Assuming that the student's loan application period is 6 years, it means that the student needs to pay off the loan principal and interest within 2 years after graduation. If students apply for a student loan for 8 years and continue to study after graduation, it means that students need to pay off all the loan principal and interest within one year after graduation.
It is worth mentioning that the interest generated by students' loans during their school days is subsidized by the state finance, and students do not need loan interest during their school days.
