However, by the end of the Yuan Dynasty, with the decline of the Silk Road, the Mogao Grottoes also lost its former glory. It was not until the late Qing Dynasty that he became a Taoist priest to preside over this Buddhist holy land. 1900, the discovery of Buddhist scriptures in Dunhuang Mogao grottoes shocked the academic circles at home and abroad, and it provided the world with a new discipline-Dunhuang studies.

International thieves Stein, Peliott, Frenchman Werner and Americans robbed the Tibetan Sutra Cave. 、
