Kim Jong-woon now Kim Jong Hoon(born August 24, 1984), better known by his stage name Yesung, is a Korean pop singer and occasional actor. He is one of the four lead vocalists of the super boy band Super Junior. He was once a radio host for his own radio program, M.I.R.A.C.L.E for You, which ended its broadcast in September 2007. His stage name Yesung (Hanja: 藝聲) is translated to "art-like voice" and is derived from the phrase "예술가의 성대", meaning "vocal chords of an artist."
On April 21, 2016 Yesung annouced that his mother changed his legal name to Kim Jong Hoon. She was worried 'Woon' would bring clouds to her life.
