The etiquette system stipulates the relationship between jade and men. Even wearing jade is not as aesthetic as jade ornaments worn by modern women, but mainly carries a moral function. There is a saying in Jade Algae that "a gentleman can't go without a reason". In addition to the moral symbolic meaning of "a gentleman is better than jade", it also contains the meaning of restraining men's behavior by wearing jade. The jade that "jade does not go to the body" mainly refers to Yu Pei. Yu Pei's attention to Yu Pei, an ancient man in China, is divided into two groups, that is, the meaning of "Yu Pei must be double". Each group is a vase, and each vase consists of seven pieces of jade with patterns of clouds, dragons, algae, snakes and forests. The horizontal jade worn on it is called "honing jade", which is shaped like a horn or a residual ring. The upper end of the honing jade has a hole for threading and hanging on the belt; There is a hole in each corner of the jade, and there is a hole in the middle, which is divided into three groups, all of which have ribbons or pearls passing through. The middle part of the middle group is a round jade called "Jun". There are three holes in the upper and lower parts to connect the upper and lower parts. A piece of jade hangs at the end, shaped like a half wall and pointed at both ends, which is called "tooth punch". There is a hole in the middle of the semicircle of the punching tooth for connecting the belt. In the other two groups, there is a jade hanging in the middle, and there is a hole in the upper and lower parts to connect the upper and lower parts. At the end of the lower half of the group, there is a piece of jade, which looks like a half, and the two pieces of jade are opposite and look like a whole wall. When people walk, these three groups of jades collide with each other with people's actions, and their collision sound was called "Hengdang Pei Huan" in ancient times.
