Slide: Keeper of Grottoes in Xinjiang

For 17 years, Rahman Amut has been the guardian of the 1,600-year-old grottoes, important Buddhist cultural relics on the ancient Silk Road. Kizilgahr in Uygur means "a girl to say." Amut has become very familiar with the 64 grottoes here, and he can detect each crack and other tiny little changes in them, Xinhua reported. [Photo/Xinhua]
