The Red Plateau Riganqiao Everglades is an important part of the world's largest plateau wetland-Zoergai Wetland Reserve. The soil is between3300--3500 meters above sea level and the soil is the potential marsh soil and peat marsh soil. In the late autumn, I walked along the grassland road. I couldn’t see the vast grassland on the side. The color was yellow and red. I thought this was the origin of Hongyuan. When I saw the sun dry Qiao Everglades, I realized that Hongyuan was because the Red Army left every inch of this vast marshland. In the footprints, friends who know the modern history of China know that there was a heroic team here to launch a tragic and heroic epic battle with nature, that is, the Long March of the Red Army of Workers and Peasants in 1935. This vast open, connected sky, marsh, muddy marsh, the weather is fickle, even in the middle of summer, sometimes cold currents roll, sometimes rainstorms, winds, hail, wind and snow can be seen at any time. For the Red Army, who had long been in the war between the north and the south, the clothing had been reduced to a point that could not be reduced, the thin clothes were in tatters, and the cold cold at night was bone-drenched, so they had to squeeze together in threes and twos, sucking a little warmth from each other. More serious is the lack of food, only to dig wild vegetables, boil belts, drink cold water, do everything to satisfy the hunger. The vast grass is so cruel and ruthless, I don't know how many Red Army soldiers have lost their lives. Now it has built the red original day dry Qiao red army cultural tourism area, its scope includes color land, wheat depression, wache three townships.
