First of all, it is unsafe for college students to rent a house outside, especially female college students. College students belong to the growth stage, their minds are not fully mature, their thoughts are still relatively naive, and they are easily bewitched by outsiders. At present, most of the deceived people are basically college students, because college students are simple. And outside, especially female college students, their health will also be threatened. After all, it's a society outside, and it's a mixed bag.
Secondly, the outside environment is more attractive to college students. Many college students just rent a house outside, and can't stand the temptation outside, so they are on the road of no return.
Finally, if college students want to have a good future, they must have certain skills, and it is better to learn these skills at school than outside.
