Tianyi Pavilion is the oldest existing private library in China, located on Tianyi Street on the west side of Moon Lake in Ningbo City, Zhejiang Province, China.
Tianyi Pavilion was built in the 40th year of Jiajing in the Ming Dynasty (1561), and was presided over by Fan Qin, the right servant of the Ministry of War at that time.
It not only collects a large number of precious books and classics, but also has a major impact on the construction of other libraries in later generations.
