A total of 800 residents in Fulanyan Township of Changzhi, Shanxi province built a 10-kilometer road on a cliff on Taihang Mountain in 1968. They spent two years living on the mountain, drilling through five culverts with extremely primitive tools. The difference between the highest and the lowest culverts is about 200 meters, which means the road is quite bumpy. Today, the road is still unpaved, covered instead by sand and pebbles. It has a slope of more than 30 degrees, presenting a unique and magnificent view.
