Dujiangyan, located in Sichuan Province, China, is a renowned ancient irrigation system and a UNESCO World Heritage Site. Built around 256 BCE during the Qin Dynasty by governor Li Bing and his son, this engineering marvel diverts the Min River to prevent flooding while irrigating the fertile Chengdu Plain. Unlike dams, Dujiangyan uses natural topography to regulate water flow, showcasing advanced hydraulic techniques that still function today. The site also features cultural landmarks like the Erwang Temple, dedicated to Li Bing, and the picturesque Fulong Pavilion. Surrounded by lush scenery near the Qingcheng Mountains, Dujiangyan blends historical significance with natural beauty, attracting tourists and engineers alike. Its sustainable design remains a testament to ancient Chinese ingenuity, benefiting agriculture for over 2,000 years.
