The road down the mountain is not blocked by the peaks, and the face is the dazzling sunshine and the wind of the plateau. Fortunately, the sun shines on the body, and you can feel a touch of warmth on the plateau. It is said that in the early years, a woman thirsty and drank water by the lake of Tojicuo. Just kneeling down, the child in the skin fell into the lake and drowned. She finally cleaned the empty mother of the 13 circles of the Shenshan for the confession of the son. Since then, people have taken the 13 circles as the standard of the mountain.
