Mainland has been characterized by the rapid development of industrialization and urbanization during the past 30 years, which brought a broad range of population movements and in turn led to the loosening of the social integration and the rapid changes of traditional culture. Population movements put urban, environment, culture and even diseases in motion, and brought out a series of new phenomena and new problems, basing on which the applied anthropology developed rapidly and diversely in mainland. Although the name, applied anthropology, covered different areas of research, but there was still one core issue behind diverse academic focuses, which could be picked out as flows in the process of social transformation.
