What is the significance of China's traditional festivals to declare the world intangible cultural heritage?

In essence, intangible cultural heritage is a part of our national knowledge system and a very important and precious wealth. It condenses our historical memory. It is not only a record of yesterday's history and life, but also the reality of our life today and a very important foundation for future cultural development. Declaring intangible cultural heritage for traditional festivals in China can awaken our national memory and prevent us from losing ourselves in culture. Therefore, UNESCO put forward the idea of "protecting cultural diversity" for intangible cultural heritage in the Convention. Because human beings are colorful and every nation has its own culture, if we don't protect the intangible cultural heritage, our nation will be "melted away" and the essence of our nation will be lost. Therefore, in this sense, it is of great significance to declare and protect the intangible cultural heritage.
