Zhou Li Bao Jian said: "Cultivating the sons of the nation by Tao is the six arts of teaching: one is five rites, the other is six music, the third is five shots, the fourth is five orders, the fifth is six books, and the sixth is nine numbers." These "six arts" are the six basic abilities that China ancient Confucianism required students to master: courtesy, music, shooting, imperial command, calligraphy and number.
Rite: Etiquette (that is, moral education today)
Music shooting: archery skills (physical exercise, character training)
Yu: the technical book of driving a carriage: calligraphy (that is, modern literature)
Number: algorithm (that is, modern mathematics)
