There should be a time limit, and you won't be allowed in after the specified time. The school should send a notice saying that it should cooperate with the school to do a good job of leaving school for graduates and ensure that students leave school smoothly. According to the current requirements of preventing and controlling COVID-19 in schools, the library provides students with a safe and convenient way to return books (compensation) on the principle of providing convenient services, avoiding crowd gathering and reducing contact. When will the book lending service for graduates stop this year? All students who are about to graduate must go through the formalities of returning books as required before the time of leaving school determined by our college. If you want to enter the library, you can borrow a card from your junior, so you should be able to enter.
