During the Agrarian Revolution, the Red Army passed through the Liuyang River area, and the rich man fled to the city in fright. The fat and thin rich brothers were afraid that the villagers would catch up, so after crossing the river, they burned the bridge on the Liuyang River. After the Red Army entered the village, they helped the villagers build a new bridge. In order to thank the Red Army, the villagers erected a sign on the new bridge with three characters "Red Army Bridge" engraved on it.
