After joining the army, the student status will generally be retained for 5 years, that is, it will remain valid after the expiration of service. Before joining the army, the school should submit the student's registration information and registration number to the local enlistment guidance office in order to establish the enrollment approval file. After the expiration of the service period, students can apply for resuming their studies, and they can still study normally after resuming their studies.

Joining the army means serving in active service. Like many countries, everyone has to perform military service and transfer to the reserve after serving for a period of time.
