The total length of the main stream is 5,464 kilometers, second only to the Yangtze River, making it the second longest river in China. Because the middle section of the river flows through the Loess Plateau in China, it carries a lot of silt, so it is also known as the river with the most sand in the world. However, in Chinese history, the diversion of the lower reaches of the Yellow River has had a huge impact on human civilization. It is the main birthplace of Chinese civilization, and the Chinese call it the "Mother River."
