Reasons for the formation of cultural heritage Heritage is an ancient word. Its original concept is the property left by ancestors. In this traditional view of heritage, heritage is only private material wealth. Since the middle of19th century, the connotation of heritage has changed quietly. Some people began to regard the public property with important historical and cultural value left by their ancestors as heritage. This is another sense of inheritance, that is, cultural inheritance. It is a public and spiritual wealth that needs to be shared by people and passed down from generation to generation. The emergence of this brand-new concept of heritage is due to the transformation of the whole human civilization. Human civilization has experienced two "changes" from ancient times to the present. Once, it changed from fishing and hunting civilization to farming civilization. In China, it was the Hemudu cultural period almost seven thousand years ago. At that time, human beings could not know how to protect the heritage, so the fishing and hunting civilization disappeared. Once again, it is nearly a century-the transformation from farming civilization to modern industrial civilization. In the transition period of civilization, the replacement of old and new things is very ruthless. And people can't see the intrinsic cultural and spiritual values of those things that are about to die. That's when the legacy died. Therefore, whoever can realize the value of the heritage earlier can keep the precious heritage. Charming and heavy Paris and Rome have been preserved by forward-looking eyes. Hugo, a French writer, first and most vividly expressed the new concept of heritage. In his famous "Declaring War on the Destroyer of Cultural Relics", he used angry language to reprimand those who wantonly destroyed the history of French cities at that time, and proudly defended the historical civilization of France. There is such a passage in the article-he said that he would "make laws for places of interest." Legislation for art, for the nationality of France, for nostalgia, for cathedrals, for the greatest works of human wisdom, for the collective achievements of our ancestors, for what is irretrievable after being destroyed, and for what is most sacred outside the future of a country ... "This passage was written in 1832. France is in the early stage of industrialization. His cultural sensitivity and sense of responsibility surprised us and impressed us deeply. This prescient and advanced article in the process of human civilization makes the new concept of heritage so clear. Historically, the new concept of heritage was always stubbornly expressed by some people of insight at first. Because of their indomitable efforts, these people gradually gained wide recognition, and then formed laws and regulations on heritage protection. The first French historical architecture law was formulated by the writer Merrimi. At the beginning of the 20th century, Britain, Italy, France, Japan, South Korea and other countries successively had some different types of heritage protection laws. Material and cultural heritage is visible, tangible, static and three-dimensional. For example, cultural relics, classic ancient books, great cultural sites, important historical buildings and so on. The scope of intangible cultural heritage is much wider, but it is often intangible and intangible. This includes folk customs, folk literature, folk art, folk skills and so on. Because intangible culture is mostly created and recognized by ordinary people, it has always been regarded as the bottom culture and has not been taken seriously. But it is a life culture that nurtures us, and everyone grows up in this common culture. Therefore, it directly expresses the individual characteristics of each nation, as well as their own sense of identity, affinity and cohesion. For example, the national temperament of China people is not reflected in the Summer Palace and the Forbidden City, but deeply and vividly reflected in the folk customs of the Spring Festival. Therefore, intangible cultural heritage can best reflect the essence of each nation and the diversity of human culture.
