Professor Wang Jie and his research team put forward the concept of local aesthetic experience in the process of research. The concept is used to summarize and refer to the existing way and existing form of non-westem mainstream culture in aesthetic dimension under global context. Local aesthetic experience converges many important problems in the research on aesthetic anthropology展开更多
