On August 31, it was learned that the Ministry of Industry and Information Technology publicly solicited opinions on the "Regulations on the Management of Communication Short Messages and Voice Call Services (Draft for Comment)".

The exposure draft proposes that,

No organization or individual may send commercial short messages or make commercial phone calls to users without their consent or request, or if users explicitly refuse.

If the user does not explicitly agree, it shall be regarded as refusal.

If the user expressly refuses to receive after agreeing, it shall stop.

When a short message service provider sends a port-type commercial short message, it shall ensure that the relevant user has agreed or requested to receive it, and keep the user consent certificate for at least five months.

Short message service providers shall not change the use of telecommunication network code number without authorization, and shall not use the port for sending business management and service short messages for sending commercial short messages, and shall not restrict users from receiving business management or service short messages without justifiable reasons.

In addition, the Ministry of Industry and Information Technology will organize the establishment of a national unified "call rejection" platform to guide relevant organizations or individuals to respect users’ wishes and standardize commercial calls. Operators of basic telecommunications services should rely on the "call rejection" platform to provide "call rejection" services, register users’ willingness to receive commercial calls in a convenient and effective way, and provide anti-intrusion services according to users’ wishes and agreements between the two parties.

Regarding user complaints, the draft for comments was put forward.

The Ministry of Industry and Information Technology entrusts internet society of china 12321 Network Bad and Spam Reporting Acceptance Center (hereinafter referred to as 12321 Acceptance Center) to accept users’ complaints about short message service or voice call service.

　　The five-year-old baby who has not wet the bed for a long time suddenly "draws a map" frequently at night. Is it because of drinking too much water or kidney problems? The answer is beyond Bao Ma’s expectation — — All this is actually snoring.

　　Case playback

　　Came to the otorhinolaryngology department because of bedwetting

　　Cong Cong is a lively and lovely five-year-old boy, but in recent months, Cong Cong, who has long stopped wetting the bed, suddenly began to wet the bed again. At first, my mother didn’t care, just told Cong Cong to go to the toilet before going to sleep, but bed wetting still appeared from time to time, and Cong Cong often couldn’t wake up in the morning. My mother began to worry, and she took Cong Cong to the hospital in a hurry.

　　After arriving at the hospital, they went to urology and nephrology, and found no problems. Finally, under the recommendation of these two doctors, they came to otorhinolaryngology head and neck surgery.

　　When I came here, the first question the doctor asked turned out to be: "Does the child snore when sleeping?" Congcong’s mother replied, "Yes, there is snoring, but is it related to bed wetting?" The doctor explained in no hurry that snoring does have something to do with bed wetting. These two symptoms seem unrelated, but in fact, many children’s bed wetting at night is caused by snoring.

　　How does snoring trigger bed wetting?

　　Under normal circumstances, we don’t snore when we sleep. However, if the upper airway of the nasal cavity or throat is locally narrowed for various reasons, when breathing, the airflow passes through the narrow place, and the muscles are vibrated to make a snoring sound.

　　Medically, this disease is called "obstructive sleep apnea hypopnea syndrome". The main manifestations of this kind of diseases are sleep snoring, mouth breathing and breath holding. What is more frightening than snoring is that children can’t breathe enough air when they sleep because of local stenosis such as nasal cavity or throat, which leads to insufficient oxygen supply. Over time, chronic hypoxia will affect children’s development in all aspects.

　　So, how does snoring cause bed wetting? Bedwetting is medically called nocturnal enuresis, which means that children over 5 years old involuntarily urinate at night. At present, its etiology is not clear, but many research reports show that it is related to obstructive sleep apnea hypopnea syndrome. Mainly, this disease can cause children to suffer from chronic hypoxia, resulting in oxidative stress reaction, leading to bladder instability and enuresis. At the same time, obstructive sleep apnea hypopnea syndrome can cause sympathetic nerve excitation, lead to a large number of catecholamine compounds accumulation, and eventually lead to nocturnal enuresis.

　　Due to the long-term lack of oxygen supply, children’s behavior and growth and development will be affected to some extent. In addition, due to long-term oral breathing, the impact of airflow on the hard palate will deform and arch the hard palate, and the development of the oral cavity and maxillofacial region will also change over time. Gradually, children will have short and thick upper lip, high arch of hard palate, irregular teeth arrangement, prominent upper incisors, difficult facial muscles to move, lack of expression, etc. This is the "adenoid face" that is widely concerned by parents at present.

　　Remember to see a doctor when your child has these symptoms.

　　Remind parents and friends that children snore, don’t underestimate them, and don’t think that children are just "tired of playing" or sleeping soundly.

　　Some children show short-term apnea, and parents can find that although the child is still breathing in the chest and abdomen while sleeping, there is no airflow through the mouth and nose. There are also some children who have no apnea, but their breathing during long-term sleep is in a state of insufficient ventilation. In the long run, children’s lack of ventilation at night and disordered sleep structure will cause a series of pathophysiological changes.

　　Children who snore often find it difficult to get up in the morning, often feel sleepy during the day, lack of concentration and hyperactivity, poor memory, learning difficulties, or nocturnal enuresis, growth retardation, hypertension, obesity, etc., and even some children may have psychological and behavioral abnormalities, such as abnormal shyness, rebellion or aggressive behavior. If the child often snores in sleep, or is accompanied by breathing with his mouth open, holding his breath at night, wetting the bed, etc., parents should take the child to the otorhinolaryngology head and neck surgery.

　　At present, the clinical diagnosis and treatment of obstructive sleep apnea hypopnea syndrome is very mature, and many children have achieved satisfactory results after drug treatment or surgical treatment. Timely diagnosis and treatment can not only restore children’s healthy and happy childhood as soon as possible, but also avoid various complications.

In recent years, due to the change of people’s lifestyle, the incidence of stomach diseases is increasing year by year. At present, about 70% of the general population suffers from stomach diseases, and it shows a trend of younger age.

At the turn of the season, it is the high incidence season of stomach diseases. On the one hand, the heat in summer has not completely faded away, and people often don’t avoid cold food. On the other hand, the weather is getting colder, the temperature difference between day and night is large, and the gastrointestinal function is weakened, so it is easy to suffer from gastrointestinal diseases. Huang Feijian, an expert in internal medicine at Dongcheng Hospital of Traditional Chinese Medicine, said that people should pay special attention to the acquired protection of the spleen and stomach and try to avoid chilled drinks and foods in summer.

Gastropathy mostly develops from chronic superficial gastritis.

As mentioned in Huangdi Neijing, the spleen and stomach are the sea of water valleys. Only when the spleen and stomach are good, what we eat can be digested and absorbed normally, and then we can study and live energetically. If the digestion is not good, the human body may have a series of problems such as hypoxia and ischemia, which may lead to dizziness and weakness in walking, and even more serious diseases such as enteritis and heart disease. Therefore, it is very important to protect the spleen and stomach.

In today’s era, common stomach diseases include chronic superficial gastritis, chronic congestive gastritis, chronic antritis, chronic erosive gastritis, chronic esophageal reflux gastritis, bile reflux gastritis, chronic atrophic gastritis, gastric ulcer, intestinal ulcer and colitis. Among them, chronic superficial gastritis, atrophic gastritis and gastric ulcer are common diseases in our lives. In recent years, with the increasing pressure of life, people’s irregular eating habits and lifestyle changes, more and more people suffer from such stomach diseases.

Huang Feijian said that chronic superficial gastritis can be said to be the basic gastritis of all stomach diseases, and there are many patients. From the perspective of traditional Chinese medicine, chronic superficial gastritis is related to cold pathogen or damp pathogen, and the main symptoms include flatulence, bowel sounds, abdominal sounds, and unpleasant diet. If it is a stomach disease caused by cold and dampness, the main symptoms are noisy and restless stomach, flatulence, acid regurgitation, slight vomiting and constipation, and there will be cases where the symptoms are aggravated by eating cold things and slightly relieved by eating hot ones. After wet and cold stasis appear in the body, the body will have symptoms such as fear of heat, dry mouth, dizziness, insomnia, palpitation, shortness of breath and even high blood pressure.

Among many stomach diseases, chronic superficial gastritis is a mild and easy-to-treat disease, but it should be found and treated early. For chronic superficial gastritis, the treatment of traditional Chinese medicine focuses on promoting blood circulation and removing blood stasis on the basis of dispelling cold, dehumidification and strengthening the body resistance. The medicine contains Erchen decoction, Huaqi decoction and Lizhong decoction.

Attention should be paid to the fact that gastric ulcer and atrophic gastritis can induce cancer.

Gastric ulcer and atrophic gastritis are concepts of western medicine. Among them, the symptoms of gastric ulcer are applicable to the category of epigastric pain in traditional Chinese medicine, and the lesions are mostly in the upper abdomen, and may also appear in the left upper abdomen or behind the sternum and xiphoid process. Patients often feel dull pain, dull pain, distending pain, burning pain, bloating, fullness, anorexia, indigestion, poor diet or inability to eat. In life, overeating sweets is usually one of the causes of gastric ulcer. The stomach can’t digest and metabolize a lot of sweets completely, and it accumulates in the stomach, which in turn leads to gastric ulcer.

Patients with gastric ulcer often have their symptoms relieved or disappeared after meals. The pain is obvious from half an hour to an hour after meals, and gradually relieved after 1-2 hours, and the pain is aggravated at night. The pain gets worse after catching cold, overeating and drinking. Some patients also have nausea, vomiting, acid regurgitation, belching and diarrhea, and some patients may have no symptoms or take complications such as bleeding and perforation as the first symptom. Gastric ulcer can lead to perforation of ulcer, upper gastrointestinal bleeding, and long-term attack can easily lead to gastric cancer.

Atrophic gastritis, also known as chronic atrophic gastritis, is a chronic digestive system disease characterized by atrophy and reduction of gastric mucosa epithelium and glands, thinning of gastric mucosa, thickening of mucosal base, or metaplasia of pyloric gland and intestinal gland, or atypical hyperplasia. Often manifested as dull pain in the upper abdomen, fullness, belching, loss of appetite, emaciation, anemia, etc., it is a multi-pathogenic disease. According to data observation, if atrophic gastritis is not treated in time, the canceration rate is quite high. In the treatment of traditional Chinese medicine, atrophic gastritis mainly focuses on relieving qi, strengthening the body resistance, supplementing qi and blood, and improving immunity, and on this basis, it clears up the environment for the growth of Helicobacter pylori. It can be cured in a month or two or three months.

Gastric ulcer and atrophic gastritis can occur independently or simultaneously. Gastric ulcer disease occurs on the basis of chronic gastritis, and many patients with gastric ulcer have chronic atrophic gastritis.

Look, hear and ask questions, and intervene according to the symptoms

Traditional Chinese medicine believes that six evils and seven emotions are both factors leading to atrophic gastritis of gastric ulcer. Most patients with gastric ulcer and atrophic gastritis have white, thick and greasy tongue coating, heavy and astringent pulse, and the pulse is full of yang, and the yin and cold are heavy, which leads to the breeding of Helicobacter pylori. The principle of Chinese medicine in treating diseases is not to directly kill Helicobacter pylori, but to regulate the body itself and fundamentally change the breeding environment of Helicobacter pylori, so that there is no soil for Helicobacter pylori to breed again.

Therefore, whether it is gastric ulcer or atrophic gastritis, it is necessary to find out the cause according to the patient’s pulse, tongue and face, and distinguish which constitution the patient belongs to, cold, dampness, cold and dampness, or stasis. After the diagnosis, the problem can be fundamentally solved by targeted treatment according to the lesions and symptoms.

Diet and life management are indispensable for the treatment of old stomach diseases.

It is very important to protect the temperature of the stomach for patients with gastric ulcer and atrophic gastritis. Diet should be warm, soft, light, vegetarian and fresh, so as to achieve regular quantitative, eat less and eat more meals, do not eat hot, hard, too spicy, too sticky food, but also avoid overeating, smoking and drinking. Under the guidance of a doctor, we should avoid taking drugs that irritate the stomach, and pay attention to the method of taking them, preferably half an hour after meals, in order to avoid irritating the gastric mucosa and worsening the condition. In particular, you can’t eat things that are too cold often. Generally speaking, the temperature of the stomach is around 36 degrees, while the temperature of iced food is between MINUS 1 degree and MINUS 2 degrees. If you drink and eat for a long time, the temperature of the stomach will drop, which will lead to stomach diseases. Therefore, even in hot summer, all kinds of iced drinks and foods should be avoided as much as possible.

Gastric ulcer and atrophic gastritis are closely related to mood and mentality. Therefore, we should pay attention to mental health, keep cheerful and emotional stability, and avoid the stimulation of bad emotions such as tension, anxiety and anger. At the same time, the law of life, work should be combined with rest, ensure sleep, and insist on proper exercise.

■ Tips

Experts recommend traditional Chinese medicine prescription for nourishing stomach

Stomach fever: 1 gram of honeysuckle and 1 rose.

People with stomach cold: stir-fried coix seed 10 grams, Poria cocos 10 grams, 3 slices of ginger, or put a little black tea to protect the gastric mucosa.

Women with stomach fever: 1 gram of chrysanthemum and 2 grams of Bai Meihua.

Women with stomach cold: 1 rose, 2 grams of dried tangerine peel, make tea to drink.

Old people: 6 grams of Astragalus, 6 grams of Poria, make tea to drink. Or add 6 grams of Salvia Miltiorrhiza.

Flatulence: Draw a circle along the navel every night, 36 times clockwise and 36 times counterclockwise, until you have a fever.

■ Tips

Several behaviors that are easy to hurt the stomach

1. Frozen diet is prone to "gastritis"

In the hot summer, you can sweat when you sit still. Many people will gulp down a glass of cold beer or drink a bottle of frozen drink quickly in order to cool down and quench their thirst. I feel carefree, but the cold drink and cold beer I just drank will stimulate the warm stomach. Just like conditioned reflex, the gastric mucosa will contract rapidly, leading to gastric ischemia and hypoxia, which will lead to the recurrence of gastritis or gastropathy.

2. Blowing the air conditioner makes the stomach "cold"

Because of the hot weather, many people blow the air conditioner for a long time at night or blow the fan all night, and don’t cover the quilt at all. Although doing so can increase the comfort of sleep, but let the body stay in a low temperature state for a long time, which will easily make the stomach catch cold, cause stomach discomfort, nausea, bloating and other symptoms.

Irregular diet hurts the stomach the most.

If you don’t eat breakfast, you are hungry for a full meal, and your three meals are unbalanced or overeating, you can do it occasionally, but if you do this for a long time, the damage to your stomach will accumulate over time, which will cause great trouble. Especially for people who have problems with their stomachs, it is simply worse.

　　Investigation motive

　　"Delta Omicron Co-circulation", "Six Yangkang tourists in a scenic spot died of heart failure", "Beijing tap water is sunny" and "Express delivery industry closed on January 8 due to epidemic situation" … … For some time, there have been rumors about the epidemic-related network, distorting the national epidemic prevention policy, dispelling the people’s confidence in fighting the epidemic, seriously endangering social stability, and the people hate it.

　　Recently, the Central Network Information Office reported typical cases of epidemic rumors. The relevant person in charge said that it will continue to resolutely crack down on rumors and rumors, and strictly investigate and deal with account subjects who publish rumors. At the same time, relevant departments and netizens are welcome to actively participate in reporting, provide relevant clues, and work together to eradicate online rumors. Living soil.

　　Why are epidemic-related rumors repeatedly banned, why do some rumors come back after rumors, and how to effectively rectify and purify cyberspace? With these questions, the reporter conducted an in-depth investigation and interview.

　　□ Our reporter Zhang Shoukun Wen Lijuan

　　"Yangkang is not equal to health. Yesterday, several people died in Laojunding skiing, all of them were Yangkang, and suddenly they suffered from heart failure after strenuous exercise." Recently, the net spread "Qinhuangdao Laojunding Scenic Area ‘ Yangkang ’ The information that 6 tourists died of heart failure has attracted attention. After investigation, the news was false information. At present, the rumored woman Ma has been administratively detained by the police.

　　From "killing the whole city tonight" to "increasing chlorine injection into tap water", from "nucleic acid sampling is toxic" to "mask raw materials will cause pulmonary nodules", from "a positive man is transferred by crane" to "a container is used to operate a positive patient somewhere", from "the tap water will spread the virus" to "you can choose a mild strain to infect and produce antibodies" … …

　　In the investigation, the reporter of "Rule of Law Daily" found that every once in a while, all kinds of epidemic-related rumors circulating on the Internet will be "updated". Some of them deliberately misinterpret and fabricate epidemic prevention policies, and some carry out pseudo-popular science under the guise of science. Because they are related to the epidemic situation, these rumors can easily attract people’s attention and get a lot of attention and forwarding, which leads to many people’s doubts, anxiety, panic and other emotions, and even interferes with the normal epidemic prevention and control work.

　　A number of interviewed experts said that to rectify online rumors and purify cyberspace, we must further compact the platform responsibility, improve the information review and judgment mechanism, and control the release of epidemic-related rumors at the source; It is necessary to severely punish rumors according to law, and if serious consequences are caused, criminal punishment will be given.

　　Internet rumors about epidemic diseases continue.

　　Rumors make money by draining.

　　On New Year’s Day this year, Yin Kang, a citizen of Lianyungang City, Jiangsu Province, who opened the social software early in the morning, found that there were several rumors that had been continuously refuted in his social group and circle of friends.

　　At the end of the holiday, when I went to work, some colleagues told Yin Kang mysteriously with a bottle of Erguotou, that high alcohol can prevent COVID-19 infection. Would you like some? What bothers Yin Kang even more is that grandpa, who had given up smoking and drinking because of his poor liver and lungs, immediately asked his family to smoke and drink … …

　　Yin Kang said that although there are many rumors like this, people with discerning eyes know that they are false at first glance, but because of the rapid spread and wide range, some people, especially many elderly people, are willing to believe it. In addition, there are still many rumors that are cloaked in science, and the tone is so convincing that it is difficult for ordinary people to distinguish them.

　　Not long ago, WeChat Security Center announced the top ten rumors that were most widely circulated in the circle of friends in 2022, many of which were related to the epidemic situation, such as the toxic reagent on the "sampling cotton swab", the daily subsidy during the epidemic, and the prevention of Covid-19 by soaking Stephania in water. For Pan Ying in Nantong City, Jiangsu Province, these rumors are familiar to her.

　　"These top ten rumors have been forwarded by my family elders to the group. In recent years, I have been on the road of rumors, and I have tried my best to tell my family that these are false, but rumors have always existed, especially about the epidemic. This rumor has come again, and some rumors that have been rumored will come back after a while, and every rumor, no matter how outrageous, will always be believed by my family." Pan Ying said.

　　Recently, news about Covid-19 Omicron mutant XBB has been rampant. The latest news shows that the introduction of a new strain XBB.1.5 has been detected in Shanghai. At present, there are many rumors about XBB.1.5 on the Internet, especially a screen shot circulating on the Internet platform, saying that all the strains prevalent in China are the younger brother of XBB.1.5, which mainly focuses on cardiovascular and cerebrovascular diseases and will cause diarrhea. It is suggested that the public prepare montmorillonite powder, norfloxacin, rehydration salts, probiotics and so on. Shanghai rumor platform said that the screenshot exaggerated the pathogenicity of XBB.1.5, and did not rule out people with ulterior motives to promote products. Many doctors have warned not to take montmorillonite powder, norfloxacin and other drugs as mentioned in the screenshot at will.

　　In the investigation, the reporter found that since the epidemic prevention and control work was carried out, all kinds of information about the prevention and control of COVID-19 infection have always occupied an eye-catching position on social apps, websites and other network platforms, including many old and new rumors. Moreover, the rumors related to the epidemic have different distribution characteristics in different stages of the epidemic development, reflecting the changes in public sentiment and demand, which may make people have a wrong understanding of COVID-19 infection and adopt wrong means in the process of preventing and treating COVID-19, thus affecting the normal epidemic prevention and control work.

　　The Public Opinion Center of the Rule of Law Network conducted a public opinion analysis on Internet rumors about epidemic diseases caused by high fever, and found that social platforms have become a "Petri dish" for rumors about epidemic diseases. Most rumors about epidemic diseases come from social platforms and spread mainly through chat groups, friends circle, WeChat official account and video numbers, among which chat groups and friends circle are the main positions for communication. This is because the "strong relationship" social circle has the characteristics of privacy, closure, agglomeration, etc. The privacy of the acquaintance relationship chain makes it difficult to track the process of information production and forwarding, and at the same time, the credibility and forwarding volume of rumors are greatly increased, thus achieving cross-group and cross-platform communication. In addition, all kinds of short video platforms have become the new "source" of online rumors. The presence and authenticity of short videos increase the persuasiveness of rumors and often mislead the public to believe them.

　　Why are some publishers keen to fabricate rumors? The Network Security Bureau of the Ministry of Public Security has revealed this, and there will be advertisements inserted under the content released by the rumors or in the comment area. The more traffic advertisers are exposed and clicked, the more revenue they will get. "It can be said that every time you click, the rumor maker can make money."

　　Yin Kang said that many of his friends and family members feel that forwarding this information at will can remind more people, and it is a positive energy behavior. Even if it is false, it will not cause any losses to others. As a result, it has become a disseminator who has expanded the scope of rumors unconsciously.

　　Hair under the guise of official name

　　The platform is responsible for governance.

　　Recently, a notice claiming to be from "President of Changzhou Red Cross Society" spread widely. According to the notice, if brown sugar, ginger, scallion and garlic are boiled in water, the probability of being infected with the virus is almost zero. Li Lei of Heze City, Shandong Province has also received an "anti-epidemic prescription" from his old mother at home. However, Li Lei’s online verification found that the screenshot had been spread on the Internet as early as February 2020. At that time, the staff of Changzhou Red Cross Society rumored that the organization and the president had not released the above information.

　　"Most of them can be seen as rumors at a glance, and even a large part of them have been rumored by the government and proved to be rumors. I wonder why many rumors have been repeatedly banned, and some people are convinced of the rumors that have been rumored." Li Lei said.

　　Pan Ying said that she saw many rumors, all of which were published under the guise of official organizations. "I used to receive short messages informing me of nucleic acid testing and the health code turning red, which said that they were sent by the CDC and left a phone number. Some of them were true and some were false, so many people were cheated, which led me to doubt their authenticity as long as I saw the epidemic-related text messages now."

　　"There are too many rumors. We may remember them for a while after rumors, but we are not professionals. Most people may forget them in a month or two, and it is difficult to distinguish similar rumors when they come again." Pan Ying said.

　　According to Li Junhui, a special researcher at the Intellectual Property Research Center of China University of Political Science and Law, there are three main reasons for the repeated prohibition of epidemic-related rumors. First, epidemic-related information is the focus of public attention, which is related to the individual’s concern about how to avoid being infected and how to deal with it after infection. Second, it is related to the insufficient, untimely and incomplete release of epidemic-related information in some areas, because real information can not meet or solve public concerns, and it will naturally be attracted by some false information; Third, the information of epidemic-related rumors has the characteristics of confirmation, illustration or difficulty in distinguishing authenticity, which makes the relevant information easily misinformed and further misinformed.

　　What kind of responsibility may the rumor-monger bear for spreading rumors about the epidemic?

　　Ai Hongqiang, a lawyer of Beijing Jingshi (Quanzhou) Law Firm, told reporters that according to the Law on Public Security Administration Punishment, those who spread rumors, lied about dangerous situations, epidemics, police situations or deliberately disturbed public order by other means will face detention and fines. If a citizen’s personal reputation right is infringed by spreading rumors, according to relevant regulations, the infringer will bear the responsibility of stopping the infringement, restoring the reputation, eliminating the influence, apologizing and compensating for the losses. In addition, making and spreading epidemic rumors may also bear criminal responsibility.

　　At the end of November last year, the Central Network Information Office reported that in view of the recent rumors in the fields of epidemic prevention and control, emergencies, and people’s livelihood, it urged and guided the website platform to strengthen monitoring and verification, and the key website platforms handled more than 5,400 accounts for spreading rumors on the Internet, which was the first time. Trace the source and close the initial account.

　　Experts interviewed by reporters believe that the network platform has an unshirkable responsibility for the governance of epidemic-related information.

　　Li Junhui believes that the network platform should classify information, and make clear what belongs to the simple sharing of individual experiences and what belongs to the misleading information release. For all kinds of information released by users on the platform, a review and judgment mechanism should be established in time, and the experience sharing review with high similarity in information content should be strengthened to avoid spreading false epidemic-related information and causing public panic. For the release of rescue information, it is necessary to ensure that the rescue information can be released normally, and also to prevent criminals from simply copying and applying other people’s help information for release, which will affect public judgment.

　　The relevant staff of Tik Tok Platform told reporters that recently, during routine inspections, the platform found that a very small number of users posted content without medical basis, such as "COVID-19’s remedies for reducing fever — — Boiled soybean water to drink ","Smoked mugwort leaves and moxa sticks can wipe out Covid-19 ","Never eat food when you have a fever, including eggs and milk "and so on. The above contents have been refuted by authoritative media and medical experts. In this regard, the platform has given a continuous blow and treatment. Since November 2022, the platform has handled 332,600 false videos related to the epidemic and marked more than 200,000 suspicious contents.

　　Timely release of authoritative information

　　Crack down on epidemic rumors according to law

　　Recently, Shanghai Rumor-dispelling Platform has sorted out the recent rumors, classified them according to four major themes: prevention, symptoms, treatment and life, and attached suggestions and opinions from medical experts and authoritative organizations, hoping to present a practical "prevention and control book" for the public.

　　The reporter found that by searching for "epidemic situation" or switching to the "anti-epidemic" column on Tik Tok’s homepage, users can enter the epidemic prevention rumor area in Tik Tok and check the relevant knowledge; When Baidu searches with keywords such as "COVID-19" and "epidemic situation", there will also be a rumor-dispelling area and a national epidemic prevention hot search list to give users more scientific guidance.

　　The relevant departments have been taking action to crack down on rumors related to the epidemic.

　　Publishing and spreading false epidemic-related information through the Internet and deliberately creating and spreading epidemic-related rumors have seriously affected the normal public order. Hubei public security organs severely cracked down according to law and seriously investigated the relevant legal responsibilities of publishers, forwarders, group owners, administrators and other personnel.

　　On October 8, 2022, Huang, a citizen of Jianli City, Hubei Province, spread rumors about the epidemic in many social groups. Hu, a citizen of the city, forwarded it to his personal short video account without verification and spread again. The behavior of the two people caused panic among local residents and caused adverse effects. The Hongcheng Police Station in Jianli City organized a police investigation, quickly found the communicators Huang and Hu, and carried out legal education for them. The two clarified the rumor. In the end, the violator Huang was sentenced to five days’ administrative detention and Hu was sentenced to a fine of 200 yuan.

　　In November last year, the Network Information Office of Yulin Municipal Committee of the Communist Party of China and the Public Security Bureau of Yulin City of Shaanxi Province issued the Notice on Combating and Rectifying Internet Rumors Related to the Epidemic in accordance with the Law, prohibiting the compilation and distribution of false information and resolutely resisting online rumors. Website platforms, media people and Internet group administrators should strictly review the sources and contents of information related to the epidemic. If publishing and disseminating false information through the Internet has caused serious social impact, online letters and public security organs will crack down on relevant websites, platforms and Internet accounts according to laws and regulations.

　　Recently, Jiujiang City, Jiangxi Province officially issued a notice, and the information related to the epidemic is subject to the official information released by the epidemic prevention and control headquarters at all levels in the city. For the information related to the epidemic that has not been officially confirmed, it is not published, disseminated, commented, believed, rumored or spread. What has been published should be deleted immediately to actively eliminate the adverse social impact. If it cannot be deleted, it is necessary to promptly dispel rumors and take the initiative to explain the situation to the public.

　　According to Hu Gang, Deputy Secretary-General of internet society of china Legal Work Committee, at present, China has built a legal system of epidemic reporting, notification and publication, which is mainly based on the law on the prevention and control of infectious diseases and emergency regulations for public health emergencies, and a legal system of online rumor management, which is mainly based on the Civil Code, the Criminal Law, the Law on Public Security Administration Punishment, the E-commerce Law, the Network Security Law, and the Internet information service management measures, and has continuously carried out special actions such as "clearing and cracking down on online rumors and false information" to supervise the website platform to effectively perform information content management.

　　How can we make the rumors about the epidemic no longer "outcrop"?

　　Li Junhui said that in order to accurately crack down on false or rumor information related to the epidemic, it is necessary to have real and scientific information release subjects or strengthen the linkage between the regulatory authorities and platforms, and subjects with information screening ability and conditions should participate in the review of information release on various platforms to control rumor information release from the source. In addition, it is necessary to strengthen the big data analysis of information released by users, refine the focus of users’ attention, and timely release authoritative information to respond, so as to relieve or reduce public concerns. Those who are suspected of deliberately creating and spreading false information shall be investigated for legal responsibility according to law.

　　Hu Gang suggested that the early warning system of infectious diseases and the information disclosure system of infectious diseases should be improved, and the national information on legal infectious diseases should be regularly published by China CDC, and the disease control institutions at or above the county level should regularly publish information on legal infectious diseases in their respective administrative regions. When an infectious disease breaks out and is prevalent, the competent health department of the local people’s government at or above the county level shall publish the epidemic information within its administrative area; When infectious diseases break out and spread across provinces, the competent department of health in the State Council shall be responsible for the announcement. At the same time, to improve the website platform’s ability to accurately control the rumors of epidemic-related networks, Internet industry associations can build information sharing and joint punishment mechanisms, and those who repeatedly maliciously publish rumors can be punished by releasing information within a limited time or prohibiting the release.

In Chinese over 60 years old, osteoporosis has reached 56%[1].

However, there is one disease that is more frequent than it-senile foot disease, the prevalence rate is as high as 87%, which seriously threatens the health of our parents [2,3].

However, only 7.3% people will take foot disease seriously and consult a doctor [4].

As the saying goes, "people get old when they are old", and when they get old, their legs and feet are awkward at first.

Time and tide wait for no man

With the increase of age, the muscle strength of the foot is weakened, the elasticity of ligaments becomes worse, or due to unsuitable shoes, it is easy to have problems such as arch collapse and hallux valgus [1-3]. As a result, the load-bearing capacity of both feet decreases.

(Made by myself)

2. Poor foot care

Old people, bad eyes, inflexible fingers, and inability to bend over will all lead to a common result-

Give up the care of your feet.

(Made by myself)

If the toenails are too long to be trimmed or washed, it may lead to problems such as too long and thick toenails and onychomycosis.

The most common foot diseases of the elderly are [6]:

Hypertrophy of toenails (41.3%)

Hallux valgus (commonly known as "big foot bone") (28.7%)

Dry skin (26.0%)

Corns and calluses (commonly known as calluses) (24.0%)

These problems will lead to a common consequence-

If you can’t walk steadily, you will fall easily.

Many elderly people are relatively fat, and their feet are heavily burdened when walking, which makes them easy to hurt, increasing the risk of falls and fractures.

Moreover, osteoporosis is a common disease in the elderly, and it is more likely to lead to hip fracture when falling-it is called "the last fracture in life" (the mortality rate of hip fracture is as high as 22%~30%, even 50%[7-9]).

American gerontologist Hazzard said: "A clear head and a pair of feet that can move freely can make the elderly live better." [5]

Inappropriate shoes are one of the reasons why the elderly fall, and more than 70% of the elderly have inappropriate shoes [10]. So, what are the main situations in which shoes are not suitable?

1. The shoes are too narrow

Toes and soles are squeezed for a long time, so that the forefoot is deformed, hallux valgus and little toe are deformed, which will be very painful.

(Made by myself)

2. The shoes are too short

It will bend the toes, which will be deformed after a long time (that is, hammer toes or claw toes).

(Made by myself)

The skin on the instep is squeezed, slowly forming a hard cocoon, which is painful and swollen.

Diabetic elderly people with poor blood sugar control are also prone to serious infections.

Let me say one thing first:

The so-called "shoes for the elderly" should be bought carefully to avoid paying the "filial piety tax".

Many "shoes for the elderly" are branded as breathable, spacious, soft, non-squeezing, and non-slip, and can even be like twisting a towel.

(Made by myself)

But in fact, the softer the shoes, the better. Shoes that can be easily twisted are easy to deform and lack support for the arch.

When buying shoes for the elderly, we should follow the principle of "wide front, tough middle and hard heel".

Specifically, the elderly should pay attention to these three points when choosing shoes:

1. The sole has anti-slip design.

Older people’s physical balance ability becomes worse, and the perception of pressure on the soles of their feet decreases, which will increase the risk of falling when walking [5].

Therefore, it is necessary to choose a non-slip design for the sole.

2. Hard soles with sufficient support

Shoes that are too soft, such as old cloth shoes, lack sufficient support at the arch, and it is easy to feel uncomfortable when walking too much, and the feet are tired, sore and painful; Encountering a gravel road will also increase the risk of falling [11,12].

Hard-soled shoes can increase the safety and stability of the elderly when walking [13].

The middle toughness of shoes should be moderate, and you can try to twist them by hand. It is not good to twist them too easily or completely.

The heel also needs to have a certain height, at least 1.5~2.5 cm, which can disperse the pressure on the sole of the foot.

3. The vamp should be breathable, warm and loose.

Old people’s feet have poor blood circulation and are prone to cold feet, pain, blue skin and other symptoms [11].

Buying a pair of breathable, warm and loose shoes is comfortable and easy to wear, and it can also reduce the incidence of nail malnutrition and fungal infection (commonly known as beriberi) [5].

It can be a little bigger, leaving about 1 cm in front of the toes, so that the toes have enough room to move.

In addition, when the elderly buy shoes, there are three tips:

1. It’s best not to buy it by children or online shopping, but to try it yourself.

Bring socks and insoles that you usually wear. Feel it on your feet and experience walking, running and jumping in the store to choose the shoes that suit you best.

It’s best to buy it in the afternoon

Affected by gravity and venous reflux, people’s feet are usually bigger in the afternoon than in the morning.

Trying on shoes in the morning will hurt your feet in the afternoon [5].

Don’t bother, try more pairs.

Old people often encounter two feet with different sizes, for example, one foot has severe hallux valgus, or the arch of both feet collapses to different degrees.

This requires trying on a few more pairs and finding shoes that are comfortable for both feet. Or put an arch support pad on a shoe.

What do you know about the custom of Dragon Boat Festival?

DUAN

erect

WU

noon

Dragon Boat Festival is one of the four traditional festivals in China.

Celebrate every year on the fifth day of the fifth lunar month.

The origins and customs are rich and varied.

Has profound cultural connotation.

The origin of Duanwu Festival

It is said that the custom of eating zongzi and racing dragon boats on the Dragon Boat Festival is to commemorate Qu Yuan, a great poet in Chinese history. It is precisely because of this that the Dragon Boat Festival was named "Poet’s Day" after the founding of New China.

In the history of our country, the saying that the Dragon Boat Festival is to commemorate Qu Yuan has a history of more than 1500 years. According to legend, after Qu Yuan threw himself into the Miluo River, the local people immediately rowed for rescue and went all the way to Dongting Lake, but Qu Yuan’s body was never seen. At that time, it was rainy, and the boats on the lake gathered together beside the pavilion on the shore. When people learned that it was to salvage the virtuous minister Dr. Qu, they went out in the rain again and rushed into the vast Dongting Lake. In order to mourn, people rowed on rivers, and then it gradually developed into a dragon boat race. The people were afraid that the fish in the river would eat his body, so they went home to bring rice balls and throw them into the river to prevent fish and shrimp from ruining Qu Yuan’s body. Later, it became the custom to eat zongzi.

The custom of Duanwu Festival

dragon boat race

Dragon boat race is the main custom of the Dragon Boat Festival. According to legend, it originated in ancient times, because Chu people could not bear to part with Qu Yuan, a worthy minister, and died in the river, many people rowed to catch up and save. They scrambled to catch up with each other until Dongting Lake disappeared. After that, I will row a dragon boat on May 5th every year to commemorate it. People use dragon boats to disperse the fish in the river so as not to eat Qu Yuan’s body. The habit of racing is prevalent in Wu, Yue and Chu.

eat Zongzi

Eating zongzi on Dragon Boat Festival is another traditional custom of Chinese residents. Zongzi, also known as "horn millet" and "tube zongzi". It has a long history and various patterns. On the morning of Dragon Boat Festival, families eat zongzi to commemorate Qu Yuan. Generally, they wrap zongzi the day before, cook them at night and eat them in the morning. Dumplings are mainly made of tender reed leaves which are abundant along the river pond, and bamboo leaves are also useful in some areas, collectively called zongye. The traditional form of zongzi is triangle, which is generally named after the inner pulp. The glutinous rice dumplings are called rice dumplings, the ones mixed with adzuki beans are called adzuki dumplings, and the ones mixed with red dates are called jujube dumplings, which are collectively called glutinous rice dumplings. Jujube dumplings are homophonic for "early middle school", so they are eaten the most, and children who intend to study can win the championship early. In the past, scholars used to eat jujube dumplings in the morning on the day of taking the imperial examination. Up to now, parents have to make jujube dumplings for candidates on the morning of the entrance examination day for middle schools and universities, wishing them a good school.

Tie colorful ropes and wear sachets.

Five-color lines are mainly composed of five colors: green, red, white, black and yellow. These five colors are called auspicious colors, and they can be worn on the Dragon Boat Festival to keep you safe. Later, the custom of tying colorful ropes gradually evolved into hanging sachets, and children wore sachets on the Dragon Boat Festival. Legend has it that it meant to ward off evil spirits and drive away plague (in ancient times, people thought that they were sick because of monsters and ghosts), but it was actually used to decorate the inner head. The sachet contains cinnabar, realgar and fragrant medicine, wrapped with silk cloth, which is full of fragrance, and then tied with five-color silk threads to form a rope, making a string in various shapes, all kinds of shapes, small and lovely. In some southern cities of China, young men and women also use sachets to express their deep love.

Hanging wormwood and calamus

A folk proverb says, "Willows are inserted in Qingming Festival, and Ai is inserted in Dragon Boat Festival". On the Dragon Boat Festival, people regard inserting wormwood and calamus as one of the important contents. Every household should sweep the courtyard and put calamus and moxa sticks in the lintel and hang them in the hall. Acorus calamus, Folium Artemisiae Argyi, Liuhua, Bulbus Allii and Dragon Boat Flower are made into human or tiger shapes, which are called Ai Ren and Ai Hu. It is made into garlands and ornaments, which are beautiful and fragrant, and women compete to wear them to drive away evil. Dragon Boat Festival is also a "health festival" handed down from ancient times. On this day, people sweep the courtyard, hang mugwort, hang calamus, sprinkle realgar water, drink realgar wine, stir up turbidity, remove rot, sterilize and prevent diseases. They are considered to have the effect of exorcising evil spirits and protecting the health and safety of family members.

Point realgar wine

Realgar is also a kind of medicinal material, which is said to kill all kinds of poisons. Therefore, during the Dragon Boat Festival, Shaanxi people will soak realgar in wine and put realgar wine on children’s ears, nose, forehead, wrists and ankles. It is said that this practice can keep mosquitoes, snakes, scorpions, centipedes, geckos and spiders off their bodies.

Eat salted duck eggs

Eating salted duck eggs on the Dragon Boat Festival is a big custom. As the saying goes, "You have to eat salted egg zongzi to send the chill." After the Dragon Boat Festival, it indicates that the hot summer is coming, and the activities of animals and plants have entered a vigorous stage. In addition, the humid climate and the active diseases, pests and bacteria are easy to cause many diseases. Eating salted duck eggs on the Dragon Boat Festival can detoxify and help keep healthy.

The contents of the Dragon Boat Festival customs are rich and varied, including polo, grass fighting, painting, flying kites, and there are some small differences in details because of different regional cultures throughout the country.

　　Guizhou University conscientiously studies and implements the important exposition of the Supreme Leader General Secretary on education and science and technology, adheres to the "four orientations" and practices the "four services", deepens the reform of scientific research organization mode, stimulates the innovation enthusiasm of scientific researchers, strives to create a new situation of high-quality development of scientific research, and helps to achieve high-level scientific and technological self-reliance.

　　Optimize the management system.The first is to improve the scientific research management system. Planning a package of scientific research management system reform, revising and promulgating more than 10 items such as "Management Measures for Vertical Scientific Research of Natural Sciences in Guizhou University (Revised)" and "Measures for Cultivating Symbolic Scientific Research Achievements of Natural Sciences in Guizhou University (Trial)", and constantly improving the institutional guarantee for scientific research layout, organization promotion and coordinated management. Set up a leading group for the transformation of scientific and technological achievements with the secretary and the principal as the team leader and the heads of relevant functional departments as members to promote the transformation of scientific and technological achievements as a whole. The second is to improve the supervision and management process. Improve the working rules of the academic Committee of the school, hold regular academic Committee meetings, dynamically adjust members, and effectively improve the effectiveness of academic governance and supervision. The scientific research work will be included in the school’s annual work points and the annual "Ten Practical Things", and the school’s supervision office will be responsible for supervising and compacting the main responsibility of scientific research work. The third is to improve the evaluation methods. Formulate the Assessment Method for Improving the Innovation Ability of Scientific Research Platform of Guizhou University (Trial) and the Graded and Classified Integral Standard for the Performance Assessment of Academic Contribution of Scientific Research of Guizhou University (Trial), explore the classified evaluation and assessment methods oriented to quality and contribution, and stimulate the vitality of scientific researchers at all levels and categories. Strengthen the application of assessment results, reasonably link the effectiveness of scientific research with professional title evaluation, post appointment, talent evaluation and performance assessment, and enhance teachers’ enthusiasm and initiative.

　　Focus on scientific research and innovation.First, take the national platform as the fulcrum to serve the national and regional major strategies. Give full play to the role of the National Key Laboratory of Green Pesticides and the National Key Laboratory of Public Big Data jointly established by the province and the Ministry, anchor the scientific and technological frontiers such as the integration, open sharing and security of green pesticides, food security and public big data, actively undertake major national projects, develop new technologies based on biological prevention and control, and crack key technologies such as data fusion, data analysis and intelligent analysis. Focusing on the strategy of "rich minerals and refined mining" in Guizhou Province, we took the lead in setting up an expert team of "manganese", "phosphorus" and "barite-fluorite", with academicians as the chief scientists of the team and national leading talents as the chief scientists of sub-teams, and organized 20 key transformation projects involving the mining and processing of major minerals such as coal, phosphorus, manganese and aluminum, which strongly supported the development of regional industries. The second is to innovate the system and mechanism of school-enterprise cooperation with strategic demand as the traction. We will implement the plan of science and technology commissioners, send 56 doctoral experts to eight industrial fields, such as Maotai-flavor liquor and new energy materials, and 76 small and medium-sized enterprises as vice presidents of industrial technology innovation, build a service model chain of "talent team-leading industries-key production areas-leading enterprises-key scientific and technological projects" for the whole industry, and get through the difficulties of school-enterprise cooperation. Implement the "double tutor+two-stage" postgraduate training mode, encourage postgraduate students to choose key technical problems of enterprises as thesis topics, build a school-enterprise joint talent training mode featuring "ordering", and improve the fit between talent training and social needs. The third is to build a new scientific research organization model with high-quality development as the goal.Implement the cultivation plan of scientific research innovation team, create a new model of "team+",and encourage more than 50 young teachers who have joined in recent years and have strong academic potential to join 14 innovative talent teams such as high-performance polymer materials technology in Guizhou Province, so as to effectively revitalize scientific research resources. Focus on cutting-edge innovative research, create a new model of "discipline+",break down barriers between colleges and disciplines, and set up interdisciplinary research teams such as intelligent perception of crop diseases in mountainous areas of Guizhou Province and scientific and technological innovation talent teams for accurate use of pesticides to promote the integration and innovation of scientific research.

　　Strengthen the construction of talent team.The first is to increase the introduction of high-tech talents. Put forward the working goal of "national talents will achieve a breakthrough of 100 people in 2025", decompose the task of introducing national talents into key disciplines and related secondary units, regularly follow up the promotion of talent introduction in each unit every month, and strive to build a high-level and high-quality scientific research team. In the past two years, 32 national talents and nearly 200 excellent doctors have been introduced. The second is to open a green channel for high-level talents. In view of the fact that some of the leading talents to be introduced are nearly 60 years old, we will actively strive for policy support, and on the basis of strict quality and procedures, we will raise the enrollment age of leading talents who are in good health and have not yet gone through retirement procedures from 60 years old to 63 years old, thus successfully solving the upper age limit of leading talents. The third is to increase the cultivation of key talents. Invite experts from the National Natural Science Foundation to give special guidance and training to academic backbones in the aspects of project application writing and application, so as to enhance their ability to undertake national projects and jointly tackle key problems. Organize mobilization meetings for project declaration, lectures on scientific research integrity, lectures and guidance by well-known experts outside the school and other training activities for young researchers. For newly introduced and trained doctors, we will independently select topics in the field of natural science to carry out innovative basic research and applied basic research, give scientific research funding, and fully support the growth of new academic seedlings.

　　Do a good job in scientific research services.The first is to streamline the scientific research management process. Adhering to the principle of "let information and data run more and teachers run less errands", we will upgrade the school’s scientific research information system, build an integrated information platform integrating data collection and analysis, and realize information resources and data sharing. Optimize project management, examination and approval procedures and reimbursement procedures, continuously streamline work links, and reduce teachers’ transactional burden. The second is to equip with strong scientific research assistants. Each college and scientific research institution is equipped with a scientific research secretary to build a communication bridge between the school’s scientific research department and teachers to ensure that information is conveyed and tasks are implemented in the first time. According to the needs of scientific research work in the college, we employ scientific research assistants to assist the expert research group to promote patent application, data measurement, laboratory instrument management and maintenance, and let experts concentrate on scientific research. The third is to build a strong experimental platform. The Measures for the Administration of Full-time and Double-employed Personnel of the State Key Laboratory of Public Big Data jointly established by the Ministry of Provincial Affairs (for Trial Implementation) was issued, and a leading group for the reorganization of the State Key Laboratory of Public Big Data, headed by the secretary and the principal, was set up to focus on integrating resources and building a strong national laboratory. Regularly update large-scale scientific research instruments and equipment to enhance the accuracy and stability of experimental results and consolidate the basic guarantee for improving scientific research efficiency. In the past three years, 514 million yuan worth of new scientific research equipment has been added, and a high-quality full-time experimental team of 343 people has been equipped.

In recent two years, the domestic IC industry has been paid close attention to by people inside and outside the industry, and the momentum of domestic self-developed chips and domestic self-developed systems in the commercial field is growing. As a technology leader and supplier of domestic self-developed processors, Loongson Zhongke recently brought us a new generation of processor architecture products: Loongson 3A4000 processor.

Godson 3A4000

Introduction of Godson 3A4000

The Loongson 3A4000 processor uses 28nm technology and has four cores, which is consistent with the previous generation 3A3000. In terms of frequency, the Loongson 3A4000 processor is turbo-charged to 2.0GHz, while the 3A3000 processor is 1.5GHz, and the frequency is increased by 0.5GHz. In addition, the Loongson 3A4000 processor is upgraded to GS464V, which supports MIPS64 instruction set, and has expanded more than 1,000 instructions on the basis of only 500 instructions.

On the whole, compared with the previous generation 3A3000, the Loongson 3A4000 processor has not only greatly improved its performance, but also upgraded and optimized its security and encryption, built-in security modules and supported a variety of encryption and decryption algorithms.

Loongson 3A4000 mainframe sample

Because the Loongson 3A4000 processor is a domestic self-developed chip, facing the commercial field, it is not compatible with the mainstream American AMD and Intel platforms in the consumer market, so it needs to use the dedicated motherboard of the Loongson 7A2000 chipset to adapt to it. In addition, the Loongson 3A4000 processor is not compatible with the Windows system based on X86 architecture. The Loongson 3A4000 processor uses the upgraded GS464V architecture, which requires an adaptation system based on LINUX kernel.

This time, the system we used to test the Loongson 3A4000 processor is the UOS unified operating system (UOS is the system code, and this article will use the UOS system uniformly). Based on the LINUX kernel, the UOS system has been adapted to the Loongson 3A4000 processor.

UOS system

Although it is still in the testing stage, UOS system has great potential, which is a safe, easy-to-use and stable operating system product voluntarily initiated and developed by many domestic operating system core enterprises, which is of great significance. Besides Godson Zhongke, other domestic self-developed chip manufacturers will also adapt and support the UOS system, which means that the domestic hardware industry and software industry will be unified and integrated, which will greatly promote the development and progress of the domestic IC industry.

UOS system

At present, except for the newly released 3A4000 processor, some other models of Loongson have been compatible with UOS system, fully adapting to Loongson desktop computers and servers.　

02 Loongson 3A4000 Test

This time, I had the opportunity to get the newly released Loongson 3A4000. We compared it with Loongson 3A3000.

Loongson 3A4000 mainframe

Test platform:

The Loongson 3A4000 processor is a quad-core processor. The basic frequency of this CPU in our test host is 1.8GHz, which can be turbo-charged to 2.0GHz, with a memory of DDR4 2400 8G * 2, a memory of DDR3 128MB and a hard disk of 128G, and its bridge is 7A1000 bridge developed by Loongson.

Godson 3A4000 Host Configuration

Test items:

There are five items in our evaluation this time: WPS three-piece test, image and video opening speed and 7.Zip decompression comparison test, and finally Web page test and SPEC2006 test.

WPS three-piece test:

In the WPS three-piece test, we use more than 10MB documents, more than 20MB tables and more than 300MB PPT to test the opening speed of Loongson 3A4000 and Loongson 33000 processors.

WPS three-piece test

There is no speed difference between the two processors when opening documents with a size of more than 10MB, both of which are within 1 second, but the author can still feel that the Loongson 3A4000 host is smoother and faster with the naked eye. However, the gap between the opening speed of forms above 20MB began to appear. Compared with 3A3000, the Godson 3A4000 improved by more than one second, and the gap in opening speed of PPT above 300MB increased by as much as three seconds. However, in fact, no matter whether using Godson 3A4000 or Godson 33000, daily work can be carried out smoothly without any bottleneck.

Picture Video Open Test:

In addition to office documents, let’s test the video opening speed and picture opening speed of the two processors.

Picture video opening speed

In these three tests, the Loongson 3A4000 processor still occupies an absolute advantage, which is faster than the Loongson 3A3000 processor. At the same time, it also tells us that there is no problem with the view and audio of these two processors, and both the view software, the video software and the OFFICE software linux have products corresponding to the Windows system, such as WPS corresponding to Office, so there is no need to worry about the problem of being unable to use and operate.

7.Zip decompression test:

7.Zip should be familiar to everyone. This is a very popular decompression software, which is often seen in Windows systems. One thing to note is that UOS did not pre-install 7.Zip. We used a notebook equipped with LOONGNIX processor, and the frequency was only 1.5GHz. The Loongnix mainframe was replaced by neokylin system.

After we open the terminal, we input the command LSCPU, and then we can start running after continuously inputting nuame-r and 7z a. The test results of Loongson 3A4000 and Loongson 3A3000 are as follows.

Godson 3A3000 Godson 3A4000 　 　 　

Compared with the 3,709 score of the Godson 3A3000, the running score of the Godson 3A 4000 at 1.5GHz is 5,470, which is about 47% higher, and the score is very impressive. 7.Zip is one of the most commonly used applications in daily life. Although it can’t fully reflect the processor performance, it can show the processor efficiency. Undoubtedly, the efficiency of the Godson 3A 4000 is greatly improved compared with that of the previous generation. If it is the Godson 3A4000 at 2.0GHz,

Principled Technologies WebXPRT 3 test:

Although the UOS system of Loongson 3A4000 platform has not supported much in software testing, the Web page testing is not restricted. The UOS system for web page testing that can be used in Windows system can also be used. We use the Principled Technologies WebXPRT 3 test, which can reflect the performance of all devices that support the Web.

The browser tested is a built-in browser in UOS system, based on the Chromium kernel, which is an open source core and is used by many browsers.

Godson 3A3000 Godson 3A4000 　 　

This Web page tests that it contains six scenes based on HTML5 and JavaScript for mirroring daily tasks. In this test, the Loongson 3A4000 processor still achieved the performance crushing of the previous generation Loongson 3A3000, with a total score difference of 24 points.

In the six scenarios of JavaScript, the efficiency of each operation of Loongson 3A4000 processor has been greatly improved, including photo enhancement by about 63%, photo album arrangement by using artificial intelligence by about 74%, stock option pricing by about 59%, encrypted notes and OCR scanning by about 69%, sales charts by 69% and online work by 49%.

SPEC 2006 test：

SPEC 2006 is a large-scale CPU performance test project, which can fully show the two most important parameters of CPU: fixed-point performance and floating-point performance, and has been recognized by everyone in the field of commercial CPU.

SPEC 2006 test

SPEC 2006 test results

In the test, two processors, the Godson 3A4000 processor and the Godson 3A3000 processor, are compared. These two processors are both four cores. Whether it is the performance test of SPEC INT2006 fixed-point performance test, SPEC FP2006 floating-point performance test and STREAM(GB) memory bandwidth, the performance of the Godson 3A4000 processor has been greatly improved, almost doubling the effect. This performance can be achieved only by optimizing the architecture and increasing the price, which shows that the design and research and development of the Godson are amazing.

03 summary

At present, although the development of domestic chip industry is not as good as that of foreign semiconductor industry, especially foreign semiconductor manufacturers may invest tens of billions of dollars in chip research and development a year, while the domestic chip industry has limited funds, and the chip research and development starts later than foreign counterparts. There is indeed a gap as a whole. However, Loongson has been able to concentrate on research and development for 20 years on one architecture, and continuously iteratively upgrade the Loongson 3A processor chip. It has successively launched the Loongson 3A2000 processor, 3A3000 processor and 3A4000 processor just released at the end of the year, and kept its performance rising, which has fully demonstrated its R&D and design capabilities.

The performance of Godson 3A4000 processor is comparable to that of AMD’s Excavator architecture CPU, whether it is the underlying architecture or the physical design. Moreover, Godson 3A4000 processor can effectively prevent Meltdown and Spectre vulnerabilities, support encryption and decryption algorithms such as MD5, AES and SHA, and eliminate any risks in security.

The Loongson 3A4000 processor adopts 28nm process, and there is still a lot of room for upgrading and optimization. Under the same 28nm process, the CPU performance of the Loongson 3A4000 processor is improved by 6 times compared with that of the first-generation Loongson 3A1000 processor with the same process. It is reported that the next-generation Loongson 3A5000 processor will use 12nm process next year, and the CPU frequency can be increased to 3.0GHz, which is full of stamina.

Ordinary users may have questions, why do you want to launch domestic self-developed CPU chips so vigorously, and it is not good to introduce it abroad? It may be practical in the short term, but it must not be a long-term solution. The core technology is not in our own hands and will inevitably be subject to others. In the field of domestic CPU, what we need to do now is not to catch up blindly, but to avoid being useless, that is, what we need to solve now is the problem of 0 and 1. It is believed that Godson, which has always insisted on independent design and has the ability to realize all independent designs, can enter the civil market in the near future.
