The starting point of Yayigou is located in the north of Lulang, extending from south to northwest, with a height of about 20 kilometers from the altitude of 3,400 meters above sea level at the starting point to more than 4,100 meters at the end point. Except for the local herders, few people in the outside world know about the existence of Yayigou.

On the last day of August, early in the morning, a few friends and I entered Yayigou.

We set off from the entrance of Yayi Ditch and went up the Yai River. As soon as you enter the mouth of the ditch, between the strange trees and rocks in the valley, a river water gushes out. This is the Yai River, which runs through the Yai ditch. The Yai River is fast, and the current seems to be frozen at first glance because of its fast speed. Up close, the river looked like a snowdrift, like an ice cube, and from a distance, it looked like a silver chain set in a huge piece of jasper.

Walking into Yayigou, a leafy primeval forest appeared on the slopes on both sides, and at the foot of the forest, white flowers bloomed, and the fragrance of flowers came to the face. All the way forward in the fragrance of flowers, the colors of the flowers are becoming more and more abundant, the white is dazzling, the red flowers are like blood flames, and the blue is a little delicate, and the primeval forest seems to grow in the sea of flowers.

In autumn, it is as if we are walking in spring.

Walking through the sea of flowers, it is a fairytale forest. The ground of the forest, on the stones, and even on the branches of the trees were covered with thick moss. A few rays of sunlight shone through the gaps in the branches and leaves, shining on the ground, and the moss glowed with a layer of gold. Walking on the golden moss, it is soft and soft, giving people a feeling of being in the clouds. A thin stream of water twisted through the moss of the forest, and the murmur was accompanied by the occasional birdsong or two. People just want to stop, in this world that doesn't seem to be reality, stand quietly as a tree, let the fresh air, melt themselves.

At noon, we walked through the primeval forest and arrived at a pasture. Surrounded by mountains is a large gentle slope with a few small wooden houses on the top, and the slope is a lush green grass, and the grass is scattered with a few yaks that seem to be careless about everything. Around the meadow are clusters of low bushes, the leaves of which have turned red, and against the boundless green background, they resemble colorful glows perched on the grass. At the end of the meadow, there is the clear Yayi River. Here, the Yai River flows gently, so clear that you can see the pebbles at the bottom of the river, and the small fish are playing freely. On the surface of the river, there is a wooden bridge. A few friends who walked with me walked on the wooden bridge and lay down and didn't leave, saying that they wanted to lie on the bridge and watch the sky of the plateau rise and fall.

Lying on the wooden bridge, there is a gentle flowing water under the bridge, one side of the bridge is a grassland perched with colorful clouds, and the other side is a mountain decorated with strange stones, wild flowers, and strange trees. Looking at the clouds in the sky, they are slowly covering us. It's like we're lying in a painting. Lying on the wooden bridge, the scenery of Yayi Ditch is vivid. The river that gushes out, the path that smells of flowers, the golden moss, the silver whiskers of the old trees, the steep mountains, the strange stones and trees......

But Yayigou is Yayigou, it is not named after people, its existence is only for it. Only by walking through Yayi Ditch will you know that the world has such a beauty, and you will know that the world has such a wonder.
