Immigrant culture: In the late Yuan and early Ming and late Ming and early Qing dynasties, there were frequent wars in Sichuan and Hubei, and there were two large-scale "Huguang filling Sichuan" in history. Today, the world-famous Three Gorges Project has turned Wushan into a large immigration county. After 10 years of war, 100,000 immigrants were relocated, forming a touching Three Gorges immigrant spirit.
