Yanchi County of China's Ningxia restores environment, shakes off poverty

File photo taken on April in 2002 shows workers clear a road covered by sand in Jianerzhuang Township of Yanchi County, northwest China's Ningxia Hui Autonomous Region. Located on the southern edge of the Maowusu Desert, Yanchi County was once poverty-stricken and suffered from desertification. But after years of efforts, the environment there has been restored, and the county has also shaken off poverty. (Xinhua/Liu Quanlong)
