Jade is a kind of precious stones, and Yunnan is one of the main producing areas of jade in China. According to the records of Zhi Heng in Yuhai, Yunnan, "Jade came out of the South Jinsha River, which once belonged to Tengyue", that is, the area of Lu Wu Valley in Myanmar, where jade was mined, was under the jurisdiction of Yongchang Prefecture in Yunnan during the Wanli period of the Ming Dynasty, so it was said that "jade was produced in Yongchang, Yunnan". In addition, Yunnan has a deep relationship with jewelry and jade, which has been recognized by many consumers. To a certain extent, it has become synonymous with jade, and "Yunnan Jade" and "Yunnan Jewelry" have become well-known brands at home and abroad.
