　　Jiangsu Provincial Health Security Bureau Jiangsu Provincial Health and Wellness Committee

　　August 6, 2021

　　Author: He Junming and Sun Huayu (both are special researchers of Socialism with Chinese characteristics Thought Research Center, the supreme leader of Fujian Province, and professors of Marxism College of Xiamen University of Technology).

　　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.

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.

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.

　　Xinhua News Agency, Beijing, May 17 (Xinhua News Agency) Comprehensive Xinhua News Agency reporters in Havana and Washington reported that the Cuban Foreign Ministry issued a statement on the 16th, saying that the US government’s announcement on the same day to relax some sanctions against Cuba was a "limited step" in the right direction, but the US has not changed its policy of blockade and "extreme pressure" on Cuba.

　　On the 16th, the State Council announced some adjustments to Cuba’s measures, including increasing the consular services of the US Embassy in Cuba and the number of visas for visiting the United States, simplifying the application procedures for American families to visit relatives in Cuba, canceling the quarterly remittance limit of US$ 1,000 to Cuban relatives, supporting the donation of remittances to Cuban entrepreneurs, and providing small loans and training support to Cuban private economic practitioners.

　　The Cuban Foreign Ministry responded that the measures against Cuba announced by the US government were "positive but the coverage was very limited". The United States has not lifted the long-term blockade against Cuba, nor has it removed Cuba from the list of "countries supporting terrorism", and still maintains most of the sanctions imposed on Cuba during the administration of former US President Trump.

　　The statement reiterated that the Cuban government is willing to conduct a respectful dialogue with the US government on the basis of equality without interfering in internal affairs and fully respecting independence and sovereignty.

　　After the victory of the Cuban revolution in 1959, the US government adopted a hostile policy towards Cuba. In 1961, the United States and Cuba broke off diplomatic relations. In 1962, then US President Kennedy officially announced the implementation of economic and financial blockade and trade embargo against Cuba. In 2015, the two countries resumed diplomatic relations, but the United States did not completely lift the ancient blockade. After the Trump administration took office in 2017, the United States once again tightened its policy toward Cuba and continuously upgraded its sanctions against Cuba.

　　Hangzhou announced today that on the basis of the previous first coupon, an additional 150 million yuan will be issued for the second coupon. The coupons for this issue will be distributed from 10: 00 am on April 3, and consumers can participate in the coupon collection activities from the entrance of Alipay homepage or by searching for "Hangzhou".

　　There are 1.5 million additional coupons for the second phase, each of which includes 3 coupons for 45 yuan, 35 yuan and 20 yuan. Direct deduction of cash use through Alipay when paying offline at designated merchants, valid for 7 days. Users who have received the first coupon can also apply again.

　　In the past few days, consumer vouchers have become the most popular keyword in Hangzhou except the epidemic, and they are also like a needle catalyst, igniting the enthusiasm of offline consumption in Hangzhou’s "post-epidemic era". In Hangzhou Century Lianhua No.1 Supermarket, the store was crowded with orderly consumers, and there was a long queue in front of the checkout counter. Ms. Wang, a citizen, received a coupon from 50 yuan the day before. "Milk, meat, eggs, and many daily necessities, most of them were originally bought. With the coupon, you can just buy more."

　　Wu Jingli of Century Lianhua Qingchun Store said that many customers come with coupons, and under the incentive of coupons, they can obviously feel the rebound of passenger flow.

　　It is reported that in the three days from March 27 to 29, the sales of Century Lianhua in Hangzhou exceeded 60 million yuan. "Coupons have boosted the sales of high-end aquatic products, beef, etc., and the increase in turnover is very obvious."

　　Snack bars, supermarkets, shopping malls, gas stations … … Consumer vouchers have boosted consumption, and they can be seen in almost every field of living consumption in Hangzhou. More than 10,000 pieces of Hangzhou "Xianfeng Fruit" were written off on March 27th, the first issue, and the customer unit price increased from 30 yuan to 70 yuan. Joe Doo, the person in charge of the operation, said that as of March 29th, their store had written off more than 30,000 copies.

　　Hangzhou Yonghui Supermarket also ushered in a business peak because of coupons. Jiang Yajing, head of Hangzhou regional brand of Yonghui Supermarket, said that after the issuance of consumer vouchers, the daily passenger flow of the supermarket exceeded 6,000, an increase of about 70% compared with last week. On the 27th, the number of customers who paid through Alipay transactions increased by nearly 100% compared with the previous day.

　　Consumer vouchers undoubtedly played the role of a catalyst, so that the consumption power that was originally suppressed by the epidemic rose rapidly. According to the data of Hangzhou Bureau of Commerce, from the issuance of the first coupon on March 27 to 16:30 on April 1, the government subsidy of 66.95 million yuan has been paid, driving Hangzhou to spend 949 million yuan.

　　Wang Jianming, dean of the School of Business Administration, Zhejiang University of Finance and Economics, believes that guiding the consumption direction, adjusting the consumption structure, and promoting the consumption upgrade, the "leverage effect" of consumer vouchers has achieved the greatest economic benefits in the most effective way.

　　Sun Hao, a teacher at the School of Economics of Zhejiang Gongshang University, also believes that the "multiplier effect" of the expansion of consumer vouchers will help to activate and release the consumer demand suppressed by the epidemic, boost consumption and promote the economy.

　　Since March, in addition to Hangzhou, governments in Guangxi, Nanjing, Hefei and other places have issued consumer vouchers through platforms such as Alipay. Jiaxing announced the issuance of 200 million yuan of consumer vouchers; Shaoxing will carry out nine consumption promotion actions and distribute 180 million yuan coupons to the public; Ningbo, county (city) governments and enterprises will jointly launch 100 million yuan of cultural and tourism vouchers for benefiting the people. The Zhejiang Provincial Department of Culture and Tourism said that through the linkage of provinces, cities and counties, a total of 1 billion yuan worth of travel coupons and 100 million yuan worth of travel coupons will be launched.

　　"Promotion fees and expanding domestic demand are a lasting battle." Many experts have reminded that as a short-term emergency policy and means, consumer vouchers have a certain effect on stimulating the economy, especially consumption, but they will not play a long-term role. To really stimulate domestic demand, only by enhancing residents’ consumption confidence and ability, increasing residents’ income and reducing the national burden, "comprehensive measures and stabilizing consumption expectations can people really consume, be willing to consume and dare to consume." (China Youth Daily, Hangzhou, April 2 nd, Zhongqing Daily, Zhongqing Net reporter Dong Bishui)

　　People’s Daily Online, Beijing, December 13 (Reporter Sun Hongli) Today, the joint prevention and control mechanism of the State Council held a press conference on health management of key populations and answered questions from reporters.

　　At the meeting, a reporter asked, some elderly people think that it is a little late to vaccinate COVID-19 vaccine. How long can I produce antibodies after vaccination?

　　In this regard, Wang Huaqing, chief expert of immunization program of China CDC, said that the elderly who have not completed vaccination should be vaccinated as soon as possible. It does take some time to have a protective effect after vaccination. Generally, it takes one to two weeks to produce antibodies after vaccination, but if a relatively high level of antibodies is to be produced, it will take about four weeks after full immunization. However, sometimes it is necessary to carry out intensive immunization. After intensive immunization, the time to produce antibodies is faster and shorter, and the level of antibodies produced is higher.

　　"Therefore, those who have not completed vaccination should be vaccinated as soon as possible, and those who have not completed strengthening should be strengthened as soon as possible, so as to play a better protective role." Wang Huaqing said.

　　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.

Starting from 2023, after the New Year, BYD will usher in a wave of collective new product release, and the price will be reduced. The former champion version and glory version have led the trend of the automobile industry throughout the year. This feeling of rushing away from friends is really tense, but we can also see BYD’s attitude as a new energy guide in China.

Recently, BYD launched a new car named e7, with an official guide price of 103,800-115,800 yuan and a limited time price of 98,800-110,800 yuan. BYD has Dynasty series models and ocean series models, but in fact, E series models are rarely concerned, because most of these cars are oriented to the field of online car rental, but it is these cars that are more outstanding in many aspects, and even can be called the king of cost performance.

The first is the space performance. The starting price is less than 100,000 yuan, but the length, width and height are 4,780/1,900/1,515 mm, and the wheelbase is 2820mm, so it is positioned as a medium-sized car. Compared with BYD and New Energy, it has more space, and it makes up for the product gap between Hehan series models. In addition, the endurance performance must be solid and reliable, and its CLTC pure electric cruising range is 450 km and 520 km, and the whole system comes standard with heat pump air conditioning. The top model also has driver’s seat heating and ventilation, and the central control adopts a 15.6-inch display to support OTA upgrade, navigation and voice control.

BYD e7 is not specially designed for the network car market, but this kind of cost-effective model is more suitable as a network car, and it is also more suitable for ordinary family users to choose. After all, it can bring more comfort to family members in terms of space performance. Even the online car rental market is actually a huge potential market. There are countless models competing in this market, but at the practical level, facing the mileage of hundreds of kilometers every day, everything about the products will be exposed, so the products in this market are more competitive, while BYD has been rushing to friends in various fields.

Accurate market positioning and rich product lines are also the key to BYD’s success. BYD has launched a variety of models for different market segments, from high-end luxury brand-looking, to cost-effective E-series, to mainstream dynasty and ocean series, covering all price ranges and consumer groups. Take e7 as an example, it is precisely positioned in the online car and sinking home market. By providing products that meet the needs of these two markets, it quickly opened up the market situation. In other market segments, BYD also launched models that meet the needs of consumers through in-depth market research and analysis, thus occupying a large share in the overall market.

AM mirror summary:

The listing of BYD e7 once again shows BYD’s strong market competitiveness and innovative ability. With its cost-effective product advantages, it is expected to achieve excellent results in these two market segments by accurately cutting into the network car and sinking the home market. BYD can continue to lead the development of the industry, thanks to its strong technology research and development strength, perfect industrial chain layout, accurate market positioning and good brand reputation. In China’s new energy industry, BYD has brought profound changes from market structure, technological innovation to industrial chain construction, and has become an important force to promote the development of China’s new energy automobile industry. It is believed that in the future, BYD will continue to maintain the spirit of innovation and enterprising, bring more high-quality new energy automobile products to consumers, and make greater contributions to the development of China’s new energy automobile industry.

　　Cctv newsAt present, the domestic epidemic situation is scattered at many points, and the number of imported cases continues to increase, which further increases the risk of imported epidemic situations outside Beijing and outside Beijing. Some close contacts, on the way back to Beijing by train, plane and other public transport, are close to or overlap with the seats of the confirmed cases, because they wear N95 masks regularly, don’t eat, walk less and talk less, and do personal protection all the time, and finally they are not infected. Protect yourself and protect your family.

　　The Beijing Center for Disease Control and Prevention reminded people returning to Beijing to raise their awareness of prevention and control and do a good job of personal protection on their way back to Beijing..

　　Before returning to Beijing

　　★　Personnel entering and returning to Beijing should strictly implement the epidemic prevention policy.Plan your trip in advance., minimize transit.

　　★　　Prepare enough protective materials such as masks and hand-washing-free disinfectants.

　　★　　It is not recommended to travel for people who feel unwell, especially those who have respiratory symptoms such as fever and cough. Especially for the elderly, pregnant women and special people with chronic diseases, it is recommended to ask professional doctors to evaluate their health before deciding whether to travel.

　　On the way back to Beijing

　　★　　Personal protection throughout the process.. Adhere to scientific and standardized measures to prevent and control the normalized epidemic situation, such as wearing masks, washing hands frequently, often ventilating, and keeping a safe social distance.

　　★　Cooperate with transportation departments such as railways, civil aviation, passenger transport, and road checkpoints, and strictly implement various prevention and control measures such as temperature measurement and code inspection and inspection of nucleic acid certificates in accordance with relevant regulations.

　　★　When waiting for a bus, try to wait in a well-ventilated space, and do not stay in a crowded, closed place with dirty air for a long time. Do a good job of personal protection.

　　★　　Pay attention to hand hygiene after using public facilities such as toilets and elevators.

　　★　　When taking airplanes, trains and other means of transportation,It is necessary to wear masks in a standardized way throughout the journey, minimize walking, reduce contact with others, and reduce the frequency of meals., reduce the risk of infection.

　　★　　When dining out, you should pay attention to eating at the wrong peak and choose a ventilated place to sit. Try to sit down at intervals or eat on the same side. When two or more people eat together, they should use public chopsticks and spoons.

　　After returning to Beijing

　　★　Those who enter and return to Beijing need to hold the negative nucleic acid certificate within 48 hours and the green code of "Beijing Health Treasure" to strictly abide by various epidemic prevention regulations.

　　★　Personnel returning to Beijing in risk areas should take the initiative to report to communities, units, hotels and other departments in a timely manner and cooperate with various epidemic prevention measures such as isolation observation, health monitoring and nucleic acid detection.

　　★　Carry out 3 days and 2 inspections.That is, one nucleic acid test is completed within 24 hours after arrival in Beijing, and the second nucleic acid test is completed within 72 hours after the interval of 24 hours.No dinner, no party or going to crowded places within 7 days.Do not visit relatives and friends, recommend online shopping, reduce going out before the negative result of nucleic acid test, and do personal protection when going out.

　　★　Pay close attention to the health of yourself and your family.Once you have symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell, diarrhea, etc., don’t buy medicine by yourself, don’t take public transportation, and seek medical treatment in time according to regulations.

[ITBEAR] Recently, the state’s support for the new energy automobile industry has continued to increase, and a series of policies and measures aimed at promoting the development of electrification, intelligence, networking and sharing (referred to as "new four modernizations") have been introduced one after another, injecting strong impetus into the market. Among them, the subsidy policy of automobile trade-in has become the focus of consumers’ attention, and its market effect is remarkable.

The positive signal recently released by the National Development and Reform Commission is even more exciting for consumers, and the national subsidy policy is expected to continue to be implemented in the future, which undoubtedly provides more expectations for consumers who are interested in buying cars. According to the relevant person in charge of the National Development and Reform Commission, the support for the "two new" policies will be further increased in the future, and a new round of large-scale equipment renewal and trade-in of consumer goods will be promoted, and the subsidy policy for trade-in in the automobile field will play an important role.

Major car companies actively responded to the call of the state and introduced preferential policies for car purchase in succession, in order to get a share of the dividend of the state subsidy policy. From the replacement subsidy policies introduced by Cadillac, Star Road Star Era and Volvo at Guangzhou Auto Show to the active participation of brands such as Wuling Automobile, the market competition has become increasingly fierce. Car companies attract consumers’ attention by increasing subsidy amount, optimizing car purchase process and improving service quality, and strive to stand out in the fierce market competition.

However, while enjoying the policy dividend, consumers also need to pay attention to the specific implementation details of relevant policies. Although the National Development and Reform Commission has clearly stated that the state subsidy policy will continue, the specific subsidy standards and rules have not yet been finalized. When consumers apply for subsidies, they also need to prepare car purchase invoices, driving licenses and other relevant supporting documents to ensure the smooth receipt of subsidies.

For consumers who have not yet bought a car, the continuation of the national subsidy policy is undoubtedly good news. They can pay close attention to the policy trends, understand the preferential activities of car companies, and plan the car purchase plan in advance, so as to buy a car at the right time and enjoy the benefits brought by the policy.
