In addition to paper and silk, traditional paintings have also been done on the walls, such as the Mogao Grottoes in Gansu Province. The Dunhuang Mogao Grottoes were built in the Northern Wei Dynasty (386–534 AD). It consists of more than 700 caves, of which 492 caves have murals on the walls, totalling more than 45,000 square meters. The murals are very broad in content, include Buddha statues, paradise, angels, important historical events and even donors. The painting styles in early cave received influence from India and the West. From the Tang Dynasty (618–906 CE), the murals began to reflect the unique Chinese painting style.
