly supplemented with nutritional supplements containing a variety of antioxidant nutrients (vitamin C, vitamin E, carotenoids, selenium).

There is also a nutrient that is closely related to the joint health of the elderly. It is glucosamine, referred to as "glucosamine", which is the main component of cartilage tissue. According to the recommendation of China Nutrition Society, for adults with joint movement injury or osteoarthritis, 1000 mg of glucosamine or 1500 mg of glucosamine sulfate/glucosamine hydrochloride should be supplemented every day.

Anemia is also common in the elderly. The survey shows that the prevalence rate of anemia in the elderly over 60 years old is 12.6%. This is related to the weakened digestive function of the elderly and the decreased absorption rate of nutrients such as iron and vitamin B12. The elderly should pay attention to the detection of blood routine (including hemoglobin). If hemoglobin is found to be lower than normal and diagnosed as iron deficiency anemia, they should take iron (according to doctor’s advice). Vitamin C supplementation can promote iron absorption and help prevent iron deficiency anemia.

The effective component of fish oil is DHA, which is an ω-3 polyunsaturated fatty acid, which is beneficial to the nervous system and blood lipid metabolism of middle-aged and elderly people. High-purity fish oil can reduce triglyceride in blood by 30%~40%, with little adverse reaction and good tolerance. Low dose of omega-3 polyunsaturated fatty acids has weak lipid-lowering effect and only plays an auxiliary role. In addition, supplementing fish oil or ingesting fish rich in DHA is also helpful for the elderly who have lost muscle mass and weakened muscle function.

In addition, there are more and more clinical applications of (whey) protein powder, including patients before and after operation, severe patients, tumor radiotherapy and chemotherapy, burn patients, patients with infectious diseases, patients with wasting diseases, and elderly patients with muscle decline, all of whom advocate increasing protein supply or adopting a high-protein diet (except for patients with renal insufficiency and hepatic coma, please follow the doctor’s advice).

Nutritional supplements suitable for vegetarians.

Vegetarians lack animal foods in their diets. If we don’t pay special attention to food collocation, we will easily lack protein, vitamin B12, iron, zinc and omega-3 polyunsaturated fatty acids. Vegetarians can refer to the recommendations of the healthy vegetarian model introduced later to match their diets. If the diet cannot meet the requirements of the healthy vegetarian model, they should consider supplementing protein, fish oil (omega-3 unsaturated fatty acids, DHA) and multivitamins and minerals containing iron, zinc and vitamin B12.

Nutritional supplements suitable for dieters to lose weight.

All kinds of weight loss methods require direct or disguised reduction of energy intake, such as only 1200 kcal (female) or 1400 kcal (male) per day, and an average reduction of 500 kcal per day. It is often difficult for a diet to provide comprehensive and sufficient nutrients when the food intake or food types are obviously limited. At this time, you can consider supplementing multivitamins and minerals. Proper supplementation of vitamins and minerals during dieting and weight loss can not only avoid nutrient deficiency, but also avoid the effect of weight loss due to the lack of certain vitamins (such as vitamin D), minerals (such as calcium) and probiotics.

Most diets reduce energy intake (carbohydrate and fat) while ensuring protein’s intake. The high-protein (low-carbon) diet also advocates increasing protein’s intake. Supplementing protein is also a common practice of dieting and losing weight.

The key to selecting nutrient supplement products

When you decide to choose a nutrient supplement, you should first choose a targeted type and appropriate dosage. The types and dosage of nutrient supplements have been mentioned above. Nutrient supplements are definitely not the more the better, the more complete the better, and you can’t choose or add them at will. If you don’t know what kind or dosage you should choose, you should consult a dietitian, health manager or doctor and follow their instructions.

In China, nutrient supplements are managed as health food, and there should be a special "police tactical unit" logo on the label of nutrient supplements that meet the requirements of health food. It is suggested that the nutrient supplement marked with "police tactical unit" should be the first choice. In addition, it is more important to choose a big brand. A good product formula is designed reasonably (in line with the needs of the corresponding population), and the types and quantities of nutrients are true and reliable, and there is no exaggeration in publicity. All nutrient supplement products should be treated with caution. If you can read the ingredient list and label, buyers or consumers should know their ingredients and attributes, avoid blind intake, and don’t be misled by product advertising. Nutrient supplements are food, not medicine, and cannot treat diseases. All nutrient supplement foods (except drugs) that claim to be able to treat diseases are suspected of violating regulations or false propaganda.

In a word, people should give priority to get all kinds of nutrients from the diet, and the body’s needs for nutrients can be met through reasonable dietary collocation. When the diet can’t meet the needs of nutrients, we can choose appropriate nutrient supplements according to our own physiological characteristics and real needs.

In the past, listening to songs required buying tapes, CDs and playing equipment. Later, MP3 format appeared, so the collection of hundreds of songs in the computer was random, but it needed to be searched everywhere.

Later, with the popularity of smart phones, it is very convenient to install a music application in mobile phones to easily "own" a large number of songs and listen to them whenever you want. With the strengthening of copyright protection, you used to be able to listen to all the songs in one music application, but now you need to switch between several music applications, which music application do you use?

CCTV News:Ma Zhongyu, the detachment leader of the Criminal Investigation Detachment of Tongliao Public Security Bureau, Inner Mongolia, is a 38-year-old policeman. Since the launch of the special campaign to eliminate evils in 2018, Ma Zhongyu has been in the front line of the town, leading his brothers to fight for several months, and successively cracked down on "3 06" Liu Moumou, "7 20" Xue Moumou, "8 25" Dong Moumou and other black-related projects, arresting 137 suspects involved and collecting more than 400 clues.

And these outstanding achievements are very common to him. During his 38 years as a policeman, he has investigated more than 6,700 important cases, which is equivalent to solving one case every two days, and there is no wrong case, so he has become a well-deserved "criminal investigation expert".

The "technical flow" criminal police who love to study.

Being a criminal policeman has been Ma Zhongyu’s dream since he was a teenager, so he did not hesitate to choose Inner Mongolia Police Academy when he applied for the university. After graduation, he was assigned to the Criminal Investigation Detachment of Tongliao Public Security Bureau, Inner Mongolia, and he became a criminal policeman who served justice and eliminated violence.

When he first arrived at the criminal police team, he followed the experienced masters in the team, not afraid of hardship and fatigue, learning bit by bit and accumulating bit by bit. This hard work made the masters willing to take him with them when they went to the police. Soon, he emerged with excellent on-site investigation ability and meticulous on-site reasoning logic.

In 1984, Ma Zhongyu took the lead in the investigation. From then on, he got into the habit of taking case notes. Today, hundreds of Yu Ben case notes are piled up in his desk and bookcase, each of which is filled with every case introduction, case analysis, trace material evidence at the crime scene, description of criminals and summary thinking. He also wrote 21 papers and published them in journals at all levels. "These notes are like a database, which has helped me solve one major and difficult case after another."

Ma Zhongyu and colleagues study physical evidence.

On July 23, 1989, major thefts occurred in the production and operation department of Huolinhe mining area and the oil company of Huolinguole city successively. Fingerprints were extracted from the scene of the two cases and identified as the same person. On June 5, 1990, investigators discovered other criminal facts of Renguomoumou in Lubei Town, Zhalute Banner, and extracted his ten-finger fingerprints. Because the suspect destroyed all the fingerprint lines of his ten fingers in order to cover up his criminal facts, it could not be identified normally. Ma Zhongyu studied and analyzed the fingerprints of the scene and the fingerprints destroyed by the suspect, found out the regular characteristics of the change characteristics, and explained the differences by theoretical science, thus reaching the same conclusion. In the face of the evidence, the criminal suspect who has been tried for four months, but refused to explain the facts of the crime because he thought his fingerprints were destroyed and could not be identified, finally bowed his head. After closing the case, he wrote the paper "Polar Analysis of Fingerprint Identification", which provided valuable detection experience for colleagues.

On January 21, 1995, in the case of Lu’s murder in Shebotu Town, Kezuozhong Banner, Ma Zhongyu explored the "Experimental Study on Using 502 Adhesive to Show Handprints" during the detection, and used this technology to extract several fingerprints of the suspect from the scene, and directly compared the cracked cases.

His experience and technology also played an important role in the detection work of his peers. In December 1992, a murder case occurred in Kulun Banner, Tongliao City. The victim was strangled to death by the criminal suspect. In order to find more traces of criminal suspects, the criminal investigation technicians in Hure Banner successfully extracted a broken fingerprint by using the technical method of "Fingerprint Extraction from Human Skin with Filter Paper 502" summarized by Ma Zhongyu in practice. After visiting and touching the suspects, they found the same and quickly cracked the case.

Vow to solve the case for the people to the end

When people look at public security, the key is to solve the case. "I can’t solve the case, and there is a sense of guilt for the people. I am worried and sleepless." In Ma Zhongyu’s eyes, as long as there are cases related to ordinary people, there is no distinction between major cases and minor cases.

In order to solve the case as soon as possible, he didn’t sleep for 72 hours, visited and investigated in the countryside for 48 days, and ate and lived in the office for 192 days … … "Doing criminal investigation is not bitter, but it is also fun." Ma Zhongyu thinks that solving a case is like walking a maze. If you go one way and find there is no way, you will come back and take another one, and so on until you find the right one.

Ma Zhongyu is at work

On November 16, 1995, Zhao Moumou, an accountant of the Planning Commission of Holingol City, Tongliao City, and his niece were killed in their father’s home, which triggered various speculations among the masses. Ma Zhongyu rushed to the scene of the crime overnight, unable to attend to the pain of motion sickness and rest, and immediately went into exploration work. Repeatedly, upstairs and downstairs, I didn’t find any valuable clues.

"People can’t fly, it’s impossible!" Ma Zhong squatted on the ground and repeatedly explored. If it didn’t work once, it would come again for the second and third time … … At the end of the day, I finally found a three-dimensional footprint outdoors and a looming dust footprint indoors. After analysis, the two footprints were identified as the same, and then the suspect’s footprint was determined, and the detection of the case made important progress.

Subsequently, Ma Zhongyu found that Li’s footprint was the same as the scene after a comprehensive arrangement and key examination, and was further identified as the same type of footprint by comparison. Later, Ma Zhongyu put forward a series of measures in time, such as finding blood clothes, conducting blood type tests, comparing the remnants (buttons) on the scene, and tracking them. Finally, he found the coat that Li was wearing when he committed the crime in the laundry, and successfully tested the blood samples on the clothes and the missing buttons, which made the case cracked in one fell swoop.

On June 17th, 2016, 10 days after Wang, a nurse in a hospital in Tongliao, lost contact with his family, his body was found by the police under the dam of Liu Yin Road in the development zone. The golden period of murder detection has been missed, and the case detection is deadlocked. In this race against time, Ma Zhongyu is on the verge of death. As a core member of the "June 17" project headquarters, Ma Zhongyu stayed up all night, and went to Yu Sheng for cross-provincial investigation, and visited the whole city, and got a lot of evidence clues. On December 23, the task force received a work request from Liaoning police to verify Xu, a suspect in the robbery and murder case. Because the characteristics of the suspect are highly consistent with the investigation clues and criminal means analysis of the task force, Ma Zhongyu is keenly aware that this may be a breakthrough in the "6 17" case. He immediately organized personnel to investigate around Xu, and extracted the material evidence information of Xu’s family and conducted key tests in time. After 192 days of investigation and fighting, finally, Xu confessed the criminal facts of killing Wang and three other homicide cases in Tongliao City on the evening of June 17, 2016. So far, the "6 17" series of rape, robbery and murder cases have been successfully solved.

In the eyes of leaders and colleagues, as long as there is Ma Zhongyu, there is no case that cannot be taken. This kind of confidence comes from Ma Zhongyu’s grasp, combing and analysis of the case and his relentless pursuit to find out the truth. It also comes from the fact that he has people in his heart. It is precisely because of this deep affection of "taking the hearts of the people as the heart" that he has made extraordinary achievements in ordinary posts. He has been appraised and hired by the Ministry of Public Security and the Public Security Department of the Autonomous Region as a senior engineer of national physical evidence appraisal, a criminal technical expert of public security in the Autonomous Region, and a special investigator. He has won the National "Top 100 Interpol" and won the first class merit and the second class merit twice. (Source: Ministry of Public Security)

　　If you talk about pure electric vehicles, everyone will definitely think of Tesla, but if you talk about hybrid models, I’m afraid you can’t bypass Toyota. There is a folk saying: "There are only two kinds of hybrids in the world, one is Toyota hybrid, and the other is other hybrids."Although this is somewhat exaggerated, it is enough to illustrate Toyota’s advantages in hybrid technology and its reputation in the hearts of consumers. Recently, GAC Toyota’s 60-minute dual-engine hybrid endurance race (hereinafter referred to as endurance race) kicked off in Shanghai. Can fuel consumption and speed be taken into account when running the track with hybrid models?

　　Before the start of the endurance race, let’s briefly review Toyota’s hybrid system, which is called THS(Toyota Hybrid System) and first appeared in 1997.

　　In 1997, the first generation Prius, code-named XW10, came out. It was equipped with the first generation THS hybrid system, and it was the first mass-produced hybrid electric vehicle in the world. The first generation THS system mainly consists of a 1.5L engine, a hybrid drive axle, a Power Control Unit (PCU) and a power battery pack. The sales volume of the first-generation Prius is not high, but it pioneered the hybrid electric vehicle for Toyota and even the whole automobile industry.

　　In 2003, the Prius ushered in a new generation, and the second-generation Prius code-named XW20 appeared. At the same time, its hybrid power system has been upgraded from THS to THS ⅱ, and the engine, motor, battery pack and other components have been improved. At that time, the situation in the Middle East was tense, and the international oil price continued to rise. Therefore, the second-generation Prius with a comprehensive fuel consumption of only 5.2L per 100 kilometers received great attention. In addition to winning the prize, the second-generation Prius has also achieved great success in sales.

　　In 2009, Toyota released the third generation Prius, and its hybrid system also ushered in a major upgrade. A 1.8L Atkinson cycle engine with thermal efficiency as high as 38.5% replaced the previous 1.5L engine. At the same time, the transmission between the power splitting device and the reduction mechanism is changed from chain transmission to gear transmission, and the structure is more compact. The third-generation Prius was a great success, with sales exceeding 1 million vehicles in two years.

　　In 2015, Toyota released the fourth generation Prius at the Frankfurt Motor Show. The biggest change of this generation of hybrid system is that the structure of the hybrid drive axle has changed. In the previous hybrid system, the driving motor and the generator were arranged coaxially on the left and right sides of the planetary gear device respectively; In the new hybrid system, the driving motor is moved to the other side of the planetary gear device, arranged in parallel with the generator, and connected with the reduction mechanism through the balance shaft gear. This change makes the hybrid drive axle more compact, and the length is shortened from the previous 409mm to 362 mm. At the same time, due to the reduction of the number of parts, the mechanical loss is also reduced by 20%.

　　In addition to Toyota’s hybrid system, Honda’s i-MMD hybrid system is also widely sold in China. Although they are all hybrid systems, their driving logic is essentially different. The former connects the engine and two motors through the planetary gear mechanism and works in harmony. Honda’s i-MMD hybrid system has no planetary gear mechanism, which uses electricity at low speed and starts the engine to charge when the power is low; The engine will directly drive the vehicle at high speed.

　　This endurance race includes all hybrid models of GAC Toyota — — The positioning of the three models is different, and they are also very representative in terms of power system.　　

Practitioners say

The Spring Festival, the most weighty traditional festival, is emitting a new "flavor of the year" with the iteration of the Internet.

With the opening of CCTV Spring Festival Evening, "Li Sisi’s Mouth Red Number" and "Zhang Xiaofei’s" I don’t know the color "coat" were all posted on the hot search in the form of pictures, texts and short videos. According to the data of e-commerce platform, Zhang Xiaofei’s expensive coats have been sold out within 10 minutes.

The cooperation between the Internet platform and CCTV Spring Festival Gala began in the Spring Festival of 2014, and this year is the ninth year. In the first few years, Tencent’s WeChat and QQ, Ali’s Alipay and Taobao created the New Year custom of online red envelopes for the Spring Festival, and expanded the online payment business with the Spring Festival red envelopes as the starting point; In the following 2020-2022, Aauto Quicker, Tik Tok and VideoNo. successively won the sponsorship rights of CCTV Spring Festival Gala with huge sums of money, and fulfilled their demands of promoting life and bringing forth new ideas through new forms of entertainment such as online interaction and fun play.

The rise of live broadcast with goods has set off a transition from consuming online content to buying physical objects online. As early as this year’s New Year’s Day, platforms such as Aauto Quicker and Tik Tok took the lead in opening the New Year’s Day activities, and opened up online channels for users to spend the New Year and buy new year’s goods through activities such as brand welfare purchase, origin new year’s goods and anchor challenge. According to iResearch’s China Live E-commerce Industry Research Report in 2021, by the end of 2020, the number of live webcast users in China has reached 617 million. Among them, the number of users ordering live broadcasts reached 388 million, accounting for 66.2% of users watching live broadcasts, that is, nearly two-thirds of users made purchases after watching live broadcasts.

A person familiar with CCTV’s cooperation in the Spring Festival Evening revealed to the Beijing News Shell Finance reporter that CCTV divides the copyright of the Spring Festival Evening into several types, including live video, recorded video, short video, highlights, social communication and hosting population broadcast. The price ranges from tens of millions to hundreds of millions. People in the industry generally believe that with the development of mobile Internet, users are increasingly unable to meet the one-way communication mode of "you pass me and I receive". Even a strong IP (intellectual property) like CCTV Spring Festival Evening needs to find ways to reach young audiences more easily. The short video and live broadcast platforms such as Tik Tok, Aauto Quicker and Video Number also need to sink further to gain more users, which makes their combination with the Spring Festival Evening seem logical.

Spring Festival Evening needs young people, and short videos are eager to pull new ones.

If the Spring Festival is the most important festival for Chinese people, then the CCTV Spring Festival Gala is as indispensable as the jiaozi at the banquet. However, with the development of mobile video technology, the Spring Festival Gala has gradually become a "background" under the dense barrage of live broadcast platforms, a "material library" for editing short videos by people in Weibo, and even an interactive project between Tik Tok, Aauto Quicker and video users.

On January 30th, the day before the Spring Festival Gala of the Year of the Tiger of CCTV, Tik Tok and Aauto Quicker announced that they had reached a cooperation with the Spring Festival Gala of CCTV in 2022. Their rights and interests included live broadcast, playback, short video and interaction, and the competition was obvious.

Different from the horizontal screens in Tik Tok and Aauto Quicker, earlier (January 25th), WeChat Video became the exclusive cooperation platform for CCTV to watch the Spring Festival Gala vertically. Not only did the official announcement enter the video number in the Spring Festival Evening, but the filming team also specially arranged a number of vertical screen shooting positions to ensure high-quality live broadcast from a unique perspective. Wechat also provided blessings, red envelopes, friends circle, status and other requirements for the vertical screen live broadcast of the Spring Festival Evening, and even exposed the "live broadcast" column of the "Discovery Page" to all WeChat users on the day of the Spring Festival Evening.

According to the data provided by Tencent, before the opening of CCTV Spring Festival Evening live broadcast, more than 1.95 million people had reserved live broadcast on the video number. On New Year’s Eve, more than 120 million people watched the Spring Festival Evening on the WeChat video number "Vertical Screen". The number of likes in the live broadcast of the Spring Festival Evening video number exceeded 350 million, the total number of comments exceeded 9.19 million, and the total number of reposts exceeded 5.51 million.

The cooperation between CCTV Spring Festival Evening and short video platform is more and more like a feast of copyright distribution.

The data shows that before the opening of CCTV Spring Festival Evening live broadcast in 2022, more than 1.95 million people had reserved live broadcast on the video number. On New Year’s Eve, more than 120 million people watched the Spring Festival Evening on the WeChat video number "Vertical Screen", and the number of praises in the live broadcast of the Spring Festival Evening video number exceeded 350 million times.

The short video platform that binds CCTV Spring Festival Evening also has its own considerations. According to the data, in 2021, Tik Tok, as the exclusive interactive partner of CCTV Headquarters Spring Festival Evening, had a total of 70.3 billion interactions with red envelopes that night, with a total of 1.221 billion people watching CCTV Spring Festival Evening live through Tik Tok. In 2020, Aauto Quicker "hand in hand" CCTV Spring Festival Evening, with a cumulative audience of 780 million in the live broadcast room, and the audience’s participation in the red envelope interaction in the Spring Festival Evening through Aauto Quicker exceeded 63.9 billion. Wechat, on the other hand, successfully promoted the Spring Festival red envelope through cooperation with CCTV Spring Festival Gala many years ago, and also achieved "overtaking in corners" in the field of mobile payment.

People in the industry generally believe that with the development of mobile Internet, users are increasingly unable to meet the one-way communication mode of "you pass me and I receive". Even a strong IP (intellectual property) like CCTV Spring Festival Evening needs to find ways to reach young audiences more easily. Short video and live broadcast platforms, such as Tik Tok, Aauto Quicker and Video Number, also need to sink further to gain more users, which makes their combination with the Spring Festival Evening seem logical.

Both virtual entertainment and physical consumption should be grasped?

Since the launch of CCTV Spring Festival Evening, sketch programs have been deeply loved by users, and even the dress of actors has become a topic of relish. The pink coat worn by Niu Li at the Spring Festival Gala in 2010, the purple sweater worn by Jia Ling in 2015, the pink sweater worn by Zhang Xiaofei in 2020 and this year’s "I don’t know the color" coat in Zhang Xiaofei are all eye-catching. Many people took photos and went to the e-commerce platform to search for orders, and many people bought and sold the same model on the short video platform.

As early as this year’s New Year’s Day, Aauto Quicker, Tik Tok and other platforms took the lead in opening New Year’s Day activities, through brand welfare purchase, new year’s goods of origin, anchor challenge, category day and other activities. According to the Data Report of "Tik Tok Good Goods and New Year Festival" in 2022, from January 1 to January 16, the cumulative time of the e-commerce live broadcast room in Tik Tok was 31.71 million hours, and the cumulative number of viewers in the live broadcast room reached 42.4 billion. The Consumption Trend Report of 2022 Aauto Quicker Quality New Year Festival shows that Changchun and Guangzhou are the most diligent in broadcasting the New Year Festival, while users in Beijing and Shenzhen have the highest consumption of new year’s goods. Middle-aged people and women are the main consumers of new year’s goods, and many categories of authentic new year’s goods such as food and drinks, beauty and skin care, clothing and jewelry, and household appliances are selling well.

As of June 2021, the number of short video users in China has reached 888 million. With the huge scale of users and the advantages of short video and live broadcast in content display, user interaction, propagation fission and so on, Tik Tok and Aauto Quicker have continuously planted high-quality short video content, live broadcast with goods and other forms in the past two years, further affecting users’ online and offline consumption habits.

A senior e-commerce person with experience in many e-commerce platforms commented and told Shell Finance reporter: "Tik Tok and Aauto Quicker cut e-commerce cakes in the way they are best at. From the perspective of realization, games are the best, followed by e-commerce. The short video and live broadcast of traditional consumer content are very dependent on the head anchor to’ eat’. Even if the platform makes money, it will be divided into a large piece by the anchor. Therefore, it is of course good for the live broadcast and short video platform to cut the cake in the field of e-commerce. If their users settle down in the future, get through social attributes and enrich SKUs (inventory units), there is still room for imagination. "

In the eyes of many people in the industry, Tik Tok follows a centralized traffic distribution method, and its model is more like Tmall’s B2C (brand merchants to consumers). For example, it uses self-built applets to attract brand customers to settle in, and gathers network celebrities to act as "shopping guides" for its own shelf goods; Aauto Quicker is still decentralized, and its model is more like C2C (individual seller to consumer) of Taobao. Aauto Quicker compares itself to the community, and compares different forms of e-commerce to "the canteen, supermarket and even department store in the community".

In terms of infrastructure, apart from building the bottom e-commerce page (shelves or secondary pages) and accessing external partners such as Taobao and JD.COM, the layout of Tik Tok and Aauto Quicker is also slightly different. Tik Tok has opened a small store entrance for brand merchants, added the function of commodity search, and purchased a payment license. In addition, Tik Tok store must be used in live delivery, so the meaning of self-built e-commerce platform is very obvious. Aauto Quicker has built a shopping cart (yellow car) and a logistics tracking system, optimized the combination of e-commerce and short video, opened an e-business school, improved the traffic delivery rules, and regarded e-commerce as a supplement to ecology.

From local life to industrial belt, short video platform has stepped into new consumption deep water area.

The three Spring Festivals affected by the epidemic are subtly changing the habits of users to "eat, drink and be merry". In addition to live broadcast, Tik Tok and Kuaishou’s shop-visiting anchors, as creators with their own traffic and trust, are constantly attracting users to search for local life content on the platform through shop-visiting videos and live broadcast coupons, which has also brought a new wave of traffic dividends to offline businesses. At present, Starbucks, Xicha, McDonald’s and other catering brands have settled in the short video platform.

Since blowing the horn of local life in 2020, Tik Tok and Aauto Quicker have continued to exert their efforts from the dimensions of supporting policies, content construction, activity creation and channel expansion. Take Aauto Quicker as an example. According to official data, it only charges 1% service fee to settled merchants, and merchants can set their own commission. In May last year, the function of "special group purchase" was fully opened at the entrance of the same city in Aauto Quicker. A month later, Aauto Quicker launched a small program "Eat, Drink and Play in Aauto Quicker" on WeChat, selling low-priced meal coupons in a centralized way, hoping to get through the consumption link of "planting grass" combined with group purchase and "weeding".

According to the data of iResearch, the local life service market in China will be 19.5 trillion yuan in 2020, and it will grow to 35.3 trillion yuan in 2025. The entry of the short video platform has injected new vitality into the local life of this trillion-dollar track, which not only poses a certain threat to the established players in the industry, but also brings new development opportunities.

With the continuous exploration of short video platform to offline real economy, the mode of "live broadcast+industrial belt" has also developed. For a time, the live broadcast of "the first county", "the first town" and "the first city" in the industrial belt constantly emerged. According to the data released by Linyi Municipal Bureau of Commerce, in 2021, the number of registered live broadcast merchants in Linyi Aauto Quicker reached 160,000. By the end of July of the same year, there were more than 290 fans with over one million anchors. There are about 6,500 large-scale merchants, and the number of registered users ranks first in the country; The transaction volume ranks third in the country.

In addition, the short video platform is also expanding in influencing people. Aauto Quicker e-commerce data shows that among e-commerce consumers, the order volume of people over 60 years old in 2021 increased by more than 122% compared with 2020; The GMV data of people over 60 years old in 2021 increased by more than 159% compared with 2020; The consumption enthusiasm of the elderly over 70 years old exceeds that of the people over 60 years old. In addition, the order volume of middle-aged and elderly people over 45 years old increased by over 96% in 2021 compared with 2020.

Why do middle-aged and elderly people also begin to prefer e-commerce live broadcast? First, the short video live broadcast lowers the threshold of information acquisition, and you can get a more intuitive and comprehensive understanding of goods by watching videos; The second is that live e-commerce has actually changed the lives of middle-aged and elderly people; At the same time, after the middle-aged and elderly people have gained tangible benefits, their trust relationship with e-commerce anchors has also been strengthened, and the maintenance of word-of-mouth by merchants has also made this relationship enter a benign development.

According to the analysis, at present, short video and live broadcast platforms are not only tools to provide entertainment content for the public, but also satisfy more people’s demands for living, shopping and even making a living at the consumption level, and constantly drive the growth of the real economy. The acceptance of live e-commerce by middle-aged and elderly people further confirms that short video live broadcast platforms such as fast and shaking are becoming a useful supplement to the real economy. From the development of industrial belts to the placing of orders in live broadcast rooms, live e-commerce has gradually penetrated into all aspects of daily life, and new consumption patterns have also emerged.

Beijing News Shell Finance Reporter Bai Jinlei Editor Yue Caizhou Proofread Wang Xin

　　Gao Shuaiqi has begun to make plans for his graduate life, which will start in September.

　　■ Our reporter Jiang Peng

　　Gao Shuaiqi, a 26-year-old boy from Henan Province, is a food delivery rider. On July 7, he waited for a surprise on the way to deliver food: the admission notice from Shanghai Jiaotong University! Gao Shuaiqi was admitted as a full-time master by Kaiyuan Law School of Shanghai Jiaotong University.

　　"Welcome to Jiaotong University." Soon, Gao Shuaiqi’s story of postgraduate entrance examination was forwarded and praised by Weibo, the official of Shanghai Jiaotong University, and was blessed by many netizens.

　　"At that time, after I delivered the order in my hand, I immediately rushed home and opened the notice with my family." Gao Shuaiqi wants to share this joy with his family most, but his father actually doesn’t know anyone after a cerebral infarction. That day, seeing the name of Gao Shuaiqi written on the notice, Gao Fu was so excited that he cried.

　　Gao Shuaiqi wiped his father’s tears while trying to calm his heart. "Seeing my father’s tears, I just want to quickly take over the burden on him. Two years of hard work finally paid off. At that time, I couldn’t help but say to myself: It’s not easy! "

　　Yesterday, when the reporter dialed Gao Shuaiqi’s phone number, it was the late rush hour of food delivery. At the other end of the phone, the young man spoke quickly: "This is the busiest time of the day, and it happens to be the weekend, and it may end later. This summer vacation, I want to send more orders for the rest of my life. "

　　"I stood on the shoulders of my parents to get here today, and now it’s my turn to take care of them."

　　Gao Shuaiqi is a retired college student. In 2015, he was admitted to Zhengzhou University of Light Industry, majoring in marketing, and served as the monitor of the class. He also joined the party in college. However, the dull college life made him feel confused about the future. After much deliberation, Gao Shuaiqi decided to drop out of school for two years and sign up for the army.

　　The days when he was stationed in the frontier made him accustomed to hard work, and also shaped a strong, optimistic and fearless character. "After you come back, I know what I really want. I wanted to see a bigger world, so I began to work hard and decided to take an interdisciplinary examination. "

　　Who knows, when preparing for the postgraduate entrance examination, my father had an accident In August last year, Gao Shuaiqi’s father was hospitalized for cerebral hemorrhage, and then he was hospitalized several times because of cerebral infarction. Gao Shuaiqi suddenly became the pillar of the family. In April this year, after Gao Shuaiqi was admitted, he decided to be a courier brother first, so that he could have an income, reduce the family’s financial burden, and have relatively free time to take care of his family, and at the same time he could continue to prepare for the "law exam" (that is, the legal professional qualification exam).

　　"My father can’t speak clearly now, and he will play with fire and water like a child, which is basically inseparable from people. I stood on the shoulders of my parents to get here today, and now it’s my turn to take care of them. " Usually, apart from the stationmaster of the express workstation, few people know that Gao Shuaiqi supports a family of four by himself. Every afternoon, when others have a rest, he rushes home to cook for his younger brother in junior high school. It’s already eleven or two o’clock when he comes home after delivery at night, and then he reads and studies, sometimes reviewing until two or three in the middle of the night. Even during the two or three months in hospital with his father, in order not to fall behind in his studies, he made a review plan for himself in the ward: memorizing 5 questions and 1000 English words.

　　Gao Shuaiqi said frankly that he dropped out of school and signed up for the army at that time in order to get out of the comfort zone and figure out what he really wanted. Now the postgraduate entrance examination also wants to get out of the comfort zone. The reason why I choose the law major is that I hope I can help more people in the future.

　　He is "Forrest Gump" in the eyes of his colleagues, and his work is very poor.

　　Gao Shuai Banner has a nickname, Forrest Gump. One of his colleagues said that he was called "Forrest Gump" because of his seriousness and persistence. "He is a zero-bad-review takeaway here. He usually works very hard. In summer, at a temperature of nearly 40 degrees Celsius, he delivered the heaviest takeaway of 80 kilograms and sent it to the 14th floor on foot."

　　In Gao Shuaiqi’s eyes, "Forrest Gump" means "don’t lie flat and rot, use your own hands to support yourself and take care of your family". Now, Gao Shuaiqi has begun to make plans for his graduate life to be opened in September: study hard and pass the "law exam"; Next, practice well to increase experience and experience; Do more things of social value and help more people in the future.

　　He admits that he is still working as a courier brother, hoping to save one or two thousand yuan before school starts. After the start of school, he is going to join the work-study program and apply for a student loan. Of course, he does not rule out continuing to send takeout.

　　It is understood that Kaiyuan Law School of Shanghai Jiaotong University has contacted Gao Shuaiqi for the first time and introduced him to various funding policies of the college.

　　Guan Hannan, the relevant person in charge of the college, said that there is more than one similar student in Kaiyuan Law School. Their self-reliance, academic commitment and outstanding performance have also become role models for more peers to some extent. The college will also provide all kinds of support for these students.

　　This college has a WeChat group called "Kaiyuan Rongyao", and many members are students like Gao Shuaiqi. One of them is Huang Jiadong, a student from a poor mountain. Huang Jiadong, who is constantly striving for self-improvement, was admitted to Antai School of Economics and Management of Shanghai Jiaotong University, and then went straight to Kaiyuan Law School to continue his postgraduate studies. He also became a candidate for national college students’ self-improvement this year. Another student named Fang Chao is about to become Gao Shuaiqi’s classmate. During the epidemic, Fang Chao was an outstanding volunteer in his community … …

　　"Every one of them has encountered difficulties and twists and turns, but they all pursue their dreams with enthusiasm and persistence. I hope that their stories will encourage more candidates in this special exam season. " Guan Hannan said.

　　On the 28th, the State Council Press Office held a press conference, and the relevant person in charge of the National Internet Information Office introduced the relevant situation of the "Clear" series of special actions in 2023, which will focus on the rectification of "self-media" chaos and other issues.
