The Yellow River, with a total length of about 5,464 kilometers and a drainage area of about 795,000 square kilometers, is the second longest river in China and the fifth longest river in the world. It originated from Kariqu at the northern foot of Bayankala Mountains in Qinghai Province, showing a "few" shape. It flows through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong provinces and finally flows into the Bohai Sea. 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 highest sediment concentration in the world. However, in the history of China, the Yellow River and its coastal basins have brought great influence to human civilization, and it is one of the most important cradles of the Chinese nation.
