Mount Qingcheng and Dujiangyang

We happened to visit Mount Qingcheng and Dujiangyang, just outside of Chengdu, on a Chinese holiday. This meant both sites were very busy. However, the mountain was beautiful and Dujiangyang was extensive and impressive, the site of a 2300-year-old irrigation project that included dykes, dams and channels to get water through the mountain. Pretty amazing without modern machinery and techniques.
