There are libraries in Changsha, including Hunan Provincial Library, Hunan Children's Library and Changsha Library. They are all public libraries, and they are all free to borrow. The new Hunan Provincial Museum and Children's Museum have been open for many years, and the new Changsha Museum has just been completed, but I don't know if it is open. Search Hunan Provincial Library and Hunan Children's Library. On the main page, you can query the contact number and address, or you can directly retrieve the book catalogue.
