 Nanseolheon's works are noted primarily for their broad range of subject matter, which is attributed in part to the drastic emotional shift evoked by her marriage.The inclusion of two "kasa" written in "hangul" in the collection is one of scholarly contention, as her authorship is in doubt.Composition in hangul was considered unworthy of expressing higher thinking of Confucian ideals, and "literary" composition in Korea was almost entirely composed in "hanmun".
