Suungyo (수운교 / 水雲敎), usually anglicized as Suunism, is a religion in South Korea, founded by a schism from Cheondoism in 1923.
The Suunist flag, known as the Geungulgi (궁을기 / 弓乙旗), is yellow with the Suunist emblem, known as the Geunguljang (궁을장 / 弓乙章), in black at the centre. The two crescents represent the human body (몸), and the ring represents the human character (성품).
