Dujiangyan is an ancient irrigation system located in Dujiangyan City, Sichuan Province. Built in 256 BC by Li Bing, the governor of Shu Prefecture during the Qin Dynasty, it is the world's oldest non-dam irrigation system still in use. A UNESCO World Heritage Site, it ingeniously controls water flow without a dam, using the Yuzui (Fish Mouth) levee, Feishayan (Flying Sand Weir), and Baopingkou (Bottle-Neck Channel). It has irrigated the Chengdu Plain for over 2,200 years, earning Sichuan its reputation as the 'Land of Abundance.'
