I am a senior three student. . During my three years in Jiangning, I have never heard of being able to stay out of it. I have a junior and a sophomore. Her home is in Jiangning, which is very close to the school and has no home. Besides, Nanyi has always been known for being old-fashioned. So, it should be impossible.
Moreover, most senior students in our department live on campus, although the conditions are poor. Even if they can go out to rent a house or live at home in Nanjing, they have to pay the accommodation fee as usual.
Jiangning dormitory is strictly controlled, not to mention.
