The second floor on the west side of the south gate is the mailroom of Zhongxiu Campus. If it is a surface mail parcel, you must first have proof that the parcel has left (there is usually a palm-sized piece of paper in the class mailbox, so you can only find it by asking your monitor for the key). Take the certificate and ID card or student ID card to the second floor to pick up the parcel, and then take the parcel to the shop of the small post office outside the south gate for the staff inside to help you pick it up. It will cost you about 80 cents, but it won't exceed two yuan in any case. If you want to collect it yourself, take the parcel form to Yijiaqiao Post Office, and the address is on Baidu map. Personal experience advised the landlord not to worry about money. I searched the post office twice and couldn't find it, so I took it all for him ~ ~ ~
If it's a surface mail letter, first see if it's sent to your class's mailbox, and then ask your monitor for the key in the mailbox. If there is no mailbox on the envelope, look for it on that glass window. Many letters have no specific address, only the address of the school.
Also, whether it's a letter or a parcel by surface mail, there's no phone call or information notice. If it's overdue, you still have to pay a storage fee ~ ~
