However, people just misunderstood the true meaning of this sentence literally.

It is true that people raise jade. Because before Qianlong of the Qing Dynasty, the so-called jade in China culture was mostly Hetian jade in Xinjiang, and a few were Lantian, Xiuyan, Agate and Duyu. These are nephrite. Emerald is jade, which was regarded as jade only in Qing Dynasty. ) nephrite has low density and relatively loose structure. After wearing for a long time, human sweat, grease and other secretions will penetrate into jade, changing its appearance characteristics, becoming shiny and shiny, and even patina will appear after a long time. You can also make the appearance of nephrite change greatly in a short time by the method of coiling. That's why people raise jade, but this only refers to nephrite.

The so-called jade nurtures people does not mean that jade is beneficial to human health. So far, there is no scientific evidence to prove this statement. Theoretically speaking, the trace elements separated from jade can be ignored and cannot be absorbed by human skin. On the contrary, if some jade itself contains radioactive substances, its radiation will also cause harm to human body. For example, pearls can be used for beauty, but wearing pearls can't achieve the beauty effect, and it needs to be ground into powder to play its role.

The ancients believed that jade had the virtue of a gentleman. If you wear and play with jade all the year round, you can always remind yourself of self-cultivation and gradually improve your moral cultivation. This is the true meaning of jade nurturing people.
