……

What is geothermal?

Geothermal energy is heat energy from the interior of the earth. In recent years, with the continuous efforts of Chinese scientific and technical personnel, geothermal energy has made great progress in both the scope of exploitation and utilization and the breakthrough of technical depth.

How to distinguish different depths of geothermal energy?

200 meters is called shallow geothermal energy; 200 meters to 3000 meters, called hydrothermal geothermal energy, the temperature can reach about 100 degrees Celsius; At a depth of 3000 meters, there is a high-temperature rock mass, the temperature can exceed 180 degrees Celsius or even above 200 degrees Celsius, but there is no fluid in it or only a small amount of water. This high-temperature rock mass is called dry-hot rock.

Dry-hot rock VS hydrothermal geothermal energy

The temperature of dry-hot rocks is 70-80 degrees Celsius, or even more than 100 degrees Celsius. You can heat directly after changing the heat, so the efficiency will be higher. However, compared with hydrothermal geothermal energy, although the temperature of dry-hot rock is very high, there is no natural fluid, so it needs artificial injection of fluid to generate high-temperature water or steam, and then it can be used for power generation or heating.

Little knowledge:

What is the current situation of geothermal resources development and utilization in China?

China is one of the earliest countries to develop and utilize geothermal resources. According to records, as early as 2000 years ago, there was a custom of hot spring bathing in China. In the 20th century, many countries, including China, began to develop and utilize geothermal energy for heating and power generation on a large scale.

China is rich in geothermal resources, and more than 3,200 geothermal areas have been discovered. In the past 30 years, with the continuous breakthrough of exploration and mining technology, the exploitation and use of geothermal energy in China have also increased year by year. At present, the scale of direct utilization of geothermal energy in China has ranked first in the world for many years.

What are the advantages of geothermal energy compared with traditional energy sources?

Green and clean, compared with fossil energy, geothermal energy has no emission of carbon dioxide, sulfur dioxide and dust; Compared with renewable energy, it has wide distribution, large reserves, large scale and stability, and can be localized and distributed.

At present, the annual recoverable amount of shallow geothermal resources in China can reach 700 million tons of standard coal; Hydrothermal geothermal energy in the middle and deep layers, with an annual recoverable amount of more than 1.8 billion tons of standard coal; The annual reserves of dry-hot rocks are huge, and the annual recoverable amount reaches 8.6 trillion tons of standard coal.

In recent years, wind power photovoltaic has developed rapidly, mainly used for power generation, but the effective utilization time of wind power generation is from 2000 to 3000 hours a year, and the photoelectric time is about 1000 hours. But geothermal energy can reach 8000 hours in power generation.

At present, geothermal energy is mainly used directly. By the end of 2021, China’s geothermal heating area is about 1.33 billion square meters, replacing standard coal by nearly 38 million tons, which is equivalent to reducing carbon dioxide emissions by 100 million tons. Therefore, the effect of geothermal green carbon reduction is very significant.

How to use geothermal energy?

There are two kinds of geothermal utilization: geothermal power generation and direct utilization. People often say that hot spring bathing, heating and refrigeration belong to direct use. China’s direct utilization has reached 37% of the world’s direct utilization, ranking first in the world for many years.

According to the evaluation report of the World Energy Association, geothermal energy accounts for 66% of the global renewable energy, far exceeding solar energy and wind energy. Because geothermal energy is not affected by natural conditions such as seasonal climate and day and night, it can provide uninterrupted power supply, and its annual utilization rate is 5-8 times that of solar energy and wind energy.

Do "CT" for the earth, what are the magic points of geothermal technology?

At present, many oil field enterprises and geological and mineral enterprises have turned to the field of geothermal development, and after introducing oil drilling technology into the field of geothermal development, they have made important breakthroughs in the field of medium and deep geothermal development.

In the past, we mainly used shallow geothermal energy, because of shallow burial and relatively low technical content. If we want to take out geothermal energy in a wider range or deeper level, we need to overcome some difficulties and tackle key technical problems.

Where is the technical difficulty? Through geological research, researchers will face some difficulties in opening strata, finding horizons and drilling wells, just like "doing CT" for the earth.

If there is water underground, such as some underground caves, the greater the water volume and the higher the temperature, the more likely it is to collapse and leak during well drilling. In recent years, through the introduction of petroleum technology and tackling key problems, the well has been successfully drilled.

If you want to get heat, you need a medium, and the heat can’t come up by itself. You only have to pump up the hot water underground for heat exchange. After changing the heat, the hot water will become cold, and then the cold water will be re-injected into the original layer and heated. In this way, a cycle is formed, which is to take heat.

If there is no water underground, it is also necessary to drill a well to create a thermal storage space underground, which is similar to dry-hot rock, which is equivalent to taking heat without taking water. The future focus is on developing dry-hot rock.

A large rock mass is under the ground. If the well is drilled and a hole is used to inject cold water, the heating speed is too slow and the amount is not enough. If a space is created underground for fracturing, some cracks and cracks are pressed and the water is injected. After using space to heat the water, another well is pumped out. Because of the high temperature of rock mass, steam or steam-water mixture can be used for power generation and heating. The progress of technology has promoted the scale development.

In addition, the sandstone reservoir in the basin is very rich in resources in China, and its reserves are very large, but the problem is how to recharge. This sandstone formation has small pores. In order to ensure that the geothermal water can be safely returned to the original reservoir after being used up, technicians continue to tackle key problems and eliminate impurities, physical blockage and chemical blockage, so as to achieve sustainable utilization.

In what fields does geothermal work?

Besides hot springs and power generation, geothermal energy can also be used in agriculture. Low-temperature hot water can be used for agricultural planting. If the water quality meets the requirements, rice can be directly irrigated. In addition, it can also be used for the cultivation of flowers and special vegetables. In the Bohai Bay area on the southeast coast, it is also used for the cultivation of high value-added animals, and it is also used for thermal insulation with hot springs. In agricultural utilization, geothermal energy has been used to dry vegetables and peppers in Tianjin and Hebei.

Little knowledge:

What fruits and vegetables can be grown by geothermal energy in greenhouses?

Yunnan Midu cherry tomato digital agriculture characteristic advantage park, in 2022, the output of single cherry tomato in the park exceeded 5,000 tons, and the output value reached 110 million yuan.

Different from the traditional greenhouse, geothermal energy is being planned here to replace the traditional natural gas boiler heating, which is expected to reduce the cost by more than 30%. Using geothermal energy to heat agricultural greenhouses can ensure the temperature of greenhouses in winter, and realize the anti-seasonal growth of crops and the wintering of heat-loving plants.

In addition, geothermal energy will not produce any carbon dioxide emission, crops grow in the greenhouse, and disposable films used for agricultural production insulation and some pesticides and fertilizers needed to prevent pests and diseases are also reduced, thus realizing green production, low carbon and environmental protection, further reducing energy consumption and carbon emission, improving planting efficiency and helping energy conservation and emission reduction.

Geothermal energy, even refrigeration?

In fact, the reason for using heat energy for heating is very simple. However, it is estimated that many people can’t understand the "reverse operation" of geothermal cooling. Let me explain it to you. Geothermal cooling can be said from two aspects:

One is to use "shallow geothermal" to realize cooling. Shallow geothermal heating and cooling are widely used in our country, because shallow geothermal is basically 20 or 30 meters below the ground. Here is a constant temperature layer, and the temperature is basically close to the local annual average temperature.

For example, in Beijing, it is about 16 degrees Celsius more than 30 meters underground. As we all know, our household air conditioners are divided into indoor units and outdoor units. When cooling in summer, we are equivalent to discharging the hot air inside the house to the outside. However, as Beijing is particularly hot this summer, it is very difficult to discharge the heat when it reaches more than 40 degrees Celsius. The use of ground source heat pump is equivalent to burying the outdoor unit underground, which is only 16 degrees Celsius, and the temperature will automatically flow from high to low like water. Therefore, it will be easier to discharge the hot air in the house to 16 degrees Celsius, which is more efficient than our household air conditioner.

Second, the use of "hydrothermal geothermal" to achieve cooling, at present, there are some experimental applications in China, mainly in Guangdong, and there is no large-scale promotion. Although our country is very rich in resources, the temperature grade is basically low, which is suitable for heating and hot springs, but its temperature is lower in power generation or refrigeration. In the past, we said geothermal energy, which means heating, but now it can be directly used to provide cooling, which may have broken through the cognition of many of us, and this is also because of the changes brought about by our technological breakthrough.

Case: Xiongxian County-"Smoke-free City"

Take Xiong ‘an as an example. Around 2014, the whole Xiongxian county has become a "smoke-free city"-there is no coal boiler in the whole city, and the city uses geothermal heating. After the establishment of xiong’an new area in 2017, Xiong ‘an’s energy planning introduced the concept of "geothermal+",that is, geothermal plus a part of gas and a part of electricity.

This is because xiong’an new area is a main city, five sub-cities and many nodes. In the main city, the building density is relatively high. If geothermal energy is used, the drilling density can’t be satisfied. Therefore, adopting the "geothermal+"model not only makes full use of geothermal energy, but also saves natural gas and electricity, minimizing the use of this fossil energy and traditional energy.

The utilization of geothermal resources brings us life.

What direct changes have been brought about?

The most intuitive change is the improvement of the environment. As we all know, the smog in Beijing was very serious a few years ago, especially in the heating season. However, in recent years, the change from coal to electricity and gas, especially from coal to geothermal, has obvious effects on environmental improvement. First of all, there is no geothermal emission; Secondly, for ordinary people, the cost of geothermal heating is flat compared with before, and it is more environmentally friendly.

What is the impact of scientific and technological breakthroughs on the promotion of geothermal energy?

China is rich in geothermal resources, especially in the use of heating, and our technology is very mature. Then why have many places not used geothermal energy? Is it because there is no geothermal resource? Actually, it’s not.

Geothermal energy is the heat in the earth’s interior, so there is geothermal energy under the earth’s crust, but the difficulty of development and utilization is different in different places, some places are more difficult and some places are easier, which leads to the difference in cost. Then we need to solve this problem with scientific and technological research, reduce the cost, and turn the resources that we could not exploit before into exploitable resources, so that residents in these places can also use geothermal energy.

What are the difficulties in the popularization and application of geothermal energy?

Our country is rich in geothermal resources, but in fact, our current utilization is very small. First, because our current survey of resources is actually not in place. For the development of geothermal resources, we must find out where the geothermal energy is, so that we can effectively develop it. Second, some technical aspects need further breakthroughs. Third, for the further development of resources, in fact, we still have a certain gap with foreign countries. If we can take out deeper resources, we should make greater progress in the large-scale utilization of geothermal energy in our country.

Imagine:

Development and application of geothermal energy

What changes will the future bring to our lives?

How will the continuous development and application of geothermal energy change our life in the future? I believe this issue is also of concern to everyone.

Did you find out? Nowadays, the new residential area has higher and higher technology content and higher living comfort. In the future, as geothermal energy enters thousands of households, let’s imagine that after returning home, we can soak in a hot spring, which is comfortable to listen to. (In Xiong ‘an, some communities can be realized now! )

Heating in winter, the community is very clean, there is no such thing as dust and granulation, and then the temperature can ensure that we are very comfortable; Cooling in summer, there is no need to hang the outdoor unit outside, and there is no need to blow hot air. There is no air conditioner or wall-hung boiler in the living environment, and the pipes are all underground … We really realize green, clean, healthy, environmentally friendly and low-carbon.

With the continuous development of deep mining equipment and technology in China, China’s geothermal mining has been extended to 5000 meters underground, and its application scope is wider and its forms are more diversified. The direct utilization of geothermal power generation, geothermal heating, geothermal refrigeration and so on ranks first in the world for many years.

　　The reference news network reported on September 30 that foreign media said that the world’s most innovative university rankings show that European and American universities are still more competitive than their Asian counterparts in the fields of research and innovation and promotion of industrial and market applications.

　　According to a report on the website of Deutsche Welle Radio on September 28th, among the top 100 most innovative universities in the world published by Reuters in 2017, there are 51 universities in North America, 26 universities in Europe, 20 universities in Asia and 3 universities in the Middle East.

　　Stanford University won the championship again. Stanford University, located in the center of Silicon Valley in California, has always played a key role in the development of modern network technology. Many of its graduates have become founders of leading IT companies, such as Google, Intel and Hewlett-Packard. New technologies and ideas from Stanford are frequently cited in the global academic and industrial circles. This is also one of the criteria for measuring innovation in colleges and universities in this ranking.

　　Massachusetts Institute of Technology and Harvard University also ranked second and third again. Ranked fourth is the University of Pennsylvania. The University of Leuven in Belgium, which has a history of nearly 600 years, ranks fifth.

　　Among the top 20 innovative universities in Asia, there are two Korean universities, namely Korea Institute of Science and Technology (6th place) and Pohang University of Technology (14th place).

　　According to the report, three universities in China entered the top 100 list this year, namely Tsinghua, Peking University and Zhejiang University. Compared with last year, the rankings of these universities have made great progress. Tsinghua jumped 15 places, ranking 51; Peking University rose by 10 places, ranking 60th; Zhejiang University ranks among the top 100 for the first time, ranking 100th.

　　The analysis also pointed out that one of the reasons for the poor performance of Asian universities in general is the long-term lack of funds in Japanese universities. Universities are important scientific research centers in Japan, but they rely heavily on government funding. Japan’s economic growth has been stagnant and deflation has been as long as 20 years. The reduction of public funds invested in colleges and universities means the decline of innovation ability. There are 8 Japanese universities on this list, and the top ranked is the University of Tokyo, ranking 21st.

　　According to the report, seven universities in Germany have entered the top 100 innovative universities, including Munich University of Technology (40th), Erlangen-Nuremberg University (50th), Munich University (64), University of Freiburg (81), Free University of Berlin (86), University of Mainz (91) and Dresden University of Technology (97).

Two days ago, we took stock of several micro/small pure electric new cars that have been listed since 2022. On the one hand, these cars are likely to become passive choices among people in the "price increase tide", and on the other hand, because there are indeed many new products of two types during this period, we need to help you sort out their respective characteristics.

By the end of March and the beginning of April, with the delivery of Weilai ET7, the official listing of Zhiji L7 and the brand-new BYD Han series, medium and large pure electric cars have become a new focus in the market. I think apart from the exposure brought by the centralized listing of new cars, the Chinese people’s own preference for cars also determines that medium and large cars will be a brand, especially the flagship and benchmark of China brands, so extra attention will be paid.

Next, through this article, we will take stock of the large and medium-sized pure electric vehicles that are recently listed/delivered, already listed and planned to be listed in the future.

■　New delivery/listing group

Weilai ET7, starting price: 448-526,000 yuan.

Weilai ET7 made its debut at NIO Day in 2020. As Weilai’s first car product, this car has high hopes from enterprises, hoping that it can become a new growth point of performance, while Weilai’s users and fans are full of expectations for it, hoping that it can be a high-quality pure electric flagship car.

In terms of appearance design, Weilai ET7 not only adopts X-bar family design language, but also uses many settings that are more in line with cars. For example, the streamlined body makes Weilai ET7′ s drag coefficient only 0.208; A lower posture with a hatchback design can make it sharper and more sporty. Therefore, I always think that Weilai’s family-style design language is more effective in cars than in SUVs, and it is the same for ET7 and ET5.

Of course, Weilai ET7 also shows us the most recognizable features of the NT2.0 platform model, that is, the three "watchtowers" on the roof, which are equipped with ultra-long-range high-precision lidar and high-definition camera. The advantage of placing the sensor here is that it can monitor the situation around the vehicle more accurately from the driver’s perspective, and it can also make the monitoring range wider from a commanding position.

In the interior, the interior of Weilai ET7 looks very simple. From the front center console to the door, it is equipped with three layers of "sandwich" decorative boards, of which the top layer is made of Microfiber microfiber, the middle is karuun® renewable rattan wood, and the bottom layer is Nappa leather. Listening to the friends who have tested the Weilai ET7, they said that the three decorative boards are delicate and soft in touch, and they look fresh and elegant, and there is no smell.

Of course, Weilai’s classic borderless instrument panel, vertical central control panel and round NOMI will not be absent. As for the seat part, the small partner said that compared with SUV models such as ES8 and ES6, the front and rear seats of ET7 are more comfortable, especially the rear seats, which are friendly in both posture and cushion hardness.

In the configuration part, Weilai ET7 comes standard with 360 HD panoramic images, front and rear parking assistance radar, transparent chassis, dynamic wheel torque control system, curve assistance system and other functions in terms of safety.

In terms of comfort and convenience, ET7 is equipped with panoramic sunroof, intelligent frameless electric suction door, electric tailgate with induction opening function, double-layer silent glass in front and rear windows, steering wheel heating, 1 7.5W USB Type A interface, 3 60W USB Type C interfaces, heat pump air conditioning system, 14-way electric adjustment of front seats, heating/ventilation/massage function of two rows of seats, memory and easy access function of front seats, enhanced head-up display system, and central wireless charging.

In terms of intelligence, Weilai ET7 has two very interesting functions besides the relatively basic functions such as remote interconnection control, intelligent car search assistant, and NOMI vehicle-mounted artificial intelligence system. First of all, this car has an AR/VR panoramic immersion experience interface. On NIO Day in 2021, Li Bin announced that Weilai has jointly developed AR/VR glasses with its partners. In the future, passengers can enjoy the audio-visual entertainment function by wearing glasses in the car, and the effect is even better than a single passenger display screen.

In addition, thanks to the blessing of 33 high-performance sensing hardware and Weilai supercomputing platform, ET7 has a higher-level intelligent driving assistance capability, which makes it easy, safe and efficient for us to drive long-distance or park. However, it should be noted that the NAD automatic driving assistance system equipped with Weilai ET7 requires a monthly subscription to unlock the full function.

Finally, talking about power, Weilai ET7 is equipped with a dual-motor intelligent four-wheel drive system, with a comprehensive maximum output power of 480kW, a comprehensive peak torque of 850Nm, and an acceleration time of only 3.8s seconds per 100 kilometers. In the battery part, Weilai ET7 can adapt to three specifications. Under CLTC comprehensive working conditions, the cruising range of 75kWh battery pack can reach 480 to 550km；. 100kWh battery pack can reach 615 to 705km；; The battery pack of 150kWh can reach 1000km. At present, the battery pack delivered by Weilai ET7 can be assembled with the first two specifications, and the battery pack of 150kWh will be applied to ET7 in the fourth quarter of 2022.

Summary:On the whole, the face value of Weilai ET7 is not bad, the interior materials are sufficient, the intelligent and comfortable configuration is also rich, and the dynamic performance is fierce. I believe that if you have the opportunity to test drive, you will find it very good. However, its starting price of 448,000 yuan is not low compared with that of most competitors of the same level, but fortunately, Weilai has a car purchase plan of renting batteries separately, which can at least make 70,000 yuan into a long-term flow, and the mature system of replacing electricity and replenishing energy is also more efficient.

Zhiji L7 Pro, starting price: 408,800 yuan.

On March 29th, Zhiji Automobile announced that the official name of the first edition of Zhiji L7 mass production was Zhiji L7 Pro, and the price was 408,800 yuan. At the same time, the official also locked orders for the A-round orders and the Angel-round orders, and announced the complete rights and interests of these two orders. At this point, this large and medium-sized pure electric car, which began to accept reservations nearly a year ago, is finally officially listed.

What impressed me most about this car was the design of its front face, especially the two symmetrical "Sigma" daytime running lights with unique styles, which were very recognizable after lighting. In addition, the black area near the headlights is equipped with 2.6 million pixels of DLP light projection headlights, which can project rich images on the ground in front, while the taillights are composed of ISC streamer overlapping interactive lights with 5000 LED light sources. It is no exaggeration to say that Zhiji L7 is a "light player".

On the side of the car body, Zhiji L7 has a three-dimensional waistline extending from below the A-pillar to the taillights, but otherwise the overall shape is relatively round and smooth. In addition, although the tail of Zhiji L7 has some slight slip-back design, the rear suspension is relatively long and the slope of the roof is not obvious, so it looks like a more orthodox car.

In terms of size, the length, width and height of Zhiji L7 are 5098/1960/1485mm and the wheelbase is 3100 mm. Although it is slightly smaller than Weilai ET7, the wheelbase is 40mm more.

In the interior design, although Zhiji L7 doesn’t use complicated graphics like appearance, this super-long triple screen and the touch screen below not only have a full sense of science and technology, but also make the sense of ceremony burst. With their foil, even this flat-bottomed double-frame steering wheel is less dynamic and more sci-fi.

In addition, Zhiji L7 is also sincere in the materials used for work. For example, the decorative board is made of Como Lake solid wood certified by FSC, the seat is covered with semi-aniline leather from Bavaria, and the screen is made of AMOLED material. The resolution is as high as 2K, the PPI is 220, the number of speakers is 22, the power amplifier is 1120W, and the whole car is equipped with double-layer sound insulation glass.

In terms of configuration, in addition to the various "sound and light" and in-car configurations we just introduced, Zhiji L7 is also equipped with Carlog intelligent car camera system, which supports 180 ultra-wide angle 4K HD shooting; IM OS intelligent interactive system is built in the central control and passenger display screen; In terms of driving assistance, Zhiji L7 is equipped with IM AD intelligent driving system. Thanks to the support of as many as 30 high-performance hardware and high-computing chips, the vehicle has high-level assistance capabilities such as city navigation, high-speed navigation, vehicle call and parking service.

In the power part, Zhiji L7 adopts a dual-motor four-wheel drive power system, with a comprehensive maximum power of 425kW, a maximum peak torque of 725Nm, and an acceleration time of 3.87s per 100 kilometers. At the same time, it is matched with a 93kWh battery pack, and the maximum cruising range under CLTC conditions is 615km. At the same time, in terms of chassis, Zhiji L7 has been professionally adjusted by WAE Williams team, and the rear wheel has the ability of active steering, so that this large and medium-sized pure electric car can also have rich control fun.

Summary:Different from other new brands, Zhiji Automobile is unique in user rights and adopts the concept of similar investment and entrepreneurship. Therefore, Zhiji L7 has angel wheel rights in the pre-sale stage, and after the Pro version is launched, it will have A wheel rights. Although this setting is very interesting, it is easy to attract more people to pay attention to this car, but in the actual car selection process, we found it difficult to find other configurations beyond these rights, such as more supporting functions of seats, voice interaction ability, car applications, air conditioning system, etc. I hope that when the regular version of Zhiji L7 goes on the market on April 17th, a relatively complete configuration list can be published on online platforms such as official website.

Brand-new BYD Han EV series, starting price: 26.98-32.98 million yuan.

On April 11th, the brand-new BYD Han EV Creation Edition and Qian Shan Cui Limited Edition were officially launched, and the subsidized price range was 269,800 to 329,800 yuan. Compared with the previous generation of Han EV, the obvious change of the new car is the improvement of power output parameters and endurance, and there are also some changes in exterior interior design, body size and configuration.

In the power part, the new Han EV Genesis Edition strengthens the output performance of the front motor, with the maximum power of 180kW and the peak torque of 350Nm. Therefore, both the single-motor version and the dual-motor version could have been more powerful in performance, but interestingly, we found that the 100-kilometer acceleration time of the new Han EV Genesis Edition is exactly the same as that of the previous generation Han EV.

So where did this "energy" go? Perhaps it is used to improve the endurance, because the new Han EV can achieve the endurance (CLTC) of 610km to 715km only with the blade battery of 85.4kWh, even at the lowest level, it runs farther than the super-long endurance version of the previous generation Han EV, and the same type of products in the market often need to be equipped with 90 to 100kWh batteries to reach a similar level.

In addition, in terms of size, the new BYD Han EV is 15mm longer than the previous version, while the width, height and wheelbase remain the same. So although the new Han EV has become bigger, it is not obvious from the car body. However, on the other hand, the captain of 4995mm allows the brand-new Han EV to enter the market track with a captain of 5 meters, which narrows the gap with many flagship cars of new forces and enhances the competitiveness of the brand-new Han EV in the same market.

In the intelligent part, the new Han EV is mainly upgraded on DiPilot intelligent driver assistance system. The new car will be equipped with 22 sensing components, and at the same time, it will add functions such as highway driving assistance and emergency avoidance assistance, which can better provide accurate and efficient help for drivers.

In terms of intelligent cockpit, the new Han EV will come standard with DiLink 4.0 intelligent network connection system, as well as high-end configurations and functions such as 5G quick connection, dual-frequency positioning, four-tone voice interaction, HiFi-level customized Tanner audio, W-HUD head-up display, DMS fatigue driving warning system, etc., and at the same time support remote upgrade of OTA of the whole vehicle.

In the exterior part, my favorite design of the new Han EV is the tail, which is not only an elegant slip-back line, but also a set of taillights like Chinese knots. It is reported that it has a dynamic lighting effect, and the "Chinese knot" will have a shuttle texture when the vehicle starts, which is both sci-fi and full of ritual.

In the new Han EV series, there is also a limited edition of Qian Shan Cui, which not only has an exclusive green color scheme, but also has exclusive configurations and interior and exterior decoration kits such as high-grade suede seats, sports interior kits, UWB digital keys and high-performance stone green four-piston pliers. In terms of power, the power system of this model is the same as the "610KM four-wheel drive exclusive type" of the conventional Genesis version.

Summary:I understand that the newly listed Genesis Edition and Qian Shan Cui Limited Edition of Han EV are not the updated models of Han EV, but more like the advanced and customized versions of Han EV. In addition, in terms of price, although the overall price of the new car is more expensive than the conventional Han EV, it still has some advantages compared with competitors of the same level, so if you only want to spend less than 270,000 yuan to buy a medium-sized and large-sized pure electric car, the creation version of Han EV is worth considering.

Krypton ZEEKR 001, starting price: 299,000-368,000 yuan.

ZEEKR 001, as the first model of Krypton, has three versions, and the price range is 299,000 yuan to 368,000 yuan. In terms of design, as a hunting car, ZEEKR 001 is difficult to tell whether it is a car or an SUV, because it has obvious cross-border elements, such as a slender front and a thick hatchback. We can only know that it is a medium-sized and large-sized pure electric car through the official definition of "luxury hunting coupe". However, it is because of this appearance that it becomes the most "fierce" one in its class.

In terms of dimensions, the WE version of this model has a length, width and height of 4970/1999/1560mm and a wheelbase of 3005 mm.. In addition, the length, width and wheelbase of the YOU version are the same as those of the WE version, but the height of the body will be lower, and the parameter is 1548 mm.

In terms of power, ZEEKR 001 has two kinds of power options: double motor and single motor, in which the combined maximum power of double motor is 400kW, the peak torque is 768Nm, and the acceleration time of 100 kilometers is only 3.8 s; The single motor version has a maximum output power of 200kW, a peak torque of 384Nm and an acceleration time of 6.9s per 100 km. In terms of battery configuration, ZEEKR 001 has 100kWh and 86kWh battery packs to choose from, in which the cruising range of the single-motor version of NEDC can reach 712km, and the cruising range of the dual-motor version is 526km and 606km respectively.

The new car is equipped with ZEEKR AD intelligent driving assistance system, two high-performance 7nm intelligent driving chips, including seven 8-megapixel long-distance high-definition cameras, a 250m-m super-long sensing millimeter-wave radar, 12 short-range ultrasonic radars, four short-range high-definition cameras, two in-vehicle monitoring cameras, one outside-vehicle monitoring camera and one rear streaming media camera, which can better assist drivers to cope with various complicated road sections.

On March 23rd, Krypton officially pushed the official version of ZEEKR OS 2.0 to all users. The new version upgrade involves 33 ECU units, adding 5 functions, and upgrading and optimizing 59 functions according to the user feedback of Zeekr OS version 1.1.1.

The biggest highlight of this update is the first batch of open ZAD Krypton intelligent driving assistance system functions, including ACCQA adaptive cruise with queuing function, AEB forward collision mitigation, LDW lane departure warning, and FCTA front intersection warning function, which brings new intelligent security for users’ high-frequency application scenarios in daily driving.

In terms of configuration, ZEEKR 001 is equipped with frameless doors, electric tailgate with high memory, front seat heating, Microfiber microfiber ceiling, one-button reclining of rear seat, 360 HD panoramic image, transparent chassis, 14.7-inch WHUD head-up display system, AI Mate intelligent assistant, wireless charging of 15W mobile phone, face ID recognition, external discharge and other functions. The top is also equipped with high-performance air suspension set, intelligent induction automatic door, privacy glass, intelligent seat massage, YAMAHA surround sound advanced audio, intelligent constant temperature air conditioning and other functions as standard.

Summary:At the beginning, when Weilai ET7, Zhiji L7 and brand-new Han EV were not "born", the fastest medium and large car on the surface was ZEEKR 001 except Tesla’s Model S. When it comes to face value, ZEEKR 001 is highly recognizable by its maverick design. In addition, in terms of intelligence and configuration functions, ZEEKR 001 is full of sincerity, and even the top price of 368,000 yuan is actually quite high.

Extreme Fox Alpha S, starting price: 25.19-344,900 yuan.

Alfa S is a pure electric medium-sized and large-sized car officially launched by Extreme Fox in April 2021. At present, there are four versions officially listed, and the price range is 251,900 to 344,900 yuan. In addition, there is an Alfa S HI version, and the pre-sale prices of the two configurations are 388,900 yuan and 429,900 yuan respectively. The Alfa S is not only the second model of Extreme Fox, but also the first car product.

In terms of appearance, in fact, compared with the earlier SUV model Alfa T, the design of this Alfa S will give me a more traditional feeling, and it will not be too sharp in many details, whether it is the headlight with a drop-shaped front face, or the opening below, or the tail with a small slip back and the arc-shaped through taillights, there is a low-key and calm texture.

In terms of size, the body length, width and height of the polar fox Alpha S are 4930/1940/1599mm respectively, and the wheelbase is 2915mm；; The Alfa S HI version has a length, width and height of 4980/1960/1599mm, and the wheelbase is also 2915 mm. Judging from this wheelbase parameter and the relatively short front and rear suspension, the interior space performance of Alfa S is still good, which is definitely enough.

In terms of configuration, let’s first look at the regular version of Alpha S, which comes standard with α-Pilot assisted driving system, including ACC adaptive cruise, TJA traffic congestion assistance, ICA integrated cruise, CBC intelligent corner cruise, ASL intelligent speed limit cruise, RDP lane departure correction, LDW lane departure warning, remote driving and other functions. In addition, it also has a 20.3-inch 4K touch widescreen, wireless charging of 15W mobile phone with forgetting reminder, voiceprint recognition, α intelligent voice assistant with sound source localization and continuous dialogue, active air intake grille, electric tailgate, front seat heating and electric adjustment, and a wealth of in-vehicle applications.

On the HI version of Alpha S, we can see that the whole system is equipped with a very powerful intelligent driver assistance system. Not only is the chip computing power up to 400TOPS, but it is also equipped with 3 laser radars, 6 millimeter-wave radars, 12 ultrasonic radars, 9 ADS cameras and 4 panoramic cameras. Therefore, this model can realize the functions of intelligent driving assistance on expressways, intelligent driving assistance on urban roads, AVP parking service and vehicle summoning.

In addition, the HI version of Alpha S is also equipped with intelligent auxiliary functions such as 21.7-inch 4K ultra-clear central control panel, 8-inch HUD head-up display, human-computer interaction system capable of continuous dialogue, smart home control, smart gesture recognition, and intelligent driver behavior detection.

In the power part, the maximum output power of the conventional Alpha S single-motor precursor power system is 160kW and the peak torque is 360Nm；. The maximum output power of the dual-motor four-wheel drive power system is 320kW and the peak torque is 720Nm. The batteries matched with all models have two specifications, 67.3kWh and 93.6kWh, and the cruising range of different versions of NEDC under comprehensive working conditions is 525km, 708km and 603km respectively.

The Alfa S HI version is a four-wheel drive power system, with a comprehensive maximum output power of 473kW, a comprehensive peak torque of 655Nm and an acceleration time of 3.5s seconds per 100 kilometers. However, at present, the official has not announced the battery capacity and cruising range of this model, only that it is equipped with 750V fast charging technology, and it can get a maximum battery life of 197km after charging for 10 minutes.

Summary:Perhaps from the appearance and shape, the Alfa S series is a relatively "compact" model in the medium and large-sized pure electric car market, but after all, it has a length of more than 4.9m and a wheelbase of more than 2.9 m, so it is completely enough in space. In addition, the configuration of Alpha S series is also very rich, especially the standard configuration of the whole system is very kind, and the starting price is low, which is a good choice for friends with limited budget.

Zero run C01

On February 25th this year, Zero Run Automobile released a lot of information and a set of official renderings of its brand-new pure electric car Zero Run C01 for the first time. It is reported that the new car will be the first C-platform electric medium-sized and large-sized car with zero running, and the body length can reach 5 meters. At the same time, it is also the first mass production model equipped with CTC battery technology, with 3s-class 100-kilometer acceleration performance and 700km endurance. According to the official, the zero run C01 plan will be released in the second quarter of this year.

In terms of design, we can find many zero-run family-style design languages from the official map of the new car, such as the penetrating light strip on the front face, polygonal headlights and body lines. According to the official introduction, the zero-run C01 takes the natural aesthetics of science and technology as its design concept, and does subtraction in modeling and addition in experience. Taking "purity, intellectual interest and nature" as the key words, it abandons redundant modeling features and reduces the visual load, which is simply translated as "simplicity but not simplicity".

In terms of technology, the zero-run car summarizes four key information points of "1, 3, 5 and 7" for this new car.

"1" stands for zero-run C01, which is the first mass-produced vehicle with CTC technology. The so-called "CTC" is called "Cell To Chassis", which refers to the technology of integrated design of battery module and lower body. The biggest advantage of this technology is that the impact resistance of the battery and the torsional stiffness of the car body are greatly improved, and at the same time, the safety of the power battery and the whole car body is effectively guaranteed. At the same time, this technology can also help the zero-run C01 to have more spacious driving space, and at the same time make it have stronger handling and cruising range.

"3" means that the 0-100km/h acceleration time of the zero-run C01 can enter the 3-second class, which is the fastest acceleration of the domestic electric car of the same class. According to the official introduction, the zero-run C01 is equipped with a smarter power system and adopts a variable-structure oil-cooled electric drive, which not only has top-level quiet performance and driving efficiency, but also has a design life of more than 1 million kilometers. In addition, the reason why the new car can have such a "fierce" acceleration performance is because its body has a drag coefficient of 0.226Cd and the whole vehicle achieves 5% lightweight weight reduction.

"5" means that the body length of the zero-run C01 will reach 5 meters, so as to match the identity of the brand flagship car. In fact, the zero-run car has some experience in building a big car. The zero-run C11 has won the favor of the industry and consumers with its rare large wheelbase and large space at the same price. Therefore, we are not only full of imagination about the "figure" of the zero-run C01, but also full of expectations about its price range.

The last "7" means that the cruising range can reach 700km under the comprehensive working condition of zero run C01. It can have such "vitality", first of all, because it is equipped with a 90kWh ultra-large capacity power battery, and the battery adopts a penetrating large module scheme, which effectively improves the space utilization rate and structural strength. In addition, Zero Run also installed a big data AI intelligent battery management system for the new car, which can predict the future state of the battery more scientifically and efficiently, effectively extend the service life of the battery and improve the safety performance.

Summary:If the zero-run C01 is really as mass-produced as the information exposed at present, and the pricing strategy of the zero-run C11 "price butcher" can be continued, it will definitely be good news for consumers, because we have another "good quality and low price" medium and large-sized pure electric car to choose from, so friends who plan to buy the medium and large-sized pure electric car in the second half of this year or for a long time, I suggest "squatting" the zero-run C01. For other brands in the same class, the zero-run C01 is an opponent that absolutely needs to be vigilant, especially the models priced at around 250,000 to 300,000, which may suffer a direct impact.

Mercedes EQE

In the "Announcement of Road Motor Vehicle Manufacturers and Products" issued by the Ministry of Industry and Information Technology in February, we saw the new car application information of the domestic Mercedes-Benz EQE. It is reported that this model was introduced to China by Beijing Benz Automobile Co., Ltd.

Judging from the new car declaration map, the appearance of the domestic version of EQE basically continues the design of the overseas version. The family-style language makes it like a miniature version of EQS, with a dot-matrix closed plaque on the front face, headlights with rising corners of the eyes, and "X" shape. Surrounded by the front, it creates a gas field that is not angry and arrogant.

Looking at the side again, although Mercedes-Benz EQE adopts the same arch body design as the big brother EQS, the lines are not so extreme, and the sliding back and the downward direction of the window are softer. In addition, the new car adopts hidden B and C columns, chrome-plated frames are assembled around the windows, and the wheels also adopt five sets of double-banner lattice closed rims, which looks very advanced as a whole.

However, from the back, Mercedes-Benz EQE presents a more sporty style, especially the high-position brake lights, small tail wings and the rear surrounding shapes are very dynamic. In addition, the new car, like EQS, is equipped with arc-shaped through taillights, and the brake light source is expected to be similar to spiral ribbons.

In terms of parameters, the application information shows that the length, width and height of the domestic version of Mercedes-Benz EQE are 4969/1906/1509mm and the wheelbase is 3120mm respectively. The tires have three specifications: 235/50 R19, 255/45 R19 and 255/40 R20. The power system is equipped with a drive motor with rated power of 100kW and peak power of 215kW, and the maximum speed is 180 km/h.

In addition, according to the declared information of optional accessories, the front and rear bumpers, front grille, exterior rearview mirrors, rims, side skirts, headlights, tail signs and door frame decorative strips of domestic Mercedes-Benz EQE will have different changes.

Summary:Did you find out that Mercedes-Benz EQE is the only medium-sized and large-sized pure electric car with a traditional luxury brand among the models we counted this time, and it will take the lead in entering this market segment as the "vanguard" of BBA. However, with these large and medium-sized pure electric cars of China brand in the front, it’s hard to say whether people will have an "impulse" on Mercedes-Benz EQE. It must come up with something different to prove that it is worth having.

Mechanosaurus, the limited edition price is 488,000 yuan.

If ZEEKR 001 is a hunting coupe more like a beast, then the Mechelosaurus from Salon Automobile is a high-performance coupe with the style of hard-core mecha.

In terms of appearance, the Mechelon is a quite large four-door GT model from the side. It is reported that the length of this car will reach at least 5 square meters, even the size of a large car. In addition, the window with hidden B/C pillar and through waistline make the car look slimmer visually. At the same time, all kinds of broken lines and protruding wheel eyebrows on the car body make this car full of muscle.

Of course, if we only look at the front face, the mecha dragon is more like a violent modified performance car, especially the angular headlights and the simple folding design of the body, as well as the very three-dimensional front surround, which brings us a stronger impact.

In the interior design, the front row of the mecha dragon, especially the main driving area, has a strong fighter style, and even the inner side of the steering wheel rim has a three-dimensional polygonal design, which can be said to be very rough. However, coarseness does not mean coarseness. Judging from the current official renderings, the interior layout of the Mechanosaurus is very regular, the components are carefully assembled, and the materials used should not be bad.

Oh, by the way, there is also an official name for the cockpit of the Mechanon, which is called "Source Code" Mecha Intelligent Control Cabin. This is because it is equipped with Qualcomm 8155 high-performance chip with 8 cores and 7 nanometers process, and has DMS+OMS dual in-car cameras, 4 independent sound zones and 5 interactive display screens, namely, 10.25-inch intelligent interactive screen, 27-inch 4K W-HUD integrated screen and 25-inch W-.

In addition, there are many luxurious configurations of this car, such as Harman Kardon’s 16-speaker 5.1-channel audio system, Nappa leather seat capable of 16-way electric adjustment and 8-point physical therapy pneumatic massage, and five-level noise control quiet system.

In the power part, the Mechanon adopts a front and rear dual-motor four-wheel drive system, with a comprehensive maximum output of 400kW and a peak torque of 750N·m, and the acceleration time of 100 kilometers is only 3.7 seconds. In addition, the Mechanon will become the first vehicle equipped with the Great Wall Dayu battery, and its capacity will reach 115kWh, and the CLTC will last 802km. Under the overcharge of 800V/480kW, it will be recharged for 401km in 10 minutes.

In terms of driving assistance, the Mechelosaurus is equipped with a captain’s intelligent driving system called "Captain-Pilot", which has intelligent driving assistance on high-speed and urban roads, and can also park automatically and remotely. There are as many as 38 intelligent sensing components serving this system, including 4 laser radars, 7 8-megapixel cameras, 4 panoramic cameras, 5 millimeter-wave radars, etc. At the same time, it adopts a dual DMC intelligent driving computing platform, with NPU computing power reaching 400 TOPS and CPU computing power reaching 400K DMIPS, which not only has dual redundancy, but also has independent MCU security monitoring.

Summary:When Mechelon was unveiled at Guangzhou Auto Show last year, it announced that the price of 101 limited-edition cars was 488,000 yuan. To be honest, this price is above average in the current large-scale pure electric cars, which is a little expensive, but it is not artificially high in combination with the current exposure configuration. In addition, this price is only a limited edition, and it may be slightly cheaper after mass production. On the other hand, the overall quality of Mechanosaurus is good, but its appearance is really radical, which may become the winner of the new car market performance.

I don’t know if you will feel this way. In recent years, it seems that the China market is already dominated by SUVs, whether from the investment in R&D of enterprises or the quantity and speed of new cars on the market. Even when domestic SUV models were just emerging, it was predicted inside and outside the industry that SUVs would soon replace cars and become the "cake" with the largest market share.

However, until now, there are still no "dry-turned" cars in SUVs. In the 2021 retail sales released by the Association, the annual sales volume of cars was 9.846 million, up 6.4% year-on-year, while the annual sales volume of SUVs was 9.221 million, up 3.0% year-on-year. In other words, not only did cars still have more shares than SUVs last year, but even their growth status was better than the latter.

Therefore, although SUV models are constantly "growing taller", the car market is still more "strong". In China’s new energy vehicle market, both cars and SUVs are "growing from scratch", but more consumers are still willing to buy new energy cars.

Therefore, for car companies, with the increasingly fierce competition, the new energy car market will inevitably be more subdivided, and there is still a lot of room in the medium and large car market, which is a "site" worth seizing. For consumers, the competition between brands means that we can have the opportunity to "buy a car up" with a lower budget, so if you have plans to buy a new energy vehicle of about 250,000 this year, you can pay attention to the medium and large pure electric car market. As for the current models, I recommend the brand-new BYD Han EV that has been listed, and those that have not been listed can focus on the zero-run C01.

The scene of Shanghai rushing to help Hubei medical team gather and pledge to go out in danger, and the working conditions of Shanghai medical workers in key cities such as Wuhan; The responsibility of the frontline staff of Shanghai’s anti-epidemic in the open city, the grace and love of the anti-epidemic volunteers … What kind of picture will the images that have touched countless people in the past two months be put into the artist’s pen?

On April 8,"Call-Shanghai Art and Photography Theme Exhibition for Fighting COVID-19 Epidemic"When the Chinese Art Palace opened in Shanghai, there was no opening ceremony for the exhibition, but on the first day of the opening, a group of special audiences were welcomed-some members of the Shanghai medical aid team who lifted the 14-day medical isolation. They visited the exhibition under the guidance of the Shanghai Federation of Literary and Art Circles, and the images in the works of art were their personal experiences not long ago.

Jerry Lee, the commentator of the Federation of Literary and Art Circles, tells the story in the picture to the members of the Shanghai medical aid team in Hubei.

"Call-Shanghai Art and Photography Exhibition for Fighting COVID-19 Epidemic" is the first large-scale physical exhibition in Shanghai with the theme of fighting COVID-19 epidemic. This exhibition has more than 800 works. Apart from art and photography, it also organically integrates folk art, calligraphy, sculpture, installation, poetry, video and other literary forms. All the works are original new works, and more than 80% of them are made public for the first time.

Members of the Shanghai medical team (first from left) can’t help but raise their cameras when they see the people in the painting, and think of the scene when they "went out to war".

The exhibition is divided into five parts: the main exhibition and the supplementary exhibitions of photography and comics. In the five parts of the main exhibition, there are not only works showing the various stages and processes of the war "epidemic" with time as the main line, but also scenes showing the war "epidemic" with space as the center. The photographic attachment "Unforgettable Moment" takes "Moment" as the key word to freeze the fleeting touching pictures in the process of "epidemic".

Exhibition entrance

Huge art collective creation, panoramic reproduction of anti-epidemic group images

Walking to the five-meter exhibition hall of the Chinese Art Palace, the first thing you see is a huge masterpiece "Call" with a width of 18 meters and a height of 2.2 meters. This is a huge art comprehensive material work jointly created by the Shanghai Artists Association. More than 20 artists work day and night, every 6 meters, and are divided into three groups to create collectively in one week. This is also the largest collective art creation with the theme of fighting epidemic in China, which reproduces the frontline people fighting epidemic in a panoramic way.

Dramatically create "Call" (partial)

A closer look at this huge work shows the most ordinary people around us, including medical workers, construction workers who built Raytheon Mountain Fire Mountain, courier brothers who stick to their posts and community volunteers. After a closer look, there are some familiar touching plots, such as "the little boy wearing Messi jerseys", "getting a haircut in front of the protest line", "volunteers who deliver food to medical staff every day" and "the mountains and rivers are on the same day" in aid materials. Under special circumstances, the people in the painting have also become the heroes and the most lovely people in everyone’s hearts, precisely because they persist in creating extraordinary things. The artists who participated in the creation also said, "This unprecedented experience has made us more cohesive and empathetic, and ordinary life is so precious."

On the left-hand side of the exhibition hall, the large-scale freehand landscape comes from Wang Jiafang, executive director of Shanghai Artists Association and painter of China Painting Academy. In the context of "war and epidemic", the painter linked the landmark landscapes of Wuhan, Shanghai and even the whole country across time and space by montage. In the picture, the Bund in Shanghai echoes the two clock towers in Jianghan Pass in Wuhan, which seems to indicate this unusual year of 2020.

Wang Jiafang’s "Wei Wei China Qing" at the exhibition site

On the edge of this 5-meter-by-3.2-meter freehand brushwork landscape, there is the only calligraphy work in the exhibition, and it is equally huge. This work was written by Zhang Feng, a young calligrapher in Shanghai, for 18 hours in a row. The famous calligrapher Han Tianheng paid tribute to the 1649 heroes in the Hero List by introducing the first chapter "Doctors are kind". It is reported that after the exhibition, this huge calligraphy work will be presented to the Shanghai Hospital in Hubei Province for collection.

Members of the Shanghai Medical Team for Aid to Hubei took a group photo pointing to their names in the calligraphy "Heroes List of Shanghai Supporting Hubei Medical Staff".

In addition, Li Shoubai, the chairman of Shanghai Folk Writers and Artists Association, has recently created a special four-part painting "Centripetal Force, China Power" which combines paper-cutting and oil painting, and the oil painting "Retrograde" created by Shanghai young painter Luo Lingjun, which is four meters high and stands tall, showing the action of a retrograde dressed in protective clothing, which seems to indicate that he is about to join the battle at any time.

Jin Wenyi, an exhibiting artist, introduced that his works were originally used as a diary of creation in a special period. At that time, he saw a medical staff wearing airtight protection and his goggles were covered with sweat. At that time, he was very moved to see this photo, and his paintings were also based on it.

Artist Jin Wenyi (right 1) introduces his works.

Luo Lingjun’s oil painting Retrograde is at the exhibition site.

There is also an installation work in the exhibition, which comes from the artist Ding She. This work made of steel wire is called "Cover". As the name implies, the artist expresses a mask. "Masks are still in short supply, so when I was creating, I invited my friends to weave nearly 600 masks with metal materials. In addition to expressing the meaning of mutual links, the metal texture also made the works show a sense of strength." Ding she said.

Small works show the daily life.

In an unobtrusive corner of this exhibition, there is a small piece of "online celebrity" by Gan Feng, whose other name is better known-Murong Yindao. This work, which originated from the traditional gatekeeper, became the "gatekeeper" in the circle of friends in the Spring Festival of 2020. Huo Qubing more than 2,000 years ago and Xin Qiji more than 800 years ago have a new meaning here. This work was created on the day before New Year’s Eve, and Murong Yindao also hopes that the homophonic sound of "Huo Qubing and Xin Qiji" can dispel the bad epidemic.

Gan Feng (Murong Yindao)’ s work "Going to the Sick and Happiness" is in the corner of the exhibition hall.

There are also some small peasant paintings in the exhibition that simply and directly express the current platform. Among them, Cao Xiuwen’s "Uniting as One" and Ji Fang’s "Keeping the Epidemic Prevention Gate", the non-genetic inheritors of Jinshan peasant paintings, not only maintain the unique charm of peasant paintings with exaggerated art, novel conception, bright colors and elegant shape, but also express the prevention and control measures such as temperature monitoring and guarding in daily life in combination with hot spots.

Jinshan peasant paintings, Cao Xiuwen’s "Uniting as One" (upper right) and Ji Fang’s "Keeping the Epidemic Prevention Gate" (lower right)

In artistic creation, some small works with the same theme can often constitute a big creation. Among them, the young painter Xu Xufeng’s work "Together" belongs to this type. The author presents the daily state of 30 masks with 30 small works. His creative inspiration comes from different types of masks used by friends every day, while the background words mainly come from messages from all parties.

Xu Xufeng’s "Together"

In the same type of creation, some home themes focus on every day of life, and artists faithfully record every bit of life, as well as utensils and food.

Zhang Peicheng’s Life Guard

During the epidemic, a large number of works on the theme of medical staff also emerged. How to draw one’s own language and sincerity is not easy for artists, but the works of old artists may be enlightening. Chen Jialong, an artist in his 70s, watches the news every day to understand the trends ahead. He combines computer synthesis with Chinese painting to create cross-border works. Although it is wrapped in layers of protective clothing, the gentle eyes of the doctor in the picture bring the patient the greatest comfort and confidence. Ruimin Qiu, an oil painter, focused on the treatment of protective clothing for medical staff when his face only showed his eyes. He used a pen to summarize decisiveness, bold colors and a sense of decisiveness, determination and responsibility.

Chen jialong’s "The Magic in White Will Win the Battle"

Ruimin Qiu’s "The Cutest Man"

Advocate peak-shifting exhibitions and focus on online and offline exhibitions.

"More than 800 works exhibited in this theme exhibition were selected from more than 13,000 visual art works. Why can an anti-epidemic exhibition be organized after more than two months, among which the network initiative is indispensable. " Ding She, Deputy Secretary-General of Shanghai Artists Association,

On New Year’s Eve, Shanghai Artists Association, Photographers Association and Folk Writers Association released creative initiatives through the Internet. Among them, thousands of painters of comics, printmaking, traditional Chinese painting and oil painting responded positively, creating more than 1,000 works and pushing 25 issues online. Shanghai photographers, a group of first-line medical workers and volunteers have used cameras and mobile phones to take pictures of people and things around them, creating more than 10,000 photographs and pushing them online for 31 issues. The exhibits of this theme exhibition are the results of re-collection and re-launch on the basis of previous online collection and according to the exhibition hall characteristics and exhibition curatorial plan of China Art Palace.

Exhibition site

In addition to paintings and photographs, the exhibition also focuses on the multimedia theme works newly created by Shanghai literary and art circles, such as the four-grid comic book anti-epidemic story image, the eight-episode video of "The Paper" anti-epidemic first line, SMG anti-epidemic documentary, and various art categories such as "cloud creation", "cloud performance" and "cloud display". These works represent every author’s heart, and they are true, sincere and sincere, condensing every author’s emotions, enthusiasm, enthusiasm and love, providing spiritual comfort for people who are worried and conveying warm power for people who persist in fighting.

The exhibition shows the "video story collection" of media reporters and photographers.

At the same time, Shanghai Federation of Literary and Art Circles Media Center and China Art Palace will also open online exhibition halls for online display, as a supplement and extension of the exhibition. In the special period of epidemic prevention and anti-epidemic, you can enjoy wonderful works without leaving home.

Li Geye’s Guardian Angel

The postscript of the exhibition is also a cross-border work-the poem "Looking Back in Spring", which expresses the warm spring returning home as scheduled, and the poem of life is continuing to write endless chapters, and also looks forward to the early end of the global epidemic and the early return of a better life.

It is reported that this exhibition is co-sponsored by Shanghai Culture and Tourism Bureau, Shanghai Federation of Literary and Art Circles, Shanghai Health and Wellness Committee and Jiefang Daily, and jointly organized by Shanghai Artists Association, Shanghai Photographers Association, Shanghai Folk Writers Association and China Art Palace (Shanghai Art Museum). The exhibition lasts until May 8th. During the epidemic prevention and control period, there is no opening ceremony for the exhibition, and it is recommended to watch the exhibition at the wrong peak.

　　Investigation and study are the basis of seeking something and the way to accomplish it. Paying attention to investigation and research is a fine tradition of our party.

　　The General Secretary of the Supreme Leader stressed that it is necessary to vigorously carry out investigation and research in the whole party. In October 2020, General Secretary of the Supreme Leader delivered an important speech at the opening ceremony of the training course for young and middle-aged cadres in the autumn semester of the Central Party School (National School of Administration), stressing that investigation and research are the basic skills for doing a good job. We must learn to investigate and study, and improve our working skills in investigation and study. Investigation and research should be regular.

　　New era, new mission. In the face of new problems in development and new challenges on the road to reform, how to do a good job of investigation and study and find a scientific solution? We interviewed some party member, cadres and experts.

　　Inherit the tradition and play the "first move"

　　The unity of subjectivity and objectivity, theory and practice is the consistent principle of our party. Carrying out investigation and research is an important part of it. The proposal of major strategies and the introduction of major decisions are inseparable from in-depth research and scientific research.

　　Paying attention to investigation and research is an important heirloom for our party to do a good job in leadership in various historical periods of revolution, construction and reform. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has taken in-depth investigation and study as the "first move" to carry out work, introduce policies and formulate strategies. "Now, the whole party inherits the party’s fine traditions and attaches great importance to investigation and research, which has become an opportunity for us to carry out our work scientifically and constantly overcome difficulties ‘ Golden key ’ 。” Xie Chengxin, vice president of the Hunan Provincial Party History Research Institute, said.

　　To carry out investigation and study, in order to be solid and in-depth, we must exert ourselves with heart and affection. It’s hard to gain anything if you don’t jump down and sink to the front line and see and experience it yourself.

　　For Zhu Yegan, investigation and research is a basic skill. As the deputy director of the Comprehensive Research Office of the General Office of Anhui Provincial Party Committee, one of Zhu Yegan’s duties is to carry out investigation and research to provide reference for decision-making. What impressed him the most was a survey on "Anhui province implementing the national strategy of integrated development of the Yangtze River Delta".

　　"Yangtze River Delta Integration" is a national strategy. How should Anhui integrate better? The policy research department of Anhui Provincial Party Committee dispatched a special person to form a research group, and conducted separate research inside and outside the province. The first thing to do is desk work, and Zhu Yegan "caught all the relevant information" and "chewed" it all over. Secondly, the choice of research points. "The Yangtze River Delta is integrated and Shanghai is the leader, so our research points outside the province are selected in Shanghai." Zhu Yegan said that it is necessary to find Anhui’s comparative advantages through research, and then optimize the layout of the industrial chain and create an innovation platform.

　　Go to the scene and find ideas. "We talked face to face with the cadres of the Yangtze River Delta Regional Cooperation Office, the Political Research Office of the Shanghai Municipal Committee, the Lingang Group and other units, and many sparks of thinking collided; Go deep into the park, visit enterprises, and go to Shanghai caohejing Emerging Technology Development Zone and Songjiang G60 Kechuang Cloud Gallery for field research. " Zhu Yegan introduced that on the way to Songjiang New Town, a 1.5-kilometer building complex in Fiona Fang came into their eyes, with a cloud-like roof and ups and downs. "So this is Songjiang G60 Kechuang Cloud Gallery!" Going in, all kinds of new industries and innovations have opened our eyes and inspired many new development ideas … …

　　"Through investigation, we have a deeper understanding of innovation, and thus put forward suggestions for building a scientific and technological innovation circle in the Yangtze River Delta and promoting innovation synergy in a wider scope." Zhu Yegan introduced that this research proposal is also in line with the relevant contents of the Outline of the Yangtze River Delta Regional Integration Development Plan released by the central government.

　　Based on the current situation in the province and the experience of research outside the province, the research team polished more than a dozen comprehensive research reports and special reports on industrial development and innovation synergy, which provided reference for relevant decisions in the province.

　　It is a practical and effective working method to carry out investigation and research around the center and serve the overall situation. How can the central policy be implemented at the local level? Will the documents formulated by the province be "acclimatized" at the grassroots level? Can the good practices in one place be promoted on a wider scale? To answer these questions, in-depth research is the only way.

　　Yang ziyong, director of the second division of the reform office of Hunan provincial party Committee, once served as the captain of the poverty alleviation work in the village in Fenghuang county, Xiangxi. How to realize rural revitalization after poverty alleviation in rural areas? What talents do you need to support the industry? This is what Yang Ziyong and his colleagues have been thinking about for a while.

　　In order to find the answer, they went to Fenghuang County to investigate. Everyone enters the village and enters the household, asking carefully and recording carefully. The survey found that although Fenghuang County did not get rid of poverty for a long time, some characteristic industries in villages and towns developed very well. This has a lot to do with the local emphasis on using young, highly educated and thoughtful village cadres.

　　Seeing the changes in rural areas and farmers with their own eyes, Yang Ziyong and his colleagues realized the important role of talents in rural revitalization. The investigation formed a special report to provide reference for the relevant decision-making of Hunan Provincial Party Committee. "Next, we will conduct more research on rural revitalization from multiple angles and aspects to provide more help for expanding policy supply." Yang Ziyong said.

　　For leading cadres at all levels, in order to improve the scientific level of decision-making, investigation and research must run through the whole process of decision-making. "For the issues related to the overall situation of reform, development and stability in this region and this department, we should insist on not making decisions without investigation, and making decisions after investigation." Xie Chengxin pointed out that it is necessary to uphold and improve the research work system of leading organs and leading cadres, and promote the regularization and normalization of research.

　　Make friends with the masses and be a good "pupil" of the masses.

　　Carrying out investigation and research is an important way to keep close contact with the masses. Good investigation and study must come from the masses and go to the masses.

　　In 1930, during the investigation in Xunwu County, Comrade Mao Zedong directly held an investigation meeting with people from all walks of life, and mastered a large number of first-hand materials, such as the output and price of various products in the county, the number and proportion of people from all walks of life in the county, the varieties and income of various shops, the amount of land and income distributed by farmers everywhere, and the political attitudes of all kinds of people. This in-depth, pragmatic style has set a benchmark and example for the investigation of cadres in party member.

　　How can investigation and research achieve practical results? We must put down our airs and dive down, go deep into the fields and factories and mines, discuss problems with the masses, listen to their voices, observe their emotions, feel their sufferings, sum up their experience and absorb their wisdom.

　　"Make friends with the masses, and be a good one ‘ Pupils ’ In this way, we can find the real problem and touch the real situation. " Yuan Naiyu, executive deputy director of the Organization Department of Yaohai District Committee of Hefei City, Anhui Province, said, "If the grass-roots investigation is not done properly, it will easily become superficial. If you want to know what the masses think, you must integrate into the masses. "

　　Once, Yuan Naiyu and his colleagues, as volunteers, went to Dingyuan Mansion Community in Fanchang Road, Yaohai District to participate in the community cleaning. With half a bucket of water at their feet and a rag in their hands, the way they tried to clean the glass attracted the praise of the residents, and Yuan Naiyu took the opportunity to talk to everyone.

　　"Old man, how do you feel living here? Is there any inconvenience? " "What all good, is the lack of an activity place. There are many elderly people in the community, and many people like to sing and dance. The venue is easy to find when it is sunny, and it is inconvenient when it is windy and rainy! "

　　I found the needs of residents at once, and also had the topic of further investigation. Around this issue, they visited many communities and held symposiums to listen to the opinions of residents. Soon, Fanchang Road Community built a party-mass service station in Dingyuan Mansion. In addition to vocal music, dance and calligraphy, there is also a "3: 30 class" to meet the needs of young parents. Up to now, Yaohai District has established 115 "neighbors" party and mass service stations.

　　After long-term research at the grassroots level, Yuan Naiyu has worked out a set of his own research methods: defining the purpose of research, classifying and layering, combining points and areas, creating a good research environment and establishing a feedback mechanism. "After the investigation, it is necessary to exchange, compare and repeat the work, systematize the scattered knowledge and deepen the superficial understanding until we find the essential law of things and find the correct way to solve the problem. Sometimes it even takes many investigations to get closer to the truth. " Yuan Naiyu said.

　　Good research can get twice the result with half the effort. "After the investigation, if you can’t finish the report, you should put it on the shelf. It is necessary to strengthen the application of the results, let in-depth research guide scientific decision-making, and promote new progress and breakthroughs in the work." Zhu Guiping, director of the Academic and Editorial Committee of the Anhui Provincial Party History Research Institute, said.
