During the Yuan and Ming Dynasties, the economic and cultural exchanges between Han and Dai became closer, especially a large number of Han people moved to the frontier. The advanced production technology and cultural science in the mainland were widely spread in the Dai areas, which quickly promoted the social and economic development of the Dai people.
In order to defend the territory of the motherland, at the end of 19 and the beginning of the 20th century, the Dai people waged many armed struggles with the Han nationality, Jingpo nationality, Wa nationality and other nationalities, and opposed the aggression of British and French imperialism.
During the War of Resistance against Japanese Aggression period, the Dai people, together with the people of the whole country, participated in the armed struggle against Japanese fascism and made contributions to defending the sacred territory of the motherland's frontier.
