What are the meanings of the six ancient arts "Li, Yue, Shooting, Imperial, Writing and Numbering"?

Schools in the Western Zhou Dynasty implemented the "six arts" education, which means etiquette (morality conforms to etiquette norms), music (music and dance in various ceremonies), shooting (archery), driving (driving), writing (writing) and divination (divination). Among them, the ceremony and music that promote the concept of hierarchy are the core, books and numbers are the foundation, and skills such as shooting and bending are also highly valued, and their achievements can be used as the basis for awards. Teachers are often served by officials. For example, court musicians teach music and dance, and teachers (officers) teach shooting and defense, hence the name "division".
