Day 4: "Autumn" at Dujiangyan Irrigation System :)

Since we are in Mt Qingcheng, we stopped by at the oldest and only surviving no-dam irrigation system in the world, Dujiangyan Irrigation System. This irrigation system is important in draining off flood and to irrigating farms, and providing water resources for more than 50 cities in the province. What's mind blowing is it was built in 256BC and naturally a UNESCO Cultural Heritage Site. *.*

We won't supposed to be here for so long and should be on the road before nitefall...But...well.... :))) Pingle, here we come. :D
