Introduction to Xujiahui Hall: Xujiahui Hall displays in detail the history of Xujiahui and the achievements of famous politicians and educators such as Xu Guangqi and Ma Xiangbo. In Xujiahui, Xu Guangqi, a great scientist, Minister of Rites in the late Ming Dynasty and a bachelor of Wenyuan Pavilion, built a farm here and engaged in agricultural experiments and writing books. After his death in 1641, he was buried here. His descendants built a house here to guard the tomb and thrived. It was first named "Xujiaku" and later became a village. In addition, the three waters of Fahuajing, Zhaojiabang and Puhuitang converge here, hence the name.
