In the middle of the east wall is a scene of Buddha\'s life story. To its south side is a fifty-one-headed thousand-armed and thousand-eyed Avalokitesvara and to its north, a eleven-headed, thousand armed and thousand-eyed Avalokitesvara. The fifty-one heads are arranged into several layers, one above another, just like a pagoda. The thousand hands extend from the back of Avalokitesvara like the rays radiated from a dot into every direction. Each hands has a eye in the palm and holds more than 40 kinds of attributes, including the scenes of forging, brewing, husking rice, farming, boats, temples, music instruments, dragon, and kylin. It is the only one in Dunhuang caves.
