A "gourmet" who affects others' learning.
Some students bring snacks into the library and throw them away after eating. This behavior not only affects the learning atmosphere in the library, but also brings discomfort to other students.
The book is out of order.
Some students put away their books after reading them, while others even hide them in order to borrow more books. This behavior not only brings inconvenience to other students, but also troubles librarians.
Book destroyer
Some students scribble on books, tear off pages and even take books out of the library. This behavior not only violates the regulations of the library, but also affects the reading experience of other students.
Seat-occupying clan
Some students sit early, but they are playing with their mobile phones and sleeping there. Such behavior not only wastes seat resources, but also brings inconvenience to other students who really need to study.
