During the Japanese Invasion of Korea in 1592, General Gwon Yul was surrounded by Dokseong Fortress in Suwon, and the Japanese army waited for the fortress to lack water
However, when General Kwon Yul washed the horse with rice, the Japanese army mistook it for washing the horse with water and judged that there was enough water in Toxic Fortress
a story that quickly lifted the siege
