Starting from the eastern gate of Hanguguan Pass, the Old Path of Hangu stretches across the town and into the west. The only east-west passage through Guogou, Huangheyu, Langpigou to Chousang, it is 15km long. The valleys are 50-70m deep and 10m wide. In the narrow parts, it is only 2-3m wide and the gradient basin ranges from 40 degrees to 80 degrees. At the bottom, there is a road winding into the distance. On each side of the path, the precipitous cliffs and peaks rise abruptly high into the sky, the sight of which fills the people on the road with awe. |
