In fact, in a broad sense, the boundary between North and south of China is along the Qinling Mountains-Huaihe River line. It is usually regarded as a natural geographical boundary, but it also has a great influence on the politics, economy and culture of ancient and modern China.

To this day, China is still affected by this natural geographical boundary. For example, North Jiangsu Province, represented by Lianyungang and Xuzhou, and South Jiangsu Province, represented by Nanjing and Suzhou, have great cultural and economic differences due to the barrier of the Huaihe River.

Another aspect is about China in the broad sense (56 nationalities currently recognized by China, as well as some naturalized nationalities in ancient times) and China in the narrow sense (Han nationality). In medieval China, North China is usually occupied by nomadic or semi-nomadic minority rulers in the north, such as Khitans, Manchus and Mongols. They integrate or naturalize the local Han people through intermarriage and various reforms. Most of the real Han people live in the south except the southwest where the Yi, Hmong and Dai people and so on live. These southern dynasties, such as the Song Dynasty, believed that they were the orthodoxy of the Chinese nation.
