Shishan Artillery Field: Located behind Shanhou Folk Culture Village, Shishan is the only tunnel-style howitzer field in existence. The tunnel is 508 meters long, with an average height of 4.6 meters and a width of 3.6 meters, which is quite spacious. The tunnel was converted into sightseeing in 2011. It is open to visit the internal combat readiness room, warehouse, artillery shell room, and artillery fort. Spiritual shouts and military training slogans are engraved on the wall, and the complete position and facilities are preserved, especially those who made military exploits during the 823 artillery battle. The 8-inch howitzer has a range of 17 kilometers and is extremely powerful, which shows the fierceness of the battle at that time.
