Shortly thereafter, the General Political Department entrusted the Military and Political University (now renamed the National Defense University) to hold a Marxist-Leninist "six books" reading class, and Ai Weiren was ordered to lead the propaganda directors of all military-level units in the whole region to study the Marxist-Leninist "six books" at the Platon Military and Political University in Beijing. In Class A, Ai Weiren mainly studied "Communist Manifesto" and "Criticism of the Gotha Program", "Materialism and Empirical Criticism". In addition, three books, "Anti-Dühring", "The State and the Revolution", and "On the French Civil War", are for class B courses. The cadets of the Chengdu Military Region were organized into a district team with the three units of the Shenyang Military Region and the Jinan Military Region; in the course of studying and studying, they became acquainted with several new comrades-in-arms, among whom they had more contacts, including Li Caixiang, deputy director of the Propaganda Department of the Shenyang Military Region, and Zhou Keyu, deputy director of the Propaganda Department of the Jinan Military Region. The trainees were very satisfied with the methods of carefully preparing lessons for the faculty of the Military and Political University, such as reading and hinting at key points. Aveyn deeply felt that this one-hundred-day study was another infrastructure construction after the study of philosophy in 1955, especially after reading the original works and gaining more from lenin's "Materialist Empiricism", which was really another more formal theoretical study.
After returning to the military region, after Ai Weiren reported the study of reading to the head of the Political Department, the leaders attached great importance to it and held the first reading class for cadres at and above the division level in the summer of 1971. Nearly 200 cadres at and above the division level of the military region were also cadres at and above the division level of the air force, navy, railway corps, and academies directly under the Central Military Commission stationed in the theater. Because business was depressed and idle for a long time during the "Cultural Revolution", the Chengdu Military Region held a reading class here that was very popular with hotels. They can have some income, some popularity, and even the business is not deserted. Ai Weiren served as the director of the reading class office, and in addition to giving some lectures, he mainly did teaching organization leadership work, life support work and safety protection work. The enthusiasm of the cadres who participated in the study class was very high; they conscientiously read books, criticized and rectified the work style in connection with Chen, and had a lively discussion, thus promoting the understanding and understanding of the basic marxist theories of Marxism, such as dialectical materialism and historical materialism. But it did not go beyond the historical limitations of affirming the "Cultural Revolution" and the so-called "theory of the continuation of the revolution of the proletariat".
Near the end of the study class, the Sichuan Hotel in Beijing was ordered to close on the grounds that the Sichuan Hotel was an intelligence agency set up by Li Jingquan at the side of the central government, and more than 20 of the hotel's cooks were expelled and sent back to the Jinniuba Hotel in Sichuan. It is said that during the meeting of the Central Committee before the "Cultural Revolution," some central leaders from Sichuan, such as Zhu De, Chen Yi, Liu Bocheng, Deng Xiaoping, Nie Rongzhen, Guo Moruo, Luo Ruiqing, and others, mobilized Li Jingquan, secretary of the Sichuan Provincial CPC Committee: "Political Commissar Li (a habitual name inside and outside the party), you should open an authentic Sichuan cuisine hotel in Beijing, we all want to eat authentic Sichuan cuisine, and we will never lose money when we open a shop in Beijing. "As a result, Sichuan Province has selected some well-known and excellent chefs with unique expertise to work in Beijing, and the Sichuan Hotel has been very prosperous after opening, and the customers are full of doors, of course, the central leaders of Sichuan and their families, relatives and friends are also regular customers on holidays." During the Cultural Revolution, the Public Prosecutor's Office Law was smashed, and what kind of shops were smashed, and the Sichuan Hotel was also smashed. Ai Weiren's reading office, after the completion of the students, engaged in summary and finishing work, some comrades are not enough gourmets, but they are a "glutton", they encourage Ai Weiren, the idea of let the chefs who returned from Beijing show their hands, everyone is also good to see. Therefore, at the farewell tea party after graduating from the reading class, Ai Weiren proposed that "please invite our hotel and the chefs who returned from Beijing to jointly present the performance, each chef makes a special dish, and the leaders and main staff of our hotel and the comrades and chefs in the reading class office have a meal together." Avijin also stipulated that instead of purchasing new things, he would use existing things to do. The comrades were happy, so were the chefs, and they warmly applauded and waited for the masters' high-level Sichuan cuisine performance at lunch the next day!
During the meal, while the chef is served, the chef introduces the method and characteristics of the dish. Everyone knows that Sichuan cuisine is fragrant, hemp, spicy taste is complete, the cultural heritage contained is very deep, the taste of the dish is very mellow, but mostly ordinary raw materials, Ai Weiren can remember the dish has several dishes: "baby chicken scoop white", this dish is the chicken with a knife back smashed, into the casserole slow simmer, until boiled into soup, a small amount of bone skin fished out, add fresh scoop white, stewed and cooked, the characteristics are to eat chicken without seeing chicken, baby chicken scoop white, not fat and not greasy, comprehensive nutrition. There is another dish called "June Snow", completely with egg white, salt, monosodium glutamate, a small amount of green onion white, with cooking bamboo dipped in egg white, scattered into the oil pot, that is, out of the pot, eat tender and delicious, unique flavor. Although Ai Weiren has eaten "June Snow" many times since then, he has not been as delicious as that time. The third dish is "Green Dragon Crossing the Sea", the fresh fish meat is smashed with the back of the knife, into the flavor, add egg whites and mixed into the fresh green onion leaves, the broth is boiled, into the pot, although this dish has a soup, it is a dish, the taste is fresh and tender, and it is unforgettable. There is also "King Farewell" (braised dough fish, baby chicken), "two-color, salty and sweet hibiscus cake", which is also a very delicious snack. He recalled that since the liberation of the great southwest, he has spent more than 23 years in Sichuan, which is a "peak meal" of Sichuan cuisine, mainly the chef is smart!
