There is an old saying in China that "a gentleman never leaves his body for no reason", and Confucius said that "a gentleman is like jade". The purpose of wearing jade is to always remind yourself that moral cultivation and character should be like jade. Confucianism believes that a gentleman should be obedient to the outside and tough to the inside; Be lenient with others and strict with yourself; Guanghua is reserved and unobtrusive. The quality of jade is closest to that of a gentleman, so China's application and wearing of jade is based on moral and spiritual reasons.
