Jade feels sticky. Is it Hao Yu?

Jade is easy to touch and sticky. Some good jadeites are indeed lipophilic, and human sebum will become shiny after "moisturizing". Lantian jade and Hetian jade are the first choice for good jade. These two kinds of jade are aquatic jade, which complement each other with human breath and body temperature and induce each other.

I'm afraid it's difficult to verify exactly when people wear jewelry. However, it is not difficult to infer that from the time when human beings began to realize the decoration and beautification of themselves, human beings also formed an indissoluble bond with them. The most primitive jewelry of mankind can probably be traced back to the distant Stone Age.

From the data of Paleolithic and modern primitive tribes found all over the world, people can find that the early primitive human body ornaments are mainly necklaces, waist ornaments, arm ornaments, wrist ornaments, headdresses and so on.

Among these forms, necklaces and waist ornaments are the main ones. To a large extent, they are decorated around the reproductive area of the human body. The reason is that these parts have the ability to support the wearer, and a large number of studies show that this choice has another purpose.

Animals' colors and patterns are also a kind of body decoration. The natural ornaments, headdresses, necklaces, chest ornaments and tail ornaments of male birds often change and display regularly during the breeding season, which are quite effective in attracting the opposite sex.

A large number of biological materials prove that the beautiful decoration of animals has great advantages in the process of sexual selection. Human body tattoo is a form similar to body decoration, which is a qualitative change of the extension of animal natural decoration.
