The formation of northern and southern Jiangsu is based on the social environment such as geographical location, culture and folk customs, and it has been formed after decades of historical changes. The first is regional differences. Although northern Jiangsu and southern Jiangsu are both parts of Jiangsu, they face each other across the river. Before the Yuan Dynasty, most areas in southern Jiangsu and northern Jiangsu were under the jurisdiction of different administrative regions, which were divided into the Yangtze River and Huaihe River. Until the Qing dynasty was established? Jiangsu? Province, but in fact, the river is the rule, and southern Jiangsu and northern Jiangsu are regarded as two places, which is the starting point for the division of administrative divisions in Jiangsu Province. It is also for this reason that Sunan people prefer it? Jiangnan people? Pretend to be. Because of the separation of rivers, the inconsistency between the north and the south gradually began to become different. Suzhou, located in the north, is suitable for growing wheat, so the dietary structure has formed a dietary habit of giving priority to pasta and leaning towards the north. Pasta, jiaozi, steamed buns and pancakes are the staple foods. But in southern Jiangsu, rice is the main form of rice, and southern Jiangsu prefers glutinous rice. Throughout the year, a large number of pasta cakes appear.

Secondly, the difference in the level of economic development. Historically, the economic development of southern Jiangsu is higher than that of northern Jiangsu, with good economic strength and relatively good urban economic foundation, especially in the development of light industry, which has formed its own light industry system; However, northern Jiangsu has always been dominated by agriculture and fisheries, and its industrial base is relatively weak, and its economic development is not as fast as southern Jiangsu. Southern Jiangsu is close to the core of the Yangtze River Delta, closely linked with Shanghai and Hangzhou, and relying on the ocean, it can better export products produced by light industry, which provides good convenience for the development of southern Jiangsu. Most of the national and provincial supporting transportation construction funds are invested in southern Jiangsu, which makes the external communication channel in northern Jiangsu lose the key factors of economic development and transportation first. Third, the tax policy is unbalanced. Some preferential policies given by the state to Jiangsu are mostly in southern Jiangsu, such as comprehensive bonded zone, export processing zone, experimental zone, experimental zone and foreign-funded enterprises.

Finally, there are cultural differences. The economic differences between southern Jiangsu and northern Jiangsu have caused the differences between the two places, as well as the cultural differences. People who grew up in northern Jiangsu have the habits of northerners, are full of heroism, are particularly measured about people and things, and have low requirements for quality of life. They believe that the so-called heroes should aim at all directions and make contributions, so there are many military commanders in history, and northern Jiangsu prefers simple and simple buildings in architecture. People who grew up in southern Jiangsu are even more humble and modest. They always take building a family, raising living standards and improving their lives as their lifelong goals. They believe that hard work can make them rich. When people in southern Jiangsu have money, they usually build houses on the land, train their descendants to study, test their fame and honor their ancestors. When they have money, they can build houses on the land for business, thus promoting economic development and forming a virtuous circle. Therefore, there are many gardens and talents in southern Jiangsu.

To sum up, the formation of northern Jiangsu and southern Jiangsu can not be seen alone, but should be comprehensively analyzed. Welcome everyone to discuss together.
