Hi, I found that definition : http://www.wordreference.com/koen/선수 But I simply was not convinced. I don't get it : his name is "Kang Ji-seung" In my case, it's a different context : the last name end in -seon-su. For example : the last name of a tv producer as his friend likes to call him : Kang seon-su : "강선수!" (or sometimes "강피디" for "Kang PD" which means Producer Kang.) Transalted in english, it means "Champ Kang" or "Super Kang" like "Big Mike", "Old Mike" or "Beauty Mike" ? Thank you.
