Hong Su-yun (born February 9, 1987) is a boxer[1] from Seoul, South Korea whose foray into boxing escalated into a series of championship-fighting performances. Eventually, she developed her jabs and counter punches to become a well-rounded fighter and who opts to keep a low profile inside the ring to catch her opponents with their guard down and deploy a strong right uppercut. She became more serious about boxing in 2010, when she signed a contract with her boxing label to become a professional.[2]
Hong Su-yun turned professional in 2010 and compiled a record of 7-0 before facing and defeating Thai boxer Teeraporn Pannimit, to win the WBO Mini flyweight title.[3] [4]
