What does non-legacy mean?

Intangible cultural heritage refers to the cultural heritage that does not exist in material form, but is passed down and expressed through human oral traditions, performing arts, social practice, festivals, related physical places and cultural landscapes.

These cultural elements are the crystallization of human wisdom and have important historical, cultural, social, ethnic, artistic and scientific values. They are passed down and spread through intergenerational inheritance and social practice, which embodies the richness of human diversity and creativity. Intangible cultural heritage has become an important part of world cultural heritage protection.
