Industrialization and urbanization have shaped the direction of population movements, which has made a huge difference in the nature of rural society in Eastern and Western China. Under the background of industrialization and a large influx of population, villages in the eastern region have gradually become industrial villages with mixed residents, and "Quasi-acquaintance Society" has become a new form of social structure in industrial villages. The existing concept in the academic world, "Baseless Society of Acquaintance " reveals a new form of social structure of agricultural villages in the Midwest, as the outflow of population, and the "Quasi-acquaintance Society" corresponds to it, forming a complementary interpretation of the social nature of Chinese villages in transition . In the industrial villages in the eastern region, people's sense of "familiarity" began to build up through primitive and constructive social relationships, but eventually formed a group-like structure and a "familiar but not close" relationship atmosphere. The formation of Quasi-acquaintance Society depends on people in a mobile society, through the "segmentation" and "clustering" strategies, to achieve the maintenance of livelihoods on the premise of ensuring the safety of survival. Regional differences in life also make it difficult to achieve integration between groups in a short time.
