I think it is necessary to set up access control. The university dormitory is crowded with people, and many people live in it. All kinds of foreigners who do business blend into the dormitory. Although we can buy some things sometimes, it also brings various disadvantages. When I was at school, I often heard that there were always people walking in the corridor outside the girls' dormitory, and the incidents of losing money and things were the most. Because there is no access control, the building management always gives others an opportunity when they are not careful, and it is impossible to install monitoring in the dormitory road.
