The masks on Pinduoduo are horribly cheap. Can you buy them?

General protection should be ok. The masks we usually wear now are all bought from Pinduoduo, which seems to be only 0. 1 yuan. There seems to be no problem when we buy big bags. However, if you are a medical worker or a worker who may be exposed to the epidemic, it is still recommended to buy it in a qualified pharmacy or hospital. After all, it is more reliable, and you should protect yourself. May everyone be safe.
