Introduction to Fengshan Terrace: Fengshan Terrace is located on the south side of Wenfeng Pagoda, right on the ridge of Fengshan Mountain. It is built of red gravel and is 40 meters long, 18 meters wide and 5 meters high. There is a city gate opening in the middle. There is a plaque with the word "Yanzhen" in the northeast and the word "Fengshan" in the southwest. Fengshan Tower and Wenfeng Tower were built at the same time. In the early days of the Anti-Japanese War, the Red Army guerrillas from eight southern provinces gathered in Yansi, and Fengshan Terrace was used as a military parade point. In April 1998, it was listed as an Anhui Provincial Cultural Relics Protection Unit in the name of the former site where the Red Army guerrillas were concentrated in eight southern provinces.
