is a wrnk cd the gasa(歌辭) that was composed by Jeong-chul(鄭撤). This work is contained in the anthology of his poetical works. But because of no comment in the postscript writen by Lee-seon(李選 ), there have been students who negated that was written by Jeong-chul. The reason was that Lee-seon`s postscript was misunderstanded for the anthology of Jeong-chul`s works. It is not so. Mr. Lee wrote it for his collection of Jeong-chul`s works without . So we must admit that is Jeong-chul`s work contained in his anthology. Jeong-chul wrote this work for Kim, Seong-own(金成遠). Mr. Kim lived free from worldly cares in Seong-san(星山). Mr. Jeong admired Mr. Kim for his living altitude and wrote this which was written in dialogue. This work was composed in three parts which are the visitor`s inquiry, the host`s answer and the visitor`s appreciation. Mr. Kim walked leisurely enjoying the mountajns and the waters in Seong-san, and related his thoughts and feelings. For his living so, the visitor take him for an unworldly man. So we do appreciate an esthetic sense in his enjoying the mountains and the waters.
