In 2023, the first adjustment of domestic oil prices will rise; Will there be a wave of price increases for mainstream car companies early next year？

1. In 2023, the first adjustment of domestic oil prices will rise.

According to the domestic refined oil price adjustment rules, a new round of refined oil retail price limit adjustment window will open at 24: 00 on January 3, 2023. As of December 27th, on the 6th working day, with reference to the crude oil change rate of 4.87%, it is predicted that gasoline and diesel will be raised by 275 yuan/ton, and after conversion, it will be raised by 0.21-0.24 yuan/liter. At present, the 4 cents that fell only last week has increased by half. According to this calculation, it will cost about 10.5-12 yuan to fill a tank with a capacity of 50L.

The date of price adjustment (24: 00 on January 3) is getting closer and closer, and downward adjustment is impossible. Oil prices will usher in the "first price increase" in 2023, and riders can refuel in advance.

2. Will there be a price hike for mainstream car companies early next year?

In order to seize the last wave of policy dividends, a group of new energy vehicle companies launched an unprecedented limited-time insured promotion war when the "state subsidy" entered the countdown. According to incomplete statistics, since November, more than 20 car companies have successively introduced time-limited insurance policies: some car companies have adopted the method of "locking orders before the year, paying a deposit and enjoying state subsidies in 2022", while others have played a combination boxing scheme of "insurance within the year+price increase after the year". Among them, BYD, which has completed the annual sales target of 1.5 million vehicles ahead of schedule, took the lead in launching the "first shot" of price increase.

In the price increase statements of various car companies, "the subsidy policy for the purchase of new energy vehicles will be terminated on December 31, 2022, and the countries that have licensed vehicles will no longer give subsidies" and "the prices of major raw materials such as batteries continue to rise sharply" are two essential reasons. In recent years, the continuous high sales of new energy vehicles directly boosted the growth of lithium battery loading. However, the explosive growth of terminal demand has caused the price of lithium material, which is an important raw material for vehicle power batteries, to soar. From the low price of 41,000 yuan/ton in June 2020 to the high price of 537,500 yuan/ton on October 18, 2022, the price of battery-grade lithium carbonate rose by more than 12 times, up by more than 8 times compared with the beginning of last year.

According to the analysis of Cui Dongshu, secretary-general of the Association, the net profit rate of lithium mine business of leading enterprises is around 70% this year, and the profit rate of power battery enterprises is around 8%, but the profit rate of vehicle enterprises is only around 5%. Obviously, the rising prices of raw materials have directly squeezed the profits of car companies. Therefore, in the context of the withdrawal of "state subsidy", I am afraid that more new energy vehicle companies will join the price increase camp in 2023.

3. Weimar Automobile was applied for freezing property.

Weimar Automobile, once one of the "Four Little Dragons", a new force to build cars, is living in the dilemma of "lack of money". From the aggravation of losses to internal salary reduction, from the power lock-up storm to the decline in sales, coupled with the IPO being blocked and patent compensation … Weimar Automobile was particularly cold this winter, but unfortunately it did not stop there.

Recently, Anji Zhixing Logistics Co., Ltd. and Weimar New Energy Automobile Sales (Shanghai) Co., Ltd. and Weimar Automobile Technology Group Co., Ltd. made public the non-litigation preservation review ruling. According to the documents, the applicant Anji Zhixing Logistics Company requested the court to seal up and freeze the property of the respondent Weimar Company and Weimar Company worth 76.52 million yuan. The court held that Anji Zhixing Logistics Company’s application was in compliance with the law and was ruled to be executed.

However, it is noteworthy that Weimar Automotive Technology (Sichuan) Co., Ltd. has recently undergone a number of industrial and commercial changes, with its registered capital increased from 170 million yuan to 520 million yuan, its legal representative, executive director and manager changed from Freeman Shen to Wei Wei, and Mianyang Anzhou Investment Holding Group Co., Ltd. became the new shareholder of the company. I wonder if the blessing of the state-owned party will bring a new situation to Weimar Automobile?

4. Or introduce new models, and expose the product planning of GAC Toyota.

On December 21st, the fifth plant of GAC Toyota New Energy Vehicle was officially put into operation, with an annual production capacity of 200,000 vehicles. Then on December 26th, GAC Toyota officially reached the milestone of annual output of 1 million units. A few days ago, some domestic media exposed the production plan of the fifth factory. The 200,000 new cars in the new factory are all new energy products. In addition to the confirmed pure electric medium-sized SUV bZ4X, there will be brand-new SUVs and MPV models.

According to Toyota’s recent product planning, the SUV model may be the Grand Highlander which will be launched in February next year. The MPV model is still mysterious, because there is no pure electric MPV product in Toyota’s planning. In addition, the sixth plant of GAC Toyota may also be planned, and it is expected to start construction in 2023 and officially put into production in 2025.

5. Land Rover Defender Special Edition sold 898,000, and 130 pre-sold 1.198 million.

2023 is the 75th anniversary of the Land Rover brand. To celebrate this milestone, Land Rover launched the legendary version of the 75th anniversary of Defender, and the prices of the two models were 898,000 yuan and 958,000 yuan respectively. This car continues the design of the ordinary version and introduces the iconic Grassmill green to commemorate the Land Rover Series I launched in 1948.

At the same time, the Guardian 130 also started the pre-sale, offering two models with optional extended light kit and off-road kit, with a pre-sale price of 1.198 million yuan. The new car can be regarded as an extended version of the 110, with a length of 5100mm and a wheelbase of 3022mm, and an eight-seat layout of 2+3+3 is adopted in the car. The power is equipped with a power combination of 3.0T six-cylinder double supercharged engine and +48V light mixing.

6. Starway Eta Ursae Majoris made its debut and started blind booking.

Star Road Eta Ursae Majoris officially appeared and opened a blind subscription, with a price range of 170,000-220,000 yuan. The new car is based on Starway M3X Mars Architecture 2.0, with a length of 4781mm and a wheelbase of 2815mm, and is positioned as a medium-sized SUV. In terms of appearance, the grid with borderless style, the through LED strip and the dot-matrix light groups in the fog lights on both sides increase the recognition of the whole vehicle. From the side of the car body, a sporty coupe SUV shape is adopted. A large number of horizontal lines are used at the rear of the car, and the penetrating taillights further stretch the visual width of the tail.

The interior design is simple and fashionable, equipped with a 24.6-inch curved dual screen, built-in Qualcomm 8155 intelligent cockpit chip and Horizon J3 driver-assisted chip, which supports functions such as WHUD, ARHUD and 50W mobile phone charging. The power is equipped with a 2.0T engine and matched with a 7-speed dual-clutch gearbox.

7. Weilai will sell more than Lexus next year.

Li Bin, the founder and chairman of Weilai, said in an exclusive interview with the media in Weilai, 2022 that 2023 will be the year when the sales of the second-generation platform will be released, and three new cars will be released next year. It is expected that the overall sales potential of the second-generation platform will be seen in the fourth quarter of next year. The internal sales target for next year is to exceed the sales of Lexus fuel vehicles. Qin Lihong, president of Weilai, said that there was "little pressure" to achieve this goal.

The data shows that from January to November this year, Weilai Automobile delivered a total of 106,700 new cars. Lexus’s performance has declined this year, with a cumulative sales volume of 168,600 vehicles from January to November. There is a gap of more than 60,000 vehicles between them. Judging from the sales volume of 227,000 vehicles of Lexus in China in 2021, the sales volume of Weilai Automobile will reach 19,000 vehicles at least every month. Weilai has obvious advantages among competitors at the same level, and has attracted a large number of loyal fans. As for whether Li Bin’s statement that "the sales volume will definitely exceed the sales volume of Lexus fuel vehicles next year" can be achieved, we may wish to wait and see.

8. Two-door and four-seat layout, Geely Panda mini will be unveiled soon.

We learned from the official that Geely Panda mini will be unveiled at the Guangzhou Auto Show, which will open on December 30th. As a brand-new micro electric vehicle, the new car is small and cute, and it is more cute with a round headlight group. In terms of size, the length of the car is 3065mm, the wheelbase is 2015mm, and the layout of two doors and four seats is adopted. According to the application information, the car will be equipped with a 30kW motor and a lithium iron phosphate battery provided by Guoxuan Hi-Tech, with a pure electric cruising range of about 200 kilometers.

The market segment of mini pure trams has become another strategic goal of various car companies. As for whether Geely Panda Mini can be recognized by the market, it depends on whether it can match the price range accepted by consumers.

Snooker Scottish Open： Ding Junhui stopped in the top 32 and Lv Haotian advanced to the top 16.

China news agency, Beijing, December 14 th On the morning of the 14th Beijing time, the 2023 Scottish Open ended the contest on the third day of the race. In the 32-round and 16-round competitions, China billiards star Ding Junhui suffered a lore and stopped at the top 32. Another China player, Lv Haotian, took the lead in advancing to the top 16.
Ding Junhui and English star tom ford competed for a place in the top 16, which was one of the focus battles of the day’s competition. Before this, the two sides confronted each other many times, and Ding Junhui occupied an absolute advantage. Among them, in the semi-finals of last season’s British Championship and 6 Red Ball World Championships, Ding Junhui defeated his opponent and advanced to the final. Ding Junhui defeated tom ford again in the quarter-finals of the British Championship that ended a few days ago and advanced to the quarter-finals. However, after winning the runner-up in Tianjin International Championship last month, tom ford once surpassed Ding Junhui in the world ranking.
This time, when they met their old enemies again, both sides were tit for tat, and the first six games were tied at 3-3. In the deciding game, tom ford seized the opportunity and scored 81 points in a single shot to seal the victory. At the same time, he succeeded in "revenge" and replaced his opponent to advance to the top 16. Prior to this, Ding Junhui had suffered a "champion shortage" in the ranking competition for more than four years, and this defeat delayed his goal of winning the 15th championship in the ranking competition again.
In the 32 rounds and 16 rounds, three players from China appeared. Among them, Pang Junxu lost to Scottish star anthony mcgill 2-4; In a "Chinese Derby", Lv Haotian defeated 19-year-old Liu Hongyu 4-2, becoming the first China player to advance to the top 16 in this competition.
On the same day, in the first 64 rounds of 32 rounds, three China "post-00" teenagers won 1 and lost 2-Si Jiahui, a top four player in last season’s World Championships, defeated Belgian Julian Leclere 4-2, becoming the seventh China player to advance to the top 32 in this competition. 19-year-old Xing Zihao lost to gary wilson 3-4, and Yuan Sijun lost to Sam craigie 0-4, so they went out hand in hand.
Brecel, ranked fourth in the world, and Selby, ranked fifth in the world, both stopped in the top 32. So far, the top eight players in the world have missed the top 16 in this Scottish Open. Except for O ‘Sullivan, who ranked first, who retired temporarily, and neil robertson, who ranked sixth, who didn’t sign up for the competition, the other six famous players were eliminated in the first three days.
On the next match day of this Scottish Open, Zhang Anda and Si Jiahui will bring another "Chinese Derby" in the final battle of 32 rounds and 16 rounds; Zhou Yuelong, who won because his opponent retired in the first round of the race, will face British veteran andrew Higginson. (End)

treat life as merely playing games

Although I am getting older, my former students have begun to step into the society and plan their own lives, but my love for games has never faded.

　　In my spare time, I turn on my computer, log in to the game, and run my own small world in a virtual space. World of Warcraft, an old game, although there are too many sorrows in the national costume of the DPRK on this day, all this is just a place of spiritual sustenance for a casual player.

　　People often ask, at this age, you still play games, just like a child. Yes, in fact, I just hope that I can do whatever I want, just like a child, without too much scruples.

　　In fact, in the game, compared with other people’s efforts to make copies, playing the arena seriously and running all over the sky, what I like is just a quiet fishing by the river, watching the falling fishing rod and clicking when taking the bait, all of which bring me great happiness. Many friends in the game don’t understand why I spend my time fishing calmly in a virtual world, and ironically, I have no interest in fishing in reality. I sometimes wonder why I am so interested in a virtual fishing game.

　　Every time a fishing rod falls, it carries an expectation that something you like will be hooked, and there is a slight expectation in your heart;

　　Every click on the hook is a realization of expectations. Although disappointment accounts for the vast majority, that little satisfaction is the greatest happiness of this click.

　　Life is not so bad, every day is full of hope for your future, and you keep working hard in the passage of time. The reality has always been in front of us. He told us again and again that it is not necessary for you to work hard to gain something, so we repeated the rising and falling of the stars in the morning again and again, and kept advancing in the failure again and again for the ideal in our hearts, and one day we will realize this dream.

　　The game, life, the dribs and drabs in the game, the subtleties in life, one’s own grasp and persistence, and that little bit of luck are all an experience.

4 years, 54 million, pay cut and return to the Lakers! Ham publicly praised James as your big brother.

There are still many players in today’s league. Their starting point is not high, and they almost missed the opportunity to land in the NBA. However, with their step-by-step efforts, they gradually shine on the court. Among the active NBA players, which one impressed you the most? Some fans may choose Van fleet. Van fleet’s physical condition is not excellent, and his height is only 1.83 meters. This kind of small defender is hard to be favored by the team. However, at the age of 29, he has now grown from a draft player to an all-star player. He won a championship trophy with the team and has been the core of the Raptors for several seasons. It is really not easy. This offseason, Van fleet was poached by the Rockets, and signed a three-year super contract worth 130 million US dollars, completely playing his own value.

Wood, the core of the inside attack of the Lone Ranger, is also a draft loser. Up to now, his average score can reach 15 points per game. Although Wood, as an inside player with little functionality, only focuses on offense, and lacks some blue-collar attributes, this summer Wood is still one of the most sought-after players in the free market. After ending his contract with the Lone Ranger, Wood will look for his next home, reportedly including Bulls. In addition to Van fleet and Wood, like Vincent, Struce and Dunrow who entered the finals with Miami Heat this year, Stephen Curry’s younger brother Kokuri, and caruso, the former "mascot" of the Lakers, they all entered the NBA as draft losers.

There is also Reeves of the Lakers. After caruso left the Lakers, Reeves was regarded as his successor, and the second generation of the Lakers’ mascots was born. They have a lot in common, the same skin color, both of whom are draft losers, the players are very high, and they are all right-hand men around James. During the period when Reeves first came, many Lakers fans felt that he and caruso were still not comparable. After all, there was still a big gap in their physical fitness, and the defensive end was not at the same level at all. caruso’s defense was really fierce. However, after playing for a season, Reeves has made rapid progress and is more suitable for the current old Zhan. James is almost 39 years old now, and his playing time and possession of the ball will be reduced. Reeves’ organization and attacking with the ball can just share a lot of pressure for James.

On the offensive end, Reeves is one step ahead of caruso, and his three-point shooting is one of the most stable in the Lakers, with a shooting percentage of 40%. It’s no problem for old Zhan to match caruso in 19-20 seasons, but now James needs players like Reeves even more. During the offseason this summer, Reeves also faced the problem of contract renewal. His last contract was only two years’ basic salary, with an average of more than one million dollars a season. Now, Reeves has made his mark. According to Stein, a well-known journalist, Reeves can sign a contract with a maximum of 100 million dollars for four years during the offseason, and the Spurs also offered him a big contract with an average of more than 21 million dollars per season, but in the end, Reeves chose to stay with the Lakers.

The Lakers reached a four-year $54 million renewal contract with Reeves, with an average of less than 14 million a year, which is much less than the price offered by other teams. In four years, it was 54 million, and the salary was reduced to return to the Lakers! Hamm publicly praised James as your big brother. Reeves said, "I want to stay with the Lakers.". For me, this is like home. I definitely want to stay with the Lakers. My teammates, coaches and management are very supportive. " In fact, Reeves himself knows that he can get a better platform and resources by staying in a traffic brigade like the Lakers, and even get "special treatment" in the game, making it easier to play his own worth. Lakers coach Hamm publicly praised Reeves: "He is excellent, and he will soon grow into an all-star player."

Old Zhan is of course the happiest to keep Reeves, because the cooperation between them is very tacit, and James often teaches Reeves’ competition experience. Reeves spoke highly of the team’s eldest brother James: "You never want to see a player like that not playing, just because he is so outstanding. Since he was selected in 2003, he has been almost a signature figure in the league, and I really hope to play with him." Speaking of old Zhan’s character, Reeves said: "He acts like a child, as if he were 18 years old. I have never seen him in a bad mood. He is always laughing and having fun. Because of his brilliant achievements, for such a person who is placed on the altar, he can be so approachable, you can discuss anything with him, you can have great communication with him, and you can joke with him at will. "

Reeves can continue to cooperate with Zhan in the new season. Do you think he is expected to hit the All-Star in the future?

Aunt Guangdong plays mahjong ten times and nine times to win! Won more than 70 thousand in six months. How did she do it？

Recently, a woman in Guangdong was playing.mahjongI won nine out of ten and won more than 70,000 yuan in six months.

After you get to know them from the shallow to the deep, I will teach you some common routines of playing cards and some tips of card line analysis.

If you want to master a skill, then it is essential to have a theoretical foundation. Why do some people play mahjong all their lives, or are they said to play cards at random? It is because in the early theoretical study, I didn’t lay the foundation, set up the correct thinking of playing cards, and didn’t have a correct understanding of mahjong tiles.

If you want to play mahjong well, instead of simply joining in the fun, then I strongly recommend this book, which not only explains how to play mahjong for you. At the same time, it also straightened out your thinking of playing cards in the future, that is, helped you lay a solid foundation in the early stage.

Compared with many online gossips, this book is more authoritative, systematic and comprehensive. And summed up the playing methods of most kinds of mahjong cards in China, whether you want to learn southern mahjong or northern mahjong? The tutorials in it are all available.

China football misunderstood you？ At the age of 26, the national football team lost a lot after being naturalized and restored to its original nationality.

China football spent a lot of money to introduce naturalized players during the Jin and Yuan football periods. Now some naturalized players have left China to restore their original nationality after receiving the money, and even some naturalized players have not made one appearance for the national football team. Recently, a former naturalized national football player returned to his original nationality and scored a goal in seconds. Have to let China football doubt his true ability.

The former naturalized football player in China is Xiao Taotao, who has recovered his Peruvian nationality and now plays for Peru Sports University. After returning to Peru, Xiao Taotao seems to have greatly increased his strength. He has already contributed one goal to the team. The club also regards Xiao Taotao as a key player. However, he has never even played in the Super League in China before, and is regarded as one of the most unsuccessful naturalization by China football.

After being naturalized by Evergrande, Xiao Taotao’s strength has not been fully recognized. Even when he was loaned to play football in China, the national team looked down on Xiao Taotao. Until he left China, he was not recognized by the national team and never got a chance to play for the China team. However, during his four years in China, he earned a lot of money, and Evergrande gave him an annual salary of 12 million RMB.

In 2019, Xiao Taotao played for Shenxin in Shanghai, China. He started in 5 of 10 games and scored 1 goal. In the 2020 season, there were only 6 appearances for Kunshan, of which 3 started with 0 goals; In 2021, he made 21 appearances for Kunshan, including 12 starts and scored 2 goals. These goal data show that Xiao Taotao’s strength is really not enough to enter the national football team.

However, Xiao Taotao scored a goal very quickly after returning to Peru, which surprised us a little. He himself said that he was very happy after returning to Peru and thanked his old club for not giving up on him. (Qianzi)

Technical password of generated image AI

In the past few years, artificial intelligence (AI) has made great progress, and AI’s new products include AI image generator. This is a tool that can convert input statements into images. There are many AI tools for text-to-image conversion, but the most prominent ones are DALL-E 2, Stable Diffusion and Midjourney.

DALL-E 2 is developed by OpenAI and the project of chatgpt is complementary. It generates images through a paragraph of text description. Its GPT-3 converter model trained with more than 10 billion parameters can interpret natural language input and generate corresponding images.

DALL-E 2 mainly consists of two parts-converting user input into a representation of an image (called Prior), and then converting this representation into an actual photo (called Decoder).

The text and images used in it are embedded in another network called CLIP (Contrast Language-Image Pre-training), which is also developed by OpenAI. CLIP is a neural network that returns the best title for the input image. What it does is the opposite of what DALL-E 2 does-it converts images into text, while DALL-E 2 converts text into images. The purpose of introducing CLIP is to learn the connection between visual and text representation of objects.

DALL-E 2′ s job is to train two models. The first one is Prior, which accepts text labels and creates CLIP image embedding. The second is Decoder, which accepts CLIP image embedding and generates images. After the model training is completed, the reasoning process is as follows:

  • The input text is converted into CLIP text embedding using neural network.

  • Use Principal Component Analysis to reduce the dimension of text embedding.

  • Create an image embedding using text embedding.

  • After entering the Decoder step, the diffusion model is used to embed the image into an image.

  • The image is enlarged from 64×64 to 256×256, and finally enlarged to 1024×1024 by using convolutional neural network.

Stable Diffusion is a text-to-image model, which uses CLIP ViT-L/14 text encoder and can adjust the model through text prompts. It separates the imaging process into a "diffusion" process at runtime-starting from the noisy situation, gradually improving the image until there is no noise at all, and gradually approaching the provided text description.

Stable Diffusion is based on Latent Diffusion Model(LDM), which is a top-notch text-to-image synthesis technology. Before understanding the working principle of LDM, let’s look at what is diffusion model and why we need LDM.

Diffusion Models, DM) is a generation model based on Transformer, which samples a piece of data (such as an image) and gradually increases the noise over time until the data cannot be recognized. This model tries to return the image to its original form, and in the process, it learns how to generate pictures or other data.

The problem of DM is that powerful DM often consumes a lot of GPU resources, and the cost of reasoning is quite high due to Sequential Evaluations. In order to train DM on limited computing resources without affecting its quality and flexibility, Stable Diffusion applies DM to powerful Pre-trained Autoencoders.

On this premise, the diffusion model is trained, which makes it possible to achieve an optimal balance between reducing complexity and preserving data details, and significantly improves the visual reality. The cross attention layer is introduced into the model structure, which makes the diffusion model a powerful and flexible generator and realizes the high-resolution image generation based on convolution.

Midjourney is also a tool driven by artificial intelligence, which can generate images according to the user’s prompts. MidJourney is good at adapting to the actual artistic style and creating images with any combination of effects that users want. It is good at environmental effects, especially fantasy and science fiction scenes, which look like the artistic effects of games.

DALL-E 2 uses millions of image data for training, and its output results are more mature, which is very suitable for enterprises to use. When there are more than two characters, the image generated by DALL-E 2 is much better than that generated by Midjourney or Stable Diffusion.

Midjourney is a tool famous for its artistic style. Midjourney uses its Discord robot to send and receive requests for AI servers, and almost everything happens on Discord. The resulting image rarely looks like a photo, it seems to be more like a painting.

Stable Diffusion is an open source model that everyone can use. It has a good understanding of contemporary art images and can produce works of art full of details. However, it needs to explain the complex prompt. Stable Diffusion is more suitable for generating complex and creative illustrations. However, there are some shortcomings in creating general images.
