Located in southeastern Yunnan, Xichou County had suffered from stony desertification, where 99.9 percent of the county is covered by mountainous areas, and 75.4 percent by Karst formations. The county was forced into poverty due to harsh natural conditions. In 1990, people here began to fight against the tough environment to change their life. They worked hard to reclaim the rocky lands, excavate roads in mountainous areas, afforest stony mountains and develop industries. After nearly 30 years of development, the whole county was lifted out of poverty in April this year. (Xinhua/Yang Zongyou)
