Where is Haimen located in Jiangsu? Is it southern Jiangsu or northern Jiangsu?

Hello. Haimen is a county-level city under the jurisdiction of Nantong City, Jiangsu Province. In the southeast of Nantong, across the river from Shanghai.

Geographically, there is no distinction between southern Jiangsu and northern Jiangsu, which is a general division of Jiangsu Province. It is customary to call the cities north of the Yangtze River Central Jiangsu or Northern Jiangsu. So Haimen should be Su Zhong.
