I don't think it is necessary to rent a house outside the school when the family's economic situation is not particularly rich. The average school accommodation fee is between one year1500-2,500, generally four or six people. If you rent a house outside, even if you share it with others, it will cost 1 0,000 a month, and the house is not necessarily large, but it will cost about 8,000 a year. The second reason is that I think living in the dormitory is also to experience life and exercise communication skills. If you want to escape because you hate someone and can't stand it, you can't find a way to escape every time you enter the society, and you can't change jobs when you meet colleagues you don't like. So I think it is necessary to exercise your ability to communicate with others, and it can also enrich our college life. In case you can make like-minded friends, it is also very good. Another reason is that it can cultivate our living habits, such as cleaning in time and so on. Of course, it is a good idea to rent a house outside if the economy permits.
