English language audio devices are available to inform the self guided tourists of how, during the Warring States period (475-221), Li Bing, Governor of the Shu Kingdom Prefecture, tamed the consistenly flood prone Minjiang by building the water diversion, and control project known as the Dujiang Weir.

Using a hill seperated from the Yuling mountain by hand, and the employemnt of innovative engineering practices which used super-heating to split rock, Li Bing divided the river in two. By directing one part East, to prevent flooding of the Southern plains, and the other Northwards, for field irrigation, he boosted the production of farm produce, and in-turn, regional economic development. Two other features, the Feisha Weir, which discharges flood waters, removes debris, and regulates water quality, and the Baopingkou (Treassure Vase Mouth), a narrow 'inner river' canal which controls the volume of water entering the ever dividing irrigation canals, combine to minimize the flood threat, and carry water to the thirsty food producing plains.

The wide, and covered 500 meter long Anluan Bridge, known as "the Husband and Wife Bridge" with ornately decorated ceilings covering the center, and both side thoroughfares, can bustle with human activity. People gazing out enraptured by the rushing waters passing from under the bridge, or posing for selfies, with the beautifully coloured ceilings, or tapping feet to the beat of the bridge's musical performers,or being photographed with monkey costumed bridge entertainers dressed in silk Kung Fu apparel. Yes, the bridge can be a colourfull, and entertaining respite from sun or drizzle, or just simply a marvelous structure to be enjoyed by all.

Employing quite different construction methods but as equally well engineered, and equally as much fun is the rope and plank type bridge crosing to the Erwang temple, and temple grounds which house green tiled roof buildings along with delicate gardens built as a memorial to Li Bing and his son.

Plan on spending the best part of day to be be able to visit all, or at least most of Dujiang Weirs many attractions, including the seven sided, eight cornered Taoist temple of Fuliong, and still leave time to just sit back and marvel at the absolute cleverness of it all.
