My sister explained the relationship between Beiqi and the grottoes, and the development of other grottoes. From time to time, let us observe the details here. Many of them are still very Indian Buddhist expressions. We look up at the mystery of the coffin storage on the roof of the Great Buddha Cave and admire the strength of the imperial grottoes. We are also overwhelmed by the beauty of all kinds of stone carvings. There is too much gossip here. There are hardly any Buddha statues with heads in Beixiangtang Hall. Some grottoes are almost a stone chamber of light. They are very ruined. Many stone carvings were repaired in the Ming and Qing Dynasties. Their artistic style and characteristics are indeed original. There is a certain distance. Walking along the rows of grottoes, the last scripture-carving cave is one of the few Grottoes here. The inscriptions on the wall are very dim. This should be the grotto where the American scholars introduced in the previous books have carried out three-dimensional restoration. The shape of one Buddha, two disciples and four Bodhisattvas here is also complete, but there is still no head. Digital technology restores its American studies. These people are the owners of these Buddha heads, but these circumstances explain that my sister did not even know, and we began to hesitate whether it was wrong to remember.
