What is the difference between "intangible culture" and "intangible cultural heritage"

Hello! "Intangible culture" and "intangible cultural heritage" are different. Adding the word "heritage" means that this culture can't continue. Intangible culture covers a wide range, such as national literature and art undertakings, novels, cross talk, dough figurines, clay figurines and sugar blowers, but you can't say that they are all intangible cultural heritage. However, the culture of Shanxi merchants, Hemudu culture and Maya culture in a specific era are listed as intangible cultural heritage because they can't be copied now. Thanks for reading!
