What are the origins of bloodstone China?

Bloodstone mainly refers to red stone made of mercury sulfide. At present, there are many places in China that produce bloodstone. Judging from the mining history, Changhua and Bahrain have a long history, and the frozen soft bottom is better.

In recent years, bloodstone has also been produced in mercury mines in Wanshan Sandu, Guizhou, Xunyang, Shaanxi, Hunan and Sichuan. Moreover, these newly opened bloodstone are not expensive because of their short history.
