Photo taken on Aug. 21, 2016 shows two Tibetan children playing under the Yuzhu Peak of the eastern part of the Kunlun Mountains in northwest China's Qinghai Province. The 6,178-meter-high Yuzhu Peak is the highest one of the Kunlun Mountains in Qinghai, and it is regarded as the best place for climbing beginners as its route requires less technique.
