Dujiangyan: A Millennium Marvel of Water Management

The Dujiangyan Irrigation System is a masterpiece of ancient ingenuity, with its core lying in the ingenious Fish Mouth Levee. Standing like a fish's mouth at the heart of the river, it divides the Minjiang River into the Inner River for irrigation and the Outer River for flood discharge, automatically regulating water flow between dry and flood seasons. Utilizing the natural principle of bend circulation, it also efficiently redirects sediment, securing the Chengdu Plain’s reputation as the "Land of Abundance." Spanning the river, the Anlan Cable Bridge (also known as the Couples' Bridge) connects both banks and offers an exceptional vantage point to admire this hydraulic wonder.
