2. Confucius advocated and taught the six Confucian arts, which was originally an elite education method for the upper class in the Zhou Dynasty to educate future generations and cultivate martial arts. It was monopolized by the aristocratic class in the Zhou Dynasty and studied in the government. Shooting and bending were actually the military combat skills of the Zhou Dynasty, and the aristocratic children of the Zhou Dynasty had to master fitness skills. Therefore, if the nobles of the Zhou Dynasty wanted to keep fit, they preferred shooting and bending, and also participated in the collective hunting activities organized by the Zhou royal family every year.

3. Actually, learning music and rites is also a disguised form of fitness. Rites and music in the Zhou Dynasty were very particular about ceremonies, which required repeated practice and mastery of various standardized ritual and music movements. Every movement can't be wrong, and the effect is similar to that of modern broadcast gymnastics.
