Introduction to "Handprint" rock paintings: On a smooth stone wall on the north side of the ravine, there is a simple peach-shaped human face carved with a figure of a hand on the left and right below. One of the hands is connected with half an arm. Slim and soft, it is considered to be a representation of maternal power; under the other hand there is a cow kneeling towards the female hand, which is considered to be a conquered tribe.
