If it's overdue, can I renew my vacation on campus today?

Today's campus holiday can be extended if it is overdue. According to the relevant public information, students who can't take the domestic leave within the time limit must go through the formalities of making up the leave in advance. If it is impossible to take written leave in time under special circumstances, parents should have WeChat or SMS to inform them of the reasons and time for not being able to cancel their leave on time. After approval, they can extend their leave and go through the procedures for extending their leave.
