Classification:

In different countries, the items listed in intangible cultural heritage are not exactly the same, because each country's nationality, history, culture and even national conditions are different. Therefore, the specific classification of intangible cultural heritage in different countries is not completely consistent.

However, the classification of intangible cultural heritage in the Convention for the Protection of Intangible Cultural Heritage issued by UNESCO after synthesizing the situation of intangible cultural heritage in various countries almost covers the basic situation of all countries in the world, and the classification of intangible cultural heritage put forward by Chinese scholars is almost based on the system established by this convention.
