Check the beds in the university. According to relevant public information, universities generally have a dormitory management system, so they will check the beds. Some schools stipulate that you must rest in the dormitory at night and not go out. If someone leaves the dormitory, they will be warned or punished, including points deduction, fines, power failure and so on. In addition, some schools will check students' sleep before exams or especially important activities to ensure that students rest and prepare on time and according to regulations.
