Photo taken on Sept 22, 2015 shows a plant on a sand dune in the Badain Jaran Desert in Araxan of North China's Inner Mongolia autonomous region. The Badian Jaran Desert, the second largest desert in China, has an area of 47,000 square km and is sparsely populated. It is famous for having the tallest stationary sand dunes in China. Some dunes reach a height of 500 meters. But it also features spring-fed lakes that lie between the dunes. [Photo/Xinhua]
