Some critics have described her work as “the moans of pain by someone who has not been loved” (Kim Hyeon) or as "perceiving a world full of lives that have lost their roots .

She attended high school in Seoul and studied German language and literature at Korea University.

She made her literary debut in 1979 when the journal Literature and Intelligence published five of her poems including “Love of This Age” (이 시대의 사랑).

Her 2010 poetry collection Sseulsseulhaeseo meonameon (쓸쓸해서 머나먼 Lonely and Faraway) marked a new beginning in her writing career.

Choi's first poetry collection Ishidaeui sarang (이 시대의 사랑 Love of This Age), published in 1981, investigates the underlying truth of all objects to find meaning in a life destroyed by society.

In her next works—Jeulgeoun ilgi (즐거운 일기 Merry Diary; 1984), Gieogui jip (기억의 집 House of Memory; 1989), and Nae mudeom, pureugo (내 무덤, 푸르고 My Tomb, Grave; 1993)—Choi continues to reject the world around her and refuses to compromise.
