The Longyinxia Plank Road is located in the middle of Wulonggou, Houshan, Qingcheng, Chengdu. It was named after a river dragon hidden in the gorge in ancient times. The plank road is a dangerous road that must pass through the ancient West into the Jinchuan ramp. In ancient times, it was a rock pile for rock piles and is now reconstructed from reinforced concrete. The plank road is built in the middle of the mountain, close to the cliff, and the culvert is also vacant. It is a good place to watch the mountains and enjoy the summer.
