Introduction to the library: is a two-story brick and wood structure building with five rooms in width, a hard hill, and a rolling shed style. It is the last entrance to Songyang Academy. It was a place for storing books in ancient times. It originally contained more than a thousand books, but most of them have been lost. Only some books from the Qing Dynasty version remain. Currently on display are "Er Cheng Complete Works", "Er Cheng's Posthumous Letters", "Four Books and Five Classics", "Zhongzhou Taoism Collection", "Four Books Near Reference", "Essentials of Neo-Confucianism", "Shuowen Jiezi", etc. In addition, there are still some woodcuts and inscriptions of some books in Songshan. The rare national treasure "Golden Slips of Empress Wu of the Tang Dynasty" discovered in the area is available for tourists to view.
