Photo taken on June 4, 2016 shows a river merged by two streams of different colors inside the Wakhan Corridor in northwest China's Xinjiang Uygur Autonomous Region. With an average altitude of over 4,500 meters above the sea level, Wakhan Corridor, a narrow strip of land connecting Afghanistan and China, used to be a trade route used by travellers going to and from China to central Asia since antiquity. The section inside China is about 80 kilometers long on the Pamirs Plateau. This remote, vast yet mysterious land is now inhabited by nomads of Tajik and Kirgiz ethnic groups. They move twice a year with all their livestock to chase richer pastures along the valleys, and these early summer days mark their busiest time of the year. (Photo/Xinhua)
