I suggest you buy salted fish. You can't read Taobao. 90% is counterfeit money. Part of it is true, but you can't identify it. You can go to salted fish to see what is missing, that is, buy some people who remove powder or exchange money. This is hard to say either. Depends on whose autograph you want to buy. I can take a look at it for you. You can ask me questions when you find a picture in salted fish. I can help you identify it.
