What has truly endured at Dujiangyan for over two thousand years is not a static arrangement of unchanging stones, but rather a way of understanding and harnessing power. It harnesses the river's own energy while leaving room for the river itself; it establishes engineering boundaries while remaining open to maintenance, modification, and renewal by successive generations.

What has truly endured at Dujiangyan for over two millennia is not a static arrangement of unchanging stones, but a dynamic system capable of continuous adjustment, refinement, and maintenance. It harnesses the river’s power while leaving space for the river itself; it establishes engineering boundaries while embracing ongoing upkeep; it preserves core principles while allowing for the constant evolution of materials, standards, and technologies. Perhaps the legacy Dujiangyan

Dujiangyan has endured for over two millennia not because of a static ancient engineering design, but thanks to a "living system" comprising water diversion, sediment discharge, flow regulation, and continuous maintenance. From the Fish Mouth, Flying Sand Weir, and Precious Bottle Neck to the annual maintenance protocols and "Iron Ox" benchmarks—and extending to modern reservoirs, sluice gates, and digital dispatch systems—the project has constantly adapted and evolved. Ultim

More than two thousand years ago, instead of damming the Min River with a single barrier, Li Bing utilized the Fish Mouth, the Flying Sand Weir, and the Precious Bottle Neck to allow the water flow, riverbed, and terrain to work together in regulating the river. While today’s Dujiangyan has integrated modern reservoirs, sluice gates, and digital monitoring systems, its core philosophy endures: rather than subduing the forces of nature, the aim is to understand them, make room
