Tour guides don't have this right. Don't think so much. The school is tough on the surface. At the beginning, people were not allowed to live outside in our university, but many people lived outside during the postgraduate entrance examination. Besides, tour guides generally don't check the dormitory. Does anyone know that you live in a dormitory? No one in my classmates will say that you may check it once a semester. As long as you are in the dormitory, there is another person in our class who has been living outside.
