There is no special mailroom in Neida South Campus. Ordinary mail letters are sent directly to all colleges, and then put into the mailboxes of all classes, and the staff of the class teacher will open the box regularly to get the letters. If it is a registered letter or express mail, it will be sent to the offices of various colleges and kept by a special person. The name of the recipient is written on the small black board outside, and you can collect it with a voucher.
