Don't check the dormitory at night, 10: 30 close the building door, and you can call to open the door when it is closed.
There is no mandatory accommodation requirement. Postgraduates can apply for off-campus accommodation when they enter school, or they can apply for off-campus accommodation at the end of each semester, and they can stay in the next semester.
Graduate students do not exercise standing up, nor do they check the number of people in the morning and evening. It's no problem to go home and live. Graduate students are very loose and do their own thing, as long as the tutor doesn't suddenly look for him.
