Introduction to the Tangbula Prairie: Tangbula is the collective name for the grassland landscape of the Kashgar River Gorge in Nilek County. It is named after a ravine 105 kilometers southeast of the county because of its ridge on the east side of the ravine. Several huge rocks resemble jade seals, hence the name Tangbula, which means big seal in Kazakh. The grassland is full of green grass, blooming mountain flowers, snow-capped spruce trees, and high mountains and white clouds. Every step of the way creates a scene that is poetic and picturesque, with the charm of Swiss scenery.
