It's not that libraries can't be open 24 hours a day, but that most of our colleges and universities don't have such conditions. The 24-hour opening of the library actually means that the teaching and auxiliary functions of the whole school should be open to the public 24 hours a day.

If you don't believe me, let's assume that the library is open 24 hours a day, and the library needs to recruit more people to increase night shifts. At the same time, student dormitories must be open 24 hours a day. Some people can brush the night in the library, others can't, and stay in the library until midnight. At present, few university libraries can match beds and sofas in reading rooms. Even if the conditions are superior, what should I do if snoring is annoying? If you don't want to sleep in the library, you must go back to the dormitory. The housekeeper downstairs stayed up all night watching the door waiting for you to come back?

I haven't been to a foreign university, so I don't know. Probably because people are completely open, students can rent a house and come and go freely. Schools don't need to consider such meticulous and possible problems, just concentrate on driving. However, most universities in China do not have the ability to open to the society, not to mention the 24-hour opening of libraries.
