Shanghai Municipality sits on the Yangtze River Delta on China´s eastern coast, and is roughly equidistant from
Beijing and Guangzhou. The municipality as a whole consists of a peninsula between the Yangtze and
Hangzhou Bay, mainland
China´s second-largest island Chongming, and a number of smaller islands. It is bordered on the north and west by
Jiangsu, on the south by
Zhejiang, and on the east by the East China Sea. The city proper is bisected by the Huangpu River, a man-made tributary of the Yangtze that was first excavated and created by Lord Chunshen during the Warring States Period. The historic center of the city, the Puxi area, is located on the western side of the Huangpu, while the newly developed Pudong, containing the central financial district Lujiazui, was developed on the eastern bank.
