황하강, or the Yellow River, is the second-longest river in China, stretching about 5,464 kilometers. It flows through nine provinces and is known for its distinctive yellow color, which comes from the silt it carries. The river is vital for agriculture and has been a crucial water source for millions of people throughout history. The Yellow River is often referred to as the "cradle of Chinese civilization" because many ancient cultures developed along its banks. It has played a significant role in shaping the history and culture of China, providing fertile land for farming and serving as a major transportation route.
