After the northern exile, he settled in Gwacheon (to the south of Seoul, where his birth father was buried) in a house he called Gwaji Chodang (瓜地草堂).
In the years following his death, his disciple Nam Byeong-gil (南秉吉) and others prepared and published collections of his letters (Wandang Cheokdok 阮堂尺牘) and of his poems (Damyeon Jaesigo 覃糧齋詩藁) in 1867; a collection of his other writings (Wandangjip 阮堂集) was published in 1868.
