Kui Xing (Chinese: 魁星; pinyin: kuí xīng; Wade–Giles: K'uei Hsing), originally called 奎星 (also kuí xīng), also known as 大魁夫子 "Great Master Kui" or 大魁星君 "Great Kui the Star Prince", is a character in Chinese mythology, the god of examinations, and an associate or servant of the god of literature, Wen Chang.
The name 'Kui Xing' literally means "Chief Star(s)", and anciently referred to the 'spoon' of the Big Dipper. The Chun Qiu Yun Dou Shu defines the ‘Kui Xing' as "The four stars in the first section of the dipper". The 'handle' was referred to as the 杓 shao, or ladle/spoon. Kui Xing's original name, 奎星, is the original name of the star in the Big Dipper located furthest from the 'handle' - Dubhe.
