As the one of China's seven wall-mounted highways, the bottom wall road is comparable to Guo Liang. Perhaps the other six wall roads can be found in Baidu Encyclopedia, but the relevant information here is almost zero. This is the only way to the county. The entire road is built on a cliff and it is extremely thrilling. But it was because of its thrills that I was fascinated by it. When I crossed a deep tunnel, I met a beam of light, and that kind of flickering made people wonder where they were, only when the cars horn sounded. I can slow down and see the world again. According to the locals, from the village to the county town, they could only walk over the mountains and the mountains. In order to completely walk out of the village, they simply built a road on the cliff, which was only 1,500 meters long, but cost 14 Years old. Where from a distance, the side windows converge into a line to outline the direction of the tunnel, just like a winding dragon. The beauty of the wall is not only the road itself, but also the amazing picture under the cliff. Under the mountain is a beautiful village, surrounded by mountains, like a place of paradise, to the night, the moonlight and the starry sky will be very beautiful.
