China has always been known as the "state of etiquette" in the world.The so-called etiquette refers to the social rules and moral norms that people follow in various activities such as life, production, and social communication.These rules and regulations require a certain etiquette and formality to express.Over the years, these etiquette norms have spread day by day and gradually become social customs that people generally recognize and follow, also known as etiquette and customs.For thousands of years, with the development of society, the Chinese nation has produced, developed, evolved, and changed various rituals and customs, and gradually formed a set of cultural patterns that have penetrated into all social strata and aspects.Understanding ancient customs is not only helpful for the study of ancient social conditions, but also has practical significance for changing customs and building China's contemporary material and spiritual civilization.
