Editor’s note:Water is the source of life and is vital to human health. Drinking water can promote the body’s metabolism and absorption of nutrients, but drinking it wrong may be harmful to health. Therefore, how to drink water is very particular. Let’s take a look.

　　The misunderstanding of drinking water is constant

　　Last summer, the northern hemisphere continued to suffer from high temperature, and the number of patients with "water poisoning" in hospitals in many regions of Europe doubled. According to the Danish Local Times, some Danes drank a lot of tap water to cool off the heat, which caused them to get sick. Take Hawkbell Hospital as an example, the number of patients with "water poisoning" this summer is 10 times that of previous years. According to local doctors, drinking too much water will increase the water content of blood and reduce the sodium content, which will lead to the imbalance between salt and water. Severe imbalance may cause "hyponatremia", and patients may have brain swelling, headache and other phenomena, and even lead to epilepsy, shock and death.

　　Zhao Feihong, director of the Health Drinking Water Professional Committee of Beijing Health Protection Association, said that when people sweat a lot, in addition to water loss, many electrolytes mainly sodium salts will also be discharged with sweat, and people often drink a lot of water to replenish water. This is a misunderstanding. Drinking pure water alone can’t replenish the missing electrolyte, and even further dilute the electrolyte concentration, which leads to the imbalance of the ratio of water and electrolyte in human body and triggers the body to produce different degrees of stress response. "However, in general, drinking more water will not cause serious problems ‘ Poisoning ’ Only people with poor kidney and cardiopulmonary function need special attention. "

　　Zhao Feihong said that there are still many misunderstandings about people drinking water. First, drinking water too fast and replenishing a large amount of liquid in a short time will increase the burden on organs such as the heart and kidneys, which may easily lead to headache, edema and elevated blood pressure. Second, drinking water is too "ice". When the body temperature is high, it is best not to drink drinks below 5℃. Drinking cold water will stimulate the stomach and lead to stomach cramps and diarrhea.

　　Water accounts for 60%~70% of human body weight, and plays an important role in forming whole body tissues, regulating body temperature, promoting metabolism of various systems of the body, and assisting absorption, transportation and excretion of various substances. Batman, an American doctor of medicine, recorded many studies in the book "Water is the Best Medicine", which proved that healthy drinking water can relieve hypertension, diabetes, allergies, asthma, cancer and other diseases. He once cured more than 3,000 patients with water.

　　How to drink water correctly

　　When you feel thirsty, the water loss of adults is about 2% of your body weight, and that of children is about 2%~5%. At this time, your body functions begin to be affected. Lack of water can also lead to loss of appetite, depression, dry skin, hoarseness and general weakness, which can be life-threatening in severe cases. Zhao Feihong suggested that you should develop the habit of taking the initiative to drink water, and don’t wait until you are thirsty. Drinking water should follow the principle of "small amount and multiple times": 100~150 ml is suitable for each time, and the interval is about half an hour; Drinking water with a small mouth is more thirst-quenching than pouring water with a large mouth, which is beneficial to human absorption.

　　There are four best times to drink water. After getting up in the morning, around 10 am, 3-4 pm and before going to bed at night, it is currently recognized as the four "best drinking periods" in a day.

　　Zhao Feihong explained that people do not drop water during sleep, and the formation of nocturia and the loss of water through breathing and skin make the body in a physiological state of water shortage, which leads to the increase of blood viscosity and the accumulation of metabolites in the body. Therefore, drinking a glass of water half an hour before going to bed can alleviate the above phenomenon and reduce the risk of cerebral thrombosis. Drinking a glass of water after getting up in the morning takes only 20 seconds, and water can enter the blood, which makes the blood dilute rapidly and improves the water shortage at night.

　　At least 1.5 liters per day. According to Dietary Guidelines for China Residents (2016), the recommended daily drinking water for adults is 1.5~1.7 liters. Gu Chuanling, deputy secretary-general of the Capital Health Food Nutrition Society, said that people’s daily drinking water can be appropriately increased according to the following factors:

　　1. Living environment. In hot weather, people sweat more and lose water faster, so it is necessary to increase water supply. It is easy to dry in autumn and winter, and in the heating room in northern winter, the water evaporates quickly, so it is necessary to increase the amount of drinking water.

　　2. Dietary factors. The diet is salty, and when the human body discharges excess salt, it needs to consume more water; If you eat food containing more protein, your blood osmotic pressure will increase slightly, and you need extra water to excrete the urea produced by protein. At these times, you need to pay attention to drinking more water.

　　3. Physical condition. When a cold has a fever, the human body will lose a lot of water in the form of sweating, so it is necessary to increase the amount of water.

　　Boiled water is best.

　　China Nutrition Society recommended that boiled water is the most suitable drinking water for human body. American scientists have found that when the boiled tap water is cooled to 25~30℃, the chlorine content is the lowest, and the biological activity of the water is also increased. It can easily penetrate the cell membrane, which can promote the body’s metabolism, enhance immune function and improve the body’s disease resistance.

　　Sweet drinks, functional drinks, fruit juice, strong tea and coffee can’t completely replace drinking water. Zhao Feihong said that all kinds of sweet drinks and fruit juices are high-sugar and high-calorie drinks. The human body needs to consume more water to complete metabolism and cannot replenish water well. Functional drinks, strong tea and coffee all contain caffeine, which has diuretic effect in itself and is not conducive to human hydration.

　　Special people pay attention to drinking water

　　Children. Dietary Guidelines for China Residents, Balanced Dietary Pagoda for Preschool Children in China and Dietary Guidelines for School-age Children in China suggest that the water demand for children under 10 years old varies with age: 6 months to 1 year old, and the total daily water intake is 900 ml (milk/food+drinking water); 1~2 years old, the total water intake is 1300 ml (milk/food+drinking water); 2~3 years old, drinking 600~700 ml; 4~5 years old, 700~800 ml; 5~7 years old, 800 ml; 7~10 years old, 1000 ml. Gu Chuanling reminded that children’s initiative to drink water in time is generally poor, and they like to drink sweet drinks. Parents should do a good job of monitoring and remind their children to drink water in time.

　　Lactating women. About 90% of milk is water, and milk secretion is closely related to the daily intake of water. Drinking more water under the condition of ensuring balanced nutrition is beneficial to milk secretion. Gu Chuanling said that they are generally recommended to drink more water than ordinary women, about 2.1 liters per day.

　　Old man. Old people tend to urinate frequently, and if they don’t drink water regularly, they are prone to thick blood and high blood fat, which will eventually cause a series of metabolic diseases. Therefore, the elderly should drink water frequently, and the amount of drinking water should be increased accordingly, which can be judged according to the color of urine: if the urine is light yellow, 250 ml of water should be replenished in time; If it is brown, it means that the body is seriously short of water, and you should drink 500 ml of water.

　　Office workers. Office workers can replenish 200 ml of water in time after arriving at the company every day, which is conducive to promoting brain activity and working concentration. In addition, office workers who sit indoors for a long time are prone to get fat. Drinking 200 ml of water half an hour before meals is conducive to increasing satiety and reducing food intake to some extent.

　　Manual workers. Athletes and outdoor workers need to replenish water in time after a lot of physical activities. Zhao Feihong suggested that these people can properly replenish water about half an hour before physical activity. During the activity, they can replenish water with a small amount of water. After the activity, they are not in a hurry to replenish water. After a while, they can replenish water and drink some light salt water appropriately.

　　Poor spleen and stomach, drink less water.

　　It is recorded in the medical book "Four Sages Heart Source" in Qing Dynasty: "Shui Gu enters the stomach, the spleen and yang are grinded, and the dregs are passed down, but for feces drowning, the essence is served, and it becomes qi and blood." If the spleen yang is insufficient (spleen yang is the function of spleen and stomach), the digestion and absorption of water is weak and it cannot be turned into qi and blood. People with poor spleen and stomach, such as loss of appetite, nausea and vomiting, frequent hiccups, abdominal distension and diarrhea, epigastric discomfort and other symptoms, had better drink less water in the morning to avoid further affecting the function of spleen and stomach.

　　Be careful when drinking water because of lung dysfunction.

　　Traditional Chinese medicine believes that besides breathing, another important function of the lung is "attending festival", including "dredging water channels". "Waterway" refers to the way that water and liquid move, that is to say, the lung can regulate the metabolism of water and liquid, mainly through the spreading and descending of the lung, and transport body fluid to all parts of the body by using lung qi, which can also promote the water and liquid to be lost to the bladder, so as to keep urine flowing smoothly. If lung function is impaired, such as frequent chest tightness, shortness of breath, wheezing and palpitation, cough with excessive phlegm, nasal congestion and runny nose, etc., water metabolism will also be poor, and drinking water indiscriminately will aggravate symptoms.

　　Traditional Chinese medicine believes that the kidney controls water and the bladder controls the gasification of water. Kidney plays a key role in regulating and maintaining water-liquid balance in the body. If there is a problem with kidney function, pay more attention to drinking water, otherwise there will be edema and unfavorable urination. When there is no need for drinking water, don’t force yourself to drink water, but keep your body in a state of peace of qi and blood.

　　Drinking too much water increases the burden.

　　Many chronic patients have thick blood and hope to dilute it by drinking more water. In fact, water can’t enter blood vessels immediately. Traditional Chinese medicine believes that the human body is a circular whole, and the metabolism of water should be completed under the coordination of various organs and tissues. If there are problems in the gasification of triple energizer, the transfer of viscera and the operation of qi and blood, water will not achieve the purpose of diluting blood, but will increase the burden on the heart, lungs, spleen and kidney. Dietary Guidelines for China Residents (2016) suggests that the daily drinking water should be kept at 1500~1700 ml.

　　Huang Yuanyu, a famous doctor in the Qing Dynasty, said: "If qi does not turn into water, it will stagnate on the upper side and become phlegm; if water does not turn into qi, it will stop accumulating on the lower side and become drinking. Generally speaking, yang deficiency leads to soil failure, and the golden water is swollen, all of which have the disease of retention of phlegm and retention of drink. Covering the phlegm and drinking, corruption and stagnation hinder the road of qi and blood around the week, and the spirit of the spirit is close to the aid. All diseases start and the changes are constant. " It means that if there is no yang, such as yang deficiency and spleen deficiency, and lung and kidney are not transported, water will stagnate into phlegm and form phlegm-drinking disease. Phlegm can block the circulation of qi and blood, leading to many diseases. People who often drink too much water have a heavy burden on the spleen and kidneys, and tend to age faster than others, and some chronic diseases will come faster and more than others.

　　Traditional Chinese medicine believes that the accumulation of water and fluid in the body will also form phlegm, and further accumulation of phlegm can become phlegm nuclei, such as scrofula, gall tumor and other diseases; Or form nodules and lumps with blood stasis. In clinical practice, some patients with cyst have reduced curative effect due to improper drinking water, and the curative effect will be obviously improved after changing improper drinking habits.

　　Phlegm drinking and phlegm turbidity are unique concepts of traditional Chinese medicine, which can be divided into tangible and intangible categories. Tangible, sticky is called phlegm, and thin is called drinking. Invisible phlegm and drink can cause many symptoms, such as dizziness, nausea and vomiting, shortness of breath, chest tightness, palpitation or madness, coma, etc., but no substantial phlegm and drink can be seen. Modern medical research has found that phlegm is related to many diseases such as body immunity, hypertension, hyperlipidemia, coronary heart disease, cancer, asthma and mental illness.

　　Four Special Reminders of Drinking Water

　　1. Don’t drink a lot in a short time. Drinking a lot of water in a short time will increase the amount of urination and perspiration. The former will increase the burden on the kidneys, while the latter will cause excessive loss of salt in the body, leading to electrolyte disorder.

　　2. Clear and colorless urine means enough drinking. How to judge whether you have drunk enough water, it is recommended to observe your urine color every day: if it is light lemon color, it means that the water in your body is in the best state; If the urine is clear and colorless, the water intake should be slightly reduced; If the urine is yellow, you need to replenish water in time.

　　3. Don’t drink before and after eating a big meal. People’s stomach space is limited. If you drink a lot of water before or after meals, it will occupy the space, causing abdominal distension and abdominal pain, which is not conducive to gastrointestinal peristalsis and leads to indigestion. Under normal circumstances, it is recommended to drink water half an hour after meals.

　　4. Avoid drinking immediately after long-term exercise. Drinking water immediately after exercise will lead to a sudden increase in blood volume in the body and increase the burden on the heart. A large amount of water stored in the stomach will also affect the rise and fall of diaphragm, causing discomfort such as chest tightness and asthma. It is suggested to sit down and rest for 10 minutes after exercise before drinking water to give the body a buffer time; At the same time, just drink 150 ~ 200ml each time, and don’t drink too much at a time.

　　 If the weather is fine, China’s first domestic civil large passenger plane C919 will start its first blue sky trip on May 5, which marks a major leap in the field of civil aviation in China.

　　 China’s civil aviation industry has been in a state of "buying imported goods" since the research and development of the domestic "Yun Shi" passenger plane stopped in the 1970s.

　　 The turnover of civil aviation passengers in China has rapidly climbed from 23.048 billion person-kilometers in the early 1990s to 727.07 billion person-kilometers in 2015, with a compound annual growth rate of 15%.

　　 C919 was developed in 2008, and now it is about to make its first flight. Every "growth process" of C919 has attracted much attention. Behind this big domestic bird, groups of young talents are also growing sturdily. From the "post-70s" in the early 20th century to the "post-80s" and "post-90s" now, behind the first flight of C919, there is a solid backing composed of young talents.

　　 Data from Commercial Aircraft Corporation of China (hereinafter referred to as China Commercial Aircraft Corporation) show that more than 70% of the company’s young people are under the age of 35. When experts from related international fields visited Comac in China, they expressed such feelings: "The impressive thing about China Big Aircraft is not only the technology, but also the young people who are eager to fly behind it!"

　　The domestic large passenger plane C919 was tested at Shanghai Pudong Airport for high-skid lifting of the front wheels. Xinhua news agency

　　 570 aircraft orders and 60% localization rate

　　 Speaking of C919, I have to talk about the topic of "localization". Fans of the aviation industry may not forget the low standard of "the localization rate is more than 10%" at the beginning of the C919 project, and even this low requirement was considered by some senior aircraft enthusiasts to be difficult to achieve at that time; Today, the finished products delivered off the assembly line not only get 570 orders, but also have a localization rate of nearly 60%.

　　 Some people question that the core engine and other components are all imported. Is the C919 a domestic product?

　　 China Youth Daily Zhongqing Online reporter learned that the nose of C919 comes from Chengdu Aircraft Industry Group, the wing comes from Xi ‘an Aircraft Industry Group, the front and rear fuselage comes from Nanchang Hongdu Aviation Industry Group, and the front section of the rear fuselage comes from Shenyang Aircraft Industry Group.

　　 As for the "kernel" of large aircraft, such as engine, communication and navigation equipment, C919 aircraft chose two paths — — First, foreign original factories and domestic joint ventures; Second, the original import, to a certain extent, to achieve partial domestic, and finally to achieve full domestic.

　　 "Realizing all localization in the end" is the "technical market threshold" set by Comac China when purchasing original imported products. That is to say, once a product is purchased by Comac China, there is only one final "outlet" — — Gradually localized. This is the basic agreement between the product manufacturer and Comac China.

　　 At the beginning of the C919 project, Li Keqiang, Premier of the State Council of the People’s Republic of China set a basic principle for domestic large aircraft — — Independent design, system integration, global procurement, and gradual domestic production.

　　 Many people think that assembling some imported products is actually not too difficult and has no technical content. However, an interview with China Youth Daily and Zhongqing Online reporter found that for China people who have not been exposed to the research and development of civil large passenger aircraft for more than 30 years, the design, production and manufacturing process of C919 itself is full of innovations and challenges.

　　 Take fiber material as an example, 15% of the fuselage of C919 is made of resin-grade carbon fiber material, which is the first time that this material has been widely used in large-scale civil passenger aircraft, and the utilization rate of this material in traditional large-scale passenger aircraft is only about 1%.

　　 Others don’t use it, not because the material is not good, nor because the price is too expensive, but because this material requires too high installation accuracy, ordinary people can’t complete the accuracy required for "docking" with this material, so it is not used much.

　　Gao Yuan (first from the right)

　　 Gao Yuan, deputy director of the aircraft assembly workshop of Shanghai Aircraft Manufacturing Co., Ltd. (hereinafter referred to as Shangfei Company), told China Youth Daily and Zhongqing Online reporter that the resin-grade carbon fiber material used in C919 is light in weight, and its weight can be 80% lighter than that of ordinary traditional materials under the premise of the same strength; Its fatigue life is also longer. Generally, the service life of metallic silver material is 20 years or 60,000 flight hours, but it can reach 30 years or 90,000 flight hours, and the structural life can be increased by 50%.

　　 One problem is that when this material is used in aircraft manufacturing, the docking accuracy required is three or four orders of magnitude higher than that of rockets, and the method of realizing "accuracy" by traditional measuring tools is not applicable.

　　 In the manufacturing process of C919, China people realized the automatic docking of large parts for the first time. Through laser positioning and tracking, the docking accuracy can be two orders of magnitude higher than in the past.

　　 With the "shell", what about the core?

　　 For example, if you cut a small hole in the outer shell of an airplane and fill it with a composite material, to what extent do you think it should be filled? The requirement of C919 is that it is invisible to the naked eye, and the "step difference" between the "patch" and the raw material is within 0.08 mm..

　　Wang Hui (center)

　　 What is the concept of 0.08 mm? It is several orders of magnitude thinner than the thickness of mobile phone film. "Invisible to the naked eye, experienced masters can touch the difference with their hands." Wang Hui, deputy director of the manufacturing engineering department of Shanghai Aircraft Corporation, told the reporter that without a certain technical level, even if a Boeing 747 is disassembled and put in front of you, it is impossible for you to assemble it again.

　　 Wang Hui said that the Manufacturing Engineering Department is equivalent to a translator, and it has to translate the drawings of the upstream aircraft design company into construction plans and technological processes that front-line workers can understand. Even if it is such a small and insignificant step, China people will go abroad to learn from it.

　　 Before C919 started construction, COMAC cooperated with McDonnell Douglas to manufacture aircraft of McDonnell Douglas 82 and McDonnell Douglas 90. In this process, McDonnell Douglas provided the process flow, and COMAC was responsible for the production. To a certain extent, the cooperation with McDonnell Douglas makes the manufacturing engineering department of Shangfei Company grow gradually, and finally it can master the process independently.

　　 Even so, some people will feel disdainful. Isn’t it just to build a shell? How much of the "core" is the result of China people?

　　Zhou Qiwei

　　 Zhou Qiwei, 30, has the most say in this. All the cable-related departments on C919 are under his control and his team’s control. There are 24 of them, with an average age of around 30, but they are responsible for the most critical link in the normal operation of a plane — — 725 cables are arranged and laid, and 150,000 parts are installed and assembled.

　　 These cables, like "nerve lines" and "blood vessels" in the human body, will lead to "organ" failure if they are not careful. The display may not be on, the throttle lever may be out of control, and the joystick may fail … … And all wiring, not a single drawing can solve the problem.

　　 "Drawings are subjective designs, and everything is subject to the real thing." Zhou Qiwei told reporters that wiring often reflects the actual situation to the design team, and many design ideas cannot be realized in the actual wiring process. At this time, the wiring team also has to undertake some "design functions", propose modifications and feedback to the designer, and then wait for the designer to re-issue more realistic drawings. "Without talent, you can’t do this job."

　　 The young and beautiful Gong Wenxiu is also responsible for the control of the "core" inside the aircraft. She is a member of the configuration management team of Shanghai Aircraft Design and Research Institute. Her job is to adjust the technical state of the whole machine to the best before the first flight. The navigation and communication system of aircraft can not be used directly after being bought and installed. It needs constant debugging and constant correction of system errors before it can operate normally.

　　 Gong Wenxiu’s job is to "correct mistakes". Every inspection, she has to carry a thick stack of process specification materials in her hand and check them one by one. She and her team have to evaluate some system functions that cannot be realized for some reason. Why can’t they be realized? What is the impact on the first flight? Is it necessary to achieve it? Then give feedback.

　　Scale testing machine

　　 What does "939, 949" look like after C919?

　　 If the aforementioned "handsome men and beautiful women" are all preparing for the first flight of C919, then the following one is preparing for the future "C939 and C949".

　　 His name is Zhang Chi, deputy head of the future product and technology research team of Beijing Civil Aircraft Technology Research Center (hereinafter referred to as Beiyan) of Comac China. He and his team are responsible for the "future model" of the C919. They gave themselves a rather dreamy name — — Dream studio, responsible for the "Lingque" project.

　　 The "Lingque" project, to put it more popularly, is to design and develop a scaled-down large aircraft. This "Lingque" aircraft is more futuristic, unmanned and small, and the cost of an aircraft is less than 1% of that of the C919. But it carries the future of China’s big plane dream.

　　 Lingque aircraft is a scaled verification model. It costs a lot to build a large plane and bears high risks in the field of innovative technology, but the smaller version of the "Lingque" can be more "dreamy" with low cost.

　　 The latest "Lingque B" fuselage and wings are integrated, which is more economical and comfortable. Its tail has only two pieces, which is less resistant than the general three-piece tail plane.

　　 This team, which is all composed of young people around the age of 30, is now doing research and development to solve the world-wide problems such as expensive air tickets and high fuel consumption of aircraft.

　　Franky Zhang

　　 "Real innovation is not afraid of failure." Zhang Chi said that this team often received suggestions from peers in the past, "Is your plan feasible? Maybe not? "

　　 However, Zhang Chi told reporters that in all kinds of discussions, Dream Studio has made nine scale testing machines since 2012, and there have also been cases in which small planes got out of control after take-off and ground dispatching was unsuccessful. "Without failure, it is not innovation, that is called imitation. We don’t do this. "

　　 Zhang Chi said that youth is the capital of Dream Studio.

　　 China Youth Daily Zhongqing Online reporter learned that Comac China has set up a total of 349 youth commandos, such as the young commandos for aircraft-level joint test of the C919 project of COMAC, and the young commandos for the assembly of the C919 large passenger aircraft system in the aircraft assembly workshop of COMAC, and named 60 youth civilization numbers, such as the composite material/structure research team of the North Research Center and the young technical team for field engineering of the test flight center.

　　 Comac youth played a great vanguard and vital role in the flight test evidence collection of ARJ21 passenger plane, route demonstration operation, design and development, final assembly and manufacturing of C919 large passenger plane, and preparation for the first flight — — Ten youth innovation and entrepreneurship teams, with more than 230 members and an average age of less than 30, have undertaken 37 key technical problems of civil aircraft, including the control law of C919 large passenger aircraft.

　　 Zhongqing Online Shanghai, May 4th

CCTV News:At the beginning of March, spring is blooming and full of vitality. With a wisp of spring breeze blowing, fine grass is drilled out of the earth, and many flowers contain fragrant flowers. As far as you can see, grass grows everywhere and the spring is beautiful. At the beginning of this news, we walked into China in spring and enjoyed the beautiful spring scenery of China.

Yangzhuo Yongcuo Lake: Snow-capped Jasper Lake is melting.

What you are seeing now is Yangzhuo Yongcuo Lake located in Langkazi County, Shannan, Tibet. In the embrace of the peaks, the Yanghu Lake in early spring has begun to thaw slowly, and the sun sometimes melts the ice through the clouds, and a pure blue gem, such as clear jasper, is embedded in the vast plateau. Yanghu Lake covers an area of 637 square kilometers, with an altitude of 4,441 meters and a depth of 60 meters. Its beautiful and unique scenery has attracted many tourists. In 2021, Yanghu Scenic Area received more than 430,000 tourists, a year-on-year increase of 36.13%.

In spring, everything on the earth recovers, and Altun Mountain is full of vitality.

We are now in the Altun Mountain National Nature Reserve in Bayinguoleng Mongolian Autonomous Prefecture, Xinjiang, with an average elevation of 4,500 meters. It is the first protected area in China, which focuses on the fragile ecological environment of the plateau. The protected objects are plateau ungulates represented by Tibetan antelopes, wild yaks and Tibetan wild donkeys, and it is called "the world of plateau ungulates". At this moment, the vast lake Aqike on the towering plateau is melting and the ice layer is cracked; The thin ice of the sand lake in the hinterland of Kumukuri desert melts away, which complements the golden sand mountain and the vast blue sky; On the boundless wilderness, herds of Tibetan wild donkeys run freely, and wild yaks live by water, full of vitality everywhere.

Tongling, Anhui Province: Plum viewing was just when the windward flowers were blooming.

It’s sunny in spring, which is the time to enjoy flowers. Now, what we see is Meiyuan in Tianmen Town, Tongling, Anhui Province. Plum blossoms in full bloom show their beautiful posture in the warm care of the early spring sunshine. From a distance, they are like soft rosy brocade in the countryside of Shan Ye, and from a close look, branches and branches are scattered and colorful. Tourists are in it, and the fragrance is fragrant and refreshing. There are nearly 10,000 plum blossoms here, including more than 110 varieties such as Hongmei, Bai Mei, Green Plum and Huangmei, which are blooming one after another, attracting many tourists to enjoy the flowers. In recent years, the local area has explored the beautiful rural scenery resources, promoted the deep integration of agriculture, forestry and tourism, promoted farmers’ income, and injected new vitality into rural revitalization.

Tongan, Fujian: Cherry blossoms are fragrant and full of tea mountains, and flowers bloom in spring to attract guests.

Following the camera, we came to Tong ‘an District, Xiamen, Fujian Province. The traditional ancient village here: Baijiao Temple Village, with thousands of alpine cherry blossoms planted according to the mountain situation, is in full bloom in the spring, full of vitality, and looks like a cloud from a distance, which is in harmony with the green tea mountain terraces.

People stroll along the cherry blossom trail, facing the warm spring wind and feeling the pleasant fragrance of flowers. In recent years, the local area has made use of mountain cherry blossoms, tea trees and other special resources, adhered to ecological construction, revitalized green mountains and green waters, and vigorously developed farmhouse music, tea economy and rural tourism. In 2021, the per capita income of villagers was nearly 50,000 yuan.

Rongcheng, Shandong Province: The wintering swan began to move northward one after another.

This is Shandong Rongcheng Swan National Nature Reserve, and these swans are constantly stretching their wings to prepare for the northward migration. With the temperature rising and the weather getting warmer, tens of thousands of swans who wintered here began to move northward one after another. According to statistics, more than 3000 swans have set foot on the journey. The reserve has prepared enough corn, and arranged special personnel to feed it at a fixed point, quantitatively and timely during the flying practice of the big swan to help them reserve enough energy for the long journey. This year, Rongcheng Swan National Nature Reserve joined East Asia — Australia’s migration zone partner agreed to the migration zone protected area network, becoming the 20th migration zone protected area network site in China.

　　The Lantern Festival is approaching. According to the traditional custom, Yuanxiao not only enjoys lanterns, but also eats glutinous rice balls, which means reunion. Yu Ting, deputy chief physician of the Department of Gastroenterology, Zhongda Hospital affiliated to Southeast University, reminded the public that although glutinous rice balls are delicious, if they are eaten too much at one time, it will easily lead to some diseases, especially for the elderly and children with weak digestive function.

　　Yangzi Evening News/Zi Niu News reporter Yang Yan

　　Eating 4-8 at a time is enough.

　　As the Lantern Festival is approaching, many people have already prepared glutinous rice balls at home, and they can’t finish one meal. They eat breakfast, extra meals and even supper for many days, and they accidentally overdo it. Deputy Chief Physician Yu Ting pointed out that most of the glutinous rice dumplings currently on the market are glutinous rice products, which are difficult to digest, especially for the elderly with weak digestive function. At the same time, most of the dumplings are filled with sesame seeds and bean paste, and some fillings may contain a lot of oil and sugar, which is easy to cause the increase of blood sugar and blood lipid after eating by the elderly, which is not conducive to health.

　　Experts remind: You should not eat too much at a time. Eating a small bowl (about 4-8) is enough. For patients with basic gastrointestinal diseases (such as gastroduodenal ulcer, acute and chronic gastrointestinal inflammation, etc.), patients with liver disease and acute and chronic pancreatitis, don’t be greedy, just taste one or two. While eating glutinous rice balls, it is recommended not to eat other foods with high sugar content, especially those with diabetes. In addition, it is necessary to reduce the intake of other staple foods.

　　Old people and children should pay attention to chewing slowly.

　　Although the dumplings are delicious, for the elderly and children, they must eat slowly, eat slowly, and never swallow. This is because the elderly are older, and their chewing ability and saliva secretion are reduced; However, children’s swallowing function is not so coordinated, cough reflex is weakened, and foreign bodies in the airway are prone to occur, especially glutinous rice soft food like glutinous rice dumplings, which is very dangerous once it is choked into the airway. Experts remind: Tangyuan is soft, so you should eat it slowly to avoid increasing the burden on your stomach and causing discomfort in your stomach. At the same time, it can also avoid burns.

　　Tangyuan is rich in sugar and high in calories. Therefore, many people think that eating tangyuan at night is easy to gain weight, and it seems more appropriate to eat it in the morning. Actually, glutinous rice balls are not suitable for breakfast. This is because dumplings are mostly made of glutinous rice, which is not easy to digest. Coupled with the large amount of oil in the dumplings, it adds a burden to the gastrointestinal tract. When people get up early, the gastrointestinal function is the weakest. At this time, eating so many indigestible things at once will definitely make the gastrointestinal tract overwhelmed. It is best to eat glutinous rice balls at noon. At this time, the gastrointestinal function of the human body is the strongest, and there is enough time to digest excessive calories in glutinous rice balls.

　　Try salty dumplings for the Lantern Festival.

　　In addition, the traditional dumpling stuffing is sweet, and nutrition experts also suggest that it can also be made salty, and the stuffing can be freely matched, such as celery, shrimp, hairy chestnuts, pine nuts and black sesame seeds. The traditional dumpling skin is glutinous rice. Now we might as well make a mash-up of glutinous rice to make a coarse grain skin, such as pumpkin glutinous rice and purple potato glutinous rice. We can also freely add various vegetable juices, such as spinach juice, celery juice juice and carrot juice, to the glutinous rice, which is rich in nutrition and has a special taste. At the same time, you can also work hard in cooking the soup of Yuanxiao. You may wish to make the soup of Yuanxiao into tomato soup and vegetable seedling soup, which is balanced and nutritious and delicious.

　　On the morning of 19th, Beijing time, the 2023 Snooker Champions League (ranking match) ended the competition for the second match day of the second stage. All three China players who played on that day were defeated, and no one advanced to the quarter-finals.

　　The ongoing Champions League in Britain is the first ranking match of snooker in the new season. The competition is divided into three stages: in the first stage, 128 players are divided into 32 groups for single round robin, and each group is the first to advance to the top 32; The 32 players in the second stage were divided into 8 groups, and each group advanced to the top 8 first; The eight players in the third stage were divided into two groups, and the top of the group advanced to the final.

　　A total of 19 China players appeared in the first stage of this competition (Ding Junhui, the first brother of China billiards, did not sign up for the competition), and 7 of them advanced to the top 32. On the second match day of the second stage, Si Jiahui, Pang Junxu and Liu Hongyu of Group C, who were in the same group, played on the same day, but all ended up in the second stage.

　　In Group H, TOP16 (the top 16 in the world) star Milkins is the favourite to be promoted, but in the first two group matches, Sijiahui, who just celebrated his 21st birthday, is evenly matched with Milkins (1 win and 1 draw): in the first game, Sijiahui won the "China Derby" with Pang Junxu by 3:1, and Milkins defeated English player astley by 3:0; The two men drew 2-2 in the second match.

　　In the final battle to decide "life and death", as the biggest "dark horse" in this year’s World Snooker Championships, Si Jiahui unexpectedly lost to astley by 1:3.

British player Chris Wakelin won the first place in the group with 2 wins and 1 draw, and grabbed another place in the quarter-finals that day.

　　So far, in 2023, the snooker Champions League (ranking match) has finished four group matches in the second stage, and correspondingly, four places have been promoted to the top eight.

　　On the next match day, China’s Zhou Yuelong and Xiao Guodong, who are in Group A, will both appear. In the second phase of the eight groups, the overall strength of Group A is relatively weak, and Zhou Yuelong and Xiao Guodong’s "double"",is considered to be the most likely to occupy a top eight seats for China legion.

Nowadays, more and more office workers want to use their spare time to improve their academic qualifications without delaying their work. However, the free learning style of self-study exam attracts more and more office workers, and there will be various problems when they first come into contact with it. So how to choose the major of self-study exam?

Click to enter:If you have any questions about the self-study exam, don’t know how to choose the main examination institution and major, and don’t know the local policy of self-study exam, click to learn now > >

You should consider your own interests and hobbies when choosing a major. Only when you are interested in something will you really devote yourself to learning.

You should choose a major that is suitable for your own cultural foundation to ensure the smooth progress of your study. For example, if you have a good mathematical foundation and flexible logical thinking, you can consider choosing a major in science and engineering; If you have a good memory, you can choose a major with strong memory.

We should give full consideration to the needs of society and the development of this industry, and choose some majors whose supply exceeds demand in society, which will have an impact on job hunting and employment in the future.

When choosing a major, freshmen in the self-study exam should not blindly choose a popular major, because the popular major may not be suitable for them. It is suggested that they should combine their hobbies, career planning and their own learning foundation to choose.

1. People who want to improve themselves

With the increasingly fierce social competition, many students or on-the-job personnel will always strive to improve themselves and acquire other skills outside their own majors and industries. However, due to work reasons, there is little time to study. At this time, self-study exam is a very good choice.

2. People who want to take the civil service exam

The gold content of the provincial self-study exam is also the reason that affects their choice of self-study exam. Simply put, the self-taught examination is suitable for most people, and it is beneficial to have a bachelor’s degree to enter a certain industry and take the civil service examination.

3. People who want to select professional titles

Many industries have requirements for employees’ academic qualifications, so improving themselves to adapt to society has become the basis for many people to find jobs. In the workplace, education is a stepping stone. If you want to get more employment opportunities and improve yourself, you can make yourself more recognized.

The conditions for self-taught examination are relaxed, and anyone who wants to improve himself can participate, without considering whether he is suitable for self-taught examination.

The above is related to the adult self-study exam, and candidates can use it as a reference, which is subject to the official announcement!

Summary of Registration Time and Entrance of Self-taught Exams in April 2024 by Provinces

　　Xi ‘an, Central Broadcasting Network, July 22 (Reporter Ren Mengyan) According to the report of the Voice of China of the Central Radio and Television General Station, people in Xi ‘an, Shaanxi Province recently reported to the Voice of China of the Central Radio and Television General Station that their houses were demolished for 10 years due to the construction of Daming Palace Ruins Park and the renovation of shanty towns, and they lived in resettlement houses for 5 years, but so far they have not obtained the real estate license of resettlement houses.

　　Recently, the reporter followed the people who reflected the problem and experienced a complete work flow. He wanted to find out which department was in charge of this business, and could you give a timetable to explain when the real estate license could be obtained, but in the whole process, it was kicked back and forth like a "ball" by various departments. Finally, it was easy to find the responsible institution, but the answer was still "wait". Why can’t you get the real estate license after many years of relocation? Let the masses run back and forth between several departments and ask repeatedly, which link has gone wrong?

　　In 2008, due to the construction of Daming Palace Ruins Park, the bungalow of Li Dajie’s house in Xincheng District of Xi ‘an was demolished. Since 2014, hundreds of households, including Sister Li, have been resettled in Zhujiang New Town, Bafu Manor and Xiangheju. After living in the house for four or five years, I haven’t got the real estate license, so I can’t sell the house for lack of money. When the old man dies, I can only leave a "relocation certificate" for my children, and report it to the 12345 hotline of Xi’ an Municipal Government. After many feedbacks, I still can’t find the responsible department. Sister Li said: "On July 1, 2008, we started to mobilize the demolition. We were the first to sign the agreement in response to the call of the government. At that time, they promised to resettle in five years and issue real estate licenses at the same time. We were resettled in August 2014. At first, I called 12345. Later, the Real Estate Administration called me back, saying that the mortgage certificate of our community had not been completed and asked me to find a relocation office. He said that their place has now been changed into a resettlement office. At the hottest time in June, I ran around and ran five or six places, and there was no place to solve it. "

　　Mr. Lu, who moved to Xiangheju Community, accepted the relocation after Sister Li. He also failed to get the real estate license for many years, called the 12345 hotline and beat around the bush among various departments. Mr. Lu said: "People’s hotline sent a bill to the office left by the city reform first, saying that after the registration of the big card, we need to go to the unit that demolished us at that time, and then we went to the relocation office of the Xi’ an city reform office. They said that this belongs to the new city reform office. On that day, I went to the New Urban Reform Office and asked their leaders. Their leaders said that this belongs to the New Urban Construction Bureau and they are pushing it. "

　　The reporter, together with several resettlement people, went to these relevant functional departments according to the suggested process, hoping to see where the source of not getting the real estate license is, when there will be progress, and whether you can give an accurate statement. The new urban demolition office, which was responsible for demolition in those days, is now a resettlement office. Director Niu, the person in charge, said that the experience of these relocated households is not a case.

　　Director Niu: There is no formal certificate for all of them, including Zhujiang New Town.

　　Resident: We are from Zhujiang New Town.

　　Director Niu: There are no certificates, and there are Bafu Manor, Xiangheju and Taiheju. I am exactly like you. I have been demolished for more than ten years. I was informed that I should apply for a permit a few years ago and asked me to get all the information I should hand in. I haven’t heard from you yet.

　　Resident: We can’t wait forever!

　　Director Niu: So we can’t say this. This is the coordination between the city and the city reform office, and it is solved piece by piece. This is a historical problem left over from Xi ‘an.

　　When the demolition department couldn’t help, it went to the new urban housing and construction bureau. After learning about the problems reflected by the masses, the office staff said that they should go to the shantytown renovation office in the new city. "This is a project for the reform of the new urban area. This matter should be solved by the urban reform office."

　　Rushed to the new city shed to do, a staff member told everyone that you should go to the developer to do the real estate license.

　　The staff of the shed reform office: all the real estate licenses are developers.

　　Sister Li: Where did the developer say the demolition was? Who are you looking for?

　　Staff of the shed reform office: This is not a push. It takes a lot of procedures to apply for a real estate license. It can only be declared after the acceptance procedures are completed. We also cooperate with the developer’s work in handling the real estate license. When people apply for a permit, we will provide your original real estate license and demolition agreement to others, who will do it. We have other projects, and we just do this work.

　　However, the staff of the developer of Zhujiang New Town said that their initial registration of the real estate license "big certificate" has been handled, and they have fulfilled their obligations. As for the personal real estate license for the masses, they should not handle it, and they should find the department responsible for housing distribution.

　　Developer: Who will give you the house? My developer is only responsible for the big card, and now it has been done.

　　Sister Li: Then who shall I go to?

　　Developer: I won’t tell you, who will give you the house?

　　Another staff member said that they didn’t understand the situation of Zhujiang New Town, Xiangheju and other communities, and it was not handled by their department. However, it is indeed their responsibility to reflect that there is no property right certificate in Bafu Manor Community. Although the resettlement house of Bafu Manor has been built for many years, the most basic land procedures have not been completed, which leads to the failure to complete the most important "five certificates" in real estate development, and naturally it is impossible to provide real estate licenses for the masses.

　　Staff of the new urban shed reform office: Bafuzhuang is in our charge, and it has not got the land certificate now, so we can’t handle it later.

　　Reporter: How can we build a house without a land certificate?

　　Staff of the new urban shed reform office: That’s the problem of villagers’ land confirmation. We can finally coordinate it now. Now we start to apply for land certificates. There are some things to be accepted before we apply for land certificates. You can only make the final land certificates after you get the completion acceptance report. After you get the land certificates, you can only do these big certificates (real estate licenses).

　　The answer given by the owners of Bafu Manor Community is "Wait". What should the owners of Zhujiang New Town and Xiangheju do? When I went to the shantytown renovation office in Xi ‘an, the staff gave the owner of Xiangheju a statement, saying that the procedure was going, or it had to wait. As for the owners of Zhujiang New Town, they should go to the Daming Palace Site Protection Office. The staff of Xi ‘an Shed Renovation Office said: "This was demolished by the Construction Bureau. After the demolition, it was placed in Xiangheju. Its big card has been obtained, but there are still four buildings that have not been obtained, but it will be soon."

　　Finally, after running 47 kilometers back and forth in Xi ‘an, the owner of Zhujiang New Town found a statement in the Daming Palace Site Protection Office. The staff said that they are responsible for this matter, but the real estate license will have to wait. Because the Pearl River New Town and the Taiheju Community next to them were built with affordable housing, before the demolition, the owners lived in ordinary houses, and they have been stuck in how to turn the real estate license of affordable housing into the real estate license of ordinary commercial housing. The staff of the Daming Palace Site Protection Office said: "If you directly give everyone a small certificate for demolition and resettlement houses, the Pearl River can also follow this process. The situation is that we are still coordinating to see if we can change the nature of the house and directly turn it into a demolition and resettlement house. Affordable housing can certainly be done, but it is not the same as everyone’s requirements and can’t be traded. Therefore, it is conservatively estimated that it will be next September. "

　　The resettlement houses in Zhujiang New Town, Bafu Manor and Xiangheju have not been able to obtain real estate licenses for many years, and some even have no basic land certificates. It has been reflected for so many years. How long will it take to wait? Voice of China, CCTV, will continue to pay attention.

When considering skiing equipment, its importance is self-evident. Appropriate and comfortable skiing clothes and equipment are very important for mastering skiing skills, especially for beginners. Although buying a complete set of equipment may be an option, in fact, most of the equipment can be rented from the snow field.

1. Helmets and ski goggles

When attending ski courses, helmets are usually available, so for beginners, it doesn’t matter even if they don’t prepare themselves. Ski goggles don’t need too much attention, as long as they can effectively block the sun.

Step 2: gloves

In the choice of ski gloves, waterproof gloves are strongly recommended if you want to experience the fun of skiing in depth. Good glove design includes long-sleeved gloves and "two in one""Gloves, the former can prevent snow water from infiltrating into gloves, while the latter has both warm and waterproof properties.

3. Ski pants

Ski pants are also recommended to be made of waterproof material, and it is best to have elastic bands at the bottoms to firmly fix the pants outside the ski boots.

4. Ski coat

As for ski jackets, a pair of waterproof ski pants is enough for beginners. Although the down coat is not completely waterproof, it is still necessary to be cautious when skiing in snowy weather.

5.snowshoes

Snowshoes are the core equipment of skiing, and their size is very important. Suitable snowshoes should make your toes lightly touch the toe.

6. Snowboards and poles

For beginners, skis and poles can be rented from ski resorts. When choosing a snow pole, you should take your height as the basis, the longest one should not exceed your shoulders and the shortest one should not be below your ribs. Beginners can choose a longer pole.

　　Cctv news(Reporter Li Wenxue) Since the beginning of summer, three roads around the Harbin municipal government have been sunburned to varying degrees, especially the World Trade Avenue, which is the main trunk road in Songbei District. For this situation that has never happened before, the Songbei District Urban Management Bureau said that it was found that the asphalt ductility was low, and the construction unit and supervision unit were punished and ordered to clean the contaminated cars and clothes free of charge.

Suntanned asphalt polluted the street.

　　On May 19th, the weather forecast showed that the highest temperature in Harbin was 27 degrees Celsius. At 13 o’clock, the reporter found on both sides of the World Trade Avenue that nearly a thousand cracks in the nearly 2-kilometer section of the road were sunburned, and after being crushed by cars, they became a black piece, distributed on the road, shining in the sun. From a distance, it looks like there are many places of water, emitting an unpleasant smell.

The tire was stuck with asphalt and stones.

　　Pedestrians feel sticky when passing through these sections, while vehicles make a continuous "click" sound when passing by. Bitumen tire tracks can be clearly seen on roads and sidewalks, and asphalt and stones are also stuck on the tires of vehicles parked nearby.

　　Songbei District, named after its location on the north bank of Songhua River, was established in 2004. It is an administrative development zone, a national-level ecological city, the core bearing area of the national "Harbin New District", the seat of Harbin Municipal Government, and a national-level high-tech zone — — Harbin High-tech Zone implements unified management.

　　On many main roads in this area, frost heaving, shrinkage and cracking of pavement caused by temperature can be seen everywhere. Cracks covered with asphalt, like newly healed "scars", do not match the appearance of the new area very well.

　　On May 29th, Dong Xuanli, the person in charge of roads and bridges in Songbei City Administration Bureau, said in an interview with CCTV reporter that due to the limited funds, they did not rip off the pavement resurfacing, but poured hot asphalt on the pavement cracks on May 8th, but on the second day of pouring, that is, on May 9th, the asphalt was sunburned, which appeared again on the 19th. "This has never happened before."

　　The reporter inquired that the highest temperature in Harbin on May 9 was only 21 degrees Celsius.

Pedestrians crossing the street should jump out of the place where the asphalt melts.

Footprints covered with asphalt on the sidewalk

　　Dong Xuanli said that during this period, the Urban Management Bureau received more than 40 complaints from the masses. In addition to the World Trade Avenue, it was also found that the caulking asphalt in Tianyuan Street and Tian Xiang Street also showed signs of melting and was run over by passing vehicles. They immediately asked the construction unit and supervision unit to stop the construction, take measures such as sprinkling water and embedding sand stones to treat the pavement, and sample the asphalt used in the construction for inspection.

The phenomenon of asphalt melting can be seen everywhere

　　The test results show that the ductility of this batch of asphalt is low, which leads to slow setting of asphalt and low melting point to pollute the pavement. Therefore, Songbei Urban Management Bureau decided to impose a fine of 4% of the project cost (more than 900,000 yuan) on Heilongjiang Yufeng Road and Bridge Construction Group Co., Ltd. and Heilongjiang Zhongwei Construction Engineering Supervision Co., Ltd.

　　At the same time, the Songbei Urban Management Bureau also ordered the construction unit to clean the defiled vehicles and clothes free of charge, and apologized for the inconvenience and influence caused by this incident to the general public.

　　"We asked the construction unit to change the supplier and re-inject the pavement cracks. We also monitor these roads at any time, and now there is no problem. " Dong Xuanli said.

　　However, the situation is not as optimistic as Dong Xuanli said.

Construction workers are spreading sand on the road.

　　On May 31st, the highest temperature in Harbin was 31 degrees Celsius. At 15 o’clock, the reporter visited the World Trade Avenue and found that the construction workers were sprinkling sand on the road surface, and the phenomenon of asphalt melting was still serious. Pedestrians needed to jump when crossing the street.

　　In the next few days, Harbin will have a high temperature of 37 degrees Celsius, and the ground temperature will be higher. I hope the relevant departments will really pay attention to this problem and effectively solve this travel problem.
