PO HAI

Pinyin Bo Hai, also called Gulf Of Chihli, shallow northwestern arm of the Yellow Sea, off the North China coast. It is enclosed by the Liaotung Peninsula (northeast) and the Shantung Peninsula (south). The broad Gulf of Liaotung on the northeast is generally considered part of the Po Hai. Within these limits, the gulf's maximum dimensions are 300 miles (480 km) from northeast to southwest and 190 miles (306 km) east-west. The strait leading to the gulf is about 65 miles (105 km) in width. The Huang Ho (Yellow River), China's second longest river, discharges into the gulf. The gulf has long been used as a source of prawns and salt. There are both onshore and offshore petroleum deposits, and several oil refineries are located there.
