When I came to the valley of waves, I saw red stones like mudslides, which were flowing in circles, in circles, in circles, in curves and in curves to the gully. This stone resembles a sandstone, and the weathering is very serious. Walking on top, you will slip the red sand attached to your skin without paying attention. Follow the red stones along the ditch and go down, and you will see large and flat stone walls in the wide area, which are red from top to bottom and are basically the same color. In the narrow, red stones appear to be flowing water, like red mud, flowing toward the bottom of the ditch. On the long mouth opposite the village ditch, the terrain here is relatively flat, those layers of stone like a large number of red cloths covered on the ground after being soaked, layer by layer, roll, plate under the sunset, abnormal red; A red water from loess slowly flows down low-lying areas. Along the trail of red stones, the eyes are suddenly wide, a river valley that looks like a canyon is in front. The red stones all solidified here in flowing water, like a red ice hanging, like a frozen magma, with the trench bottom of a small river and the distant windmills that rotate on the top of the green vegetation constitute a beautiful real picture.
