Ancient sculpture belongs to non-historical and cultural heritage.

Intangible cultural heritage refers to various forms of traditional cultural expressions that exist in intangible forms and are closely related to people's lives and passed down from generation to generation. Intangible cultural heritage is a people-oriented living cultural heritage, which emphasizes people-centered skills, experience and spirit and is characterized by living changes.

In the practical work of intangible cultural heritage, the criteria for identifying intangible cultural heritage are father and son (family), master and apprentice, or school inheritance for more than three generations, and the inheritance time is more than 100 years, which requires a clear pedigree.
