Song of the Yellow Bird
Song of the Yellow Bird is the oldest known Korean lyric poetry and was written by Yuri of Goguryeo in 17 BCE It was written lamenting the loss of one of his wives who left his household following a quarrel with another of his wives. While Yuri of Goguryeo was away hunting, his second wife, Chihui, who was Han Chinese, was scolded by his first wife, Hwa hui: “How can you be so rude even though you are only a concubine?" Chihui left the household, never to return. Missing her greatly, Yuri of Goguryeo wrote this song.
A translation into Hanja of Song of the Yellow Bird is recorded in the history book of Goryeo Dynasty, Samguk Sagi.
