Due to harsh environmental conditions, Xia'an has long been a less developed village in Hebei. From 2016 to 2017, a relocation program had been carried out to build houses in better-off places for poverty alleviation purposes. Many villagers have moved into their new houses since the completion of the program in July 2017. (Xinhua/Yang Shiyao)
