Of course. Freshmen who can't report on time due to special circumstances must call the school student office for leave. Those who fail to report for a week without reason are deemed to have voluntarily given up admission. After going through the formalities of asking for leave, as long as there are justified reasons, it is estimated that the problem will not be great within one week, depending on how many days the school will reply. Most colleges and universities will attach a new student admission guide or new student registration notice when mailing the admission notice of deferred materials, and new students should pay attention to this when registering.
