What does ZTO Express mean by asking me to provide Ali Wangwang's name for no reason? I returned it to the seller. The refund process has been successful. Why did I win?

No matter what the other party means, it is never a good thing for the courier to ask you for Want Want ID. If the seller needs your Want Want id, you can check it backstage. Although Want Want id can't create any information security problems for itself, it can be completely ignored. It is also possible that the courier sold your id to your colleague who returned the goods. Hand, hope to adopt.
