나의 살던 고향은 (My hometown that I lived in)

 꽃피는 산골 (Is a flower blooming mountainous place)

복숭아꽃 살구꽃 아기진달래 (With peach blossum flowers, apricot flowers and baby azaleas )

울긋불긋 꽃대궐 차리인 동네 (Various palace of flowers in the neighborhood)

그 속에서 놀던 때가 그립습니다 (I long for the time I played in that place)

꽃동리 새동리나의 옛 고향 (My old neighborhood was a flower neighborhood and bird neighborhood)

파란 들 남쪽에서 바람이 불면 (When the harsh blue wind blows from the south)

냇가의 수양버들 춤주는 동리 (The weeping williow of the creek dancing in the neighborhood)

그 속에서 놀던 때가 그립습니다 (I long for the time I played in that place)
