Introduction to Guangqi Park: Guangqi Park is located on Nandan Road, Xuhui District, Shanghai. It was once named Nandan Park. In 1983, it was renamed to commemorate the 350th anniversary of Xu Guangqi’s death. The main building in the park is Xu Guangqi’s tomb. In 2003, Nan Chunhua Hall, the oldest existing residential building in Shanghai, was relocated to it for rescue and protection and was opened as Xu Guangqi Memorial Hall.
