The Song, Liao, Xixia, and Jin periods were an era of multi-ethnic strife and integration. All aspects of their social life show the richness and variety of customs of various ethnic groups, and there is me among you, and you among me. The Song, Liao, Xia and Jin dynasties were another period of great national integration in the history of our country. At that time, the Khitan, Dangxiang, Jurchen and Han people had long-term exchanges, exchanges and blends, and gradually accepted the traditional material culture and spiritual culture of the Han people. In other words, the historical Liao, Xia, and Jin cultures are not equal to Khitan culture, Dangxiang culture, and Jurchen culture. Without ethnic exchanges, exchanges and integration, there would be no establishment of Xixia and development of Xixia culture.
