im not sure what it exactly means but a korean person once told me that you should introduce yourself like this is korean.
(i am going to spell it like it should sound)
"on-yo iss say yo, chun dun (your name) E me dah, mono pa-gos-sa-me-da."
then kindly bow your head.
i believe it means hello, my name is ___, how are you." ( i think but im not completely sure. im about 85% positive it is though.
hope this helps. =)
