In the Xiaojiake area near Alar City in northwest China's Xinjiang Uygur Autonomous Region, three rivers meet to form the source of China's longest inland river, the Tarim River. During the lingering dry season, the gentle flow gradually increases. From above, jade-like water meanders through sunlit riverbeds of golden sand. White salt flats lie between sand and water, creating a rare, breathtaking scene of yellow, emerald and white along the Tarim River.
