BYD’s fifth-generation DM technology is "digging" out for fuel consumption.

technical background

Motor advantage

strong

The instantaneous output peak torque at low speed is large. If the engine is used for high torque output, its related technologies are basically monopolized by relevant manufacturers in Europe and America.

fast

The motor torque adjustment is 20 times faster than that of the engine. At present, there is no gearbox to adjust the conversion torque in the electric drive on the market, and the electric control cycle is only 5ms, while the intake, compression, work, exhaust and power output of the engine take 100ms in one cycle.

So it’s more direct

accurate

Compared with the oil truck, the resolver identification accuracy is 300 times higher, the former is 0.02 degrees, while the latter is 7.5 degrees. Such applications as the ESP function of the chassis system are basically mastered by Bosch.

(B) the advantages of the engine

Steady-state high-efficiency kinetic energy output, that is, the steady-state high-efficiency generator engine and the series mode function in the middle and low speed state, and the steady-state high-efficiency driving in the high-speed cruise stage, while if the speed changes frequently in the middle speed driving, the excess engine energy is recovered by means of motor parallel speed increase or motor charging.

The core of the optimal architecture selection of BYD’s power system (pay attention to the non-planetary gear architecture) lies in how to give full play to the electric driving power and how to dispatch the engine power, as shown in the following figure.

(3) Comparison between PHEV and HEV

The fuel consumption is low. After all, for DM, the engine is only an aid. In most cases, it is only used to generate electricity for extended range when commuting. With high-power motor driving, the driving experience will be much better. At the same time, it has a large battery support and has the function of external discharge.

The fifth generation DM technology

Three major architectures

Power architecture based on electricity

Plug-in special high-efficiency engine: the engine with the highest mass production thermal efficiency of 46.06% in the world, and the improvement measures include

The world’s highest ultra-high compression ratio is 16. For the problems such as knocking and thermal management that may be caused by this, measures have been taken.

In order to improve the oxygen content of intake air, a high tumble port is adopted, and the combustion efficiency is improved by oxygen-enriched environment.

The EGR system is newly designed, and the middle urging is changed to the front urging.

The shape and inner wall of the combustion chamber are specially optimized.

Intelligent EFI system (mentioned again later)

The cylinder block and the cylinder head are cooled separately, and the energy consumption of the engine cooling and cooling system itself is reduced.

An intelligent variable lubrication system is designed to reduce engine friction loss.

Optimization of engine intelligent start-stop strategy

In the process of conventional engine starting, the instantaneous current will be very large when starting with a small battery of 12V, so the engine speed can only be raised in a certain period during the process of pulling the engine; Using high-voltage power electric drive to start can reduce the current and pull up the engine speed more quickly, and also avoid the resonance chattering problem that may be caused by the motor pulling up the engine;

At the same time, in the process of quickly pulling up the engine speed, the rapid power output of the engine itself is ensured by excessive fuel injection.

The energy loss can be reduced by 16%.

Extreme control optimization of system efficiency

By using the power battery as the energy reservoir, the engine can maintain a more efficient working condition as much as possible, and make full use of the driving advantage mainly based on electricity.

EHS electric hybrid system

electrical machinery

Segmented magnetic steel & ultra-thin silicon steel sheet to reduce magnetic loss and eddy current loss.

The double mechanical pumps in the motor cooling system are upgraded to the double pump coupling-rotor oil throwing technology, that is, one mechanical pump and one electronic pump, and the latter is started and stopped as needed, so the cooling process is more detailed.

clutch

The transmission efficiency between the motor and the wheel end is improved, which is transmitted by two gears and bearings. The previous generation adopted cone bearing, which has high strength but low efficiency, so it was upgraded to ball+column bearing and high efficiency clutch.

The motor speed is 16,000 rpm (132 kW, 316N.m) in the previous generation, and now it is 18,000 rpm (120 kW, 210 N.m); And the volume, power and torque of the motor are all reduced, but the power is not weakened, and the output of the wheel end is only amplified by a larger gear ratio.

The comprehensive working condition efficiency is improved by 5%

Insert-mix special blade battery

The energy density increased by 15.9%, the discharge rate increased by 33%, and the energy recovery increased by 20.3%. Because the battery capacity is large, the weight of the vehicle is bound to increase, which puts forward higher requirements for energy consumption. Therefore, part of the solution is made by improving the energy recovery rate, making a small motor mention and weight.

Charging and discharging experience upgrade

The slow charging power is upgraded from 3.3kw to 6.6kw.

DC fast charge for 21 minutes.

The external discharge is increased from 3.3kw to 6kw to meet the needs of more outdoor vehicles.

12V Ferrous lithium phosphate starter battery.

Status decline, especially in the process of vehicle starting, which was originally powered by 12V battery and transferred to electric drive.

The weight dropped from 12kg to 2.2kg

The small battery will have the same life cycle as the whole vehicle, so there is no need to change it frequently, and there is no need for the small battery to be dead.

When the small battery loses power, the power battery will charge it; If the power of the large battery is not enough, it will start the engine stomach power battery to replenish power. So don’t be surprised to see the car parked there and no one suddenly started in the future.

The small battery has its own independent BMS, which is used to communicate with the power battery.

Full temperature range vehicle

Active air intake grille, under the condition of low temperature, when the engine needs to be warmed up, the air intake grille is closed, and the water temperature rises faster; In hot weather, open the air intake grille to exchange heat and improve the heat dissipation in the front cabin; Close the air intake grille at high speed to reduce wind resistance.

Battery thermal management system

The battery direct cooling technology is adopted, and the battery is directly blown by the cooling capacity of air conditioner.

The temperature equalization technology is improved, and the shape of the cold plate flow channel is optimized to make the effective area better. The active temperature equalization technology is used, and the control valve is arranged at the cooling port, which is actively opened when the temperature needs to be lowered, so that the temperature equalization is improved by 45%, the battery activity can be kept in the optimal temperature area better and faster, and the energy consumption is saved by 34%.

The application of pulse self-heating technology, that is, heating through high-frequency charging and discharging between batteries, improves the heating speed by 60%.

Cabin thermal management, through intelligent switch internal and external circulation, actively control the compressor, blower and internal and external circulation switch according to the temperature, light and position (such as tunnel environment) inside and outside the vehicle.

Seven-in-one power domain control, through the improvement of chip and communication speed, strengthens the integration of all components, improves the power density of electric drive system, and improves 18.3%.

Wind resistance of the whole vehicle is 0.26Cd.

Low wind resistance rim

Low drag caliper

The integrated flat chassis, which has been extensively evaluated on the Internet, is no longer an oil-to-electricity structure. The layout and technology of the whole car chassis have been improved a lot, and of course the comfort has also been significantly improved.

Electronic and electrical architecture

Combined with different scenes and different parts of vehicles (such as oil, machinery, electricity, liquid, heat, etc.), the intelligent switching of vehicle modes, intelligent power distribution and intelligent voltage adjustment are carried out through historical massive data and AI technology.

The AI energy consumption mode of the vehicle system will intelligently adjust the power consumption or oil consumption strategy according to the congestion situation and road conditions during the navigation of Gaode map.

Recently, Ms. Bian from Shanghai bought 10 Jin of peanuts online for 6.81 yuan in the live broadcast room. After receiving it, she found only 10. Ms. Bian said in an interview with @ Litchi News that at the time of live broadcast, the merchant said that 10 Jin of peanuts were guaranteed not to be bad. Now the store has been cancelled, and the delivery phone can’t get through. I can’t contact the merchant myself and feel cheated.

　　The Meicheng mooncake controversy continued to ferment. On September 18, the Guangzhou Huadu District Market Supervision and Administration Bureau notified the relevant situation of Meicheng mooncakes, and introduced the business operation, trademark use and food quality inspection of the related companies of Meicheng mooncakes. The Market Supervision Bureau has sent a letter to the municipal supervision department where the live broadcast platform is located and the municipal supervision department where the live streaming company is registered, requesting assistance in the investigation. The relevant situation needs to be further verified. Next, the relevant departments will closely follow up the progress of the incident, carry out further verification of the cooperative relationship and cooperation content between Guangzhou Meicheng Food Co., Ltd. and the relevant live streaming hosting platform, and strengthen the supervision and compliance guidance of relevant enterprises.

　　As the location of the moon cake manufacturer, the notice of the Huadu market supervision department explained to the public the complex relationship between several companies involved in Meicheng moon cakes, and explained the testing of their products for inspection and the results of the regulatory department’s active sampling of moon cake manufacturers in the jurisdiction. At present, it seems that no quality and safety problems have been found in the moon cake products involving controversial topics.

　　Of course, it must also be noted that consumers and netizens have paid attention to Meicheng mooncake products from beginning to end, and only a small proportion have been placed on product quality issues. More controversial points have fallen on whether there is false propaganda in content such as "Meicheng is a big brand" and "Hong Kong Meicheng" during the sales of the product through the live streaming platform. This is also the issue of "cooperative relationship and cooperation content" that the manufacturer and the relevant live streaming hosting platform need to further verify as reported by the Huadu District Market Supervision Department.

　　Is it the manufacturer who is marketing the so-called "big brand in Hong Kong" in the way of "registered in Hong Kong and produced in the mainland", or is the live broadcast platform deliberately creating a so-called "Hong Kong-made" atmosphere based on the exaggerated expression of oral broadcast to mislead consumers? As a physical product of mooncakes, in the traditional marketing scenario, consumers can of course make judgments based on the detailed geographical labels of the manufacturer. The packaging of the product called "Hong Kong Meicheng Mooncakes", even the smallest font, clearly indicates its true place of production. But in the emerging live broadcast environment, not only can the product not be observed in detail at the first time, but the colloquial and exaggerated characteristics of the live broadcast may also be more misleading.

　　The relevant investigation is still ongoing. The way and content of the cooperation between the manufacturer and the relevant live streaming host platform need to be investigated in depth, and whoever is responsible will have to bear the responsibility. While the public is waiting for further investigation conclusions and handling results, it is also necessary to understand the series of "gameplay" of Meicheng mooncakes involved.

　　According to the report of the market supervision department, Guangzhou Meicheng Food Company has obtained the business license and the record of selling prepackaged food, and is a food trader that meets the qualification requirements. At the same time, Guangzhou Meicheng Technology Company also has the business license and food production license, and the quality management system and production process environment also meet the requirements. Including the brand related to "Hong Kong Meicheng Mooncake" used by it is from the brand authorization of Hong Kong Meicheng Food Group, and all the legal procedures seem to be in place.

　　Combined with the previous combing of the media, Guangzhou Meicheng Company registered in 2014 is the "production base" of Hong Kong Meicheng group company registered in Hong Kong in 2019. Hong Kong Meicheng group company registered a number of trademarks containing the words "Meicheng" and patterns in Hong Kong in 2023 and 2024 respectively. Among them, the trademarks of "Hong Kong Meicheng Mooncake" and patterns were registered on September 22, 2023. This set of operations can easily make consumers think that there are doubts about the so-called "Hong Kong is a shelf company". Before that, there were indeed situations where some products were registered overseas but only sold well in China.

　　According to an interview with a person in charge of the company involved by Red Star News, it is said that its brand is registered in Hong Kong, but because "the price of workers in Hong Kong is higher, the factory is located in the mainland". It should be noted that it is not uncommon for products of foreign brands to be OEM in the mainland, but there is still a huge difference between the OEM production of existing foreign brands in the mainland and the so-called quality image of mainland products through overseas registration. This is also the reason why legal experts maintain that the title of products in a specific region needs to be based on "product sales and promotion activities".

　　It is not where a trademark is registered that it naturally becomes a "big brand", not to mention that this set of extremely convenient overseas registration procedures has been repeatedly blessed in the live broadcast scene through the exaggerated expression of live streaming host and the platform of Hong Kong artists. What needs to be found out now is what role do manufacturers and related live streaming host platforms play in this fake Hong Kong capital and fake Hong Kong products marketing farce? The differences between the legal concept of trademarks and the geographical perception of the public need to be further clarified by the market supervision department through case-by-case enforcement.

　　On December 18th, the People’s Bank of China began to issue a set of commemorative coins for the 2020 New Year, which was "second light" in many places. Since the beginning of this year, the People’s Bank of China has issued commemorative coins for many times, which has been widely concerned by the market. Not long ago, the first special-shaped commemorative coin — — Taishan commemorative coins were sold out just after they were put on sale, and the face value of 5 yuan was sold online to 24 yuan.

　　Why are commemorative coins widely concerned? What is the purpose of distribution? Why does the price of commemorative coins rise and fall?

　　The first special-shaped ordinary commemorative coin was sold out.

　　On November 28th, the People’s Bank of China issued the World Cultural and Natural Heritage — — Taishan Ordinary Commemorative Coin, with denomination of 5 yuan, with rounded square shape, circumscribed circle diameter of 30mm, made of brass alloy, has issued 120 million pieces.

　　This is the first time that the People’s Bank of China has issued a special-shaped ordinary commemorative coin, which has been widely concerned by the market. As one of the official distribution channels, China Construction Bank’s official website data shows that after the reservation was started in Beijing, it took only 10 minutes to break through 2.48 million pieces. At 0: 40 on November 21st, the number of online reservations in Beijing was zero. Those who don’t have an appointment can only go to the business hall early the next morning to make an appointment. At 15: 40 on November 21, the system showed that the number of offline reservations in Beijing was zero.

　　"This Taishan commemorative coin is very special and feels more collectible." Ms. Liang, a Beijing citizen, has a lot of commemorative coins in her home, ranging from commemorative coins for the 50th anniversary of the founding of Xizang Autonomous Region to commemorative coins for the Year of the Rooster. "My first set of commemorative coins is a gift from a friend, and it is a the Year of the Loong commemorative coin, because I belong to the dragon. Since then, I have been paying attention to various commemorative coins issued by the central bank every year. When I see something I like and have special significance, I will buy one set. "

　　What is a commemorative coin?

　　Commemorative coins are legal commemorative coins issued by a country to commemorate international or domestic political, historical and cultural events, outstanding figures, places of interest, rare animals and plants, sports events and so on. Including circulating commemorative coins and non-circulating commemorative coins. In China, circulating commemorative coins are also called ordinary commemorative coins, including commemorative coins and commemorative banknotes, which are generally made of base metals such as copper, nickel and zinc; The non-circulating commemorative coins, also known as gold and silver commemorative coins, are generally made of precious metals such as gold and silver. Ordinary commemorative coins have the same function as the current RMB, and are circulated at the same value as the RMB with the same denomination.

　　Where are commemorative coins issued?

　　The Regulations of People’s Republic of China (PRC) on the Administration of Renminbi stipulates that the People’s Bank of China may issue commemorative coins as needed. If the theme of commemorative coins involves major political and historical themes, it must be approved by the State Council. 30 days before the issue, the People’s Bank of China will make an announcement to the public, announcing the theme, face value, material, pattern, style, specification, circulation and issuing time of commemorative coins.

　　How to buy?

　　Taking Taishan ordinary commemorative coins as an example, they are issued by appointment, and China Industrial and Commercial Bank, China Agricultural Bank, China Bank and China Construction Bank respectively undertake the appointment issuance of Taishan ordinary commemorative coins in some provinces, autonomous regions and municipalities directly under the Central Government. The public can make an appointment to register through the websites or business outlets of the above four banks with the original ID cards of the second generation, and the quota for each person to make an appointment and exchange is 20.

　　Issue hundreds of sets of commemorative coins in 35 years

　　Since 1984, the People’s Bank of China has been issuing commemorative coins for 35 years, and has issued hundreds of ordinary commemorative coins (commemorative banknotes). Among them, the "Commemorative Coin for the 35th Anniversary of the Founding of People’s Republic of China (PRC)" issued on October 1, 1984 is the first circulating commemorative coin officially issued by the People’s Bank of China, which laid a good foundation for the issuance of circulating commemorative coins.

　　Counting hundreds of sets of commemorative coins in the past 35 years, in addition to the "earliest issue", there are several "most" worthy of attention.

　　Issue at least — — The 30th Anniversary Commemorative Coin of Ningxia Hui Autonomous Region, issued on September 20th, 1988, is the least circulated commemorative coin by the People’s Bank of China so far, with a complete set of one commemorative coin and a circulation of only 1.56 million.

　　Minimum face value — — The "Commemorative Coin for the 6th National Games" issued on November 20th, 1987 has a face value of 10 cents, which is a set of commemorative coins with the lowest face value, the smallest specification and the lightest metal weight.

　　In addition, there is the largest diameter — — "Special commemorative coin for rare animals" in 1993, with a diameter of 32 mm；; The most public welfare — — On October 26th, 1994, the "Commemorative Coin for the 5th Anniversary of Project Hope" was issued, and the Chinese and English logo of "Project Hope" … …

　　Over the past 35 years, the People’s Bank of China has formed certain characteristics in issuing commemorative coins.

　　The circulation is increasing. In 2003, the circulation of Lunar New Year sheep was 10 million; in 2009, it was 30 million; in 2012, it was 80 million; in 2014, it was 100 million; and at the beginning of this year, it was as high as 250 million. It can be seen that the circulation of commemorative coins has increased year by year in recent years.

　　The theme of distribution is getting richer and richer. From the first set of commemorative coins issued in 1984 to commemorate the 35th anniversary of the founding of New China, to the anniversary of the founding of five autonomous regions, to sports series, great men series, rare animals series, the theme of New Year’s greetings and auspicious culture series, etc., the commemorative coins issued by the People’s Bank of China have become more and more rich in themes and covered more and more widely.

　　The distribution method is becoming more and more mature. In 2015, the People’s Bank of China began to make an appointment for redemption in some provinces and cities, and it was not until 2017 that all new year chickens were issued. At present, many banks such as Industrial and Commercial Bank of China, Agricultural Bank of China, Bank of China and China Construction Bank are responsible for the appointment of commemorative coins in some provinces, autonomous regions and municipalities directly under the Central Government. Citizens can make an appointment online at the undertaking bank official website or at offline outlets.

　　Blindly following the trend is risky.

　　The Taishan ordinary commemorative coins issued at the end of November are so popular that the "yellow cattle" will naturally not be absent. Commemorative coins with a face value of 5 yuan can be sold as high as one in 24 yuan on an e-commerce platform, with an increase of over 300%. A barrel of 20 pieces soared from 240 yuan to 600 yuan, and some people even shouted out the high price of 3,500 yuan for five barrels.

　　Why is it so hot? According to the analysis of commemorative coin lovers, on the one hand, due to its small face value and circulation, the market capital pressure is relatively small, and the collection threshold is low; On the other hand, the smaller the face value of commemorative coins, the easier it is to be fried. In addition, factors such as small circulation and few appointment opportunities have also increased the scarcity of Taishan ordinary commemorative coins, thus pushing up the price.

　　It is not advisable to speculate in money. The business management department of the People’s Bank of China specially issued an information warning, reminding the general public, especially elderly consumers, to be cautious in coin collection, to raise their awareness of self-protection and not to believe in relevant advertisements. According to industry insiders, although the market response has been enthusiastic after the issuance of commemorative coins in recent times, the main value of commemorative coins lies in collection, and the risk of blindly speculating coins is high.

　　The relevant staff of the People’s Bank of China said that the recycling link is an important prerequisite for maintaining the sound development of the commemorative coin market. For collectors, commemorative coins will lose some value if they cannot be converted into working capital. However, there is no formal recycling channel for commemorative coins at present.

　　Although Ms. Liang has collected some commemorative coins at home, she has never participated in speculation. "I think speculation is like stock trading, and the risk is too high. I bought commemorative coins purely because I like them, and the total price of a set is not high. I am happy at home. " Many insiders also said that commemorative coins can be collected as personal interests, but speculation is absolutely impossible.

The Secret Service Task starring Han Geng, Daxun Wei and Li Yitong is being broadcast.

Among them, Daxun Wei, as a supporting role, is known as the first explosion in summer this year, and is a famous table-lifting coffee. With less than 90 minutes’ appearance in a drama with more than 40 episodes, it won the first fault flow and became a miracle this summer.

After becoming popular, a network variety show "Let’s Go Now" as a flight guest has also become the program with the highest click-through rate in the history of its broadcast platform. Participated in the variety show "Hello, Saturday" also won the highest ratings of this program since its broadcast.

Therefore, everyone will naturally pay such high attention to this new work of his and want to see how it performs. However, it’s a pity that he doesn’t have many parts in this play. However, the fans are not very angry, which is not surprising, nor does it conflict, because Daxun Wei’s fire is not the same as others, because it depends on the temperament given to the characters by itself and the carnival of passers-by.

Not to eat the role bonus, but to give life to each other

The whole drama "You are my fireworks" is extremely unfriendly to the role of Meng Yanchen. Because in the novel, he is not the official match of the heroine, and his personality has problems and shortcomings. In addition, because he is the main actor, the scenes in the play have been deleted in pieces, and many high-light scenes have all been cut, and several pseudo-orthopedic scenes expected by countless fans have all been deleted.

To be honest, it is impossible for an actor to get a bonus from such a character who wants to find meat through his teeth. However, this role and the actor himself are all on fire again, which makes everyone fascinated by this role.

Because this character seems to have a life, it is not difficult for everyone to understand that it is not the screenwriter, the novelist or the director who gives Meng Yanchen life, but the actor himself, Daxun Wei who wrote a biography of the character. The character’s fire was watered by Daxun Wei’s painstaking efforts. Moreover, after the fire, Daxun Wei also carefully dared not spend too much on Meng Yan.

In the variety show, Adam asked him why he didn’t make more use of this already popular role to promote himself. He said he didn’t want to spend the banquet. His name is "Banquet Minister". Listening to his gentle voice shout out these two words, many people’s hearts have melted, and it feels that he regards Meng Banquet Minister as a real person.

Not fans brushing data, but passers-by reveling next to them

When Daxun Wei gained a little popularity with the role at first, fans were panicked, because they could not empty bottles, brush data, make pictures or play hyperbole. As for Lian Chao dialect, their hosts were all Daxun Wei himself, and the square was full of living people. There were no two identical Weibo, but all the living people were partying.

Seriously think about it, the data set of rice circles, in addition to improving some commercial value of Zhengzhu, is actually an internal carnival of fans. Capital does depend on the purchasing power of fans, but passers-by don’t buy it at all, and those who win the hearts of the people can achieve great things. This time, the fire in Daxun Wei is also a counterattack by passers-by against the behavior of pink circles that they can’t stand for a long time. No one cares about the life and death of Daxun Wei fans. The main thing is that passers-by support you and make you angry.

Daxun Wei’s fans, during the hottest period, were all quiet, for fear that after the passers-by ebbed, others would attack them, leaving them unable to fight back.

Not thinking about traffic, but hoping to achieve long-term results.

Daxun Wei knows that his looks are really inferior to other handsome guys at first sight, and he has never wanted to develop in idol dramas since he debuted, and he is not bent on being a traffic.

Now, he doesn’t want to consume popular characters to promote his new drama and jump out of the role. He also hopes that it will last for a long time in the future and achieve the long-term effect achieved by other works.

When the fire started, many media came to Daxun Wei to ask him and the role, hoping to get more enthusiasm from him and the role. In his response, Daxun Wei repeatedly said that the role is the role, he is him, and he doesn’t want to use this role for excessive consumption.

Everyone will say anything about the scene, and the real test is to see his state when the new drama is broadcast. Sure enough, he cut with the previous character. Otherwise, the film will use whatever propaganda means it can, that is, hard break, to put everything it can use on it.

　　Although he is already an "old acquaintance" of the White House, as the new president of the United States, Biden’s daily schedule is still concerned.

　　According to a report by CNN)2 on February 15, Biden, as an "old man" who has been in Washington for decades, seems to be more "handy" than his predecessor, even though he is surrounded by a large number of Secret Service agents every day, keeping up with the top secrets of the United States at any time and responding to the tracking of the news media.

　　It is reported that President Biden, who has just been in office for less than a month, has made a fixed schedule for his work: he will first have coffee with First Lady Jill every working day morning, and will start holding meetings and making phone calls in the Oval Office at around 9: 00, and he will "go home" at around 19: 00 every day, that is, return to the President’s residence on the second floor of the White House. CNN revealed that Biden often comes home from work with a stack of papers, and he always carries a brown leather briefcase when he arrives at the office.

　　According to CNN, former President Barack Obama used to read the president’s daily briefing in the evening, while Trump liked to watch TV in the evening. In contrast, Biden was an early-to-bed person, but he kept the tradition of reading letters from the American people, and there were always several letters in the files when he came home every day.

　　In fact, Biden and his wife are very familiar with the White House. He once worked here for eight years as vice president, so Biden once joked at the inauguration ceremony that "I feel like going home." According to a report in People magazine on February 3, the "First Lady" Jill said in an interview at the White House that although the White House has changed a lot, there are still some things exactly like what they remember, such as the kitchen garden left by Michelle Obama. According to CNN, after taking office, Biden showed Vice President Harris a window where he wrote a message of Valentine’s Day greetings to his wife during his tenure as Vice President.

　　According to CNN2’s report on February 16th, Biden’s work schedule is more orderly than that of Trump when he took office. Trump’s assistants used to spare a lot of "administrative time" to meet their needs of watching TV and making phone calls. Biden’s meeting seems to be held more regularly, but it usually takes longer than planned.

　　In addition to working days, Biden still insists on attending public meetings on weekends, such as church activities and so on, and usually with Jill, the "first lady". CNN commented in a report on the 16th that Biden and Jill seem to be more willing to show their intimate relationship publicly than the previous "first couple".
