[HIGHLIGHTS] Why did the Yungang Grottoes become the crystallization of the art of Sinicization of Buddhism?

Yungang Grottoes are located at the southern foot of Wuzhou Mountain and the north bank of the Shili River in the west of present-day Datong City, Shanxi. This cave temple excavated by the Northern Wei royal court gathered the most human, material and financial resources in the country at that time.

It represents the highest achievements of Buddhist art in the 5th and 6th centuries, and Dunhuang Mogao Grottoe and Luoyang Longmen Grotto are called the three major grottoes in China.
