1. The Museum of Classical Books in the National Library is the focus of this comment; 2. The Museum of Classical Books contains all kinds of precious materials, such as collections of classical literature, manuscripts of modern celebrities, documents of founding merits; 3. The Museum is free, but it can't bring shoulder bags and drinks into the museum, so it should be deposited; 4. Sometimes there will be some special exhibitions, the latest exhibition of oracle bone inscriptions, which is worth seeing.
