Original title: Many physical examinations are to deal with things! These most unreliable physical examination items, don’t be pitted again!

Why is the annual physical examination, the indicators are "normal", but suddenly cancer is detected? Is it still late when it is found out?

Speaking of physical examination, many people have the following feelings:

1。 "The detection process is not rigorous, and the disease cannot be detected."

2。 "there are many medical examination packages and the fees are chaotic."

3。 "Some medical institutions are like lanterns. After checking for a long time, they will be psychologically comforted."

Yes, even an internal staff member of a large medical examination institution revealed that "medical examination is a matter of ignorance"!

Moreover, the medical examination fee is not a small expense. A slightly comprehensive inspection package will cost three or four thousand yuan, and the price will easily be "over 10,000" by adding several inspections!

Doctor: Many physical examinations are just a matter of coping with things.

Bi Xiaofeng, deputy director of the Department of Cancer Prevention, Cancer Hospital, China Academy of Medical Sciences, said: In fact, physical examination in many units is easy to become a mere formality, and there is no key direction at all, which is a waste of money and can’t help to check diseases, especially many serious diseases. ①

Physical examination refers to the physical examination of normal people. It is meaningful to be accurate, in place and even critical. For example, screening early rectal cancer by anal digital examination is basically the same as drinking water to satisfy hunger, and it has no practical significance. ①

To this end, Xiao Bian specially counted the "most unreliable" medical examination items. If you encounter a medical examination in the future, don’t do it again, it’s a waste of money!

Inventory: the most unreliable physical examination project!

Color Doppler ultrasound examination of prostate

One of many physical examinations is abdominal color Doppler ultrasound, and men over 40 years old often add an extra item called "Qiancai"-prostate color Doppler ultrasound to screen whether they have prostate cancer.

This test can’t detect early prostate cancer, and it doesn’t even have the effect of diagnosis. There is really no way to identify whether it is benign hyperplasia or prostate cancer by color Doppler ultrasound. This can’t be distinguished, because the manifestations of cancer are the same when detected by color Doppler ultrasound. Whether the patient’s nodules are inflammatory or proliferative nodules can’t be distinguished from color Doppler ultrasound or B ultrasound.

[Correct examination method] If you really want to tell whether it is prostate cancer or not, MRI should be the first choice, and the cost is relatively high. An MRI costs a total of one or two thousand yuan, which is completely unnecessary in the ordinary daily physical examination package. When middle-aged and elderly men need to be screened for prostate cancer, the best examination is prostate-specific antigen project, which is what we call "PSA examination". ②

2 blood calcium examination

In the package of general medical examination center, whether it is the package for the elderly or the package for children’s medical examination, there will be an examination called blood calcium examination. Blood calcium test is to measure trace elements by drawing blood to judge whether there is calcium deficiency, especially for children. Many parents are also particularly concerned about this item. In fact, it is completely unreliable.

According to the doctor, trace elements should not be used as a routine physical examination or an item that needs to be examined. Its accuracy is definitely not as high as that of spot check and examination from venous blood. After finding out (there is a problem), it is forbidden to judge whether he is really deficient in zinc, calcium or iron based on such a laboratory test. The calcium in trace elements refers to the whole calcium. When it is really deficient in calcium, it should be deficient in permanent calcium.

As early as five years ago, in 2013, the former General Office of the National Health and Family Planning Commission issued a notice on the clinical detection of trace elements in children: the detection of trace elements should not be used as a routine physical examination item!

It is also emphasized that medical institutions at all levels should not carry out trace element testing for children unless it is necessary for diagnosis and treatment. Trace element detection should not be taken as a general survey item such as physical examination, especially for infants under 6 months. ③

That is to say, it is illegal to test trace elements during general physical examination and medical treatment! It is clearly stated in the document of the National Health and Family Planning Commission that medical institutions that carry out trace element testing in violation of regulations should be dealt with according to the law!

It is even more nonsense to check blood calcium by drawing blood. This kind of inspection is mostly for the purpose of re-checking and selling calcium tablets to you.

3 cervical curettage screening

In the packages of many medical institutions, there will be an examination for women in their 30 s and 40 s called cervical curettage screening. I often tell you that this test is for cervical cancer.

However, the doctor said that the average satisfaction rate of cervical smear sampling is only 60%, which means that 40% of the inspection samples are unreliable, so the pathologist can’t be blamed for missing diagnosis. Therefore, this inspection must not be done, even if it is done, it will not be found!

[Correct examination method] The most recommended item for screening cervical cancer is ——TCT. The upgrading of technology has improved the sampling satisfaction to over 95%, and those suspicious cancer cells will be difficult to hide! Who needs special attention: married, have found cervical abnormalities, have not checked TCT for three years, and have reproductive tract symptoms. ②

4 creatinine/urea nitrogen check

Generally, in the urine biochemical examination, some medical institutions often recommend you to add a "creatinine/urea nitrogen examination" and tell you that this examination is to check "kidney function".

According to the doctor, even if you lose half of your renal function, you can still survive, and creatinine/urea nitrogen may still be normal. Real kidney damage is often recessive and chronic, and the early damage is not corrected. When there are symptoms or creatinine/urea nitrogen exceeds the standard, you can’t go back! In other words, even if the "creatinine/urea nitrogen test" shows that you have a problem, it will be late!

[Correct examination method] The correct examination to check whether the renal function is normal should be urinary microalbumin-as long as there is a little glomerular damage, albumin may "leak" into the urine, and microalbumin can be accurately detected, so the early renal damage can’t be hidden. It is better to reduce the error caused by urine concentration by detecting the ratio of microalbumin to creatinine in urine, so it is called early renal function screening (ACR).

5 cervical lateral radiograph examination

As we all know, many medical institutions will add a cervical lateral film examination to the medical examination package to help you check whether there is cervical spondylosis.

However, the lateral radiograph of cervical spine can only look at whether there is any abnormality in curvature, and occasionally disc herniation can be found, and a "degeneration" that is meaningless is reported; The dislocation of cervical spine is not only anteroposterior, but also left and right, rotation and other angles, and the influence on cerebral blood supply and nerve root compression needs to be considered. The most important thing is that cervical radiographs not only have little effect, but also inevitably radiate to the most delicate and important organ of the human body-thyroid! You should know how common thyroid problems are.

[Correct examination method] The correct examination should be to go to the hospital to check the cervical MRI-nuclear magnetic resonance can reconstruct the images of cervical vertebrae and intervertebral discs in three dimensions, and there is no radiation concern at all. If combined with the physiological examination of cervical vertebra, it can comprehensively detect the early joint dislocation and dysfunction of cervical vertebra, and help to directly guide rehabilitation.

6 fasting blood glucose screening for diabetes

Many medical institutions will tell you in advance that you should never eat before the medical examination, because blood is drawn to check your blood sugar and check whether you have diabetes.

According to authoritative research, fasting blood glucose screening will miss nearly half of diabetes and more than 70% of pre-diabetes, and at least half of them have disorder of blood glucose metabolism (or diabetes trend), so it can be said that fasting blood glucose screening for diabetes is the most unreliable physical examination item!

[Correct examination method] The correct examination should be to check glycosylated hemoglobin, which can reflect the average blood sugar level for three months and greatly reduce the missed diagnosis caused by fasting blood sugar alone; Early diabetes screening is recommended, which can detect the physiological disorder of blood sugar/insulin at an early stage, and it is the most suitable early warning method for diabetes in general survey without blood drawing and needle puncture.

The first few items of physical examination generally have the measurement of "height and weight". Many people have finished the examination, and often the results appear last time-obesity and overweight.

In fact, judging whether you are obese by your body weight is not so accurate. This is because the formula for judging obesity is the conversion formula of BMI.

Body mass index formula (BMI)= weight (kg) height 2 (m)

However, there are many "hidden fat people" who are not fat but have high fat content; There are also super-fit people, who weigh off the charts but have a perfect figure, but of course they are not obese. ②

[Correct inspection method] Experts remind that the standard of body composition analysis-whether it is obesity is definitely the body fat rate, not the height-weight ratio. Therefore, we can’t fully believe the "obesity and overweight" in the physical examination report.

No gastric cancer can be found in 8 laboratory indexes.

Laboratory indicators include hematocrit, hemoglobin, fecal occult blood, gastric juice and many other items, which are often used to indicate the health of the stomach in physical examination, but in fact, gastric cancer can not be detected.

It’s ok to use laboratory test indexes in the primary screening of gastric diseases, but if we use these indexes to screen gastric cancer, it’s a bit overwhelming, because their accuracy is still not up to the requirements.

[Correct examination method] Experts suggest that gastroscopy is the most standard and accurate, and it is the first choice for screening and diagnosing gastric cancer. However, gastroscopy is relatively expensive and more painful, and it is an invasive examination. Therefore, if the result of the first gastroscopy is benign, it can be done every five years. However, if the physical examination results show that there are patients with gastric dysplasia (such as inflammation), atrophy, gastric ulcer or family history of gastric cancer, besides treating these diseases, the interval of physical examination is preferably 2~3 years.

Finally, after reading this article, pass it on to your family.

Don’t waste money on the next physical examination!

Hualong Net News (Yuyang) Barrier-free access is related to citizens’ travel and reflects the humanistic care of the city. On June 1, netizen Ms. Zhou was at Hualong. com.Chongqing network politics platformPosting reflects that there is no barrier-free access at the intersection between Agile Community and Aiyushan Community in dadukou district, and it is inconvenient for children’s carts and old people’s wheelchairs to travel. It is suggested to rectify.After the linkage of the political platform, on June 11, the dadukou district Urban Management Bureau completed the rectification, further facilitating the citizens’ travel..

Netizen: It is suggested to set up barrier-free access here to travel smoothly.

Ms. Zhou told Hualong. comChongqing network politics platformShe lives in Shuangcheng Road, dadukou district. There is a traffic light intersection between Agile Community Phase I and Aiyushan Community, and there is no barrier-free access on both sides of the road. It is very inconvenient for children’s wheelbarrows and old people’s wheelchairs to cross the street from here.

"Trolleys and wheelchairs need to be carried up and down when crossing the road, which is very inconvenient. The traffic lights are short and there are certain security risks. " Ms. Zhou said that she hopes that this intersection will be barrier-free and convenient for citizens to travel.

Dadukou district Urban Management Bureau: Renovation in the near future.

After receiving feedback from netizens, Hualong. comChongqing network politics platformActively linked with dadukou district. On June 8th, dadukou district City Administration Bureau replied:

After on-site verification by the staff of our bureau, it is confirmed that the traffic light sidewalk between Agile Community and Aiyushan Community has not yet built barrier-free access. In this case,Our bureau has carried out detailed planning and formulated the corresponding transformation plan.. At present, we are actively preparing andIt is planned to carry out the renovation project of barrier-free access to the sidewalk in the near future to ensure the smooth passage of citizens..

Progress: barrier-free transformation has been carried out and the blind road has been penetrated.

On the morning of June 12, the political platform called back to Ms. Zhou, a netizen. She said happily that the urban management bureau had called her and told her that the site had been rectified and barrier-free access had been built.
　

Subsequently, the political platform contacted the dadukou district Urban Management Bureau by telephone.

Yang Jun, a staff member of the Bureau’s Road and Bridge Department, said that after receiving a complaint from the political platform that "there is no barrier-free passage on the sidewalk near Agile Community in Dadukou",Dadukou district Urban Management Bureau attached great importance to it and acted quickly. It immediately contacted the complainant to go to the site to implement the situation, and immediately formulated a barrier-free passage reconstruction plan, which entered the site on June 5 and was completed on June 11. And the barrier-free passage at the intersection will be connected with the blind road on the sidewalk to further smooth the travel of citizens..

Good voice: Netizens expressed their gratitude to the political platform and the dadukou district Urban Management Bureau.

The political platform understands that Ms. Zhou has gone out on vacation and is not in dadukou district. When she received a phone call from the urban management bureau, she contacted her neighbors to take pictures on the spot in order to share her joy.
　

Ms. Zhou gave it back to Hualong. comChongqing network politics platformSend a thank you. She said,I am very grateful to the political platform and the dadukou district Urban Management Bureau for their attention to barrier-free facilities, actively planning and transforming them, ensuring the smooth passage of citizens and making them feel the concern and warmth of the government.

　　It sounds normal to get older, love cleanliness and can’t stand noise? However, if noise really makes middle-aged and elderly people feel flustered and chest tightness, it may be a signal from coronary heart disease! There are still many imperceptible signals in life, all of which are that the heart is "calling for &hellip", such as chest pain when nervous, palpitation when eating too much, need a high pillow when sleeping, and suddenly have difficulty breathing when lying down. …

　　On July 29th, the ninth issue of Lingnan Chinese Medicine Popularization Forum was held in Sin Nui Hung’s former residence, where the traditional cultural charm was strong. Professor Wei Wu, the academic successor of Deng Tietao, a master of Chinese medicine, and the director of the Department of Internal Medicine of the First Affiliated Hospital of Guangzhou University of Chinese Medicine, shared his exclusive experience in preventing and treating coronary heart disease and daily aftercare with integrated traditional Chinese and western medicine.

　　Professor Wei Wu reminded that at present, patients with cardiovascular diseases will be more "difficult" when the temperature continues to be high, often in the extremely cold and hot climate. Everyone should take care of themselves.

　　What are the risk factors of coronary heart disease?

　　Coronary heart disease (coronary atherosclerotic heart disease) usually refers to the heart disease caused by coronary artery stenosis or obstruction, resulting in myocardial ischemia, hypoxia or necrosis, which may be clinically manifested as asymptomatic myocardial ischemia (occult coronary heart disease), angina pectoris, myocardial infarction, ischemic heart failure and even sudden death.

　　Wei Wu said that the process of atherosclerosis is very slow, and all types of coronary heart disease may have no symptoms in the early stage, so we should pay attention to early detection methods. In essence, arteriosclerosis is a kind of vascular aging. What people can do is to delay the aging process as much as possible and avoid all kinds of unhealthy life behaviors that lead to accelerated vascular aging. Therefore, Chinese medicine advocates health preservation, starting from adolescence.

　　So, what are the risk factors of coronary heart disease in medicine?

　　Wei Wu said that uncontrollable risk factors include age, sex (the prevalence rate of male patients is higher) and heredity, while controllable factors include hypertension, hyperlipidemia, smoking, diabetes, obesity, stress, unhealthy diet and lack of exercise. The most common factors can be summarized as "four highs and one smoking": hyperlipidemia (dyslipidemia), hypertension, hyperglycemia (diabetes), high weight (obesity) and smoking.

　　If you are related to any one or more of these factors, for example, you are a middle-aged man with high work pressure and smoking, and the data in the annual physical examination report are not ideal … … Then pay special attention to the signals sent by the heart.

　　What "signals" suggest coronary heart disease?

　　Occasionally, when you are tired, you are flustered and breathless during exercise. It may not be a thing, and many people will not care. But superimposed risk factors, the following details, you may want to pay attention to — —

　　1. When mental stress occurs, there is stuffy pain in the posterior sternum or precordial region, or constrictive pain, which radiates to the left shoulder and left upper arm for 3-5 minutes, and then relieves itself after rest.

　　2. Chest tightness, palpitation and shortness of breath occur during physical activity, and they will relieve themselves at rest.

　　3. Headache, toothache and epigastric pain related to sports.

　　4. Chest pain and palpitations occur when you are full, cold or watching thrillers.

　　5. When you sleep with a low pillow at night, you feel chest tightness and breathlessness, and you need a high pillow to feel comfortable; Sudden chest pain, palpitation and dyspnea while sleeping or lying flat during the day can be relieved only by sitting up or standing up immediately.

　　6. Palpitation, chest tightness, shortness of breath or chest pain occur when defecating hard or having a hard sex life.

　　7. Hearing the sound of gongs and drums or other noises around will cause palpitation and chest tightness.

　　8. Repeated irregular pulse, tachycardia or bradycardia for unknown reasons. Especially with dizziness and transient fainting.

　　Chest pain "dangerous moment" should not be careless

　　Wei Wu said that if physical strength drops suddenly within a period of time, it may be a symptom of chronic and stable coronary heart disease; The other situation is also relatively slow, which will be manifested as ischemic cardiomyopathy, heart failure and arrhythmia. You should go to the hospital for examination as soon as possible.

　　In particular, people with risk factors for coronary heart disease, if the symptoms of chest pain are not relieved for more than 15 minutes, are likely to have an acute infarction. They must call the emergency number for help and try not to drive or take a bus to the hospital. This kind of pain is generally accompanied by oppression, squeezing pain, congestion and urgency, which can radiate to fingertips and toes.

　　Some manual workers have developed tolerance and may not be sensitive to these pains, and the elderly, diabetics who are insensitive to peripheral nerves, etc. may also be insensitive to pain, which will amplify the danger. We must be aware of prevention and not be careless.

　　Correct exercise and diet intervention can prevent coronary heart disease

　　Exercise intervention

　　It is recommended to do 30 minutes of exercise every day for at least 5 days a week. Exercise intensity is controlled at: the maximum heart rate per minute =180- years, or the maximum heart rate does not exceed 60% of the normal heartbeat. The best exercise can achieve the effect that aerobic exercise perspires slightly and you don’t feel tired the next day.

　　Exercise suitable for middle-aged and elderly people to prevent diseases includes walking, jogging, slow cycling, playing Tai Ji Chuan, and doing Baduanjin.

　　If you are already a patient with coronary heart disease, you should pay attention to exercise: avoid emotional excitement before and after exercise; It is not advisable to have a full meal before exercise; Exercise should be gradual, and don’t suddenly engage in strenuous exercise; Carry first-aid drugs for coronary heart disease during exercise.

　　Dietary intervention

　　To prevent coronary heart disease, Chinese medicine pays attention to avoiding fat, sweet and thick taste, and suggests balanced+light+nutrition+total calorie control in diet, choosing a healthy diet containing a variety of fruits, vegetables, grains, low-fat or fat-free foods, beans, fish, poultry and lean meat, controlling salt intake and not drinking alcohol.

　　Reasonable diet can keep in mind the principle of "1234567": a bag of milk or soy milk every day; Two or two staple foods per meal, six or two per day; Three servings of high-protein food every day (1 liang lean meat, or half liang soybeans, or 2 liang tofu, or 1 egg, etc.). Four sentences: coarse and fine, not sweet or salty, three or four or five meals, seven or eight full; 500 grams (1 kg) of fresh vegetables and fruits every day, preferably green, red and yellow vegetables; The daily intake of salt should be 6 grams; Drink seven glasses of water (200ml a cup) every day.

　　Foods that can be eaten at will: grains, especially coarse grains; Beans, especially soybeans and their products; Vegetables, especially onions and garlic; Bacterial algae, such as mushrooms, fungus, kelp, laver, etc.; All kinds of melons, fruits and tea.

　　Foods that can be eaten properly: lean meat, including lean pork, beef and poultry (peeled); Fish, including most river fish and marine fish; Vegetable oil, including soybean oil, rapeseed oil, corn oil, sesame oil, etc. Milk, such as milk, goat milk, etc. Eggs, 2-3 per week, people with hypercholesterolemia should eat as little as possible.

　　Foods that you eat less or avoid: animal fats, such as lard, butter, sheep oil, chicken oil, cream, etc. Fat meat, including pigs, cattle and mutton; Brain, spinal cord, viscera; Egg yolk and roe; Mollusk and shellfish; Tobacco, wine, sugar, chocolate, etc.

　　Traditional Chinese medicine medicated diet nursed back to health: ginseng, codonopsis pilosula, astragalus, salvia miltiorrhiza, Polygonum multiflorum, hawthorn, Ophiopogon japonicus, motherwort, notoginseng, ganoderma lucidum, pueraria lobata, Taxilli and ginkgo leaves.

　　Since 1976, he began to study high critical temperature superconductors, and his name has always been closely related to superconductivity for half a century.

　　As one of the pioneers who started the research of high-temperature superconductivity in China, he first proposed to explore high-temperature superconductors in China, and first proposed to set up a national superconducting laboratory … … It has made indelible contributions to China’s superconducting development from starting, catching up and being among the forefront of the world when it is 50 years behind.

　　In the history of superconductivity research for more than a hundred years, there have been two major breakthroughs in high-temperature superconductivity. He and his collaborators have made important achievements, namely, independently discovering high-temperature superconductors in liquid nitrogen temperature region and discovering a series of iron-based high-temperature superconductors above 50K and creating a record of 55 K.

　　Today, science and technology have a profound impact on the country’s future and destiny. In the field of high-temperature superconductivity, he and his team are constantly attracting groups of young people and pushing China’s high-temperature superconductivity research to the forefront of the world.

　　He said, "The core science and technology can only be done by ourselves. It is necessary to combine personal interests with the destiny of the country, cooperate in tackling key problems, and serve the country. "

　　He said, "I would like to be a paving stone and let young friends make great achievements."

　　He is the winner of the highest national science and technology award in China in 2016, academician of China Academy of Sciences and physicist Zhao Zhongxian.

　　Sidenote 1: When an old superconducting expert meets an old director of the compilation bureau.

　　There are four old people among the guests who participated in the recording of "Example" this time. Apart from the special guest Mr. Niu Benlao and a veteran member of the National Survey Team, Mr. Yu Qiqing, who was the first to take part in the Everest survey in China, he is the former director of the Central Compilation Bureau, Mr. Song Shusheng, and academician Zhao Zhongxian, a superconducting expert.

　　During the filming, Academician Zhao Zhongxian and Mr. Song Shusheng sat together. One of them leaned back thoughtfully, and the other sat upright and had a straight body. I thought that two doyen in different fields would care for each other and sit together as a pair of quiet handsome men, but there was a special dialogue:

　　"I have read Anti-Turin Theory." Academician Zhao said.

　　"This book is good, it expounds the three components of Marxism, and it is also relatively easy to read … …” Mr. Song Lao also turned around and began to communicate seriously.

　　Compared with HTS, a high-cold scientific research topic, the old academician Zhao Zhongxian himself gives people a much more vivid feeling.

　　He is humorous and honest and frank. From time to time, he uses his loud voice to open the "Tucao" mode, which causes people next to him to laugh. He has a wide range of daily hobbies, and he tries skiing and drifting. Literature, photography, cultural relics in museums and good music in China and the West are all his interests. His heart is firm and soft, with the rigor, strictness and seriousness of scientists, and he always thinks about students and the life and future development of young people.

　　Under his "independent" face, there is warmth, hope, swallows whispering, and flowers blooming from tree to tree.

　　Sidenote 2: "Scientific research is like playing mahjong"

　　When the program was recorded, Academician Zhao Zhongxian was asked: "You have done one thing all your life, and it is something that 99% people in the world don’t understand. How did you persist? " The old gentleman’s spit mode was turned on.

　　"I think many people don’t understand the fun of scientific research, saying that scientific research is a bench and asking me why I can persist for decades. If you like playing mahjong, do you think you can’t stick to it? " The old man said.

　　"Scientific research will encounter such difficulties, but just like people playing mahjong, as long as they are interested, they still want to play if they fail, not to mention that we often draw cards, small and big!"

　　In his mind, the "bench" of scientific research is not always cold. Despite many difficulties, in the process of research, the more you do, the more interested you are. Interest is very important. You are addicted and very willing to do it. At the same time, it is also an encouragement to make new progress in our work. Insisting on doing something has a sublimation of understanding on the basis of long-term accumulation.

　　In a speech, he mentioned how he became interested in science: in 1956, the state proposed "marching into science." As an imaginative and energetic middle school student, he participated in extracurricular activities of the school physics group and read popular science magazines, which led him to like science. He said: Many years later, I gradually realized that understanding science is a kind of enjoyment, which can gain new knowledge, arouse curiosity and enhance interest.

　　He was admitted to China University of Science and Technology in 1959. He said that at that time, many students were willing to study science and engineering, which was the call of the state and very fashionable. Popular majors include atomic bombs, semiconductors, etc. "I remember that the cover of the admissions brochure of the University of Science and Technology of China is the rocket. I think it is this that attracted many students, including me, to apply for China University of Science and Technology. It should be said that the call of the country made many people in our generation choose science and technology. "

　　He said that it is the best choice to combine personal interests with livelihood, and he happened to be very lucky.

　　Sidenote 3: I think it is very important to settle down and do things.

　　In the process of chatting with Mr. Niu Ben, when he mentioned some "short and fast" phenomena in the film industry, Mr. Zhao Zhongxian’s tucao mode was opened again:

　　Now there are so many scientific and technical personnel and teams all over the country. I think it takes a person or a team ten years, or twenty years to solve an important scientific problem or a core technical problem. Does that add up?

　　He said, don’t be eager for quick success, set a long-term goal. "Now these young people have a good foundation, because their education is very complete, their equipment is world-class and their funds are sufficient. I think the current conditions are very good, and the key is to settle down and do things. "

　　He believes that "scientific research is a natural and rising process. You have a group of people who have found the right direction and made unremitting efforts in a down-to-earth manner, and will always make discoveries that are beneficial to the progress of human civilization. " As long as all of us can settle down and concentrate on our work, instead of catching up with the "trend" to do things of the same nature, short-term and quick success, our country’s science and technology will develop faster and better.

　　He said, "I have only done one thing in my life, that is, exploring superconductors and conducting research on superconducting mechanisms. If everyone in our society persists in doing one thing, many problems can be solved. "

　　Sidenote 4: "Academician Zhao speaks the scientific research party class very well."

　　During a chat, Academician Zhao Zhongxian chatted, "I have both Chinese and English versions of The Supreme Leader’s Talks on Governing the Country, and some places in the English version are more clear than the Chinese version."

　　Teacher Dong, the assistant, is sitting on the side. "Academician Zhao speaks the scientific research party class very well."

　　On July 19th, at the China Academy of Sciences’ theme activity of "Patriotism and Dedication, Being the Pioneer of the Times", Academician Zhao Zhongxian was invited to give a special party class to the delegates.

　　He talked about the patriotism, dedication, scholarship and self-cultivation of the older generation of scientists, and that after entering China University of Science and Technology, he was inspired by the knowledge and spirit of the older generation, and gradually changed his love for science when he was young into a sense of responsibility and mission in scientific research.

　　He said that the older generation of scientists taught not only knowledge, but also spirit. In his study and practice, he constantly understood the essence of these famous predecessors’ scholarship, and gradually realized that scientific research needs to take root, and long-term persistence and accumulation will be sublimated in understanding, so as to seize opportunities and accumulate wealth.

　　He said that his 40-year persistence benefited from the stable environment, and he grew up under the inspiration of the spirit of the old Red Army and the patriotic dedication of the older generation of scientists. The most comforting thing is "I gave".

　　He hopes that young friends can settle down and concentrate on their work. "One generation does the work of another generation, and several generations of teachers and students cultivate it to realize the rooting of Chinese science." He also believes that they have the ambition and ability to contribute to building a world-class science and technology power and the progress of human civilization.

　　Sidenote 5: Why can you do one thing all your life?

　　"I have faith and am interested in science."

　　During my brief contact with Academician Zhao Zhongxian, the words "faith" and "interest" impressed me the most. These two words have accompanied his life’s choices and supported his scientific research career for decades.

　　In 1956, the state proposed "marching into science". As an imaginative and energetic middle school student, he took part in extracurricular activities of the school physics group, read popular science magazines, and gradually became fond of science.

　　In 1959, he was admitted to China University of Science and Technology, and listened to the lectures and reports of famous teachers and the relationship between science and technology and the fate of the country. He began to feel that he was not only fond of science, but also had a sense of responsibility and mission.

　　In 1972, China Academy of Sciences won more than 20 places to study abroad, and he was selected to go to Cambridge University in England for further study after applying for superconductivity. He enjoys the experimental work of "nine to ten" and is always full of passion. Seeing the gap in contact with international counterparts, he began to move towards the field of high temperature superconductivity.

　　China, who is in a great hurry, returned to China to lead his team to build their own experimental equipment. The conditions were so hard that he beat mice under the covers. He was still optimistic that his relative disadvantage was not so great. "Compared with other scientific research, the exploration of superconducting materials does not need particularly advanced and complicated instruments. I am willing to make full use of the existing conditions to carry out a project."

　　After decades of high-temperature superconducting research, he felt the regret that he was beaten to the top by one step, and he also experienced the joy of seizing the opportunity when the international competition was the fiercest. I have experienced the frenzied scene of the "Rock Music Festival in Physics" which lasted for more than 7 hours, and I have also been under great pressure to be questioned because of the many achievements of raw materials and impurities used in experimental samples. Or sit on the bench day after day, or add honor to your success. Between ups and downs, his interest remains, his faith remains, and his "initial heart" has never changed.

　　For half a century, he has always been interested in and curious about science as a teenager. "Doing scientific research is like playing mahjong," he said. In the research process, despite many difficulties and addiction, the more you do it, the more interested you are and the more willing you are to do it. Just like mahjong clubs and cards, every progress in work is also encouragement. "

　　Faith is more like a flower in his heart when it is chilly in spring. He said that insisting on doing something will lead to the sublimation of understanding on the basis of long-term accumulation. In day-to-day scientific research, he sees the charming charm of superconductivity, firmly believes that there will be a breakthrough in superconductivity, and firmly believes that his research has great scientific significance and application value, and can contribute to this country, nation and human civilization.

　　He said that a country’s scientific and technological strength can’t be bought with money, and it can only be based on itself. It is necessary to combine personal interests with the destiny of the country, tackle the problem with teeth, and serve the country with knowledge.

　　CCTV News:On January 18th, the State Council Press Office held a press conference to introduce the operation of agriculture and rural economy in 2022 and answer questions from reporters.

　　Zeng Yande, chief agronomist of the Ministry of Agriculture and Rural Affairs and director of the Development Planning Department, briefly reported the operation of the agricultural and rural economy in 2022.

　　2022 is an extraordinary year. The Ministry of Agriculture and Rural Affairs and the National Rural Revitalization Bureau conscientiously implemented the spirit of the important speech and instructions of the Supreme Leader General Secretary, implemented the decision-making arrangements of the CPC Central Committee and the State Council, effectively responded to the epidemic situation and serious natural disasters in COVID-19, went all out to ensure supply, overcome difficulties and keep the bottom line, made concerted efforts to promote revitalization, and fully completed the annual goals and tasks, providing a solid foundation and strong support for the overall stability of the economy and society.

　　First, grain production has achieved another bumper harvest, and the supply security foundation has remained stable. Grain output reached a record high. The sown area of grain was 1.775 billion mu, an increase of 10.52 million mu over the previous year, and the output was 1,373.1 billion Jin, an increase of 7.4 billion Jin, which remained above 1.3 trillion Jin for eight consecutive years. The effect of soybean oil seed expansion is obvious. The soybean area was 154 million mu, an increase of 27.43 million mu over the previous year, the highest year since 1958. The output was 20.28 million tons, an increase of 3.89 million tons. The rape area reached 109 million mu, an increase of nearly 4 million mu, and the total output of oil crops was 36.53 million tons, an increase of 1.1% over the previous year. Due to the increase in supply and consumption saving, the self-sufficiency rate of edible vegetable oil increased by 1.6 percentage points. The production of live pigs developed steadily. By the end of 2022, the number of fertile sows in China was slightly higher than the green and reasonable regional upper limit of capacity regulation. The annual pork output was 55.41 million tons, an increase of 4.6% over the previous year. At the same time, the production of beef, mutton, milk and aquatic products increased in an all-round way, and the supply of vegetables and fruits was stable.

　　Second, the industrial employment belt has been strengthened, and the results of poverty alleviation have been continuously consolidated. Monitoring assistance is further optimized. Farmers who are at risk of returning to poverty should do their best and help them. More than 65% of the monitored objects have eliminated the risk of returning to poverty, and the rest have also implemented assistance measures. The effect of industry leading agriculture is obvious. The proportion of subsidy funds for rural revitalization promoted by the convergence of central finance for industrial development exceeds 55%, and every poverty-stricken county has cultivated 2-mdash; Three characteristic leading industries, nearly 3/4 of the people out of poverty have established a close interest relationship with new business entities. Going out to work remains stable. In the whole year, the employment scale of poverty-stricken laborers was 32.78 million, exceeding the annual target of 2.59 million.

　　Third, science and technology and equipment are strongly supported, and modern agricultural construction continues to advance. The revitalization of seed industry has been further promoted. The general survey of agricultural germplasm resources was basically completed, and 120,000 agricultural germplasm resources were newly collected, 330,000 livestock and poultry germplasm resources and 78,000 aquatic germplasm resources were collected and produced. Key agricultural core technologies have been tackled in an orderly manner, major agricultural biological breeding projects have been launched and implemented, and the pilot application of genetically modified corn and soybean industrialization has progressed smoothly. The protection of cultivated land has been intensified. The task of building 100 million mu of high-standard farmland in the whole year was overfulfilled, and the cumulative construction target of 1 billion mu was achieved as scheduled. The implementation of conservation tillage covers an area of 83 million mu, and the pilot task of the third national soil survey was generally completed. Breakthrough in the creation of agricultural machinery and equipment. 240 horsepower stepless speed change tractors, rape transplanters and other short-board machines were successfully mass-produced, and the loss rate of grain machinery was controlled within 3%.

　　Fourth, the transformation of production methods was accelerated, and the green transformation of agriculture continued to advance. Collaborative promotion of agricultural non-point source pollution control. The utilization rates of chemical fertilizers and pesticides all exceeded 41%, and the utilization rates of livestock manure, straw and agricultural film exceeded 78%, 88% and 80% respectively. The ecological environment in key river basins has been improved rapidly. The ten-year ban on fishing in the Yangtze River has been vigorously promoted, and the protection of aquatic biological resources has continued to improve. The effect of deep water saving in the Yellow River basin has begun to show, and the agricultural ecological environment problems have been treated. The supply of green and high-quality agricultural products increased. Agricultural production and the "three products and one standard" of agricultural products have been further promoted. The output of green, organic and geographical indications has reached 11%, and the pass rate of routine monitoring of agricultural products quality and safety has reached 97.6%.

　　Fifth, rural industries have been cultivated and expanded, and channels for increasing farmers’ income have been continuously broadened. The processing and circulation of agricultural products has developed steadily. It is estimated that the operating income of agricultural products processing industry above designated size will exceed 18.5 trillion yuan, an increase of about 4%, and support various market entities to build more than 16,000 cold storage and preservation facilities for agricultural products. The development of new industries and formats in rural areas was accelerated. Rural leisure tourism has resumed development, and the online retail sales of agricultural products are expected to increase by about 10%. Rural employment and entrepreneurship have a good momentum, and the local employment rate is over 90%. Upgrading the construction of agricultural parks. 40 new industrial clusters with advantages and characteristics, 50 national modern agricultural industrial parks and 200 strong agricultural towns will be built, and the rural industrial base will be further consolidated. Driven by industry and employment, the annual per capita disposable income of rural residents reached 20,133 yuan, a real increase of 4.2%, and the per capita income ratio of urban and rural residents was 2.45, which was 0.05 lower than that in 2021.

　　Sixth, rural construction has been carried out in an all-round way, and the living conditions of farmers have been continuously improved. Renovation and improvement of rural human settlements. The penetration rate of sanitary toilets in rural areas in China exceeds 73%, more than 90% of domestic garbage in natural villages has been collected and transported, and 95% of villages have carried out cleaning operations. The construction of rural public facilities was promoted in an orderly manner. The construction of industrial roads, resource roads and tourist roads in rural areas was accelerated, water supply and power supply, network communication, farmers’ housing and other facilities were gradually improved, and the level of public services such as rural education, medical care and old-age care was steadily improved. The effectiveness of rural governance has been continuously enhanced. A total of 199 demonstration villages and towns and 1992 demonstration villages have been established nationwide, and governance methods such as point system, list system and digitalization have been comprehensively promoted.

　　Seventh, the expansion of rural reform has deepened, and the kinetic energy of rural development has continued to increase. The key reform tasks have been steadily advanced. After the expiration of the second round of land contract, the pilot project was extended to 21 provinces for another 30 years. Two pilot projects, namely, the reform of homestead system and the special rectification of rural land occupation and housing construction, were carried out in an orderly manner, and the results of the reform of rural collective property rights system were consolidated and improved. The main body of new agricultural management has developed and expanded. Family farms and farmers’ cooperatives reached 3.9 million and 2.22 million respectively. Agricultural socialization service covers an area of 1.87 billion mu and drives more than 89 million small farmers. Trade in agricultural products grew rapidly. The total import and export volume reached $334.32 billion. Among them, imports were US$ 236.06 billion, up by 7.4% over the previous year, and exports were US$ 98.26 billion, up by 16.5% over the previous year.

　　Generally speaking, the agricultural and rural economic development in the past year has withstood multiple tests, achieved more than expected results, stabilized the basic disk and consolidated the ballast stone. This year, the Ministry of Agriculture and Rural Affairs and the National Rural Revitalization Bureau will fully implement the spirit of the 20th National Congress of the Communist Party of China, conscientiously implement the decision-making arrangements of the CPC Central Committee and the State Council, anchor the goal of building an agricultural power, fully adhere to the two bottom lines of ensuring national food security and not returning to poverty on a large scale, solidly promote key tasks such as rural development, rural construction and rural governance, build a livable and beautiful countryside, and make new progress in comprehensively promoting rural revitalization and accelerating agricultural and rural modernization.

CCTV News:Mention "bonus hunter", everyone is familiar with it. Now, the word often refers to participating in various preferential activities to save money or profit from it. Some wool can reap benefits, but some wool not only can’t reap benefits, but even it will break the law.

In June this year, a number of company employees were sentenced in a case caused by "bonus hunter".

The incident occurred in a complaint phone call received by a shopping mall. The customer complained about a private car with a license plate number beginning with Su N. After inquiry, the staff found that the car often went in and out of the parking lot of the mall, and all the parking fees were settled in the mobile phone client of the mall by deducting points. What shocked the staff even more was that more than 100 different mobile phone numbers were bound to the name of this car.Moreover, the parking fee of the car is also abnormal, and no parking fee has been paid for almost a month.　

The staff of the shopping mall expanded the search scope and found that there were about 120 vehicles with similar situations, and a large number of different mobile phone numbers were bound to the names of these license plate information. After preliminary estimation, in 2020 alone, the shopping mall lost nearly 370,000 yuan in parking fees.

Next to this shopping mall is an office building where many companies work. Deng, a company employee, parked his car in the underground parking lot of this shopping mall almost every day in order to pick up and drop off customers.

Deng said that the parking rule of this shopping mall is that a car is free for the first hour, and after one hour, it will be charged according to the hourly rate in 10 yuan, with the daily limit of 80 yuan. When a mobile phone number registers a new member on the mobile phone client of the mall for the first time, it can also get 500 points, which can be exchanged for one-hour parking time in the parking lot of the mall.

One day in June 2020, Deng heard from his colleagues that there was a software called "Gathering Codes and Receiving Codes", which claimed that parking for one hour was only 2 cents.

Deng said that if you want to use this software, you have to recharge it first. After the recharge is successful, you can get a strange mobile phone number by clicking the get new number function in the software and selecting the place to park. Next, use this number to register new users of the parking mall. After that, you can return to the software interface of the mall, fill in the verification code obtained by registration, and you can successfully register as a member. At the same time, you can get 500 points sent by this mall to deduct the parking fee.

Operate it once an hour, eight times a day, and spend 1.6 yuan money, you can park your car until after work. And if you pay the parking fee in full, you need 80 yuan. In this way, this software called "Gathering Codes and Receiving Codes" has become an open secret among employees of Deng’s company.　

The staff of the mall reported the case quickly. According to the vehicle data provided by the mall, the police sorted out and determined the owner information of 120 cars involved. After verification, these car owners are almost all staff members in this office building next to the shopping mall. On January 5, 2021, the police launched an operation. In the end, 25 car owners including Deng were listed as suspects in this case.

Car owners were very surprised. Why were they summoned to the police station because of this? First of all, they think it’s just greed, and why greed touches on illegal crimes.

Subsequently, the police conducted further investigations on the software called "Gathering Code and Receiving Code" used by Deng. According to the relevant registration information, the police locked Shimou, the person in charge of this company, and quickly arrested him.

Shimou confessed that he downloaded the original code of the software from a forum registered overseas and developed this code-receiving software.

In June, 2021, the Yangpu District People’s Court of Shanghai successively heard these cases. In the first instance, the court sentenced Shimou, a software developer, to six months’ imprisonment and fined him for the crime of helping information network criminal activities. In the first instance, the court sentenced three car owners to imprisonment ranging from six months to nine months for fraud, all of which were suspended for one year and fined. The investigation and trial of other people involved in the case are still in progress. Deng and other drivers were granted bail pending trial by Yangpu Branch of Shanghai Public Security Bureau because the amount involved did not meet the criteria of criminal law.

　　Cctv newsRecently, the State Council issued the "Thirteenth Five-Year National Informatization Plan", which is a guiding document for China’s informatization development in the next five years. It requires the construction of an ubiquitous advanced information infrastructure system, constantly promoting the evolution and upgrading of infrastructure, creating an integrated information infrastructure for land, sea, air and space, coordinating the construction of comprehensive infrastructure, and accelerating the network construction in rural and remote areas. Implementing the requirements of planning tasks and building a ubiquitous advanced information infrastructure system are the strong driving force for promoting China’s informatization development as a whole and the inevitable requirement for building a network power.

　　First, the construction of ubiquitous advanced information infrastructure system is a strong driving force to promote the development of informatization in China.

　　At present, China’s various and large-scale information infrastructures such as fiber-optic broadband network, mobile broadband network, radio and television network, industry-specific communication network, cloud computing data center, content distribution network, Internet of Things, terrestrial fiber-optic network, submarine fiber-optic network and satellite communication network are being built and formed. Build a ubiquitous advanced information infrastructure architecture with multi-network integration, multi-dimensional integration and comprehensive intelligence, and form a strong driving force to promote the development of informatization in China.

　　First, the construction of ubiquitous advanced information infrastructure system is the demand direction of informatization development. At present, China is in an important stage of modernization driven by informatization, and the information economy has become the direction of economic and social transformation and development, which urgently needs a new round of information technology leading forces to join. China’s information infrastructure technology development level is in a rapidly rising stage, and fixed broadband network fiber, mobile network broadband, and next generation Internet evolution are the development trends of infrastructure. During the "Thirteenth Five-Year Plan" period, the scale of ultra-wideband optical fiber access network with 10G PON technology was built, 400G wavelength division multiplexing system technology became the mainstream of backbone optical transmission network construction, 4G+ mobile broadband technology was widely used, China led the formation of 5G global unified technical standards, 5G trial and commercial networks began to take shape, and IPv6 technology was fully introduced into the Internet. With the evolution and upgrading of China’s advanced technology in information infrastructure, a converged broadband network infrastructure system with advanced technology, high speed, convenience, safety and reliability covering urban and rural areas has been basically built, making the use of information infrastructure more convenient and becoming an indispensable part of people’s daily work and life.

　　Second, the information infrastructure of multi-network integration promotes the development of informatization to be consistent. Different types of network infrastructure have their own advantages in promoting the development of information technology, but under the condition that the development of information technology tends to be consistent, it is possible to develop multi-network integration. In recent years, China has been promoting the development of triple play, especially in the 13th Five-Year Plan. With the accelerated implementation of broadband strategy, the construction of all-optical network has achieved initial results, and all-optical network counties, all-optical network cities and all-optical network provinces have emerged constantly. At present, China Unicom has completed 8 all-optical network provinces and 130 all-optical network cities nationwide, and China Telecom announced that it will achieve 100% coverage of all-optical networks this year. According to the statistics of the Ministry of Industry and Information Technology, as of October, the total number of FTTH/0 users with optical fiber access reached 215 million, accounting for 73% of the total broadband users, a net increase of 66.74 million over the end of last year. Fiber-optic broadband access network can provide ultra-high-definition 4K video services over 50-100M, and the total number of IPTV users has reached 78.73 million, with a net increase of 32.83 million from January to October. The process of two-way transformation of China’s radio and television network has been accelerated, and FTTH technology has been adopted. By the third quarter, the two-way network covered more than 145 million users and broadband users reached 23.288 million, of which FTTH users reached 5.637 million.China is promoting the construction of the next generation radio and television network, adopting the wired and wireless satellite convergence network construction mode to meet the needs of users for radio and television convergence media services at any time, at any place and at any terminal, and to promote the construction of an interconnected, cross-border interactive, intelligent, secure and credible media cloud.

　　Third, build an information infrastructure that integrates land, sea, air and space to promote the coordinated development of informatization. China’s informatization development field has been fully expanded to land, ocean, sky, space and other production, life and scientific research spaces, which requires the construction of an integrated information infrastructure with land, sea, air and space. On the land side, firstly, the optical fiber network and the mobile network are used as connecting media, so as to speed up the deep coverage of points, lines and areas such as cities, villages and towns, traffic roads, and key crowded areas, build an ultra-high-speed and large-capacity optical transmission technology to upgrade the backbone transmission network, realize the flexible choice of users’ optical fiber broadband and 4G mobile broadband access service capabilities of more than 100 megabytes, and continuously improve the high-speed transmission and access capabilities of information networks. The second is to promote the interconnection of information and communication facilities with neighboring countries, open up the land information Silk Road from Central Asia to West Asia and from South Asia to the Indian Ocean, encourage Internet enterprises and operating enterprises to build overseas business nodes and application infrastructure, and enhance network accessibility and business access. The third is to speed up the deployment of Internet of Things facilities, cloud computing centers, big data platforms, content distribution networks and other facilities, accelerate the evolution of network facilities with information transmission as the core to intelligent information infrastructure integrating perception, transmission, storage, calculation and processing, and realize the network moving with the cloud. In the ocean, we will strengthen the construction of submarine optical cables, expand the transmission channels of submarine optical cables between coastal cities and islands, actively promote the construction of submarine cables in America, Europe and Africa, and build a maritime information silk road that reaches the whole world. Accelerate the research and development and application of marine and underwater communication technologies,Provide broadband satellite communication, mobile communication, ship networking and other solutions, build a private network for offshore mobile clusters, promote the deployment of public broadband wireless networks at sea, enhance marine emergency communication capabilities, and promote the construction of smart oceans. In the sky, the first is to build an information network integrating heaven and earth, coordinate the construction and application of Beidou system, speed up the construction of Beidou navigation and positioning reference station network, coordinate the technical application in related fields of satellite mobile communication and broadband satellite communication system, form the standards and specifications of key technologies of China’s independent satellite communication system and broadband satellite communication system, and cultivate an industrial chain covering satellite manufacturing, launch, satellite ground equipment and satellite application and operation. Second, speed up the application of frontier technologies such as floating platform, low-orbit satellite mobile communication and space Internet, promote the development of information infrastructure in integration of defense and civilian technologies, enhance the information security of space network, and build a global space-based information network. In August this year, China successfully launched the world’s first quantum science experimental satellite, connecting the Beijing node of the quantum secure communication backbone network with it, and building the world’s first practical wide-area quantum communication network integrating heaven and earth.

　　Fourth, build comprehensive infrastructure to promote the in-depth development of information application. Accelerate the construction of public facilities and municipal infrastructure such as power grid, railway, highway and water network, and supporting information infrastructure such as characteristic towns and beautiful countryside. Realize synchronous planning, synchronous design and synchronous construction with other infrastructures, ensure the space, location, power and other resources for the construction and development of information infrastructure, endow infrastructure with networking wisdom function, and build intelligent comprehensive infrastructure. Accelerate the supporting construction of information infrastructure for transmission and distribution networks, improve the ability of intelligent automation control, promote the construction of national smart grid and build a global energy Internet. Accelerate the construction of supporting information infrastructure along the transportation line, promote the opening of facilities, innovate the cooperation mode, implement joint construction and sharing, and build an intelligent transportation network. Guangdong Province will speed up the construction of town information infrastructure and promote the "internet plus" plan. In the next three years, 10 industrial "internet plus" towns and 50 applied "internet plus" towns will be created. In 2015, Zhejiang Province proposed to cultivate 100 characteristic towns with complete infrastructure in the next three years.

　　Second, China has become a network power, but it is not strong enough to support informatization as the leading force driving modernization.

　　After more than 30 years of telecommunications reform, China’s information infrastructure construction has developed rapidly, and the world’s largest fixed broadband network and mobile broadband network have been built, becoming a veritable network power. First, in terms of user scale, as of the end of October 2016, the total number of Internet broadband access users of the three basic telecommunications companies reached 294 million, of which the total number of FTTH/0 users with optical fiber access reached 215 million, accounting for 73%, ranking third after Japan and South Korea; The total number of mobile phone users reached 1.321 billion, of which the number of 4G users reached 714 million, surpassing the sum of the United States and Europe and surpassing one third of the world. Second, in terms of network capacity, by the first quarter of 2016, the construction of fiber-optic broadband networks will be accelerated, urban households will basically achieve full coverage of 100 Mbit/s optical fibers, and fixed broadband networks will extend to all townships and 95% administrative villages in the country; The 4G network covers cities and major towns all over the country. Some key cities have deployed 4G+ technology on a large scale, and the pace of commercialization in carrier aggregation and VoLTE has been accelerated in an all-round way. The backbone network architecture has been further optimized, and the network grooming ability and user experience have been greatly improved. Third, in terms of actual network speed, as of the third quarter of 2016, the average download rate of fixed broadband reached 11.03 Mbit/s, and the average download rate of 4G network reached 11.83 Mbit/s, forming a situation in which fixed and mobile broadband rates developed side by side.

　　However, there is still a certain gap with the goal of supporting informatization as the leading force to drive modernization, and the development of information infrastructure still faces many challenges. Mainly manifested in: First, the global ranking of penetration rate is not high. According to the data of broadband access in countries around the world released by the Broadband Commission of the United Nations, in 2015, China’s broadband development was in the top third of the world, lagging behind the four countries of the United States, Britain, Japan and South Korea. Among them, the fixed broadband penetration rate is 18.56%, ranking 57 th in the world; The mobile broadband penetration rate is 56.0%, ranking 69th in the world. The penetration rate of Internet households is 54.17%, and the proportion of netizens is 50.30%, ranking 35th and 46th respectively in developing countries. Second, the actual speed measurement value of broadband in China by foreign institutions is not high. According to Akamai’s report on the Internet in the second quarter of 2016, the global average network speed was 6.1Mbps, up 14% year-on-year. Among them, South Korea’s average network speed is 27Mbps, which continues to rank first in the world. China’s average network speed is 5.2Mbps, a year-on-year increase of 52%, and the global ranking has risen from 100 in the previous quarter to 86th. The report of the speed measuring agency shows that China’s average network speed ranks low in the international rankings, which reflects that China’s international Internet exports are not high, and the per capita international export bandwidth ranks low in the world. Third, the ubiquitous advanced information infrastructure system has not yet been established, the development of multi-network integration is still being promoted, and the information infrastructure pattern of land, sea and air integration has not yet been formed.The consciousness of building comprehensive infrastructure as a whole is not strong enough. Third, rural information infrastructure is still a weak link in development, the proportion of optical fiber to administrative villages is low, the coverage of 4G networks in rural areas is not good, and the digital divide still exists.

　　Third, speed up the network construction in rural and remote areas and improve the universal service level of telecommunications.

　　After more than ten years of national "village-to-village project", the leap-forward development of rural information and communication infrastructure in China has been realized, and a good situation of "telephone service in every village and broadband service in every township" has been achieved. Due to the characteristics of high cost, complex maintenance and poor income of network construction in rural and remote areas, network development has been lagging behind urban areas, which can not well support the development of rural agricultural informatization. By the end of 2015, there are still about 50,000 administrative villages without broadband access, and about 150,000 administrative villages with broadband access need to upgrade their broadband technology. Speeding up the network construction in rural and remote areas and constantly improving the universal service level of telecommunications are of great strategic significance to promoting the overall development level of informatization in China and building a network power.

　　First, recognize the gap between urban and rural information infrastructure development. As of the second quarter of 2016, the average penetration rate of fixed broadband households in China was 56.5%, of which the penetration rate of fixed broadband households in urban areas reached 79%, while that in rural areas was only 29%, with a difference of 50 percentage points between urban and rural areas. As of May 2016, the coverage rate of administrative villages with 4G network was only 65%. As of December 2015, the number of rural netizens in China reached 195 million, and the number of urban netizens was 493 million. Rural netizens accounted for only 28.4% of the total netizens, while the urban population accounted for 56.10%.

　　Second, see clearly the situation faced by rural network construction and development. Under the situation of implementing the strategy of strengthening the country by network, only by comprehensively improving the network capacity in rural and remote areas can we achieve the real strategic goal. China is in a critical period of the simultaneous development of new industrialization, informatization, urbanization and agricultural modernization. Taking informatization as the commanding height of agricultural modernization, only by building perfect information infrastructure in rural and remote areas can we effectively support the development of rural agricultural informatization. During the "Thirteenth Five-Year Plan" period, it is necessary to vigorously implement the network poverty alleviation action to ensure accurate and effective poverty alleviation.

　　Third, promote network construction in rural and remote areas by classification. The administrative villages with no broadband access or broadband access capacity less than 12 Mbit/s will be covered with optical fiber, and 98% of the administrative villages will be connected with optical fiber. More than 50% of rural household users will have access bandwidth above 50Mbps, and access services above 100Mbps will be provided in better areas of the network. Implement 4G network deep coverage for administrative villages with concentrated population. For remote areas, forest and pastoral areas, islands and poverty-stricken areas, flexible networking such as low-frequency mobile cellular, satellite communication and multiple optical fiber combination access technologies will be adopted to promote broadband network coverage of more than 90% of poverty-stricken villages.

　　Fourth, combine rural network construction with rural agricultural informatization. According to the development idea of combining network construction with business application, we will promote rural agricultural informatization as a whole and apply it to the whole process of agricultural production, agricultural product management, agricultural management and rural service. Popularize the informatization construction of rural grass-roots government affairs, promote the construction of broadband campuses and online classrooms in rural primary and secondary schools, promote the application of medical informatization and telemedicine in rural clinics, promote the development of rural e-commerce, and promote the adaptive development of informatization application level and rural network capacity.

　　Fifth, improve the universal service level of telecommunications. We will carry out in-depth pilot work on universal telecommunications service, strengthen the guidance of central financial funds, drive local governments to strengthen overall planning and policy support, promote enterprises to assume the responsibility of market players, and jointly promote the development of network construction in rural and remote areas. Adhere to market-oriented operation, encourage private capital and radio and television enterprises to participate in competition fairly, and fully mobilize the enthusiasm of all kinds of enterprises to participate in universal telecommunications services. We will implement the national guidance on speeding up and reducing fees, encourage operators to formulate tariff packages that are in line with rural consumption levels and habits, give preferential communication tariffs to disadvantaged groups, and let 600 million farmers share the fruits of information network development to ensure that residents in rural and remote areas can use, afford and make good use of information services.

Blue whale financial reporter work platform

Li Xian shouted to the photographer: Please stop.

Karry Studio issued a document to boycott stalking fan.

Yang Mi was shot maliciously on behalf of others.

YiBo thundered against stalking fan.

From May 11th to today, four celebrity artists boarded the hot search one after another in four days. Under the influence of stalking fan’s malicious acting, the private lives of celebrities were frequently harassed.

What is a substitute? Who is driving the growth of the agency industry? What kind of gray industrial chain is hidden behind the star generation? Today, we will talk about the agency industry in the entertainment industry.

Behind the professional shooting:

Xiao Zhan has 50 pictures of 2000 yuan, and Esther Yu has 300 600 yuan.

Before understanding the industrial chain, let’s popularize the slang of rice circles.

Instead of taking pictures, the abbreviation DP is often used in rice circles. Acting as a substitute is a popular career in rice circles in recent two years. Many stars have their own fan groups and stations, but sometimes these fans may not be able to go to the activities attended by the stars. At this time, they will find people who can go to the activities and pay them to help shoot their favorite stars. These photos and videos will be used to maintain the operation of the stations, for fans to lick the screen and bring more traffic exposure to idols.

Stalking fan: An extreme and crazy person among the fans of artists and stars. In order to satisfy their own selfish desires, they like to follow, peep, and secretly photograph the daily and undisclosed trips (airports, hotels, etc.) and work of stars, harass their favorite stars, and affect the private lives of artists (and their families). Illegitimate behavior will cause great trouble to the idol himself, and at the same time, it will disturb public order, bring hidden dangers to public safety, and often deal a blow to the idol’s reputation.

We can often see such videos on social media such as Weibo and Tik Tok. When stars appear in public places such as airports, they are often chased and photographed by a large number of people. There are many fans among the people who take pictures, but more likely they are "professional photographers".

As a matter of fact, there has been a long history of the phenomenon of substitute filming. In recent days, Yang Mi, Li Xian, Karry and others have taken the initiative to denounce this chaos, which shows that the substitute filming industry is rampant. Since last year, many stars have been harassed by substitute filming and boarded the hot search.

For example, Jason Wu was angry when he was forced to take photos, Angelababy fans were beaten when they were forced to take photos, and Sean Xiao fans were crazy about taking photos and disturbing the order of the airport.

Many people may be curious, how do professional substitute photographers get the travel information of stars and shoot them? What’s the use of taking these photos? Who will buy it? How does the agency industry work from top to bottom?

The reporter’s investigation found that there are many sellers selling celebrity privacy itineraries on the Internet, and the privacy of a large number of celebrities such as Jackson Yee, Karry, Arqie, YiBo, Adam and Esther Yu is sold in the circle of friends, including flight information, ID number, passport number, mobile phone number, micro-signal, website account and even playlist of listening to music APP.

In order to avoid security risks, reporters were told that sensitive words should be expressed by abbreviations during the communication with such sellers.

For example:

Brush off-SG household registration map-HJ flight-HB/

High-speed rail-gt/address-DZ ID card-SFZ

This kind of sellers are the upstream practitioners in the industrial chain of professional proxy photography. They provide the basic guarantee for proxy photography by providing the privacy itinerary of stars.

After obtaining the itinerary, the work of taking pictures on behalf of them began. In addition to professional shooting equipment, they also need to have excellent technical acumen. Take the airport as an example. Professional agents will specially buy air tickets to go through the security check with artists, and then refund them after filming, so as to minimize the work cost.

If you get a first-hand photo, you will resell it to fans or a third-party seller, and then the seller will sell it to fans at a higher price to earn the difference.

The reporter interviewed a number of sellers and provided the reporter with the price of the corresponding star.

Take Esther Yu, a popular trainee in "Youth has You 2", for example, 100 pictures start as a small bag, and the price is 260 yuan; 160 pictures are big bags, and the price is 330 yuan; The whole package starts with 300 pictures, and the price is 600 yuan.

In addition, the quality of photos, the clarity and the popularity of artists will all determine the selling price. For example, only 30 pictures in Jackson Yee are sold in 260 yuan, and the price of substitute photos in Sean Xiao is much higher than that of ordinary stars, and 50 pictures can be sold for 2,000 yuan.

To put it simply, acting as a proxy means that groups mainly in stalking fan take photos by tracking stars, and then resell them to fans to earn money.

Invade privacy and disturb public order

The chaos in the auction industry is frequent.

Where there is demand, there is a market. Driven by interests, the agency group is growing. Searching for "selling pictures dp" on Weibo, we can find that everything related to substitute photography can be done in it, from information selling to photo trading. It can be seen that as a product of the development of fan economy to a certain stage, Daipai has now formed a complete industrial chain from top to bottom.

Nowadays, the development of the agency industry has gradually lost control. According to previous CCTV news reports, there were 20 recorded fan alarms in 2017 only in Terminal T3 of the Capital Airport. From January to July 2018, there were 7 recorded fan alarms. In the process of filming, it not only causes inconvenience to artists, but also seriously affects the operation order of the airport, brings inconvenience to airport staff, and even brings congestion to the airport, causing certain security risks.

In addition to disturbing public order, there are many kinds of chaos in the agency auction industry, such as invasion of privacy, which leads artists to file complaints one after another.

As early as 2019, the People’s Daily published an article criticizing the agency auction. The People’s Daily said that Hugh and Jason Wu angrily denounced the agency auction, and Sean Xiao was blocked by the agency auction, resulting in flight delays … In recent years, the agency auction business has repeatedly been out of order and ignored social rules, which seriously disturbed social order. No interest should override the public interest. Only by correcting the traffic direction with rules and leading the fan economy with order can the traffic economy return to rationality and go further.

In 2024, the 18th Beijing Auto Show opened. This is not the Beijing Auto Show. Some overseas auto makers have come. Half of the booths of BYD and Xiaomi are foreigners, and the arrival of Lei Jun and Zhou Hongyi can be said to be a walking traffic leader, but Tesla is still not seen.

As far as FAW Hongqi is concerned, it has not only introduced a number of concept models, such as the concept car of Hongqi Golden Sunflower, the design concept of integrating the car body light group, wheels and other places into the golden sunflower, the gull wing door blessing, not to mention how fashionable it is, but also the convertible version of Hongqi EH7, which is definitely a bold attempt.

In addition, the brand-new Hongqi Guoya was officially unveiled at the Beijing Auto Show. The new car has been declared before and is expected to be officially listed soon.

And we see that the new car and the declaration map are also different, and the overall body is relatively round, creating an elegant and atmospheric image of the country.

Specifically, in fact, many elements of sunflower have been added to the car body, such as the position of vents on both sides and the brand-new taillight shape. The headlight group is more retro, and the classic straight waterfall grille of the family is preserved. Together with the hub with dense spokes, the lifting beacon and the two-color body, it is simply a "domestic Rolls Royce".

Of course, after all, the new car is 5353mm long and the wheelbase is 3260 mm. Under the slender body lines, the power is also quite exaggerated. According to the application information, the new car will be available in 3.0T oil-electric hybrid and 4.0T oil-electric hybrid versions.

Finally: In any case, Hongqi Automobile has luxury genes, which will improve the design and power configuration, and it is also the representative of luxury cars in big countries in overseas markets.

Gaishi automobile news?On March 3rd, Volvo Cars announced that its global sales in February was 51,286 vehicles, up 22% year-on-year, setting a record high in the same period. In February, the Recharge series (pure electric vehicles and plug-in hybrid vehicles) led the global sales growth of Volvo Cars, accounting for 40% of the global sales of Volvo Cars. Among them, the sales of pure electric vehicles of Volvo Cars increased by 187% year-on-year, accounting for 19%.

From the market point of view, in February, Volvo cars performed strongly in the US market, with sales increasing by 38% compared with last February, reaching 8,560 vehicles, of which Recharge models accounted for 29%. The sales growth of Volvo Cars in the US market is mainly driven by SUV series models, but it is also partly due to the decline of the company’s production and sales due to supply chain restrictions in February last year.

The sales volume of Volvo cars in China reached 13,066 vehicles, up 50% year-on-year, of which Recharge models accounted for 9%. Part of the reason for the strong growth of the company’s sales in China is that the timing of the Spring Festival affected the sales in February 2022. The company’s sales in Europe reached 21,278 vehicles, up 9% year-on-year, of which Recharge models accounted for 64%.

In terms of best-selling models, in February, XC60 II was the best-selling model of Volvo Cars in the world, with sales reaching 16,103 (compared with 13,503 in the same period of 2022), followed by XC40 and XC90 II with sales of 15,435 and 7,120 respectively (compared with 12,611 and 5,582 in the same period of 2022).

Volvo Cars previously said that 2023 will be a crucial year for the company to further accelerate its transformation. Although there will still be challenges such as global turmoil, uncertainty and rising prices in 2023, Volvo Cars’ retail sales in 2023 are expected to achieve double-digit steady growth through efforts to reduce costs and increase efficiency on a global scale, without any unexpected circumstances such as supply chain interruption.
