The Confucian Confucian "ritual, music, shooting, imperialism, calligraphy, and mathematics" are collectively called the "Six Arts".

Etiquette mainly refers to moral education. "If you don't learn etiquette, you can't stand up." If you don't learn etiquette, you can't stand up and you can't be a human being.

Happiness does not only refer to aesthetic education; etiquette is external, and happiness is internal. Music makes everyone love each other, ritual makes everyone respect each other; music makes everyone the same, and ritual makes everyone different. This is clearly stated in the "Book of Rites and Music".

Shooting, archery;

Yu, driving; together they are sports and labor;

Books, various historical and cultural knowledge;

Numbers, mathematics.

In today’s terms, it generally means the comprehensive development of morality, intelligence, body, beauty and labor.
