Significance of Eight Rites and Four Instruments:

Etiquette is established in people's life and social communication. People can correctly grasp the scale of interpersonal communication with the outside world and handle the relationship between good people reasonably according to various etiquette norms.

Without these etiquette norms, people will often feel at a loss in communication, and even be rude to others and make jokes. Therefore, if you are familiar with and master etiquette, you can learn by analogy and treat people just right.
