mber of visitor?РNowadays, it is ing increasingly popular for tourists to visit famous universities such as Peking University and Tsinghua University during the holidays. However, some universities decide to limit the number of visitors, which has caused heated argument in China.РI think the number of tourists should be limited. Here are my reasons: first of all, there are too many tourists wandering through the school yard, teaching buildings, or even the library, which has a negative effect on the students who are absorbed in learning. Second, with so many ing, it is harder for security guards to keep order. Third, universities are designed to provide education rather than tourism service.РIn summary, universities should limit the number of tourists to ensure a good learning environment.
