Excuse me, how do college students ask for leave for half a month, that is, they are half a month late for school?

First of all, contact the counselor of your grade in your school and explain the reason for taking time off. Then I will approve the leave. During the leave, I will write a note in each class, stamp it, leave it to my roommate and give it to the class teacher. It can be said that train tickets are particularly tight during the term of school, so they can't be bought. Anyway, the pre-sale period is within 15, so you can say that the train tickets within 15 days are gone. Or you can tell your family that if you don't go away, your distant relatives can't buy tickets to go home and can't go back to school, which is natural ~
