Introduction to the library: The library in Huihe Hall is also known as the "Jingguan Tower", which is taken from the poem "A Bottle of Wine in the Comfortable Nest" by Shao Yong, a poet from the Song Dynasty. This is Wang Hao's study place. It was built in the 11th year of Chenghua in the Ming Dynasty (1475). After Wang Hao was admitted to Tanhua, his father Wang Wan resigned and returned home. This building was built to encourage him to continue his studies. In the late Chenghua period, after his grandmother Yeshi and his father died of illness, Wang Hao stayed at home for six years and completed "Gusu Zhi", "Zhenze Bian", "Chunqiu Mingci" and other works in this building. After that, this building became the embroidery building of Miss Ye’s family, so it was also called Miss’s Building.
