The Survival Differences between Jia Baoyu and Jia Yun

A Study on the Original Lanji Culture Dream of Red Mansions

author

Return home like a rainbow

In the sixth episode of A Dream of Red Mansions, Wang Xifeng said to Grandma Liu, "As the saying goes, there are three poor relatives in the imperial court, not to mention you and me". Wang Xifeng is really not posturing in front of Granny Liu. The Jia family really has poor relatives, and Jia Yun is one of them.

In the twenty-fourth chapter, Jia Baoyu saw Jia Yun who was "gentle and delicate" and felt "very kind". Jia Baoyu has always disliked contact with men with beards, but he has a good impression on Jia Yun. After all, Jia Yun’s image is in line with Jia Baoyu’s aesthetics.

However, Jia Baoyu did not recognize Jia Yun, but Jia Lian reminded him that Jia Yun was "the son of the fifth sister-in-law who lived on the back porch".

The world has always been divided, and the living conditions between people have always been very different. Jia Baoyu and Jia Yun are both descendants of the Jia family. Jia Baoyu is the "darling" of the Jia family and the "phoenix" in the Jia family. He lives in love with thousands of people, while Jia Yun lives alone with his mother and has a hard life. Jia Yun is a relative of Jia Baoyu, but they live in two different worlds, so that Jia Baoyu doesn’t recognize Jia Yun.

Although Jia Baoyu is four or five years younger than Jia Yun, he is Jia Yun’s uncle. Therefore, Jia Baoyu said to Jia Yun in a joking tone, "You are more picky than before, and you look like my son." As a result, Jia Yun, who was quick and quick-witted, conveniently recognized Jia Baoyu as his "father".

In the 25th chapter, Jia Baoyu and Wang Xifeng were framed by Aunt Zhao and Ma Daopo, and their lives were hanging by a thread. Jia Yun guarded Jia Baoyu day and night, "working hard for several days". Jia Baoyu, the "father", did not do anything for Jia Yun, the "son", but Jia Yun did his best to protect Jia Baoyu. It can be seen that Jia Yun is very filial and responsible, and really cares about Jia Baoyu, the recognized "father".

In the 26th chapter, Jia Baoyu and Jia Yun had a "casual conversation". The content of the conversation is completely the life of a dude led by Jia Baoyu: "He also said whose actor is good and whose garden is good, and told him whose maid is beautiful, whose banquet is rich, who has exotic goods and who has foreign objects." These lives are something Jia Yun has never experienced. Jia Yun doesn’t have the capital to enjoy life. He is a child of poor families. If he wants to survive, he must try his best to seize the opportunity.

Jia Yun is not as well-fed as Jia Baoyu, nor can he live so exquisitely, poetically and romantically like Jia Baoyu. After his father’s death, he quickly felt the warmth of human feelings and the coldness of the world. In order to get a job in Wang Xifeng, he turned to his uncle for help, and all he got was bitter sarcasm. In order to take care of his mother’s mood, he didn’t reveal the humiliation he felt at his uncle in front of his mother. Unlike Jia Baoyu, Jia Yun can have a young master’s temper and be carefree, because he knows too much about the difficulty of survival and the complexity of human feelings.

Jia Yun can’t have no economic mind like Jia Baoyu, and he doesn’t even know money. He is pragmatic and sophisticated. The money that Jia Baoyu disdains is extremely important to Jia Yun. For Jia Yun, what Jia Baoyu despises is that "everything is learned when the world is clear, and people’s understanding is an article" is the way to survive. Therefore, he can bribe Wang Xifeng for work. For Jia Yun, this is not shameful, but a need for survival. Lofty is what people like Jia Baoyu who don’t know the hardships of life value, and it is not what Jia Yun needs to insist on.

Jia Yun is not as rich in poetry as Jia Baoyu, and he is not as excited as Jia Baoyu because Jia Tanchun invited him to join the poetry club. He gave him two pots of Bai Haitang to be filial to Jia Baoyu, and at the same time wrote a copybook with no literary talent. He can’t walk into the elegant cultural circle of Jia Baoyu and others, so he can only try his best to express his feelings for Jia Baoyu. Bai Haitang can make Jia Baoyu and their poems flourish, which is a part of Jia Yun’s work.

However, Jia Yun can also boldly pursue his own love. Of course, the love between him and Xiaohong can’t be as touching as Baodai’s. Jia Yun and Xiaohong are both rich in human fireworks, and they are both good at seeking opportunities for themselves by eloquence. Therefore, the love between them is also full of human fireworks.

Xiaohong originally intended to win Jia Baoyu’s favor, but she was disheartened by the ridicule and exclusion of Qiu Wen and others. So she changed her goal. She and Jia Yun fell in love with each other after several eye-catching. They can’t write touching love poems, nor can they say thrilling love words, but they convey their affection to each other with handkerchiefs.

People like Jia Baoyu who have no pragmatic spirit and ability can’t survive after the downfall of Jia’s family. At that time, people like Jia Yun who know how to survive and are grateful will be particularly important. Without Jia Yun who fought bravely, Jia Baoyu probably couldn’t even live, let alone pursue spiritual liberation.

Jia Baoyu and Jia Yun represent two living conditions: Jia Baoyu pursues spiritual freedom and emotional satisfaction; Jia Yun pursues the living space according to the secular rules. Jia Yun’s lifestyle is naturally closer to our ordinary people. After all, most people in this world can’t be rich and idle like Jia Baoyu. Jia Baoyu will not be a rich and idle person one day, and it is not easy to truly appreciate Jia Yun.

What is rare is that Jia Baoyu has never looked down on Jia Yun because of the huge difference between him and himself. This is the lovely place of Jia Baoyu. What’s more, Jia Yun never belittled himself in front of Jia Baoyu because of poverty. In A Dream of Red Mansions, they are the clean stream in the turbid things.

  Ji zhi Jia yue technology

  As a perfect interpreter of Honda FUNTEC technology, the ninth-generation Accord has been built by the engineers of Honda F1 racing design team, and the application of a number of racing technologies has achieved top aerodynamic performance and further improved fuel economy.

  The ninth-generation Accord is not only an upgrade of advanced configuration, but also an all-round innovation of vehicles from body, chassis and suspension: the combination of front suspension with EPS electronic system and independent rear suspension brings the integrated handling performance of people and vehicles, which not only greatly improves comfort, but also realizes strong driving stability, perfectly unifying accurate road feeling and comfortable driving experience.

  The ninth-generation Accord adopts the advanced compatibility of the new-generation ACE. On the basis of the eighth-generation Accord, which is already a safety benchmark at the same level, the proportion of high-strength steel is increased to 49%. In the most stringent American (American Highway Safety Insurance Association) crash test, the ninth-generation Accord beat many popular models and won the honor of "the safest model of 2013". At the same time, the ninth-generation Accord comes standard with vehicle stability control system, EPB braking system, HSA slope starting auxiliary system and ABH system, and is also the first to carry Honda’s advanced safety technologies that can effectively prevent collisions: LWC blind spot display system can effectively monitor the blind spot of the right rearview mirror when turning; ACL lighting system can automatically illuminate the turning area when turning in dark environment; The collision mitigation braking system and ACC active cruise control system, which are specially equipped for China consumers, make use of the distance between the radar installed on the car head and the preceding car to make adjustments and give early warning actively, thus providing peace of mind.

  China yuanchuang, from "synchronization with the world" to "synchronization with the world"

  As a practitioner of Honda’s innovative spirit and the world’s leading technology, Accord has always adhered to the vertical replacement and continuous evolution with the world since it was introduced to China. Since entering China for 15 years, we have always set new industry standards with many pioneering and leading technologies. Accord is not only synonymous with high sales volume, but also a leader in the middle and high-end auto market.

  Today, China has become the largest and most competitive automobile market in the world. Facing the huge base and diversified demand of China consumers, it is difficult to fully meet the increasing demand of China consumers for cars by directly introducing global models into the China market. Guangqi Honda has a keen insight into this change, which not only changes the mode of importing overseas models directly into the China market, but also develops them exclusively for the China market. The brand-new dream mid-level car is a car that is planned and developed with the goal of building the car that China customers really need. For the ninth-generation Accord, Guangqi Honda also conducted a detailed consumer survey in China, aiming to build the ninth-generation Accord in China into a leading new-generation vehicle in the world.

  Honda’s global R&D team visited China and found that China consumers have always pursued the aesthetic characteristics of "atmosphere and dynamic" for car modeling. Cars are not only vehicles, but also the best endorsement of personal style and temperament. The development of the ninth-generation Accord takes "advanced, atmospheric and full" as the key words, and adopts the front face shape full of tension and showing the atmosphere. The integrated waistline design is more visually impactful and shows extraordinary tolerance. More sporty rims and luxurious and dynamic built-in double exhaust pipes give people a brand-new visual shock, and the LED front and rear light groups adopted for the first time show their advanced and scientific sense. With its unique appearance of "China Aesthetics", the ninth-generation Accord hits people’s hearts, which perfectly fits China consumers’ expectation of high-class cars.

  At the same time, the survey found that the mainstream consumers in China’s mid-to-high-end car market are the enterprising elite, and they are elites in all fields of life. Compared with the past, they are more passionate and energetic, pay attention to the quality of life, and like to try and challenge new things. They believe in "the power of dreams", hope to constantly break through the limits of life with innovative thinking, and look forward to practicing their dreams with leading technology and creating their own era. On the basis of in-depth insight into consumer demand, Guangqi Honda further strengthens the sense of technology and luxury of the ninth-generation Accord, positioning itself as the "flagship of full-value evolution technology" and perfectly surpassing the expectations of the social elite for mid-to high-end cars.

  Because of this, the ninth-generation Accord not only embodies the essence of Honda FUNTEC technology, but also has the design of "China Yuanchuang" and the exclusive intelligent equipment of China. This is not only Honda’s first localized design of global strategic vehicles, but also enables the Accord brand to realize the "synchronization with the world" to "synchronization with the world", which reflects the importance of China market and Guangqi Honda’s sincerity to China consumers. It also opens a brand-new research and development model for middle and high-level joint venture vehicles, making the ninth-generation Accord surpass the meaning of "replacement" at the beginning of its birth and become a pilot work of comprehensive innovation.

  Help Guangqi Honda to return strongly and set off a new round of gorgeous development chapter.

  With the official listing of the ninth-generation Accord, after the brand-new and brand-new dream mid-level car Lingpai, Guangqi Honda made its debut in 2013 with three brand-new models, and Guangqi Honda, which celebrated its 15th anniversary, will open a new chapter of development. As the best endorsement of Guangqi Honda’s innovative spirit, the ninth-generation Accord will not only continue to write the legend of mid-to high-end auto market, but also inject vitality into Guangqi Honda’s strong return with its scientific and technological charm of full value evolution. At the same time that the ninth-generation Accord went on the market, Guangqi Honda has already laid out in advance in the fields of channels, production capacity and services, laying a solid foundation for the ninth-generation Accord to open the pilot road.

  In terms of channel construction, Guangqi Honda has started the construction of brand-new standards for national special sales service stores. In 1999, with the listing of the sixth-generation Accord, Guangqi Honda took the lead in creating a "four-in-one" sales and service model in the domestic automobile industry and creating a brand-new automobile service standard. In order to achieve higher customer satisfaction, Guangqi Honda launched a channel innovation plan this year, introducing brand-new store building standards and transforming the existing special sales service stores. With the six highlights of expressive appearance, theater exhibition hall, library-style lounge area, interactive experience digital exhibition hall, super garden landscape and green low-carbon environmental protection building as the standards, it is committed to building a new benchmark for automobile channels, comprehensively improving the hardware physique of special stores and leading the industry level again.

  In order to respond to the needs of the digital age, Guangqi Honda officially launched the "e-moving the future" project as early as 2012, and has completed the IT system planning in all areas of sales and services. At the level of special stores, it will comprehensively strengthen the interactive experience and digital marketing of customers, not only build a brand-new mobile office platform, but also get rid of the constraints of venue space and display the advantages and advanced technologies of products in an all-round way.

  At the same time, Guangqi Honda also launched a network revitalization plan this year, comprehensively improving the marketing capabilities of special stores and the service capabilities of the whole value chain, and creating service standards that once again lead the industry. In terms of after-sales service, Guangqi Honda won the runner-up in the China after-sales service satisfaction index of J. D. Power in 2013, which has been among the top three for five consecutive years since 2009, among which it won the first place three times and the second place twice, and its customer satisfaction score was the highest in CSI history several times. Outstanding after-sales service has provided important support for Guangqi Honda to win the trust of 3 million users, and it has become an important guarantee for the ninth-generation Accord owners to enjoy quality service. In terms of production capacity, Guangqi Honda started the construction of the third plant in May this year. After the completion, the total production capacity of Guangqi Honda will reach 720,000 units, laying a solid foundation for the intensive introduction of new products by Guangqi Honda in 2013.

  Yu Jun, executive deputy general manager of Guangqi Honda, said: The ninth-generation Accord has surpassed the traditional concept of replacement, is a master of Honda’s brand-new technology, and is also a super subversive of the middle and high-end auto market. The perfect presentation of the world’s leading innovative technology on the ninth-generation Accord makes the ninth-generation Accord continue to lead the same level in the China automobile market, and will become the superstar and power source of Guangqi Honda’s strong return. In the future, Guangqi Honda will continue to enrich its product range to meet the market demand, develop rapidly at a speed higher than the industry growth, and achieve greater breakthroughs.

As an important variety in the futures market, soda ash futures have attracted much attention for its characteristics and market prospects. Soda soda, whose chemical name is sodium carbonate, is widely used in glass manufacturing, detergent production, pulp and paper making and other industries. Therefore, the fluctuation of soda ash futures not only affects the cost control of related enterprises, but also has a far-reaching impact on the stability of the entire industrial chain.

First of all, the characteristics of soda ash futures are mainly reflected in the following aspects:

1. The relationship between supply and demand is complex: The production and consumption of soda ash are distributed in many countries and regions around the world, and the relationship between supply and demand is affected by many factors, including the price of raw materials, production technology and environmental protection policies. These factors make the price fluctuation of soda ash futures more frequent and larger.

2. The seasonal characteristics are obvious: The demand for soda ash shows obvious differences in different seasons. For example, due to the increase in detergent demand in summer, the consumption of soda ash will increase; In winter, the consumption of soda ash may decrease due to the decrease of demand in the construction industry. This seasonal feature makes the price trend of soda ash futures predictable.

3. The industrial chain has a wide influence: As a basic chemical raw material, the price fluctuation of soda ash will directly affect the cost of downstream products. For example, the glass manufacturing industry has a large demand for soda ash, and the rising price of soda ash will directly increase the cost of glass production, and then affect the market price of glass products.

Next, let’s look at the market prospect of soda ash futures:

1. The market demand continues to grow: With the development of global economy, especially the rise of emerging markets, the demand for soda ash will continue to grow. Especially in the context of increasingly strict environmental protection policies, the demand for soda ash as an environmentally friendly raw material will further increase.

2. Technological innovation promotes market development: With the continuous progress of production technology, the production efficiency and product quality of soda ash will be improved, which will help reduce production costs and improve market competitiveness. At the same time, the application of new technology will also promote the innovation and development of soda ash futures market.

3. The policy environment has a far-reaching impact: The adjustment of environmental protection and energy policies by governments of various countries will directly affect the production and consumption of soda ash. For example, the tightening of environmental protection policy may lead to the withdrawal of some highly polluting and inefficient soda production enterprises from the market, thus affecting the balance between supply and demand in the market.

In order to show the market prospect of soda ash futures more intuitively, the following is a simple table, which compares the influence of different factors on soda ash futures prices:

influencing factor Positive impact negative impact market demand Demand increases and prices rise. Demand decreases and prices fall. manufacturing technique Technological progress, cost reduction Backward technology and increased cost Environmental policy With the promotion of environmental protection policy, the demand increases. Limited by environmental protection policies, production is limited.

To sum up, the characteristics and market prospects of soda ash futures are influenced by many factors. When investors participate in soda ash futures trading, they need to pay close attention to market dynamics, rationally analyze the relationship between supply and demand, technological progress and changes in policy environment, so as to make wise investment decisions.

What is the charm of "Alita", which makes the card god forget it for 14 years?

Special feature of 1905 film network There is no doubt that Alita released this week is the most watched new film.

This film has been taken out from a very early age, and the Cameron effect is tightly tied. "It’s time to shoot", such a news has been delayed for ten years, and this one has been delayed for 14 years.

 

In 2005, there was news that Ka Shen was going to adapt Japanese cartoons. As a result, the procrastination card god naturally did not carry out the project quickly. Later, after a series of events such as changing directors and changing schedules, the film finally met with you.

 

Even though the director used Hollywood B-film director robert rodriguez, Ka Shen was still not idle, and all the publicity was done by himself. He repeatedly stressed that although he abdicated as a director, he still participated in it as a screenwriter and producer, not just in name only.

Cameron and robert rodriguez.

Even, the propaganda put Alita together to create the "A-word universe" of the card god, and can’t wait to announce to the audience that "the card god’s products must be fine."

 

What is this "card god work" like?

 

Rotten tomatoes in North America are divided, and the freshness of professionals is 59%, which is in sharp contrast with the audience’s preference of 94%. Although it has been loved by many audiences, compared with the previous "works of card gods", this film is much weaker in word of mouth.

The domestic reputation is OK, with Douban score of 7.6, Cat’s Eye score of 9.0 and Taobao Film score of 8.9.

 

Judging from the evaluation of various audiences, whether they like it or not, everyone talked about the special effects of this film. Indeed, the CG special effects of the whole work are the top in this industry, and there is no fault at all. If the audience who reject CG, they can choose to wash their eyes with this movie.

However, why did this movie make a group of people dislike it so much?

 

Perhaps the script of Alita has to carry a big pot. In the long 122 minutes, the script took more than an hour to lay out and show the world view of the whole story, and then it took 40 minutes to develop, but in the end it only took 10 minutes to end quickly.

The performance of special effects is emphasized too much, but the core story is weakened, which leads to the film being as cold as the robot in the film and losing its proper temperature.

 

But in fact, before talking about this film in detail, let’s talk about the original gunnm, and what magic it has made Cameron forget about it.

 

What’s so fascinating about the setting of the original gunnm?

 

Gunnm is a typical cartoon with eschatological theme, which tells the story of the wasteland world where robots and people combine, and it is also a work full of Cyberpunk style.

 

Before this, another cartoon with a similar theme has been published, which began to discuss the impact on future social morality and order after the rapid development of science and technology in modern times.

Ghost in the shell.

Back to reality, it was also the fastest period of Japan’s economic development, but it was also the early stage of the bubble economy about to burst. In those years, although Japan’s per capita GDP surpassed that of the United States, and even many people began to buy industries in the United States crazily, in fact, after signing the Plaza Accord, the yen depreciated for five years, which made many people full of fear.

 

As a result, a number of similar works emerged in Japan during that period, and gunnm was one of them.

Gunnm has a total of 9 episodes, with the theme of describing human nature. Compared with The Crushing of the Shell, which has already discussed the issues of soul and body in a deeper level, gunnm shows readers the world view from the beginning — —

 

In the 26th century, the world was a mixture of light and darkness, including the unequal relationship between the city of Salem in the sky and the town of scrap iron in the world.

 

Compared with previous films such as ghost in the shell, everyone is drawing a lot of pen and ink to speculate on the boundary between human and robot. But in gunnm, directness doesn’t exist.

As long as you have a human brain, it belongs to "people".

 

 

Of course, for any works with eschatological themes, the most difficult thing is to set the world outlook.

 

It didn’t take long for comics to be directly presented to two worlds that are not connected with each other. In fact, they directly presented classes to everyone.

In addition, there is a corresponding class in the scrap metal town. Makhakhe, Alita’s arch-rival, was born like the "Penguin character" in the movie, and had nothing to do with the excitement on the ground. In the cartoon, Alita finally asks Makhakhe,"Our bodies are all made by people. Why do you become a strange bug?"

 

Gunnm’s worldview inevitably reminds people of George Orwell’s 1984.

The binary opposition between the ruling class and the ruled class, which is the most typical in 1984, is perfectly presented in gunnm, even darker than the former. In "gunnm", the dystopian setting is even more cruel, and the residents of the scrap iron town are managed by an absolute high-pressure policy. In fact, this absolutely opposite description of the world has also influenced many subsequent works, such as space-opposing science fiction movies.

The original Yukio Kimura himself said, "In the period of creating sci-fi comics, it was George Orwell’s 1984, ridley scott’s blade runner and george miller’s Mad Max that influenced me."

 

In the setting, Alita is pregnant with "Mecha", which is also an ancient martial art of Mars. In fact, this Mecha technique originated from the martial arts on the earth, and the original author, Yukio Mucheng, specially incorporated many elements of China boxing. Because the Japanese had misunderstood China’s boxing at that time, the original work specially collected all kinds of fighting materials to show them better in the comics.

 

From comics to movies, where did you move?

 

In fact, the main story line of Alita is placed in the first four works of gunnm. However, Hollywood has never been so quiet about the reform, and other series of "gunnm" are mixed in the story, including the subsequent "last order".

 

However, in the movie, many different adaptations have been made.

 

The original cartoonist Yukio Kimura himself said, "The heroine of "gunnm" is Gary, and the movie uses the name Alita in the American version. In the original, Gary is a relatively introverted character, and Alita in the movie has a strong personality and often laughs."

The film shifted all kinds of perspectives to Alita, and even became more personal, so that Alita became a "guide" and took the audience to appreciate the world view of the world. After this adjustment, the director finally turned a dystopian story into a Hollywood-style personal heroism story.

 

The heroine Alita is relatively special. She was dropped from "Shalem". She has amnesia, but deep in her memory, she has her own fighting skills to kill the enemy. The story also slowly became "Alita’s search for herself".

In the movie, the relationship between the characters around Alita is subtracted.

 

First of all, it makes the relationship between Alita and medical ethics more concrete, giving up all the foreshadowing in the original work.

In the original work, medical ethics did not have a female assistant and wife, and even the name for Alita was actually the name of his dead cat. This change may be to increase the emotional expression of medical ethics regarding Alita as a daughter. But in the original book, medical ethics only treated Alita as a pet at first. Such changes have also made this branch line more direct, and there is no need to spend too much ink on it.

 

However, for the setting of her boyfriend Hugo, the film adaptation seems to be less convincing.

In the original book, there are actually two rules in the scrap iron city. Apart from the movie "People are not allowed to hold any guns", there is also a "Scrap iron city is not allowed to fly". This setting is the key to Hugo’s obsession with Salem — — His brother was shot dead for making a hot air balloon and trying to go to Salem.

 

In addition, the film still retains many comic details.

 

For example, at the beginning of the movie, when Alita woke up, the doctor handed her an orange, and she didn’t know what it was and took a bite. The details and emotions of these original works are displayed on the big screen, which not only has the "soul" of comics, but also has the uniqueness of movies.

Of course, the film still left a foreshadowing — — Dr Nova plays a very important role in gunnm. At the end of the film, it seems that he is set as the supreme leader of Salem. But in fact, he is another outstanding manifestation of rebellious spirit in the original work.

 

Cameron has left a big hole here. I don’t know how to reverse it in the future, but will there really be a chance to fill it? Even he himself said, "Look at the audience in China".

Beijing: Millions of primary and secondary school students will set up order maintenance posts in front of the school tomorrow.

  Beijing Morning News (Reporter Liu Jia) Tomorrow, millions of primary and middle school students in this city will usher in a new semester. Some schools beat us to it by holding the opening ceremony today. In the new semester, the city’s education pattern has been quietly fine-tuned, and "new schools" in some districts have emerged again.

  The new semester is approaching, and several "like mushrooms after rain" have sprung up on the education map of this city. The Beijing Morning Post reporter learned from the five districts of Dongcheng, Haidian, Shijingshan, Chaoyang and Shunyi that on September 1, there were six "new schools" respectively, including newly built schools or newly listed schools.

  In April, the "1+3" pilot project was added to the New Deal of China Merchants in this city, that is, from this year on, the students enrolled in the nearby public junior high schools in the sixth district of the city will receive the quantitative quota allocated for them by high-quality senior high schools after the end of the second school year, and continue to study for four years from grade three to grade three. The schools participating in the pilot include Tsinghua High School Attached to Tsinghua University, Peking University High School Attached to Beijing Normal University and other municipal-level co-ordination schools; It also includes ordinary middle schools in six districts of 16 cities, including Beijing No.57 Middle School and Beijing Experimental School, which have certain school-running characteristics and good school-running foundation. Students who enter this experiment will go straight to high school without taking the senior high school entrance examination.

  In September, the first batch of "1+3" experimental project freshmen will welcome their opening ceremony. The reporter learned from the jiang tai Campus of the Middle School affiliated to Tsinghua University that this year, the school plans to enroll 400 students, including 300 boarding students and 100 day students, but the final enrollment is 240.

  Primary and secondary school playgrounds are open.

  The timetable can be found online

  Beijing Morning News (Reporter Zhang Lu) In the future, citizens will no longer have to worry about having no place to exercise. Yesterday, the 16th district of this city announced the date and time for the sports facilities of primary and secondary schools to go to open directory project, so citizens can choose the school sports venues near their homes to exercise. The window of the capital opened the column "Inquiries about the opening of school sports facilities to the outside world" yesterday. The Beijing Morning Post reporter noted that some school venues receive activities organized by community organizations, and some suburban schools are open to the public free of charge during some winter and summer vacations.

  In order to give full play to the function of school sports venues and provide exercise venues for the surrounding residents, 16 districts announced the opening time, methods, projects and school addresses of school sports facilities in each district yesterday. The opening time and mode of each school are different. Take Dongcheng District as an example. Among the more than 50 primary and secondary schools open to the outside world, some only receive activities organized by community neighborhood committees, some only open in winter and summer vacations, and some only receive students from our school on weekends, but there are still a large number of school venues open to the public after 17 o’clock from Monday to Friday. The venues of most schools in Shijingshan are open on weekends and holidays, but you need to make an appointment in advance.

  In terms of open sports, most schools take track and field, basketball, table tennis, badminton, football, volleyball and fitness, and some also include roller skating, swimming and diabolo. In terms of opening prices, most districts are not clear about whether they are open for free.

  At the same time, some schools in the outer suburbs are clear and open for free in some time periods. For example, the stadium of Guangguang Central Primary School in Pinggu District takes the form of registration, self-provided equipment and free opening on weekends and holidays. In addition, venues such as Beiluyuan School and Zhoukoudian Middle School Stadium in Fangshan District are also free to open during the winter and summer vacations.

  Coping with the most blocked September

  ■ means of transportation

  Six roads for motor vehicles were completed and opened to traffic in September.

  Tomorrow will enter the most congested September. Zhou Tian, deputy director of the Traffic Commission’s Slow Congestion Work Office, said that September is the month with the greatest traffic pressure in the whole year. Combined with the traffic data over the years, it is predicted that there will be eight key days this year, namely September 1, 8, 9, 13, 14, 18, 29 and 30, and the traffic congestion index during peak hours will reach more than 8.

  Zhou Tian revealed that in view of the most blocked September, in addition to the increase of bus and subway capacity, six road projects are expected to be completed and opened to traffic in September this year, including Xixinglong Street, the western section of New Culture Street, Langxinzhuang Road, the west extension of Tianxiu Road, No.3 Road in Huaifang New Village and No.1 Road in Gucheng South.

  8,000 public rental cars have been added to bike zone 5.

  In addition, Zhou Tian revealed that in September, it will continue to increase the system construction of public bicycles. It is estimated that 8,000 public bicycles will be added in Haidian District, Fengtai District, Shijingshan District, Tongzhou District and Daxing District. At the same time, the equipment inspection of the site will be strengthened, the response speed of maintenance personnel will be improved, and faults will be repaired in time. "We will build car blocking piles on 300 roads in the city to provide a good traffic environment for pedestrians." Zhou Tian said.

  Subway Line 6 runs at 2: 30 in the morning and evening rush hours.

  Yesterday, the reporter learned from Beijing Metro that starting from September 1st, Metro Line 6 will use the newly compiled weekday train operation map to shorten the morning and evening peak departure interval, and passengers can wait for a train at the earliest of 2: 30. Beijing Metro said that after the implementation of the new operation map, two groups of trains were added to the morning rush hour of Line 6, reaching 49 groups, and the train interval was reduced from 3 minutes to 2 minutes and 53 seconds, increasing the capacity by 4.05%; There will be 53 trains in the evening rush hour, and the minimum departure interval will be reduced from 2 minutes and 45 seconds to 2 minutes and 30 seconds, increasing the capacity by 10%.

  According to the introduction of Beijing Metro, the subway passenger traffic has been running at a high level since this year. While improving the line capacity, the contradiction of some line capacity still exists. Take Line 6 as an example. During the morning rush hour, the passenger flow pressure in the eastern section of the line is relatively high. There are 9 stations from North Canal West Station, Materials College Station to Jintai Road, all of which are normal current-limiting stations, and the maximum full load rate reaches 119%. After the adjustment of the minimum train interval and traffic organization mode, it is expected that the maximum full load rate will be reduced to 115%. In the evening rush hour, the maximum full load rate of Line 6 will be reduced from 101% to about 91%, effectively alleviating the transfer pressure in hujialou station.

  ■ Traffic order

  Set up order maintenance posts in front of the school.

  Beijing Morning News (Reporter Huang Xiaoyu) The reporter learned from the Municipal Traffic Management Bureau yesterday that in view of the heavy traffic pressure in the city in September, the traffic control department took a number of measures to ease congestion and strengthen the maintenance and management of road traffic order around key areas in combination with holiday arrangements and the travel needs of citizens.

  The traffic control department has launched a high-level attendance plan, and the whole police are on the road and go all out to prepare for various responses. During the morning and evening rush hours, the patrol posts on the main roads of the Second, Third and Fourth Ring Roads and within the Fourth Ring Road will be arranged with two-wheeled motorcycles to the maximum extent to ensure that the police with sudden warning on the road will arrive at the scene quickly.

  It is understood that the traffic control department has deployed police forces to set up order maintenance posts in front of the campus to maintain order and guide parking after the school starts on September 1 and during the peak hours of going to and from school. In the near future, the traffic control department will also step up efforts to rectify illegal activities such as illegal parking of motor vehicles, illegal soliciting of passengers by disabled people, and disturbance of road vendors. The traffic control department reminded that parents who pick up and drop off students by car should stop and leave around the campus, and do not park illegally to avoid affecting the normal traffic of other vehicles and pedestrians.

Volkswagen Maiteng New Energy Vehicle Price

On December 18, this model was officially launched, with a price range of 186,900 yuan to 309,900 yuan, and a total of 4 power 10 models were launched. Among them, the GTE plug-in hybrid version was introduced into the Chinese market for the first time, undoubtedly providing consumers with more choices.

大众迈腾新能源

As a mid-term replacement, the power configuration of the new Maiteng is relatively stable. The fuel version 280TSI and 330TSI maintain the original performance, with a maximum horsepower of 150Ps and 186Ps respectively. The 380TSI is equipped with a 220Ps engine with a torque of up to 350Nm.

It is worth mentioning that the GTE plug-in hybrid model is equipped with a combination of a 1.4T engine and a motor, with a combined maximum horsepower of 211Ps and a torque of 400Nm.

It only takes 7.7 seconds to accelerate 100 kilometers, with a pure electric battery life of 56 kilometers, and a comprehensive fuel consumption of as low as 1.8L/km, demonstrating excellent performance and environmental advantages.

In terms of appearance design, the new Maiteng adopts a new design language, the front line is more dynamic, and the middle net and lower grille of the front part of the car integrate novel elements, making the overall shape much younger. Despite this, the professor said that some people may feel "face blind".

The tail markings and light sets have also been upgraded to enhance recognition.

In terms of interior, the Maiteng GTE model inherits the luxury of Volkswagen, equipped with a full LCD instrument panel and touch-sensitive audio control panel, which is full of technology. At the same time, the driving experience has also been improved, including a new steering wheel and a number of intelligent configurations, which enhance the practicality of the vehicle.

In comparison with the rival Honda Accord, the new Maiteng has shown a different competitive advantage from the Accord with its rigorous design and tradition, as well as its personalized positioning for different market needs.

Although Accord once led the market with the outstanding performance of the 1.5T engine, Maiteng has adopted mid-term modifications and the introduction of new energy models.

Further strengthening its market position, especially in cities with restricted purchases, Maiteng GTE will make up for its shortcomings in the new energy sector and enhance its competitiveness.

Overall, the new Maiteng has shown strong product strength with its innovative appearance, technological interior and targeted upgrades, which will make the competition between German and Japanese B-class cars even more intense. This model will undoubtedly bring consumers a new driving experience and value choices.

The big model faces four key defects. Can the "knowledge equation" lead to strong artificial intelligence?

The birth of artificial intelligence (AI) model makes 2023 an important year in human history-the first year of general artificial intelligence. This means that the fourth industrial revolution, represented by the intelligent revolution, has arrived, and mankind has stood on the threshold of the intelligent age.
The first three industrial revolutions experienced by mankind have made human civilization achieve a new leap, and also had a far-reaching impact on the world pattern. In the long run, artificial intelligence may surpass human beings in many aspects, but at present, general artificial intelligence still needs to go through many thresholds to truly realize strong artificial intelligence.
A few days ago, the Knowledge Computing Laboratory of China University of Science and Technology put forward a new knowledge model "knowledge equation", and based on this, established a new expert system. By combining with deep learning, it tried to break through the technical bottleneck of the existing general artificial intelligence.

Artificial intelligence (AI) has only been born for more than 60 years, but its development has experienced several ups and downs. In recent years, deep learning technology has brought a new revolution to AI, including AlphaGo and ChatGPT, which we are familiar with.
At present, AI technology has achieved remarkable results in many tasks, including face recognition, speech recognition, character recognition, etc., and has also delivered relatively satisfactory answers in the fields of machine translation, question and answer and medical diagnosis. It can be said that AI has entered a stage where it can be applied on a large scale.
However, when we try to push artificial intelligence forward, we will find that to overcome its existing defects, we still need to innovate and break through the technical model.
The current big model faces four key defects.
ChatGPT launched by OpenAI is an AI chat robot program, and it is also a tool for automatic content generation (AIGC) by artificial intelligence. As a dialogue system, ChatGPT has excellent versatility, whether it is talking about a variety of topics, solving math problems, providing gift selection suggestions and making itinerary plans, it can be handled calmly. Therefore, in a sense, ChatGPT has a wide range of application potential and flexibility, which can be said to be a general artificial intelligence (AGI) program.
Although the evaluation in some aspects (such as logic and semantic understanding) shows that ChatGPT is not more powerful than the existing best model in all fields, the existing best model may only be designed for specific tasks, while ChatGPT is a general model.
In fact, people realized the great potential of the big model many years ago, but its actual development speed is still much faster than expected. As soon as the ChatGPT big model came out, it soon attracted great attention at the application level. Half a year later, more than 100 large models emerged in China.
At present, the application of big model is mainly divided into three categories: Generative Artificial Intelligence (AIGC), assistant tools of big model and personal intelligent interaction. Among them, personal intelligent interaction is particularly worthy of attention. Any technology and product that can really promote interaction can generate great value. This kind of interaction includes not only "man-man" (through machines), but also "man-machine" and even "machine-machine". Artificial intelligence, including large models, is expected to make a subversive breakthrough in this regard.
(Source: vision china)
However, at present, the application of large models is not as smooth as expected. The fundamental reason is that although the big model is powerful, there are still some key defects in technology.
First of all, large models sometimes make factual mistakes, that is, reliability problems (commonly known as "hallucinations"). For example, it will mistake the author of the poem. In principle, the answer selection of large model is based on probability, so it is difficult to guarantee 100% accuracy. This problem exists in large models in many fields at present, and it is also one of the most important challenges faced by large models.
secondThe mathematical and logical reasoning ability of the large model still needs to be strengthened.Although GPT-4 performs well in some exams, when faced with some well-designed logical reasoning questions, the answers of the big model are almost the same as the random answers. Because in deep reasoning, even if the prediction accuracy of each step of the large model is as high as 95%, when the reasoning reaches 20 steps, the final accuracy will be 0.95 to the 20th power, that is, less than 36%, which is an unsatisfactory result.
thirdThe formal semantic understanding ability of the large model needs to be improved.Although the large-scale model can achieve semantic understanding to a certain extent, there is still much room for improvement in order to truly understand the meaning behind the language in terms of meaning and form.
finallyAs a black box model, the big model has some general weaknesses.For example, its interpretability and debugging ability are weak.
Leading to strong artificial intelligence may require another way.
The big model opens the window for the application of general artificial intelligence. But as mentioned above, some key defects in technology mean that there is still a long way to go between it and general strong artificial intelligence. To shorten this distance, there are at least two different paths worth exploring.
The first path is to continue along the existing development route of the big model. AI has only been born for more than 60 years, and GPT has only been training for five years. If the big model is allowed to develop for another 5, 50 and 500 years, what progress will it make? This is a question worth thinking about.
Along the existing technical route, the development of large-scale model will encounter certain challenges at two key points.
First, more parameters.With the increase of parameters, the ability of the large model will be improved. Moore’s law shows that the computing power doubles every 18 months to 24 months, while the parameters of large models are increasing at the rate of doubling in three or four months. Therefore, the computing power will soon fail to keep up with the development needs of the model. Moreover, although the parameter quantity increases exponentially, its effect only increases linearly.
Second, more data.The increase of high-quality training data will also improve the ability of large models. However, GPT-4 has used most of the high-quality text data that we can obtain at present. Therefore, the data available for large model training is about to reach the bottleneck.
Therefore, in order to solve these problems within the large model system, it is necessary to develop new subversive technologies to break through the bottlenecks encountered in structured information, declarative facts, long-chain reasoning, and deep semantic understanding.

Another path to general strong artificial intelligence is very different.
At present, AI is undergoing a paradigm shift from perceptual intelligence to cognitive intelligence. As we all know, human beings have two sets of reasoning systems, namely, the fast system of intuitive thinking and the slow system of rational thinking. Fast system is a low-level, fast, subconscious reasoning method that can draw conclusions immediately without thinking, just like people can find the location of the bathroom with their eyes closed at home; However, when we want to find a bathroom in a strange environment, we need to rely on the slow system for careful thinking. This reasoning is relatively slow, consumes more energy, but is more accurate.
At present, the large-scale model is more related to the reasoning at the level of fast system, and the reasoning ability of slow system is not good. Therefore, people will naturally think about whether these two systems can be combined.
In fact, the last wave of AI was driven by expert systems. Expert system is a kind of reasoning method similar to human slow system. It inputs expert knowledge into the machine in a symbolic way, and then through automatic reasoning, the machine can automatically answer questions like an expert.
Expert system and large model have their own advantages. The former performs better in accuracy, interpretability, logical reasoning ability and semantic understanding ability, while the latter has more advantages in universality, generalization, uncertain knowledge and learning ability. Therefore, the organic combination of expert system and large model can complement each other, which is a better path to general strong artificial intelligence.
Integrating two reasoning systems to explore future intelligence
Scientists in China have begun to explore the combination of expert system and large model. A new knowledge model is put forward by the Knowledge Computing Laboratory of China University of Science and Technology."knowledge equation"On this basis, a new expert system is established and integrated with deep learning.
In short, knowledge equation is divided into two levels: modeling and knowledge. On the modeling level, knowledge equation abstracts domain objects into three grammatical elements: individual, concept and operator, which can be transformed and integrated with each other. On the knowledge level, the knowledge equation unified all knowledge into a knowledge equation with the shape of "a=b". Based on the knowledge equation, we put forward the paradigm of intelligent information system, which is driven by new data and knowledge, and combines large model and reasoning engine.
With the rise of big language models such as ChatGPT, based on the original information system with database as the core, big models can mine effective information from dark databases (text, images, videos, etc.) and make reasoning and (auxiliary) decisions to some extent.
In fact, this is a paradigm revolution in information systems. In all data, dark data accounts for the vast majority. The traditional information system must use some means (including manual, natural language processing, computer vision technology, etc.) to convert "dark" data into "bright" data in the database. This conversion can only deal with a very small part of dark data because of engineering and cost problems. However, the large model can be directly output based on dark data, which has strong dark data processing ability.
The information system based on large model is similar to the fast system used by human beings for intuitive thinking, and can directly reason and make decisions based on big data to some extent. However, due to the current technical defects of the large model, it can not directly meet the application requirements in many application scenarios. The large model enhancement technology proposed by the Knowledge Computing Laboratory of the University of Science and Technology of China can build domain ontology and knowledge base, and on this basis, integrate large model and knowledge reasoning engine, develop an intelligent information system framework driven by knowledge and data, and combine fast thinking systems with slow thinking systems. Compared with the simple large model, the framework has the advantages of correctness, reliability, interpretability and debugging, and can significantly improve the application value of large models in all walks of life.
In addition to database and dark database, the system can also effectively use the information of knowledge base. Therefore, the framework is expected to lead another information system paradigm revolution after the big model, and will also become a new form of intelligent information system.
From the application point of view, the universal strong artificial intelligence is incomparable to the existing large model technology in both breadth and depth. In the long run, artificial intelligence may surpass human beings in many aspects, not only basic intelligence such as calculation, memory and storage, but also high-level intelligence such as decision-making, prediction and innovation. With the continuous development of computing-based large models and knowledge reasoning engines, AI will be closer to or even surpass human beings, which will greatly promote productivity.

These images of Han Dynasty pottery stoves unearthed in Yan ‘an, the source of exploration, were originally related to ascending to heaven and becoming immortal.

In recent decades, a large number of pottery stoves have been unearthed nationwide, mainly in Guanzhong, Luoyang, Jianghan, Shaanxi and Linyi areas. Since the end of 1990s, a large number of Han tombs have been found in Yan ‘an area of Shaanxi Province, and many pottery stoves have been unearthed, which can be divided into glazed argillaceous red pottery stoves and painted argillaceous gray pottery stoves according to their materials (Figure 1). These pottery stoves are unique in shape, exquisitely made and have regional characteristics. The author selects some representative unpublished pottery stoves from local museums to introduce them, and discusses their types, ages, crafts and symbolic meanings contained in their patterns.

As an appliance for people to make a fire and cook food, the stove appeared as early as the early Neolithic Age and was widely used in Yangshao culture period. In the Warring States period, stoves also evolved from primitive fire pits and movable pottery stoves into fixed pots and pans, which became an indispensable daily living facility for the ancients. As a funerary model, the pottery stove first appeared in the Qin tombs in the late Warring States period in Guanzhong area. In the Han Dynasty, when the concept of "death is like life" prevailed, the pottery stove was further made into a utensil, and it was buried with the pottery barn in a complete set, which became the core of the buried pottery in the tombs of the Han Dynasty and an important carrier of people’s ideas and spiritual world in the Han Dynasty.

Fig. 1 Schematic diagram of the distribution of pottery stoves unearthed in Yan ‘an area.

Glazed argillaceous red pottery stove

1. Carve the yellow glazed green painted pottery stove with double cranes.

Unearthed in Linzhen, Baota District, Yan ‘an City in 2005. Three-eyed horseshoe. Length 23, width 22.5 and height 22 cm. The fire holes on the stove surface are distributed in the shape of "pin", and a small kettle is placed on it, and the stove kettle is separated. Put a green glazed deep-bellied retort on the right kettle, and put a small pot of red glaze and green color on the other two kettles, with a small spoon of green glaze crank in the pot, and put a small pot of red glaze and green color between two fire holes in the front row. The tail of the stove is a green glaze bottle-shaped hollow chimney. The kitchen utensils and appliances on the kitchen surface can be moved. A rectangular floor-standing fire door is opened just below the front wall of the stove. Two rows of diamond-shaped palisades are carved above the fire door with sharp tools, and a crane standing opposite each other is carved on each side. The knife method is simple and sharp.

Regional characteristics and age of ceramic stoves in San ‘an.

From the above introduction and the information currently available, it can be seen that the pottery stoves unearthed in Yan ‘an area of northern Shaanxi mainly include glazed pottery and gray pottery, among which glazed pottery stoves account for a certain proportion, with red and yellow warm glazes as the main glaze colors, and green glazes are rare, and the rich multicolor glazes are a major feature, and even three-color glazes appear, which is rare in other areas. These glazed pottery stoves are relatively simple in shape, with horseshoe-shaped stoves as the bulk, and the three fire holes on the stove surface are mostly in the shape of "pin", and a few are side by side. There are two kinds of fire doors: floor type and hollow type, with hollow type as the main one. The stove and kettle are multi-split. All kinds of kitchenware models on the kitchen surface are rich in variety and complete in configuration, including retort, basin, plate, jar, bottle, ladle, spoon and ear cup, and most of them can be moved, which is a true portrayal of real life, which is rarely seen in other regions and presents distinctive local characteristics.

There are a large number of gray pottery stoves unearthed in Yan ‘an. Except for a few square stoves and irregular stoves, like glazed pottery stoves, their shapes are mainly horseshoe-shaped, but most of them are connected with stoves and kettles. Fire doors are mainly floor-mounted Developed painting is a remarkable feature of Yan ‘an Han Dynasty gray pottery stove, with bright colors and complicated patterns, especially the painting of animals and figures on the pottery stove, which has its own characteristics, while the practice of molding the pottery stove into a whole round carving animal is only seen in China.

The distinctive regional characteristics of the above pottery stoves should be related to the special geographical location of Yan’ an. Yan ‘an is located in the south of northern Shaanxi, bordering Hetao in the north and Guanzhong in the south. Since ancient times, it has been a place where the northern grassland culture and the farming culture of the Central Plains are integrated. By the Qin and Han Dynasties, Yan ‘an was a county jurisdiction and became a transitional zone connecting the northern frontier and the imperial ruling center. The combination of advanced production technology and ideas in the mainland with the original local cultural traditions has formed a unique cultural phenomenon here. These Han Dynasty pottery stoves unearthed in Yan ‘an area are unique in shape, novel in decoration and distinctive in regional characteristics, which should be the concrete embodiment of this cultural phenomenon.

Because this batch of pottery stoves were handed in or collected after being unearthed in people’s production activities, most of the tomb information is missing, so their age is mainly judged according to the shape, decorative characteristics and some of the same artifacts. Judging from the shape of the pottery stoves in Yan’ an area, horseshoe-shaped stoves are the main ones, and three fire holes are distributed in the shape of "pin" on the stove surface. This shape of pottery stoves was mainly popular in the early and middle Western Han Dynasty in Guanzhong area. In particular, the colorful painted pottery stoves with group crane patterns introduced above have the same length and width and a small aspect ratio, which are even consistent with those of the Qin Dynasty pottery stoves in Guanzhong area. The age may be as early as the end of Qin Dynasty and the beginning of Han Dynasty, and may enter the early Western Han Dynasty due to the lag of cultural communication. From the point of view of decoration, the proportion of glazed pottery in Yan ‘an area is high, while the popularity of glazed pottery in Guanzhong area is earlier than that in the middle of Western Han Dynasty, and because of the lag of cultural communication, the popularity of glazed pottery in Yan ‘an area has at least entered the middle and late Western Han Dynasty. In addition, various kitchenware models are popular on Yan ‘an glazed pottery stoves, and similar practices are mainly popular in Guanzhong area from the late Western Han Dynasty to the Xinmang period. The difference is that Guanzhong pottery stoves directly print kitchenware on the stoves instead of placing model kitchenware. This difference is caused by different regions, and their ages should be similar. From the perspective of the same artifacts, in Yan ‘an area, there are mainly artifacts with the basic combination of ding, pot-like bronze wares, warehouse and stove models, cans, bottles, lamps, fuming stoves and other daily necessities, but there are no common artifacts after the Eastern Han Dynasty, such as wells, toilets, buildings, figurines, pigsty and millstones. The main popular age of this combination should be from the middle and late Western Han Dynasty to the Xinmang period. As can be seen from the above analysis,Tao Zao in Yan ‘an area appeared in the early Western Han Dynasty, and was popular in the middle and late Western Han Dynasty. It may disappear around Xinmang at the latest.

Production, decoration technology and artistic features

(a) the production process

According to the author’s observation, Yan ‘an Han dynasty pottery stoves were made by using block molding, bonding, kneading, wheel making, knife cutting and other technologies. For this horseshoe-shaped, rectangular hollow three-dimensional stove and the Wolong-shaped pottery stove described above, because of its complex structure, it is impossible to form it at one time. Instead, it is necessary to use a special mold to make mud blanks of various parts of the pottery stove in blocks, and then combine and bond them. Some kitchen accessories are also molded, such as dragon-shaped chimneys, ear cups and small scoops. The kneading technique is applied to some small kitchen utensils on the stove, such as small plates, pots and crank spoons on glazed pottery stoves. And those larger pots, retort, cans and chimneys have obvious marks of wheel system, which should be made of wheel system. Knife-cutting technology is a major feature of the production of pottery figurines in the Han Dynasty in northern Shaanxi, and it is also reflected in the production of pottery stoves in this area. For example, the production of the kettle and crank spoon in the painted pottery stoves with crane patterns described above is a combination of kneading and knife-cutting techniques. First, the rough shape is kneaded, and then the shape is trimmed and shaped by knife cutting.

(2) Decoration technology

Yan ‘an Han Dynasty pottery stoves are rich in decorative techniques, including glazing, painting, carving, sculpture, stamping and so on. Especially in the decoration of glazed pottery stoves, advanced decoration techniques such as monochrome glaze, multi-color glaze, carved glaze filling and overlapping glaze painting are used, which are rich in color and strong in contrast, and the decoration effect is refreshing, making them a masterpiece of glazed pottery products in Han Dynasty. The glaze application technology of multi-color glaze is the biggest feature of glazed pottery production in Yan ‘an area, that is, two or more glaze colors are applied to a pottery at the same time, which represents the highest level of glaze application technology of glazed pottery in Han Dynasty. This decorative technique has also been fully used in the production of glazed pottery stoves. There are not only two-color glazes, but also three glaze colors of red, green and black applied to an object at the same time, which has become a veritable "three colors of Chinese". Carving and filling glaze refers to carving patterns first, and then filling them with glaze, which has a strong contrast and prominent theme, such as the crane pattern and geometric pattern decoration in the double crane pattern stove introduced above, which may be inspired by the bronze mosaic technology. Overlapping glaze painting refers to the decorative method of drawing various patterns and ornamentation on warm bottom glaze with green decorative glaze, such as red glaze and green double-que pattern stove, and double-que and grid pattern drawn with green glaze on sauce red bottom glaze, which has great color contrast and good decorative effect. Painting is the main decorative technique of Yan’ an Han dynasty gray pottery stoves. On the one hand, these paintings are exquisite in decoration and rich in content, including cloud patterns, animal patterns, geometric patterns and figure patterns. On the other hand, it is colorful and varied, including red, white, black, yellow, green and blue. Some directly paint patterns on the clay tires, such as the above-mentioned pottery stoves 1 and 2. Others apply white color all over the body first,Then paint on the white color, such as gray pottery stove 3, stove 5 to stove 7, whose exquisite richness is rare in other areas.

(3) Artistic features

The combination of realism and virtuality is one of the artistic features of Yan ‘an Han Dynasty pottery stoves. Most of the glazed pottery stoves here are equipped with a complete set of kitchen utensils, such as kettle, retort, basin, jar, spoon and ear cup, which can reach as many as ten pieces at most, and the richness is beyond imagination. These utensils, regardless of their size, are accurate in shape and exquisite in manufacture. They are completely true imitations of cookers and kitchenware in real life, allowing us to see the configuration and combination of Han kitchenware, and the application of multicolor glaze decoration makes them a rare ancient miniature art. While being realistic, depicting the images of cranes and Quelou on both sides of the stove door should not be a simple description of the real world, but it has special ideological significance as the virtual practice of shaping the pottery stove chimney into a dragon’s head.

The coexistence of roughness and delicacy is another artistic feature of Yan ‘an Han Dynasty pottery stove. Using a knife instead of a pen, the grid pattern, diamond pattern, triangle pattern and crane pattern are carved on the wall of the glazed pottery stove. The knife method is vigorous and sharp, and the carved cranes have different shapes, or they are screaming or flapping their wings, and the picture is concise and powerful, which is extremely infectious. On the other hand, the clouds, figures and cranes on the painted pottery stove have smooth lines, delicate descriptions and vivid images.

Imagination and exaggeration are another artistic feature of Yan ‘an Han Dynasty pottery stoves. For example, the painted group of crane-patterned pottery stoves painted 12 cranes with different shapes and sizes on the narrow kitchen wall are full of interest and imagination. The description of the shape of the crane is bold and exaggerated, focusing on the slender and curved neck of the crane, which provides important information for us to study the painting level and skills of the Han Dynasty. The Wolong-shaped painted pottery stove introduced in the above article is even more imaginative in shaping a daily appliance into a round carved beast and applying exquisite painting, which is amazing.

The Meaning of Double Que Pattern and Crane Pattern on Five Pottery Stove

A pair of que Lou patterns are often carved, painted or embossed on both sides of the fire doors of glazed pottery stoves and gray pottery stoves unearthed in Yan ‘an, which is very rare in other areas. Quelou is a high-rise building located on both sides of the gate of an important building in ancient China. It is a sign of the gate. It should imply some special symbolic significance to depict it on both sides of the fire gate of the pottery stove. The Han Dynasty portrait bricks unearthed in Henan and the portrait sarcophagus found in Sichuan and Chongqing often show the double que pattern, and most of them coexist with the auspicious animals such as cranes, phoenixes and four gods, the sun, the moon, Fuxi, Nuwa and the Queen Mother of the West, and their images are similar to the double que on Yan ‘an pottery stoves. Some scholars believe that these double-que patterns are the "Tianmen" symbols leading to the fairy palace and the only way for the tomb owner to ascend to heaven and become immortal. The double-que pattern on the right wall of No.3 sarcophagus unearthed from Hanya Tomb in Guitou, Shandong Province, Jianyang County, Sichuan Province provides an important basis for this speculation. A single-eave double-que door is carved on the sarcophagus, and there is a person standing under the door. The word "Tianmen" is listed above the lintel, and the door with double-que is clearly called Tianmen. In the same way, the double que and rectangular fire gate on both sides of the fire gate of the pottery stove in Yan ‘an Han Dynasty and the geometric patterns above them together constitute the image of "Tianmen", which becomes the entrance for the tomb owner to ascend to heaven and become immortal. The soul of the tomb owner enters through the fire gate depicting the que building and turns into curled smoke rising from the chimney with the dragon head and flying to the fairy palace.

Crane pattern is also a more common image on Yan ‘an pottery stove, which is located in the same position as Shuangque pattern or on the side wall of the stove. In China’s Taoist thought, cranes are sacred objects in the celestial world, and immortals travel in the sky with cranes. Legend of the Immortals says, "Wang Ziqiao, Prince Jin Ye of Zhou Lingwang, a good blowing sheng, worked as Fengming, and traveled between Ilo, where Taoist Fuqiu was connected to Songshan. More than ten years later, I came to the mountain and told Huan Liang: Tell my family, and wait for the solution of Gou’s hill on July 7. If you take a white crane to the top of the mountain, you can’t see it. When you raise your hand, you will leave. " This record shows that the image of a crane as a fairy riding a sacred object appeared in the Han Dynasty. In the picture of immortalization in the Han Dynasty, tomb owners often use supernatural objects to ascend. In addition to the common dragon carts, fish carts and deer carts, cranes are also important carriers of immortalization. Found in the M1 mural of the mural tomb of the Eastern Han Dynasty near Yangqiao, Jingbian County, northern Shaanxi Province, there is an image of immortals soaring by cranes (Figure 15); In addition, the mural tomb M1 of Han Dynasty in Haotan, Dingbian County, northern Shaanxi Province is also painted with an image of a pair of immortals driving cranes to escort the tomb owner to Tianmen. It is the dream of the Han people to fly to immortality after death. The contents of the murals in the above two Han tombs are the same. The method of depicting the crane pattern on the pottery stove reflects the tomb owner’s desire to fly the crane to immortality from another aspect.

Fig.15 A painting by a fairy in Hebi, M1 of the Eastern Han Tomb beside Yangqiao, Jingbian County, Shaanxi Province.

The practice of decorating que Lou, crane and dragon-headed chimney on pottery stoves in Yan ‘an area reflects the good wish of Han people to ascend to heaven after death, and is the embodiment of Taoist immortal thought in local funeral customs. In addition, Quelou, crane design and dragon-headed chimney, three decorative themes closely related to the idea of immortalization, appeared on the pottery stove at the same time, but rarely appeared on other types of funerary objects such as pottery warehouses and bottles. This difference reflects the particularity of the pottery stove in the system of funerary objects in this area, and it is likely to be an important carrier of the idea of immortalization, which is not seen in other areas.
