Dunhuang is located at the western end of the Hexi Corridor in Gansu Province. We know that in the second century B.C. when Zhang Qian during the reign of Emperor Wudi of the Han Dynasty, was assigned to go to the Western Regions Central Plains culture and western culture were introduced into Dunhuang. Dunhuang thus became a major town on the Silk Road. Since then, Dunhuang has long played an important role in the cultural interaction of Eurasian countries and the cultural integration between the Central Plains and other ethnic groups. As Buddhism spread eastward to China Dunhuang was an important stop.
