First, students just entered the school and don't know much about other students in the dormitory. Besides, they are busy with all kinds of things, so it is difficult to take care of their valuables. If they lose because of carelessness, they will lose a lot.
Second, it is easy to cause "contradictions" when freshmen bring laptops to school. Roommates will help each other, but once or twice is acceptable. After a long time, everyone will complain. If your roommate often borrows your computer, it's hard to refuse.
Third, the freshmen have just started school, and the students have not recovered from the idea of playing. If they buy laptops again, it will be more difficult to clean them up, and they will be addicted to the internet and games easily, which will not help their future development.
Generally speaking, for those freshmen with good economic conditions who need majors, it is not necessary to bring laptops. After all, there are not many places to use, so there is no need to waste money.
