The Vermilion bird is one of the Four Symbols of the Chinese constellations. According to Wu Xing, the Taoist five-elemental system, it represents the fire-element, the direction south, and the season summer correspondingly. Thus it is sometimes called the Vermilion bird of the South (南方朱雀, Nán Fāng Zhū Què). It is known as Zhuque in Chinese, Suzaku in Japanese, Jujak in Korean and Chu Tước in Vietnamese. It is often mistaken for the Fenghuang due to similarities in appearance, but the two are different creatures. The Fenghuang (similar to the phoenix in western mythologies) are legendary ruler of birds associated with the Chinese Empress in the same way the dragon is associated with the Emperor, while the Vermilion Bird is a mythological spirit creature of the Chinese constellations.
