Help me find information about the Yellow River.

The Yellow River is the second longest river in China. Originated in the Yuegu Zonglie Basin at the northern foot of Bayankala in Qinghai Plateau, it winds eastward, crosses the Loess Plateau and the Huanghuaihai Plain, and flows into the Bohai Sea. The total length of the main stream is 5,464 kilometers (1 Wanduoli), and the water level drop is 4,480 meters. The total basin area is 795,000 square kilometers (including 42,000 square kilometers of internal flow area).

According to the study of geological evolution history, the Yellow River is a relatively young river. In the late Early Pleistocene, 1 15000 years ago, there were only some unconnected lake basins in the basin, each of which formed an independent internal water system. Since then, with the uplift of the western plateau, rivers have been eroded and eroded. After the Middle Pleistocene of 654.38+0.05 million years, lakes and basins have been gradually connected, forming the embryonic form of the Yellow River system. It was not until the Late Pleistocene (654.38+ 10,000 years ago) that the Yellow River gradually evolved into a big river running up and down from the source to the estuary.
