Vehicles run on the cliff corridor in Guoliang Village in Huixian, central China's Henan Province, May 17, 2017. The Guoliang cliff corridor is a 1,250-meter-long road built along the cliff. The construction of this miraculous road lasted five years from 1972 to 1977, and was built purely by hand by villagers of Guoliang Village. Thanks to this road, villagers here cast off poverty.
