Lizhuang Ancient Town is located on the south bank of the Yangtze River in the eastern suburbs of Yibin City, Sichuan Province. It has a history of building a town in 1460 years. It is a thousand-year old town on the edge of the Yangtze River. It is known as the first ancient town of the Yangtze River. Those who have seen "The Besieged City" are sure to remember the story of the other party's Hongyan and Li Meiting and their trip to San Francisco University. In Li Zhuang, you will find that there are many similarities between real history and novels. The difference is that Li Ziz, Liang Sicheng, Lin Huiyin, Fu Sinian and Tong Dizhou, who live in Lizhuang, are academia. During the Anti-Japanese War, Shanghais National Tongji University and other institutions have moved five times, but they are still threatened by Japanese bombing and need to move to the southern part of Sichuan for the sixth time. At that time, some places had accepted the evacuated population and were overcrowded; many places were self-sufficient. In such an emergency, Li Zhuang resolutely issued a sixteen-character message entitled "Welcome to Daqianchuan and Lizhuang, All Needs, Local Supply". Since then, Li Zhuang has become one of the cultural centers of the rear of the Anti-Japanese War. With a riverside town of 3,000 people, it has accepted more than 10,000 cultural people borrowed from other provinces. Liang Sichengs "Chinese Architecture History" was born in Lizhuang. Therefore, it is no exaggeration to say that Li Zhuang is a "conservation of the national spirit and a refraction point of traditional culture."
