Haimen, Nantong

The area that is now Haimen was formed from silt deposits from the Yangtze River. Several sandbanks, including Dongzhou () and Buzhou (), joined with the mainland in the Tang dynasty. In 958 CE, during the Later Zhou dynasty in the Five Dynasties and Ten Kingdoms period, Haimen County was established with the county seat at Dongzhou Town. At this time, Haimen and Jinghai District () were merged into the newly formed Tongzhou District (). Because the mouth of the Yangtze River moved northward during the Ming dynasty, Haimen has dealt with flooding that destroyed parts of the county, including Lüsi (), Yudong (), and Sijia (). == Economy ==
