Historical Overview
Qin Dynasty Origins: Constructed c. 256 BCE to tame flood-prone Minjiang River and transform Sichuan into a “Land of Plenty.”
Tang to Qing Dynasties: Enhanced with stone dikes and spillways; survived earthquakes, including the 2008 Wenchuan quake.
1949–Present: Modernized with monitoring systems while preserving ancient structures; recognized globally for ecological design.
Cultural Significance: Honored as a “National Treasure” and pilgrimage site for engineers and historians.
Structural Layout
The system comprises three core components:Yuzui (Fish Mouth) Split: A rock-weir dike dividing the river into inner (irrigated) and outer (flood-relief) channels.
Feishayan (Flying Sand Weir): An overflow spillway that expels silt and excess water during floods.
Baopingkou (Bottle-Neck Channel): A narrow engineered gorge regulating water flow to farmland.
Secondary features include Erwang Temple (honoring Li Bing) and Anlan Suspension Bridge (a 5th-century bamboo-and-rope crossing rebuilt in stone).
Major Attractions
Fish Mouth Levee: Observe the river’s bifurcation and silt-separation process.
Feishayan Spillway: Witness floodwater cascading over the weir during rainy seasons (June–September).
Baopingkou: Hike the steep stone channel flanked by guardian deity statues.
Erwang Temple: Explore shrines to Li Bing and his son, with Qing Dynasty murals and a 4.5-ton “Iron Ox” flood gauge.
Anlan Bridge: Cross the Minjiang River on China’s oldest surviving suspension bridge (5th century CE).
Lidui Park: A riverside garden with a 3D model of the system and a teahouse overlooking the irrigation network.

Best Time & Tips
Visit Early: Arrive by 8 AM to avoid crowds (opens 8:00 AM); Feishayan’s spillway is most dramatic in summer.
Avoid Weekends: Tour groups flood the site; weekdays are quieter.
Pack: Waterproof shoes (mist from spillways), sunscreen, and a hat.
Bring cash for temple offerings and street snacks (try doujiang soy milk and zongzi rice dumplings).
Hire a guide (¥150–200) to decode engineering details.
Pro Tip: Combine with a trip to Mount Qingcheng (20 mins by taxi), a Taoist mountain retreat!
Why is Dujiangyan’s "Fish Mouth" shaped like a fish?
The "Fish Mouth" (a triangular dyke) is shaped like a fish to reduce water resistance, splitting the Minjiang River into inner and outer streams
How to tour Dujiangyan following the "irrigation principles" theme to understand its engineering logic?
Start at the Fish Mouth to learn about water diversion. Move to the Flying Sand Weir to observe sediment removal. Visit the Precious Bottle Neck to see water control in action. End at Erwang Temple to study Li Bing’s management rules—each stop connects to the next, revealing the system’s "smart design."
What unique rituals are held during the annual "Water Release Festival"?
On April 5th, locals dress as ancient officials to reenact Li Bing’s "water release" ceremony: they remove a stone marker (indicating the dredging depth) and let water flow into farmland.
What’s the easiest way to get from Dujiangyan to Qingcheng Mountain after your visit?
Take bus No. 101 from "Dujiangyan Scenic Area" to "Qingcheng Mountain Front Gate" (30 minutes, ¥2). It’s direct and runs every 15 minutes, perfect for combining both UNESCO sites in one day.
What "irrigation-themed" souvenirs can you take home?
Mini replicas of the Fish Mouth or Precious Bottle Neck, with explanations of their functions. Bamboo baskets (like those used for dredging) woven with patterns of the river. Postcards with photos of the system in different seasons, paired with Li Bing’s quotes.
