Jiangsu and Anhui regions north of the Yangtze River, Xinyang region in Henan, Hanzhong region in Shaanxi and Longnan region in Gansu are all vague. Su-Wan people north of Huaihe River do not consider themselves northerners, but take it for granted that Su-Wan is south. Hanzhong, Shaanxi, Longnan, Gansu and Xinyang, Henan are all at the southern foot of Qinling Mountains, but they think they are from Gansu, Shaanxi, and naturally they are northerners.

And many people think that the Yangtze River is the dividing line between north and south.

Except the Qinghai-Tibet Plateau, all other areas are recognized as north and south.
