Yungang Grottoes, Longmen Grottoes, Mogao Grottoes, and Maiji Mountain Grottoes are also known as the Four Great Grottoes in China. In July, I went to see the Mogao Grottoes and the Maiji Mountain Grottoes. I was deeply infected by art and painting art. In addition, I have visited some museums and temples in the past few years. I deeply felt Buddhism in ancient times. And the influence of the present world, more ancient craftsmen's unique craftsmanship and skillful craftsmanship deeply impressed. In September, I rushed to Shanxi and traveled to Shanxi. It happened that Yungang Grottoes were on the itinerary. I was fortunate to have the charm of three grottoes in 3 months and feel a lot.
