Murals at Cave IK1
According to geographic features, functions and conception of locals, the total 105 caves are divided into three groups: Area I, II and III, which respectively contain 29, 35 and 41 caves. The three caves in Area I are best preserved, in which clay sculptures of nimbuses, pedestals and cha-cha could be seen. These caves are mainly Buddha halls, and some of them are meditation halls and houses for monks. Grottoes in Area II are all seriously damaged due to collapses of cliffs, which only keeps parts of the structures. Some murals and clay sculptures of nimbuses could be seen from the lower front slope, showing that they once served for Buddha halls. Unfortunately at present they are inaccessible for archaeologists. Grottoes in Area III are well preserved. Most of them are living houses and many have stone walls right in the front.
