Coping well with insomnia at high altitude

■ Liberation Army Daily reporter Sun Xingwei

　 Jiang chenhui

A soldier Xiao Zhang: I have been stationed in the plateau for some time. After coming to the plateau, I often have insomnia at night, and I can’t sleep over and over again. Even if you fall asleep, you will wake up early. Due to the poor quality of sleep at night, I always feel depressed during daytime training, and my training results are stagnant. With these pressures, it is more difficult for me to sleep at night. This vicious circle makes me very anxious. How to keep a good sleep?

Zhu Zhiru, Military Plateau Medical Research Center: Xiao Zhang’s condition is high altitude insomnia. The hypoxia environment at high altitude can easily lead to the decline of sleep quality. A series of altitude sickness caused by hypoxia, such as headache and dizziness, will also indirectly affect the quality of sleep. In addition, officers and men may suffer from insomnia due to psychological stress, heavy training tasks and irregular life during their training at high altitude.

If the officers and men suffer from insomnia after entering the plateau, they can apply sleep cognitive behavioral therapy to help them improve their sleep. Sleep cognitive behavioral therapy includes five aspects: sleep hygiene education, sleep stimulation control, sleep restriction, cognitive therapy and relaxation training.

Sleep hygiene education. Developing good sleep hygiene habits is conducive to improving sleep quality. I suggest you pay attention to the following points: avoid drinking coffee, strong tea and smoking a lot after dinner; Adhere to regular sports, and exercise for not less than 30 minutes every day; Do not exercise vigorously within 3 hours before going to bed; Don’t eat too much at dinner or fall asleep on an empty stomach; Keep the sleeping environment quiet and comfortable.

Sleep stimulation control. Sleep stimulus control is mainly to establish a positive relationship between bed and sleepiness. Insomnia people can do the following to establish good sleep stimulation control, and then achieve the purpose of improving sleep: do not do things unrelated to sleep in bed; Determine the appropriate time to go to bed and get up according to the actual situation; If you can’t fall asleep after lying in bed for more than 20 minutes, you can get up and do some relaxation activities, and then go to bed when you are sleepy; No matter how late you went to bed the day before, you should get up on time the next morning.

Sleep restriction. The time spent lying in bed is called bed time, and the time to really fall asleep is called sleep time. Sleep restriction is to increase sleep motivation by shortening the waking time in bed. Insomnia people can pay attention to their sleep situation and consciously record the bed rest time and sleep time every night. At the same time, learn to calculate sleep efficiency. Sleep efficiency = sleep time/bed time ×100%. For example, go to bed at 10: 00 at night, get up at 6: 00 in the morning, and stay in bed for 8 hours. If the sleep time is 6 hours, the sleep efficiency is 75%. If the sleep efficiency exceeds 85%, you can increase the bed rest time by 20 minutes; If the sleep efficiency is lower than 80%, reduce the bed rest time by 20 minutes; If the sleep efficiency is between 80% and 85%, the bed rest time will not change. It is recommended to stay in bed for at least 5 hours every day.

Change the unreasonable cognition of sleep. Many insomniacs have unreasonable cognition of sleep, such as thinking that they don’t sleep well if they sleep less than 8 hours a day. Sleep needs vary from person to person, so it is suggested that you try to change the following unreasonable sleep cognition: ① Correct unrealistic sleep expectations, such as expecting to fall asleep immediately after lying down, expecting to get more than 8 hours of high-quality sleep every day, and expecting to sleep until dawn every day. 2 fall asleep naturally, don’t pay too much attention to how long you have slept; Avoid breaking sleep patterns and trying to fall asleep while awake. 3 If there is insomnia, don’t worry too much. Transient insomnia will not cause irreversible damage to the body, and insomnia can be alleviated by scientific methods. ④ Don’t associate work mistakes with poor sleep at night.

Relax training. If you are in a state of mental and physical tension before going to bed, it will lead to insomnia. Comrades can relieve anxiety and tension through relaxation training, thus helping them to fall asleep quickly. Abdominal breathing is a commonly used relaxation training method, which has a certain effect on relieving tension. Consciously carrying out abdominal breathing before going to bed can make people in a calm and relaxed state, thus reducing stress and improving sleep. The operation method of abdominal breathing is as follows: lie on the bed, keep your body relaxed, and then inhale through your nose. When inhaling, feel the breath pass through the nasal cavity, throat, lungs, and reach the abdomen, and let the abdomen expand outward to the maximum extent. After holding your breath for 5 seconds, exhale slowly through your mouth to make your abdomen slowly fall back. Repeat abdominal breathing until you feel safe, calm and relaxed. When doing abdominal breathing, you can also give yourself positive psychological hints, such as "I am calm and I am relaxed".

Under normal circumstances, the quality of sleep will be improved obviously if you insist on cognitive behavioral therapy for 4 ~ 8 weeks. People with long-term insomnia can appropriately extend the time of sleep cognitive behavioral therapy. If you still can’t relieve insomnia after trying sleep cognitive behavioral therapy, it is recommended to consult a professional doctor.

Small coup of self-help sleep

■ Zhang Xi

Sleep is an indispensable physiological demand of the body and an important part of health. Good sleep helps to restore energy, eliminate fatigue and enhance the body’s immunity. In daily life, people may suffer from insomnia, mainly manifested as being unable to sleep, unable to wake up and unable to sleep well. Here, I would like to share some practical methods to relieve insomnia.

Keep a sleep diary. Keeping a sleep diary can help us understand our sleep patterns. Insomnia people can keep a sleep diary for a week or several weeks, including the time of going to bed, the time of falling asleep, the feeling after getting up in the morning, the total sleep time last night, the environmental factors, psychological factors and physiological factors that affect sleep, etc., in order to understand the dynamic changes of sleep state in the near future. By keeping a sleep diary, some people can find out their sleep problems, find out the factors that may affect sleep, and take corresponding improvement measures. Keeping a sleep diary for people with severe insomnia can help doctors understand their sleep more quickly and accurately.

Music therapy. Listening to music helps to relieve tension, thus promoting sleep. Studies have shown that listening to calming music for 45 minutes before going to bed every day for 3 weeks can obviously shorten the sleep time and prolong the sleep time. If you have mild insomnia symptoms, you can listen to some music with slow and steady rhythm before going to bed, such as Qin Qu "Running Water" and "Moonlit Night on a Spring River".

Hot foot bath or hot bath. Soaking feet with hot water before going to bed can dilate the capillaries of feet and increase the blood flow of limbs, thus playing the role of calming the nerves and helping sleep. When soaking feet with hot water, it is best to choose a deeper bucket, and the amount of water should be soaked to more than half of the calf. The water temperature should not be overheated, and it is recommended to be around 40 degrees Celsius. Don’t soak your feet for too long. Generally, it is recommended to soak your feet for 15 ~ 30 minutes. Hot water bath can dilate the blood vessels in the whole body and reduce the blood flow of internal organs. As the blood flow to the brain decreases, the brain will feel tired, thus promoting sleep.

Auricular point pressing. Modern medicine believes that insomnia is caused by the imbalance between excitement and inhibition in the cerebral cortex. There are abundant nerves around the ear. Pressing and stimulating the points in the ear can adjust the excitement and inhibition of the central nervous system and help improve the quality of sleep. The main operation steps of auricular point pressing are as follows: Select the pillow point and the point before hanging, take a disposable auricular point paste, and apply some pressure to it, which is suitable for local fever and swelling. It is generally recommended to press auricular points before going to bed. Pay attention to the following items when pressing: avoid sticking ear points to be wet to prevent skin infection; The sticking time in summer should not be too long, and it is recommended not to exceed 3 days; It is not suitable to apply when there is chilblain and inflammation in the ear; If you feel pain at the sticking point when lying on your side, you can take off the ear acupoint sticking; Don’t rub your ears when pressing, so as not to rub your skin and cause ear point infection.

　　Nanning, China, July 27 (Jiang Xuelin, Luo Xianbin) According to the information provided by the Environmental Protection Department of Guangxi Zhuang Autonomous Region, after the central environmental protection inspector group moved in, Guangxi set off an environmental storm, and four cadres in Yulin City, Guangxi Province were held accountable for failing to perform their duties seriously. A leading grain processing enterprise in Nanning was suspended for rectification due to odor pollution to surrounding residents.

　　According to the information provided by Guangxi Environmental Protection Department, on July 23, the Central Environmental Protection Inspector Group transferred a petition case of environmental pollution from Santong Farm in Luchuan County, Yulin City. Yulin City and Luchuan County attached great importance to it, and the Luchuan County Government immediately formed a working group to investigate and deal with the unauthorized expansion of the farm. Luchuan County Supervision Bureau quickly launched the accountability mechanism, and held four responsible persons with supervisory responsibilities accountable.

　　After investigation, the four responsible persons did not seriously perform their duties to inspect and verify the construction scale of Santong Farm, which caused the farm to expand the pigsty area and breeding scale without authorization, and the air pollution caused by a large amount of discharged wastewater affected the lives of surrounding villagers. In this regard, the Luchuan County Supervision Bureau filed a case against Luo Yuyu, the head of the county environmental monitoring brigade with the main leadership responsibility, and Zhong Yingyue, the captain of the breeding squadron of the directly responsible monitoring brigade, and gave administrative warnings; Cai Junyong, the chief of the Animal Husbandry and Feed Unit of the County Animal Husbandry and Fisheries Bureau, and Huang Qiuping, the deputy mayor in charge of the ancient town government of Luchuan County, were admonished.

　　In Nanning, the presence of the Central Environmental Protection Inspector Group has also given people around the city’s economic development zone an opportunity to solve the problem of pollution. Nanning Liyuan Grain, Oil and Feed Co., Ltd., located in the Economic Development Zone, has an annual output of more than 700,000 tons of feed, and its market share in Guangxi feed is about 30%. It is a leading enterprise in Nanning. It is also a big tax collector in economic development zones. However, since 2015, the company has become a major complaint by the public. This enterprise uses raw materials that are easy to produce odor (odor) such as palm kernel cake for feed processing, which is easy to produce odor during storage; In addition, in the production process, the processes of adding, mixing and crushing raw materials will emit foul odor, which is often complained by the surrounding residents. The secretary of the Nanning Municipal Party Committee and the mayor have given instructions on the complaints, but the problem has not been solved.

　　On July 14th, after the Central Environmental Protection Inspector Group settled in, the problem was reflected to the Inspector Group. On the 21st, Nanning exposed the enterprise. On the 25th, Nanning Environmental Protection Bureau issued a notice of suspension of production and rectification to the enterprise. On the 27th, when the reporter entered the enterprise with the staff of the local environmental monitoring detachment to check the rectification situation, he saw that the enterprise had stopped production, the bad smell was no longer so obvious, and the workers were adding closed baffles to the raw material warehouse.

　　Chen Chunqi, the captain of the Economic Development Zone Brigade of Nanning Environmental Monitoring Detachment, said in an interview with Zhongxin.com that the presence of the inspector group provided an opportunity to solve the pollution problem of the enterprise. The enterprise was built in Economic Development Zone in 2003. At that time, its location was relatively remote, and the odor produced by the enterprise was not obvious to the residents. In recent years, with the development of the city, Nanning Economic Development Zone has been surrounded by residential areas, and the enterprise will move sooner or later, and the Economic Development Zone is also planning the factory land for the enterprise.

　　Tang Jinsheng, general manager of Nanning Liyuan Cereals, Oils and Feeds Co., Ltd. said that in order to solve the odor problem in the production process of the enterprise, the enterprise will invest 1 million yuan to rectify the production line in the factory. Stop using palm kernel cake and other raw materials that are easy to produce malodor (odor), and cancel the grinding process that is easy to produce odor.

　　It is reported that as of July 21, among the 213 environmental reporting problems assigned by the Central Environmental Protection Inspector Group, Nanning has assigned the most cases, reaching 52, and 24 have been reported. In response to a case reported by the masses that a chemical fertilizer plant in Guigang privately set up concealed pipes and discharged wastewater beyond the standard, Huang Xingrong, deputy mayor of Guigang City, made an on-site inspection and convened a joint meeting of the Municipal Public Security Bureau, the Municipal Environmental Protection Bureau, the Gangnan District Government and relevant departments to study and deploy the case investigation work.

　　Yangzi Evening News (correspondent Zhu Tianxuan, reporter Chen Yong) The newly graduated college students rented a house through a real estate agent, and as a result, they paid the agency fee of 400 yuan, and waited for one month without seeing the house. After receiving the call for help, Nanjing Xuanwu police intervened in the investigation and found that the young man was "routine" by the real estate agent.

　　One day in early September, the police service station of Meiyuan New Village of Nanjing Xuanwu Public Security Bureau received an alarm from Xiao Wang, a young man, saying that he had encountered a dispute when renting a house, and the house had not been rented, and the agency fee paid by 400 yuan would not be returned. After receiving the alarm, the policeman Wu Chao got in touch with Xiao Wang.

　　Xiao Wang told the police that he just graduated from college this year. A month ago, he saw on the Internet that this intermediary had a room with a desirable price, location and decoration. "From the photos, the room is very bright and tidy. If this location can really rent such a room at this price, it is really lucky." Xiao Wang said that he immediately contacted an intermediary who claimed to be surnamed Zhang and met to see the house.

　　According to Zhang’s instructions, Xiao Wang came to the real estate agency office located in an office building on Zhujiang Road. Zhang warmly received Xiao Wang, saying that he had confirmed that the room was still there, but he had to charge 600 yuan’s agency fee before going to the house. Xiao Wang Gang graduated, and was short of money. After some bargaining, the two sides finally made a deal with the 400 yuan agency fee. Then the intermediary gave the contact information of Xiao Wang’s landlord, and specifically told him: "The landlord is busy at work and will call again after 6 pm." After 6 o’clock in the evening, Xiao Wang telephoned the landlord to make an appointment to meet downstairs in the rented house the next day.

　　However, when Xiao Wang arrived at the appointed place the next day, the landlord didn’t show up. "I called the landlord, but the landlord said that he had an urgent business trip, and it would take half a month to return to Nanjing. I was anxious to rent a house, so I called the intermediary again. The intermediary said that he would help me find a more suitable house and promised until I took a fancy to it, but I didn’t take the initiative to contact me after that." Xiao Wang told the police that he had been to the intermediary office several times in the past month, but it was strange that the door was often closed and no one could be found there.

　　After understanding the situation, the police took Xiao Wang to the office of the intermediary involved, which happened to be open that day. Xiao Wang said that he had found other suitable houses and asked the intermediary to return the agency fee. Under the mediation of the police, the intermediary finally refunded the intermediary fee to Xiao Wang 400 yuan.

　　"In fact, we have recently received a lot of similar rental disputes." The police told reporters that many people had similar experiences with Xiao Wang. In fact, they were all given "routines" by intermediaries. "In addition to the alarm that we can’t see the house, we have received other similar alarms. For example, the houses that are optimistic on the Internet are very different from the actual ones. For example, the 500 yuan/monthly rent that was discussed at the beginning immediately became 1,500 yuan/month after seeing the actual room." In these situations, basically, the renter paid the agency fee first. Moreover, the intermediary is also very cunning. In order to avoid the renter from recovering the intermediary fee, they often change their office locations.

　　Because the agency fee is not high, many people really can’t afford it, so they will give up the agency and find another house, and the agency fee is not required. Not many people really come to the police for help.

　　Cctv newsAccording to the website of China Banking and Insurance Regulatory Commission, China Banking and Insurance Regulatory Commission recently issued the Measures for the Supervision of Accident Insurance Business. The Measures focus on the outstanding problems such as low payout ratio, abnormally high commission and irregular sales behavior, dig deep into the root causes, conduct targeted governance from the system, and comprehensively standardize the development of accident insurance business, covering product actuarial, terms and rates, sales management and information disclosure.

　　The main contents are as follows:

　　The first is to improve the formation mechanism of rate marketization. Establish a retrospective and rate adjustment mechanism for accident insurance products, link product rates with payout ratio and other indicators, and gradually eliminate products with low payout ratio and obviously unreasonable pricing.

　　The second is to strengthen information disclosure. In accordance with the principles of individual insurance first, group insurance first, pilot first and comprehensive, we will disclose accident insurance business data, cooperative institutions, payout ratio and typical cases step by step, and gradually expand the scope of insurance coverage.

　　The third is to guide and reduce the level of commission fees for accident insurance. All insurance companies are required to report the upper limit of commission rate, and guide insurance companies to pay commission fees reasonably to better benefit consumers.

　　The fourth is to make a negative list of sales behaviors. Based on the irregular problems in the accident insurance market, nine types of prohibited behaviors are listed, including bundling and compulsory tying.

　　The Measures will help to further improve the market-oriented formation mechanism of accident insurance rates, standardize the accident insurance market order and promote the long-term healthy development of the accident insurance market. In the next step, China Banking and Insurance Regulatory Commission will do a good job in the implementation of the Measures, simultaneously promote the standardization of accident insurance and establish an anti-insurance fraud mechanism, deepen the reform of accident insurance and better protect consumers’ rights and interests.

　　[PConline cross review]2019 is coming to an end. For the majority of DIYer, the first half of 19 years belongs to Intel；; In the second half of 19 years, it belonged to AMD.

In the first half of 2019:

　　Intel can still stably suppress AMD’s market share in the first half of the year only by relying on the toothpaste left by Skylake. It can be said that in the DIY market in the first half of the year, Intel still didn’t take AMD as an opponent.One thing said, Intel is really good at playing games.

In the second half of 2019:

　　The first two generations of Ruilong made AMD’s CPU department slightly better. In July, the three generations of Ruilong were AMD’s challenge to Intel:Don’t treat us like ants, the times have changed since today!

　　On the day of summing up at the end of this year, I will send you the annual popular A/I CPU cross-evaluation, which will be used as PConline’s 2019 CPU ranking.

　　This time, only the popular processors were selected as the horizontal selection. If you want to see a more complete ranking, you can click here to enter the 2019 CPU ladder diagram.

Six popular CPUs on e-commerce platform

　　This review is not in ceiling price. In recent years, in addition to the students who installed machines for cost performance, they also installed machines for the pursuit of ultimate performance. Therefore, the sales of high-end CPU are relatively high this year, which is of reference value for adding statistics. However, when the total score is evaluated horizontally, the price will still be added to the scoring item.

　　Based on the sales statistics of multi-e-commerce platforms, we selected six CPU models that sell well every year:

I. Intel i5-9600KF/　i5-9400F

　　“The middle-end main force that takes advantage of the right time and the right place."

　　The first place in sales volume is often occupied by Core i5, but this year’s Ruilong 3600X is also very competitive. In addition, the ninth generation Core i5 came out much earlier than the 3600X, and the accumulated sales volume is more reasonable than the latter.

　　Both CPUs are i5 of the ninth generation, and the sales volume is relatively hot. Here, I choose i5-9600KF as the representative of Intel.

Second, AMD Ryzen 5 3600X

　　"Sales champion in the second half of 2019"

　　During the period when the third-generation Ruilong CPU was just launched, apart from the eye-catching Ryzen 9 3900X and Ryzen 7 3700X, what attracted people more was the Ryzen 5 3600X with 6 cores and 12 threads. Everyone could count the boxes.

Iii. Intel i7-9700K

　　"The most cost-effective game artifact in the high end"

　　If you want to play games, you have to look at Intel. Compared with the situation that game optimization stopped at 4 cores a few years ago, the game’s support for 8-core CPU is not good now, but at least it has been done. Some large 3A masterpieces can really enjoy the performance bonus brought by multi-core, and Intel’s high-frequency and high-energy characteristics are very suitable for game scenes. Cutting the hyper-threading function that has zero effect on games, the i7-9700K is indeed the most cost-effective high-end CPU suitable for playing games this year.

Iv. AMD Ryzen 7 3800X/Ryzen 7 3700X

　　"showstopper that impacts the high-end CPU market"

　　It is also two high-end CPUs that big game players pay attention to, both of which are 8-core and 16-thread specifications. Ryzen 7 3800X can be regarded as a better Ryzen 7 3700X.

　　Although the game is not as good as i7-9700K and i9-9900K, the performance-price ratio and comprehensive performance are weighed together, and they are more worthy of purchase than two Intel high-end CPUs. Here, Ryzen 7 3800X, which is slightly stronger, is selected for comparative test.

V. AMD Ryzen 9 3900X

　　"miracle of 7nm, I/O die and glue MCM packaging"

　　In fact, in terms of miracles, its eldest brother Ryzen 9 3950X is more suitable, but because Ryzen 9 3950X keeps jumping tickets and has been in a "snap-up — — "Out of stock" status, as of the time of our statistics, we have not accumulated much sales, so we can’t be on the list.

　　The CPU of AM4 interface can be packed into 12 cores or even 16 cores, which is closely related to AMD’s newly designed core architecture. CCD+I/O die is more flexible than the big core route that Intel has always adhered to.

VI. Intel i9-9900KF

　　"Can it be used without exceeding 5GHz?"

　　Perhaps because i9-9900K is the flagship CPU launched at the end of 2018, itI lost to the low nuclear display version i9-9900KF.

　　After thinking about it, the value of this CPU should be that it will exceed 5GHz immediately after being bought back, and then it will be used to brush bilibili and visit Weibo, at least in the view of supercontinent. (Manual dog head)

▼Comparison of six CPU specifications: AMD is confident.

　　The CPU parameters are listed here. On the whole, the CPU specifications of AMD seem to be more bright: 7nm+ multi-core+super large three-buffer +PCIe 4.0, and the frequency span between different CPUs is not large. Intel dominates the high-frequency direction, and the frequency span between the mid-range and high-end CPU is large.

Test platform construction

　　Let’s introduce our evaluation platform first.

　　The hardware of the evaluation has been used all the time. The first thing to ensure is that the platform is stable and reliable.

　　As for the motherboard, both Z390 chipset and X570 chipset use ROG HERO series, with the same positioning, which reduces the performance impact caused by different motherboard specifications.

　　The radiator is GI-CX360 water-cooled with overclocking triple mirror. Because the specification span of CPU in this test is large, it will be safer to use 360 water-cooled.

　　The memory is pulled out from four Kiki royal halberds, and the combination of double 8GB is enough to give full play to their performance.

performance test

Theoretical performance test▼

　　The theoretical performance test project will test a variety of traditional running software, and whoever scores high will be powerful, simple and rude.

▍　CPU-Z v1.90

　　CPU-Z test items are divided into single-thread and multi-thread. It can be seen that i7-9700K and i9-9900KF with higher frequency have completely outperformed AMD’s three participating CPUs in single-thread performance, which should be a predictable result without testing.

　　In terms of multithreading performance, Ryzen 9 3900X has no suspense, and the 12-core 24-thread specification crushes the other five participating CPUs. Being both 8-core and 16-thread, Ryzen 7 3800X multi-threaded performance is higher than i9-9900KF with stronger single-core performance.

　　Ryzen 5 3600X with 6 cores and 12 threads is basically the same as i7-9700K with 8 cores and 8 threads, so i5-9600KF can only be a younger brother among them.

▍　CineBench R15

▍　CineBench R20

　　CineBench is a running score software that scores by testing the rendering speed. No matter whether this pile of CPU is in R15 or R20, the multi-thread performance ranking is the same. The multi-threaded performance of Ryzen 9 3900X still surpasses the other five CPUs, and in R20, the single-threaded performance of AMD processor actually surpasses the high-frequency i9-9900KF.

▍　wPrime 2.10 1024M

　　WPrime is a software that tests the computing power of CPU by calculating prime numbers, and it is also very direct and violent. The multi-core Ryzen 9 3900X is still popular, and the testing time is nearly half that of i9-9900KF. The slowest is i5-9600KF, because the number of core threads is relatively small, and Ryzen 5 3600X, which is located close to it, is much faster than it, only 60% of the time.

3DMark Time Spy Extreme physical score▼

　　3DMark’s TSE project is also a software with multi-threading performance. Ryzen 9 3900X is still in the lead, while i9-9900KF with stronger high-frequency single-core performance is about 400 points away from Ryzen 7 3800X of the same specification.

Compressed file performance test▼

　　Compression software is often used by people. Because the compression software algorithms are different, the speed of compressing files among different compression softwares will be different. Here, two compression softwares are selected for testing: WinRAR, which is used by many people, and 7Zip, which comes with Benchmark.

▍　7-Zip benchmark score

　　In the 7-Zip test, the distance between AMD processor and Intel processor is very large. The score of Ryzen 7 3800X is 11.3% higher than that of i9-9900KF with the same core specification, and Ryzen 9 3900X continues to lead.

▍　WinRAR compressed file speed

　　WinRAR, the result here is reversed. Ryzen 9 3900X is 4.3% slower than i9-9900KF, and i5-9600KF is still stable at the bottom. Let’s click on the big picture to compare the other figures.

Performance test of office scenario simulation application▼

　　Most of the test items of PCMark are aimed at daily office applications, such as web browsing and document editing. Ryzen 9 3900X still doesn’t have much advantage, only 1.8% higher than i9-9900KF, which shows that CPU with high frequency and strong single core will be better used in this kind of project.

Professional software application performance test▼

　　Compared with the daily office work above, professional applications will test the performance of CPU more, among which multi-threaded applications are the majority. In theory, Ryzen 9 3900X with more cores will have more advantages.

▍　POV-Ray Benchmark

　　POV-Ray Benchmark is a software for testing the rendering performance of CPU. It can achieve results by rendering a large picture and calculating the average rendering pixels per second.

　　Ryzen 9 3900X outshines others, i9-9900KF is similar to AMD 3800X, while i5-9600KF, which has lost the number of threads, has fallen into the sewer and can’t get out.

▍　FHD X264 Benchmark

　　FHD X264 Benchmark tests and records the rendered frames by exporting the video. Ryzen 9 3900X here is not much different from i9-9900KF, only 6.4%.

▍　ArcTime Pro video compression and export

　　ArcTime Pro is the normal process of exporting video. Here, the performance of Ryzen 9 3900X with more cores is relatively normal, and the distance between i9-9900KF is a little bit.

　　This shows that if you do video work, it will be more popular with more cores/threads. Ryzen 9 3900X has the best performance in these products and is more suitable for video workers. The performance of i9-9900KF is also good. Although the number of cores suffers, the actual performance gap is not as big as the proportion of core numbers.

　　Summary of theoretical performance test:There’s nothing to say about small projects. The core specifications and performance of the processor are here. We can know what’s going on by comparing them. What Supercontinental wants to talk about here is the problem that AMD’s multi-thread performance surpasses Intel’s when its single-thread performance is slightly weak.

　　To put it simply, the SMT technology of Ryzen CPU is a little more powerful than the HT technology of Core I series, and the multi-core utilization rate is higher, which is why the single-thread performance of Ryzen 7 3800X is not as good as that of i9-9900KF in many of the above projects, but the multi-thread performance is reversed.

　　"Multi-frame" is bound to be the trend of future development.Win10 system is a good example. You won’t see the scene of Win7 "one core is in trouble, and N cores are watching" in Win10 system. AMD has made a better decision than Intel on how to optimize the performance of "multi-frame".

Game performance test

　　The number of game masterpieces this year is also dizzying, and the two processor manufacturers are also keen to use game performance as their selling point.

　　Here, six popular online games and 3A masterpieces are selected for testing, and the image quality is uniformly set to 1080P resolution, with the lowest image quality. The reason for this setting is to reduce the influence of graphics card bottleneck and maximize the performance difference of CPU.

▍　Tomb Raider: Shadow

▍　DOTA2

▍　GTA5

▍　Total War: Three Kingdoms

▍　Assassin’s Creed: Odyssey.

▍　Jedi survival: the great escape

　　Game test summary:All six CPUs can make the game run at more than 100 frames, but in Tomb Raider: Shadow, Total War: The Three Kingdoms and The Great Escape of the Jedi, the performance of Intel’s two high-end CPU games has obviously abandoned the rest of the processors.Take the position of the first brother of Intel Games..

　　The "extreme game performance" that Intel has been boasting is indeed well founded.However, the game running at such a high number of frames, except for some e-sports big brothers who use 240Hz screens, can actually ignore this frame gap to some extent.

　　Moreover, our test is based on the setting of 1080P resolution and the lowest image quality. If the image quality is properly raised, the graphics card and CPU will tend to be performance bottlenecks, then the gap between them will be narrowed.

Temperature and power consumption test

　　Because it is impossible to test the power consumption of a single hardware, there have been data errors when the software reads the hardware power consumption information. Here, Nortel instrument power consumption meter is used to test the power consumption of the whole platform, and Tomb Raider Benchmark is used to test the full load of the game.

　　I9-9900KF showed the phenomenon of frequency reduction during the test, and the power consumption was lower when the game was fully loaded and tested by Prime 95 than that of i7-9700K. Combined with the above Tomb Raider game test, the frame number of i9-9900KF in the game was not as good as that of i7-9700K, which can explain this phenomenon.

　　On AMD’s side, the power consumption of three generations of Ryzen processor can be effectively controlled by the 7nm process. The power consumption of Ryzen 9 3900X single baked FPU is only 278W, which is nearly 30W lower than that of i7-9700K, which has the highest power consumption. The former is a "miracle species" with four more cores than the latter.

　　As a result of opening PBO, three generations of Ryzen processor hit a temperature wall of 95°C together when baking FPU to reduce the frequency.

　　Intel processors have much lower power consumption and lower frequency at low frequency. The baked FPU of i5-9600KF with few cores is only 68°C, while the 8-core i7-9700K and i9-9900KF have reached the 90°C mark due to more cores and higher frequency, but the temperature is still lower than that of AMD processors.

Summary of PConline evaluation room

▼Comparison of comprehensive performance of six popular CPUs：

　　Hard to do the test, and finally for this comprehensive comparison table, which is the essence of the whole test.

　　The comprehensive performance gap table is the data obtained by synthesizing all the above test items except temperature and power consumption. Because many items will eat multithreading performance, Ryzen 9 3900X undoubtedly won the comprehensive performance championship.

　　Look at the other contestants, i9-9900KF and Ryzen 7 3800X with the same specifications. Although the latter is blessed by SMT technology, some multithreaded scenes will perform slightly better than the former.However, the game is the strong point of i9-9900KF, which lags far behind Ryzen 7 3800X, and wins by high-frequency performance..

　　Because i7-9700K has no hyper-threading function, even if the game is strong, the multi-threading scene drops too many points, and its comprehensive performance is even worse than that of Ryzen 7 3800X, and even it is almost caught up by Ryzen 5 3600X with fewer cores.

　　There is nothing to say about the i5-9600KF. Except for games, other projects are basically at the bottom, but U is actually a good U, but it just happens to be the cheapest and lowest specification one in this horizontal review.

　　Comparing Intel’s game strengths, there is no suspense, but in fact AMD is not too far behind Intel, which is worthy of surprise.

　　Because our game tests are all set to the lowest quality special effects to enlarge the game performance gap between CPUs, the gap will be even smaller if the high quality special effects are turned on.

　　Cost-effectiveness is also a concern for everyone to buy a processor, but there is no more scientific measurement method, so here is a simple and rude one.CPU price ÷ comprehensive performance percentage, get the unit price per percentage of performance. As a result of this calculation,Ruilong 3600X has the highest cost performance and i5-9600KF has the second highest cost performance..

　　Anyway, the smaller the number, the higher the cost performance.Overall, AMD Ruilong will be slightly more cost-effective than Intel Core..

　　As for the unscientific comparison method, I can tell you responsibly: it is good for everyone to have fun, and everyone has his own scale in his heart.

　　Because the higher the performance, the more difficult it is to improve the performance, so how to calculate here will be that the middle/low-end processors have higher cost performance: because the cost of realizing their performance is very low. High-end processors are expensive, and it takes hundreds or thousands of RMB to improve the performance of 10%. Whether it is worth it or not is a matter of opinion.

▼Summary time for expressing personal opinions — —

　　At the end of 2019, Supercontinental believes that it is meaningless to discuss the issue of "whether the processor performance is excessive".

　　As for the reasons, I don’t need to be embarrassed. Everyone is from the era of the media.The demand for creative CPU has soared., playing games to buy less core high-frequency CPU. For those creators and big UP owners, their demand for CPU performance can be said to be bottomless.

　　Therefore, regardless of the use requirements, all those who say that the CPU performance is excessive should be treated as hooligans.

　　Undeniably, in this year’s CPU market, Intel is still firmly on the throne of the game boss.I also changed my computer for playing games to i7-9700K.In some games with high demand for the stability of game frames, it is indeed better than AMD. (It’s not that I’m black, sometimes I really get stuck playing games with AMD processors.)

Sometimes I just get stuck suddenly and then I get disconnected.

　　On the comprehensive ability, AMD with "excess performance" will be even more brilliant.,In other words, AMD’s processors have become "all-powerful"Ryzen 9 3950X, which has the largest number of consumer platforms, has a higher acceleration frequency than any other Ryzen processor. What’s the concept? Not only do you have multi-core advantages at work, but you can also enjoy high-frequency advantages when playing games.

　　Coupled with the rest of AMD’s product lines, the "ceiling" EPYC Rome CPU with servers, and the weakness is the thread ripper of the fever platform. APU more suitable for the low-end platform will also come, and everyone can find their own heart water products in AMD.

　　This year is the flowering and fruiting period of AMD Ruilong.

　　It’s always good to have competition. AMD’s ZEN architecture has given people renewed confidence in Moore’s Law. In order to continue to consolidate its own market, Intel will also speed up the pace of new products, and ultimately, users will benefit. This year’s new CPU products are worthy of our happiness.

▼Guide for purchasing 6 processors (recommended) — —

▍　I5-9600KF 1399 yuan

　　Like i5-9400F, it is stillThis year, there is a high purchase value of CPU.In office, online games and most 3A masterpieces, it will have better performance, and the owner of Internet cafes should like this CPU better.

　　If the game you play is biased towards Tencent online games and the budget is not much, it will be a better choice.

▍　Ryzen 5 3600X 1499 yuan

　　Compared with the above two i5s, this processor has no price advantage.But the comprehensive performance will be stronger.. With the SMT hyper-threading function, I think it is more suitable for users who usually work and play games moderately, and they can also play games by editing pictures and repairing drawings. Professional performance is better than i5, and the game loses a little bit, but it’s not too bad.

▍　I7-9700K 2899 yuan

　　Subjective opinion:If you want me to recommend the CPU in 2019, I think this is the most fragrant CPU. After exceeding 5GHz, the game performance is off the charts, and it has experienced the latest wave of price reduction, which is very affordable.

　　Objective opinion:The 8-core specification is just right for most games, but it doesn’t have hyper-threading. It may not be as good as AMD’s Ryzen 7 series when dealing with work. It belongs to a processor made for games. After the price reduction, the price/performance ratio is really high. It is recommended for game enthusiasts with little budget.

▍　I9-9900kf3,499 yuan

　　The strongest game processor ordered by Intel, but there is also an i9-9900KS in this series, which is the complete body of the 9900K series.

　　Compared with i7-9700K, it has more hyper-threading function, and it has good performance in both games and work. Personally, it is suitable for game anchors — — Turn off Hyper-Threading when playing the game live, turn on Hyper-Threading when editing the essence live, and release the film quickly.

▍　Ryzen 7 3800X 2599 yuan

　　Ruilong 7Their positioning is equivalent to i9-9900K, but the game is obviously not as good as the latter.

　　Because they all have hyper-threading function, their comprehensive performance is stronger than Intel’s, and they are more suitable for working machines. It is recommended that users with low budget should buy them with good working performance and strong game performance.

▍　Ryzen 9 3900X 3999 yuan

　　4,000 yuan, I don’t think I’ll even know if I don’t have a mine at home.

　　The game is still inferior to Intel.But the comprehensive performance is the strongest here.,Those who pursue extreme productivity can consider it.,Or even more extreme, its eldest brother Ryzen 9 3950X.If you have a gold mine at home, you can also choose a higher-end thread ripper series.

　　That’s the end of this article. It’s not easy to test+code words, more than 5,000 words. If you approve PConline evaluation, please give us a coin-operated attention.

Original chestnuts guoke

People with normal vision read by light. The white paper is brighter and the black words are darker, so the naked eye can distinguish the words between light and dark.

What does the visually impaired read? One is by touch, and there are blind documents to touch. One is hearing. When some books are not translated into Braille, maybe you can find audio books.

If you can’t find a ready-made audio book, how can the blind read an ordinary printed book?

As early as 1913, Edmund Fournier d’Albe, a physicist at the University of Birmingham in the United Kingdom, showed a scanner to help the blind listen to books, named "Optophone" (photoelectric reading device). A few years later, the equipment was transformed into a more practical version by a scientific instrument manufacturer.

In 1920, the magazine reported Scientific American.

When the machine sweeps a line of words from left to right, there will be a sound in the user’s headphones. However, the sound is not speech, but a combination of some notes.

Write the word "write" with notes.

Different note combinations represent different glyphs. For example, the letter T has a horizontal direction and a vertical direction, the horizontal direction is represented by a monosyllabic elongation, and the vertical direction is represented by a chord. The notes used here are the highest to SOH and the lowest to the lowest octave SOH.

The note corresponding to the letter t, Tiffany Chan

The height of the notes reflects the position of the ink on the paper: one horizontal of the T is at the top, just lengthen the highest note SOH, while one vertical of the T has ink from top to bottom, so you can play the five notes of SOH, FAH, MI, ME and DOH at the same time, which is a chord.

Then, when the letter T appears, the earphone should first emit a continuous SOH, with a short chord in the middle, and finally return to the continuous SOH. A letter, a word or a paragraph can be "written" with a string of notes:

The note combination corresponding to the word "Type" is Tiffany Chan.

As long as you are familiar with the correspondence between letters and note strings in advance, the blind can hear the contents of a book.

Translating glyphs into notes is not complicated in terms of rules, but it is only part of the work of this machine. Before that, it must first see what font is printed on the book before it can begin to translate.

Therefore, automatically scanning text is the most important thing.

Selenium can see black and white.

At the beginning, the naked eye can distinguish the words on the paper by light. The light returning from black letters is very weak, not as strong as the reflection of white paper. But how does the machine achieve similar perception?

Scientists thought of selenium, and the resistance of this substance will change with the intensity of light. Connect batteries on both sides of selenium. When the light hits the ink mark and then reflects to the surface of selenium, the resistance of selenium will be larger, and the current passing through it will be smaller. When light is reflected from the blank of the paper to the surface of selenium, the resistance of selenium will be smaller, and the current passing through it will be stronger.

The two sides of selenium are connected with a power supply, and the current is different with or without lighting [1]

Different lighting conditions will transform different electrical signals, so selenium can be used as a photodetector. When it sweeps a line of words from left to right, the signal strength will change with the alternation of black and white, which is not difficult to understand. The question is, how does the machine know whether the ink position is high or low, such as whether T is above or below?

Use different beams to scan different positions. If you divide a line of words into five layers, you need five different beams of light to scan it. The so-called different light means that each beam of light hits the surface of selenium to produce a unique electrical signal, which is different from other beams of light. Only in this way can we tell how high the light is calling from.

Divide a line of words into five layers [1]

So how do you divide a beam of light into five different beams?

Here is a porous disk with five holes. When the disc rotates at a speed of 30 revolutions per second, a beam of light is knocked over, and the light passing through the disc is divided into five beams, which are five intermittent (or fast flashing) lights.

Porous disc, Wikimedia Commons, reference [1]

When light is reflected to the surface of selenium intermittently, the current passing through selenium will fluctuate. The current fluctuation caused by these five beams of light is different: because the number of holes in five circles is different, the more holes, the more frequently the light is cut off and the higher the frequency of current fluctuation.

So there were five different beams of light. If they are hit at different positions, we can judge whether the light is reflected from a high place or a low place according to the frequency of current fluctuation. It’s not difficult to tell the difference between a horizontal T and a horizontal T.

The disc divides the light into five different beams.

The notes that users hear are also distributed according to the frequency of current fluctuation.

As for what tools to use to sense the fluctuation of current, the sensor in the telephone receiver can be competent. With the technology at that time, current fluctuations as small as 10-6 amps can be detected.

Is it black or white?

Wit, you may find that according to the principle described above, the strong current signal is the blank, and the weak signal is the ink mark. So, the notes that users hear represent not the ink, but the gaps around the ink?

This was the case with the original products in 1913, and those notes that the user did not hear indicated the location of the ink. When the spaces between words are scanned, all the notes will play together. Therefore, the inventor called it "White-Sounding Optophone".

The combination of notes it plays is so complicated that Mary Jameson, the best user, is trained to read only one word a minute on average. But she still became the first blind person to read ordinary printed books.

In 1918, Barr & Stroud, a manufacturer of scientific instruments, improved the equipment and added a second photosensitive element made of selenium to the photoelectric detector. After the light passes through the disc, part of the light still scans the text and reflects to the first photosensitive element; The other part of the light is directly turned to the second photosensitive element without scanning the text.

Add one more photosensitive element. Popular Science

By combining the signals of the two photosensitive elements, the signal of the blank part can be cancelled. In this way, the notes played by headphones represent ink and letter shapes, while the blank parts are muted. This version is also called "Black-Sounding Optophone".

Of course, its advantage is not only that the combination of notes becomes simple. The structure of the original equipment is fragile. Even if someone walks by heavily, some components may slide to the wrong position, which will affect the normal scanning. The improved equipment is much more stable.

In addition, the improved version also adds the function of adjusting the scanning speed, which can scan a line at the fastest time of 5 seconds and at the slowest time of 5 minutes. Users can choose the speed according to their proficiency in recognizing notes.

Mary jameson is reading Walden Lake.

Mary jameson also used an improved version of this "black voice". Later, her reading speed reached 60 words per minute. Mary became a heavy user of photoelectric reading devices from her school days to her later years.

But for most people, the combination of notes may still sound too complicated. Moreover, some letters with similar shapes, such as "u" and "n", are easily confused. In addition to using the threshold, the price is also prohibitive. 35 pounds in 1920 is about 1,500 pounds (about 13,000 RMB) or more today.

In 1920, the average price of a house in London was about 320 pounds.

In addition, the British Association for the Blind was trying to popularize Braille resources to the whole country, and the photoelectric reading device may pose a threat to the promotion of Braille, and it will not be supported by the association, and the sales volume has been pitiful.

However, commercial failure does not necessarily mean technical failure.

Technology that anyone may need.

In 1949, the engineers of RCA borrowed the principle of photoelectric reading device to create a new reading machine for the blind.

RCA reading machine, which can play the pronunciation of letters, such as "A-"[5]

It also needs to strike the light on the paper and then reflect it on the photoelectric element, thus distinguishing the shapes of letters; It also has a horn, which is responsible for shouting the corresponding sound.

However, the light-emitting device is no longer a lamp with a porous disk, but a cathode ray tube; The photoelectric element is no longer selenium, but photocell; What the trumpet calls out is no longer a note representing a glyph, but a real letter.

Most importantly, there is an additional component in the middle called "electronic analyzer". After receiving the signal from the photoelectric element, it has to pick out the letter that matches the signal from 26 letters before it can command the speaker to read it.

A mainstream view holds that this is the first device in the world that can complete the Optical Character Recognition (OCR) task.

Photo translation AFP

Later, with the development of computer technology, OCR algorithm became more and more sophisticated. Nowadays, artificial intelligence/machine learning has injected a handful of souls into OCR.

Nowadays, OCR serves more than blind people. There may be a moment when everyone needs to copy a large paragraph of text in a picture, or take pictures of foreign characters and throw them directly to translation software. People even think that it is a matter of course to use such technology.

But the first person who made the concept of OCR possible may be Dr Edmund Founier Dalbet, who invented the photoelectric reading device more than 100 years ago.

Each city has its own main cuisine. Speaking of traditional Shaoxing cuisine, I believe that the first reaction in most local people’s minds is stinky tofu, moldy vegetable stalks, braised pork with dried plums and other dishes. For Lihai Street in Yuecheng District, the unique geographical location and natural conditions provide rich seafood ingredients for the local area because the sea head is located at the mouth of Qiantang River. Because this kind of local small sea is tender, delicious and affordable, it has gradually attracted diners from Xiaoshan, Hangzhou, Jiaxing and even Shanghai to come to Lihai to buy and try early, and gradually formed an industry featuring little seafood’s wholesale, retail and catering, which is well-known both inside and outside the city.

A morning market gathers customers from all directions.

"Today’s Xiaomei fish has a good head, and the steamed taste is very delicious." Walking from Haidong Road to Lihai Comprehensive Market, the enthusiastic stall owner sipped all kinds of seafood from the booth to reporters. Walking in front of the lined seafood stalls, there are all kinds of aquatic products such as Xiaomei fish, white jade crab, swordfish, horizontal crab and mud clam. In addition to fresh food, pickled products such as mackerel, dried fish and dried shrimp marinated with distiller’s grains are also readily available.

"Customers are here, and all they buy are little seafood caught by fishermen on the same day to ensure freshness." Gao Baijiang, the person in charge of Lihai Comprehensive Market, told the reporter that with the gradual recognition of Lihai little seafood by diners, from 7: 00 a.m. every day, the market was crowded with people who came from Shangyu and Yuecheng City to buy food early, and most of them came specially for little seafood. "Especially on weekends, some popular seafood varieties even have to be booked in advance to buy them." Gao Baijiang said.

There are nearly 140 stalls in Lihai Comprehensive Market, but there are only 17 stalls for aquatic products and seafood, because they have high requirements on electricity consumption, drainage and cleaning. In 2020, the market underwent a major renovation, upgrading facilities and equipment such as electricity and sewage, providing a better business environment for merchants and giving customers a good experience when shopping in the market.

The owners of aquatic products and seafood stalls No.5-15 are He Xinjuan and his wife. Her husband is in charge of fishing and her wife sells them in the market. "Whether you can go fishing and catch more or less is closely related to the tide and the weather." He Xinjuan told reporters that if the weather is bad and they can’t go out to sea, they won’t come to the booth for sales that day. "In business, especially seafood products, quality is the top priority." In He Xinjuan’s view, the popularity of Lihai little seafood is largely due to its characteristics: it grows in salty and light waters, and the change of salinity improves the composition of fatty acids in aquatic products and makes them more delicious.

Yidao seafood diners smell fresh and come

When they first arrive in Lihai, many people will choose to go for a walk in Lihai Old Street, in addition to catching crabs in Haitu. In ancient times, seawalls were rich in beaches, and "the tide retreats and people advance, and the tide retreats" summarized the life of fishermen in Lihai from generation to generation. Nowadays, after continuous construction and transformation, this street with a long history and culture is transforming into new beauty, which makes little seafood, the most local flavor, continue to be popular.

Wang Zengqi has such a statement in The Doctor of Fishing: The fish cooked out of the water is delicious, which is called "fresh from the water". In Lihai, the main thing to eat little seafood is "fresh water". The fish is tight, the crab is fresh and sweet, and the clams are sand-free. With the help of strong fire and simple and homely ingredients, the freshness of the ingredients is preserved to the greatest extent, which attracts the diners’ forefinger to move, and the crack of cold beer or various drinks during the dinner constitutes the "wonderful seafood" of this Lihai. During holidays, in a restaurant featuring little seafood on Haidong Road, many Shanghai and Hangzhou gourmets drove for an hour or two to punch in.

Abo Seafood Restaurant is located on Yu Haidong Road. As soon as customers enter the door, they will choose their own little seafood and cooking method through what you see is what you get. "little seafood is directly transferred to the kitchen for production after weighing, and the fresh experience from the sea to the tip of the tongue can be felt in less than 12 hours." Zhao Qin, the 42-year-old director of Abo Seafood, introduced.

Zhao Qin, a native of Lihai, has been running a seafood restaurant with her husband for nearly 20 years. "The main store is Lihai little seafood, and the dishes are affordable, which can ensure that diners can eat fresh and delicious little seafood." Zhao Qin said that in little seafood, the restaurant has special local fishermen to deliver goods every morning, and the restaurant will select the fish received to ensure the quality.

"Watching kites and eating seafood, today’s parent-child time should give full marks." At noon on April 21, with all the dishes served, Shen Yiping, who was eating at Suntory Restaurant, took out his mobile phone to take photos and sent a circle of friends in Jiugongge. "I took a break today, just to take my children out for a walk." Shen Yiping told reporters that his family lived in Tashan Street, Yuecheng District, and it was the first time to come to Lihai that day. At the kite festival, local people recommended this restaurant to them, and they chose to eat here. The reporter at Suntory Restaurant saw that although the day was a working day, there were still many diners dining, and the business was quite good.

An opportunity to undertake the Bay Area dividend

Walking on the streets of Lihai, you can still see some special place names, such as Qiliuqiu, Qiyiqiu, Qiqiqiu, etc., which were the historical imprint of the "Great Wai Tu" in that year. However, the former beaches have already become fertile soil. Lihai, a small town at the mouth of Qiantang River, has become a provincial-level economic town. "The Greater Bay Area era has given Lihai a new opportunity to leapfrog development." The relevant person in charge of Lihai Street said.

In 2019, Shaoxing Binhai New Area, one of the four strategic platforms at the provincial level, settled in Binhai, undertaking the historical mission of connecting with Greater Bay Area and serving big industries. Lihai, located in the "hub of the Bay Area", has also stepped onto the stage center of urban development.

With the gathering of more and more new industrial enterprises, the population increases. To some extent, this has promoted the development of the local catering industry, mainly in Lihai and little seafood. "There are more customers coming to eat, and there are higher requirements for the capacity, service and dishes of the restaurant." Chen Fei, the person in charge of Lihai Jiulonghai private cuisine, one of the provincial-level "Hundred Counties and Thousand Bowls" experience stores in Zhejiang Province, told the reporter that taking his own store as an example, repeat customers accounted for a large part, and many of them came to eat once and then brought their family and friends to eat again.

A blueprint for making large and small seafood

Little seafood is a traditional characteristic industry in Lihai Street. It is an important content of the construction and development of Lihai City to create a special catering culture in little seafood and enrich the business service industry in Lihai. On September 2, 2022, Lihai Street issued the Implementation Plan for the Construction of little seafood Street in Lihai, aiming at creating a strong cultural atmosphere with the theme of little seafood in Lihai through various measures and comprehensive policies.

After preliminary investigation, the street will be rebuilt and upgraded from the following aspects: defining the support policies for staying merchants, improving the supporting construction of public transportation, and standardizing the management of mobile vendors. "The street will further enhance the popularity of little seafood in Lihai, and strive to make little seafood Street in Haidong Road a model of’ eating, living, traveling and playing in Lihai’ and a key link in the construction of scenic spots and modern and beautiful towns in Lihai Street." Zhou Ganbin, deputy secretary of the Party Working Committee of Lihai Street and director of the office, said.

At the same time, the street will also open up a green channel for government services, provide smooth channels for little seafood characteristic catering enterprises in license handling, government consultation, personnel recruitment and other aspects, provide relevant policy consulting services, and optimize the cash flow of support policies. On the basis of strict control, support funds will be cashed quickly.

At present, facing the vast ocean, Lihai is striving to expand the open space and lead the industrial transformation and upgrading and the high-quality development of the city. As a traditional industry with a long history, Lihai little seafood is striving to build its brand and become a bigger industry.

　　On February 24th, a netizen nicknamed "Love is God" posted a video on the online platform, saying that his Mercedes-Benz Maibakh S680 was violently driven and tested by Zunjie without knowing it, resulting in multiple damages to the hub and body. Since then, the netizen has published a number of vehicle driving data, and the vehicle may be "violently driven".

　　On the evening of February 25, Zunjie automobile manufacturer AnhuiGroup Co., Ltd. (hereinafter referred to as "Jiangqi Group") issued a statement saying that the test vehicles were obtained through regular third-party leasing channels, and the use was clearly defined to the leasing channels in advance. "The whole test follows strict industry norms and standards, and all the data are true and reliable."

　　On February 20th, HarmonyOS Zhixing, an automobile alliance led by Huawei, held a conference on Zunjie technology. In many aspects, Zunjie S800 was compared with Mercedes-Benz Maibakh S680, and Zunjie S800 was more outstanding. According to the plan, Zunjie S800 will be officially listed in May.

　　Maibakh of 3 million yuan was violently tested?

　　Zunjie is the fourth brand launched by HarmonyOS Zhixing, an ecological alliance of Huawei smart cars, which was jointly built by Huawei and Jiangqi Group. At the Guangzhou Auto Show in 2024, Zunjie S800, the first model of Zunjie, was exhibited on a small scale. At the end of 2024, Zunjie S800 made its public appearance, with a pre-sale price of 1 million-1.5 million yuan, making it the best in HarmonyOS.

　　Maibakh S680 is the flagship product of Mercedes-Benz’s high-end series.It is famous for its administration, and it is equipped with the top V12 engine in civilian vehicles, starting at 3.327 million yuan. Maibakh S680 is also one of the best-selling executive cars in China.

　　At the Zunjie technology conference, Yu Chengdong, managing director of Huawei, chairman of BG, and chairman of BU, a smart car solution, showed a number of special functions of Zunjie S800, such as snow anti-skid test, snow climbing test and bumpy road passing test.

　　In the process, the official selected Maibakh S680 for comparison, and tested that the probability of vehicle skidding in the snow was higher, the snow climbing failed, and the tire on the rough road was flat. Zunjie S800 has no skidding when driving in the snow, successfully climbs in the snow, and can also achieve "crossing the sand without lifting" on rough roads.

　　Officially, the outstanding performance of Zunjie S800 is due to its unique global integration architecture with Huawei Turing Dragon Platform. The platform relies on the fusion perception prediction network to perceive real-time information such as road information, vehicle information and driver’s intention information, and has four characteristics: active perception, central control, intelligent reasoning and autonomous learning.

　　Turing Dragon Platform can cope with complicated snow and ice road conditions without running off or swinging its tail, climbing in snow without stalling or slipping, and it has stable tire burst control that supports 120km/h road surface before tire burst. In addition, this platform can also achieve a crab walking angle of 16, which is conducive to dealing with extreme scenes such as narrow roads and narrow parking spaces.

　　However, on February 24th after the press conference, a netizen who claimed to be the "owner" of Maibakh S680 who lost control at the Zunjie S800 press conference posted a video saying that his car was taken for violent driving and testing without being informed or informed. On January 21, the vehicle was towed back and sent to the 4S shop for inspection. The "owner" found that the front of the car and the wheel hub were damaged.

　　Since then, the "owner" has voiced again, and disclosed his ID card, driving license and other documents, as well as the driving record of Maibakh S680. According to the driving records, the car was driven to yakeshi, Inner Mongolia Autonomous Region and Xiangyang National Automobile Quality Supervision and Inspection Center in Hubei Province for dozens of tests in January this year.

　　Jiang qi responded late at night

　　On the evening of February 25, Jiangqi Group responded, saying that "the relevant test videos show the excellent performance of vehicles under extreme conditions in a rigorous and professional way. The whole test process follows strict industry norms and standards, and all data are true and reliable. "

　　At the same time, Jiangqi Group said that the test vehicles were obtained through regular third-party leasing channels, and the use was clearly defined to the leasing channels in advance. In this process, the troubles brought to relevant parties are being actively communicated and resolved through consultation.

　　Times Weekly reporter asked the "owner" about the follow-up matters and the communication between the enterprise and it, and has not received a reply so far.

　　At the press conference, HarmonyOS Zhixing exhibited several test fragments of Zunjie S800 and Maibakh S680, and Zunjie S800 performed better. However, Yu Chengdong has repeatedly said that Maibakh S680 has also performed very well in many aspects and is worth learning.

　　On February 21st, the day after the launch, at the 25th Annual Meeting of Yabuli China Entrepreneur Forum 2025, Duan Jianjun, President and CEO of Beijing Mercedes-Benz Sales & Service Co., Ltd., said that many brands took Mercedes-Benz models as the targets of benchmarking and comparison at the new car launch, and Mercedes-Benz did not reject or fear being benchmarked and compared.

　　"Whether in product technology or service, reasonable benchmarking is actually to promote the progress of the industry with Mercedes-Benz standards and bring positive promotion to the whole industry." Duan Jianjun said: "For unreasonable and wrong benchmarking, Mercedes-Benz will not give up making solemn representations, or even using legal weapons to defend the rights and interests of the brand."

　　CCTV News:The flow of people during the National Day holiday will inevitably increase, which will lead to the risk of epidemic spread. So what are the safety tips for people who really need to travel across regions in terms of travel and epidemic prevention?

　　Lei Zheng Long, Director of the Department of Communication and Prevention of the National Bureau of Disease Control and Prevention, first-class inspector:If you really need to travel, you should know the epidemic situation of the destination and don’t go to the county where the middle and high risk areas are located. Personal health monitoring should be done before going out. If suspicious symptoms appear, it is recommended to cancel the travel plan in time and seek medical advice as soon as possible.

　　Secondly, according to the regulations, hold the negative certificate of nucleic acid test within 48 hours and take the plane, high-speed rail, train, inter-provincial long-distance passenger bus, inter-provincial passenger ship and other means of transportation to try to stagger the peak; Personal protection should be done during the journey, a safe distance should be kept, masks should be worn, and hand hygiene should be done to reduce people gathering and walking around in the vehicle.

　　Finally, when arriving at the destination, actively cooperate with the local government to do a "landing inspection". In accordance with the relevant requirements of hotels, hotels and crowded places such as tourist attractions, take the initiative to scan the code and register, and show negative proof of nucleic acid testing that meets the time requirements. Once an epidemic situation occurs in a tourist destination or a passing place or it is listed as a medium-high risk area, it is necessary to implement local prevention and control regulations, and those who have returned to their place of residence should take the initiative to report to their communities.
