List of administrative divisions of Shanghai
Shanghai is one of the four direct-controlled municipalities of People's Republic of China, and is further divided into 16 districts. Seven of the administrative districts together make up Shanghai's "urban core", and there is no single "city centre" district amongst them, although Huangpu District contains most of the traditional city centre area of Shanghai.
