Recently, "Fire Dragon Duel" released the latest stills and figures, and the explosion scene in the stills was thrilling. In the play, Dawn once again performed in a sloppy image, and her face was ferocious. The pain of losing her wife filled her heart with hatred, and some clues were found from a murder case. Richie Jen, on the other hand, is gentle in appearance, efficient in handling cases and has a strong desire in his heart. He broke out at any time and his subordinates died unexpectedly, bringing out his secret. Liao Qizhi lives for his daughter, an old policeman, and hides important clues. No one knows whether he is evil or not. Mainland Wang Baoqiang came to Hong Kong to make a living, and his pregnant wife was caught and used by gangsters. At this moment, he can’t help holding a gun. Michelle Ye, as a policewoman, is a subordinate of Dawn and has a secret crush on Dawn. Bidai Syulan, as Richie Jen’s girlfriend, has a special status, which is also the most important reason why Qi made the final decision. Yue Xiaojun plays the robber. Although he is a robber, he is full of joy. Tan Kai also plays the role of a robber, but heartless and ruthless.

　　"Fire Dragon Fight" tells the story of a bizarre prostitute’s murder case, which has aroused doubts. The murder weapon is a chain saw specially used by the US military. Wen Fang (Dawn), the inspector of the major crimes unit, suspects that another arms case is brewing. Sir Ji (Richie Jen) of the narcotics squad intervened to join the investigation. The Chinese side was eager to solve the case and tried to find out the real murderer and break its plan before more serious incidents occurred. However, Identification Bureau got clues from the deceased, but pointed to a confidant in the Chinese army. The source cooperated with Ji sir at nothing, and the personal problems of the two agents gradually emerged. The source began to suspect that someone was corrupt and colluded with gangs to do evil. However, since his wife died, he has been depressed, his emotions are getting out of control, and he is in a mystery. However, the enemy and I are inseparable, and he has fallen into close encounter of mahjong, and the crisis is approaching.

　　Director Lin Chaoxian’s previous work Witness won the Best Actor and Best Supporting Actor in the Hong Kong Film Awards, while Fire Dragon attracted Dawn and Richie Jen, the former rarely makes gun battles now, and the latter is now Du Qifeng’s favorite. The new work Accident was selected as the main competition unit of this Venice Film Festival. In "Fire Dragon Fight", they will all subvert their past roles. According to Richie Jen, they hope to surprise the audience with contrast.

　　Lin Chaoxian’s representative works include The Beast Criminal Police, River’s Lake Emergency, Heavy Police, Witness and so on, which won him the Golden Award for Best Director. His works can often explore human nature and examine good and evil beyond highly skilled gun battles. "Fire Dragon Duel" is a film with a suspenseful layout and an unpredictable human nature. "Fire Dragon" is a kind of folk custom with Hong Kong characteristics: more than 100 years ago, there was a plague in a big pit in Hong Kong. Later, people tied up the pearl grass, filled it with incense, and danced like a fire dragon. Since then, the plague has been miraculously eliminated. Lin Chaoxian said that this film focuses on the plague in people’s hearts.

　　CCTV News:According to "Traffic Management Bureau of the Ministry of Public Security" WeChat WeChat official account news, in order to effectively enhance the traffic safety awareness of express logistics drivers and promote the safety management level of express logistics transportation, the Traffic Management Bureau of the Ministry of Public Security announced four typical road traffic accidents involving express logistics vehicles this year.

　　◆ On January 31st, a SF Express heavy van collided with a minibus parked in front of the same lane on the Hunwu Expressway, killing one person and injuring two others. After investigation, the cause of the accident was that the driver of the heavy van neglected to observe and handled it improperly.

　　◆ On February 13th, a heavy-duty semi-trailer tractor of Yunda Express entered the opposite lane after colliding with the central isolation guardrail on the G93 Chengdu-Chongqing Ring Expressway, and collided with a minibus driving in the opposite direction, resulting in 6 deaths and 1 injury. After investigation, the cause of the accident was the driver’s fatigue driving, speeding, improper handling and the technical condition of the vehicle not meeting the safety standards.

　　◆ On September 19th, a light van of postal express collided with an electric tricycle passing along a crosswalk at an intersection in Fuyang City, Anhui Province, killing three people. After investigation, the cause of the accident was that when the light van passed the intersection, the driver neglected to observe and slowed down when it met the crosswalk.

　　◆ On October 30th, a light truck rear-ended and collided with a heavy-duty semi-trailer tractor transported by cold chain in front of Xu-Guang Expressway, killing five people. After preliminary investigation, the heavy-duty semi-trailer tractor in the accident was suspected of illegal modification and ultra-low speed driving.

　　Tips from the Traffic Management Bureau of the Ministry of Public Security — —

　　Express logistics enterpriseIt is necessary to earnestly fulfill the main responsibility of traffic safety, eliminate potential safety risks at the source in a timely manner, scientifically and reasonably arrange the time limit for transportation and distribution, strengthen dynamic supervision of their vehicles, and remind and urge drivers to strictly abide by the law and drive safely.

　　Driver of express logistics industryCheck the vehicle in advance before driving to eliminate potential safety hazards in time; Scientifically plan the itinerary and route, ensure the rest time and prevent fatigue driving; Strictly abide by traffic safety laws and regulations when driving, and don’t overspeed, overload, drive too fast, or drive in the prescribed lane; Control the speed and drive carefully and safely when passing through the curved slope section, the water-facing cliff section and the night time; When crossing the intersection, you should strictly observe the traffic signals, pay attention to observing, slowing down and avoiding pedestrians, especially when turning right, you should be alert to the blind area of vision and ensure safety before passing.

In recent years, the development of new energy vehicles is fierce, and it is not difficult to find that they are developing in the direction of high intelligence. He Xiaopeng, the founder of Xpeng Motors, even said: I believe that in 2025, the word "assist" in automatic assisted driving will be removed, and the era of real automatic driving will be entered. Are we really going to usher in the era of fully automatic driving? To answer this question, we might as well take two brands, Tesla Model 3 and Tucki P5, as examples.

Tesla: FSD

Tesla’s intelligent assisted driving ability is leading in the industry, and its pure visual route is also the object that many car companies follow.

In North America, FSD will release the version of FSD Beta V11 in August. It can also be seen from the evaluation of Big V that the effect is quite good. The new version is more mature and sophisticated, and it can flexibly avoid at intersections without signal lights, and can also continuously change lanes and overtake. Unfortunately, there is no plan to introduce FSD into China at present. Why? Quite simply, the road conditions in China are far more complicated than those in North America, and there are many people and cars. Therefore, Tesla FSD, which works in North America, which is sparsely populated, may not work in China.

Moreover, although the cost of pure vision scheme is low, it is a camera after all, and it is impossible to switch the focal length and depth of field at any time like the human eye, so it is difficult to ensure that the details in the field of vision are clear. Even the human eye will misjudge the driving route and distance in complex road conditions, light or environment. Therefore, the pure vision scheme relying on the camera has environmental limitations.

Xpeng Motors: city NGP

Xpeng Motors has been focusing on technology research and development in recent years, and has achieved good results.

For example, high-speed NGP, cross-floor memory parking, and just after OTA upgrade, the updated enhanced ACC-L/LCC-L (only applicable to Xiaopeng P5), which can assist driving in difficult urban road conditions such as unmarked road sections and large curvature curves, etc.

Different from Tesla, Xpeng Motors adopts the multi-sensor fusion route. Besides 12 ultrasonic sensors, 5 millimeter-wave radars, 13 high-sensor cameras and a group of high-precision positioning units, there are also two laser radars, which greatly improves the sensing accuracy and distance of Tucki P5 and avoids environmental interference as much as possible. Therefore, compared with the pure visual route, multi-sensor fusion will be more stable and accurate.

It is reported that the city NGP function of Tucki P5 will be launched soon, which is also the first city navigation assisted driving function in China. So, what about the city NGP? What is the solution in the face of complex domestic road conditions? These can be seen from the city NGP test video released by Xpeng Motors not long ago.

In the video, Tucki P5 traveled a total of 26 kilometers in the urban area of Guangzhou, crossing the three central urban areas of Guangzhou. During this period, it showed a very high level of coping with complicated situations such as traffic lights, left-right turns, tunnels, bends, U-turns, roundabout, bridges, switching between main and auxiliary roads, confluence, misaligned lane openings, and road conditions in the construction area.

Whether He Xiaopeng’s predicted entry into the era of full-scale autonomous driving in 2025 can really be realized is unknown. However, judging from the current level and development trend of intelligent assisted driving in Xpeng Motors, I believe that Tucki will bring us more surprises, and we can still expect a wave.

1905 movie network news A youth suspense film directed by Jin Zhencheng and starring Chen Douling and Haoran Liu will be released soon. Today, the film official released the propaganda song MV of the same name, which was the first time for Ayanga to give a voice to the film, and once again brought surprises and expectations to the audience.

When the sound comes to the scene, Ayanga outlines the picture of youth with singing.

The film "Twins" tells the story that Li Pin (Haoran Liu), a student of an art school, received a mysterious entrustment one day, and the entrusted content was only a portrait of a girl named Tao (Chen Douling). In order to complete this entrustment, Li Pin went to a mansion in the forest alone. In the mansion, Li Pin met Tao, a beautiful girl in a wheelchair. The pure temperament and beautiful face of Tao made Li Pin feel very good, but with the deepening of the story, Li Pin gradually discovered that behind Tao’s clear eyes, there were still unknown secrets.

In order to match the plot, the film side specially added the image of "painting" in the creation of the propaganda song. With Ayanga’s delicate singing, MV unfolds like a picture scroll. The beginning of the song is gentle and comfortable, which fully shows the happiness and beauty when the two young people first met and got along. Ayanga’s ethereal singing, Chen Douling’s green face and Haoran Liu’s warm smile complement each other, which fully reflects the youthful atmosphere of the film. With the deepening of the plot, Haoran Liu gradually discovered many doubts in the house, and Chen Douling also had strange reactions one after another. All this caused a crisis of trust between the two, and the melody of the song was accelerated at this time. In the dispute between the two, the whole song reached the emotional high point. Ayanga used a loud treble to render the atmosphere of conflict, which made the sound and painting of the whole MV perfectly integrated, giving people a sense of being there.

Strive for Excellence, triple charm explodes the audience’s expectation

For "Twin", from shooting to release, it can be said that it is full of twists and turns. The film was filmed three years ago, but in order to improve the quality of the film, the film maker spent a lot of time making up and editing, and it took the film maker three years to complete the production under the daily pressure of countless audiences. In the words of Lv Jianmin, the producer of the film, it is "the child is finally mature and can come out to meet everyone". Adhering to the attitude of Excellence, it takes a lot of manpower and material resources to polish, and the film is only to live up to the expectations of the audience.

In addition to the full sincerity of the production team, "Twins" also witnessed the "first time" of Chen Douling and Ayanga: Chen Douling broke through himself for the first time, and one person played two roles; Ayanga gave a voice to the film for the first time, and gave a wonderful singing that won people’s hearts. This also gives Twin a meaning beyond the film itself. With the triple charms of Chen Douling, Haoran Liu and Ayanga, the expectations of the audience have also soared at a cubic speed. The number of people who want to watch on the Cat’s Eye platform has exceeded 150,000, and that of Taobao Film has exceeded 210,000. The propaganda song of the same name "Twin Boys" topped the weekly list of QQ music popularity list, reaching the peak gold single certification, and the audience felt that "I have to wait for you at last" and "I have to go to the cinema to support" are the best proof.

　 　 　 The film "Twins" will soon land in major theaters across the country on May 18th. At present, the film has been pre-sold, and the audience interested in the film can arrange it!

　　General situation and typical practices of gigabit city construction

　　I. General situation

　　By the end of October 2022, a total of 110 cities in China had reached the standard of mega-city construction and completed the summary and evaluation work, accounting for about one-third of all prefecture-level cities. Among them, 29 gigacities will be built in 2021 and 81 gigacities will be built in 2022. In terms of regional distribution, 41 gigacities have been built in the eastern region, 29 gigacities in the central region and 40 gigacities in the western region.

　　Second, the key indicators

　　(A) "Double Gigabit" network construction

　　By the end of October, 2022, the average coverage rate of urban family gigabit optical network in China’s gigabit cities exceeded 100%, achieving full coverage of urban family gigabit optical network. The average number of 5G base stations per 10,000 people in gigabit cities is 22.2, which is higher than the national average (15.7/10,000 people). Among them, the first batch of gigabit cities has an average of 25.8/10,000 people, and the second batch has an average of 19.1/10,000 people. The average proportion of 10G-PON ports in gigabit cities reached 46.7%, which was higher than the national average (32.1%), among which the first batch of gigabit cities reached 52.9% on average and the second batch reached 40.8% on average.

　　(B) "Double Gigabit" user development

Among them, the first batch of gigabit cities reached an average of 38.3%, and the second batch of gigabit cities reached an average of 39.5%.

　　(III) Coverage of 5G networks in key places

　　Gigabit cities are municipal public hospitals (above Grade III), key universities, key areas of cultural tourism, and key places such as railway stations (above Grade II), trunk airports and key roads that offer passenger transport services. The access rate of 5G networks is over 80%, and the signal level of 5G networks and other indicators meet the relevant construction standards, among which the access rate of 5G in 84 key places in cities reaches 100%.

　　(D) "Double Gigabit" application innovation

　　Gigabit cities have vigorously promoted the integrated application of new technologies such as 5G and Gigabit optical networks in the fields of information consumption, vertical industries, people’s livelihood, digital government, etc., and actively explored the construction scheme and business model of "double Gigabit" network collaborative deployment, bringing digital changes in management and production methods for the development of local characteristic industries and traditional enterprises. Many projects won the national awards of "Blooming Cup" 5G application solicitation competition and "Guanghua Cup" Gigabit optical network application innovation competition. Jiangsu Nantong University Affiliated Hospital has built a "double Gigabit" intelligent operating room, realizing the application of Gigabit optical network+operating room environmental equipment, Gigabit optical network +VR remote surgery teaching, Gigabit optical network+remote diagnosis live broadcast, and reducing the cost of a single operating room from 3 million yuan to 1.5 million yuan, saving construction cost by 50%. Guangdong Foshan Chuangxing Precision Manufacturing Co., Ltd. built a production intranet based on the "Double Gigabit" network, which can simultaneously adapt to multiple application scenarios such as intelligent scheduling, intelligent warehouse management and accurate workpiece positioning. The product yield increased by 16%, the material preparation cost decreased by 12 times, and the labor cost decreased by 38.6%. The application of "Double Gigabit" smart mine in Panzhihua Pangang Group Mining Company of Sichuan Province has realized the application of remote control of open-pit mining equipment and real-time monitoring of high-definition video of operation scenes, and the annual income of application can reach one-third of the construction cost.

　　Iii. Policy support

　　Gigabit cities focus on the difficulties and pain points in the construction and application of "double Gigabit" networks in the region, continue to increase policy support, cultivate market demand, guide various market players to exert their joint efforts and actively participate in the construction of Gigabit cities, and a number of typical practices with demonstration effects have emerged.

　　(A) Optimize the "Double Gigabit" network construction environment

　　Some gigabit cities have formulated special plans for communication infrastructure, which have been incorporated into the land and space planning at the same level. Ya ‘an, Sichuan, Luoyang, Henan, Taizhou, Jiangsu, etc. listed the Communication Development Management Office as a member of the Municipal Land and Resources Planning Committee, participated in the municipal land and resources planning, and implemented special plans such as optical fiber network construction planning and 5G station site planning in the overall urban planning and regulatory detailed planning.

　　Some Gigabit cities have strengthened the open sharing of public resources, facilitating the construction of "double Gigabit" networks. Wenzhou, Zhejiang, Dezhou, Shandong, Hohhot, Inner Mongolia, etc., establish a public resource open contact system, and open up social resources such as lampposts, monitoring poles and road signs owned by government agencies, institutions and state-owned enterprises free of charge; Nanyang, Henan Province, coordinates and solves difficult station sites, and promotes the unconditional and free opening of public places such as highways, airports, railway stations, high-speed railway station, large venues and scenic spots to the construction of 5G base stations; Guiyang, Guizhou strictly regulates the types of fees, and promotes the management units in residential quarters, commercial buildings and other places to provide access convenience for the construction of communication facilities. It is forbidden to collect unreasonable fees such as entrance fees, coordination fees and apportionment fees under various pretexts.

　　In some mega-cities, when examining and approving municipal projects such as parks, roads and buildings, optical fiber pipelines (poles) and base station sites are included in the design review and completion acceptance of building schemes. Ganzhou, Jiangxi, Yichang, Hubei, Yinchuan, Ningxia, etc. will incorporate the construction of communication facilities into the joint drawing review and joint acceptance of new construction, municipal administration, transportation and other projects; In the renovation project of old residential areas and buildings in xiong’an new area, Hebei Province, the construction of optical fiber network was included in the project construction approval management system.

　　(B) reduce the "double Gigabit" network construction costs.

　　Some gigabit cities provide electricity security for communication facilities such as 5G, reduce electricity costs, and strictly regulate the types of charges. In Weihai, Shandong Province, Fuzhou, Jiangxi Province, and other deployment areas, the power supply entities of 5G base stations will carry out self-examination and self-correction, and organize market supervision departments to investigate and deal with illegal electricity price increases, electricity charges and other price violations by the power supply entities; Qinzhou, Guangxi, implements fine management of electricity cost, and reduces the network electricity fee of each carrier frequency through the strategy of "one pressure, two changes and three reductions" (one pressure means to reduce the electricity price, the second change means to transform and change the C-RAN into a straight one, and the third reduction means to reduce capacity and combine cabinets, save energy and reduce emissions, and intelligently shut down and save energy).

　　Some gigabit cities provide financial subsidies in the construction, operation and maintenance of "double gigabit" networks. Xiamen, Fujian, Shenzhen, Guangdong, etc. give each household about 100 yuan subsidies for newly upgraded home broadband users and newly upgraded FTTR users of basic telecommunications enterprises, and give special awards to the winning projects of "Guanghua Cup" application innovation competition; Qingdao, Shandong, yingtan, Jiangxi and Jiuquan, Gansu arranged special funds to support the construction and upgrading of 10G-PON ports, Gigabit optical cats and 5G base stations.

　　Some gigabit cities have strictly implemented compensation policies for the relocation or damage of telecommunications facilities caused by municipal construction, land acquisition and demolition. Zhengzhou, Henan Province, provided funds for the communication transformation of overhead lines, communication transformation of old communities, subway construction and other engineering projects and put them in place in time; Lianyungang, Jiangsu, compensated the mobile base station site, pole road and pipeline, and the amount of compensation accounted for more than 25% of the expenses needed for restoration and construction.

　　(C) to strengthen the "double Gigabit" network construction organization and guarantee

　　Some gigabit cities have established a multi-departmental joint working mechanism led by the main leaders of the municipal government or relevant departments, and incorporated the key indicators of "double gigabit" into the important assessment contents of all districts, counties and departments. Jiaxing, Zhejiang, Yulin, Shaanxi, Dongying, Shandong, etc. set up a 5G network construction leading group headed by the main leaders of the municipal government to coordinate and dispatch the city’s 5G development; Xuzhou, Jiangsu Province established a joint meeting mechanism for 5G construction and application work, and included key indicators of "double gigabit" construction such as 5G base stations and broadband download rates into the assessment of high-quality development of cities and counties; Chongqing Yubei will incorporate the construction and application of 5G into the annual assessment of various departments, towns and streets.

　　Some gigabit cities have established key supervision mechanisms for difficult station sites, public facilities opening, and power approval. Zhangjiakou, Hebei Province supervises all districts, counties and departments to give key protection to the "double gigabit" network construction in terms of land, power connection, energy consumption indicators, municipal facilities and other resource elements; Sanya, Hainan has listed the construction of Gigabit city as the key supervision item of the municipal government, and promoted the construction of "double Gigabit" network with a series of measures such as "special work class", "financial subsidy" and "list of problems".

　　In addition, mega cities such as Hefei, Anhui, Karamay, Xinjiang and Yibin, Sichuan actively innovate ways and means, and give strong support to the development of "Double Gigabit" network from the aspects of talent introduction, characteristic application and popular science propaganda.

　　CCTV News:After a 26-hour long-distance escort, on the afternoon of 26th, 57 suspects involved in the smuggling of second-hand cars investigated by Huangpu Customs all arrived in Dongguan. At this point, a criminal network chain that specializes in smuggling used cars has been successfully cut off.

　　At 6: 00 a.m. on July 25th, Huangpu Customs and Dongguan Public Security Bureau dispatched 546 police officers, and simultaneously launched network closing operations in 16 places including Yunnan, Beijing, Tianjin and Shanghai. 24 places involved were investigated and 138 smuggled vehicles were seized on the spot.

　　The reporter followed the action group to arrest five major suspects, including Mao Moumou, at a second-hand car transfer station reported by Ruili Sister, and seized a large number of second-hand cars suspected of smuggling and fake license plates used for smuggling vehicles on the spot.

　　Huangpu Customs belongs to Shen Dongliang of Taiping Customs Anti-smuggling Branch.: "After the vehicles are modified through this transfer station, they will be smuggled and imported into China."

　　After careful management, the customs anti-smuggling personnel found that the smuggling gangs in Ruili, Yunnan Province, headed by San Mou and Wang Mohu, purchased old used cars of Volkswagen Beetle, BMW MINI and Toyota from Japan, Myanmar and other places, smuggled them into the country through the China-Myanmar border detour, and sold them to the whole country after transit in the mainland.

　　Huangpu Customs belongs to Wurui, the anti-smuggling branch of Changping Customs.On the one hand, they are used for collection, and some may be used for commercial display.

　　In addition, anti-smuggling personnel introduced that there are some domestic customers who directly take a deck of cards and drive directly on the road after buying used cars. It is understood that the Chinese government prohibits the import of used motor vehicles. The quality of illegally imported second-hand cars is generally not guaranteed. Some of them look new on the outside, but there may be various quality problems inside, and some of them are even refurbished from scrapped cars.

　　Huangpu Customs belongs to Wurui, the anti-smuggling branch of Changping Customs.: "Used cars have great hidden dangers in emissions and safety, which may cause traffic accidents if they are on the road."

　　Up to now, all 57 suspects involved in the case have been arrested.

CCTV News:What should I do when there is a minor traffic accident? At the press conference of the Ministry of Public Security today (April 7), the relevant person in charge of the Ministry of Public Security said that on the basis of the existing quick compensation, a video of a minor traffic accident will be launched from June 1, which is more convenient for the masses.

In recent years, the Ministry of Public Security has comprehensively implemented quick compensation for minor accidents nationwide.

Li Zhe, Director of Accident Prevention and Handling Guidance Department of Traffic Management Bureau of Ministry of Public Security:The video of minor traffic accidents is an upgraded version based on video calling technology and the original work of quick compensation for minor traffic accidents. It is mainly aimed at the situation that the parties need to take photos and upload information themselves in the current work of quick compensation for minor traffic accidents, and the procedures are relatively cumbersome. In addition, some parties will have concerns when they don’t see the police, and they will not withdraw from the scene.

In response to these problems reflected by the masses, the Ministry of Public Security will pilot the implementation of video speedpost for minor traffic accidents in some large and medium-sized cities by stages. The parties involved in the accident can handle the video alarm through "Traffic Management 12123" or the local express App, or call 110 or 122 to call the police, and then the alarm center will guide them to use the video express.

Li Zhe, Director of Accident Prevention and Handling Guidance Department of Traffic Management Bureau of Ministry of Public Security:In this process, there are police officers who complete the information collection, uploading and evidence fixation, and then guide the parties to the traffic accident to evacuate the scene. Through this measure, the handling process of traffic accidents can be greatly simplified, and minor traffic accidents can be fixed and evacuated from the scene within 5 minutes.

Compared with the fact that the parties involved in the accident need to wait for the police at the scene or drive to the offline express center for treatment, the video express can complete the treatment of minor accidents in just a few minutes, which reduces the waiting and round-trip time of the masses. At the same time, fast video can also effectively reduce the traffic congestion caused by accidents and the probability of secondary accidents.

In daily life, many people may have experienced such a situation: when walking, their knees suddenly "softened" and they felt as if they were going to fall. Although this phenomenon is common, it may make people feel confused and worried.

So, what is the sudden "softness" of the knee? Let’s discuss the possible reasons together.

01.

Basic structure and function of knee joint

Knee joint is one of the largest and most complicated joints in human body, which is composed of femur, tibia and patella (also known as kneecap). There are many ligaments, tendons and muscles around it to maintain its stability and flexibility.

Different parts of the knee joint cooperate with each other to complete a variety of complex activities such as walking, running and jumping.

▲ The picture comes from the Internet.

.

Possible reasons for sudden "softness" of the knee

1. Muscle fatigue

Standing or walking for a long time, especially without adequate rest, the muscles around the knee joint may be tired, leading to instant powerlessness, which is usually relieved after a short rest.

2. Ligament relaxation or injury

Ligaments around the knee joint (such as anterior cruciate ligament, posterior cruciate ligament, etc.) are responsible for maintaining joint stability. If the ligament is slack or injured, it may cause the knee joint to lose its stability instantly and feel "soft". Ligament injury is common in athletes or people engaged in high-intensity physical labor.

3. Meniscus injury

Meniscus is a soft tissue structure in the knee joint, which plays a role in buffering and stabilizing the joint. If the meniscus is injured or torn, it may lead to stagnation or powerlessness when the knee joint moves. Meniscus injury is common in sudden twisting of the knee joint, such as badminton, basketball, football and other sports.

4. chondromalacia patellae

Chondromalacia patellae refers to the degeneration and injury of patellar cartilage, which is common in young athletes or people who have been engaged in weight-bearing activities of knee joint for a long time. Patients may feel sudden weakness in their knees when walking or going up and down stairs. The occurrence of chondromalacia patellae is related to knee joint degeneration, excessive use of knee joint, knee joint trauma and other factors.

5. Neurological factors

The movement of the knee joint is controlled by the nervous system. If the nerve is compressed or damaged (such as lumbar disc herniation compressing the nerve), it may affect the activity of the knee joint, resulting in a sudden feeling of "softness". Lumbar disc herniation is common in sedentary and long-term load-bearing people.

6. Arthritis

Chronic joint diseases such as osteoarthritis or rheumatoid arthritis may also lead to the decline of the stability of the knee joint, resulting in instant weakness. Osteoarthritis is more common in the elderly, while rheumatoid arthritis can occur at any age.

If the knee is often "soft" when walking, we should first consider meniscus injury and patella softening.

.

How to deal with the sudden "softness" of the knee?

Step 1 take a proper rest

If it is caused by muscle fatigue, it is recommended to take a proper rest and avoid standing or walking for a long time. You can relieve fatigue by raising your legs and applying hot compress.

Step 2 strengthen exercise

Proper muscle strength training (such as quadriceps and hamstring exercises) can enhance the stability of the knee joint and prevent the occurrence of powerlessness.

Common exercise methods include:

Squat: It is helpful to strengthen quadriceps femoris and hip muscles, and people with patellofemoral joint diseases should be carried out under the guidance of doctors.

Straight leg lifting exercise: enhance the stability of knee joint through leg strength training.

Step 3 wear knee pads

Knee pads can be worn to provide extra support and protection during strenuous exercise or long walking. Knee pads can help stabilize the knee joint and reduce the risk of injury.

4. Maintain a healthy weight

Excessive weight will increase the burden on the knee joint, and maintaining a healthy weight will help reduce the pressure on the knee joint and prevent related problems. You can maintain your weight through a reasonable diet and proper exercise.

5. Pay attention to posture and movements

In daily life, paying attention to correct posture and movements can reduce the risk of knee joint injury. For example, avoid keeping the same posture for a long time, avoid sudden and strenuous exercise, etc.

Protect your knees. You can do this.

In order to better protect the knee joint, we can take the following measures:

Step 1 eat reasonably

Diet should be rich in protein, vitamins and minerals, especially calcium, vitamin D and collagen, which helps to maintain the health of bones and joints.

2. Exercise moderately

Proper aerobic exercise (such as walking, swimming, cycling, etc.) can enhance cardiopulmonary function and improve the flexibility and stability of joints. At the same time, avoid excessive exercise, especially exercise that has great pressure on the knee joint.

3. Maintain good living habits

Quit smoking and limit alcohol to avoid the influence of bad living habits on health. Smoking and excessive drinking may affect the health of bones and joints.

4. Regular physical examination

Regular physical examination, especially for people at risk of knee joint disease, can find problems early and take timely measures.

Step 5 wear the right shoes

Wearing suitable shoes can provide good support and cushioning and reduce the impact on the knee joint. Choose shoes with soft soles and good support, and avoid high heels and shoes with hard soles.

In daily life, we should pay attention to the health care of knee joint and take active preventive measures to reduce the occurrence of knee joint diseases. Through scientific exercise, reasonable diet and good living habits, we can effectively improve the health level of the knee joint and enjoy a healthier and more fulfilling life.

Title: Join hands to protect the Yangtze River

Introduction: The Yangtze River is our mother river. She witnessed the development and changes of the city, so I painted the Yangtze River like a mother to protect our growth! My mother told me that Yueyang, my hometown, is near the Dongting Lake and the Yangtze River. Under the common protection of everyone, besides the Yueyang Tower with a long history, the smile of finless porpoise, the beautiful images of elk and the songs of migratory birds have become our new business cards in Yueyang, so I drew them all into the painting. In color, the painting skills of re-hooking shallow painting and gradual color change are adopted, which highlights the hierarchical change of color! The anthropomorphic expression of the mother river has further enhanced our awareness of environmental protection and called on everyone to join hands to protect the mother river!
