The 黄河, or Yellow River, is the second-longest river in China, stretching about 5,464 kilometers. It flows through nine provinces, starting from the 巴颜喀拉山 in Tibet and emptying into the Bohai Sea. The river is known for its yellow silt, which gives it its name, and has played a crucial role in Chinese agriculture and civilization. Historically, the 黄河 is often referred to as the "cradle of Chinese civilization" because it supported early settlements and farming. However, it is also notorious for its floods, which have caused significant damage throughout history. Efforts to control the river's flow have been ongoing for centuries.
