Located in the southwest of Shanghai, Xuhui District is centred on Xujiahui, after which it is named. Being the core of Catholic Shanghai, Xuhui District formed, together with neighboring Luwan District (now Huangpu District), the former French concession of Shanghai. Vestiges of the French influence can still be seen in the St Ignatius Cathedral of Shanghai, Xuhui College, the Xujiahui Observatory, and some remaining boulevards and French-style areas. A number of former residences of prominent personalities remain, including Soong Ching Ling and Sun Yat-sen's former residence. Yao Ming of Houston Rockets was a resident of the district.
