Abstract: In ancient China, the interaction, communication, and integration among various ethnic groups formed a complex and lengthy historical process. During this process, some ethnic groups gradually integrated with other ethnic groups, ultimately dissolving in the long river of history without leaving clear records. As a "process type" in the history of Chinese ethnic groups, the dissolution of ancient ethnic groups actually promoted the commonality and consistency between different ethnic groups. The historical truth of this ethnic integration is a key factor for many modern ethnic groups to form and maintain their unique identities. While laying a solid material foundation for the formation and development of the Chinese nation, the contemporary value urgently needs to be deeply explored and understood.

Key words: Chinese People, national melting, communication and blending
