Photo taken on Aug. 24, 2011 shows a winding road on a mountain in Qibainong Township in Dahua Yao Autonomous County, south China's Guangxi Zhuang Autonomous Region. Due to harsh stony desertification, people from dozens of counties and districts in Guangxi had long been poverty stricken. Recent years, a comprehensive environmental control program has been carried out to control stony desertification for poverty alleviation purposes. (Xinhua/Zhang Ailin)
