Chi are turret-like protruding sections placed at regular intervals along a fortress from which defenders could protect the fortress  and drive back an approaching enemy. There are ten such structures at Hwaseong. The term chi, which literally means "a pheasant," was applied to these structures because pheasants are adept at hiding in grass and remaining watchful. Seoichi is located between Seoporu (Western Cannon Fort) and Seojangdae (Western Command Post).
