Answer:
China has a vast territory, and the huge environmental differences caused by the geographical span of latitude and longitude give birth to the national folk customs with their own characteristics and unique style. In the diversification of customs, the differences in norms of behavior caused by the different natural conditions are called "wind". The difference between the rules of behavior caused by social and cultural differences is called "vulgarity". During the five thousand years of development in the land of China, the influence of natural, economic, geographical, historical and other factors has brought up the strange cultural phenomenon of "hundreds of miles of different winds, thousands of miles of different customs", and also brought up the colorful Chinese national culture. The differences in customs are reflected in various aspects such as clothing, food, housing and transportation, as well as the different expressions and meanings of festivals, such as the Spring Festival celebrated by the Han, Manchu and Korean peoples, the Tibetan New Year, and the Water-splashing Festival, a grand festival of the Dai ethnic group, which means everything is more meaningful... And so on. Generally speaking, in the melting pot of the Chinese nation, different national cultures show different national customs. These national customs are not only unique cultural symbols of a nation, but also an inseparable part of the culture of the Chinese nation. Together, they make this ancient civilization continue brilliantly.
