Discover the world’s most ingenious ancient water management system that has been controlling floods and irrigating farmlands for over 2,000 years without a single dam. The Dujiangyan Irrigation System, built around 256 BCE by the visionary engineer Li Bing and his son, represents one of humanity’s greatest triumphs in harmonious environmental engineering—transforming the turbulent Minjiang River into the lifeblood of Sichuan’s fertile Chengdu Plain.
Unlike typical tourist attractions that offer static historical displays, Dujiangyan presents a living, breathing engineering marvel that continues to function exactly as designed over two millennia ago. For international visitors seeking authentic Chinese cultural experiences beyond the usual temple tours, this UNESCO World Heritage site offers profound insights into ancient Chinese philosophy of working with nature rather than against it.
The Engineering Genius That Created “Heaven’s Storehouse”
The Dujiangyan system solved one of ancient China’s most pressing challenges: how to control the devastating floods of the Minjiang River while providing reliable irrigation for agriculture. Li Bing’s revolutionary solution was elegantly simple yet brilliantly complex—instead of building a dam that would block the river’s natural flow, he created a self-regulating system that divides, controls, and redirects water using three ingenious components.
The Three Pillars of Ancient Innovation
Yuzui (Fish Mouth Levee): This cleverly designed artificial island splits the Minjiang into two channels—the Outer River (Waijiang) for flood discharge and the Inner River (Neijiang) for irrigation. The pointed shape resembles a fish’s mouth, hence its poetic name. During flood season, 60% of water flows to the outer channel, while in dry season, 60% flows to the inner channel for irrigation, automatically adjusting without human intervention.
Feishayan (Flying Sand Weir): Perhaps the most ingenious component, this spillway acts as both a flood outlet and a natural sediment removal system. When water levels rise during floods, excess water “flies” over the weir, carrying sediment away from the irrigation channels. This self-cleaning mechanism has kept the system operational for over two thousand years without major dredging.
Baopingkou (Bottle Neck Channel): This narrow artificial gorge cut through Mount Yulei controls the volume of water entering the irrigation network. Its bottle-neck shape naturally regulates flow—during high water, the constriction prevents too much water from entering the irrigation channels, while during low water, it ensures sufficient flow for farming needs.
Cultural Significance: Where Philosophy Meets Engineering
Dujiangyan embodies the core Chinese philosophical principle of “harmony between heaven, earth, and humanity” (天人合一). Rather than conquering nature through brute force, Li Bing’s design works with the river’s natural behavior, redirecting its power for human benefit while preserving its ecological integrity.
The system reflects Taoist principles of wu wei (无为)—achieving maximum results through minimal intervention. This philosophy permeates Chinese culture and is beautifully demonstrated in Dujiangyan’s elegant simplicity. The nearby Mount Qingcheng, just 15 kilometers away, is actually considered the birthplace of Taoism, making this region the perfect place to understand how ancient Chinese thought influenced practical problem-solving.
Daytime Exploration: Walking Through Living History
What to Expect During Your Visit
The scenic area covers approximately 200 hectares with well-maintained walkways connecting all major viewing points. The standard route takes you across the famous Anlan Suspension Bridge (安澜桥), offering spectacular aerial views of the water division at Fish Mouth Levee. From there, you’ll walk along embankments to observe each engineering component up close.
Key Viewing Points:
- Erwang Temple (二王庙): Dedicated to Li Bing and his son, providing historical context
- Anlan Bridge: 240-meter suspension bridge offering panoramic river views
- Yuzui Observation Platform: Close-up views of the water division in action
- Feishayan Overlook: Watch flood control and sediment management
- Baopingkou Viewing Area: See the precision-cut intake channel
Best Visiting Strategy
Morning (8:00-12:00): Start at Erwang Temple for historical context, cross Anlan Bridge for panoramic views, explore the Fish Mouth Levee area, and observe water flow dynamics at Flying Sand Weir.
Afternoon (13:00-16:00): Visit Baopingkou for detailed engineering examination, explore Lidui Park for river ecosystem understanding, and conclude at the visitor center for comprehensive exhibits.
Evening Magic: Nanqiao (South Bridge) and the “Blue Tears” Phenomenon
As daylight fades, Dujiangyan transforms into something entirely different—and arguably even more magical. The Nanqiao (South Bridge) becomes the centerpiece of an enchanting evening experience that combines natural beauty with modern illumination technology.
The “Blue Tears” Spectacle
When darkness falls, the South Bridge area comes alive with carefully positioned blue LED lighting that creates one of Sichuan’s most Instagram-worthy phenomena. The flowing waters of the Minjiang River, illuminated by this ethereal blue glow, shimmer and dance like liquid sapphires, earning the poetic nickname “Blue Tears” (蓝眼泪).
This isn’t merely a tourist gimmick—the lighting design thoughtfully enhances the natural movement of the water, creating patterns that shift and flow with the current. The reflection of the blue lights on the water’s surface creates an almost supernatural atmosphere, where the boundary between river and sky seems to dissolve into flowing light.
📸 Perfect Photo Spot: Position yourself on the South Bridge around sunset (7:30-8:30 PM depending on season) to capture the transition from golden hour to blue illumination. Long exposure shots create stunning light trails following the water’s movement.
Photography Tips for Blue Tears
- Best timing: 30 minutes after sunset for optimal contrast
- Camera settings: Use a tripod for long exposures (2-4 seconds) to capture light trails
- Composition: Include the bridge structure for context and depth
- Weather: Slightly misty evenings enhance the ethereal effect
Culinary Heaven: Nanqiao Food Street Experience
Beneath and surrounding the South Bridge lies one of Sichuan’s most vibrant culinary destinations—a sprawling food street complex that represents the authentic flavors of the region far from tourist traps. This isn’t just a collection of restaurants; it’s a living showcase of Sichuan’s incredible culinary diversity.
A Gastronomic Journey Through Sichuan

Cultural Etiquette and Respect
Dujiangyan remains an active site where local communities depend on the irrigation system for their livelihoods. Visitors should respect ongoing maintenance work and avoid interfering with water management operations. The temples within the complex are active religious sites—dress modestly and observe quietly during any ceremonies.
Beyond Engineering: Understanding Regional Impact
The system’s success created the economic foundation for Sichuan’s development as one of China’s most prosperous regions. The reliable water supply enabled intensive agriculture, supporting larger populations and freeing human resources for arts, crafts, and commerce. This prosperity contributed to Sichuan’s rich cultural traditions, from cuisine to opera to craftsmanship.
Understanding Dujiangyan helps international visitors grasp why Sichuan Province holds such cultural significance in China and why Chengdu evolved into a major urban center. The phrase “When Dujiangyan benefits, Sichuan benefits” (都江堰利，川西利) reflects this fundamental relationship.
Modern Relevance and Global Lessons
As climate change intensifies weather extremes globally, Dujiangyan’s sustainable approach to water management offers valuable lessons. The system’s ability to handle both floods and droughts without environmental degradation demonstrates principles that modern engineers are rediscovering. Several contemporary flood control projects worldwide have adopted elements of Dujiangyan’s design philosophy.
