Explore the store BYD Han, the terminal has no discount, and the first two luxury versions are introduced.

After the implementation of the latest foreign brand restriction policy in Shanghai, many former foreign brand owners have set their sights on the new energy vehicle market. Among many automobile brands, BYD has always been the first choice for many consumers, especially the newly launched Han, which can be seen everywhere in Shanghai, even in the suburbs. Therefore, taking this opportunity to come to BYD 4S store, let’s take a look at why this popular car can sell so well, and finally bring you its purchase recommendation.

When I arrived at BYD 4S store in the morning, I could see a row of test cars parked there quietly next to the door, including two in BYD Han, namely Han EV (parameter picture) and Han DM. The current sales volume of this car can be seen. Oh, by the way, through this picture, the difference between the two versions, the red one without grille is EV, and the gray one with air intake grille next to it is DM, which is very simple to distinguish.

Compared with the whole BYD family, Han’s style can also be described as unique. After the slender headlights are connected with the chrome-plated decoration in the middle, they look elegant and sporty with the pressed front. However, I don’t think the gray version of the exhibition hall looks as good as red.

If you don’t talk about the body parameters, I think you can guess the level of this car by the slender size of the side. Yes, Han’s positioning is a medium and large car. Its car length has reached 4980mm, and its wheelbase has reached 2920 mm. In addition, the use of hidden door handles also conforms to the image that a pure electric vehicle should have. The ubiquitous chrome-plated material makes the car side exquisite as well.

In addition, it should be noted that the C-pillar of the ultra-long battery life version (two-wheel drive) of Han EV is different from that of the four-wheel drive high-performance version. The former is decorated with bright black, while the latter is decorated with metal, so this EV in the exhibition hall is a four-wheel drive high-performance version.

The shape of the rear also continues the simple design style of the front, and the use of penetrating taillights just fits the front face. In addition, BYD’s most signature dragon claw taillights are also reserved, but in contrast, the whole tail is more calm than the front face.

Entering the car, the interior of Han EV still continues BYD’s consistent impression of science and technology. At the same time, as a medium and large car, thanks to the use of large leather and wood grain decoration, the luxury is equally strong, which also gives this Han EV a more mature and stable impression than other models in the family.

Of course, the softer padding and the excellent shoulder support of the front seat make the seat of Han EV conform to the performance of a medium and large car.

After excluding the seats, there is no doubt about the performance of the rear space brought by the positioning of medium and large cars. In addition, an LCD control panel is provided for the rear passengers behind the central armrest, and the whole system supports the configuration of independent air conditioning in the rear, which can be said to be a combination of technology and practicality. It should be noted that Han EV also comes standard with co-pilot boss key.

As for the trunk space, the trunk space is basically the same as that of an ordinary fuel vehicle because the power batteries of the vehicle are placed below.

On the power level, the total motor power of Han EV is 163kW and 363kW respectively, the total motor torque is 330N·m and 680N·m, the battery energy is 76.9kWh, and the cruising range is 605km and 550km respectively. Among them, the acceleration time of the latter is only 3.9s seconds. As for Han DM, it is equipped with a 2.0T engine with a maximum power of 141kW and a peak torque of 320 N m. The total power of the matched motor is 180kW and the total torque is 330 N m. The official acceleration time of zero hundred kilometers is only 4.7s s.

As for the preferential policy of this car, according to the sales introduction, there is no preferential policy for the whole series of Han, but there is a five-year interest-free loan policy, and the store has an existing car. In addition, because Shanghai has just launched a new policy on new energy vehicles, the most influential ones are plug-in hybrid and extended-range models. Therefore, after the release of the policy, Han DM has seen a lot of people.

Of the five models, which one is more worth buying?

BYD Han has five models to choose from, including two for DM and three for EV, so we recommend them separately.

First of all, there are two DM versions, and we recommend the entry-level model with a guide price of 219,800 yuan, which is the luxury model with four-wheel drive performance. In terms of configuration, compared with the four-wheel drive performance version with a guide price of 239,800 yuan, the latter only has more configurations and functions such as leather seats, 4-way height adjustment of the main driver’s seat, 2-way height /4-way waist support of the auxiliary driver’s seat, heating/ventilation of the auxiliary driver’s seat, 11-horn speakers, multi-color interior atmosphere lights, memory/reversing automatic rollover of the external rearview mirror, automatic anti-glare of the internal rearview mirror and independent air conditioning in the rear row. Although the above configuration is worth the price difference, because the configuration of DM itself is high enough, the above additional configuration can not better improve the experience. In the mechanical part, both DM versions are the same. So there is no doubt that DM’s four-wheel drive performance version is a better choice.

Followed by three EV versions, if you like high performance, then directly choose the four-wheel drive high-performance version of the flagship with a guide price of 279,500 yuan. If you have higher requirements for battery life, then choose two long battery life versions. As for these two models, we recommend the entry-level version of EV, that is, the ultra-long endurance luxury model with a guide price of 229,800 yuan. Compared with the super-long endurance version with the guide price of 255,800 yuan, the latter has more parallel assistance, reversing car side early warning system, automatic parking, leather seat, 4-way height adjustment of the main driver’s seat, 2-way height /4-way waist support of the auxiliary driver’s seat, heating/ventilation of the auxiliary driver’s seat, electric seat memory of the driver’s seat, 220V/230V power supply and 11 speakers. Their configuration differences are similar to those of the two DM versions, so the entry version is still the most worth buying.

Write it at the end

To say how hot BYD is, I think the scene where the exhibition hall is full of consumers in the afternoon can prove everything, and the Han series is the representative of it. Super-high face value, spacious space, and full of scientific and technological interior and configuration. Of course, more importantly, it also has DM and EV for consumers with different needs to choose from. It is no wonder that it can be seen everywhere in Shanghai at present.

Herd immunity: Why does herd immunity in English use herd?

This article is reproduced from "A Zewai English Notes" and has been authorized.
At the beginning of the spread of the epidemic in March 2020, the British Prime Minister put forward the proposal of "herd immunity", which made many people feel "refreshing". At that time, the successful development of the vaccine against COVID-19 was still far away, and the British Prime Minister could only imagine the HERD Immunization achieved through "infection of diseases". This proposal with low safety attracted a lot of criticism at that time.
Since the beginning of this year, with the listing of various vaccines, safer herd immunity has become an important means to fight the epidemic. Countries are encouraging people to vaccinate, and strive to reach the vaccination scale needed to realize herd immunity as soon as possible.
Herd immunity will effectively reduce the negative impact of the epidemic and protect people’s health; This statement itself also contains a remarkable feature of English in language and culture, as well as the great differences between English and Chinese.
Before explaining English knowledge, let’s first understand the principle of group immunity.
What’s with Herd immunity?
The definition of Herd immunity is roughly as follows:
Herd immunity is a phenomenon seen when a high percentage of individuals within a population have developed immunity to a pathogen.Group immunity is a phenomenon: in a certain population, a large proportion of people are immune to a certain pathogen (such as bacteria or viruses).
Because so many people within the community are unable to contract the disease or virus, this reduces the likelihood that those who have not developed immunity will contract the disease. Because most individuals in this population have acquired immunity, they will not be infected with related diseases or viruses; In this way, the possibility and risk of exposure to related diseases or viruses will be greatly reduced for those individuals who have not acquired immunity in the whole population.
There are two ways to obtain immunity from a virus or bacteria: infection or vaccination. Comparatively, vaccination is the safer, more effective path, as it provides immunity without illness.
There are two ways to get immunity from a virus or bacteria: one is to infect the disease, and the other is to vaccinate. In contrast, the method of vaccination is more effective and safer, and it will not cause illness while generating immunity.
Different expressions for "group"
In English, there are several other expressions of held immunity, including community immunity, population immunity and social immunity, but in newspapers and media, most articles use the wording of held immunity.
The original meaning of the word herd in English is not used for "people", but to describe "groups of animals".
In practical use, herd mainly refers to cattle, and sometimes also refers to deer or elephants, such as: A herd of cows/deer/elephants and so on.
Using herd to refer to people is strictly an extended metaphor. In addition to newspapers and magazines, people are often referred to in various fictional novels, and the language effect is herd vivid, such as:
She pushed her way through a herd of lunchtime drinkers.
She struggled through the crowd who were having lunch and drinking.
Two idioms
Although the description of "crowd" with herd is vivid and interesting, its meaning is not completely neutral, and it is somewhat disapproving or even critical. It is emphasized that when many people get together, they often lose the ability to think independently as individuals.
Herd mentality or herd instinct, which is often used in English, is usually described as "herd mentality" in Chinese, which means: like flocks of animals and livestock, they have no thinking ability, only know that follow the herd takes action with the whole group; What most other members of the group do, they follow suit.
There is an idiom to ride herd on sb/sth in American English, which is often used to describe crowds. This idiom comes from the plains of the western United States, which reminds people of the scene of cowboys riding horses and herding cattle on the grassland.
Although it originated in the countryside, to ride herd on sb/sth is mainly used in urban areas, which refers to crowd control, usually refers to unorganized crowds, such as:
The police rides herd on crowds of youths on the streets.
The police kept order in the street to prevent groups of young people from getting out of control.
Situation difference
This figurative use of herd to refer to the crowd mainly exists in newspaper articles and literary novels, and is also used in popular science books for the public.
However, in academic articles and official documents of various institutions and departments, most people deliberately avoid using Herd to describe people. For example, in academic and formal occasions, herd immunity is usually replaced by community immunity and population immunity.
Although this will reduce the vividness of the language, it can rule out the possibility of association and avoid being offended. Although it is vivid, it is more objective and accurate.
cultural difference
Different from English culture, many other languages and cultures are not used to using words specially used to describe animals to describe human beings, and even are very taboo about it. This is the case in Chinese, and an obvious example is a large number of insulting expressions in traditional Chinese that originated from "dogs".
This cultural difference between Chinese and English deserves special attention when learning and using English. When translating English-quoted media articles, it is especially important to realize that when "animals" are used to describe "people" in English, they are usually not insulting, and they are not intentionally offending others and calling them "animals, pigs and dogs are inferior".
Most of the time, Herd’s analogy of "animal" to "human" can be directly translated into plain language without rhetorical meaning.
Two more "groups"
Realizing the cultural differences between Chinese and English in animal metaphor can also help us to use English more vividly and effectively, and we will not be timid because of this "burden" of traditional Chinese rhetoric expression.
English words like herd, which use animals to describe "people", are very rich and constitute a systematic series.
For example, herd is suitable for cattle, deer, elephants and other large animals; The "flock" of smaller animals is called flock in English, which mainly refers to sheep.
In addition, flock can also refer to a flock of birds, such as the proverbial birds of a feather flock together, which often corresponds to the Chinese word "birds of a feather flock together". When describing insects, such as bees, it will be called swarm.
Like herd, flock and swarm are often used to describe people, which not only remind people of vivid images, but also have their own division of meaning and function, describing different characteristics and aspects of "group behavior" respectively. In English, these statements are usually not regarded as insulting or demeaning.

Nearly 60% of China’s demand for intelligent computing power comes from large models. How will the "gold" GPU chip play a greater role? | Silicon-based world

NVIDIA H100 Tensor Core GPU (Source: NVIDIA)

In the era of artificial intelligence (AI) big model, computing power plays an increasingly important role and becomes a key productivity.

On December 20th, Titanium Media App recently learned from the first "AI Tech Day" conference that the report "White Paper on the Development of Intelligent Computing Industry in China in 2023" released by iResearch showed that the demand for large-scale model computing power broke out in 2023, and the industries related to AI large-scale model accounted for 58.8% of the total demand for intelligent computing power in China, close to 60%, which was the largest demand side of intelligent computing power. The second place is algorithm recommendation, accounting for 14.2%.

The report also shows that in 2022, the scale of intelligent computing power will account for 22.8% in China’s computing power structure, but in the same period, the shipment of AI servers will only account for 6.8% in China’s server structure. This means that intellectual computing resources are scarce, and the construction of intellectual computing center will effectively improve the supply and demand structure of intellectual computing resources in China.

Xu Fanlei, head of iResearch Industry Digital Research Institute, said that in the future, the general artificial intelligence (AGI) technology will continue to develop, which will promote the overall demand for intelligent computing. Therefore, it is necessary to have enough high-end intelligent computing power and constantly optimized software and hardware integration solutions, as well as to build ecological convergence upstream and downstream, full chain, and participants in various fields, and the use threshold is low and convenient enough.

In fact, over the past year or so, the generative AI technology represented by ChatGPT has been popular all over the world. Nvidia, which monopolized the global Al training chips with 95% market share, became the biggest winner of this round of AI melee, and its research and development of A100/A800, H100/H800 and other AI chips became the "explosive products" in the AI craze.

As NVIDIA itself said: "GPU has become a rare metal of artificial intelligence, even gold, because they are the foundation of today’s generative AI era."

From a technical point of view, GPU is superior to CPU, especially in parallel computing power, energy efficiency and CUDA ecology. Its high computing power and scalability make NVIDIA GPU the first choice in the AI accelerated chip market.

According to a recent report released by Stanford University, since 2003, the performance of GPU has increased by about 7000 times in the past 20 years, and the unit performance price has also increased by 5600 times. The report also pointed out that GPU is the key driving force to promote the progress of AI technology.

Nowadays, computing power is accelerating the evolution of applications in government affairs, industry, transportation, medical care and other industries, promoting the deep integration of the Internet, big data and artificial intelligence with the real economy, and greatly stimulating the innovation vitality of data elements.

According to public data, since 2018, the compound annual growth rate of the number of racks in China data center has exceeded 30%. By the end of 2022, there were more than 6.5 million standard racks in use. According to the calculation of China Information and Communication Research Institute, in 2022, the scale of the core industry of computing power in China will reach 1.8 trillion yuan, and every investment in computing power in 1 yuan will drive the economic growth of GDP from three to 4 yuan.

Then, with the increasing demand for AI models in China, the gap of NVIDIA’s GPU computing chips reaches 432,000 pieces. So, how will the "golden" GPU chips play more space?

At the first "AI Tech Day" meeting of InBev Mathematics Department held on December 18th, InBev Mathematics Department announced a strategic upgrade, from positioning a large model computing service provider in stage 1.0 to positioning an "AGI full-stack ecological service platform" in stage 2.0-providing a series of computing and full-stack solutions including IaaS infrastructure layer, PaaS platform layer, data engineering service, data store and model store for customers in the entire industrial chain of AGI, forming a "full-stack solution". In addition, InBev Mathematics Department has also launched "Bobo Cloud" service, as well as commercial landing projects such as "AGI Pan-Entertainment Alliance", "Wutong Project" and "MM Bean Project".

According to public information, Hongbo shares is a listed company whose main business is bill printing, but InBev Digital Branch, a wholly-owned subsidiary of NVIDIA’s server product supply, was established a year ago, and then Hongbo shares became a "computing power" concept stock and its share price soared.

On August 10th, 2022, Hongbo Co., Ltd. signed a four-party cooperation agreement with Zhongguancun Zhongheng Cultural Science and Technology Innovation Service Alliance, Nvidia Company and Beijing InBev Digital Technology Co., Ltd. to establish the "Beijing AI Innovation Empowerment Center". InBev Digital, a wholly-owned subsidiary of the company, is the main body of the "Beijing AI Innovation Empowerment Center".

On December 4th this year, Hongbo shares disclosed a major contract announcement, and InBev Digital recently signed a Cloud Service Agreement with Baichuan Intelligent, founded by Wang Xiaochuan. During the agreement period, InBev Digital provided the latter with services such as high-performance computing or GPU computing technology. The total transaction amount involved in the agreement is estimated to be 1.382 billion yuan.

Zhou Wei, vice president of Hongbo Co., Ltd. and CEO of InBev Mathematics Department, said that the development from AI to AGI requires deep interdisciplinary integration. The company should not only build a one-stop service ecological closed loop, but also gather the top technical partners in China and even the world through this ecology, focusing on finding innovative computing solutions on the hardware side and data, model and algorithm optimization and upgrading solutions on the software side, thus relying on the single brand path of high-end intelligent computing equipment at this stage.

"Take a service provider who serves 15-20 small and medium-sized customers every year as an example. Through the calculation service fee and the sales rebate of Boboyun’s value-added service fee, combined with resource locking tools such as prepaid leverage, it is roughly calculated that every year (customers) can achieve gross profit income of hundreds of thousands." Zhou Wei said.

It is reported that the minimum computing power rental unit that InBev Mathematics Department will provide is a complete server, with a minimum lease term of 3 months. Each machine is charged separately every month, and the rent is paid monthly in advance. The target customers include AI technology companies that have a large demand for intelligent computing power, such as multimodal large model training and development, cloud rendering, driverless reasoning, and quantitative trading model training. Taking a single monthly computing service of H800 as an example, the pricing of computing power for strategic partners is 96,000 yuan p.u/m, and the potential customers are 256,000 yuan p.uhttps://m.jrj.com.cn/madadapter/finance/2023/12/m.

Up to now, InBev’s partners include head companies such as Baichuan Intelligent, MiniMax, Luchen Technology, Wuxinxin Dome, Jingneng International, Anqing Computer, ProLogis, iSoftStone, Century Internet, Zhongke Langke and Chinese Online, as well as chip leaders such as NVIDIA, Intel and AMD.

"We want to make computing power more efficient and universal, like water and electricity." InBev Mathematics Department said.
