I bought something from Taobao, which was very bad and gave a bad review. Recently, the store owner always sent me messages, asking me to change my evaluation and return to the original me.

You don't need to worry about this problem at all! Let him do multiple-choice questions, only he can cash back first, and then you can change the evaluation! It would be bad if he didn't dare to take risks. If he doesn't ask for anything in return, he's already in pain. It's normal to give him bad reviews. If you change the evaluation first, and he doesn't give you cash back, then you will take the poor quality goods and give them high praise without conscience, which will kill him, but you won't get any compensation and suffer at both ends.
