Some scholars who study the history of libraries in China believe that "because culture is monopolized by the ruling class, books and documents are regarded as private treasures, and not only private collections' books don't marry', but even national collections are regarded by the emperor as' retiring from the DPRK to entertain themselves' and belong to the royal family. The readers of the library are mostly book owners, and the whole library is in a relatively static and closed state, so people call the library in this period' library building' or' library office'. "

Others further infer: "A person lends his books to strangers to share with others, or simply turns his own things into public things, which requires a premise. Everyone in this society, at least most people, must have public awareness." Obviously, only in a society with such public consciousness can a person share his personal things with others. The earliest public library in the world was developed on the basis of private literature public ownership. In this way, the ancient west had such preconditions in a sense, while the ancient China did not. "
