Meiyu is introduced as follows:

The implication of beautiful jade lies in auspiciousness, honesty and virtue of a gentleman. Meiyu is a symbol of auspiciousness, and its cultural reference in time also makes China people believe that jade has the connotation of faithfulness besides auspiciousness.

In the past, when people read letters, they always recognized seals instead of signatures. It is precisely because the imperial seal is a powerful credit report that people will seal it as a letter. What's more, many people give jade as a token to each other, and what's more, they give full play to jade's trustworthiness and honesty. Therefore, the implication of jade also means trust and honesty.

Jade is divided into nephrite and jadeite. Nephrite generally refers to white jade, sapphire, jasper and northeast jade produced in Xinjiang, China, while jadeite refers to jadeite produced in Myanmar. Whether nephrite or jadeite, their texture is very hard and their colors are very bright, so they are known as the king of stones.

The forming conditions of jade are extremely special and complicated. Most of them come from high-temperature molten magma tens of kilometers underground. These high-temperature mud rushed from underground to the surface along the cracks, and turned into hard stones after cooling. In this process, only some elements slowly crystallize into hard jade or precious stones, and their formation time is very far away from us. Jade is one of the earliest traditional handicrafts in China.

Dr Joseph Needham, a British natural scientist, once said: Love for jade is one of the characteristics of China culture. According to textual research, there were simple jades in China as early as the Neolithic Age. The most valuable jade articles were unearthed in the Chahai site in Liaoning Province 8000 years ago. Jade beads, jade tubes and jade blocks were found in Hemudu site in Zhejiang province from 6000 to 7000 years ago.
