I wrote a story about him in my blog in 2010, when he won his Eddie Herr tournament (what a cute little boy he was!)
Friend of mine, who lives and works in Korea found and translated for me some Korean articles about him (not translated, maybe, by briefly retold)
His father is journalist, they found he is deaf when he was 100 days old, he can hear some very loud noises, like train's hooter, but it's like a whisper for him.
His father's biggest dream too see his son in Korean Olympic squad. They had some difficulties with money at this time, but I think it's not a problem now, because Lee is sponsored by one of Korean corporation, I don't remember it's name, this contracn was signed two years ago AFAIR.
