But I still brought my computer. When I was a freshman, there was no locked box in the dormitory, so every time I went out, I put away my computer from the innermost part of the wardrobe, pressed it with a quilt or something, and then locked the big lock in the dormitory. In this case, if my computer is lost, I can only pry open our door and steal it (this is actually called robbery).
Computers and mobile phones are often lost in some of our dorms. As far as I know, the management of uncle reception rooms in those dormitories is not very strict. Anyone can enter, and then someone will hand out leaflets and sell them to the dormitory to steal things.
Some schools will be equipped with dormitory safes (depending on the school), and the cost of installing safes in our school is about 100 yuan a semester, which is not expensive.
In short, as long as you are careful, you must lock the door when the dormitory is empty. I don't think you will leave your computer in a conspicuous place. Thieves only steal what is easy to steal. If you take precautions yourself, thieves will naturally stay away from you.
