🧠 Explanation:
- The Yellow River, also known as Huang He, is the second-longest river in China and the sixth-longest in the world.
- It originates in the Bayan Har Mountains in western China and flows across nine provinces before emptying into the Bohai Sea.
- The river is called the "cradle of Chinese civilization" because many ancient Chinese cultures flourished along its basin.
- Its name comes from the yellow-colored silt (loess) it carries, which gives the water a distinctive yellowish tint.
