BYD started the year with the king bombing, and Qin PLUS and destroyer 05 glory edition started at 79,800.

　　 At the beginning of the year, the glory version of BYD Qin PLUS and the glory version of destroyer 05 were sold from 79,800. At the same time, the price entered the era of "7", and it also had a higher configuration than the fuel vehicle of the same class, which truly achieved "both want and want". This is tantamount to dropping a bombshell on the automobile market in China, and it also shows that in 2024, BYD will no longer "show mercy" on fuel vehicles, and in order to speed up the conversion from oil to electricity, it will launch a "general attack" on joint-venture fuel vehicles at the beginning of the year.

　　Why BYD?

　　 In the impression of many people, new energy vehicles are more expensive than fuel vehicles of the same level, and at most they are oil level rights. But this time, BYD’s two glory models have achieved "electricity is lower than oil" and the price reduction is not reduced. Why can BYD do it?

　　 The first is the core cost advantage.

　　 In 2023, BYD sold a total of 3,024,400 vehicles, up 61.9% year-on-year, which is not only the annual sales champion of China automobile market, but also the global sales champion of new energy vehicles. The annual sales volume of more than 3 million not only set a record for China automobile, but also made BYD the first China automobile enterprise to enter the top ten in the world.

　　 Matching the sales growth, BYD’s huge R&D investment has exceeded 100 billion, with over 90,000 R&D engineers and 11 technical research institutes. At present, BYD has accumulated a huge and systematic "technical fish pond" and applied for over 6,700 patents in 2023 alone.

　　 On the surface, it is the price war of products, but in fact it is the system war of industries. The scale effect and the advantages of the whole industry chain give BYD the initiative in product pricing. Ultra-large-scale sales, combined with its own cost control ability and strong technical strength, make BYD have the ability and strength to show sincerity in the price of new cars, give more benefits to consumers, and let consumers really feel the dividend of BYD’s development.

　　Promote the popularization of new energy vehicles

　　 As a leader of new energy vehicles, BYD has been practicing its brand concept with practical actions.

　　 The launch of 79,800 glory models this time is a direct embodiment of this concept. As the first car company to achieve lower electricity than oil, plug-in hybrid is lower than the price of fuel vehicles. This has also become a watershed and milestone in the development of automobile categories, further improving the penetration rate of new energy vehicles and consolidating and strengthening the leading position of China brand in the A-class sedan market. The lower use cost, plus the exemption from licensing and reduction of purchase tax, makes fuel vehicles no longer have a price advantage in front of them. BYD’s intention is obvious, so that more and more consumers can afford new energy vehicles and are willing to buy new energy vehicles, thus promoting the popularization of new energy vehicles in the China automobile market.

　　 In the new energy vehicle market, BYD’s influence and appeal are beyond doubt. The launch of the Glory version of the vehicle further demonstrates its strong technical strength and cost control ability. In addition to allowing consumers to buy better new energy vehicles at more realistic prices, it will also promote the innovation and progress of new energy vehicle technology in China and promote the product upgrading of the whole industry.

Electric car battery, electric car battery is dry battery or lithium battery？

1. Is the battery of electric vehicle a dry battery or a lithium battery?

Dry batteries are generally lead-acid batteries. With the same capacity and voltage, the weight of lead-acid battery is three times that of lithium battery. Lead-acid batteries also have a short life. Current lead-acid batteries can’t go far in two years, while lithium batteries can last for five years. Due to its own weight, the battery life is incomparable to that of lithium batteries. But dry batteries are cheaper. It depends on how you choose. What suits you is a good lithium battery electric car: advantages: high efficiency. The car body is light, the mileage is long, and the requirements for the use and maintenance of users are not strict. Disadvantages: the price is high, and the domestic lithium battery technology is uneven, and the lithium battery used for electric vehicles has potential safety hazards. Lead-acid battery electric vehicle: advantages: high cost performance. The battery is relatively cheap, with large capacity, many battery brands and mature technology. Disadvantages: the efficiency is not very high. The battery pack is bulky, resulting in a heavy body and short mileage, so it is necessary to maintain the battery regularly.

2. Is dry battery or lead-acid battery better for electric vehicles?

Electric bicycles and motorcycles have become important means of transportation in large, medium and small cities and are generally accepted by people. Compared with traditional bicycles, the price of electric bicycles is generally higher, so the service life has become the most concerned issue. In fact, the battery is one of the core components of the electric bicycle, and the service life of the battery largely determines the service life of the electric bicycle. In this regard, Chaowei Battery said that strengthening the maintenance of the battery will extend the service life of the battery. It is understood that the batteries used in electric vehicles are lead-acid batteries! Dry batteries are a scam! In addition, I will send you a message: the starting current of electric vehicles is very large, especially for electric motorcycles with high-power motors. Heavy current will damage the battery plate. The best way is to start the power supply after riding the electric car like riding a bicycle. After the battery is used for a period of time, some active substances will inevitably settle. If the active substance is not activated in time, it will definitely affect the capacity of the battery. Deep discharge the battery once. Judging from the current use of electric vehicle batteries, lead-acid batteries are mature in technology, cheap in price and stable in performance. The dry battery of electric vehicle is mainly lithium battery, which is twice as expensive as lead-acid battery, but its service life is longer than that of lead-acid battery, but with the increase of charging times, its service life will become shorter and shorter. For example, lead-acid batteries need to be replaced once a year, and lithium batteries can be replaced once every two years, but lead-acid batteries can be replaced once a year, and the cruising range of lithium batteries will be shortened in the second year, which will affect their use.Compare their respective prices, calculate the cost and your own usage, and see which is more cost-effective. I recommend lead-acid batteries. Dry batteries are easy to use, durable and small in size, but the price is a bit expensive. It is the future development. Lead-acid batteries will be out of stock. Use lead-acid batteries. The storage capacity is stronger. If you ride it every day, you’d better charge it every day. I know a lot of fake batteries, so it’s unnecessary, right?

3. Is lithium battery for electric vehicle really better than lead-acid battery?

Lead-acid batteries have the largest number. Lead-acid batteries are the cheapest and most commonly used. China is the largest producer of lead-acid batteries in the world. It contains less pollution components and has good recyclability. The disadvantage is that the specific volume is small. In other words, under the same capacity, the weight and volume of the battery are very large. At present, lead-acid batteries are basically developed from floating batteries. Floating battery is not suitable for fast charge and high current discharge. Although technicians have spent a lot of energy on effective improvement and can put it into practical use, its service life is still very long. Colloidal batteries belong to a development category of lead-acid batteries. The simplest method is to add gelling agent to sulfuric acid, so that sulfuric acid can be electrically liquefied into colloidal state. The battery with electro-hydraulic colloid state is usually called colloid battery. In a broad sense, the difference between colloidal battery and traditional lead-acid battery is not only that electro-hydraulic battery is changed into colloid. For example, non-condensed hydrocolloids belong to colloidal batteries in electrochemical classification structure and characteristics. Another example is that polymer materials are attached to the grid, commonly known as ceramic grid, which can also be regarded as the application characteristics of colloidal batteries. Recently, some laboratories have added targeted coupling agents to the polar plate formula, which greatly improved the reaction utilization rate of the polar plate active materials. According to unpublished data, its weight ratio can reach 70wh/kg. These are the current industrial practice and the application examples of colloidal batteries that will be industrialized soon. The difference between colloidal batteries and conventional lead-acid batteries is that from the initial understanding of electrolyte gelation to the study of electrochemical characteristics of electrolyte basic structure,Then to the application and promotion of grid and active materials. Its most important feature is to manufacture better batteries along the road of lead-acid battery industry for 150 years with relatively small industrial cost. Its discharge curve is flat and its inflection point is high, and its specific energy is 20 times larger than that of conventional lead-acid batteries. The battery of electric vehicle must choose lithium battery. Lead-acid batteries used in traditional electric vehicle batteries will produce a lot of pollution and lead vapor after being discarded. According to statistics, a batch of waste batteries of electric vehicles will pollute tens of thousands of tons of water. Lead is not easy to be excreted, and it can also cause diseases such as metabolism, reproduction and nerves. Once the lead content in the human body exceeds the standard, it will lead to mental decline, fetal malformation, and it is easy to induce malignant tumors in children and even lead to death. Compared with lead-acid batteries, lithium batteries have natural advantages in environmental protection. The materials used for lithium batteries do not contain harmful heavy metals such as cadmium, lead and mercury. In the process of production and use, lithium batteries do not produce any pollutants, which ensures human health. Solved the problems of water source and soil. In addition, lithium batteries also have the advantages of large specific energy, long cycle life, low self-discharge rate and no memory effect. The storage energy density of lithium batteries is high, which has reached 460-600wh/kg at present, which is about 6-7 times that of lead-acid batteries. The service life can reach more than 6 years, and the anode lithium iron phosphate battery can charge and discharge 1cdo. Can be used for 10,000 times; It has high power tolerance, and the Ferrous lithium phosphate lithium-ion battery used in electric vehicles can realize the charge and discharge capacity of 15-30c, which is convenient for high-intensity start acceleration;The self-discharge rate is extremely low, which is generally lower than 1% per month at present, less than 1/20 of that of Ni-MH battery; Lithium battery can completely meet the power requirements of electric vehicle batteries, and become an ideal product for electric vehicle applications because of its green and environmental protection characteristics. I hope it will help you.

4. Why are the batteries of electric vehicles all lead-acid batteries?

Of course not, because lead-acid batteries have the following characteristics and advantages: sealed structure, no acid leakage and no acid mist emission. One-way exhaust valve (also called safety valve), the function of this valve is that when the amount of gas inside the battery exceeds a certain value (usually expressed by air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve automatically opens, discharges gas, and then automatically closes the valve to prevent air from entering the battery. Compared with ordinary lead-acid batteries used in automobiles, valve-regulated lead-acid batteries have two main characteristics: one is sealing; The second is dry. Sealing means that there is basically no acid mist discharged. Generally, the VRLA battery is "zero emission" during its operation (charging and discharging), and only when the gas pressure in the battery exceeds the opening pressure of the safety valve in the later period of charging can a small amount of mixed gas of hydrogen and oxygen be discharged, and at this time, a small amount of acid mist is filtered out by a filter material. Dry state means that the VRLA battery has no free flowing electrolyte, and can be placed in any direction, not afraid of bumps and collisions, and no acid will leak out even if the shell is broken. During the use of lead-acid batteries, chemical energy is only continuously converted into electrical energy, and electrical energy is also converted into chemical energy, which is repeatedly circulated, thus causing "zero emission" to the external environment and no pollution to the environment, which you do not have with 40 No.5 batteries. 1. Electric vehicle batteries are not all lead-acid. Now there are many lithium-ion electric vehicle batteries, and most of them are composed of many small batteries. The adoption of lead-acid batteries is the result of many considerations such as production difficulty, cost and reliability.2. The basic feature of lead-acid battery is that it does not need to be maintained by adding acid and water during use. The battery has a sealed structure, which will not leak acid or discharge acid mist. The battery cover is equipped with a one-way exhaust valve (also called a safety valve), which is used to prevent air from entering the battery when the gas volume inside the battery exceeds a certain value (usually expressed by air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve will automatically open, exhaust gas and then automatically close the valve to prevent air from entering the battery. 3. Compared with ordinary lead-acid batteries used in automobiles, VRLA batteries have two main characteristics: one is sealing; The second is dry. 4. Sealing means basically no acid mist is discharged. Generally, the VRLA battery is "zero emission" during its operation (charging and discharging), and only when the gas pressure in the battery exceeds the opening pressure of the safety valve in the later period of charging can a small amount of mixed gas of hydrogen and oxygen be discharged, and at this time, a small amount of acid mist is filtered out by a filter material. 5. Dry state means that the VRLA battery has no free flowing electrolyte, and can be placed in any direction, without fear of bumps and collisions, and even if the shell is broken, there will be no acid leakage. 6. During the use of lead-acid batteries, chemical energy is only continuously converted into electrical energy, and electrical energy is also converted into chemical energy, which is "zero emission" to the external environment and will not cause pollution to the environment. One reason: cheap. If you change to a lithium battery, the battery will cost thousands ~ now it mainly depends on lead acid to store electricity and generate electricity, and there is no better material to replace it. Besides, this cost is low, which is suitable for the needs first! Not all batteries of electric vehicles are lead-acid.Now there are many lithium-ion electric vehicle batteries. Lithium-ion electric vehicle batteries. Most of them are also composed of many small batteries. The adoption of lead-acid batteries is the result of many considerations such as production difficulty, cost and reliability. Your scheme is feasible in theory, but just accumulating one item based on the quality difference between batteries makes your scheme useless. Not to mention cost and reliability.

5. What kinds of batteries are available for pure electric vehicles? There are two types of batteries for electric vehicles, storage batteries and fuel cells. Batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, sodium-sulfur batteries, secondary lithium batteries and air batteries. Among them, lead-acid batteries, nickel-cadmium batteries and nickel-hydrogen batteries appeared earlier, and they are also the types of batteries that have been generally eliminated. Nowadays, the mainstream pure electric vehicles are basically lithium batteries, mainly including lithium cobalt oxide batteries, such as products; Lithium manganate batteries, such as (||) and Leaf Wind; Lithium iron phosphate batteries, such as products, (||), etc. Lead-acid battery is the most commonly used new energy vehicle battery. The polar plate of lead-acid battery is a grid made of lead alloy, the electrolyte is dilute sulfuric acid, and both polar plates are covered with lead sulfate. However, after charging, the lead sulfate on the electrode plate at the positive electrode is converted into lead dioxide, and the lead sulfate at the negative electrode is converted into metallic lead. When discharging, the chemical reaction in the opposite direction occurs. The advantage of lead-acid battery is that the electromotive force is stable when discharging, but the disadvantage is that the specific energy is small and it is corrosive to the environment. 1.

However, after charging, lead sulfate on the electrode plate at the positive electrode is converted into lead dioxide. 4. Lead sulfate at the negative electrode is converted into metallic lead. When discharging, the chemical reaction in the opposite direction occurs. The advantage of lead-acid battery is that the electromotive force is stable when discharging, but the disadvantage is that the specific energy is small and it is corrosive to the environment. For the time being, there are only experimental products for sodium-sulfur batteries for vehicles. 1. There are many kinds of fuel cells, such as hydrogen fuel cells, high-temperature fuel cells, direct methanol fuel cells, methanol reforming hydrogen fuel cells, metal fuel cells and so on. 2. At present, hydrogen fuel cells are the mainstream in the field of passenger cars, and Toyota is the representative factory. The biggest feature is that it can achieve pollution-free throughout the life cycle (from the beginning of raw material manufacturing to the final recycling). 3. The fuel hydrogen used has the characteristics of high energy density and zero pollution. The disadvantage is that the current cost is very high, and the volume power density is limited. Take the representative of the fuel cell vehicle (||) as an example, the volume of the fuel cell system of NO is roughly equivalent to a V6 engine, but the output power is only in the early 100KW, which is about 140 horsepower. The price of the whole vehicle is roughly equivalent to 338 horsepower. In fact, these two kinds of batteries can be said to have their own advantages. At present, lithium iron phosphate batteries are used a little more, because Ferrous lithium phosphate has good cycle stability.The cost is also relatively low. However, the consistency of Ferrous lithium phosphate is not as good as that of ternary battery, and there are still many problems in material stability, safety and processing technology. The specific landlord can check again, and the relevant information is still quite a lot. Personally, I recommend ternary batteries. At present, Ferrous lithium phosphate and ternary batteries are the main ones, and lithium manganate can be ignored. Take our car as an example. ev160 uses lithium iron phosphate battery, which is ternary lithium battery. Ferrous lithium phosphate’s technology is more perfect, but its future development is not as good as ternary lithium. I bought ev160, so I recommend Ferrous lithium phosphate, and I will buy ternary lithium car when ternary lithium technology is mature. Land Ark brought its newly listed pure electric vehicle v5s at the 2015 Energy Saving and New Energy Auto Show. The car was launched on October 15th, 2015, and it is the upgraded version of the first pure electric v5 launched by Land Ark in 2013. According to the staff, the car has a battery life of 150 kilometers and the price is about 75,000 yuan. Compared with lithium iron phosphate battery, ternary lithium battery has several improvements: power increase, energy density increase, charging rate increase, good low-temperature performance, and battery cells are combined and packaged. But lithium ternary is more unstable than Ferrous lithium phosphate, so the good and bad are 50% and 50% respectively.

＂Little Joy＂ word-of-mouth fermentation actor contributed a lot.

　　"Little Joy", which is being broadcasted by Oriental TV, has triggered the "pain point" topic of every family around educational anxiety, parent-child relationship, and pressure to enter a higher school, and quickly attracted a lot of attention. The continuous word-of-mouth fermentation of the play is inseparable from the whole online acting, especially the four middle school students with heavy scenes — — Lin Leier, Fang Yifan, Ji Yangyang and Eiko. The actors of the four people were affectionately called "four sons of spring breeze" by netizens. Director Wang Jun said frankly that the little actors played very well and were very aura. Recently, Beijing Youth Daily reporters interviewed Liu Jiayi and Zhou Qi, the actors of Lin Leier and Fang Yifan, respectively, to understand the story in and out of Little Joy.

　　Liu Jiayi

　　"group pet" acting beyond age

　　From being drunk and imitating Tong Wenjie’s "lesson" Fang Yifan to hearing his mother’s WeChat voice burst into tears, the newcomer actor Liu Jiaxuan showed Lin Leier’s inner world vividly, making the audience feel distressed about this child.

　　In fact, Liu Jiayi, born in 2001, has been recognized as a "small drama bone" by mainstream TV circles. In 2015, he made his official debut as the role of Sima Lun in The Roar of Tigers and the Song of Dragons, and then he also participated in hit dramas such as Gu Jian Qi Tan 2 and Action to Break the Ice. Among the Four Sons of Spring Breeze in Little Joy, "Lin Leier" is the most difficult to grasp but the most brilliant, which proves Liu Jiayi’s acting experience beyond his age.

　　Lin Leier was a nerd at first, and as the plot unfolded, the emotional world was extremely full and rich. For this change, Liu Jiayi designed some "unnatural" actions. For example, in the scene when I first arrived in Beijing, as soon as I got out of the airport, Lei Er was stuffing her clothes, sweating her palms and pinching her skirts. For example, my aunt asked Fang Yifan to make up lessons, and the angry tone scared Lei Er who was eating. Liu Jiayi said, "I will enhance the three-dimensional sense of the characters through these small details."

　　Liu Jiayi was deeply impressed by the scene of shooting a long talk with Christina. "Because the scene involves the mother’s voice in the mobile phone, this voice was actually recorded by Christina himself. The voice recorded by Teacher Christina is very lively. For example, wearing long pants and buying magazines are all very substitutive. Hearing this voice makes me instantly enter the show. "

　　In addition, the profound friendship of the "four sons of spring breeze" in the play is very enviable, and Liu Jiaxuan broke the news that he is a "group pet" among the four people. "No matter in or out of the play, we have a very good time." Speaking of the similarities with the role, Liu Jiayi said, "Lei Er and I are both high school students, but I am not a schoolmaster."

　　Zhou qi

　　Have a musical dream.

　　In the new plot, Fang Yifan once again confessed his desire to learn art to his parents at the speech meeting, and sang a song "Little Boy" which touched his parents Fiona Fang and Tong Wenjie. In fact, becoming attached to Fang Yifan is almost destiny takes a hand for the actor Zhou Qi — — Not only looks very much like Christina’s own, but also comes from studying vocal music and dancing. Now I’m taking part in "Sound Into People’s Heart 2". "Like Fang Yifan, I have a musical dream".

　　Fang Yifan in the play is a typical "Xiong Haizi", and Zhou Qi in life is basically a Xiong Haizi. "Sometimes I am quiet, sometimes I am a monkey. Compared with Lei Er, he is more monkey outside the play. "

　　Zhou Qi particularly resonated with the plot of taking the art test. However, unlike Fang Yifan, Zhou Qi’s parents supported his dream. Acting and musicals are both representatives of the art in Zhou Qi’s heart, and both performance and music are his favorite things.

　　According to Zhou Qi, the role of Fang Yifan was received through a round of interviews. Although acting is not professional for Zhou Qi, he was lucky enough to get unreserved mentoring from his parents’ actors in the play. For example, Huang Lei told Zhou Qi to act with his ears, "that is to say, to listen more. Don’t say your lines in a hurry. After listening to others, actively feel and actively respond to them. Don’t rush to say lines or make expressions. "

　　Zhou Qi is very honored that netizens ridiculed him as the "beaten" in "Little Joy". "This has become a normal state in everyone’s impression, so I accept the fact that he was beaten. But if he doesn’t get beaten one day, it may mean that Fang Yifan has really grown up and really grown up. "

Hit the water in the middle stream： artistic representation and innovation of party history

　　To celebrate the 100th anniversary of the founding of the Communist Party of China (CPC), a major revolutionary historical TV series "Hit the Water in the Middle Stream" highlights the great initiative, struggle and dedication of communist party people, and focuses on the purity of communist party people’s initial heart, the truth of doctrine, the firmness of faith and the beauty of personality. The play was produced by the Central Radio and Television General Station, produced by the TV Drama Documentary Center of the General Station and produced by China TV Drama Production Center Co., Ltd. After it was broadcast in the prime time of CCTV’s comprehensive channel at the main station, it triggered a hot discussion in the society and the communication effect was obvious. According to the data of CSM national network, the highest viewing share of "Mid-stream Hit Water" is 3.32%. On the platform of Iqiyi, "Mid-stream Hit Water" ranked third in the hot list of historical dramas. The audience and netizens have a good reputation and are known as "the pathfinding journey of revolutionary pioneers and a vivid teaching material for learning the history of the party." Analysis of its reasons, in addition to the grand structure, well-made, rich characters, there are many internal inevitable factors.

　　First, aim high and focus on the initial heart.

　　No great cause can be short of ideals and beliefs that run through it. The Communist Party of China (CPC) led the people from poverty and weakness to prosperity and strength, fulfilling the dream of several generations of China people since 1840 — — National independence, national prosperity and people’s happiness. The core of communist party’s success is, as always, to practice the concept of "seeking happiness for the people of China and rejuvenation for the Chinese nation". Focusing on this concept, Midstream Hit the Water uses a variety of innovative artistic expressions to show the Communist Party of China (CPC)’s century-long glorious course from birth, development to continuous growth, leading the people of China to forge ahead courageously.

　　Looking at "Hit the Water in the Middle Stream", people can see that the Communist Party of China (CPC) people not only inherited and developed Marxism, but also constantly strengthened and sublimated their "initial heart". "Do not forget your initiative mind" is an important proposition put forward by the Communist Party of China (CPC) in the new era, but this proposition is by no means abstract. It is rooted in every party member’s life choices and actions. From this theme work, we can see that it is also rooted in the daily work and life of TV and literary and art workers. Only by abandoning snobbery can we aim high; Only the initial resonance can resonate. Because of its accurate position and high vision, it is vivid and tough, and full of strong appeal. It not only provides rich spiritual and cultural food for the people, but also consolidates the dominant position of socialist culture in silence.

　　Second, artistic creation, the courage to innovate

　　Successful TV dramas with revolutionary historical themes must be derived from and loyal to history, but they must transcend history and sublimate their spirit, and make moderate artistic creation on the basis of reality, which just reflects the artistic accomplishment and political height of the creative team.

　　Red revolutionaries can be seen in every episode of "Hit the Water in the Middle Stream". In many chapters describing revolutionary figures, there are many plots that increase the emotional color of the creative team. On the basis of respecting history, many unknown storylines are excavated and the psychological descriptions of the creators are superimposed. For example, when Mao Zedong saw the Chinese version of the communist party Declaration for the first time, he was so excited that he couldn’t sleep at night. When he saw the wonderful place, he couldn’t help stamping his feet and praising it, which affected the sleep of the downstairs tenants several times. This interpretation depicts the pure passion of devout revolutionaries and the ecstasy when they see the way forward, which has strong political vitality and artistic appeal.

　　Hit the water in the middle stream presents the historical essence to the audience artistically, and realizes the dialectical unity of "historical truth" and "artistic fiction" Under the narrative principle of "big things are not empty, small things are not limited", the innovative media products systematically sort out the timeline of historical events, and the plot is full of chronological texture. For example, many historical events such as the diplomatic failure of the Paris Peace Conference, the May 4th Movement and the Zhang-Zhang Movement were successively restored, among which a series of events such as progressive students studying in France, the establishment of the Enlightenment Society by Zhou Enlai, Li Dazhao’s dispute with Hu Shi, and Yang Changji’s death were interspersed. Many audiences were moved by the vivid portrayal in the play, and sincerely commented that "this play can be said to have summed up that period of history in an all-round way", "the stories of revolutionary ancestors are worth understanding, and the TV series truly reflects the original appearance of history" and "there are many events without chaos, as if they were brought into the historical situation". Such historical re-creation, from the creator himself, is a sublimation and improvement again and again; For the audience, it can more easily arouse emotional resonance, thus enhancing the communication effectiveness of the main melody melody literary works and creating a spiritual atmosphere of strong confidence, warmth and gathering people’s hearts.

　　Third, see the big from the small, and moisten things silently

　　How to tell a good story about major revolutionary history is a realistic proposition faced by the propaganda ideological and cultural front, and it is also an innovative topic that the majority of creators must keep up with the changes of the times. In a revolutionary historical drama, it is not easy to keep pace with thoughts and stories, and the details and connotations complement each other.

　　Hit the water in the middle stream blends sublimity with daily life, mission with human nature, and moistens the ideal of the red revolution and the indomitable and down-to-earth spirit of struggle with silent artistic means. Starting from a small place and setting off the lofty revolutionary ideal with simple and touching details, the play can not only deeply impress the ordinary audience, but also make people sincerely pay high respect to the leaders. The main characters in the film are not only ambitious and self-sacrificing talents for saving the country, but also good sons and daughters of China with flesh and blood, affection and righteousness. For example, Yang Changji, as a modern ethicist and educator who accepted the dual influence of Confucian traditional culture and western culture, can be said to be a very discerning Bole. He once predicted: "Mao Ersheng and Cai Ersheng will inevitably be the pillars of China in the future." His thoughts and personality had a profound influence on Mao Zedong. Yang Changji died, and Mao Zedong, as a revolutionary who was concerned about the country and people, made a wreath of snow to pay homage to his father-in-law. This seemingly ordinary scene has made countless people cry. It is these well-intentioned artistic designs that vividly depict the touching images of the party’s leaders and predecessors "seeking happiness for the people of China and rejuvenation for the Chinese nation", and prove from the depths of human nature that the Communist Party of China (CPC) has strong vitality and continues to be supported by the people.

　　"Hit the water in the middle stream" is a representative of the outstanding works of the main theme that stimulates positive energy and promotes truth, goodness and beauty, and has realistic value and historical influence that cannot be underestimated. The times change and the spirit is eternal. It is more and more excellent works like this that convey the accumulation and nutrition of the Red Revolution to the broad audience silently, which not only plays an important role in ideological education, but also provides a vivid creative model for propaganda and ideological front.
