In 1992, She published her second volume of poetry Alone To A Distant House (혼자 가는 먼 집).

It can be said that distancing herself from her native tongue by living in a foreign environment is in itself the poet’s attempt to bring herself closer to the essence of the Korean language".

[8] Literary critic Lee Kwang ho noted the difference in the style of her post german migration work and her previous works saying while her pre germany works can be characterized as "a love poem combined with the rhythm and sensibilities of the South Gyeongsang Province and the loneliness and sadness that she faced as a woman", her work while in germany showed "her musings of lengthy periods that reflects her archaeological background".
