The library is the key fire prevention unit, but whether you can smoke in the library now depends on the regulations. Some school libraries will not ban smoking, and there will be ashtrays in the toilets, so smoking is understandable, but some will stipulate a total ban on smoking, which is clearly written on the wall, so smoking in the library toilets in this case is not a sign of public morality.
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, libraries appeared. Library has the functions of preserving human cultural heritage, developing information resources and participating in social education. Library is the external storage and selective transmission mechanism of social memory (usually expressed in written records). In other words, the library is the memory device and diffusion device of social knowledge, information and culture.
