1. The gestation, birth and development of the Yellow River are controlled by geological processes in geological history. The tectonic movement caused by crustal changes is an external force, and the erosion, transportation and accumulation generated by itself under hydrogeological conditions are internal forces.
2. Historically, rivers in the lower Yellow River have changed from Haihe River in the north to Jianghuai River in the south. According to historical documents, the lower Yellow River burst 1500 times and changed its course more than 20 times.

The Yellow River is evolved from many lake basins. So far, there are only three lakes left, namely Zhaling Lake, Eling Lake in the source area and Dongping Lake in the lower reaches.
4. The Yellow River Basin starts from Bayan Kara in the west, reaches Yinshan Mountain in the north, Qinling Mountain in the south and Bohai Sea in the east. The inland potential in the basin is high in the west and low in the east, and the height difference is very large, forming three steps with high in the west and low in the east.
