Hello. Only students who live on campus can stay in school without restrictions. As for day students, they are limited by time (for example, they don't open the door in the morning and close it at night). Also, it is more difficult to let students from other schools enter the campus. Local schools are maintained by social security, and are managed by doormen all the time. Finally, it is an open day, and it is also allowed to enter during the day. I wish you all the best, health, happiness and happiness. Please adopt it. Thank you.
