The Korean folk song "Platycodon Ballad" is also known as "Doraji".

"Daolaji" is a kind of wild vegetable that Korean people like to eat, namely Platycodon grandiflorum. This Korean folk song was originally produced in Gangwon Province and later spread throughout the Korean Peninsula. The lyrics are different and the tune is smooth and smooth. Legend has it that Dhalaki is the name of a girl. When the landowner robbed her to pay off his debt, her lover angrily hacked the landowner to death, and was imprisoned. The girl died of grief, and before she died, she asked to be buried on the mountain road that the young man must pass to chop wood. In the spring of the next year, a small purple flower bloomed on the grave. People called it "Doragi" (Korean for "Platycodon") flower, and composed a song to praise the girl's innocent love.

Every spring, North Korean women go to the mountains to dig platycodon in groups. Since they are not allowed to go out according to custom, this song also expresses a happy mood when they are collecting platycodon outside. The music of "Platycodon Ballad" is brisk and clear, vividly portraying the hard-working and lively image of Korean girls.
