Why is Jiangsu Province in the south and Lianyungang in the north?

Except Xuzhou, Suqian and Lianyungang, most of Jiangsu Province should be in the south. China is bounded by the Qinling-Huaihe line in the north and south, with the south belonging to the south and the north belonging to the north. Lianyungang is actually the real intersection of north and south. In terms of diet, Ganyu County is dominated by pancakes, similar to Shandong. In other areas, the staple food is rice and pasta. Real northerners, such as Inner Mongolia, will think that Lianyungang is the south, but it still belongs to the north. Southerners love sweets, while northerners love peppers. The weather is also northerly, windy and cold, not as rainy as in the south. Linguistically, it is also the north, and Linyi dialect in Shandong Province is spoken in Ganyu District. In short, Lianyungang is a northern city, which is more in line with people's consistent cognition!
