The longest river in China and Asia, and the third-longest in the world. It rises in the Kunlun Mountains, flows across the Tibetan Plateau, passes the cities of Chongqing, Wuhan, Nanjing, and Shanghai, and empties into the South China Sea. Its basin is China's granary and is home to nearly a third of Chinese citizens. The river is dammed by the Three Gorges Dam, the world's largest, which reduced flooding but displaced 1.5 million people and buried over 1,300 known archaeological sites.
