You can take a year off to study again. According to the local welfare life, in principle, university suspension is handled within the first week after the start of each semester, and the suspension time is one year. If a student really needs to drop out of school due to illness or something, he must submit a written application with relevant certificates. The patient needs to show the diagnosis certificate of a third-class first-class hospital (generally hospitals above the county level belong to third-class hospitals), and those without diagnosis certificate or seal are invalid. Due to the disease diagnosed by the school hospital or the hospital designated by the school, it is necessary to suspend classes for treatment and rest, accounting for more than one-third of the total class hours in a semester. For other reasons, I applied or the school thought I should drop out of school. Students who apply to join the China People's Liberation Army (including the Chinese People's Armed Police Force) and participate in the western volunteer service program shall be handled in accordance with the relevant provisions of the state and schools. During the permitted study period, students' suspension time is generally one year, which may be extended appropriately with the approval of the school under special circumstances, but the cumulative period shall not exceed two years. Upon the expiration of suspension, students should submit a written application for resumption of schooling to the school before the start of the semester. Students who drop out of school due to illness should also hold a medical certificate from a hospital at or above the second level. Only after passing the physical examination in the school hospital can they go through the formalities of resuming school.
