CCTV News:On November 16th, the website of China CDC published the monitoring situation of monkeypox epidemic in October 2023. From October 1 to 31, 2023, 127 newly confirmed cases of monkeypox were reported in China (excluding Hong Kong, Macao and Taiwan), including 17 cases in Guangdong, 16 cases in Shanghai, 15 cases in Zhejiang, 13 cases in Beijing, 12 cases in Sichuan, 8 cases in Henan, 7 cases in Jiangsu, 6 cases in Hubei, 6 cases in Guangxi, 5 cases in Hunan, 4 cases in Heilongjiang, 4 cases in Fujian, 4 cases in Shandong and 4 cases in Shandong.　

　　According to epidemiological investigation and analysis, the epidemic situation has the following characteristics: First, 98.2% of the cases are male, 90.0% of the cases are men who have sex with men, and 2 cases are women. Second, other contact methods have low risk of transmission. Only two close contacts except sexual contact were infected. Third, 97.2% were found by active medical consultation, 1.8% were found by follow-up screening of close contacts, and others were found by active reporting. Fourth, the clinical manifestations of most cases are typical, mainly for fever, herpes, lymphadenopathy and other symptoms.　

In daily life, parents tend to confuse children’s common cold with influenza. In fact, there are great differences between them in pathogen, infectivity, symptoms and medication. Parents should carefully distinguish whether their children are suffering from the common cold or the flu, and take medicine according to the symptoms.

Common cold

The common cold is mainly caused by viruses, and children will have symptoms such as stuffy nose, runny nose, sneezing, coughing and fever. The common cold is often a mild self-limiting disease, which can be gradually relieved without taking medicine.

In infants and young children, the symptoms of the common cold are usually more serious on the second to third day, and gradually relieved on the tenth to fourteenth day. A few children may cough for 3-4 weeks. Older children and adolescents generally have cold symptoms gradually subsided in 5-7 days, and children with basic lung diseases may last longer.

There is no specific medicine for the common cold. Taking medicine is mainly to relieve symptoms and make children feel less uncomfortable. The commonly used therapeutic drugs for relieving cold symptoms are shown in Table 1.

It should be noted that children should not be given cold medicine containing codeine. Although codeine has a strong antitussive effect, long-term use may cause physiological dependence and addiction. National Medical Products Administration’s announcement on revising the instructions for cold medicines containing codeine clearly points out that it is forbidden for children under 18 to use cold medicines containing codeine. Then, how to relieve the mild cold symptoms of children?

When the body temperature caused by fever is above 38.2℃, children over 2 months old can use acetaminophen to reduce fever, and children over 6 months old can use acetaminophen or ibuprofen to reduce fever. For the symptoms of nasal congestion and runny nose, it is suggested to relieve the symptoms by dripping salt water into the nose, spraying nose, nasal irrigation, etc. Children under 6 years old are generally not recommended to use drugs (such as compound cold medicine) to relieve the nasal symptoms, because these symptoms will generally gradually relieve themselves, and adverse reactions may occur when using drugs. If you have a cold accompanied by cough, you can replenish water appropriately, which will help to dilute sputum and relieve respiratory mucosa. Children over 1 year old with common cold can take honey or honey water to relieve their cough. Honey has a mild cough relieving effect on night cough. It should be noted that children under 1 year old should not take honey, because it will increase the risk of botulinum poisoning.

Parents need to pay special attention to that children need to seek medical attention as soon as possible in the following situations: infants less than 3 months old have symptoms such as fever and cough; After taking antipyretics, the fever still persists or persists for 3 days; Persistent nasal symptoms, such as stuffy nose, runny nose, sneezing, etc., have lasted for more than the course or degree of the common cold; Abnormal conditions such as dyspnea, confusion and ear pain occur.

So, how to prevent children from catching a cold? The most important thing to prevent colds is to wash your hands frequently. It is best to use running water when washing your hands, and tell your child to rub it with hand sanitizer or soap for at least 20 seconds. In addition, we should pay attention to indoor ventilation, take children to crowded public places less, and try to wear masks when going out. If parents catch a cold, they should be isolated and reduce contact with their children. Pay attention to the combination of meat and vegetables in diet, ensure nutrition, take children to exercise more and ensure enough sleep time to enhance their physique and improve their immunity.

Common medication problems of common cold

Q: Can antipyretics and compound cold medicines be taken together?

A: no. Compound cold medicine usually contains antipyretic ingredients, which can easily lead to repeated medication and toxic and side effects when taken together with antipyretics. It is best for parents to choose a single ingredient medicine for their children. If you use a compound cold medicine, you must read the instructions carefully before using it, especially the ingredients, to know whether there are repeated drugs.

Q: Do Chinese patent medicines have any side effects?

A: Chinese patent medicines also have side effects. Although the adverse reactions written in the instructions of many Chinese patent medicines are unclear, this does not mean that they have no adverse reactions, and Chinese patent medicines are not necessarily safer than western medicines.

Q: Do children need antibiotics for their common cold?

A: no need. Common cold is caused by virus infection, and antibacterial drugs are mainly aimed at bacterial infection. The use of antibacterial drugs is not only ineffective for common cold, but also may cause bacterial resistance. Therefore, the common cold does not need antibiotics, unless the doctor clearly diagnosed bacterial infection or secondary bacterial infection.

Q: Can children take oseltamivir for a common cold?

A: no. The common cold is mainly caused by rhinovirus and coronavirus, while oseltamivir is aimed at influenza viruses, including influenza A and influenza B viruses, so oseltamivir is not symptomatic for treating common cold.

flu

Influenza is an acute respiratory infectious disease caused by influenza virus, which can be divided into four types: A, B, C and D. The most common type of influenza is seasonal influenza, which occurs in autumn and winter and is mainly caused by influenza A and B viruses.

Children’s influenza often starts suddenly, the main symptom is fever, and the highest body temperature can reach 39~40℃, often accompanied by chills and chills. Children will also have headaches, muscle aches, fatigue, loss of appetite and other manifestations. Cough, sore throat, runny nose and stuffy nose may also occur, and a small number may have digestive tract symptoms, such as nausea, vomiting and diarrhea. The symptoms of influenza in infants and young children are often not as typical as those in children, and may only be fever and cough. Newborn influenza is relatively rare, but complications often occur, such as pneumonia and dyspnea.

Mild influenza is often similar to the common cold, but its fever and systemic symptoms are more obvious. Severe children will have viral pneumonia, secondary bacterial pneumonia, acute respiratory distress syndrome, shock, disseminated intravascular coagulation, cardiovascular and nervous system and other extrapulmonary manifestations and various complications.

Influenza patients and recessive infected people are the main sources of seasonal influenza infection, mainly through droplets of respiratory secretions, but also through direct or indirect contact with oral cavity, nasal cavity, eyes and other mucosa. Influenza virus is easy to produce new mutant strains, so it can spread widely among people, causing repeated infections and diseases. Therefore, we must pay attention to it and do our best to prevent it.

Different from the common cold, influenza has a "nemesis", that is, neuraminidase inhibitors. At present, the drugs listed in China include oseltamivir, zanamivir and palamivir. Among them, oseltamivir is the most widely used anti-influenza drug for adults and children at present, and its best administration time is within 48 hours after the onset of flu symptoms, and it is also effective after 96 hours after the onset of flu symptoms. Specific therapeutic and preventive doses can be found in Table 2. Although vaccination is the best way to prevent influenza virus infection, oseltamivir can be recommended for people who cannot be prevented by vaccine and the following key children in the outbreak of influenza.

The recommended drug prevention population includes: high-risk children who cannot be vaccinated with influenza vaccine, or children with immune abnormalities who do not respond to the vaccine; High-risk children within 2 weeks of vaccination; Family members or caregivers who are in close contact with non-immunized high-risk children or infants younger than 24 months; In order to control the outbreak of influenza, it is used in children who have not been immunized or in children’s gathering places (such as kindergartens); Prevention after exposure of family members; Prevention of patients with high risk of influenza complications and close contact with influenza.

Vaccination against influenza can significantly reduce the probability of influenza in children and the risk of serious complications. Therefore, parents are advised to take their children to get the flu vaccine in time every year. Generally, it is planted indirectly from September to December every year, and it is best to complete immunization before the end of October. Children aged 9 and over are advised to take one dose in one flu season. For children aged 6 months to 8 years, it is recommended to vaccinate two doses for the first time, with an interval of one month. But not all children are suitable for vaccination, and infants less than 6 months old or children who are allergic to any component of the vaccine are not suitable for vaccination. In addition, if the child suffers from mild to moderate acute diseases, it is recommended to vaccinate after the symptoms subside.

When the child has the following situations, he should pay attention to seek medical attention in time: dyspnea or shortness of breath, which can not be relieved after cleaning the nasal cavity; Crying low, crying less, not having good eye contact with parents, poor spirit and listlessness; Drink less water, or there are signs of dehydration, such as no tears when crying, decreased urine output (dry diapers), dry mucous membranes such as lips, tongue and eyes, and skin like dough, which cannot be quickly recovered after gently pinching the skin; Severe or persistent vomiting; Poor appetite, significantly reduced eating; Persistent fever, with or without convulsions; Fever with rash.

Common drug use problems of influenza

Q: Can infants under 1 year old take oseltamivir granules?

A: Although the minimum age of the population suitable for oseltamivir granules is 1 year old, the US Food and Drug Administration has approved that oseltamivir can be used for infants over 2 weeks old. The British Ministry of Public Health guidelines also suggest that infants under 1 year old can use it. China’s "Expert Consensus on Diagnosis and Treatment of Children’s Influenza (2015 Edition)" puts forward that oseltamivir can be used for influenza treatment in children of all ages and influenza prevention in children over 3 months old. According to the above evidence, infants younger than one year old can take oseltamivir granules, but it is an over-the-counter drug in China at present.

Q: The child’s condition has improved after taking the medicine for 3 days. Can he stop taking the medicine?

A: Due to individual differences, some children may feel better after two or three days of medication, but they are not sure whether their illness will recur. It is suggested that they should take medication according to the course of treatment for five days.

Q: Can oseltamivir take the place of influenza vaccine to prevent influenza?

A: Drug prevention is generally only used as an emergency temporary preventive measure and cannot replace vaccine prevention. Vaccination against influenza is the first choice to prevent influenza.

Q: Can I treat the flu with antibacterial drugs?

A: no. Antibacterials only kill or inhibit bacteria, but have no effect on influenza virus.

　　This time, OTA 5.0, in terms of intelligent driving, intelligent space and intelligent extended range, all three platforms have been fully upgraded, so that users can drive new cars in the New Year.

　　It should be noted that in terms of smart space, Max, Pro and Air models will be upgraded simultaneously; In terms of intelligent driving, the Max model will be upgraded to AD Max3.0, and the Pro and Air models will realize high-speed intelligent driving, full-scene assisted driving and more intelligent parking and active safety under the BEV architecture in the first half of next year.

　　Moreover, Li ONE’s OTA 3.4 will also be launched on December 26th, adding functions such as traffic light countdown of Gaode map, mobile version of task master, co-pilot screensaver, parking photo overhead view, energy consumption distribution statistics and so on.

First, the new intelligent driving: AD Max3.0 is fully upgraded, with new technologies and new experiences.

More exciting videos are all on the car home video platform.

　　1. Intelligent driving can be used all over the country.

　　In terms of intelligent driving, two platforms, AD Max and AD Pro, have accumulated large-scale training mileage based on the national super-large intelligent driving fleet owned by LI.

　　Based on this, the algorithm model has been re-architected, and it has been upgraded from AD 2.0 to AD 3.0. From the original modular algorithm architecture based on multiple small models and artificial rules, it has been upgraded to an end-to-end algorithm architecture based on large models.

　　In the perceptual algorithm, AD Max 3.0 adopts BEV big model, which is more advanced in the visual field, and Occupancy occupies the network; The planning algorithm is gradually switched to the spatio-temporal joint planning algorithm, and the optimal driving trajectory can be planned in milliseconds; At the same time, the MPC model predictive control algorithm is updated to achieve low time delay, high accuracy of steering, acceleration and braking, which balances safety, comfort and traffic efficiency to the extreme.

　　The new version of high-speed intelligent driving has the ability to avoid construction obstacles and change lanes in game. It is worth noting that AD Pro 3.0 will also complete the switching of all the above algorithm architectures in the first half of next year.

　　　2, assisted driving, can be used all over the world

　　Full Scene Assisted Driving (LCC), which can automatically identify traffic lights and automatically start and stop to complete traffic. It has the ability to "brain-fill" lane lines, and can support the traffic at large intersections with no lane lines of 100 meters at the longest, and the diversion and confluence of straight intersections can smoothly and independently switch lanes.

　　　3. Intelligent parking is better than mine.

　　Leave the car and park, and the narrow parking space is easy to stop. Separation of people and vehicles makes parking more flexible. The mobile App can be parked with one button, and the broken parking space can also be stopped. Intelligent scene recognition, active folding rearview mirror. Stop in a narrow parking space and bid farewell to tiptoe and abdomen.

　　This time, parking service function has been added, which can realize multi-layer basement to help you stop. Not only that, this time, it also supports multi-storey basements to drive, and ramps and flats can be opened. The access route is flexible, and you can reverse the car when you encounter obstacles. What’s even more rare is that parking service also supports autonomous learning in the background, so that users can learn to complete the user’s garage path without complicated memorizing the operation process of parking spaces, and support multi-storey traffic and reversing.

4, active safety, less major accidents

　　For the emergency braking (AEB) function, it is reported that AD Max 3.0 is fully aligned with Huawei’s AD project, and the maximum braking speed of AEB is 12kph, far exceeding the industry standard. This is due to the full integration of BEV sensing architecture and Lidor, which improves its AEB performance and can automatically stop at a maximum speed of 110 km/h. For the two-wheeled vehicle "ghost probe" crossing, you can cope! 5-120 km/h wide speed working range, covering all day and night.

　　In this OTA 5.0 upgrade, full-scene intelligent driving will cover all highways, all urban loops and urban roads in 110 cities across the country.

　　In the first half of 2024, AD Pro will also welcome its own version 3.0 and push it to users of full Pro and Air models. The BEV model will reshape AD Pro’s high-speed intelligent driving, full-scene assisted driving, intelligent parking and active safety.

Second, to create a smart space, a brand-new AI ideal classmate, and a self-developed big model Mind GPT get on the bus.

　　In OTA 5.0, the biggest change of ideal students is the introduction of Mind GPT. For what is Mind GPT? You can think of it as an ideal self-developed multimodal cognitive model. (Mind GPT is still in beta. )

　　It is reported that LI built the original base model of Mind GPT from 0 to 1, and the model structure adopted the self-developed TaskFormer neural network architecture. Based on the scenes of car use, entertainment, travel and so on, a series of trainings were conducted by using SFT, RLHF and other technologies. Let Mind GPT have three abilities of understanding, generation, knowledge memory and reasoning.

　　So what is the level of Mind GPT in the industry?

　　At present, C-EVAL, an authoritative evaluation list of Chinese large language models in China, covers 52 disciplines in humanities, social sciences, science and engineering, and Mind GPT ranks first among 58 large models participating in the evaluation; At the same time, there is also an evaluation list covering 67 subject areas from basic disciplines to advanced majors, and Mind GPT also won the first place and won the double champion.

　　Mind GPT has tailored more than 1,000 exclusive abilities covering 111 fields based on the key scenes of ideal students, and it is still evolving and growing rapidly.

　　What’s even more rare is that Mind GPT is the only big model in the industry that can be used without any instruction words, and it is also a big model built around the car scene. It is not only knowledgeable, but also can query the Internet information in real time, and at the same time support all seats in the whole car to be used. Everyone in the whole family can have a car assistant, a travel assistant, an entertainment assistant and an encyclopedia "teacher". It is a super powerful pure self-developed big model that integrates the whole scene.

　　It also has an ideal classmate with an all-round evolution of listening sense and execution ability, and supports the free speaking of dialects, the free speaking of instructions, the concise mode and the ability to avoid waking up all the time. In addition, it also has a powerful browser function, which makes the life of car networking infinite.

Third, intelligent extended range surprise upgrade winter battery life

　　In winter, LI continuously iterates through the algorithm, and continuously improves the endurance of the ideal L-series vehicles from OTA 4.6.2.

"Ideal L7"

　　After upgrading OTA 5.0, REV 3.0 has brought a 15%-20% increase in pure electric cruising range for L-series models, making the family’s winter travel bid farewell to mileage anxiety.

　　The ideal L series is equipped with a full-stack self-developed XCU vehicle central domain controller, which is the first to adopt an A-core intelligent chip in the field of vehicle control, and provides a solid foundation for the algorithm iteration of REV 3.0 with strong computing power. Innovative intelligent power prediction algorithm can accurately predict the discharge power of batteries and motors in milliseconds, and achieve more accurate discharge control, which can not only ensure the safety of vehicles, but also fully release the potential of batteries and improve the maximum discharge capacity by 4.1%. For vehicle-mounted electrical appliances with high power consumption, such as air conditioning and seat heating, the new algorithm optimizes the power consumption through smarter detection and control means, and greatly improves the power efficiency while ensuring comfort.

　　On December 3, Beijing held a press conference on epidemic prevention and control. Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention, stressed that people at risk, such as those who have an intersection with the published case trajectory and close contacts who have received phone calls from other provinces, should immediately report to communities, units, hotels, etc., and cooperate with health monitoring, nucleic acid detection and other prevention and control measures. If symptoms such as fever and cough occur, do not participate in social activities, do not take public transport, do not ride the Internet to get a car, wear a mask, and go to a fever clinic in a nearby hospital as soon as possible, and do not seek medical treatment by yourself.

Pang Xinghuo said that he insisted on not leaving the country and not leaving Beijing in the near future. Pay close attention to the progress of the epidemic situation in the areas where the epidemic has recently occurred in China; Do not travel or travel to high-risk areas and areas where confirmed cases are reported; Do not mail-order goods from overseas high-risk areas unless necessary, and carefully mail-order goods from areas where there are local epidemic reports in China. Airports, railway stations, road checkpoints and other transportation hubs, hotels, hotels, homestays and other units have strengthened investigation and control, and strictly implemented various prevention and control measures such as temperature measurement and code inspection and nucleic acid certificate inspection in accordance with relevant regulations.

On July 23rd, local time on July 21st, Arm’s first 32-bit microprocessor Plastic based on flexible plastics was published in the top academic journal Nature.

PlasticARM consists of 56340 NMOS(N-type metal-oxide-semiconductor) transistors and resistors. PlasticARM adopts thin film transistor (TFT), which can be bent to a radius of curvature of 3 mm..

This microprocessor is manufactured by PragmatIC, a British flexible IC manufacturer invested by Arm. It adopts FlexLogIC 200mm wafer process, and the chip process is 0.8μm, which has the potential of low-cost mass production.

In the past 20 years, there have been low-cost flexible solutions for memory, sensors, batteries and light-emitting diodes. However, as for microprocessors, people can only integrate the silicon-based microprocessor die on the flexible substrate, thus obtaining a flexible microprocessor. However, this scheme needs to adopt the traditional chip manufacturing process, and the cost is too high, which is far from meeting the requirements of intelligent daily necessities.

According to the paper, PlasticARM does not want to replace the traditional silicon-based chip, but it can really make daily necessities such as beverage bottles, food packaging, clothing, bandages and wearable devices intelligent.

▲ Mike Muller, CTO of ARM at that time, was showing samples of plastic chips.

Based on this, as early as 2015, Arm revealed the research and development plan of the system on a plastic chip (SoC) based on Cortex M0. On November 24th, at Arm TechCon, Mike Muller, then CTO of ARM, showed samples of plastic chips. He also hinted that this design can be applied to low-power application scenarios such as the Internet of Things.

During the event, Mike Muller had a telephone conversation with Scott White, CEO of PragmatIC. But PragmatIC was still busy developing an analog component library at that time, and its timetable was not clear.

Time has passed today, and the flexible plastic microprocessor that has been running for 6 years has finally been officially published. Does this mean that the pace of the fully intelligent era is approaching?

PlasticARM is manufactured in its fab-in-a-box wafer factory in Sedgefield, England, using the 0.8μm process of PragmatIC.

According to the researchers, PlasticARM has more than 18,000 logic gates, which is 12 times higher than the previous flexible integrated circuit, and it is by far the most complex flexible integrated circuit. On the basis of Plastic, people can build a low-cost, flexible intelligent integrated system and realize the real "Internet of Everything".

PlasticARM is not perfect either. It is reported that Arm is developing a low-power unit library, which can support plastic design of up to 100,000 doors to solve the heat dissipation problem of flexible plastics. However, practical NMOS technology may not be able to realize the migration of 100,000 gates, and CMOS technology is needed, which may take several years.

Nevertheless, researchers predict that in the next decade, PlasticARM will integrate more than 1 trillion products into the digital world, bringing reform opportunities for life, scientific research, business and other dimensions.

Compared with the commonly used metal-oxide-semiconductor field-effect transistor (MOSFET), Arm adopts thin film transistor (TFT), which has obvious advantages in thickness, integration and manufacturing cost.

In the manufacturing process, the researchers chose flexible electronics manufacturing technology, which is also known as the naturally flexible processing engine. The metal oxide thin film transistor manufactured by this technology has low cost and the size also meets the requirements of large-scale integration.

▲ flexible Arm Cortex-M SoC with I/O.

It is worth mentioning that PlasticARM is more universal than the recently released flexible machine learning hardware, and also supports a rich instruction set, which can be used to write various applications such as machine learning.

PlasticARM is mainly divided into three levels, namely 32-bit CPU；; 32-bit processor including CPU and CPU peripherals; And a system-on-a-chip (SoC) including a processor, a memory and a bus interface, namely a PlasticARM.

Its CPU is Arm Cortex-M CPU supporting Armv6-M architecture. Different from Cortex-M0+,in order to save CPU area, the registers of Cortex-M CPU are placed in RAM. Moreover, the two CPUs are binary compatible with each other, and are also compatible with other CPUs in the same architecture series.

Because the SoC is compatible with Arm Cortex-M processors, it can be equipped with existing software/tools without building a new software tool ecosystem.

The processor consists of a CPU and an embedded vector interrupt controller (NVIC) closely coupled with the CPU, which is used to handle interrupts from external devices.

In addition to the 32-bit processor, SoC also has memory (ROM/RAM), AHB-LITE interconnection structure, logic interface, bus interface and other parts.

▲ PlasticARM structure (left) and comparison with two CPU models (right)

With the advent of Plastic, wearable devices, electronic skin, etc. will usher in new development opportunities. Although its manufacturing process is lower than that of silicon-based chips, Plastic’s characteristics of low cost, low power consumption and using existing software tools may become a good opportunity for many industries to break through.

Although PlasticARM has not been commercialized, looking forward to the future era of "Everything is Smart", today will be an important node.

Original yang yang yang yang yang doctor from the album.

Author | Yang Yang (doctor of reproductive andrology, doctor of medicine, doctor of philosophy)

Hello, everyone. Some time ago, there was a heated discussion on Weibo.

There is a young woman in Shenzhen who goes out for dinner with a male friend. As a result, when she went to the toilet halfway, the man added some white powder with unknown composition to her cup.

Fortunately, the clerk of the restaurant stepped forward in time and told the woman to save her from disaster.

Then it got into Weibo, and even exploded three hot searches, and public opinion was in an uproar. The Futian District People’s Procuratorate also intervened in the investigation and issued relevant official notices:

At first, Dr. Yang thought it was an old scene of drug rape by acquaintances (because 80% of rape cases occurred between acquaintances).

But I don’t know if I don’t see it, but I die when I smile. Because this man is trying to rape women with this kind of thing.

Of course, in fact, the notice of Futian District Procuratorate is also flawed, because they got the name of this medicine wrong.

It’s not called tadalafil, but tadalafil.

(But not this kind of Lafite …)

In fact, it is a kind of viagra drug.

Of course, it is undeniable that this man is really bad, but fortunately, he is still stupid.

Therefore, although he has a thief’s heart and courage, but also put it into action, but even if he really succeeded, let the woman drink the water containing tadalafil, it will not cause any adverse effects on this woman.

Then let’s analyze, why do you say this man is an idiot?

There is a great probability because he has a big misunderstanding about this drug.

01

In fact, there have been a lot of misunderstandings about viagra drugs.

So that every time Dr. Yang prescribes this kind of medicine for patients, it is inevitable to explain its mechanism of action in detail, and then patients will agree to try it with a grain of salt.

Brother, it’s just a medicine, as for it.

Others simply refuse and insist on taking Chinese medicine to recuperate. ……

In fact, only this kind of drug is the first choice for treating ED, which has been officially certified by international guidelines for diagnosis and treatment.

Its scientific name is actually called "type 5 phosphodiesterase inhibitor" (a string of Chinese characters that everyone knows but don’t know what it means when combined).

English abbreviation is "PDE5-i"

The original intention of this drug was to lower blood pressure. As a result, in the clinical trial stage, it was found that the effect of lowering blood pressure was not good, but the patients who took the drug were unwilling to return the leftover medicine.

After careful questioning, I found that this medicine actually had the unexpected joy of improving erectile function.

And its mechanism of action is actually very simple. You can think of it as a muscle relaxant, that is, a valve switch.

However, the muscle it relaxes at a fixed point is the cavernous smooth muscle wrapped outside the cavernous artery of the penis.

This circle of muscles is tense, the artery is flat, the blood does not flow in, and Tintin is weak.

This muscle is flabby, the artery is full, blood flows in, and Tintin stands up.

It’s that simple.

02

But it is such a simple medicine that has caused all kinds of rumors that have been overwhelming for a long time.

The following are some common misconceptions about PDE5-i drugs:

one

"PDE5-i" equals an aphrodisiac.

This rumor has been around for years, but it is widely circulated.

I guess the boy who drugged Shenzhen is also out of a similar idea. It seems that a woman who eats this will have sex with someone.

This is understandable, because the "aphrodisiac" that can improve sexual function in our traditional little Huang Wenli can not only improve hardness, but also improve sexual desire.

But unfortunately, even if you give a man this kind of medicine, he won’t have any idea of rising desire, because this medicine has nothing to do with desire at all.

A valve switch, which doesn’t involve your brain at all, can improve your sexual desire?

2

After eating, it will always be hard.

In fact, taking Viagra can only help you restore normal erectile function, and there is a premise.

That is: you must have effective sexual stimulation and arousal to work.

It doesn’t mean that after you eat it, like a salted fish, Tintin will stand up by himself.

If there is no stimulation, people are fine, why should they get up and work?

Have you considered Tintin’s feelings?

And tadalafil is effective for 36 hours. If you eat one, you have to be hard for two days. Isn’t Tintin already ischemic and necrotic?

Is it necessary to cut off a tintin every time you eat a viagra?

three

"PDE5-i" will "hurt the body"

It is undeniable that some people may have some side effects after taking such drugs.

Common ones include blushing and rapid heartbeat.

Some people will have some back or muscle aches, and a few people will have a temporary blue eye.

But other than that, no adverse reactions have been found at present, and it will not "hurt the body."

It’s just a muscle relaxant. What kind of body did it hurt, dear?

03

Then again, what will happen if that stupid bad man in Shenzhen really succeeds in drugging?

That is to say: what will happen if a woman eats tadalafil?

At present, some studies have found that giving tadalafil to middle-aged and elderly women may help to improve their various female sexual dysfunction due to menopause.

Including sexual arousal difficulties, low sexual satisfaction and so on.

But for young women, it doesn’t matter a dime.

On the 21st, the joint prevention and control mechanism of the State Council held a press conference to introduce the safety and effectiveness of vaccines in COVID-19. Look at the main points and sort out ↓

At present, low-risk areas in China hold a "green code" for healthy traffic, and they can travel in an orderly manner on the premise of normal temperature measurement and personal protection, and all localities are not allowed to overweight without authorization.

As of 24: 00 on March 20th, 74.956 million doses of Covid-19 vaccine were reported nationwide.

At present, the COVID-19 epidemic is still prevalent in the world, and no one can be immune to it. Vaccination is the most effective means to prevent and control the COVID-19 epidemic.

According to the existing production arrangements, the annual vaccine output can fully meet the vaccination needs of the whole country.

At present, COVID-19 vaccination has been started for the elderly over 60 who are in good physical condition. Vaccine research and development units are also accelerating the research and development process. After clinical trials have obtained sufficient safety and effectiveness data, large-scale vaccination will be carried out for the elderly over 60 years old.

At present, the four vaccines listed in China have been examined and approved by the competent government departments, which are safe and effective. Because the varieties of vaccines purchased in different provinces and cities may be different, everyone needs to be vaccinated as soon as possible according to the unified arrangements of the provinces and cities where they are located.

In China, people still need to wear masks indoors or in closed places where people gather, regardless of whether they are vaccinated or not.

For the time being, the entry vaccinators will not be exempted from testing and isolation measures.

Wang Huaqing, chief expert of immunization program of China CDC, said that at present, China CDC is still further understanding and verifying this case. Our country has approved the vaccines for conditional marketing or emergency use abroad. In the early phase III clinical trial, the protective effect is to protect most people from getting sick, and its effect of preventing severe diseases is more obvious. From the post-marketing evaluation results of the vaccines currently used abroad, after vaccination, there are still some individuals who fail to protect, and the reasons for the failure still need to be studied and investigated.

In addition, they should carefully refer to the special requirements for physical conditions in the college enrollment regulations, avoid the restricted majors according to their own conditions, and choose their volunteers reasonably. Physical examination conclusions are generally divided into these situations:

First, it is unqualified, "colleges and universities can’t accept it." This kind of candidates’ physical health is unqualified, mainly because they have serious diseases, so they should be treated first. Specifically, corresponding to the provisions listed in the first part of the Guiding Opinions, that is, those who suffer from the following diseases may not be admitted to the school:

He is nearly 2 meters tall and weighs 300 Jin-this was the deepest impression left by Hao Zhangang, a rich businessman in Ordos, to a person who met him for the first time.

On August 20, 2021, Baotou City Public Security Bureau issued a notice saying that the "5.15 Task Force" set up by the Municipal Anti-vice Office destroyed the suspected criminal gang headed by Hao Zhangang in Ordos City, Inner Mongolia for many years and arrested 12 criminals. On August 18th, Hao Zhangang was arrested by Baotou City Procuratorate according to law.

Hao Zhangang data map

According to the notice of Baotou Public Security Bureau, Hao Zhangang gang obtained the land use right from the government in the name of a first-class land development enterprise, and then illegally transferred and resold the land use right to real estate developers at a high price, seeking illegal interests in the process of illegally transferring and reselling the land. It is suspected of illegal transfer and reselling of land use rights and other illegal and criminal acts, and the areas involved mainly include Ordos, Bayannaoer, Tongliao and Hohhot.

In Ordos, Hao Zhangang is a well-known real estate businessman. China News Weekly visited Ordos and learned that the arrest of Hao Zhangang gang was directly related to the Ordos Forest Park project that had been unfinished for many years. In 2006, Dongsheng District Government of Erdos signed an agreement on Forest Park Development with Wan Yu Jiaye Investment Management Co., Ltd. of Inner Mongolia (hereinafter referred to as "Wan Yu Jiaye") controlled by Hao Zhangang, and the company developed the forest park. In exchange, Wan Yu Jiaye got 8,000 mu of construction land. However, in the past 15 years, the forest park has not been completed, and Wan Yu Jiaye, which won the project, has transferred the construction land to dozens of enterprises in the past few years, so that Hao Zhangang’s business is getting bigger and bigger, and even his "forest park model" has blossomed in many places across the country.

A real estate businessman without development qualification

Hao Zhangang, a native of Erdos, was born in an ordinary worker’s family in Wulan Town in 1962. After finishing high school in 1980, he joined the army and settled in the family building of Beijing Air Force Logistics College. Shortly after joining the army, Hao Zhangang was attached to the army to do business in the sea. One of his Hainan subordinates recalled that Hao Zhangang once talked about it at the wine table, and his "first bucket of gold" was earned by "speculating in uncompleted flats" in Hainan in the early 1990s. "Before the collapse of the Hainan property market, he got the news and got away after changing hands, and he even laughed and said that the person who took his project was the" taker ".

Around 2006, Hao Zhangang saw the huge opportunities in his hometown Ordos real estate and returned to Ordos as a "Beijing boss". At that time, Ordos, with coal as its pillar industry, had a rapid urbanization momentum, and local departments were also actively investing in attracting investment. Wu Tian, then head of the land acquisition unit of Dongsheng District Land Bureau in Erdos, told China Newsweek that when Hao Zhangang came to discuss cooperation with the government, he revealed that he had invested 1 billion yuan in Dongsheng District. "At that time, there was also a discussion within the government, saying that Hao Zhangang was worthy of being a big boss from Beijing."

On August 8, 2006, Hao Zhangang registered and established Wan Yu Jiaye in Ordos with a registered capital of 70 million yuan. On November 7th, 2006, Wanyu Jiaye signed the Forest Park Development Agreement with Dongsheng District Government of Ordos City, and Dongsheng District Government handed over the plots located in Dongsheng District, north of South Ring Road, east of Santaichuan, south of Textile Street and west of Tongchuan Road, with a total area of 17.9 square kilometers and nearly 27,000 mu, to Wan Yu Jiaye for development. According to the agreement, Wanyu Jiaye will complete the construction of the forest park within five years, and bear the land acquisition compensation, resettlement fees and other expenses during the construction period, and undertake the construction of infrastructure and six roads in the forest park, with an investment of not less than 80 yuan per square meter. Based on the above conditions, Wanyu Jiaye can choose 5000 mu of construction land in the park.

Wu Tian introduced that this business of exchanging infrastructure for construction land is not an isolated case in Ordos. Take Wanzheng Real Estate, the largest real estate company in Dongsheng District, as an example. The infrastructure and old renovation in Tiexi area of Dongsheng District are operated by Wanzheng Real Estate, and the government uses the construction land to "pay the cost".

As Wanyu Jiaye does not have the qualification of real estate development, in 2008, Hao Zhangang introduced Nanjing Golden Eagle International Group Co., Ltd. with 30% shares of Wan Yu Jiaye. On May 8, 2008, Golden Eagle International, as the major shareholder, led the establishment of Inner Mongolia Golden Eagle Wanjia Real Estate Development Co., Ltd. (hereinafter referred to as "Golden Eagle Wanjia"). In the same month, it signed a tripartite agreement with Dongsheng District Government and Wan Yu Jiaye again, stipulating that some of the development and old renovation projects in the previous agreement would be handed over to Golden Eagle Wanjia with real estate qualifications.

After signing the Forest Park Development Agreement, as of July 8, 2010, Dongsheng District Government and Wanyu Jiaye have successively signed nine supplementary agreements to improve the forest park project. Through nine supplementary agreements, Wan Yu Jiaye obtained the construction land of Forest Park from 5,000 mu to 8,000 mu.

Dongsheng Forest Park is marked on a map of Dongsheng District in Ordos.

The two sides also agreed that the Dongsheng District Government must let Wan Yu Jiaye (or designated enterprise) transfer the land at the cost price, and the transfer fee will be returned to Wanyu Jiaye within one month as land acquisition, park construction and other related expenses and advance income; Dongsheng District Government agrees that Wan Yu Jiaye will participate in the transformation of the old city and enjoy the same policies as the return of land transfer fees in the development of forest parks; Wan Yu Jiaye must participate in the bidding, auction and hanging of every land in the area organized by Dongsheng District. If no competitor bids and auctions the land at a higher price, Wan Yu Jiaye must transfer the land at the reserve price, and the auction money will be returned according to the above agreement; Dongsheng District Government shall not approve any unit or individual to acquire land and build within the planning scope of Forest Park, and resolutely stop any new construction project from appearing in Wanyu Jiaye Forest Park and the old city reconstruction area.

According to the documents, it was Han Guangyuan, the deputy head of Dongsheng District who was in charge of land at that time who signed and sealed the aforementioned development agreement and supplementary agreement. China News Weekly learned that in 2012, the Ministry of Land and Resources reported that Han Guangyuan had been severely punished by the discipline inspection and supervision organs of Ordos City because of his involvement in the illegal land acquisition by Dongsheng District Government. Soon after, Han Guangyuan left the post of deputy district head and worked as the dean and party secretary of a vocational and technical college. Now he has retired. On October 8, Han Guangyuan told China Newsweek that it was not up to him to decide whether to sign or seal the supplementary agreement. All decisions of the supplementary agreement were discussed at the relevant meeting of Dongsheng District Government, and he only implemented them.

The degree of freedom given by the Dongsheng District Government at the agreement level has facilitated what Hao Zhangang will do next.

There are frequent chaos in reselling land

In July 2019, a real estate company from Fujian (hereinafter referred to as "Company F") filed an arbitration with the Ordos Arbitration Commission because the other party failed to submit the land as agreed after purchasing it from Wan Yu Jiaye. The legal document of this arbitration event opened the corner of Hao Zhangang’s land reselling business.

In January 2010, the two parties signed an agreement that Wanyu Jiaye sold 650 mu of construction land in the Forest Park to Company F at a price of 1.5 million yuan per mu, totaling about 1 billion yuan, in the name of the first-class land development enterprise entrusted by the Ordos government, and ensured that Company F could divide the project into several plots according to the plan, and each piece of land could independently apply for a land use certificate; Company F won the land use right of the project plot with a "land payment" of no more than 1.5 million yuan per mu, including a land transfer fee of 350,000 yuan per mu handed over to the land management department, and the rest was paid to Wan Yu Jiaye at a price of 1.15 million yuan per mu.

After the signing of the agreement, Company F paid Wan Yu Jiaye the "land deposit" at the price of 1.15 million yuan per mu, and Wanyu Jiaye also promised that if the land transfer fee exceeded 350,000 yuan per mu in the bidding, auction and auction, Wanyu Jiaye would refund the excess.

Under the arrangement of Wanyu Jiaye, Company F participated in the land bidding, auction and hanging organized by Dongsheng District Natural Resources Bureau, and paid the land transfer fee at the price of 350,000 yuan per mu as agreed in the agreement.

However, Wanyu Jiaye was unable to provide land afterwards. The agreement between the two parties originally stipulated that Wan Yu Jiaye was responsible for land acquisition compensation, demolition and resettlement, three links and one leveling, and delivered the net land to Company F on August 1, 2010. However, Wanyu Jiaye failed to provide net land on time. The purchase of land cost 1 billion yuan, which led to the lack of funds for F company to carry out three links and one leveling, and the project was put on hold.

In the arbitration, Company F held that Wan Yu Jiaye illegally sold the right to use state-owned land, and the contract was invalid. Wanyu Jiaye advocates that the two parties are legally contracted. On October 23rd, 2020, the Ordos Arbitration Commission made an award and supported Wan Yu Jiaye’s claim. On October 9th, the person in charge of Company F told China Newsweek that the problem has not been solved so far and the company has withdrawn from Ordos market.

A person familiar with the local situation told China Newsweek that Ordos is a typical human society, just as financing in business is usually private lending among acquaintances. In the forest park project, disputes arise, and it is rare for F Company to choose judicial channels to solve them.

Before Hao Zhangang was arrested, Ordos Wanye Real Estate Development Co., Ltd. (hereinafter referred to as "Wanye Company") had been expecting that the dispute between it and Wan Yu Jiaye could be settled through coordination.

On June 11th, 2008, Wanye Company signed the Land Transfer Agreement with Wan Yu Jiaye, and Wanyu Jiaye transferred 74.46 mu of gross land located in the north of Textile Street in Dongsheng District, that is, the D-2 plot of Forest Park Project to Wanye Company, with a price of 500,000 yuan per mu, ensuring that the land use certificate and other related procedures will be handled to Wanye Company.

Shen Shan, the relevant person in charge of Wanye Company, told China Newsweek that the price of 500,000 yuan per mu was actually the lowered price after cooperation. At the beginning of the cooperation, Wan Yu Jiaye promised to transfer the land "three links and one leveling" to Wanye Company at a price of 3 million yuan per mu, and Wanye Company paid a deposit of 80 million yuan. Later, due to difficulties in demolition, Wan Yu Jiaye could not deliver the net land, and Wanyu Jiaye re-signed an agreement with Wanye Company to lower the land price to 500,000 yuan per mu.

Wanyu Jiaye’s land demolition is always not smooth. According to Shen Shan, the main reason is that the asking price of relocated households is getting higher and higher, and "enterprises can’t afford land acquisition compensation". Wu Tian, a retired official of the Land Acquisition Unit of Dongsheng District Land Bureau, also told China Newsweek that with the passage of time, the demolition of the forest park became more and more difficult, and about 1,000 mu of land was finally demolished, which only accounted for about 3% of the total area of the whole project.

In cooperation with Wanyu Jiaye, Shen Shan also found that on August 28th, 2008, Wan Yu Jiaye obtained the land certificate of plot D-2, and on the same day, Golden Eagle Wanjia also obtained a land certificate of plot D-2. Shen Shan recalled that after years of mediation by Jiaye and the government in Wan Yu, the D-2 plot was finally owned by Wanye Company, which spent about 200 million yuan on the project and finally started construction in 2020. Although construction started, there was another problem in the floor area ratio. Shen Shan introduced that when Wanyu Jiaye sold the land to Wanye Company, it agreed that the plot ratio was 4. Now the government department thinks that this is not in compliance with the regulations, and Wanye Company needs to pay about 30 million yuan to the government department for this purpose.

"Hao Zhangang told us that he could help us coordinate the floor area ratio problem. Now that he has been arrested, there is nothing we can do." Shen Shan said.

The "rich man" created by the forest park project

Wanye Company and F Company are not the only companies that buy forest park land from Wan Yu Jiaye. According to Shen Shan, about 20 companies have bought land from Wan Yu Jiaye, which makes Hao Zhangang’s business bigger and bigger.

On May 18th, 2010, Wan Yu Jiaye Urban Construction Investment Group Co., Ltd., actually controlled by Hao Zhangang, was established with a registered capital of 150 million yuan, with Hao Zhangang holding 95% of the shares and Zhang Zhicheng, the vice president, holding 5% of the shares. According to a publicity material, in 2011, the real estate development area of the Group was about 730,000 square meters, with 300,000 square meters completed and 1.4 billion yuan returned. This publicity material also mentions a "three-year plan": it is planned to develop an area of 1.5 million square meters by 2013 and increase the sales income to 7.5 billion yuan, "to build the company into a first-class real estate company in Inner Mongolia and even the whole country."

An employee of Golden Eagle Wanjia recalled that Wanyu Jiaye originally worked on the 10th floor of Tianyou Building in Dongsheng District, and around 2010, another Wan Yu Jiaye Building was built on Tuanjie Road in Dongsheng District as the group headquarters. A business owner who has been to Jiaye Building in Wan Yu told China Newsweek that what impressed him the most was the lobby on the first floor, with a high ceiling and golden decoration, which looked very luxurious. In Wan Yu Jiaye Building, the access to the office area of Wanjia Group upstairs is an independent elevator. If outsiders want to take the elevator to enter the office area, they need to be remotely controlled by the security personnel upstairs.

With the expansion of business, Hao Zhangang’s ambition is no longer satisfied with the corner of Ordos. Wan Yu Jiaye Urban Construction Investment Group is composed of six branches in Inner Mongolia, with a land reserve of 20,000 mu. Its industries are all over Wuhai, Bayannaoer and Hohhot, among which there are many large-scale projects such as five-star resort hotels, high-grade villas and high-rise residential quarters. An official from Erdos once visited the project of Wan Yu Jiaye in Linhe District of Bayannaoer City. He still remembers a bridge built by Wanyu Jiaye for Linhe District. "We were very surprised when we saw it. The bridge was so beautiful."

The official told China Newsweek that, like the forest park project in Erdos, this bridge in Bayannaoer City is also an infrastructure investment made by Hao Zhangang to win the corresponding construction land. "Hao Zhangang has never been stingy with urban construction in order to get the construction land smoothly." The official said.

Established in February 2001, Beijing Guoyao Wanwei Information Technology Co., Ltd. (hereinafter referred to as "Beijing Guoyao") is represented by Shi Baowei, nephew of Hao Zhangang, whose wife Meng Caixia holds 74% of the shares and the Institute of Remote Sensing Application of Chinese Academy of Sciences holds 11%. Chen Kai (pseudonym), who was the general manager of Beijing Guoyao from 2011 to 2013, told China Newsweek that Beijing Guoyao’s main business was remote sensing surveying and mapping. In those years, he often followed Hao Zhangang on business trips to Inner Mongolia and other central and western regions to talk about cooperation with local governments. As a technician, on the one hand, he was a "platform" for Hao Zhangang; On the other hand, we can also get land surveying and mapping projects from local governments.

Chen Kai said that because Hao Zhangang did not understand remote sensing technology, Beijing Guoyao was more like a real estate company. "But Hao Zhangang had a soft spot for science and technology. At that time, Hao Zhangang said that real estate had no future and should engage in science and technology."

Hao Zhangang’s "New Story of Science and Technology"

Probably since 2014, Hao Zhangang began to enter the technology industry in a big way.

The 2020 annual financial report of Shenyang Xinsong Robot Automation Co., Ltd. (hereinafter referred to as "Shenyang Xinsong") shows that Xinsong Robot Investment Co., Ltd. (hereinafter referred to as "Robot Investment Company") was established on April 17, 2014 by Shenyang Xinsong, Beijing Wan Yu Jiaye Real Estate Investment Co., Ltd. and Huacheng Xinlian (Beijing) Technology Co., Ltd., with a registered capital of 100 million yuan, of which Shenyang Xinsong agreed to contribute 37 million yuan.

Hao Zhangang is the president of robot investment company, and Qu Daokui, founder and president of Shenyang Xinsong, is the chairman of robot investment company. Robot investment company claims to be "excellent intelligent industry investment operator", and has raced around the country in the name of Shenyang Xinsong to build Xinsong robot industrial park.

Zhang Hai, an employee of Robot Investment Company, told China Newsweek that when robot investment companies ask for land from local governments, most of them are negotiated by Hao Zhangang. At present, the company has six industrial parks, which are located in Fuyang, Anhui, Xinxiang, Hunan, Xiangtan, Zhangjiajie, Yangzhou, Jiangsu and Shenyang, Liaoning. Because most of them are located in the suburbs of third-tier cities, the investment situation is not very satisfactory. Zhang Hai said that Hao Zhangang won the construction land through industrial park projects in various places and then resold it to others, such as the "blooming everywhere" model of Ordos Forest Park.

The net profit of robot investment company is very high. Shenyang Xinsong’s 2020 annual financial report shows that as of the end of the reporting period, the total assets of robot investment companies were about 1.72 billion yuan and the net profit was about 230 million yuan, an increase of about 103% compared with the same period of the previous year.

While working in a robot investment company, Zhang Hai said that he had never heard Hao Zhangang mention his past in Inner Mongolia, and his impression of Hao Zhangang was hard work. "We often say privately that his boss is still working so hard. If we had so much money, we would have gone to play." Zhang Hai said.

Hao Zhangang has a bed in the office of the robot investment company in Beijing. He basically doesn’t go home at ordinary times, and he eats and lives in the company. Zhang Hai recalled that even for the New Year, Hao Zhangang was in the office. "He doesn’t smoke or drink, which is not good for women. He lives frugally and eats in the canteen." Zhang Hai said.

The "victim boss" once complained everywhere.

On October 11th, China Newsweek learned from a person close to the police that the case of Hao Zhangang has entered the stage of review and prosecution. Among the 12 gang members arrested by the police, some of them have been released from criminal compulsory measures due to insufficient evidence. At present, the police are supplementing evidence in Beijing and Inner Mongolia.

According to Shen Shan, the person in charge of Wanye Company, the main reason why Hao Zhangang was arrested was the forest park project. In his view, the frequent rights protection of the "victim" boss who bought land in the project is the most direct reason why Hao Zhangang was arrested. In the process of cooperation with Hao Zhangang, many bosses encountered the situation that they could not be demolished and delivered. "Every time this happened, Hao Zhangang always said that he would help find a way. He dragged on for too long until we had nowhere to go and complained everywhere."

Shen Shan recalled that as early as the end of 2020, the audit department entrusted the audit firm to its company to understand the situation of the forest park project and collect evidence of Hao Zhangang’s illegal reselling of land. Dongsheng District Natural Resources Management Bureau cooperated very much and handed over all the documents of the Forest Park Project to the audit department. Shen Shan described that the papers piled up like hills. "At that time, they took away a lot of boxes." In the first half of 2021, investigators from Baotou Public Security Bureau asked him about the situation. "They lived in Ordos for a long time and found many victims to understand."

China News Weekly learned that Hao Zhangang’s arrest was not unrelated to the anti-corruption storm in Inner Mongolia in recent years. Chen Kai, who once worked in Beijing Guoyao, told China Newsweek that Wen Jianhua, the former deputy inspector of the Inner Mongolia Department of Land and Resources, who was investigated in 2018 on suspicion of corruption, bribery, bribery and illegal transfer of land use rights, had close contacts with Hao Zhangang. Wen Jianhua used to be the director of the Bureau of Land and Resources of Ordos City. During his tenure in the land department of Hohhot, he also had many contacts with Beijing Guoyao. "Wen Jianhua usually comes to Beijing, and Hao Zhangang receives it at the five-star hotel. I accompany him and the dining level is very high." Chen Kai recalled.

However, behind the arrest of Hao Zhangang, the beautiful blueprint of Ordos Forest Park project has remained on "paper". A planning document made by Dongsheng District Planning Bureau in September 2007 shows that the planning direction of Forest Park is to build an eco-garden city landmark attraction consisting of high-end residential areas, wildlife parks and grasslands in Inner Mongolia, which is considered to be the "ecological green lung" of Ordos.

On October 2nd, China Newsweek visited the Forest Park. It is located in the southeast of Ordos city, next to the urban area, and its north side is the bustling area of Dongsheng District. The reporter saw at the scene that several unknown roads surrounded the forest park. Most of the dense pines and cypresses on the ground of the park were less than one person high because of malnutrition. Some scattered farmers made a living by opening farmhouses, and some unfinished buildings stood alone in the cold wind. A faded "Forest Park" bus stop sign on the roadside seems to tell people that this project once existed.

　　The people of China, under the leadership of the Communist Party of China (CPC), have spent decades completing the industrialization process that developed countries have gone through for hundreds of years, creating a development miracle that attracts worldwide attention. The successful practice of Chinese-style modernization shows that the western modernization road is not the only way for mankind to modernize. The Chinese-style modernization road expands the way for developing countries to modernize and provides new choices for countries and nations in the world who want to accelerate their development and maintain their independence.

　　The establishment of the Communist Party of China (CPC) in 1921 was an epoch-making event. In the 100 years since the founding of the Communist Party of China (CPC), the people of China have been united and led to make remarkable achievements in promoting China’s socialist modernization through arduous exploration and continuous struggle. Today, our Party has led the people of China to embark on a new journey of building a socialist modern country in an all-round way.

　　The Communist Party of China (CPC) started China’s modernization journey at the time of national crisis.

　　China is an ancient civilization with a long history and splendid culture. It has been at the forefront of the world for a long time in history, and the hardworking, brave and intelligent people of China have made outstanding contributions to the progress of human civilization. After modern times, due to various reasons, China was trapped in poverty and weakness, and the Chinese nation was facing the crisis of national subjugation and extinction, which also made the people of China clearly aware of the backward situation in China, and thus began to seek reform, self-improvement and modernization.

　　In that era of aggression by western powers, incessant wars, social unrest and people’s displacement, in order to save the nation from peril and realize national rejuvenation, the people of China and countless people with lofty ideals made arduous explorations and epic struggles. Before the Revolution of 1911, the Taiping Heavenly Kingdom Movement, the Westernization Movement, the Reform Movement of 1898, the Boxer Rebellion and the New Deal in the late Qing Dynasty failed. Although the Revolution of 1911 ended the autocratic monarchy that ruled China for thousands of years, it failed to change the semi-colonial and semi-feudal social nature of China and the tragic fate of the people of China. After the Revolution of 1911, China tried various forms such as constitutional monarchy, parliamentary system, multi-party system and presidential system, and various political forces and their representatives appeared in succession, but failed to find the correct answer. The people of China still lived in misery and humiliation. Facts have proved that the self-improvement movement that does not touch the old social foundation, reformism in various names, the old peasant war, the democratic revolution led by the bourgeois revolutionaries, and various schemes that copy the western political system model can not complete the historical tasks of the Chinese nation to save the nation from extinction and resist imperialism and feudalism, nor can they stabilize the political situation and society in China, nor can they provide institutional guarantee for China to achieve national prosperity and people’s happiness.

　　During the period of poverty and weakness in China, various ideologies and thoughts were tried, but the capitalist road failed, and other "ideologies" failed to solve the future and destiny of China, let alone provide scientific theoretical guidance for China’s modernization. The October Revolution brought Marxism–Leninism to China and pointed out the direction for the rejuvenation of the Chinese nation and the modernization of China.

　　The Communist Party of China (CPC) stepped onto the historical stage at a critical moment when the Chinese nation was facing life and death. Since its establishment, the Communist Party of China (CPC) has been guided by Marxist scientific theory, taking communism as the highest ideal and ultimate goal, taking the happiness of the people of China and the rejuvenation of the Chinese nation as the initial heart and mission, and unswervingly striving for "China that pursues my ideal", leading the people of China to advance wave after wave and shed blood and sacrifice for national independence, people’s liberation, national prosperity and people’s happiness. Finally, the three mountains of imperialism, feudalism and bureaucratic capitalism were overthrown, and a new China was established, where the people were the masters of the country, which fundamentally changed the future and destiny of the people of China and the Chinese nation, irreversibly ended the tragic fate of China’s domestic troubles and foreign invasion after modern times, and started the great journey of China’s modernization.

　　Chinese modernization was formed in the process of continuous exploration by the Communist Party of China (CPC) people.

　　Different countries will choose different modernization paths because of their different historical culture, basic national conditions and historical missions. After the founding of New China, the Communist Party of China (CPC) led the people of China to continuously explore the road of Chinese modernization, made great achievements that attracted worldwide attention, created the miracle of rapid economic development and long-term social stability, and expanded the ways for developing countries to modernize.

　　Before the founding of New China, at the Second Plenary Session of the Seventh Central Committee of the Communist Party of China, Comrade Mao Zedong proposed to the whole party the historical task of "steadily transforming China from an agricultural country into an industrial country and building China into a great socialist country". Since the founding of New China, our Party has made arduous explorations in socialist modernization. Comrade Mao Zedong pointed out that our task "is to settle down so that we can build our country’s modern industry, modern agriculture, modern science and culture and modern national defense".

　　After the Third Plenary Session of the 11th CPC Central Committee, China’s socialist modernization entered a new historical period. Comrade Deng Xiaoping emphasized that whether modernization can be realized "determines the destiny of our country and nation" and "the modernization we are engaged in is Chinese-style modernization. The socialism we are building is socialism with China characteristics ". Under the leadership of the Communist Party of China (CPC), we have successfully embarked on the road of Chinese modernization. Based on China and facing the world, this modernization road insists on taking Marxism as the guidance, the Communist Party of China (CPC) as the highest political leading force, Socialism with Chinese characteristics road and people-centered, striving to build a prosperous, strong, democratic, civilized, harmonious and beautiful socialist modernization power, realize the great rejuvenation of the Chinese nation, strive to achieve common prosperity for all people, promote all-round development of people, and strive to promote world peace and development, which has distinctive characteristics of the times and China. This road to modernization not only conforms to the reality of China and embodies the laws of Socialism with Chinese characteristics’s construction, but also follows the trend of the times and embodies the laws of world modernization and the development of human society.

　　China’s modernization process is not smooth sailing, but under the strong leadership of the Communist Party of China (CPC) and the joint efforts of several generations of China people, China has gone from "lagging behind the times" to "catching up with the times" and then "leading the times", and the road of Chinese modernization has become wider and wider. China has moved from poverty to prosperity, becoming the second largest economy in the world, and its economic strength, scientific and technological strength and comprehensive national strength have greatly jumped; The people’s life in China has moved from insufficient food and clothing to a well-off society in an all-round way, and the happiness index has been continuously improved; China has developed from a traditional agricultural country to an industrial country, and its degree of industrialization is getting higher and higher, making it the largest manufacturing country; China has moved from closed and semi-closed to all-round opening, deeply participated in economic globalization and made more and more contributions to human civilization; China is getting closer to the center of the world stage, and its international influence has increased significantly.

　　The people of China, under the leadership of the Communist Party of China (CPC), have spent decades completing the industrialization process that developed countries have gone through for hundreds of years, creating a development miracle that attracts worldwide attention. The successful practice of Chinese-style modernization shows that the western modernization road is not the only way for mankind to modernize. The Chinese-style modernization road expands the way for developing countries to modernize and provides new choices for countries and nations in the world who want to accelerate their development and maintain their independence.

　　To build a socialist modern country in an all-round way, we must uphold and strengthen the overall leadership of the party.

　　The 19th National Congress of the Communist Party of China made a strategic arrangement to advance the goal of the second century in two stages, that is, to basically realize socialist modernization by 2035 and to build China into a strong, prosperous, democratic, civilized, harmonious and beautiful socialist modernization country by the middle of this century. Based on the reality of the new development stage, the Fifth Plenary Session of the 19th CPC Central Committee put forward the long-term goal of basically realizing socialist modernization by 2035. To build a socialist modern country in an all-round way, we must uphold and strengthen the overall leadership of the party.

　　The modernization to be realized in China is the modernization with a huge population, the common prosperity of all the people, the coordination of material civilization and spiritual civilization, the harmonious coexistence of man and nature and the modernization of peaceful development. Realizing such modernization is the common aspiration of all Chinese people, and it is also the ideal and pursuit, responsibility and responsibility of the Communist Party of China (CPC) people. To realize such modernization, we must have a "backbone" and a strong leadership core. In contemporary China, this core can only be the Communist Party of China (CPC) as the highest political leading force. General Secretary of the Supreme Leader stressed: "History has proved and will continue to prove that without the Communist Party of China (CPC)’s leadership, national rejuvenation must be a pipe dream." Therefore, to build a socialist modern country in an all-round way, we must uphold and strengthen the overall leadership of the Party, strengthen the "four consciousnesses", strengthen the "four self-confidences" and achieve the "two maintenance".

　　To uphold and strengthen the overall leadership of the party, we must comprehensively promote the new great project of party building. At present and in the future, China’s development is still in an important period of strategic opportunities, but there are new developments and changes in both opportunities and challenges, and the domestic and international environment facing China is undergoing extensive and profound changes. Although China has unique political advantages, institutional advantages, development advantages and opportunity advantages, and there are many favorable conditions for building a socialist modern country in an all-round way, the problem of insufficient development imbalance is still outstanding, the historical task to be completed in promoting modernization is still very arduous, and the contradictions, difficulties and risks faced in reform, development and stability are still very complicated, which puts new demands on the party’s ruling ability and leadership level. At present, party building is still facing a series of new situations, new problems and new challenges. It is more arduous and urgent than ever to implement the task of managing the party in an all-round way. To ensure that the Party is always in the forefront of the times in the historical process of profound changes in the world situation, always the backbone of the people of the whole country in the historical process of coping with various risks and tests at home and abroad, and always the core of strong leadership in the historical process of upholding and developing Socialism with Chinese characteristics, we must strengthen Party building with the spirit of self-revolution, and constantly enhance the Party’s ability of self-purification, self-improvement, self-innovation and self-improvement.

　　On the occasion of celebrating the centenary of the founding of the Communist Party of China (CPC), we need to take into account the overall situation of the great rejuvenation strategy of the Chinese nation and the unprecedented changes in the world in the past century, conscientiously sum up the Communist Party of China (CPC)’s valuable experience in leading Chinese modernization, raise it to a theoretical height, and constantly enrich the treasure house of Marxist modernization theory; Unswervingly promote modernization, promote the great rejuvenation of the Chinese nation with Chinese modernization, constantly make new and greater contributions to mankind, and fully demonstrate the characteristics and advantages of Chinese modernization. Standing at the key node of the historical intersection of the goals of "two hundred years", we should constantly improve our political judgment, political understanding and political execution, and constantly improve our political ability, strategic vision and professional level to grasp the new development stage, implement the new development concept and build a new development pattern, so as to ensure that socialist modernization will be basically realized by 2035 and China will be built into a strong, prosperous, democratic, civilized, harmonious and beautiful socialist modernization country by the middle of this century.
