天津港
The Port of Tianjin ("Tianjin Gang", ), formerly known as the Port of Tanggu, is the largest port in Northern China and the main maritime gateway to Beijing. The name "Tianjin Xingang" (), which strictly speaking refers only to the main seaport area, is sometimes used to refer to the whole port. The port is on the western shore of the Bohai Bay, centred on the estuary of the Haihe River, 170 km southeast of Beijing and 60 km east of Tianjin city. It is the largest man-made port in mainland China, and one of the largest in the world. It covers 121 square kilometers of land surface, with over 31.9 km of quay shoreline and 151 production berths at the end of 2010.
