The poor economy in northern Jiangsu can only go to southern Jiangsu, and any city in northern Jiangsu is a strong city in other provinces. For example, Anhui, which puts Yancheng next to it, can rank second. The model adopted by Jiangsu is to give priority to the development of southern Jiangsu, which is the route of national reform and opening up, and all provinces take the same road. Jiangsu's policy resources are given priority to southern Jiangsu, making southern Jiangsu rich and driving northern Jiangsu.
