First of all, schools are allowed to rent houses outside, and the accommodation management of each school is loose and tight. There will be students who are forced to pay accommodation fees to live inside, and there will be students who are forced to pay accommodation fees but can live outside. Individual schools can choose their own residence without paying accommodation fees. In short, according to the cost performance ratio, if the accommodation fee on campus is paid but useless, it is equivalent to wasting a sum of money. Of course, friends who don't care about money can ignore this. Hahaha, the main contradiction lies in the tolerance of the school system.

Secondly, whether the individual's lifestyle adapts to the group life, and whether it is possible to apply for medical certificates and stay outside under special physical conditions. It is not excluded that some students can't adapt to dormitory life. It may be that the living habits of dormitory members cannot be coordinated, or it may be that they need to live outside for their own physiological or psychological reasons. At this time, you need to apply for living outside.

Finally, there is a special stage, such as the next semester of junior year or the whole school year of senior year, which is almost the stage of internship or postgraduate entrance examination. It is more convenient to rent a house off campus. It is necessary to rent a house near the internship site where the environment is relatively quiet and suitable for preparing for the exam.
