Kweon Hyo-chin
Kweon Hyo-chin (Hangul: 권효진, Hanja:權孝珍, b. 27 March 1982) Korean female professional 8 dan. Her name is also spelled Kwon Hyojin.
Kweon Hyo-chin is the daughter of Kweon Kap-yong 9p (1957–2023) and his wife Park Ok-joo (b. 1958). She became a professional when she was 13. She was the first Korean female professional.
There is also a male professional 7p 22 years younger with the same name (both Hangul and Hanja), Kwon Hyo-jin (m). Because of her seniority and achievements, many sites treat her as the ‘default’ Kwon Hyo-jin unless otherwise stated. But KBA now designates her with the character for female (여) (yeo), while her male namesake has the male character (남) (nam).
