How long will it take for the courier to be returned?

7- 10 days. If it arrives at the receiving place soon, if no one receives it, it will be returned within 7- 10 days. Because no one received the express mail, the recipient could not be contacted. After more than 7 days-10, the express mail had to be returned to the original sending place. However, if the goods are only received by contact, it means that the goods will be delayed at the situation level, and the courier unit will not send the courier back to the original place. However, when receiving the goods, you need to pay the express storage fee, which is about 1 yuan/day.
