When Li Bing and his son split Mount Yulei in 256 BC, they likely never imagined their creation would still be irrigating millions of acres of Chengdu's farmland today!
Dujiangyan's ancient genius stuns modern engineers:
▸ Yuzui Bifurcation Dam: Nature's original "water circuit board" dividing flow 60-40
▸ Feishayan Weir: A sand-flushing wonder using centrifugal force
▸ Baopingkou Channel: The world's first damless water diversion system
UNESCO declares: "The most ecological hydraulic marvel in human history!" No concrete, no electricity—just mountain topography and water flow achieving:
✓ Flood control ✓ Irrigation ✓ Navigation ✓ Ecological balance
Standing on Anlan Cable Bridge watching the Min River divide, you'll understand true "Daoist harmony with nature"—this damless system encodes deeper Eastern philosophy than Yu the Great's flood control.
