You can tell your classmates that the library is closing. Please leave with your luggage as soon as possible.

So the students won't say anything, because everyone knows that the library closes at eight o'clock, which is understandable.

A library is an institution that collects, sorts out and collects books and materials for people to read and refer to. As early as 3000 BC, the earliest library appeared. Library has the functions of preserving human cultural heritage, developing information resources and participating in social education.
