@visit_china: Unforgettable places in China #40, Dujiangyan, Sichuan, China Dujiangyan is an ancient and remarkably sophisticated irrigation system located in Sichuan Province, China. Built around 256 BCE during the Warring States period by the engineer Li Bing and his son, Dujiangyan is a testament to early Chinese ingenuity in water management. Unlike traditional dams, Dujiangyan ingeniously diverts and controls the flow of the Min River without blocking it. Using natural topography and principles of fluid dynamics, it reduces flooding, prevents sediment buildup, and irrigates vast areas of farmland — benefits that continue even today, over 2,000 years later. This system not only showcases advanced hydrological engineering but also reflects the harmonious philosophy of working with nature rather than against it. Dujiangyan remains a UNESCO World Heritage Site and a symbol of sustainable infrastructure and ancient wisdom.
