The Dujiangyan Irrigation System consists of the headworks and a network of intricate channels. The headworks section includes the Fish Mouth, Flying Sand Weir, and Bottle-Neck Channel. These three engineering marvels embody the principles of harmony between nature and humanity, forming a unified whole that scientifically addresses issues like automatic water diversion, sediment discharge, and irrigation.
This system laid the enduring foundation of Dujiangyan, known as the "indestructible golden body."
For over two millennia, Dujiangyan has diverted the surging waters of the Min River into the vast Chengdu Plain, creating the "Land of Abundance" where water and drought do not trouble the inhabitants.
This nurtured a sense of ease and comfort among the people of this "Land of Plenty," fostering a feeling of security and beauty in the hearts of the Chinese.
