The origin of place names:

Xu Guangqi was a great scientist in the Ming Dynasty who had great influence in the history of science in China. He devoted his life to the research of astronomy, calendar, mathematics, water conservancy and agriculture, co-edited the Elements of Geometry with Matteo Ricci and wrote the Encyclopedia of Agriculture.

He once lived and worked in Shanghai, ran a farm at the intersection of Hongqiao Road, Puhuitang Road, Zhaojiabang Road and Huashan Road, engaged in agricultural scientific experiments and devoted himself to writing books. Since then, his descendants have lived in this area for a long time, so there is the origin of today's Shanghai "Xujiahui" place name.
