The Black Tortoise or Black Turtle (Chinese: trad. 玄龜; simpl. 玄龟 Xuán Guī) is one of the Four Symbols of the Chinese constellations. Despite its English name, it is usually depicted as a turtle entwined together with a snake. Further, in East Asia, it is not called after either animal but is instead known as the "Black Warrior" under various local pronunciations. It is known as Xuan Wu (or sometimes Xuan Gui) in Chinese, Hyeonmu in Korean, Genbu in Japanese and Huyền Vũ in Vietnamese. It represents the north and the winter season.
