Introduction to Cave 11 to Cave 13: The three caves are a group of caves. A square pillar was cut out in the middle of Cave 11, and upper and lower niches were carved on each side. The upper part of the east wall has an inscription on the statue in the seventh year of Taihe in the Northern Wei Dynasty (AD 483), which is an important material for studying the history of the Yungang Grottoes. The front of the front room of Cave 12 is carved into three cave eaves that imitate wooden structures. Three Buddhist niches imitating wooden structures are also carved on the east and west walls. The top of the cave is carved with Ji Letian, holding instruments such as Paixiao, Payi, flute, and drum; Heavenly beings are the finest products in this cave.
