How long does the courier leave after disinfection?

Now, after entering China, all international express mail will be sent to the three exchange offices in Beishangguang. Disinfect for 24 hours after entry and 24 hours after arrival at the exchange office. Because international mail is hexagonal, after the first sealed space is disinfected, before it is sent to the second sealed space, staff will turn the mail over to ensure that the sixth side can be completely disinfected. After disinfection, the corresponding mail will stand for 24 hours, and then submit it for inspection so as to be distributed to various sites for delivery.
