BI3BUV If you need services for individuals, using a broker will cost more, but it can be handled with company use. Some cities have specific requirements for individual service requests; you should go to the city-level postal company's integrated office (not the regular post office, but the office building behind it). If you don't want to spend extra money, you can send everything through one box. Buy a mailbox and place it at the delivery station (either the delivery department or a convenient courier station) so that the delivery person can put your mail in there. You only need to provide the address: A province, B city, C district, D street, C mailbox. For receiving mail, just use the mailbox at the delivery station; for returning mail, it will be returned to the delivery station.
