When night falls, Yang Xiuyan and her mother stand outside their house waiting for his father to come back home. Yang lives in a small village named Badou Shangtaonao of Haiyuan County, Ningxia Hui Autonomous Region. Due to serious drought in consecutive years, the village is no longer a suitable residence for people. Yang's family also want to move to other places, but they can't afford it since Yang's father got ill and cost all savings. [Photo: Sina]
