The purpose of this paper was to confirm the source of Shipsong called Yookchen or Yooksheen used in Myeongleehak and the meaning of Shipsong in major classics. It is to investigate the concept of Shipsong used in modern Myeongri, and to study in-depth the concept of Shipsong in a more advanced form, not just in family relationships. In reality, the concept of Yookchen was defined and the term Yookchen was first used in Yeonhaejapyeong. Most of the contents of the major classics, such as Yeonhaejapyeong, Sammyeontonghwe, and Japyeonjinjeong, were limited to setting only family concepts. Then, in 1963, Sajoojeongsul was published, which explained both family relations and the action of Shipsong. In particular, it is noteworthy that the scientific reputation written by Ki-seung Kim did not only explain the concept of Shipsong but also opened a new chapter to confirm human psychology and aptitude. In this study, I tried to find out the concept and tendency of Shipsong described in Kim Ki-seung's Science Myeongri in the major classics and how the concept changed. I hope this study will be of some help to the study of Myeongleehak in the future in terms of understanding and utilization of Shipsong.
