Sheng Xiujie, Chief Physician of Gynecology, Third Affiliated Hospital of Guangzhou Medical University

　 　 Gynecological tumor:

　　It is best to prevent and treat early surgery, chemotherapy and radiotherapy, and it is "three axes"

　　Surgery, chemotherapy and radiotherapy are still the main treatment methods for gynecological tumors, and other treatment methods are only used as auxiliary supplementary treatment methods to improve the curative effect with surgery, radiotherapy and chemotherapy.

　　Sheng xiujie　

　　Chief Physician of Gynecology, Third Affiliated Hospital of Guangzhou Medical University

　　Gynecological tumors mainly include vulvar tumors, vaginal tumors, uterine tumors, ovarian tumors and tubal tumors, among which uterine and ovarian tumors are more common. Professor Sheng Xiujie, director of gynecology department of the Third Affiliated Hospital of Guangzhou Medical College, said that the infection of human papillomavirus (HPV) has a certain relationship with cervical cancer, but the causes of other gynecological tumors are not clear, which may be related to factors such as heredity, environment, infection and immunity.

　　At present, there are many treatments for tumors. There are surgery, chemotherapy, radiotherapy, biotherapy and immunotherapy. However, at present, surgery, chemotherapy and radiotherapy are still the main treatment methods for gynecological tumors, and other treatment methods are only used as auxiliary supplementary treatment methods to improve the curative effect with surgery, radiotherapy and chemotherapy.

　　Sheng Xiujie reminded that the best way to deal with gynecological tumors is early prevention and treatment. Through pelvic examination and various auxiliary examinations, you can basically judge whether you have gynecological tumors.

　　Sheng Xiujie also pointed out that cervical cancer is the only cancer that can be clearly identified and prevented. To prevent cervical cancer, it is very important to screen cervical intraepithelial lesions, and this kind of screening needs to follow three steps of screening process:

　　Step one: cytology +HPV detection

　　Cervical cytological examination is the most basic method for screening cervical lesions, commonly known as "cervical curettage", commonly called TCT, CCT or LCT, etc. A brush is used to brush cells on the cervix, and thin-layer smear and computer-aided detection are used to detect "bad" cells at an early stage.

　　HPV detection, similar to the process of cytological examination, also uses a brush to obtain samples such as cervical tissues and secretions to detect whether HPV is carried. It can be used alone or combined with cytological examination as a primary screening method for cervical lesions.

　　Step 2: colposcopy

　　Colposcopy is suitable for cytological examination when abnormal cells are found, and further colposcopy should be done to make a definite diagnosis. This examination uses a special camera lens to observe and evaluate the cervical lesions, and can make a fixed-point biopsy of suspicious tissues of the cervix under the instruction of the lens to improve the accuracy of finding lesions.

　　Step 3: Histopathological examination

　　Including cervical biopsy and cervical conization, is a reliable method to diagnose cervical lesions. General lesions can be biopsied at single or multiple points under the guidance of naked eyes or colposcopy. However, for the lesions whose boundaries can’t be seen by colposcopy, the lesions are deeper than the cervical canal, and the biopsy is high-grade lesions (HSIL), diagnostic cervical conization is needed to confirm the diagnosis.　

Wang Bailin, Director of General Surgery and Director of Hepatobiliary Surgery, Guangzhou Red Cross Hospital

　　Liver cancer:

　　Early diagnosis is difficult, and the curative effect is not good in the middle and late stage.

　　It is best for patients with liver cancer to choose specialized consultation and treatment in large hospitals; Don’t blindly believe the advertisements and propaganda of informal medical institutions, so as not to delay the illness and delay the treatment; Be careful when searching hospitals online, so as not to be fooled.

　　Wang Bailin　　

　　Director of General Surgery, Director of Hepatobiliary Surgery, Guangzhou Red Cross Hospital

　　Liver cancer is one of the most common malignant tumors in China. It is difficult to diagnose in the early stage, and the treatment effect in the middle and late stage is not ideal. It is easy to relapse and metastasize, and the mortality rate is relatively high. Wang Bailin, director of general surgery and director of hepatobiliary surgery in Guangzhou Red Cross Hospital, said that the number of patients with viral hepatitis such as hepatitis B and hepatitis C in China is very large, and the number of hepatitis B virus carriers alone is close to 100 million, while "hepatitis-cirrhosis-liver cancer" will be transformed in a certain proportion, which is the "trilogy" of liver cancer, so there are many patients with liver cancer in China. Many patients with liver cancer don’t have obvious early symptoms and signs, and they don’t go to see a doctor until they have typical symptoms and signs. Their liver cancer has developed to the middle and late stage, and they have lost the opportunity of radical surgery and the outcome is relatively poor.

　　The treatment of liver cancer is a comprehensive treatment based on surgery. Wang Bailin said that surgery is the best treatment method, and it can also be combined with interventional therapy, radiofrequency ablation therapy, cryotherapy and microwave therapy. In recent years, patients with advanced liver cancer can choose targeted drug therapy if economic conditions permit, but the overall effective rate is less than 20%; If you can find a liver donor, you can also have a liver transplant.

　　Wang Bailin suggested that patients with liver cancer had better choose specialized consultation and treatment in large hospitals; Don’t blindly believe the advertisements and propaganda of informal medical institutions, so as not to delay the illness and delay the treatment; Be careful when searching hospitals online, so as not to be fooled.

Luo Rongcheng Dean, Hospital of Integrated Traditional Chinese and Western Medicine, Southern Medical University

　　Lymphoma:

　　Biochemotherapy is the first choice, and the toxic and side effects of new drugs are reduced.

　　Compared with most solid tumors, the therapeutic effect of lymphoma is relatively good, especially in the clinical application of immunotherapy. The overall 5-year survival rate of diffuse large B-type lymphoma is over 60%.

　　Luorongcheng　　

　　Dean of Southern Medical University Hospital of Integrated Traditional Chinese and Western Medicine

　　It is reported that lymphoma is one of the fastest growing malignant tumors in the world. Among them, the incidence of lymphoma in China is increasing at a rate of 5% per year, and there are about 84,000 new lymphoma patients and more than 47,000 deaths each year. Faced with such a severe situation, it is urgent to promote standardized and individualized treatment of lymphoma. Lymphoma is a malignant tumor originating from the lymphatic system, which is mainly divided into Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). Non-Hodgkin’s lymphoma is more common in China patients, accounting for more than 80% of lymphoma.

　　"In fact, compared with most solid tumors, the treatment effect of lymphoma is still relatively good, especially in the clinical application of immunotherapy. The overall 5-year survival rate of diffuse large B-type lymphoma is over 60%." Professor Luo Rongcheng, dean of the Hospital of Integrated Traditional Chinese and Western Medicine of Southern Medical University and director of the Cancer Center of Southern Medical University, said that this benefited from the development of biotherapy technology, which enabled lymphoma to continue to adhere to cellular immunotherapy within five years after remission, and patients could get better results.

　　For example, Luo Rongcheng once treated a 16-year-old young Wang. When Wang graduated from high school, he suddenly had a stomachache. When he was sent to hospital, he found that a 20 cm tumor in the pelvic cavity caused intestinal obstruction. After biopsy, he was diagnosed with advanced diffuse large B-cell lymphoma. Fortunately, after eight times of biological chemotherapy, his symptoms were completely relieved and he escaped. For the next four years, he continued to receive cellular immunotherapy and was followed up for seven years. He has finished his college studies and now he has joined the work.

　　According to reports, the treatment methods of lymphoma mainly include immunotherapy, chemotherapy, radiotherapy and hematopoietic stem cell transplantation. The classification of lymphoma by the World Health Organization clearly points out that each pathological type of lymphoma is an independent disease, and the treatment adopted is also different. The patient must decide the treatment strategy according to the condition after a comprehensive examination.

　　At present, most lymphoma patients still prefer chemotherapy. Some patients combined with immune targeted therapy can significantly improve the effective rate and improve the survival time. Surgery is not the main treatment, but in a few cases, it can be considered. A large number of clinical research data show that 50%~60% of patients with early lymphoma are expected to be cured by using immunotherapy represented by monoclonal antibody rituximab in initial treatment.

　　The toxic and side effects brought by traditional chemotherapy often worry many patients. Luo Rongcheng said that the emergence of new chemotherapy drugs has significantly reduced the toxic and side effects. In addition, common toxic and side effects have mitigation strategies, so patients don’t need to worry too much. However, it should be reminded that if patients have a fever during chemotherapy, they must go to the hospital for a follow-up visit and don’t take it lightly. At present, according to the latest molecular classification, lymphoma can be divided into more than 100 types, and different types of lymphoma have different therapeutic effects. In general, Hodgkin’s lymphoma accounts for 9%~10% of lymphoma, which is a group of malignant lymphoma with relatively good curative effect. Non-Hodgkin’s lymphoma accounts for about 90% of all lymphoma cases. The classification is complex and the prognosis depends on the situation.

Wang Shunqing Director, Department of Hematology, Guangzhou First People’s Hospital

　　Hematological neoplasms:

　　The overall survival rate can reach 95%, and regular doctors will not "guarantee"

　　"Today, the cure rate and survival rate of blood tumors have been greatly improved, and some types of leukemia are completely curable."

　　Wang shunqing　　

　　Director, Department of Hematology, Guangzhou First People’s Hospital

　　When it comes to blood tumors, many people’s understanding still stays in the impression of the Japanese drama "Blood Suspicion", equating leukemia with terminal illness. "Twenty years ago, it was true that many leukemia patients had only two to three years between diagnosis and death. But today, the cure rate and survival rate of blood tumors have been greatly improved, and some types of leukemia are completely curable. " Professor Wang Shunqing, director of the Department of Hematology, Guangzhou First People’s Hospital, said in an interview.

　　Wang Shunqing told reporters that leukemia is divided into many types, quite a few of which have good therapeutic effects, and some of which are more difficult and easy to relapse.

　　"Take the most common childhood acute lymphoblastic leukemia in recent years as an example. This kind of leukemia is divided into’ standard risk type’ and’ high risk type’, among which’ standard risk’ patients account for the majority. More than 85% of patients with’ standard risk’ can be cured if they adopt a standardized chemotherapy plan. "

　　In addition, the cure rate of adult acute promyelocytic leukemia can reach 80%~90% through chemotherapy and drug treatment. There is also chronic myeloid leukemia. "This kind of leukemia is treated like chronic diseases such as hypertension and diabetes because of the targeted drugs with very significant effects. As long as patients take drugs for life, their condition can be controlled. At present, this targeted drug has been produced in China, the cost is not too high, and medical insurance can be reimbursed. " Wang Shunqing said.

　　As for those leukemia that are more difficult to treat, Wang Shunqing believes that the treatment effect has also been significantly improved compared with the past. "These leukemias can usually be treated by bone marrow transplantation or hematopoietic stem cell transplantation. These two technologies are very mature at present. Moreover, with the development of technology, the problem of matching between doctors and their families, which used to be difficult, has now been well solved. " For example, there is now a haploid transplantation technology, even if the donor bone marrow or stem cells are not completely matched with the patient, transplantation can be performed.

　　"So, the overall survival rate of leukemia patients can reach more than 95%." Wang Shunqing said. However, the treatment effect and the survival rate of patients are definitely based on the standardized treatment plan.

　　In addition, more and more attention is paid to precise treatment of leukemia, and some types have reached the genetic level. "So some leukemias need to do more tests before starting treatment, in order to have accurate guidance on the treatment plan and predict the prognosis." Wang Shunqing said, but sometimes patients don’t understand. On the one hand, they feel that so many tests are too much for the economy, and on the other hand, some patients have misunderstandings or distrust of doctors. "Because in a regular hospital, it must be very objective for doctors and patients to talk about treatment, and doctors will never assure patients that’ how much you spend on this disease, we will definitely cure you’. On the contrary, it is precisely because of the uncertainty of medicine that many factors will affect the treatment process, so the doctor will tell the patient the risks and benefits in the treatment process completely, and then analyze with the patient which scheme is the most favorable. "

　　Combined with his many years of medical experience, Wang Shunqing suggested that the majority of patients, unfortunately diagnosed with tumors, should not despair at first, because with the development of medicine today, the treatment effect of many tumors is much better than before. Secondly, you must consult a specialist in a regular hospital, and don’t blindly believe in advertisements, remedies, etc., especially those "magic doctors" who clap their chests and say that they will definitely cure the tumor.

Wang Cunchuan, Vice President and Director of Gastrointestinal Surgery, First Affiliated Hospital of Jinan University

　　Gastrointestinal neoplasms:

　　Ask more doctors about the unrecognized new treatment.

　　Radical resection of gastrointestinal tumors should be considered first. Some new treatments, such as cell biotherapy, are still in the clinical experimental stage, and their efficacy has not been recognized. It is recommended to know more and ask more doctors before choosing.

　　Wang cunchuan　　

　　Vice President and Director of Gastrointestinal Surgery, First Affiliated Hospital of Jinan University

　　Gastrointestinal tumors are very common, such as colorectal tumors, and some of them can be prevented. Professor Wang Cunchuan, deputy dean of the First Affiliated Hospital of Jinan University and director of gastrointestinal surgery, said that 75% of colorectal tumors are gradually developed from polyps, which can be found and removed by colonoscopy, which is the best prevention. If you have gastrointestinal tumors, you should first consider radical resection, and now do more minimally invasive surgery, and then combine chemotherapy and radiotherapy.

　　Some new treatments, such as cell biotherapy, are still in the clinical experimental stage, and their efficacy has not been recognized. However, some privately contracted and profit-oriented medical institutions sometimes exaggerate their efficacy, which may delay patients’ illness and may cause economic losses. It is recommended to know more before choosing, such as asking more doctors.

　　Wang Cunchuan said that at present, public top three hospitals, especially the affiliated hospitals of universities, generally have a good diagnosis and treatment system, a perfect multidisciplinary consultation system and complete equipment. Their medical staff are often exposed to cutting-edge medical expertise and have more experience in the treatment of tumor diseases. If you do four-level surgery such as radical resection of gastrointestinal tumors, it is more secure to go to these hospitals. Some private specialized hospitals and community hospitals have different levels of supporting software and hardware, which is not a big problem in dealing with common diseases, but not necessarily for radical surgical treatment of tumors. Patients are advised to choose carefully and learn more about the qualifications of medical institutions and doctors. Searching for information about seeking medical advice on the Internet, he suggested logging on to the official website of public hospitals, and it is best to go directly to the hospital to see a doctor for on-site consultation, while websites with competitive ranking, commercial promotion or lack of certification are likely to cause information asymmetry, or confusion and misleading.

Director, Cancer Center, First Affiliated Hospital, Guangzhou University of Chinese Medicine, Lin Lizhu

　　Treatment of tumor with combination of traditional Chinese and western medicine;

　　Eat Chinese medicine after seeing western medicine? It’s not that simple

　　After receiving the treatment of modern medicine, cancer patients should not blindly prescribe Chinese medicine by looking for "Chinese medicine practitioners" who do not know the source. They must use drugs in a dialectical way under the guidance of Chinese medicine practitioners with experience in oncology, combined with the needs of the course of disease.

　　Lin Lizhu　　

　　Director of Cancer Center of the First Affiliated Hospital of Guangzhou University of Chinese Medicine

　　What should relatives and friends do if they find out about cancer? What factors should be considered when choosing a treatment plan?

　　Professor Lin Lizhu, director of the Cancer Center of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, said that there are many treatments for cancer. Taking the primary liver cancer with high incidence as an example, early surgical resection is the best treatment. If the patients in the middle and late stages are not suitable for surgery after diagnosis, they should consider intervention, radiotherapy and chemotherapy and even targeted drug treatment according to the specific situation. However, most patients with liver cancer have suffered from hepatitis B and cirrhosis. Whether it is surgery, radiotherapy and chemotherapy or targeted therapy, the treatment has its own limitations, and preventing recurrence is still a difficult problem that has to be considered. Therefore, multidisciplinary and standardized comprehensive treatment has become the consensus of the medical community.

　　"Our research found that Chinese medicine combined with modern medicine can play different roles for patients with various cancers at different stages." Lin Lizhu revealed that a 7-year-old collaboration group of state administration of traditional chinese medicine’s "Eleventh Five-Year Plan" key specialty liver cancer, led by the First Affiliated Hospital of Guangzhou University of Chinese Medicine, verified that the results of a multi-center retrospective cohort study in 15 hospitals in the United Nations showed that Chinese medicine played a synergistic and attenuated role in the minimally invasive treatment and systematic treatment of liver cancer. Some traditional Chinese medicines can affect the DNA synthesis of hepatocellular carcinoma cells and inhibit their proliferation. In addition, Chinese medicine combined with interventional therapy can reduce liver function damage, protect residual liver function, and even make some large liver cancer that cannot be intervened become interventional, thus improving the curative effect of liver cancer and the quality of life of patients and prolonging the survival period.

　　"But unfortunately, many people don’t understand the combination of Chinese and Western medicine, thinking that after reading western medicine, they can eat some Chinese medicine." Lin Lizhu said with emotion. There are still many cancer patients who regard Chinese medicine as the last treatment for cancer, and they only come to Chinese medicine when various means such as surgery, radiotherapy and chemotherapy are exhausted. This is a misunderstanding. She explained that Chinese medicine emphasizes the treatment based on syndrome differentiation and the concept of "holistic" treatment, which can complement and complement each other with modern medicine (western medicine) such as surgery, radiotherapy and chemotherapy for "local" lesions. Still taking the treatment of liver cancer as an example, the 5-year recurrence rate is still as high as 50% after surgical resection of the focus in early patients. Strengthening spleen and protecting liver with Chinese medicine immediately after operation can improve the immunity of patients, promote the recovery of viscera function and reduce the recurrence rate; For patients with liver cancer in the stage of radiotherapy and chemotherapy, combined with traditional Chinese medicine treatment can reduce the side effects of drugs, reduce the damage to patients’ liver function, and help improve their quality of life and survival.

　　"However, the treatment of tumors with integrated traditional Chinese and western medicine is also a highly professional subject, which requires doctors to understand the knowledge of standardized treatment of tumors in modern medicine and must also have experience in treating tumors in traditional Chinese medicine." Lin Lizhu reminded that after receiving the treatment of modern medicine, cancer patients should not blindly prescribe Chinese medicine from unknown "Chinese medicine practitioners", but must be guided by Chinese medicine practitioners with experience in oncology, combined with the course of the disease.

With the rapid development of intelligent driving technology today, Equation Leopard 8 Intelligent Driving Edition has become an intelligent benchmark in the field of hard-core off-road SUVs with its Huawei Gankun Intelligent Driving ADS 3.0 system and a series of innovative "brain-controlled" black technologies. This model not only redefines the intelligent boundary of off-road vehicles, but also allows drivers to experience unprecedented technological charm.

Huawei ADS 3.0: end-to-end intelligent driving, opening a new era of the whole scene

The most striking thing about Leopard 8 Intelligent Driving Edition is its Huawei Gankun Intelligent Driving ADS 3.0 system. As the world’s first high-level intelligent driving system with end-to-end architecture, ADS 3.0 completely breaks the dependence of traditional intelligent driving systems on high-precision maps and realizes the whole scene from parking spaces to parking spaces. Whether it’s urban congested road sections, expressways or complex off-road scenes, ADS 3.0 can realize intelligent lane change, intelligent obstacle avoidance, intelligent speed regulation and other functions through laser radar and visual fusion sensing technology, making driving easier and safer.

In the parking scene, ADS 3.0 also showed great strength. ADS 3.0 can easily cope with parking in extremely narrow parking spaces, parking at the front of the car, parking at the rear of the car, and even parking without parking lines. What’s even more amazing about Songyuan Snacks is that its parking and driving function supports parking away from the car. The driver only needs to get off the bus, and the car can automatically complete the parking operation, which truly realizes the convenient experience of "getting off and leaving".

Yunnian -P hydraulic suspension: intelligent preview, off-road riding on the ground.

In addition to the powerful intelligent driving system, the Leopard 8 Intelligent Driving Edition is also equipped with the Yunqi -P intelligent hydraulic body control system of the same model as Looking Up at U8. This system integrates three core technologies: mechanical, hydraulic and electronic control. Huizhou Snacks has three major functions, including the maximum suspension stroke height of 140mm, three-level stiffness and intelligent damping, as well as two major capabilities: active preview and four-wheel linkage. In the off-road scene, Yunqi -P system can sense the road conditions in real time, automatically adjust the suspension height and stiffness, and ensure that the vehicle always maintains the best driving state.

What’s more worth mentioning is that the Leopard 8 version is also equipped with a "violence mode". This mode can accurately identify the ground slip rate and carry out adaptive control by carrying the road surface identification technology. Within 200 milliseconds, the power can be output to the wheel end, and the peak torque output time is less than 2 km/h, thus significantly improving the performance of the motor in low-speed off-road. Whether it’s a 100% 45-degree forward climb or a 70% 35-degree reverse climb, Leopard 8 Zhijia Edition can easily cope with it, even on the complex terrain such as Sanlianpo and Shalingtou in online celebrity.

Lingyuan Vehicle-mounted UAV: Aerial perspective, unlocking new off-road gameplay.

Leopard-8 Intelligent Driving Edition is also equipped with the "Lingyuan Vehicle-mounted UAV System" jointly built with DJI. The roof comes with a smart apron, and the drone can take off and land dynamically, automatically follow the shot, and generate a travel blockbuster with one click. Whether it’s a family trip to record the scenery or a professional off-road survey of the terrain, the car can be transformed into an "aerial photographer" and unlock the nine scenes. Through the car system, drivers can also view the pictures taken by drones in real time and plan the best off-road route, making off-road travel more intelligent and interesting.

Intelligent cockpit: AI empowerment to create a top driving experience

In terms of smart cockpit, Leopard 8 Smart Driving Edition also spares no effort. The new car adopts BYD 9000 chip with 4nm advanced process, which integrates the intelligent voice and intelligent image of AI model, providing drivers with a smooth and intelligent interactive experience. Through the "Fanghua" handcart interconnection function, drivers can also extend the applications and services on Huawei mobile phones to Qingyang escort in the car, realizing information sharing and interoperability. In addition, the Leopard 8 Smart Driving Edition is also equipped with luxury configurations such as 128-color ambient lights and 18-speaker Divare audio, which makes the driving experience more comfortable and enjoyable.

Safety performance: all-round protection, guarding every trip.

In terms of safety performance, Leopard 8 Smart Driving Edition also performed well. Its non-loaded body +CTC battery integrated design, the impact resistance is 10 times higher than the industry standard. The 14 airbags and infrared night vision system of the whole vehicle cover 300 meters of detection, and with Huawei’s omni-directional anti-collision technology, risks can be predicted in advance in rainy and foggy days. Whether in urban roads or off-road scenes, Leopard 8 Smart Driving Edition can provide all-round safety protection for drivers and passengers.

Special feature of 1905 film network "I have been an actor for more than 30 years, and I will look back for ten years. With the development of the country and society, I have experienced magnificent historical changes in the 21st century. From the 40 s to the 50 s, this is the most glorious decade for an actor. I don’t think it has been white. "

In recent years, he has successively appeared in films and other works. He said that if you can bring a touch and gain to the audience through your role, that is the best response.

"Keeping the island is keeping the country, and keeping the country is keeping the home." Zhang Hua, who "read" The Islander, was particularly impressed by this line. Looking at the moment when the "island keeper" guards the national flag every day, she suddenly feels a warm current in her heart. With the ups and downs of the plot in the play, she cried and laughed, laughing and crying.

Zhang Hua is a special blind movie fan. Since he was blind for more than ten years, he has been supporting his life by movies. She is one of the most active audiences in the cinema for the blind. Whether it is a new film or an old one, it is her "good heart." In her view, the film is a tool for her to communicate with the outside world, and it is also a gift to accompany her through the rest of her life.

Movies, sharing a better life. The film channel specially launched a series of documentary reports on "This Decade, Our Film Life". In this programme, we will talk to actor Hou Yong and visually impaired Zhang Hua, and feel their pursuit and love for the art of light and shadow.

Actor Hou Yong: I haven’t lived in vain for ten years.

Unlike many peers who love movies and become actors, Hou Yong was an actor first, and then fell in love with movies.

He was originally a drama actor. His first contact with the film was in 1988. As an extra actor, he was responsible for yangko dancing in Red and White. "Maybe my body language expression ability is slightly stronger. I was arranged to stand in front, and there were hundreds of people behind me." Hou Yong still remembers that it was a big scene, unlike multiple camera now, when there was a camera, and they were very excited when they saw the camera.

Because of this experience, he was always in awe of the camera, so that later, no matter whether he played a small role or a leading role, as long as he stood in front of the camera, he felt extremely lofty and sacred.

Having served in the army for 27 years, Hou Yong is often invited to create some positive roles.

Henry Hui Wang, a special soldier in "General Chen Geng", Chen Geng, a patriotic warrior in "General", Tang Shaoyi, a political activist in "Heroes of Fire", Wu Chenguang, the commander in chief, and Wang Changjie, the minister of the People’s Armed Forces in "The Islander" … Through light and shadow, he left a lot of roles that were deeply rooted in the hearts of the audience.

The Islander pushed Hou Yong’s acting career to a new peak. With the role of "Wang Changjie" in the film, Hou Yong was awarded the Best Supporting Actor in the 36th Popular Film Hundred Flowers Award.

The film is based on the story of Wang Jicai, former director of Kaishan Island militia post in Guanyun County, Jiangsu Province, and his wife Wang Shihua. Hou Yong revealed that he was the only one in the whole cast who had really seen Wang Jicai.

He and Wang Jicai are both from Jiangsu. One year, Lianyungang moral model presented an award, and he was lucky enough to know this moral model as an awarding guest. Unfortunately, not every few years, Wang Jicai died from overwork. Later, the script of Island Keeper was handed to Hou Yong, who accepted it without hesitation.

"Chang-jie wang and Jude Wong have deep brotherhood. He not only has the guilt of "fooling" Wang Jicai to the island, but also feels very practical because of Wang Jicai’s persistence on the island. This is a very complicated role. " In Hou Yong’s view, "Wang Changjie" is not the protagonist, but assists the protagonist to complete the role orientation of drama expression, and has been conveying the belief of feelings for home and country to Wang Jicai. "It is a little difficult to play". In the role-building, he emphasizes to render and express the emotion between them through lines, dialogues, modeling and lens.

He was able to win another award for "The Islander", and he bluntly said that this is a gratifying thing. "Most of the award-winning actors are lucky, but the premise of being lucky is that they must work hard. The result of hard work may be recognized, and it may be submerged. I have been fortunate enough to have had several times and I feel very gratified. "

In recent years, the film and television industry in China has developed rapidly. Styles and themes are more diverse, and a hundred flowers blossom. Hou Yong said frankly that this is a very good era, and literary and artistic works are powerful. In order to adapt to the development of the times, while deeply cultivating the performances of positive characters, he also devoted himself to trying different types of roles and striving to "jump out of the comfort zone".

"I feel a sense of honor to be called out by the audience."

Hou Yong is particularly concerned about the audience’s evaluation of his role. He hopes that his role can bring some positive effects to others. A few days ago, at a friend’s party, a demobilized soldier sighed to him, "Mr. Hou, it was when I saw your movie that I was inspired to become a soldier." I have watched your movie many times in XinBingLian. "

At that moment, Hou Yong was particularly moved, moved his film career, and could influence the audience more or less.

Hou Yong is 55 years old. He always tells himself that every time he shoots a play, he shoots one less. What he always insists on is to perform every scene well and shoot every work well. I hope that no matter whether it is three or five years or even ten years later, I will be worthy of my heart and myself.

Zhang Hua, a blind movie fan: I love movies and will never change in my life.

"We always say that the eyes are the windows of the soul. Movies are the eyes in my life and the only way for me to talk to the world."

In 2007, Zhang Hua, who had been nearsighted for a long time, suddenly went completely blind. At that time, she was 52 years old and cried for several days because her eyes were broken. She felt that there was no hope in life and once had the idea of giving up. It was not until a friend introduced her that she began to get in touch with movies, and she regained her thoughts of life.

After blindness, Zhang Hua has always been a loyal audience of the cinema. It is reported that the Mind Cinema is specially designed for the visually impaired, and volunteers will provide them with professional film explanations. The cinema has moved from place to place several times, but no matter whether it can only sit in the small courtyard at first or sit comfortably on the sofa chair now, as long as it is not sick and hospitalized, Zhang Hua will appear in the cinema on time every week, sit in the front row and concentrate on "watching movies".

Over the years, she has seen "The Islander" and remembered the model mind that "defending the island is defending the country, and defending the country is defending the home". She has seen it, and she is really moved by the volunteers who fought bravely in the ice and snow to resist US aggression and aid Korea.

Zhang Hua said with a smile that when she was young, her eyes were good, but she didn’t have time to watch movies. Now that I can’t see, I find that I haven’t seen many movies. She will spend the rest of her life making up all the good movies she has left behind.

"The glory of the golden hall may be the dream of countless Cai-ling wang. It was a dream like a bubble that made him brave to face everything … "

"A man appeared on the screen. He looked at the distance with a telescope in the storm. He was Wang Jicai, the island keeper. In the sun, the figure of the island keeper disappeared, and his wife cried … "

Although invisible to the eyes, Zhang Hua can still imagine vivid pictures and wonderful plots under the vivid interpretation of volunteers. During these days of blindness, she can’t see the mountains and rivers with her own eyes again, but movies are like her eyes, which bring her to feel the prosperity of the world and the brilliance of human nature.

In many excellent movies, she not only got a pleasant viewing experience, but also gained a belief that supports her life. For example, the hero models in some plays are also blind, but they still stubbornly live and never give up easily. This also makes Zhang Hua understand that there is always hope in life.

For more than ten years, movies have almost become the only source of Zhang Hua’s spiritual life, entertainment life and communication with the outside world. In her words, the film broadened her horizons, increased her knowledge and changed her life.

Today, the film industry in China has developed for a hundred years. In the twilight of her life, she was lucky enough to witness China’s films making great achievements. Zhang Hua felt that the more good films she watched, the faster she watched movies in the second half of her life might not catch up with the development of China’s films. But anyway, "I love movies, and I won’t change in my life …"

　　Have all the friends received the goods that they ordered at the "6.18" shopping festival? In the face of mountains of packages, do you have mixed feelings? I was super happy when I placed an order quickly, but look at last year’s double eleven masks. Some clothes and shoes have not even been worn since I bought them, and skin care products and make-up are all over the dressing table … … Originally, it was cheap to spend money carefully, but what I bought was useless, which took up space and wasted money, which made me feel a little depressed.

　　Don’t worry, after reading the following article, you will understand the "emotional value" behind "buy buy Buy" and what "opportunity cost" is, and you will gradually return to rational consumption.

　　Studies have proved that

　　Shopping is happy and stressful.

　　"When I place an order, I think of the scene where I use it. Who will buy useless things? But often most things are useless, and some couriers have been put aside without even being opened. " Xiao a said.

　　Little b: "shopping can make me happy, it doesn’t matter whether it is useful or not!" "

　　Xiao B’s statement reflects the shopping mentality of many young people. If shopping is not to buy "useful" things, then there must be some other motives behind it. As Xiao B said, shopping also carries a lot of "emotional value" for people.

　　Imagine, we came home after a hard day’s work, lying in bed and browsing shopping software at will, and suddenly brushed an inexpensive but useless object that we had long admired. I haven’t placed an order before because "you can buy this thing or not, or don’t buy it", but today is different. I want to buy this thing to comfort myself. "It’s worth spending a little money to make myself happy!"

　　There is a scientific basis that shopping can regulate emotions. Shopping can promote the brain to secrete happiness hormones — — Dopamine starts the reward circuit inside the brain, so we can naturally feel happy when shopping.

　　On the other hand, shopping will make people feel in control, which can release pressure. Scott Rick, an assistant professor of marketing at the University of Michigan in the United States, found that retail therapy is real. Although it is not a psychotherapy method in the strict sense, when making the choice of "buy or not buy", sad people can release their emotions and restore some sense of control over their lives, thus feeling happy.

　　Over 30% of shopping addicts

　　Have a tendency to depression

　　Even if shopping makes people happy, but "indulging in shopping" will bring a lot of people pain. Modern living habits can be said to extend a sinful hand to us and chase and block our little Qian Qian.

　　There is a saying that in the era when mobile payment is not popular, people hold wallets and watch them shrink little by little, and the money in their hands decreases little by little. The insular part of the brain that deals with pain will send out pain signals, which is the so-called "spending money hurts". However, when mobile payment makes us lose our perception of money, people who are not sensitive to digital changes will find that the loss of money will not immediately make waves in their hearts. It was not until the end of the last year that I remembered that this year was "empty to come and empty to go" and I would regret it later.

　　In recent years, many people have also suffered from a new type of disease, compulsive shopping, "pickpocket addiction, not buying." The reason why people are concerned as a disease is that, like drugs, people who are addicted are out of control, and feel remorse afterwards, and in severe cases, they will be depressed.

　　A study by behaviorists found that 31.9% people who are addicted to shopping are prone to depression. The study concludes that guilt after spending money is the chief culprit, which will bring many negative emotions such as low self-esteem, embarrassment and anxiety, and the economic burden brought by excessive spending will also bring people continuous pressure and further aggravate their psychological problems.

　　Not just spending money.

　　It also consumes the "opportunity cost"

　　So, how to control your out-of-control material desires? There are naturally many methods, whether it is bookkeeping or "letting stand" the items added to the shopping cart for a few days. If you want to change, you can naturally find many suggestions. However, the premise of control is to know that one’s behavior is "out of control", and middle-aged and elderly people face a higher cost of living, so most of them will spend cautiously, and it is the young people born after 1990s and 00s who need to pay attention to the impact of excessive shopping on their lives.

　　Take the post-90s generation as an example. An e-commerce platform once published a report on the consumption and life of young people, which showed that among the nearly 170 million post-90s generation in China, the number of people who opened consumer credit services exceeded 45 million, which means that one in every four post-90s generation has the demand of "spending money tomorrow".

　　Few young people around me are misers. More people love money but spend more. They know that they are beyond their ability, but they still can’t help but "chop their hands". They arrange several entertainment bureaus every once in a while, and a year’s savings give them a trip that they just leave. Some young friends once said categorically that if they can’t spend the money they want, how can they appreciate the unrestrained life?

　　Indeed, shopping itself is not useless, and it can also bring us happiness. Many people have not reached the level of shopping addiction, self-loathing and economic collapse. But for young people, the price worthy of vigilance is that the money spent is also the "opportunity cost" that we can’t spend money on other things. No one likes to make a living, but if we have a dream to realize and want to spend money to buy knowledge and ability for ourselves, we have to start by saving a cup of milk tea every day, going to bars less and exercising restraint every time we make impulse shopping.

　　Shopping is pleasant, but it is only a kind of pleasure. Every money spent is a choice. I hope we can all make better choices.

　　In June, many print shops in universities began to get busy. Papers are printed and bound from here, and the eyes of college students around the machine are full of expectation, comfort and a little relief. Those who can walk into the print shop are the "winners in life" in this graduation thesis season, because they have finally reached the final step of graduation thesis completion.

　　In the dormitory next to the printing shop and in the library not far away, many students are still revising their papers over and over again. The hot topic "How strict is the duplicate checking of papers" in Weibo, which has a reading volume of 150 million, is all their voices. Last year, after the university entered the "strict era", the auditing standards for graduation thesis in colleges and universities have improved a lot. Therefore, this essay season is much more difficult for many college students than in previous years.

　　Strict word is the first word, and the paper "paddling" has become a past tense.

　　"Are you sleeping? But I can’t sleep while I’m writing a paper. " Many students sigh in the circle of friends late at night.

　　Qu Weiwei, a master graduate from a university in Hunan Province, found that this year’s graduation season was more difficult than last year.

　　"The school obviously has much higher requirements for graduate students than last year. Our paper duplicate checking standard is 20%. Even if the paper didn’t meet the duplicate checking standard before, it can be changed to more than 30% ‘ Paddle ’ Passed, but now it is stuck 20%. " Qu Weiwei said.

　　As early as last September, the Ministry of Education issued the Notice on Paying Close Attention to the Implementation of the Spirit of the National Conference on Undergraduate Education in Colleges and Universities in the New Era, emphasizing that colleges and universities should comprehensively sort out the teaching contents of various courses, eliminate "water courses", create "gold courses", strictly control the exit of graduation, and resolutely cancel the "clear examination" system.

　　In October of the same year, the Opinions on Speeding up the Construction of High-level Undergraduate Education and Comprehensively Improving Talents Training Ability (hereinafter referred to as "40 Articles on Higher Education in the New Era") issued by the Ministry of Education clearly stated that the whole process management of graduation design (thesis) topics selection, topic opening and defense should be strengthened, and the form, content and difficulty should be strictly monitored to improve the quality of graduation design (thesis). Strengthening the management of undergraduate graduation project (thesis) is a measure to pay close attention to undergraduate education and teaching.

　　This year’s graduation season, many colleges and universities have strengthened their management on "strict out". In April, Tsinghua University released the latest revised "Detailed Rules for the Implementation of the Administrative Provisions on Disciplinary Actions of Students in Tsinghua University", in which the remarkable change is that the punishment for academic misconduct has been increased, and the plagiarism of dissertations can be expelled from school. The original punishment was to give "the above punishment."

　　On May 6th, the Academic Affairs Office of Emei Campus of Southwest Jiaotong University issued the Notice on Doing a Good Job in Checking the Duplicate of Graduation Design (Thesis) in 2019, which shows that the duplicate checking of graduation design (Thesis) will increase the comparison database of college students’ theses (including this one). If students from the same department and school are found to plagiarize from each other, the Academic Affairs Office will start the investigation procedure, and the situation will be dealt with strictly.

　　In addition, the school also requires teachers and students to sign a "commitment letter", promising that they have studied the Measures for Dealing with False Dissertations by the Ministry of Education, the Notice of the General Office of the Ministry of Education on Strictly Investigating the Sale and Writing of Dissertations in Colleges and Universities, etc., and strictly implement the requirements of the Ministry of Education and the school on the management of graduates’ student status, curriculum assessment and graduation design (thesis) documents.

　　"In the past, because of the wide policy, we can use Taobao, which is not accurate but affordable, to check the weight, but now it is required to be based on HowNet, and each check needs more than 200 yuan." Qu Weiwei said.

　　Behind the word "Yan", the pain in the essay season is usually "lack of cultivation"

　　For many college students, the "difficulty" of the thesis season is the whole process, from the topic selection to the thesis defense.

　　In the view of Wang Xudong, a senior student in the School of Computer Science, Huazhong University of Science and Technology, writing the paper itself is not the most difficult, but the experimental part in the paper. He said that at the beginning of his graduation project, the topic selection and opening defense were relatively simple, but he was still secretly "glad" when he encountered a series of troubles.

　　"Because of a small formula error, hundreds of calculation results were all invalid, and a week’s efforts fell short. Every time I finally made new progress, I took it to discuss with my teachers and seniors, and then I found myself making many low-level mistakes, so I had no choice but to start all over again. In addition, because my graduation project is a theoretical research, I can’t prove the theoretical results through rigorous experiments with my current ability. This is also a problem I have encountered, that is, there is no strong practice to support the theoretical conclusions. "

　　Yu Zhenyuan, a senior graduate of Xi ‘an Jiaotong University, said that the graduation process was "extremely difficult". "I need to use a more complicated test-bed for my graduation experiment, but any link of this test-bed will go wrong. We have to fix it from beginning to end. In the experiment, what I don’t know accounts for the majority, and what I can really understand accounts for the minority. My data are very strange. "

　　In addition to the hardware itself, accurate chemical experiments also have high requirements for personal operation. On the morning of the interview with China Youth Daily and Zhongqing Online reporter, Yu Zhenyuan broke the instrument due to operational errors, which made him very upset.

　　Regarding the "pain" of college students in the graduation thesis season, Xu Fei, president of Southwest Jiaotong University, said in an exclusive interview with China Youth Daily and Zhongqing Online reporter that "students have problems in knowledge, ability and expression, and graduation thesis writing makes these problems gather together, which leads to the misery of students."

　　Xu Fei believes that the quality of college students’ graduation thesis is not high at this stage, which is mainly reflected in the lack of solid knowledge, the lack of depth and comprehensive ability of students to master theory, and the poor ability of independent thinking, investigation and research, problem solving and analysis, which leads to the lack of novelty, depth and innovation in the research topic of graduation thesis.

　　"If a student usually does well, he should not feel very painful when writing a paper. Instead, the paper should be a stage for him to show himself." Xu Fei said.

　　What abilities can solve the problem of "paper difficulty"

　　In recent years, many experts and college teachers have said that the poor quality of college students’ graduation thesis is mainly due to their lack of study and training in scientific writing, which leads them to write their graduation thesis for the first time in their lives. Students don’t know where to start, instructors are miserable, and the quality of papers is often not high.

　　In this regard, Xu Fei believes that it is necessary to improve students’ scientific writing level, and senior undergraduate students should set up relevant elective courses to teach students how to conduct scientific research and academic writing, or give guidance to students on how to write graduation thesis through academic lectures.

　　Last year, Qiu Yong, president of Tsinghua University, announced the opening of "Writing and Communication" course for freshmen in 2018, which is expected to cover all undergraduates by 2020, and strive to provide courses and guidance for graduate students. This has aroused widespread concern in society. At the end of May, Tsinghua University Writing and Communication Teaching Center issued a notice for recruiting teachers, and recruited 10 more teachers for outstanding scholars, postdoctoral students and fresh doctoral students at home and abroad.

　　It is reported that the course adopts two parallel modes: one credit and two credits. What each class teaches together is mainly the paradigm of reasoning writing and how to modify and perfect an article. More specifically, it mainly includes choosing the topic, sorting out the ideas of the article, establishing the logical structure, checking and modifying the grammatical errors, elegant expression, etc., but the topic is chosen by the students themselves. It is not mandatory to use uniform teaching materials in the course, but the consistency of training requirements in the whole process is important.

　　Peng Gang, a professor in the history department of Tsinghua University and director of the Academic Affairs Office, once said that writing training should first be thinking training. "It is very important for students to find a problem and think from different angles. If you want to write, you must first learn to think, and learn to think methodically and hierarchically. This is also the highest standard I expect: the writing course not only exercises students’ writing ability, but also enables students to ‘ Open your eyes ’ General course ".

　　As for the students’ "miserable" in the graduation thesis season, Xu Fei thinks that there are several reasons besides the lack of writing ability.

　　From the students’ point of view, they usually have a lot of knowledge, but they are not solid enough to learn, and there is a phenomenon of superficial and superficial. Students rely too much on search engines in their daily study, and there are deficiencies in memory and independent thinking. "Everything is at your fingertips, and everything has an answer. Students will feel ‘ Why am I still studying ’ This is a big misunderstanding. "

　　On the other hand, students’ knowledge is fragmented, not structured, organized and systematic, and they have not incorporated other people’s knowledge into their own knowledge system. This leads to students being "dumbfounded" when they finally need organized text presentation.

　　Moreover, "many schools are short of teachers, and teachers put more energy into scientific research. In terms of teaching, the energy put on undergraduates is different from that put on master students and doctoral students. Undergraduates are the group with the least energy input from teachers, which is also an important reason for the difficulty in writing students’ papers. "

　　Xu Fei believes that although from the perspective of academic degree regulations, undergraduates are not like master students and doctoral students, they have to submit papers to obtain their degrees, but it is necessary to adhere to the practice of requiring undergraduates to submit graduation papers. "Graduation thesis can comprehensively show and test students’ mastery of what they have learned and their ability to solve practical problems by using what they have learned. It is more important for undergraduates to write graduation thesis, from topic selection to data collection, to paper organization, writing, revision and final drafting, which is the most basic process of academic research and academic training".

　　"Graduation thesis is the last big homework for students." Xu Fei said.

　　Xinhua News Agency, China Photo Agency and Nut Projection Light up the Star Map of China.

　　On this year’s Qixi Festival (August 4th), China Photo Agency jointly organized a special activity of "Lighting up the Star Map of China-Lighting up Greater Bay Area" with JMGO Nut Projection. The theme of the activity is "romantic starry sky companionship", which aims to advocate people to spend more time with their families, relatives and friends in modern life, return to nature and embrace nature.

　　At the event site, nut projection CPO Wang Xiaoyi Will not only shared the possibility that electronic products can provide people with wisdom and warm companionship, but also brought a special projection product: nut ultra-short focal O1S.

　　Different from the household projection we have seen before, the nut O1S can be cast on the wall, ignoring the space requirements, which means that for small-sized consumers and renters, you can also enjoy the big-screen viewing experience in the bedroom. On the system level, Nut O1S has added a companion mode to the original viewing mode. The rhythm of light and shadow creates an immersive scene experience, and the personalized wall is different. Musical rhythm adds more atmosphere. The new projection gameplay makes Nut O1S an ultra-short focus projector not only a projector, but also a "companion".

　　Leading the nut projection in science and technology industry for continuous innovation

　　Looking back, the development of nut projection is a history of projection innovation. Since the first product equipped with intelligent system (nut A1) was founded and released in 2011, nut projection has been the leading position of projection technology for eleven years. For example, in 2014, the first Nut G1, which integrates Bluetooth speaker, intelligent system and electric focusing, allowed more families to incorporate projection into required appliances; In 2018, Nut X3 and Nut U1 were released, opening a new era of 4K; In 2020, from the nut G9 with non-inductive autofocus to the nut J10 with automatic obstacle avoidance and automatic screen alignment, the intelligence will enter the public’s field of vision adaptively. In 2021, Nut created a brand-new ultra-short focus category. As the first ultra-short focus projection equipped with dual-mode system, Nut O1 can enjoy a big-screen life in a small space.

　　In the face of numerous industry innovations and initial launches, nut O1S is just a "insignificant" link in the whole innovation history of nut projection.

　　The New Revolution of Nut’s New N1 Series Projection Experience

　　Despite the fruitful innovation, nuts have never stopped on the road of innovation. This time, nuts have set their sights on the "telephoto projection" category. Different from the previous stereotype that telephoto projection can’t catch up with TV and the use conditions are harsh, the Nut Projection N1 series brings a brand-new projection experience. Through the core self-developed MALC? Three-color laser optical machine combined with Leica for color adjustment and integrated pan-tilt projection technology have solved two major pain points that have long plagued projection consumers-poor image quality and poor convenience.

　　Master the core technology by self-research, and let household projection enter the era of tricolor laser.

　　From being monopolized by overseas brands to being captured by domestic brands in the opposite direction, the competition in the home projection market has already become fierce, and the dispute over homogenization parameters has become a thing of the past, and domestic manufacturers have entered the stage of fighting for technology and products. In this context, nuts focus on technology research and development. After two years of spending tens of millions, nuts have successfully developed their own "MALC mesh krypton?" Tri-color laser optical machine has successfully solved the three big problems: cost, volume and speckle, which block the application of tri-color laser in the field of home projection, and brought about a revolution in image quality for home projection.

　　Objective Krypton optical machine has three core technologies: modular laser stacking technology, the first patented LSR dynamic speckle dissipation technology, and a 400-zone four-layer compound eye homogenizing system.

　　Modular laser stacking technology solves the problem of high cost and large volume of three-color laser. Each projection of Nut Projection N1 series is equipped with three leading 9-chip (4R3G2B) lasers (laser model is NUMB12T), which improves the optical efficiency by 10%, reduces the volume by 40%, improves the heat dissipation performance by 10%, and brings 110% BT.2020 color gamut performance.

　　The first patented LSR dynamic speckle elimination technology can eliminate the speckle problem caused by tricolor laser in a targeted way, and surpass the mainstream level of the industry to achieve more than 95% speckle elimination.

　　The 400-zone four-layer compound eye light homogenizing system can realize two-stage area light splitting, and through the two-stage homogenization of angle and plane, it can realize the fine light homogenizing of about 45,000 tiny areas, and the uniformity can exceed 95%, and at the same time, it can improve the uniformity of brightness and color remarkably.

　　Thanks to the krypton optical machine, Nut N1 has made a new breakthrough in image quality. The brightness of 4000ANSI lumens makes household projection fearless in the daytime. The color gamut coverage of 110%BT.2020 is more than that of 10,000 yuan TV, and the contrast ratio of 1600: 1 is three times that of LED projection. The parameters alone have surpassed all household display devices in the market.

　　Integrated pan/tilt, home projection ushered in the first complete form

　　If we say that solving the problem of "poor image quality" makes telephoto projection "look cool", then we must solve the problem of "poor convenience" of telephoto projection and let users "use it cool". Nut Projection N1 series is an original PTZ projection, which integrates the PTZ design used only for drones and mobile phones into the projection equipment, making the triviality a thing of the past and jointly creating a pluralistic and free lifestyle.

　　Nut projection can be controlled by one hand through the self-developed ultra-thin two-axis pan-tilt structure, and it can easily rotate and hover freely, covering all use scenes from the corner to the ceiling, whether sitting or lying down, and realizing free viewing at will.

　　The morphological words of Nut N1 series not only stay in the physical structure, but also deeply combine the gradient correction and focusing algorithm in the projection, which brings a brand-new cloud desktop picture correction. When the projection is rotated, the correction algorithm has already acted, and the picture at any angle can be clear at all times. Different from other projections, which start to correct the picture after the movement, Nut N1 series really achieves the real-time picture calibration and experiences the unburdened projection life. According to Nut, the ultimate mission of picture calibration of PTZ projection is to make consumers forget the concepts of keystone correction and focusing in the projector, just as watching TV never needs these picture calibration operations.

　　With the nut self-developed ultra-thin two-axis pan-tilt structure and pan-tilt picture calibration algorithm, the nut projection N1 series will be the first equipment with complete projection form.

　　It can be seen that the N1 series of Nut Projection will continue its leading position in projection technology for eleven years. As pioneers rather than followers of the industry, we have reason to believe that Nut Projection will continue to pursue breakthroughs and be brave in innovation in the field of science and technology, and will lead China science and technology enterprises to a broader stage in the near future.

　　According to the website of Manzhouli Municipal Government, the COVID-19 Epidemic Prevention and Control Command of Manzhouli City issued a notice saying that on February 15th, 2022, five cases of COVID-19 nucleic acid positive people were found in Manzhouli City.

　　The follow-up situation will be announced to the general public in a timely manner.

　　In order to promote young scientific and technological workers and inspire new academic ideas, the 2019 annual meeting of science and technology of the Chinese Academy of Environmental Sciences held in Xi ‘an, the ancient capital, opened up a "Young Scientists’ Special Session", which provided a stage for exchanges and discussions for young scholars and technical talents who have emerged in recent years around the theme of "environmental science and technology innovation helps fight against pollution". Previously, the Chinese Society of Environmental Sciences just announced on its website 30 candidates who were awarded the "Young Scientists Award of the Second Chinese Society of Environmental Sciences", including 10 gold medals and 20 excellent prizes.

　　On the afternoon of August 23rd, the "Special Session for Young Scientists" was co-chaired by Lu Xi, Secretary General of the Young Scientists Branch of the Chinese Society of Environmental Sciences, and Professor Chen Rong from the School of Environment and Municipal Engineering of Xi ‘an University of Architecture and Technology. A total of eight representatives of young scientists gave speeches at the scene, and each of them contributed forward-looking content during the 30-minute on-site report time, which greatly expanded the participants’ cognitive and knowledge horizons. Let’s take a look at the contents of their report.

　　Magnetic nano-materials have great potential for environmental applications.

　　The first person to take the podium was Zhao Xiaoli, a researcher from china environmental science Research Institute. The topic of her report was "Application Research of Magnetic Nanomaterials in Analysis and Degradation of Pollutants". She starts with what we usually hear about nano-materials, which are artificially synthesized by people to meet the purpose of use, and are also research hotspots in recent years. In addition, there are some man-made nano-pollutants, such as nano-pollutants released into the atmosphere and water bodies by garbage incineration and industrial production.

　　In the field of international nanotechnology, researchers’ understanding of nanomaterials has experienced a development process from new products to new pollutants to nano-safety. With the increasing application of nano-materials, its biological toxicity has attracted people’s attention. How to promote the healthy development of the industry and produce engineering nanomaterials that can meet the application needs and are environmentally friendly? Zhao Xiaoli’s team focused on the application of nanomaterials in the analysis, adsorption and degradation of pollutants in the water environment. Because nanomaterials are easy to block and difficult to separate, her team combined magnetic materials with nanomaterials to get magnetic nanomaterials. Magnetic nano-materials combine the advantages of small particle size, short diffusion path and fast extraction speed.

　　Next, she and her team worked hard to solve two key problems. One is that magnetic nanomaterials should be synthesized in a controlled and stable way, and the other is the adsorption capacity of magnetic nanomaterials to organic pollutants. For this reason, they independently prepared more than 10 kinds of nano-Fe3O4 composites with uniform particle size and controllable surface structure, which can be used for comparative research, and developed a new method for rapid analysis of trace pollutants in environmental water based on magnetic separation. Experiments show that the magnetic nano-materials developed by them have great potential for environmental application in pollutant analysis, adsorption removal and catalytic degradation, and solve the key problem of solid-liquid separation of nano-materials in solid-phase extraction application.

　　Environmental DNA is a powerful tool to detect and quantify biodiversity.

　　The topic of Professor Zhang Xiaowei’s report from School of Environment of Nanjing University is "eDNA Shaping a New Era of Eco-toxicology Research". Starting with a picture overlooking the bright lights in Asia at night from a satellite, he introduced the great changes brought by economic development to the natural ecological environment and landforms. Due to industrialization and urbanization, various environmental stress factors have entered the eco-environmental system, and many toxic substances have led to the decline of a large number of species through various mechanisms. In order to evaluate the chemical toxicity of species, countries have formed a set of simple strategies to evaluate the environmental quality of ecological risks in the past 50 years, which mainly include two methods: one is instrumental analysis, and the other is laboratory toxicity test. These methods are time-consuming and laborious, so the monitoring of wild native biota is considered as the key weakness of current ecotoxicology research.

　　In order to overcome the above weaknesses, Zhang Xiaowei and his team began to use eDNA method to apply and popularize biodiversity monitoring technology in 2016. The so-called eDNA is the DNA in environmental samples, one is the DNA of biological individuals, and the other is the free fragments of large animals. EDNA’s sedimentation, degradation and final diffusion can be simulated by one-dimensional equation, which can predict the degradation and migration of eDNA in the process. Compared with the traditional morphological verification method, it provides a monitoring technology with higher repeatability and resolution.

　　The magic of eDNA technology is that by analyzing the substances in a glass of water, we can know what zooplankton and fish are in the ecological environment at that time. Zhang Xiaowei shows through several cases that eDNA can be used to monitor the swimming track of Yangtze finless porpoise population, and display the distribution and biodiversity of fish and plankton, which is undoubtedly very beneficial for comprehensively evaluating the long-term effects of environmental stress factors on regional ecosystem and its mechanism.

　　New technology makes offshore oil and gas exploitation cleaner.

　　Professor Yang Qiang from School of Mechanical and Power Engineering, East China University of Science and Technology gave a report entitled "Complete Technology and Equipment for Efficient CFC Treatment of Offshore Platform Production Wastewater". Yang Qiangxian introduced the research background of the project. At present, the process of oil and gas resources exploitation in China is simply to treat the oil-gas-water mixture on the platform after drilling, purify the water and transport the oil and gas to the shore for utilization. In this process, every ton of oil produced is accompanied by 3 tons of water brought to the ground, which is partly reinjected into the underground and partly discharged into the sea. It is a key problem for the production of offshore oil platforms in the world to control and treat the discharge of these wastewater.

　　The existing offshore platforms in China are basically physical methods and a small amount of chemical methods. Yang Qiang’s team built a droplet control system to solve the problem of how to separate oil in water efficiently, and studied the process from the adhesion of oil droplets on the whole fiber level to the collision, separation and collision fusion of oil droplets. Then, based on the mechanism of fiber-induced agglomeration, the team proposed to use lipophilic fibers to quickly capture high-viscosity heavy oil droplets during the flow process. Aiming at the problem of gas in oil and oil in water, the research team constructed a combination of oleophilic fiber and oleophobic fiber to realize the physical separation process. On this basis, they developed hydrophilic/lipophilic combined fiber coalescence oil removal technology and equipment, and constructed a complete set of production wastewater treatment process with this technology and equipment as the core. Finally, Yang Qiang introduced the application of their technical equipment in Yacheng 13-1 gas field in the South China Sea and Caofeidian oil and gas field in the Bohai Sea. Practice has proved that good treatment results have been achieved in the source control of marine pollutants.

　　Satellite remote sensing implements the supervision of nature reserves.

　　Hou Peng, a senior engineer of the Satellite Environment Application Center of the Ministry of Ecology and Environment, gave a report entitled "Study on the Technical System and Operational Mechanism of National Ecological Supervision in Nature Reserves". Hou Peng first introduced the current situation and main control requirements of nature reserves in China. Nature reserves are natural treasures, but as of 2018, the proportion of protected land to land and sea in China is still far from the goal of 2020 proposed by the Convention on Biological Diversity. How to realize the operational operation of ecological supervision in nature reserves and ensure the bottom line of national ecological security is an important proposition of social sustainable development.

　　Next, Hou Peng explained the operational technical system and operational mechanism of monitoring and evaluating the effectiveness of human activities and ecological protection in nature reserves from the two major needs of supervision and law enforcement and comprehensive decision-making, mainly driven by satellite remote sensing technology. For the supervision of human activities, he focused on the working mechanism of satellite remote sensing monitoring discovery and national and local coordinated operation; Regarding the effectiveness of ecological protection, he took the composition of ecosystem types and the service function of ecosystem as the main line, put forward the framework and index method of effectiveness evaluation of nature reserves, and constructed the evaluation model of ecological security contribution. Their research results have achieved remarkable results in the monitoring and management of the northern foot of Qinling Mountains, and have well implemented the requirements of the central authorities on strengthening ecological protection.

　　Pyrolysis gasification technology makes garbage disposal in small cities and rural areas more economical and environmentally friendly.

　　Zhao Ming, a special researcher of Tsinghua University Institute of Environment, gave a report entitled "Clean Gasification Technology of Organic Solid Waste with High Heat Value". He believes that the pilot project of "waste-free city" is actively carried out in the country, which embodies the new concept of solid waste pollution control in the new period-full source reduction and "zero landfill" terminal disposal technology, which is also in line with the requirements of the 19th National Congress report and some recent policies on garbage disposal. According to Zhao Ming’s observation, the pattern of "large-scale incineration" (the daily treatment scale is more than 600 tons) in big cities with high population concentration seems unshakable at present, but for the domestic garbage in the vast counties, as well as the obvious industrial organic solid waste and organic hazardous waste in the region, the demand for miniaturization treatment (200 tons/day or less) makes pyrolysis gasification an alternative route for incineration.

　　Through calculation, Zhao Ming thinks that the current hazardous waste incineration produces a large amount of residue per ton, which will be greatly reduced if melting technology is adopted, and the power consumption of the whole process is much lower than that of the safe landfill plant, so gasification pyrolysis is a more economical way. More can be done for solid waste energy with high calorific value, for example, it can be turned into clean gas. In his view, the upstream of pyrolysis and gasification is connected with garbage classification to ensure the homogeneity and high calorific value of materials, and the downstream is connected with distributed production capacity to realize the multi-use of heat, electricity and chemistry, so it is expected to become a miniaturized mainstream technology with less land occupation, less investment, easy control of secondary pollution and high energy conversion efficiency. At present, Zhao Ming and his team have done some industrialization exploration besides technology, which is expected to be realized in two to three years.

　　Beijing-Tianjin-Hebei bid farewell to smog.

　　Lei Yu, a researcher at the Institute of Environmental Planning of the Ministry of Ecology and Environment, gave a report entitled "Study on Atmospheric Environmental Capacity and Air Quality Improvement Path in Beijing, Tianjin and Hebei and Surrounding Areas". When expounding the research background of his report, he introduced that intensive social and economic activities and large industrial emissions in Beijing-Tianjin-Hebei region are the main causes of pollution in this region, while local topography and winter meteorological conditions aggravate the degree of pollution. According to his research, after analyzing and summarizing the simulation results of air quality model under meteorological conditions year by year since 2000, it can be found that the influence of meteorological conditions on the annual average concentration of PM2.5 in the region can reach up to plus or minus 10%. Through the analysis of the model iterative algorithm developed based on WRF-CMAQ, it is found that the emission of major air pollutants in the region needs to be reduced by more than 50% on the basis of 2016, subject to the annual average concentration of PM2.5 reaching the standard.

　　In his research, Lei Yu analyzed the characteristics of PM2.5 concentration in Beijing, Tianjin and Hebei, and gave three scenarios: the first scenario is required by the "Thirteenth Five-Year Plan" goal; The second is the scenario of classification improvement-he thinks that the rate of decline in cities with relatively high concentrations should be faster; The third scenario is given a relatively more radical requirement, and the third scenario is in line with the current "beautiful China" construction and the target requirements put forward by the 19th National Congress. Finally, he introduced what measures can make the whole region reach the above expectations. For this reason, the research team spliced several models and put forward the technical path and phased goal of improving regional air quality. Finally, he pointed out that although the ozone concentration is increasing in recent years, the concentrations of sulfur dioxide and nitrogen oxides are decreasing, so he believes that the ozone concentration will gradually decrease, which will also strengthen the confidence of policy makers.

　　Remote Sensing Monitoring Helps Pollutant Transmission Control

　　Liu Cheng, a professor at the School of Earth and Space Sciences, University of Science and Technology of China, reported on the topic of Stereo Remote Sensing Monitoring of Air Pollution. With the implementation of "Ten Articles on Atmospheric Countries", although China has set quantifiable targets for Beijing-Tianjin-Hebei and Yangtze River Delta, the air pollution in a place is affected not only by local emissions and secondary generation, but also by regional transmission. To carry out the main responsibility of pollution control, it is necessary to clarify the relative contributions of local emissions and foreign transportation, which provides a place for remote sensing technology. It is from this that Liu Cheng’s research starts to achieve the goal of control and governance of pollutant transmission.

　　Stereo remote sensing monitoring is an important field of atmospheric environment research. With the progress of scientific hardware, the high resolution of satellite remote sensing can accurately capture the source of factory emissions, including sulfur dioxide, formaldehyde and ozone. In the research, Liu Cheng and his team carried out research on the spatial and temporal distribution, sources and mechanism of atmospheric pollutants based on ground-based, ship-based, airborne and satellite-borne three-dimensional remote sensing monitoring platforms. Through calculation, researchers found that the accuracy of satellite remote sensing monitoring is very high, and related research results and models have also been accepted by top international journals. In addition, the ship-borne remote sensing aerial survey of the Yangtze River found that the pollutants in economically developed provinces mainly came from factories, while those in agricultural provinces mainly came from automobile exhaust. The researchers also participated in the research on the cross-border transport of pollutants among China, Japan and South Korea. They drove from Dalian to South Korea with instruments carried by ships to observe how many pollutants were transmitted from China to South Korea and how many pollutants were introduced from South Korea to China.

　　New catalysts make typical environmental pollutants have nowhere to hide.

　　Professor Zhan Sihui from the School of Environmental Science and Engineering of Nankai University gave a report entitled "Study on Pollution Control Mechanism of Typical Environmental Pollutants". At present, the removal of environmental pollutants often relies on environmental catalysis and has achieved good results. However, the commonly used catalysts are actually prone to poisoning and fire, and how to further improve their effects in practice needs to explore their microscopic mechanisms. In order to efficiently remove pollutants in a complex environmental system and maintain the stability of the catalyst, Zhan Sihui and his team envisaged the process of catalytic oxidation integration through surface modification and regulation of materials.

　　The researchers first designed a new type of catalyst through surface acidity regulation and surface redox regulation, revealing the mechanism of solid-gas interface regulation and adsorption-activation-purification of pollutants. After that, they constructed a chemical targeted purification system of pathogenic microorganisms at the solid-liquid interface, which solved many kinetic problems and non-targeted purification problems existing in the original disinfection process. Finally, through the adjustment and modification of the interface, the research team can produce more activity and improve the efficiency of adsorption, oxidation and catalysis of typical environmental pollutants. Zhan Sihui said that their research results have been transformed after cooperation with the military, and the designed operation process of quickly removing typical pollutants under photosynthesis can be used to ensure the safety of drinking water in the wild, which also makes great contributions to the microbial detection of water quality.

　　At the moment when the construction of ecological civilization has become a national strategy, the demand in the field of environmental protection scientific research has pointed out the direction for scientific research and provided a rare opportunity for the growth of young scientists. When reporting the research results, the young scholars who gave reports on the spot said that they were excited to get such an opportunity to show their achievements at the national level, which showed that the Chinese Society of Environmental Sciences attached great importance to the growth and training of young scientists. We expect the vast number of young eco-environmental science and technology workers to show greater innovation and scientific research vitality and realize greater life value on the broad environmental protection stage.

　　It is said that the custom of eating moon cakes in Mid-Autumn Festival can be traced back to the Tang Dynasty. For a long time, moon cakes have been integrated with local food customs, and gradually formed five "schools" of moon cakes: Cantonese, Beijing, Suzhou and Chaozhou. Nowadays, the traditional taste can’t fully meet people’s demand for moon cakes, so all kinds of exotic moon cakes and online celebrity moon cakes have broken into the "rivers and lakes" of moon cakes and become new choices for Mid-Autumn Festival consumption.

　　Cantonese-style moon cakes: Cantonese-style moon cakes are the most popular among the people at present. They originated in Guangdong and its surrounding areas and have been popular all over the country. They are characterized by thin skin and large stuffing, and the oil content of the skin stuffing is higher than that of other genres.

　　Beijing-style moon cakes: Beijing-style moon cakes reuse sesame oil, which reveals a sense of wealth at the foot of the imperial city. Legend has it that there was a serious plague in Beijing in ancient times. In the Guanghan Palace, Fairy Chang ‘e ordered the jade rabbit who pounded the fairy medicine for her to come down to earth to treat the suffering people, that is, the rabbit. Rabbit cured the people of the whole city with red and white medicine and returned to the Moon Palace. These two kinds of medicine evolved into natural white and natural red moon cakes, which are the representatives of Beijing-style moon cakes.

　　Su-style moon cakes: Formerly known as crisp moon cakes, they originated in Shanghai, Jiangsu, Zhejiang and surrounding areas, and were later handed down as Su-style moon cakes. The main feature is that the crust of the cake is loose, and the fillings are five kernels and bean paste, which are sweeter than other kinds of moon cakes. The main products are Su-style moon cakes with fresh meat and Su-style moon cakes with black sesame seeds.

　　Chaozhou moon cake: also known as Chaozhou fork cake, fork word, Chaoshan dialect refers to lard. Chaozhou-style moon cakes have a flat body, a white crust, crispy stuffing and a crisp entrance. The main characteristics are that the crispy skin is thin, the oil is not fat, and the mouth is not greasy. According to the types of stuffing, it can be divided into mung beans, black beans, crystals, purple taro and other types, while the inner core includes egg yolk or seafood.

　　Yunnan-style moon cakes: It is said that the emperor of Nanming small court who retired from Kunming in the late Ming and early Qing dynasties was worried about tea and rice all day long, and a royal chef chose Yunnan ham meat to cut into pieces and mixed it with honey sugar to solve the emperor’s homesickness. Later, this practice spread to the people, and after several improvements, ham moon cakes gradually became a major feature of Yunnan moon cakes.

　　Once, netizens launched a cyber war for the argument of "Let Wuren get out of the mooncake world". Now, more incredible mooncakes are born, and netizens have said that there will be a blood shed in the mooncake world! For example, this "leek egg" moon cake is covered with eggs, which adds up to the flavor of leek eggs!

　　There are also these bullish "super luxury version" moon cakes: bullfrog moon cakes, abalone moon cakes and crayfish moon cakes!

　　In addition to those wonderful mooncakes that are "endless with words", many big brands have cooperated with mooncake manufacturers to launch the creative "online celebrity Mooncakes". For example, this moon cake set with the shape of "Moon Rabbit" and "Xiangyun" launched by the Palace Museum is deeply loved by netizens, and netizens have commented that they are "crying"!
