Born into an aristocrat's family, he engaged himself in studies in his early years.

He passed a literature exam in 1444 and began working as a government official whose job was to select reserve bureaucrats.

He played a key role in compiling "Kyonggukdaejon", code of the Feudal Joson Dynasty, in 1470 and compiled "Tongmunson" (133 vols.), a collection of poems, in 1478

He wrote "Korean Geography" (50 vols.) in 1481 and compiled "Tonginsihwa", a collection of critiques, which dealt with the poems well known until the 15th Century.

In the collection, he was critical of the poems with no idea and cautioned against me-tooism in creating poems.
