Dunhuang
Dunhuang is located at the westernmost end of Hexi Corridor at the intersection of Gansu Province, Qinghai Province, and Xinjiang Uyghur Autonomous Region. In ancient times, it was an important gateway from the Central Plains to the Western Regions and an important node of the Silk Road. It was also one of the first cities to open to the outside world. The convergence and assimilation of the ancient Chinese civilization and ancient Indian, Greek, and Persian civilizations gave rise to unique Dunhuang culture and fostered the Silk Road spirit characterized by openness and inclusiveness.
As a critical node of the Silk Road, Dunhuang easily drew in envoys, military commanders and soldiers, merchants, and monks from all over the world. Silk, porcelain, jewelry, gems, camels, horses, and food, among other commodities, were conveniently traded in Dunhuang, making it a key transit point for ancient East-West trade. Many religions, ethnicities, and cultures came together in Dunhuang. Ethnic minorities in the northwest mingled and blended there, and foreign cultures from Rome, India, and Arab merged there. Historical records declared, "the coexistence of the Han people and the minorities made it no less important than a cosmopolitan city" and celebrated the pluralistic and harmonious Dunhuang culture and the splendid (now) World Heritage Mogao Caves.
