There are many ways to send letters. Method 1: Each class has a class mailbox, such as the mailbox of Guangxi University West Campus 148. Method 2: If you don't have or can't remember the class e-mail, you can directly write down the professional class of a college, such as Class 2 of 2007 Mineral Resources Engineering of College of Resources and Metallurgy of Guangxi University. Method 3: You can send it to the dormitory, such as Room 32 1 in Building 6, East Campus of Guangxi University.
The postal code is 530004.
Receiving methods, methods 1 and 2 are generally handed over to the receiver by the class Committee. The third method is the reception of the dormitory building management, and the building management will take the letter to the recipient or send a notice on the blackboard downstairs for the recipient to receive.
