Horse riding introduction: The First Bay has the largest grassland in Sichuan Province, covering an area of nearly 30,000 square kilometers, consisting of meadow grassland and swamp. The grassland is flat, stretching as far as the eye can see, and sparsely populated. The Red Army's 25,000-mile Long March passed here many times, leaving behind many touching stories and revolutionary sites. The grassland in summer is the most beautiful time. Between heaven and earth, there are green grass, flowers, and fragrance, stretching as far as the eye can see.
