1.At the beginning of the 20th century, amphibole jade was officially discovered in Xiuyan County, Liaoning Province, and was named Xiuyan amphibole jade. In fact, Xiuyan flash jade was discovered in ancient times and used to make jade articles. However, in ancient times, jade was named after place names, not Xiuyan flash jade, but was called old jade and Hemo jade by local people, which also shows that jade workers have long discovered the difference between this kind of jade and xiuyan jade. Modern scholars use modern scientific and technological means to prove that tremolite nephrite exists in xiuyan jade and does not belong to serpentine.

2. Professor Wang Shilin from Peking University made many reports on Xiuyan Flash Jade. In addition, Xiuyan amphibole jade is different from Xinjiang amphibole jade and Hetian jade. The discovery of hornblende jade in Xiuyan provides a reasonable explanation for the origin of hornblende jade in Xinglongwa Culture and Hongshan culture jade. On August 7th, 20001year, Shenyang Daily published the article "Tremolite White Jade Discovered in Xiuyan", which confirmed that Xiuyan County, Liaoning Province is a major source of ancient white jade.
