As an entertainment tool, it can not only entertain itself, but also entertain people; As an educational tool, it contains many aspects, such as clan history, productive labor, fighting skills, ethics, physical fitness and even sexual knowledge, which were once the contents of dance education. However, in the final analysis, it is an aesthetic activity. While exerting various functions, it can't be without aesthetic function, which can make people (including dancers themselves) enjoy pleasure and beauty.
Second, the court music and dance
Elegant music dance simply emphasizes the combination of music and ceremony, and is closely linked with political concepts and laws expressing social ethics, thus becoming an important ruling tool and being promoted to a sacred and inviolable height.
