Grassland introduction: The Hulun Lake District has a warm and cool climate in summer, making it a good place to escape the heat. The water and sky of Hulun Lake are of the same color, with dense reeds, and there are also strange mountains and rocks such as "Lake Pillar", "Tiger's Mouth", and "Elephant Trunk Mountain". On the west bank of Hulun Lake, yurts, Lele carts, sheep, as well as cattle, horses, camels and shepherd dogs, together with the blue sky and white clouds, form wonderful landscape paintings.
