The combination of ceremony and music means that ceremony and music complement each other and are inseparable. Rite and music have the same root. In the eyes of Confucianism, ceremony is the criterion to maintain the universal order and social order of heaven and earth. Music is to reconcile the relationship between various grades and categories. Rites and music and shooting imperial books constitute the "six arts", which is the aristocratic education system in China Zhou Dynasty. Rites refer to moral education, in which pleasure is internal, shooting is archery, riding is driving, books are all kinds of historical and cultural knowledge, and numbers are mathematics.
