Tourists have fun at a scenic spot at the Kubuqi Desert in Erdos, north China's Inner Mongolia Autonomous Region, July 31, 2018. Kubuqi, the seventh largest desert in China, is a good example of China's success in alleviating desertification. About 6,460 square kilometers of the Kubuqi desert has been reclaimed in the last 30 years. (Xinhua/Zhang Shanchen) ?
