  Core reading

  A large number of young people who both have ideals and advocate hard work go to the front line of poverty alleviation and show their talents at the grassroots level. They use new ideas and technologies that young people are good at to solve some long-standing problems; With active creation, the story of youth helping the poor is interpreted. Those busy youth figures have become a beautiful scenery of the times.

 

  In 2015, Hu Yao, a young teacher of Guizhou University, went to the front line of poverty alleviation to accurately solve the employment and training problems of poor rural households through data collection, activation and application.

  In the same year, Liu Yifeng, who was still a sophomore in the Department of Thermal Energy in Tsinghua University, decided to drop out of school and start a business. He devoted himself to the mass production of high-efficiency crystalline silicon solar materials, devoted himself to photovoltaic poverty alleviation and brought real benefits to the people.

  In October 2019, Hu Yao and Liu Yifeng met on the podium, and they also got the certificate of "China Youth Entrepreneurship Award and Special Award for Poverty Alleviation".

  Getting rid of poverty is a great cause and has a strong appeal to contemporary youth. A large number of young people who both have ideals and advocate hard work go to the front line of poverty alleviation and show their talents at the grassroots level. They use new ideas and technologies that young people are good at to solve some long-standing problems; With active creation, the story of youth helping the poor is interpreted. Those busy youth figures have become a beautiful scenery of the times.

  Mobile phones have become a new agricultural tool, and the local "mountain products" has become a "tip" in online celebrity.

  "Our fruits are all delivered now, and they are guaranteed to be fresh. Please rest assured!"

  Click on the short video of "Nine Sisters of Clever Women". After 80, Gan Youqin showed the citrus that was about to be packaged and delivered to the camera, and peeled off one at random, with thin and juicy skin and firm meat. Behind Gan Youqin, more than a dozen workers are working on the assembly line of e-commerce warehouse, such as moving fruit, picking fruit, sub-packaging, weighing and packaging. Click on the comment again, and the netizen left a message: "The fruit is sweet and delicious, and I like it for you!"

  Ling shan, Qinzhou City, Guangxi Province is a famous "hometown of fruits", and Gan Youqin’s home is in Suwutang Village, Sanhai Town, ling shan. Because she ranks Laojiu at home, Gan Youqin named her short video account "Qiaofu Jiumei". Cooking, working in the fields, fishing with nets, climbing trees and picking fruits … … Gan Youqin often shares rural life in short videos, so he has accumulated a large number of followers and has an unusual "carrying power".

  In September 2017, Gan Youqin’s "carrying power" broke out. "Add WeChat to sell for a few days and sell more than 1,000 kilograms every day. When the number of WeChat people was full, I opened an online store. " At the end of October 2018, Gan Youqin’s online store pre-sold seasonal fruits and oranges, which coincided with the launch of the "Buy while Watching" activity on the video platform. The short video directly linked to the store, which brought huge traffic to the online store. "One week after the pre-sale was launched, the order increased to more than 90,000 kilograms, and I tasted ‘ Short video+e-commerce ’ The sweetness! " Gan Youqin now has over 10 million fans and over 100 million video hits, making him a "country online celebrity" with a hoe and a live broadcast.

  Mobile phones have become a new agricultural tool, and the local "mountain products" has also become a "sharp commodity" in online celebrity. Gan Youqin began to ponder to help the villagers get rid of poverty together. "In the past, villagers stayed up late to sell fruits, picked them during the day, and waited for wholesalers to collect them at night. From 1 am to 6 am, it took more than two months to sell them out. Now through short video promotion, you can help everyone sell out the fruit in one week. " Gan Youqin and his wife built an e-commerce base covering an area of 10 mu, providing jobs for more than 50 poor local households. "We pick fruits in the morning and send them to all parts of the country in the afternoon, and the fruits in the village have a market!" Driven by her, many young people who went out to work began to return home to contract orchards.

  Last year, the team of "Qiaofu Jiumei" promoted and sold more than 4 million kilograms of agricultural and sideline products, with an output value of more than 23 million yuan. Among them, litchi alone sold more than 350 thousand kilograms, and also set a record of daily sales of 17.5 thousand kilograms; Mango in Wuli Town, ling shan has a slow sales of 75,000 kilograms, all of which are sold out by Gan Youqin; Xing an tangerine in Guilin is unsalable. With her help, it directly sold 65,000 kilograms and indirectly helped sell more than 300,000 kilograms.

  Nowadays, Lingshan industrial base is blooming everywhere, and the villagers grow oranges, plant fruit seedlings and open online stores, leading a colorful life. At present, there are more than 400 e-commerce enterprises in ling shan, employing more than 2,000 people, with accumulated sales exceeding 630 million yuan.

  Taking the "short video+e-commerce" express train, Gan Youqin and the villagers in Dashan found the stage of self-realization and opened up a new mode of agricultural product circulation. "I am still a real farmer, and I hope to drive more young people back to their hometowns to do a good job in agricultural products, so that everyone can embark on the road of getting rich together." Gan Youqin said.

  Use big data to find the needs of villagers and match employment training services.

  What is the data?

  For Hu Yao, CEO of Guizhou Renhe Zhiyuan Data Service Co., Ltd., the data are not simple ones and zeros, but the actual needs of rural poverty-stricken areas can be tapped through data, thus providing more accurate assistance to poor villagers.

  Before starting a business, Hu Yao was a doctoral student at Guizhou University, majoring in big data mining and application, and stayed on as a teacher after graduation. In 2012, Hu Yao’s research team cooperated with enterprises to develop a "mobile photo studio" system, and with the support of the government, provided one-stop social security card business card printing service in rural areas of Guizhou. "Villagers can run social security cards at their doorsteps without going to the county." He and his team entered the village to provide data services for villagers, covering 61 counties (cities) in Guizhou Province and covering more than 20,000 natural villages, with a cumulative service of over 10 million people.

  In this process, Hu Yao found that there are a lot of unmet needs of villagers: asymmetric employment information, unable to effectively match jobs after training … … In April 2015, Hu Yao founded Guizhou Renhe Zhiyuan Data Service Co., Ltd., "with one mind to help villagers get rid of poverty."

  With the data, how to use it? "Most poor households have a low level of education, lack of skills, and asymmetric information between employers and labor forces, which makes it difficult for rural surplus labor to digest." Hu Yao cut in from this, cooperated with the local employment department, and used data to get through the "last mile" of poverty alleviation: to build an intelligent employment platform, form a personal portrait based on scene-based service data, then form a job portrait based on job requirements, and finally realize intelligent job matching through AI technology. After three years of operation, more than 120,000 jobs have been recommended.

  Some poor households have high employment expectations, but lack relevant work ability. What should I do? Hu Yaohe’s team also developed an intelligent management system for trainers, and cooperated with local governments and training schools to provide targeted job training for poor households through data matching. Yan Minqin, from Weining Yi, Hui and Miao Autonomous County, Guizhou Province, thought that, like the villagers in Dashan, it was her destiny in this life to work in the fields and take care of the children. Her husband used to work odd jobs to make ends meet, and the couple lived in poverty. However, through the matching of big data information, Yan Minqin and his wife participated in nursing training and successfully became nursing workers in the affiliated hospital of Guizhou Medical University, and their lives became better and better. "They let me see the changes of professional and technical training to poor villagers, and also strengthened the confidence of the officers in starting a business." Hu Yao said.

  Regarding the future, Hu Yao wants to continue to do a good job in rural employment services. "Use data to continuously serve rural people, make data generate value and transmit more temperature."

  Empowering traditional industries with new technologies to help farmers increase their income

  Using idle resources, can poor households get rid of poverty by sitting at home? Liu Yifeng, 24, did it.

  In 2015, Liu Yifeng, a sophomore in the Department of Thermal Energy in Tsinghua University, decided to drop out of school and start a business, and established Beijing Badu Sunshine Technology Co., Ltd., mainly engaged in the research and development of flexible crystalline silicon solar materials. At the critical period of poverty alleviation, Liu Yifeng decided to help precision poverty alleviation through clean energy technology. "Using the company’s own solar panels, the photovoltaic power station will be built on the roofs of ordinary people’s homes, and the income from electricity sales will be distributed to residents, bringing stable income to poor households."

  Enterprises are responsible for the construction of power stations, and ordinary people only need to take simple daily care of solar panels, wipe the dust and keep them clean. Taking Chengde, Hebei Province as an example, Liu Yifeng calculated an account: "The enterprise invested 12,000 yuan, and the government subsidized 12,000 yuan to build a 3.24 kW photovoltaic poverty alleviation power station. Every household can generate 5,000 kWh of electricity every year in normal operation, and ordinary people can earn 2,000 yuan, directly entering the bank card or passbook." Today, photovoltaic poverty alleviation business has covered Hanzhong, Shaanxi, Chengde, Hebei, Liuzhou, Guangxi and other places, helping thousands of people to successfully get rid of poverty.

  "We have an operation and maintenance center in the local area. The power station is equipped with a data collector, a sensor and a communication module. The data is transmitted to the online system every 5 seconds, and an alarm is given in time if there is any abnormality. The operation and maintenance personnel will judge the fault category before carrying out maintenance." Liu Yifeng said that photovoltaic poverty alleviation is much more affordable and takes a long time, which naturally wins the trust of the masses.

  Chengde, Hebei Province also attracted Zhang Jing who returned home to start a business. After returning from studying in Britain and giving up her white-collar job in Beijing, Zhang Jing established Chengde ruitai Food Co., Ltd. in Xinglong County, Chengde, her hometown.

  Xinglong County is known as "the hometown of Chinese hawthorn", and the income from hawthorn production and processing accounts for 1/3 of the per capita net income of local farmers. Zhang Jing knows the weight of this sweet and sour fruit in the hearts of villagers. "To help people get rid of poverty, the transformation and upgrading of hawthorn industry is the key. It must be supported by core technology and enhance the added value of hawthorn through innovative technology. "

  Zhang Jing also established Hebei (Chengde) Hawthorn Industrial Technology Research Institute and served as the president, and hired many well-known fruit experts to build a first-class multi-disciplinary and collaborative innovation Hawthorn R&D team at home and abroad. The construction of science and technology platform makes hawthorn from peel, pulp to stone full of treasures: hawthorn peel is rich in flavanol; The pulp is a well-deserved "king of pulp", which can extract dietary fiber; Fruit pulp can be used to brew "hawthorn red wine"; Even the seeds of hawthorn can be made into rose red liquid antibacterial liquid. Up to now, they have participated in 20 scientific research projects, 4 achievements have been transformed, 4 new products have been developed and 5 patents have been held.

  With the breakthrough of key technologies, hawthorn industry is undergoing a qualitative change, which has laid a solid foundation for fruit farmers to increase their income and poor households to get rid of poverty. "In 2018, the price of the scale in Xinglong Mountain was one kilogram in 0.7 yuan, which eventually rose to one kilogram in 1.3 yuan under the drive of our company, driving nearly 4,000 farmers to increase their income." Zhang Jing said that by absorbing more than 1,400 poor households’ shares, promoting employment, establishing poverty alleviation factories and purchasing at protective prices, the enterprise has solved the employment of hundreds of people, and has returned more than 2.4 million yuan of poor households’ shares and paid more than 1.4 million yuan in dividends.

  Show youthful grace in tackling poverty

  A native "online celebrity with goods", a university teacher who provides employment services with big data, and a returnee youth who uses technology to enhance the added value of agricultural products & HELIP; … When young people walk into the ancient land with ideals and creativity, young generate shines brilliantly. These promising things make young people think. How should young people win the future? Pluralistic societies have diverse answers, but they have one thing in common, that is, they use their keen eyes to discover the needs of the country and society, and then use what they have learned and the empowerment of the times to meet these needs, so that they can truly enter the big era and win their own future.

  The battlefield of poverty alleviation and rural revitalization is precisely where the current social demand is strong, and it is also a stage for young people to make great achievements. Looking around, many of the more than 2.8 million resident cadres and the first secretary are young people on the main battlefield of poverty alleviation. They are using their youth to interpret wonderful poverty alleviation stories; A large number of young people who go out to work also choose to return home to start businesses and rediscover the charm and advantages of their hometown … … The trickle is merging into a big river and surging into a torrent of the times.

  A generation has the mission of a generation. Getting rid of poverty is an examination question of the times given by history. How can the problem solvers be short of young people who can best reflect the spirit of the times? We expect more young people to write wonderful chapters in life in the process of poverty alleviation and rural revitalization.

Graphene material can make a mobile phone charge an electric car in three minutes.

  Not long ago, Tsinghua University’s research team released an invention of "Smart Graphene artificial larynx", which makes use of the advantages of porous graphene materials to create an integrated acoustic device that is transceivable and wearable, and is expected to solve the "speaking" problem of deaf people in the future.

  Internationally, researchers from institutions such as Cambridge University reported that they found a new way to "awaken" the superconductivity of graphene, and the awakened graphene can be used to manufacture supercomputers.

  Graphene is the hottest new material at present. In the aviation field, people use "rare elements" to describe materials that are as light as air and as hard as steel. Previously, titanium alloy was considered as the ideal choice closest to this quality, while "rising star" graphene was considered as a step closer to the "rare element" of human dreams.

  What is graphene?

  At present, the thinnest, lightest and strongest material in the world is 100 times harder than the strongest steel.

  Like diamond, graphite is a form of carbon. The difference is that, due to the different atomic structures, diamond is the hardest thing on earth, while graphite is one of the softest minerals, which are often made into graphite rods and pencil lead. Graphene is stripped from graphite material and only consists of a layer of carbon atoms on the plane.

  It can be said that one of the characteristics of graphene is its thinnest material in the world, which is only one atom thick, about 0.3 nanometer, which is one-hundredth of the thickness of A4 paper and one-fifth of the thickness of hair. At the same time, it can conduct electricity, and the movement speed of electrons in graphene reaches 1000 km/s, which is 1/300 of the speed of light. Thin, strong, conductive and thermal … … These characteristics of graphene give people a lot of imagination.

  Dr. Kong Yuechan, deputy director of the Key Laboratory of Microwave and Millimeter Wave Monolithic Integration and Modular Circuits of China Electric Power Department, said that the hardness of graphene is very strong, 100 times stronger than the strongest steel now; Graphene’s electron running speed is also very high, 10 times that of silicon, which is very suitable for developing the next generation of UHF electronic devices. In addition, graphene is also a master of heat conduction, which is 10 times stronger than the most thermally conductive metal silver.

  The characteristics of graphene are also very "fun". For example, when a drop of water rolls on the surface of graphene, graphene can keenly "perceive" subtle movements and generate continuous current. This characteristic provides scientists with a new idea to obtain electric energy from the flow of water.

  "Graphene can sense a single electron, and the movement of charged particles on the surface of graphene can cause the electrons in graphene to move rapidly, realizing the sensing and power generation process." Lin Shisheng, an associate professor at the School of Information and Electronic Engineering of Zhejiang University, said that this feature of graphene can be used in many applications in energy and electronic sensing, such as using an umbrella coated with graphene to generate electricity in rainy days, or making it into a sensitive sensing device.

  It is these comprehensive properties that make graphene attract unprecedented attention, and some people even begin to predict that the appearance of graphene will lead an industrial revolution triggered by material progress.

  How to obtain graphene

  For the first time in the world, a single layer of graphene was obtained by "sticking" it with transparent glue.

  The first time people got graphene, they used a "simple and rude" method.

  Graphene itself exists in nature. Graphene is a thin layer of carbon atoms, and a hexagonal ring is formed between the atoms, and the rings are connected to form a honeycomb plane. It is graphite when stacked layer by layer, and graphite with a thickness of 1 mm contains about 3 million layers of graphene. Pencil lightly across the paper, leaving traces that may be several to dozens of layers of graphene. Previously, this two-dimensional structure of carbon has always existed in people’s conjecture, but it is difficult to peel off the single-layer structure. The key problem is how to stratify graphite into extremely thin slices.

  Many people also had this experience when they were students. When they wrote typos on paper, they would use transparent tape to stick the typos off. But no one thought that it was such a simple method that people discovered the mysterious graphene.

  To make graphene, simply speaking, it is necessary to thin graphite, not by cutting, not by grinding, but by sticking. In 2004, Heim and Novoselov of the University of Manchester in the United Kingdom repeatedly stuck and tore a graphite sheet with transparent adhesive, and the thickness of the graphite sheet gradually decreased, eventually forming graphene with a thickness of only 0.335 nm, that is, graphene with an atomic thickness. This is the first time in the world to get a single layer of graphene, so two scientists won the 2010 Nobel Prize in Physics.

  Dr. Wu Yun, a senior engineer in the Key Laboratory of Microwave and Millimeter Wave Monolithic Integration and Modular Circuits of 55 China Electric Power Institute, gave a demonstration to the reporter. He stuck a small piece of graphite on the tape and then tore it overlapping. After sticking for half an hour, the tape was covered with gray graphite, and then the graphite was transferred to a clean silicon wafer with tape.

  Wu Yun said, what we saw at this time was not graphene, because graphene is not only very thin, but also has a light transmittance of over 97%, which is almost completely transparent, and people can’t see it at all. To find it, we have to use special technical means. But this is already a multi-layer graphite sheet, and then the number of layers can be located and determined by technical means, and finally the single-layer graphene can be found.

  Experts say that this is just the initial method of producing graphene. The mechanical stripping method, which evolved from the adhesive tape paper sticking method, is just a method for preparing graphene in the laboratory. At present, with the technological progress, high-quality graphene can be produced more.

  What will graphene bring?

  Using graphene material, the screen of mobile phone can be easily bent or even folded.

  The appearance of graphene is expected to bring surprises to our lives. Mobile phone charging can be "second charging", mobile phone screen can be easily bent or even folded, and cars can use graphene static conductive tires to avoid deflagration caused by friction electrification … … From aerospace and electronic information to energy conservation and environmental protection, great changes are likely to take place in many fields by using the characteristics of graphene.

  Using graphene instead of silicon can improve the performance of electronic chips. Researchers are currently introducing the production and application of graphene into the semiconductor industry, and the technological revolution triggered by graphene is likely to start with our common small chips.

  The basic material of electronic chips is silicon. However, with the increasing density of components on the chip, the distance between the two components on the top chip is less than 10 nanometers, almost reaching the limit of silicon materials. What should I do if I want to continue to improve my performance? Researchers began to try to partially replace the role of silicon with graphene.

  "Devices made of graphene can theoretically reach ten times or even hundreds of times the frequency of silicon, which can be applied to radar and greatly improve the resolution of radar. Moreover, it is widely used in communication and imaging. " Kong Yuechan said, moreover, the current R&D and production equipment of graphene is the same as that of ordinary semiconductor equipment, and the existing technology development can be based on mature equipment and processes, laying the foundation for subsequent engineering development.

  Researchers are still doing another big thing. They attached graphene to a gold foil with a thickness of only 50 nanometers, and then used a new method to completely transfer graphene to a soft plastic sheet.

  Kong Yuechan said that graphene can be transferred to any substrate that researchers want through flexible methods, such as a special plastic substrate for electronic devices, which is flexible and suitable for the preparation process of transistors. Through the special graphene transfer technology, the gold foil with graphene is attached to the plastic sheet, and based on this, electronic devices with certain functions are prepared on this plastic sheet. Most importantly, such electronic devices can be easily bent. In the future, whether it is a foldable display screen or a wearable device that can be implanted into the human body, it may be realized by such graphene devices.

  Another highly anticipated application field of graphene is the storage of electric energy. In Tianjin Electric Power Research Institute, researchers here are conducting research on the most advanced capacitors. Capacitors, like batteries, can be used to store electric energy. Its advantage lies in its fast charging speed, which can be fully charged in a few minutes and can be reused for tens of thousands of times. But it doesn’t store as much electricity as a battery, and it can’t be used in life by storing enough electricity.

  "This is the slurry made of modified graphene. Next, we will apply these slurries to aluminum foil through a coater and become the positive electrode for our graphene capacitor." Dr. Ding Fei, executive deputy director of 18 National Defense Science and Technology Key Laboratories of Chemical and Physical Power Technology in China Electric Power Department, said that capacitor materials have a vital impact on the performance of capacitors. Through the further modification of graphene materials, researchers are making the storage capacity of capacitors closer to the battery step by step, and at the same time, its ultra-fast charging speed can bring more convenience to people’s lives. "The modified graphene capacitor we are making can be fully charged in a few minutes, and its energy density is expected to be close to that of existing lithium batteries after a period of time."

  Energy density refers to the amount of energy stored in a substance with a certain space or mass. The higher the energy density, the stronger the power storage capacity of this substance. According to Ding Fei, the energy density of the modified graphene capacitor they have developed has reached more than three times that of the traditional capacitor. Although it is still in the laboratory research stage, the powerful capabilities of graphene materials have enabled the R&D team to see the broad prospects for the application of modified graphene capacitors.

  In the future, when the charging facilities are becoming more and more perfect, it may take two or three minutes for electric vehicles to fully charge with graphene batteries.

  Gao Tao, director of No.55 Institute of China Electric Power Department and director of the Key Laboratory of Microwave and Millimeter Wave Monolithic Integration and Modular Circuits, believes that even under laboratory conditions, the magical properties of graphene have not been fully released. At the same time, there are still many challenges at the technical level, and there is still a long way to go for real large-scale application. However, by strengthening the combination of demand and research, important breakthroughs have been made in the preparation of graphene materials and device development. Graphene, a new generation of strategic emerging materials, will greatly change people’s lives.

What is female "negative blowing"? Is this normal? Don’t lose heart, there are four other treatments.

Qian Qian (a pseudonym), 33, is a white-collar worker in the Internet industry, and her career is on the rise, so she went to work soon after giving birth and had no time to take care of her health.

Recently, Qian Qian and her husband have also been unhappy.

The thing is, Qian Qian and her husband always heard the sound of "poof, poof, poof" when they were doing things a few days ago, which made them particularly embarrassed. In the end, they lacked interest and made a hasty decision. They slept with their backs to each other and didn’t talk again that night.

From that day on, they didn’t take the initiative to mention it, but Qian Qian’s heart was very concerned, and she came to the postpartum rehabilitation department of the hospital for help. The doctor on duty gave her a pelvic floor examination and told her:"This is the phenomenon of’ negative blowing’ caused by pelvic floor dysfunction.

Blowing in the shade means that due to the change of pressure, there is an airflow rushing out of the private parts of women, accompanied by a sound similar to fart. If women have "vaginal blowing" after childbirth, it may be accompanied byPelvic floor dysfunctionThe problem.

When women are pregnant and giving birth, the gravity on the pelvic floor increases.Hormone level changeandInjury caused by childbirthUnder the combined action of many factors, the muscle strength of pelvic floor muscles decreases, which affects the function of pelvic organs and causes a series of typical symptoms, includingUrinary incontinence, fecal incontinence, sexual dysfunctionWait, this is "pelvic floor dysfunction".

Relevant data show that women who have no symptoms of urinary incontinence after the first delivery,There is still a 19% chance of urinary incontinence five years after delivery.; And women who have urinary incontinence within three months after the first delivery,The probability of urinary incontinence five years after delivery is as high as 92.%。

Pelvic floor dysfunction not only causes urinary incontinence, but if women can’t recover pelvic function in time after delivery, their body function will continue to decline with age.The probability of chronic pelvic pain, organ prolapse, uterine prolapse, anterior and posterior vaginal wall bulging, sexual dysfunction and other problems will also increase.Especially after menopause, the level of estrogen drops, which is more prominent.

Epidemiological investigation shows that middle-aged and elderly women in some areas of China,The prevalence of pelvic floor dysfunction is as high as 30% ~ 50%, and the older you are, the higher the incidence is.. If you suspect that you have pelvic floor dysfunction, you can first make a simple self-test through the following 10 descriptions:

1, hip, coccyx and waist had a history of falls;

2. There is a feeling of falling in the pelvic cavity, or the pelvic organs fall off and slide out;

3, urinating more than twice a night;

4. Pain in pelvic area, including hip, coccyx, lower waist, pubic symphysis, bladder area, etc.

5. During the menstrual period, there is discomfort or involvement in the lower abdomen;

6. Discomforts in the urinary system, such as urgency, frequent urination, urinary incontinence, slow urine flow, endless urine, and urination;

7. Discomforts in defecation or rectum, such as irregular defecation, long-term constipation, nervous or painful defecation, endless defecation, feeling bowel prolapse during defecation, and long defecation time;

8, sedentary will increase discomfort;

9. Feel pain and discomfort in sexual life, or aggravate other discomfort symptoms;

10. You need to hold up the swollen part of the vagina with your fingers in order to urinate smoothly.

In the above description,If three or more items are met.Then there is likely to be pelvic floor dysfunction, so it is recommended to go to the hospital as soon as possible.Professional evaluation of pelvic floor dysfunctionThe examination includes: special test, external genital examination (observation of perineum and sensory test, functional test, internal diagnosis, pelvic floor muscle pressure evaluation, etc.

When it comes to pelvic floor muscle exercise, many people know Kegel exercise, but the American Journal of Obstetrics and Gynecology points out that more than half of people do Kegel exercise incorrectly, and 25% of them make mistakes in exertion, which adds extra pressure to muscles and aggravates symptoms.

The correct steps of Kegel’s movement should be like this:

① Attention should be paid to emptying the bladder before the activity, and beginners can lie flat on the bed to finish it.

② Tighten the pelvic muscles and keep them for five minutes.

③ Then relax the pelvic muscles for 10 seconds.

Repeat the tightening and relaxing movements for 10 times as a group, and do 3~5 groups every day to achieve the training purpose.

of course,Those with good physical fitness can also make an advanced version.Lie flat with your legs apart, your knees bent and your feet flat on the ground. When searching for pelvic floor muscles, lift your hips and hold on for 10 seconds, then slowly lower your hips and relax the pelvic floor muscles, and do it ten times.

During Kegel exercise, you don’t need to hold your breath during the whole process, just breathe normally. In addition, the pelvic floor muscles will be "used in and discarded", so even if the pelvic floor muscles recover, it is recommended to continue regular exercise.

If Kegel exercise doesn’t work for you, don’t lose heart. There are still mature treatments in clinic, such as:

1, bioelectrical stimulation

Low-frequency electrical stimulation of vagina and abdominal wall can promote passive contraction of pelvic floor muscles, and each treatment lasts about 30 minutes, which is painless and non-invasive, and can make personalized treatment plan according to the patient’s situation.

2. CO2 lattice laser

Stimulate the growth of fibroblasts and new blood vessels on the inner wall of vagina, promote the proliferation of collagen, make the inner wall thicker and more elastic, which is suitable for patients with mild symptoms, milder than surgery and shorter in time, and each treatment lasts for 5~6 minutes.

3, high intensity focused electromagnetic

Similar to bioelectricity stimulation, it uses human neurobioelectricity to stimulate pelvic floor muscles to contract, with more accurate focusing effect, stronger penetration and wider and deeper stimulation range.

4. Surgical correction

In-depth integration and development of cultural tourism in various places

Tengwang Pavilion in Nanchang, Jiangxi Province, reciting the Preface of Tengwang Pavilion for free tickets; Datang, a city that never sleeps in Xi ‘an, Shaanxi Province, won a souvenir with "Li Bai" on poetry; Enjoy the "Oriental Sculpture Exhibition Hall" at Maijishan Grottoes in Tianshui, Gansu … This year, the cultural tourism market continues to heat up, and many places "add points" for cultural tourism consumption.

In recent years, the trend of cultural inheritance and development driving the cultural tourism market has become more and more obvious. Cultural heritage sites, archaeological sites, historical and cultural cities (towns), national cultural parks and other cultural tourism destinations create new consumption scenes and attract more and more tourists. According to statistics, in 2022, more than 70% of tourists participated in more than two cultural activities on holidays. Under the background of deep integration and development of cultural tourism, cultural tourism projects carrying excellent Chinese traditional culture have attracted much attention.

Innovative development of cultural attractions is full of vitality.

At the beginning of the Hua Deng, it was located around Sansu Temple in Dongpo District, Meishan, Sichuan. There were many tourists coming and going, and the streets became more and more lively. "Night tour of historical and cultural blocks, exquisite architectural decoration lighting layout, people feel a different kind of historical charm." A tourist lamented.

It is the key to attract and retain tourists to have excellent cultural tourism projects. Dongpo District has vigorously developed the night economy, created a cultural tourist area of "Dongpo Drunk with the Moon", launched five characteristic tourist routes, and developed more than 10 research courses. In 2022, the number of A-level scenic spots in the whole region was 1.0282 million, and the total tourism revenue was 4.782 billion yuan.

Not only Dongpo District and Sansu Temple, in recent years, more and more places have modernized and innovatively presented cultural attractions, avoiding "one-size-fits-all visits to historical sites" and enhancing tourism attraction.

In Qufu, Shandong Province, Nishan Shengjing Scenic Area launched a large-scale live performance "Golden Sound and Jade Zhen" integrating sound and photoelectricity, which brought the audience an immersive appreciation of the charm of Chinese excellent traditional culture; In Wuhan, Hubei Province, a series of activities invited tourists to punch in the historical scenic area of Hankou and get to know the ancient and modern Jiangcheng again …

Innovative development has opened up a new path for the integration of cultural tourism.

Walking in Nanping, Fujian, where Zhu Xi Garden is located, you can often meet "cartoon Zhuzi" in the streets. From urban landscape, cultural tourism products to animation works, the vivid image of Zhu Xi and Zhu Zi culture have quietly entered people’s daily lives. Lei Xiying, head of the creative team of Cartoon Zhuzi, said: "We will continue to explore Zhuzi culture to make this cultural image more three-dimensional and vivid."

Tang Xiaoyun, vice president of China Tourism Research Institute, said that all localities should cultivate cultural heritage, promote the transformation of cultural and tourism resources into cultural and tourism products, and form a large tourism industry with multi-support, multi-industry symbiosis and multi-integration, so as to stimulate consumption potential with rich supply of cultural and tourism products and diverse cultural and tourism integration formats.

Film and television works have great potential to drive consumption.

Going to a place because of a drama, a movie or a program is a new phenomenon in the current tourism market.

The city streets full of fireworks, unique human history and fascinating scenic spots have made the audience yearn for it; With the help of the spread of film and television works to enhance their popularity, they can attract more tourists who come here.

90% of the location of the hit drama "Go to a Windy Place" was shot in Dali, Yunnan Province, and the location of the location was widely known. According to reports, during the Spring Festival holiday of the Year of the Rabbit, Dali received a total of 4,239,300 tourists, an increase of 219% year-on-year.

Another drama series, Long Moon Blooms, has benefited Bengbu, Anhui Province, whose cultural background is related to it. This year’s "May 1" holiday, Bengbu Cultural Tourism Bureau designed a tour route around the play and opened four free bus lines, allowing fans to punch in the same scenic spot in one step. The data shows that during the May 1 holiday, Bengbu received a total of 4.176 million tourists, up 162.39% from 2019.

"The prosperity of the Commercial Street is amazing, just like the Tang Dynasty in the movie!" Rolling, a senior high school student from Guangzhou, Guangdong, quickly booked a ticket and went to Xi ‘an after watching the movie "Three Wan Li in Chang ‘an", and visited the city that never sleeps on the night of his arrival.

Under the general trend of "film and television+cultural tourism", the popularity of cultural attractions has further started through the presentation of film and television dramas. According to reports, in July this year, Xi’ an City Wall ushered in the peak of passenger flow, an increase of 110% compared with the same period in 2019; The official summer study route launched by the producers of "Three Wan Li in Chang ‘an" is very popular.

On-line and on-line same frequency resonance, new format

Through social platforms to promote local scenery, online and offline new formats of cultural tourism with the same frequency resonance emerge one after another.

Tang Xiaoyun said that the proportion of catering consumption in tourism consumption has remained above 20% for a long time, and 90% of tourists will taste local specialties after arriving at their destinations. Among them, the driving effect of network anchors and bloggers has gradually emerged.

A food blogger on the video website, Li Li, shoots short videos of traditional food, which often attracts netizens to follow the local punch card for early adopters. In the first food video shot in Shandan County, Zhangye City, Gansu Province, diners and chefs sit around and taste the local specialties. Once the video was broadcast, the local passenger flow rose rapidly, and many foreign tourists lined up at the door of the store.

The "national tide" has become a new fashion of consumption, driving the consumption related to intangible cultural heritage to grow steadily. According to the data of Meituan and public comments, in the first three quarters of this year, the search volume with "non-legacy" as the key word increased by 168% year-on-year, and the group purchase orders related to the theme of "non-legacy" increased by 245% year-on-year.

On the public comment APP, a shop called "No.93 Hospital Intangible Heritage Workshop" was very popular, which attracted many netizens to trace it to the front door of Beijing. According to reports, there are nearly 30 group buying projects in the store, and customers can personally make intangible cultural relics with old Beijing characteristics.

According to the interviewees, culture and tourism have entered a new stage of deep integration: on the one hand, there are many types of products, and traditional culture and tourism integration products such as scenic spots, national culture festivals, cultural relics trails and archaeological research are well recognized by the market; On the other hand, there are many ways of integration, such as movies, performing arts, music, cultural creation, digital cultural tourism and festivals. Experts suggest that relevant departments, industry organizations, platform organizations and practitioners should give full play to their respective advantages and leverage their strength to activate new kinetic energy of consumption with traditional culture and realize two-way empowerment of cultural inheritance and development and cultural tourism consumption upgrading.

Football feast is shared by the world

  A piece of 18k gold with a weight of 4.97kg was made into a unique "Hercules Cup" by Italian sculptor Gazzani. Every four years, men’s football teams all over the world fight for the highest honor, and fans all over the world are crazy about watching the ownership of this gold cup.

  Among the more than 200 members of FIFA, dozens are frequent visitors to the Men’s Football World Cup, and more are spectators who can’t get the "tickets". But this does not prevent hundreds of millions of fans all over the world from following Wan Li, or waiting all night to release their enthusiasm for football.

  The fans in China are also passionate about the World Cup. Although China’s men’s soccer team reached the World Cup finals only once, China fans’ "World Cup complex" is not inferior to other regions. In this hot summer, the World Cup will become a hot topic for domestic fans.

  New horizon

  Like many fans’ memories of the World Cup, Laotian, a 63-year-old retired worker, began to watch football in 1982. That year, CCTV broadcasted the World Cup for the first time. "I just bought a black-and-white TV set at home, and I got up in the middle of the night to watch the ball. It was an eye-opener. It turned out that football can play like this!" Laotian recalled.

  Since then, Mr. Tian has never missed a World Cup, and the four-year "staying up late to watch the live broadcast" has almost become a model. In 2002, he also went to South Korea to witness the performance of China’s men’s soccer team in the World Cup. However, since the World Cup in South Africa in 2010, Mr. Laotian has found that the channel for watching the game is no longer just TV, and his son’s generation has already watched the ball on some online platforms. The popularity of the mobile Internet has opened a "new horizon" for fans.

  On the occasion of the countdown to the 2018 World Cup, two video platforms, Mi Gu and Youku, announced that they had reached a cooperation with CCTV, and "pressed the whistle" to win the new media copyright of this World Cup. This means that domestic fans can watch all 64 live HD games on the mobile phone client and PC side of these two companies. "Enjoy the World Cup anytime, anywhere" is no longer just a slogan.

  The time difference between Russia and China is five hours, and many games are in prime time for domestic users. It is roughly estimated that the domestic audience of this World Cup is expected to exceed 1 billion. Relying on the social network platform, the topic of the World Cup will spread explosively. Laotian said that his son has helped him download the mobile APP (application software) for watching the game, and a group of old golfers have also built a WeChat group. "Watching and chatting, the more interesting this World Cup is!"

  new technology

  Jerry Lee, a Tianjin fan, is a loyal fan of the English team, and the quarter-final of the 2010 World Cup still rankles him. "Lampard’s shot crossed the goal line as a whole in slow motion, but it was judged invalid by the referee on duty. A wrong judgment is likely to cost a team four years of hard work." However, despite the introduction of goal-line technology, wall spray and other means, there are still many controversial penalties in the World Cup referee in Brazil, and the referee repeatedly steals the camera to some extent, which reduces the excitement of the game.

  In this World Cup in Russia, the technology of video assistant referee (VAR) will make its debut. This technology has been applied in World Club Cup, Confederations Cup, Super League, Bundesliga, Serie A and other competitions. "We have conducted experiments in more than 1,000 games and found that without VAR, there will be one misjudgment every three games on average, while with VAR, there will be one misjudgment every 19 games. Although it won’t solve all the problems, it’s obviously helpful for the game. " FIFA President infantino said a few days ago.

  It is reported that FIFA will set up 33 broadcast seats in each match of this World Cup, including 8 slow cameras, 6 ultra-slow cameras and 2 seats for observing offside, and screen and confirm key penalties such as goals, penalties and red cards, which will also help the referee to punish some missed violent fouls. The introduction of VAR will make Diego Maradona’s "God’s hand" and Suarez’s "bite innocent" and other loophole-taking behaviors hard to escape.

  However, while reducing "unjust, false and wrong cases", VAR has also been controversial. Frequently stopping the game, affecting the fluency of the game, and making the stoppage time longer are endless. Lampard said frankly that VAR technology is still immature, and it is too early to introduce the World Cup. Of course, more fans may vote for it like FIFA-after all, sometimes disputes and disputes waste no less time than watching videos.

  Is the application of new technology adding color or chaos? Maybe we can only wait for the game to answer. "From the fans’ point of view, if the penalty is more convincing, it will increase the transparency of the game and football will return to its own excitement." Jerry Lee said.

  New sensation

  With Iran’s final submission of the 23-man roster, all 736 players from 32 teams in this Men’s Football World Cup have been confirmed. Among them, there are 9 players from the Super League. These familiar faces who play for Beijing Guoan, Guangzhou Evergrande and other teams make China fans feel more about watching the "home players" game.

  Compared with previous World Cups, this time Russia is not far away. With the development of sports tourism, this World Cup may usher in the largest "sightseeing group" of South Korean fans since the 2002 World Cup in China and China. It is estimated that 100,000 South Korean fans will rush to the scene to watch the game. As of June 8th, the World Cup tickets announced by FIFA show that China fans have bought more than 40,000 tickets, exceeding expectations.

  In addition, China elements have been deeply blended with the World Cup. One third of the 15 sponsors and partners listed by official website in the Russian World Cup are China enterprises. From the peripheral products such as mascots and fans’ equipment, to the air-conditioning equipment in venues and billboards beside the stadium, China elements are readily available.

  The World Cup is a festival for fans all over the world. People participate in it, not only to watch the game. As far as predicting the results of the game is concerned, Pele, the king of the ball, is famous all over the world. Paul Octopus created the magic of predicting all the results of eight games in the 2010 World Cup. It is said that the official of the World Cup in Russia also owns a white Persian cat named Achilles, and I don’t know how to behave.

  The suspense of winning or losing the men’s soccer World Cup match and the elegant demeanor of the star players all affect the hearts of China fans. Perhaps it is to support a certain team and feel the "heartbeat acceleration" from the ups and downs of the green story; Perhaps it is a kind of nostalgia, the days that those classic moments accompanied, and also recorded their lost youth; Maybe it’s just a fad to follow the trend and seek common interests in hot topics … In any case, the curtain of the 2018 Men’s Football World Cup will open. In the next month or so, football will ignite the passion of fans, and a football feast will bring new memories to fans.
