This is an Aobao formation. When nomads were moving across the grasslands, they would use them for navigation. Nowadays, they have become somewhat of a prayer platform. Here is my guide, Rose, bowing and praying to the Aobao three times, before continuing to place another rock on the formation. As she began to walk around the Aobao three times, she would make a wish. Her strong belief that wishes comes true this way was enchanting.
There are 5 coloured prayer flags seen here: Red for the sun, blue for the sky, green for the grass, yellow for the earth and white for the clouds.
