Bayan Kara disc rock painting

On the wall of the cave, archaeologists found rough paintings, including the rising sun, the moon, the unrecognizable stars and the earth … all of which are connected by lines of pea-sized points. Like these disks, these cave murals have a history of about 12000.

There are still two semi-cave tribes living in this cave area, called "Ham" and "Dropas". They look extremely strange. The average height of these thin and short tribesmen is only about 1.5 meters, and they are neither Han nor Tibetan. "Their ethnic background is a mystery." An expert said.
