Photo taken on May 17, 2017 shows Guoliang Village built on a cliff, Huixian, central China's Henan Province. 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.
