The mailbox of the president of Guangxi University of Science and Technology has been read. Because this is handled by the headmaster himself, if students are dissatisfied with some situations on campus and find some loopholes, they can write to the headmaster's mailbox anytime and anywhere. Today's mailbox is also very different from the previous mailing mailbox. The headmaster will mark his email address on it, and students can contact him anytime and anywhere. The headmaster will deal with the letter in time after receiving it.
