If you want to send something by post, there is a unified format, that is, the address is "new # # mailbox of the new campus of Shaanxi Normal University" and the postal code is 7 10062. In this way, things will arrive at your mailbox accurately.
If you use various courier services such as Shentong, the address can also be written in this way to ensure that it can be received smoothly.
Because I have mailed things, hehe.
