The great traveler Xu Xiake also witnessed the grand occasion of jade trade at that time when traveling, and wrote it in Xu Xiake's travel notes.
It can be seen that the time when jadeite was introduced into China was in the middle of Ming Dynasty, but the official history did not leave the specific name of who was introduced.
Leaving only one legend:
In the middle of Ming Dynasty, there was a caravan doing business on the Yunnan-Myanmar border. On a business trip, the road was bumpy and the tea was shaken off, so the captain of the caravan picked up some big stones to press the goods. When I got home, a stone fell to the ground and wore a little skin, revealing the green jade meat inside. The caravan leader liked it very much and entrusted a jewelry store to build a set of jewelry for his wife and daughter.
Later, this new jade became more and more famous and popular, because its color was like the feather of a kingfisher.
Gu Dingming is called emerald.
