The Yellow River originated in Maqu, Yuegu Zonglie Basin, at the northern foot of Bayan Kara Mountains in Qinghai Province, and it was zigzag. It flows from west to east through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong provinces, and finally flows into the Bohai Sea.
The middle and upper reaches of the Yellow River are dominated by mountains, while the middle and lower reaches are dominated by plains and hills. Because the middle section of the river flows through the Loess Plateau in China and carries a lot of sediment, it is also called the river with the largest sediment concentration in the world. However, in the history of China, the diversion of the lower Yellow River has brought great influence to human civilization. It is the most important birthplace of Chinese civilization, and China people call it "Mother River".
