It may also be because of a major accident at home.

Or join the army.

Or because of the special period now, I have been in contact with close people or people who have been diagnosed.

It should be noted that you must contact the school in advance to apply for extension of admission and explain the reasons. Generally, the admission time will be extended by two weeks at the latest.

The Notice of the General Office of the Ministry of Education on Doing a Good Job in the Admission of 20 17 Compulsory Education clearly states that student status is the result of students' admission, not a prerequisite for admission and transfer. Its main function is to record, transfer or create a new student status, which is the later procedure of enrollment, and students should not be refused on the grounds of student status. After students enter school, if they already have a student status, the receiving school should transfer their student status through the national student status system to achieve "consistent citizenship"; If you have no student status, you should create a new student status.
