Dunhuang was in China's territory long ago. Since the construction of the Mogao Grottoes, the changes of art and Buddhist culture have been recorded. After the emergence of the Silk Road, it was even more exposed to the culture of both China and the West. It not only recorded many cultural aspects but also recorded the prosperity of the Silk Road at the time. However, for various reasons, the collection of Mogao Grottoes was destroyed by man-made or natural disasters. In order to preserve the cultural relics preserved in the Mogao Grottoes, we have chosen various media to preserve these relics.
