What do you mean, China Post Express has signed for it?

You don't have to pick it up yourself, which means it has been sent to the nearest branch or processing point. It is estimated that it will be delivered to you today or tomorrow. If the query results show "Normal Delivery" status, it means that the delivery is completed and someone has signed for it.

If it's not EMS or e-mail, don't worry, just go to the post office to pick it up after receiving the express bill.
