The wall-mounted highway is very shocking, and Kunshan Tunnel is even more amazing. It is said that they are all cut by hand. How much manpower and perseverance will it take to cut them out? And it's all over the cliff. It's spectacular and dangerous. It's more interesting than Xiyagou. You can walk through Kunshan Tunnel to Wangmangling Scenic Spot. The Xiyagou Wall-hanging Highway is in Wangmangling, but these two places are just the junction of Henan and Shanxi, so tickets are required on both sides.
