The border between Shaanxi and Shanxi

The dividing line between Shanxi and Shaanxi is the Yellow River. The Yellow River is the natural dividing line between Shanxi and Shaanxi. The Yellow River flows through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong provinces, and finally flows into the Bohai Sea.

The Yellow River is a big river in the north of China, belonging to the Pacific water system. The main stream is arc-shaped, which is called "Jiuqu Yellow River". The actual flow of the river is 2.64 times of the linear distance from the source to the estuary. There are many tributaries of the Yellow River, from Maquguo in Heyuan to the estuary, which flows directly into the Yellow River along the way. There are 220 tributaries with a drainage area of 100 square kilometers, which constitutes the Yellow River water system.
