Many years ago, my relatives in Guiyang gave me a kind of mushroom called winter mushroom (not Taobao mushroom, flower mushroom and so on). It's not strong, the taste is crisp and the soup is crisp.

If so, we Guiyang people call it "frozen bacteria". The official name is "Pleurotus ostreatus", which is too common. Basically, fresh food is sold in farmers' markets all over the country, and there are many dry goods. Most of them are artificial, and so are natural ones.
