　　When presiding over the sixth collective study in the Political Bureau of the Communist Party of China (CPC) Central Committee, General Secretary of the Supreme Leader emphasized that "we should pay attention to drawing theoretical innovation wisdom from the creation of the masses". If a society wants to be prosperous and full of vigor and vitality, it must constantly carry out theoretical innovation. People’s nature is the essential attribute of Marxism. The Party’s theory comes from the people, for the people and for the benefit of the people. The people’s creative practice is an inexhaustible source of theoretical innovation. The important exposition of the Supreme Leader General Secretary adheres to the Marxist historical materialism and the standpoint of people first, which clarifies the source of the party’s theoretical innovation and provides a fundamental follow-up for constantly writing a new chapter in the modernization of Marxism in China.

　　The people are the creators of history.

　　Marx and Engels systematically thought about the relationship between man and history, holding that the primary premise of human history is "the existence of living individuals", and pointed out that history is the history of living people in material form, not the history of spirit or will. Social existence determines social consciousness and mode of production determines social development, which is the basic viewpoint of Marxist historical materialism. Material production activities are the basic conditions of all history, and all social life is practical in essence. Marx clearly pointed out in the Manuscript of Economics and Philosophy in 1844 that history "is nothing more than a process in which people are born through human labor, and it is a process in which nature generates for people". Man creates history through his own practical activities, and social history is composed of his practical activities, and man is the real subject of social history.

　　The people are the creators of material wealth and spiritual wealth. Marxist historical materialism holds that people’s practical activities not only create an objective material world, but also create a rich spiritual world. The people are the creators of material wealth. Material production is the premise of all history. Without certain material production, there can be no human history. The material materials needed for human survival and development are produced by the broad masses of the people. As the main body of material production activities, the people constantly accumulate production experience in practice, innovate and create production technologies, and promote the development of productive forces and the growth of social material wealth. The people are also creators of spiritual wealth. Social existence determines social consciousness, which is a reflection of social existence. The production practice of the people provides a material basis for the creation of spiritual wealth, and all spiritual wealth is rooted in the practical activities of the people.

　　General Secretary of the Supreme Leader pointed out: "The people are the driving force to create history, and we communist party people should never forget this most basic truth of historical materialism." Productivity is the fundamental driving force for the development of human society. The contradictory movement between productivity and production relations promotes the continuous development of human society, and the people are the most active factors for the transformation of productivity. The people’s subjective practical activities constitute the foundation of social life, and all social changes are based on this foundation. While creating material wealth and spiritual wealth, the people also create and transform social relations of production. Any social change cannot be separated from the people’s active participation and the people’s enthusiasm and initiative. Marx and Engels pointed out that "historical activities are the activities of the masses, and with the deepening of historical activities, it will certainly expand the ranks of the masses." Although heroes also play an important role in historical development and change, social change ultimately depends on the will, wishes and interests of the broad masses of the people. From the perspective of historical materialism, only the people are the real creators of history and the fundamental driving force for social change and social reform and development.

　　2. People’s creative practice is an inexhaustible source of theoretical innovation.

　　Great times need great theories. The Central Committee of the Communist Party of China’s Resolution on the Great Achievements and Historical Experience of the Party’s Centennial Struggle takes "persisting in theoretical innovation" as one of the historical experiences of the Communist Party of China (CPC)’s Centennial Struggle, and points out: "As long as we are brave enough to combine new practices and constantly promote theoretical innovation and be good at guiding new practices with new theories, we will certainly be able to show Marxism a stronger and more convincing truth force on the land of China." The reason why our party can make great achievements in various historical periods lies in mastering Marxist scientific theory and constantly promoting theoretical innovation in combination with new realities. We should constantly deepen our understanding of the regularity of the party’s theoretical innovation and achieve more fruitful theoretical innovation results in the new era and new journey.

　　Marxist historical materialism points out that theory is a rational social consciousness, and theoretical innovation is the need of the unity of social existence and social consciousness, which cannot be divorced from the objective law that social existence determines social consciousness and social consciousness reacts on social existence. On the basis of material production and spiritual production, people’s understanding of truth is refined and summed up in the cycle from sensibility to rationality to practice. Theoretical innovation must be based on social practice, and the main body of practice is the people. Marxism defines the people’s dominant position in social production practice and points out the "creative" nature of the people in the process of complex social practice. Marxism is a theory that stands for the people and speaks for them. It was founded to change people’s destiny and enriched and developed in people’s practice of seeking liberation. the Communist Party of China (CPC) is a political party guided by Marxism. To promote the party’s theoretical innovation, it must be closely combined with people’s creative practice, which is an inexhaustible source of Marxist theoretical innovation.

　　Looking back on the history of the Party’s struggle for a hundred years, we can see that the reason why our Party has made great achievements in various historical periods of revolution, construction and reform, and has been able to lead the people to accomplish arduous tasks that other political forces in China can’t, lies in mastering Marxist scientific theory and constantly promoting theoretical innovation in light of new realities. He has made great theoretical achievements such as Mao Zedong Thought, Deng Xiaoping Theory, Theory of Three Represents, Scientific Outlook on Development and Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, and has always adhered to emancipating the mind, seeking truth from facts, advancing with the times, seeking truth and being pragmatic, which has made Marxism glow with great vitality in China and enabled the Party to master a powerful force of truth. The party’s theoretical innovation results all come from people’s wisdom, people’s exploration and people’s creation. Adhering to the people’s supremacy is a profound summary of the Communist Party of China (CPC)’s valuable experience in the past 100 years and an unswerving pursuit of value, which is an important embodiment of Marxist people’s view. History has created the Communist Party of China (CPC) in the people’s exploration and struggle, and the Communist Party of China (CPC) led the people to create new historical glory. During the period of new-democratic revolution, socialist revolution and construction, the Communist Party of China (CPC) people, with Comrade Mao Zedong as the main representative, combined the basic principles of Marxism with China’s concrete reality, insisted on integrating theory with practice and keeping close contact with the masses, and with the strong support and sincere support of the broad masses of the people, absorbed the wisdom of the masses and relied on the strength of the people, and founded Mao Zedong Thought through hard exploration. Comrade Mao Zedong pointed out, "As long as we rely on the people,Firmly believe that the creativity of the people is endless, so trust the people and become one with them, and then any difficulties can be overcome. " In the new era of reform, opening up and socialist modernization, the Communist Party of China (CPC) people continue to rely on the creative practice of the people and lead the cause development with theoretical innovation. At the end of 1970s, the practice of "all-in-one contract" from Xiaogang Village, Fengyang, Anhui Province directly started the rural reform in China. The party’s major theoretical innovations all come from the people’s creative practice, which shows the people’s creative wisdom. Since the 18th National Congress of the Communist Party of China, the people of the Communist Party of China (CPC), with the Supreme Leader as the main representative, have persisted in combining the basic principles of Marxism with the concrete reality of China and the excellent traditional Chinese culture, scientifically answered the major issues of the times such as what kind of Socialism with Chinese characteristics and how to uphold and develop Socialism with Chinese characteristics in the new era, and created the Socialism with Chinese characteristics Thought of the Supreme Leader in the new era. The Supreme Leader’s Socialism with Chinese characteristics Thought in the New Era is contemporary China Marxism and 21st century Marxism, and it is the essence of Chinese culture and China spirit, which has achieved a new leap in the modernization of Marxism in China.

　　3. To promote the theoretical innovation of the Party, we must follow the mass line.

　　To promote the party’s theoretical innovation, we must go deep into the people and do a good job of investigation and research. The people are the creators of history and the decisive force to promote social development and change. Investigation and research is the heirloom of our party, the foundation of seeking things and the way to achieve things. Investigation is the source of insight. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has attached great importance to investigation and research. The General Secretary of the Supreme Leader took the lead in setting an example and went deep into the people. The footprints of investigation and research spread all over the country, setting a shining example for the whole party to do a good job in investigation and research. Going deep into the people to do a good job in investigation and research is the basis of continuously promoting the theoretical innovation of the Party, and it is also the practical need to keep sober and firm in solving the unique problems of the big party and answer the "six how to always". To promote the party’s theoretical innovation, we must not build a car behind closed doors, sit and talk about the road, and become a pipe dream. The General Secretary of the Supreme Leader stressed, "We should worship the people as teachers, learn from the people, put down our airs, throw ourselves down, be grounded, understand the situation, conduct in-depth investigation and study, dissect sparrows, find typical examples, truly find out the problems faced by the masses, reflect their opinions and sum up the experience created by the masses." The social practice of the masses is not only the object of our investigation and study, but also the inexhaustible source of our correct understanding. The masses not only know the actual situation best, but also contain the wisdom and strength to solve problems. Only by doing a good job of investigation and study can we continuously promote the party’s theoretical innovation.

　　Promoting the Party’s theoretical innovation must respect the people’s initiative. General Secretary of the Supreme Leader emphasized that "we should respect the people’s initiative, pay attention to summing up fresh experiences from the people’s creative practice, upgrade to rational understanding and refine new theoretical achievements". Respecting the people’s initiative is determined by the nature and purpose of our party, which embodies the Marxist historical values. The development of society is always based on giving full play to people’s subjective initiative and respecting people’s initiative. The will, desire, requirement and practice of the people reflect the trend of social development and embody the law of social development. At present, the changes of the world, times and history are unfolding in an unprecedented way. The "two overall situations" are accelerating and interacting deeply. China’s development has entered a period in which strategic opportunities and risk challenges coexist and uncertainties and unpredictable factors increase. It is even more necessary for us to persist in taking the people as the center, respect the people’s initiative, fully stimulate the creative power contained in the people, pay attention to the unity of top-level design and consultation with the people, and constantly gain new understanding from summing up the people’s creative practice.

　　Let the party’s innovative theory penetrate into the hearts of hundreds of millions of people. Report to the 20th CPC National Congress pointed out that it is necessary to "build a socialist ideology with strong cohesion and leading power" and "improve the system of arming the whole party, educating the people and guiding practice with the Party’s innovative theory". If great thoughts want generate’s great strength, they must be transformed into concrete social practice, rely on the people as the main body of social practice, and make the innovation theory consciously recognized and sincerely supported by the people, making it a powerful ideological weapon to guide the people to understand and transform the world. General Secretary of the Supreme Leader stressed, "Insist on inner-party education to guide and drive the learning of the whole society, and let the party’s innovative theory ‘ Fly into the homes of ordinary people ’ " . Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era is contemporary China Marxism and 21st century Marxism, and it is the essence of Chinese culture and China spirit. We should persist in casting our souls with Socialism with Chinese characteristics Thought of the Supreme Leader in the new era, carry out in-depth study, publicity and interpretation in the whole party and society, guide the broad masses of party member, cadres and the masses to deeply understand the decisive significance of the "two establishment", strengthen the "four consciousnesses", strengthen the "four self-confidences" and achieve the "two maintenance".Consciously maintain a high degree of unity with the CPC Central Committee with the Supreme Leader as the core in ideological and political actions, and unite and struggle for building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way. It is necessary to establish a people-centered work orientation, combine serving the people with guiding them to learn the Party’s innovative theory, grasp the theoretical concerns of the people, constantly innovate theoretical propaganda methods, and strive to make the Party’s innovative theory penetrate into the hearts of hundreds of millions of people and become a theory that is grounded, gathers people’s wisdom, conforms to the will of the people, and wins the hearts of the people, bringing together the majestic forces for building a socialist modern country and comprehensively promoting the great rejuvenation of the Chinese nation.

Mavic 3 family is a very important UAV product line in DJI, among which Mavic 3 and Mavic 3 Cine, the consumer flagship UAVs, were first unveiled, and then Mavic 3E and Mavic 3T, the small industrial UAVs, were released.

Next, we will bring the evaluation and introduction of DJI Mavic 3 Classic UAV.

Appearance: consistent with Mavic 3 family design

The design language of DJI Mavic 3 Classic is consistent with the Mavic 3 family, and the biggest difference is the modeling part of the image system.

Storage protective cover of DJI Mavic 3 Classic

Storage protective cover of DJI Mavic 3 Classic

DJI Mavic 3 Classic continues Mavic 3′ s storage protective cover design, which can protect the whole camera module, obstacle avoidance vision camera and bind the blades at the same time. With this storage protective cover, we don’t have to worry about damage even if we carry DJI Mavic 3 Classic alone.

It can be seen that the DJI Mavic 3 Classic still adopts the folding method, and the volume control of the storage is excellent, which is also convenient for us to travel and carry. After deployment, the fuselage of DJI Mavic 3 Classic is larger than that of Air Series, but thanks to its excellent configuration and aerodynamic design, the wind resistance of DJI Mavic 3 Classic is 35% lower than that of Mavic 2 Pro. This plays a vital role in improving endurance.

4/3 format Hasselblad camera of DJI Mavic 3 Classic

It can be seen that compared with DJI Mavic 3, the biggest difference of DJI Mavic 3 Classic is the design of the lens part. DJI Mavic 3 Classic cancels the telephoto lens design, improves the cost performance, and can better satisfy users who only want to experience the Hasselblad camera experience with ultra-high quality. The image system of DJI Mavic 3 Classic adopts a CMOS sensor design with 20 megapixels and 4/3 frames, which can shoot videos with the highest specifications of 5.1K 50P and 4K 120P, with a native dynamic range of 12.8 files, and supports Hasselblad Natural Color Solution (HNCS) and 10bit D-Log.

Cooling system of DJI Mavic 3 Classic

Cooling system of DJI Mavic 3 Classic

In order to achieve a better flight and aerial photography experience, DJI Mavic 3 Classic provides a large number of heat dissipation designs. At the top of the fuselage, there are large air inlets and fins at the head and tail. In particular, the design of a large-area heat dissipation area at the bottom of the fuselage can better help the drone to cool down during operation.

Safety blade of DJI Mavic 3 Classic

DJI Mavic 3 Classic also provides safety blades, which is consistent with Mavic 3 family. The safety blade is different from the previous UAV blades, and its end is made of plastic material (orange part), that is, the end of the blade is soft. DJI came to the conclusion through experiments that, even if the safety blade passes through an object during flight, it will generally only leave a scratch, and it will not be directly split. But even so, it is not recommended that you try, which may cause a bomber or your own safety hazards.

Card slot and interface of DJI Mavic 3 Classic

The card slot and interface of DJI Mavic 3 Classic are designed above the battery with a protective cover. DJI Mavic 3 Classic adopts USB-C interface and supports TF card (Micro SD card). At the same time, the drone itself has 8GB of body memory for emergency use.

Battery and charging housekeeper of DJI Mavic 3 Classic

Fast charging charger of DJI Mavic 3 Classic

The battery of DJI Mavic 3 Classic, like Mavic 3, has the capacity of 5000mAh and 77Wh, and the voltage is 15.4V. This battery provides the longest battery life of 46 minutes and the longest cruising range of up to 30 kilometers.

In addition, DJI Mavic 3 Classic is equipped with a GaN (gallium nitride) fast charging charger with a power of 65W, which is compatible with PD protocol. Besides charging the battery of DJI Mavic 3 Classic, it can also charge laptops, cameras and other devices.

Image system: 4/3 format Hasselblad camera is very powerful.

DJI Mavic 3 Classic inherits the design of this series of 4/3 format Hasselblad lenses, with 20 million pixels, equivalent to 24mm focal length and aperture range F2.8-F11. The 4/3 frame is what we often call M4/3 frame. However, in order to meet the take-off weight and size requirements of UAV, DJI and Hasselblad jointly developed a brand-new design.

That is to say, this lightweight and compact UAV lens can not only meet the requirements of image quality and resolution of 4/3 frames, but also meet the requirements of size, weight and power consumption required by DJI Mavic 3 Classic.

4/3 frame is the largest sensor size of consumer UAV at present. As the saying goes, the bottom is the first step to crush people. Thanks to the CMOS sensor with the bottom, DJI Mavic 3 Classic can bring excellent photography and video capabilities, not only better dynamic range performance, but also better color performance and resolution.

At the same time, in the dark environment, 4/3 frame can bring better noise suppression effect and make our dark video picture more pure. The newly added night video, cruise control and other functions can better serve users, so that users who have just stepped into photography can easily complete the shooting of various styles of videos.

The video specification of DJI Mavic 3 Classic also inherits the strength of Mavic 3 family, and supports the video specification of up to 5.1K 50P, and also supports the slow-motion video capture of 4K 120P. DJI Mavic 3 Classic supports 10-bit D-log, which provides a foundation for our later stage and color matching space. Supporting Hasselblad Natural Color Solution (HNCS) can make its color effect even better.

Through the video, we can easily understand the core competitiveness brought by the 4/3 format Hasselblad camera. Video is not only rich in details, but also remarkable in color expression, which can restore natural colors very accurately, as if it were the color appearance of the real world seen by our naked eyes.

In addition, the video itself has a dynamic range of 12.8 files, which is very helpful for later repair and adjustment. That is to say, with the help of DJI Mavic 3 Classic, we can shoot professional-grade videos, which can be used for video production in professional fields.

In terms of focusing, the experience effect of DJI Mavic 3 Classic is the same as that of DJI Mavic 3, and the focusing experience is excellent, just like we are using the camera’s focusing system. For users, it is more reassuring to hand over the focus to DJI Mavic 3 Classic to complete it by themselves.

In the photo section, we can see that the performance of DJI Mavic 3 Classic is still remarkable. After all, it is a 20-megapixel M4/3 format camera that can fly to the sky. 20 million pixels is close to the mainstream pixel specifications of the current camera, so the photos brought by DJI Mavic 3 Classic have delicate analytical performance, which can present the details clearly and completely.

The 12-bit RAW format file provides a very large space for our later period, which can make the photos more professional. When you encounter good scenery, you can use this 4/3 format Hasselblad camera to take pictures.

Obstacle avoidance: You can fly safely by avoiding obstacles in all directions.

When Mavic 3 in DJI was launched, an upgrade that surprised users was its obstacle avoidance system, and DJI Mavic 3 Classic completely inherited this obstacle avoidance capability. In other words, DJI Mavic 3 Classic supports omni-directional obstacle avoidance capability, which is the best performance of consumer drones in obstacle avoidance at present.

What is omni-directional obstacle avoidance, that is, DJI Mavic 3 Classic can sense the 360-degree spherical range of the whole body. We often say that up, down, front, back, left and right can avoid obstacles in these directions.

Forward-looking obstacle avoidance vision sensor of DJI Mavic 3 Classic

Up-looking and back-looking obstacle avoidance vision sensors of DJI Mavic 3 Classic

DJI Mavic 3 Classic’s down-looking obstacle avoidance vision sensor, ToF ranging sensor and fill light.

DJI Mavic 3 Classic has designed eight vision sensors, including two fisheye cameras at the front, back and bottom, which provide a 185-degree viewing angle and can cover a wider visual area. There are also two wide-angle cameras at the top of the fuselage, and there are ToF ranging sensors and fill lights below. Together, these designs provide powerful hardware support for obstacle avoidance vision.

In terms of software, DJI Mavic 3 Classic supports APAS 5.0 obstacle avoidance system. Thanks to the improvement of system algorithm, it can help DJI Mavic 3 Classic to avoid obstacles faster, more dexterous and smarter, and ensure the UAV to fly and take aerial photos safely.

When flying, DJI Mavic 3 Classic can identify obstacles and avoid obstacles by itself, even if it only makes the plane fly forward. We can choose emergency stop or detour in the menu, and detour can also choose safe or radical, which has achieved different results. No one will take corresponding measures to avoid obstacles according to our choice.

With excellent obstacle avoidance ability, it can bring excellent intelligent following ability to users. When we are outdoors, whether we let DJI Mavic 3 Classic follow our own walking and running shooting, or follow our own riding and driving shooting, we need the powerful following ability and obstacle avoidance ability of the drone to work together.

The overall performance of DJI Mavic 3 Classic is excellent. Because its obstacle avoidance system is smarter, it will have better path planning when following, and at the same time, its recognition ability is more stable, and it can keep up and keep up well.

Return flight: advanced intelligent return flight efficiency

DJI Mavic 3 Classic also has advanced intelligent return function. In the past, the unmanned aerial vehicle (UAV) was very unwise to return home. It needed to fly to a preset altitude, then fly back to the take-off point, and then descend. If you encounter a tall obstacle in the middle, you need to continue to climb the height and then cross the obstacle, which is time-consuming and electricity-consuming. Therefore, when we experience aerial photography, we will reserve enough power for the drone for returning flight. In this way, our experience time of aerial photography and flight will be greatly reduced.

DJI Mavic 3 Classic’s return flight ability is more intelligent and fully inherits the new skills of Mavic 3 family. During the flight, the visual processing engine of DJI Mavic 3 Classic can scan the surrounding environment in real time and build a three-dimensional environmental map. In this way, when returning, the drone will find a safe and efficient path to return.

If we return in the wild, the performance of DJI Mavic 3 Classic will not be particularly outstanding. After all, there are not too many obstacles in the wild to prevent us from returning. If you are returning in a city, especially in a city with many high-rise buildings, the intelligent return performance of DJI Mavic 3 Classic can be revealed. When encountering a tall obstacle, the drone does not climb or leap, but cleverly bypasses the obstacle and continues to return, which can save a lot of return time and electricity, and let us have more time to experience flying and aerial photography.

Image transmission: the picture is clear and stable.

The evaluation product we got this time is the remote control version of DJI Mavic 3 Classic RC, which means we got the remote control version with screen. However, both the remote controller DJI RC with screen and the remote controller DJI RC-N1 without screen have the same image transmission ability. DJI Mavic 3 Classic supports DJI O3+ image transmission, and can support the image transmission distance of up to 15 kilometers, and the transmitted images reach 1080P 60fps.

With this set of graphic transmission system, the experience of our daily use of DJI Mavic 3 Classic is directly improved. The first is the improvement of the picture transmission. The picture of 1080P 60fps is not only clear but also very smooth, which allows us to better view the flight picture and control the composition and flight. Although it is impossible to reach the image transmission distance of 15 kilometers in a city with serious interference, this image transmission system is still very stable and can ensure our safe flight experience. Even if it is disconnected, the plane can return intelligently, so don’t worry too much.

Endurance: 46 minutes can be a happy aerial photography.

The endurance of DJI Mavic 3 Classic is also 46 minutes, which is consistent with the products of Mavic 3 family. The test version we get will contain a battery itself, as well as two extra batteries in the battery pack and the charging housekeeper, which will ensure that we have a long flight experience and aerial photography time. At present, the 46-minute battery life ranks second among the consumer-grade UAVs in DJI, and the first one is the 47-minute battery life of the Mini 3 Pro with long battery life.

Battery and charging housekeeper of DJI Mavic 3 Classic

In the past, the average battery life of consumer-grade UAV products in DJI was around 31 minutes. Suppose we fly for 31 minutes, excluding the take-off, composition and adjustment time, which is about 10 minutes, and excluding the return time of about 6 minutes, our actual shooting time is only 15 minutes. The battery life of DJI Mavic 3 Classic is 46 minutes, so the actual shooting time can reach 30 minutes.

Summary: cost-effective flagship consumer drone

So far, our evaluation and introduction of DJI Mavic 3 Classic has come to an end. DJI Mavic 3 Classic has the same flying ability, obstacle avoidance ability, image transmission ability, endurance and so on as the consumer flagship drone DJI Mavic 3. At the same time, it also has a Hasselblad camera with 4/3 frame, which provides professional-grade imaging ability. The only difference is the telephoto camera. Of course, DJI Mavic 3 Classic has many functions that serve users, such as time-lapse photography, focus following, master shots, etc. Because these functions are completely consistent with the performance of Mavic 3, we will not repeat the test and introduction.

DJI Mavic 3 Classic is a differentiated Mavic 3 family member. Compared with the current Mavic 2 Pro and Air 2S, DJI Mavic 3 Classic has flagship flight and aerial photography capabilities, which can be described as a comprehensive upgrade, and the intensity of the upgrade is still qualitatively improved. At the same time, it has high cost performance and can fully meet the upgrade needs of users.

At the same time, based on the functions of Mavic 3 family, DJI Mavic 3 Classic has also added functions such as cruise control and night video, which allows users to achieve more diversified creations.

If you just need to upgrade and think that the price of Mavic 3 exceeds the budget, then the price of DJI Mavic 3 Classic is your best choice. Through our actual experience, this drone is enough to meet the use and shooting needs of professional users, both in flight capability and imaging system.

In particular, video creators, aerial enthusiasts, video teams and studios can fully consider this product because it is a flagship drone with high cost performance.

In the future, more new members will join in, enriching the category of consumer-grade flagship drones, and users can choose DJI drones that are more suitable for them according to their own needs and budgets.

　　Recently, mycoplasma infection and mycoplasma pneumonia have become high-frequency words in mom circle. Three years after the epidemic in COVID-19, before the arrival of mycoplasma infection, children have experienced several rounds of infectious diseases, which are influenza, syncytial virus infection, infectious diarrhea, herpetic angina and so on. From the beginning of school in March this year to the present, "one disease per month" children account for a considerable proportion.

　　The epidemic time of mycoplasma was advanced, and it spread widely.

　　During the epidemic in COVID-19, because everyone wears masks, washes hands frequently, keeps social distance, increases ventilation and disinfects more surfaces, children’s contact with other pathogens is reduced, and the incidence of virus and bacterial infections is reduced. However, everything has two sides. The decrease of infection makes the immune stimulation of pathogens insufficient, the susceptible population increases and the group immunity decreases. After reducing the intensity and scale of group protection in many countries, the incidence of respiratory syncytial virus and other pathogens increased significantly. In this context, experts put forward the concept of immune debt during COVID-19 (the above content was quoted from the No.1 issue of journal of applied clinical pediatrics Journal of China, Volume 38, January 2023, "Immune debt and its influence during the epidemic of children in novel coronavirus").

　　To put it simply, COVID-19’s three-year-old children may get one disease at a time. The flu hit first, and now it’s mycoplasma’s turn.

　　Mycoplasma is a prokaryotic microorganism similar to bacteria but without cell wall, which is between bacteria and viruses, smaller than bacteria and larger than viruses, and is the main pathogenic microorganism of respiratory tract infection. Most common mycoplasma epidemics occur in November and December every year, and this year is advanced to August and September, which affects a wider range of people. The children’s condition is biased and the course of disease is long.

　　Mycoplasma pneumonia has typical characteristics, and children should be vigilant in the following situations.

　　1. Severe irritating dry cough: Severe cough is a prominent symptom of this disease. At the beginning, it is a dry cough, and the cough is stubborn and severe. The child can’t stop coughing and even affect the activities during the day and sleep at night. Late sputum, cough is still severe.

　　2. Fever: high fever is common. If not treated, the fever will persist. There are also people with low body temperature or even no fever, which are relatively few.

　　3. Auscultation often does not hear rales: general doctors with lung infections can hear wet rales, but most of mycoplasma pneumonia can’t hear rales. The auscultation of the lung is very inconsistent with the clinical manifestations such as severe cough and high fever, which has become one of the characteristics of this disease. Therefore, the diagnosis of mycoplasma pneumonia often needs chest radiography to assist the diagnosis.

　　4. Chest X-ray: Typical mycoplasma pneumonia often shows large shadows in the lungs.

　　5. Routine blood test: Routine blood test of mycoplasma has no characteristics, unlike typical bacterial infection, where the total number of white blood cells, neutrophils and CRP are all increased, and unlike virus infection, which is basically normal, white blood cells are often normal or high, or one of them is high.

　　6. Mycoplasma pneumoniae antibody test: Mycoplasma antibody test positive can help diagnosis, but negative can not be excluded. And mycoplasma antibodies are often not detected at the early stage of the disease, which is not helpful for early diagnosis.

　　These are the characteristics of typical mycoplasma pneumonia, but actually not all mycoplasma pneumonia show these characteristics. Clinically, some children only have a high fever and their cough is not obvious. In the clinic, I once met a child who had a fever for 5 days, accompanied by a mild cough for 2 days, and a film was also pneumonia. Some children have no obvious fever, only moderate to low fever, and even have no fever but cough is very severe, and filming is also pneumonia.

　　About mycoplasma infection, these problems should be clear.

　　Will children get pneumonia if they are infected with mycoplasma? Mycoplasma pneumonia is very difficult, okay? Will there be sequelae? Parents have too many questions to answer.

　　First of all, it should be noted that infection with mycoplasma (mycoplasma pneumoniae) does not necessarily lead to pneumonia. Mycoplasma (mycoplasma pneumoniae) can not only cause pneumonia, but also cause upper respiratory tract infection (common cold symptoms) and tracheitis.

　　Which children are susceptible to mycoplasma (mycoplasma pneumoniae) infection? Mycoplasma pneumoniae mainly infects children aged 5-9, that is, school-age children. Recently, this wave of mycoplasma infection has spread to a wider age group, and infants also have severe mycoplasma pneumonia.

　　How to treat mycoplasma pneumonia? Once mycoplasma pneumonia is diagnosed, macrolide drugs such as erythromycin and azithromycin are given for treatment. Mycoplasma infection is not sensitive to penicillins and cephalosporins.

　　Why do children still progress to pneumonia after taking azithromycin? Is it delayed? Azithromycin is a specific drug for treating mycoplasma infection. Some children took azithromycin orally in the early stage of fever, but their condition was still getting worse and more serious pneumonia appeared. Parents often don’t quite understand why they developed pneumonia after taking azithromycin at the early stage of taking their children to see a doctor. The reason for this is complicated, which may be related to the variation or drug resistance of mycoplasma. It may also be related to the child’s poor rest after illness, or to the child’s physique.

　　Mycoplasma pneumonia is very difficult, okay? Will there be sequelae? Mycoplasma pneumonia has a good prognosis after regular treatment. However, there are also serious mycoplasma pneumonia, and the effect of antibiotic treatment is not ideal, so special drugs such as hormones are needed, and some need bronchoscopy to assist diagnosis and treatment.

　　If mycoplasma pneumonia is diagnosed, the child should be treated completely according to the doctor’s requirements, and hospitalization is needed if necessary. Have a good rest during and after the treatment, and don’t take classes with illness. After the treatment, you need a rest period.

　　How to prevent mycoplasma pneumonia? When the child is at school, the class should actively open the window for ventilation; Children should carry out appropriate physical activities to increase immunity; Don’t arrange extracurricular classes and physical classes too full, but step by step, so that children can have an adaptation process; Drink plenty of water, don’t eat too much, and ensure daily defecation. Daily ventilation should be ensured in the family. If children have mycoplasma infection, isolation should be implemented as much as possible to reduce cross-infection in the family.

Recently, the Inspection Bureau of the Taxation Bureau of Suzhou Industrial Park in State Taxation Administration of The People’s Republic of China investigated and dealt with the tax evasion case of Lisoft Information Technology (Suzhou) Co., Ltd. according to law. After investigation, in the absence of real business transactions, the company accepted 13 false VAT invoices and charged them before enterprise income tax, and enjoyed the preferential policies of small-scale and meager profit enterprise income tax in violation of regulations, paying less enterprise income tax of 782,700 yuan. In response to its illegal behavior, the Inspection Bureau of Suzhou Industrial Park Taxation Bureau made a decision to recover taxes, add late fees and impose a fine, totaling 1,775,700 yuan. At present, the taxes, late fees and fines involved have been recovered and put into storage.

Are 13 "coincidences" invoices true or false?

In the early stage, according to the clues of public security organs and the comprehensive analysis of tax big data, the Inspection Bureau of Suzhou Industrial Park Taxation Bureau found that 13 ordinary VAT invoices obtained by Lisoft Company were very suspicious. Three companies, such as Shanghai Yunyi Network Technology Co., Ltd., which are the issuers of invoices, were established within one week, and their invoicing time was the same day. The names of the invoices were all "* information technology services * software service fees", and two of them had the same registered address.

Upon further inspection, the inspectors found that the three billing parties were punished by the market supervision and management department for "stopping business for more than six months after opening" at almost the same time, and their business licenses were revoked two months later. This situation is obviously not a normal business state.

Did the three companies really provide "information technology services" to PowerSoft? Why is the invoice issued on the same day "exactly" after providing the service? After issuing the invoice, it is so coincidental to enter the "closed" state at the same time? Is this "coincidence" or "premeditated"?

After further analysis of the tax return of Power Soft Company by inspectors, it was found that the taxable income of corporate income tax in that year was 2,884,300 yuan. According to the relevant provisions of the preferential income tax policy for small and meager profit enterprises, "small and meager profit enterprises refer to enterprises engaged in industries that are not restricted or prohibited by the state, and at the same time meet the three conditions of annual taxable income not exceeding 3 million yuan, employees not exceeding 300, and total assets not exceeding 50 million yuan." Then, is there any artificial adjustment in the annual taxable income close to the "preferential limit" of Soft Power Company to defraud the preferential qualification? Are there real business transactions behind the 13 invoices? The inspectors can’t help but wonder.

Why are accounts payable for more than three years delayed?

Combined with the previous analysis, the inspectors interviewed the agent bookkeeping accountant of Lisoft Company according to law and asked him to provide relevant materials to cooperate with the inspection. Among the materials related to production and operation provided by the company, the inspectors did not find the business contracts signed with three billing parties, the project plan, operation and maintenance manual or user manual required for the information technology service shown in the invoice, and did not find any business-related communication supporting materials. Only invoices and accounting vouchers are not enough to prove the real existence of the business.

In order to further clarify the truth, the inspectors started with the flow of funds. The company’s accounting voucher shows that the total amount of the 13 fare issuance taxes is 1,200,100 yuan, which has been charged to the "accounts payable" account. At the same time, after checking the details of the company’s bank account, it is not found that it has paid any money to three billing parties. As of the time of inspection, the above-mentioned money for more than three years is still in the "unpaid" state. There are indications that the 13 invoices obtained by Power Soft Company are suspected of being falsely issued.

It is not worth the loss to enjoy tax incentives in violation of regulations.

The inspectors interviewed Li, the legal representative of Lisoft Company, according to legal procedures, and explained to him the relevant regulations on tax management, declaration and payment, financial accounting, tax collection and management, etc. In the face of complete evidence, Li had to admit that the company obtained these 13 ordinary VAT invoices by paying the "billing fee" without real business, and recorded them as "main business cost", which was illegally charged before enterprise income tax, thus reducing the taxable income to defraud the preferential qualification.

The company should have applied the corporate income tax rate of 25%, but in the reporting year, it violated the rules and enjoyed the preferential policies of small-scale and low-profit corporate income tax, that is, "the annual taxable income does not exceed 1 million yuan, and the corporate income tax is paid at the actual tax rate of 5%; The annual taxable income exceeds 1 million yuan but not more than 3 million yuan, and the enterprise income tax is paid at the actual tax rate of 10% (further reduced to 5% since 2022), in order to achieve the purpose of paying less enterprise income tax. However, this behavior has not escaped the investigation of the tax authorities in the end.

According to Article 12 of the Measures for the Administration of Pre-tax Deduction Vouchers for Enterprise Income Tax, invoices that are privately printed, forged, altered, voided, illegally obtained by the drawer, falsely made out, and filled out irregularly, and other external vouchers that are not in compliance with national laws, regulations and other relevant provisions shall not be used as pre-tax deduction vouchers. The false VAT invoice obtained by Power Soft Company belongs to the above-mentioned provisions, and the tax authorities accordingly require it to increase the taxable income by 1,200,100 yuan, and require it to pay back the enterprise income tax by 782,700 yuan according to law.

According to the first paragraph of Article 63 of the Tax Collection and Administration Law of People’s Republic of China (PRC), a taxpayer who forges, alters, conceals or destroys account books and vouchers without authorization, or lists more expenses or omits or omits income in the account books, or refuses to declare or makes false tax returns after being notified by the tax authorities, and fails to pay or underpays the tax payable is tax evasion. If a taxpayer evades taxes, the tax authorities shall recover the taxes and late fees that he fails to pay or underpays, and impose a fine of not less than 50% but not more than five times the taxes that he fails to pay or underpays; If a crime is constituted, criminal responsibility shall be investigated according to law.

According to the law, the Inspection Bureau of Suzhou Industrial Park Taxation Bureau made a decision to recover the tax, impose a late fee and impose a fine on the illegal acts of Power Soft Company. At the same time, the clues about the suspected false invoicing were transferred to the public security organs for further investigation.

On December 22nd, the Central Network Information Office held a video conference on the national network information system, and deployed the special action of "Clear, Combating Traffic Fraud, Black Public Relations and Network Water Army". Sheng Ronghua, deputy director of the Central Network Information Office and deputy director of the National Network Information Office, attended the meeting and delivered a speech. Responsible comrades of relevant departments of the Central Network Information Office and representatives of website platforms attended the meeting at the main venue, and responsible comrades of the Network Information Office of the Party Committee of all provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps attended the meeting at the sub-meeting.

The meeting pointed out that at present, the problems of traffic fraud, black public relations and network water army are interrelated and coordinated with each other, which damages the legitimate rights and interests of netizens, disrupts the network public opinion environment and undermines the market order of fair competition. The people deeply hate it and strongly reflect it. In this regard, the Central Network Information Office decided to launch a two-month nationwide special campaign of "Clear, Combating Traffic Fraud, Black Public Relations, and Network Water Army".

The meeting stressed that it is necessary to improve the political position and fully understand the significance of the special action from the aspects of standardizing the communication order, safeguarding the legitimate rights and interests of the people and maintaining a good market order. The meeting made it clear that this special action focused on traffic fraud, black public relations, and chaos in the network water army, focusing on three aspects of rectification tasks.The first is to control the traffic fraud problems such as brushing points, controlling comments, brushing letters, brushing the amount of powder, and brushing the list to canvass.Focus on platforms such as life service, book audio-visual scoring, social interaction and short videos, and focus on rectifying the fictional "notes on planting grass" and "online celebrity evaluation" by hiring professional writers and the network water army, or by "raising the number", occupying the front row of praise, and discouraging the deletion of bad reviews, etc., the film and television, songs, literary works, as well as commodities, food, and scenic spots are controlled and evaluated; Keep a close eye on commodity marketing links such as short videos, live broadcasts, and e-commerce platforms, and manage problems such as making false sales and false praise; Focus on social information, forum communities, live video, application stores, small programs and other platform links, rectify the purchase of fans in bulk, increase "zombie fans" and "talent powder", and organize the water army to create false readings, comments, reposts, likes, downloads, exposures and other issues; Pay close attention to the list positions of various website platforms such as "hot search list", "ranking list" and "popular recommendation", and seriously investigate and deal with problems such as malicious speculation and canvassing by manual or technical means.The second is to continue to rectify the chaos of online black public relations.Focus on cracking down on extortion of others and seeking improper benefits on the grounds of posting negative information on the Internet; Rectify and stir up social hotspots, concoct so-called "hot articles" and "explosions", and deliberately incite netizens to engage in malicious marketing; Centralized disposal of malicious counterfeiting, counterfeiting or misappropriation of information content published by organizations and other people’s accounts in order to attract attention or achieve the purpose of self-hype; Seriously investigate and deal with the problem that the website platform and related staff accept property and delete negative information for enterprises or individuals; Crack down on businesses fabricating negative or misleading information from competitors, systematically speculating and publishing, boosting the rising popularity, and harming the legitimate rights and interests of enterprises.The third is to resolutely investigate and deal with the information, accounts and related control platforms of the network water army.Comprehensively clean up a batch of information on promoting drainage or recruiting water army in the name of "network part-time job" and "recruiting writers"; Focus on investigating and dealing with a number of accounts of the water army registered in batches and publishing homogeneous information, which are used to create false data, stir up hot topics, attack and slander others, and sink negative information; Severely crack down on a number of group control software and hang-up platforms that provide brushing services.

The meeting demanded that cracking down on traffic fraud, black public relations, and chaos in the network water army is the final battle of the "Qinglang" series of special actions in 2021. It is necessary to strengthen organizational leadership, do a good job in supervision and implementation, grasp the work rules, compact responsibilities at all levels, pay attention to long-term governance, and promote the special rectification work to achieve solid results.

In the booming domestic electric vehicle market, there are many options for electric vehicles below 300,000, but when the price rises to 500,000, the selection range is relatively narrow.

500 thousand, buy an electric car, who will you think of?

Recently, I once again experienced the level of a 500,000-yuan electric car, yes, once again. When this car first came on the market, I was deeply impressed by the first test drive. It’s called EQE.

Modeling: elegance and exquisiteness coexist.

EQE still adopts a family-like front face design similar to EQS, but it is slightly different from EQS’s fashion pioneer sense. EQE’s shape takes care of the preferences of daily car users and is relatively more acceptable: the closed grille with the star emblem logo has a very high recognition, and the three-stage design surrounded by digital headlights and bottom makes the front face look more sporty; The 4.9-meter-long car and the 3.1-meter-long car body maintain smooth lines while ensuring enough space. The lower ground clearance and the two-color low wind resistance wheels further highlight the car’s sense of movement. The slip-back body shape and the duck tail design at the top of the rear trunk reflect the sporty atmosphere integrated with the whole vehicle in the roundness.

When you get into the car, you can clearly see that the old luxury enterprises have a unique understanding of luxury and intelligence. The overall layout of the car continues the design style of EQS, but it is different. 12.3-inch instrument screen, 12.8-inch central control screen, with exquisite walnut decorative board, the luxurious atmosphere is full at once.

Mercedes-Benz EQE is equipped with MBUX intelligent human-computer interaction system, which uses 8-core CPU, 24GB storage and 46.4GB memory bandwidth per second to ensure the fluency of the operating system. In addition, a group of physical buttons are reserved under the central control screen, including driving mode switching, parking images, EQ energy interface, etc., which can satisfy car owners who prefer the touch of physical buttons.

In terms of configuration, EQE is equipped with L2-level driver assistance component enhanced version, which integrates many driver assistance functions, such as intelligent navigation distance limiting function, intelligent navigation steering function, etc., and realizes the functions of full-screen display of navigation information, AR real-life navigation and 3D indoor map, realizing people-centered convenience, which is the scientific and technological concept that Mercedes-Benz EQE adheres to.

Driving: swiftness and comfort coexist

We can think about it with our eyes closed, and what is the battery life of mainstream electric vehicles now, ranging from 500 to 600 kilometers. Mercedes-Benz EQE is being developed based on the EVA platform, equipped with a power battery with a total capacity of 96.1kWh and NCM811 batteries, thus achieving a cruising range of up to 752 kilometers under CLTC conditions. At the same time, the car also supports a maximum of 128 kilowatts of DC charging, from 10% to 80% in 48 minutes.

EQE 350, which was put on the market in advance, uses a rear-drive permanent magnet synchronous motor, with a maximum power of 215kW and a peak torque of 556 N m. It only takes 6.7s to accelerate from 0 to 100 km/h, and the power consumption per 100 km is as low as 13.7kWh.

The first time I drove Mercedes EQS, I had a strong feeling that it was an electric car more suitable for "bosses" to drive themselves, although most of them would have their own full-time drivers. After two test drives of EQE, or out of a more compact body than the flagship EQS, I feel that this car is more suitable for driving by myself. Especially in the case of the blessing of technology such as active steering of rear wheels, this feeling will be more obvious.

In terms of power output, Mercedes-Benz EQE feels linear output in economy and comfort mode, relaxed but not impatient, and can experience the smoothness of driving while driving. When switching to sports mode, the power is abundant and the acceleration is very sensitive. But this sensitivity is also based on the "steady progress" and will not make you feel particularly abrupt. It feels like a large-displacement fuel car, and it is silky.

Mercedes-Benz EQE’s power steering and shock absorption adjustment are also very delicate. After a finely bumpy road section, the chassis adjustment of Mercedes-Benz EQE makes the car basically feel no vibration, while when passing through a large pothole road, the road feel will be clearer, but the front seats can absorb most of the shock. I deliberately chose some sections with continuous speed bumps to pass through many times, and even the photographer sitting straight in the back row did not feel too uncomfortable bumps.

Write at the end:

In the electric vehicle market segment of 500,000 yuan, EQE, which has the advantages of endurance and brand influence, is one of the "star" projects that will definitely be taken seriously. In this price range, who can choose without EQE?

Original title: "Test drive Mercedes-Benz EQE: 500,000-class luxury electric, who else can you choose if you don’t choose it? 》

On March 7 th, the progress of Tesla FSD (fully autonomous driving) has always been a point of great concern to the outside world. Now, more news about the landing of FSD Beta has been revealed. According to related news, Tesla FSD will land in the European market in 2025, and it is also advancing rapidly in China, and it is expected to be released this summer.

It is pointed out that the European Union adopted relevant new regulations at the just-held World Vehicle Regulations Coordination Forum, and according to this new regulation, it is confirmed that Tesla FSD European version will land in the European market in 2025, and in October this year, Tesla FSD Beta test will start testing in the European Union.

In China, the China version of Tesla FSD Beta is also advancing rapidly. It is reported that the goal is to be officially released this summer. In November last year, four ministries and commissions jointly issued a notice to deploy and carry out the pilot work of intelligent networked vehicle access and road traffic. At that time, Tesla FSD was considered to have entered the countdown stage.

Earlier, in May last year, Chen Kele, deputy director of the Intelligent Manufacturing Promotion Department of Shanghai Economic and Information Committee, said: In the next stage, Shanghai will further deepen its cooperation with Tesla, promote the layout of functional sectors such as autonomous driving and robots in Shanghai, and jointly build a technology industry cluster with core technological advantages and facing the global market. This also makes us believe that the landing of Tesla FSD in China is indeed just around the corner.

Tesla FSD, the full name of which is Full Self-Drive, means fully automatic driving. At present, Tesla has launched three assisted driving products, namely AP, EAP, and FSD, among which AP is the most basic and EAP is to enhance assisted driving, which can provide intelligent calling, automatic parking, NOA and other functions. These two functions can be used in China at present.

As Tesla’s highest-level assisted driving ability, FSD can provide navigation-assisted driving, automatic lane change, automatic parking, intelligent calling, traffic signal recognition and other functions. Up to now, only the Beta version has been provided in North America. But in fact, these capabilities are already possessed by major domestic new energy brands and have been used on the road. In this respect, Tesla is indeed a little behind. I believe that Tesla is also actively responding to ensure the early landing of FSD in China, which will also bring new revenue to it. We will continue to pay attention to this.

Since the beginning of this year, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the economic operation in the first quarter of the 14th Five-Year Plan has started well, showing the resilience and vitality of China’s economy. On April 23rd, State Taxation Administration of The People’s Republic of China released ten sets of tax data, which reflected that China’s economic operation in the first quarter showed a good trend of stability and consolidation.

According to the relevant person in charge of State Taxation Administration of The People’s Republic of China, there are two main reasons for the high growth rate of various indicators in the first quarter:On the one hand,In the first quarter of this year, the effectiveness of China’s overall epidemic prevention and control and economic and social development continued to show, a series of policy effects were continuously released, and the domestic and international market demand picked up. In addition, during the Spring Festival this year, many places advocated celebrating the New Year on the spot, and the employees’ arrival at their posts was significantly better than in previous years, which effectively promoted the accelerated production of enterprises and improved efficiency;On the other hand,In the first quarter of last year, affected by the epidemic, the base of various indicators was low, which brought about a higher increase in various indicators in the first quarter of this year. Therefore, to correctly read the economic situation in China in the first quarter, we should not only look at the year-on-year growth under the background of the epidemic in the first quarter of last year, but also look at the growth compared with the same period without the epidemic in the first quarter of 2019. On this basis, calculating the two-year average growth rate can reflect the economic operation situation more objectively and comprehensively.

First, the sales revenue of enterprises nationwide increased by an average of 12.8% in two years, and the production and operation of enterprises improved steadily.

General Secretary of the Supreme Leader stressed that it is necessary to promote enterprises to play a greater role in achieving greater development and to accumulate basic strength for economic development. The tax authorities have conscientiously implemented the arrangements of the CPC Central Committee and the State Council, implemented preferential policies for reducing taxes and fees through the implementation mechanism of the "one pole at a time" policy, vigorously promoted high-quality and efficient intelligent tax and fee services, and helped enterprises "travel light".

According to the data of VAT invoice, in the first quarter of 2021, the sales revenue of national enterprises increased by 50.5% year-on-year, 27.2% compared with the same period in 2019, and the average growth rate in two years was 12.8%, which continued the steady and good growth trend since the second half of last year.

Two, the national manufacturing sales revenue increased by 9.6% on average for two years, and the industry maintained a stable recovery trend.

Manufacturing is an important foundation of the real economy. General Secretary of the Supreme Leader has repeatedly emphasized the important role of manufacturing industry and clearly pointed out that efforts should be made to build a modern industrial system supported by advanced manufacturing industry. In the 2021 Government Work Report, Premier Li Keqiang proposed that the focus of economic development should be on the real economy and the proportion of manufacturing industry should be basically stable. Since the beginning of this year, a series of preferential tax and fee policies to support the development of manufacturing industry have been effective, which has effectively promoted the development of manufacturing industry.

According to the data of VAT invoice, in the first quarter of 2021, the national manufacturing sales revenue increased by 49.7% year-on-year, by 20.2% compared with the same period in 2019, and by 9.6% on average in two years. Among them, the equipment manufacturing industry increased by 59.7% year-on-year, with an average growth rate of 10.8% in two years, which was faster than the average level of manufacturing industry.

The rapid development of manufacturing industry has effectively stimulated the accelerated recovery of industry. According to the VAT invoice data, in the first quarter of 2021, the sales revenue of industrial enterprises nationwide increased by 46.7% year-on-year, 19.6% over the same period of 2019, and the average growth rate was 9.3% in two years. Among the 41 major industries, the average growth rate of 38 industries increased in two years, and the average growth rate of 18 industries exceeded 10% in two years.

Third, the sales revenue of high-tech industries increased by an average of 19% in two years, and innovation and development were accelerated.

The outline of the "14th Five-Year Plan" proposes to persist in innovation-driven development and comprehensively shape new development advantages.

Tanghe county Oilfield Base is a famous "barbecue street" in the local area. Many barbecue stalls have caused people’s disturbance, which makes the residents nearby miserable. In March this year, after receiving the feedback from the masses, the tanghe county Procuratorate immediately sent personnel to intervene in the investigation. After investigation, it was found that the restaurant in this street moved the barbecue stove out of the store for barbecue every night, and the stove did not take any measures to purify the oil smoke, and the smoke was directly discharged into the air.

In order to effectively solve the problem of open-air barbecue pollution, the hospital issued a pre-litigation procuratorial suggestion to the county urban management (law enforcement) bureau to urge it to perform its duties according to law. After receiving the procuratorial suggestions, the county urban management (law enforcement) bureau immediately investigated and standardized the management of open-air barbecues in fixed stores according to law, cleaned up and banned more than 60 illegal stalls for open-air barbecues, urged 507 catering units in urban areas to install fume purification facilities, and changed more than 210 barbecue stalls from carbon to gas and electricity.
