Before his literary debut, he had already published in 1960 his first collection Sarangeul yeonjuhaneun kkotnamu (사랑을 연주하는 꽃나무 The Flower Tree That Sings Love).
He is currently serving as the president of the Jiyonghoe (지용회) and the Association for Commemoration of Gong Cho, and he is a creative writing professor at JEI University.
By revealing the spirit of freedom based on humanism, he also displayed how sijo is a free verse form of a certain type, one that reaches the life's inner sides with emotions and rules.
However, his ultimate goal is to have a poetic spirit like a sinseon's (a Taoist hermit with mystical powers), that "listens with the eyes, sees with the nose, and talks with the ears."
His works are considered as literary instances where modern society and inner humanity were explored through the traditional form of sijo.
