The Taobao store writes that fake goods will be fined ten times for fake goods. Is it true?

It is true, but it is difficult to prove. Generally, specialty stores will help you check whether it is genuine, but when you ask them to issue a certificate for you, they won't give it to you. Because there is no official fixed format for this certificate, and the salesperson in the specialty store will help you read it personally, so it is basically impossible to get the certificate.
