In a literary work may reflect the socio-enviromental situations of the time. Lee Injae wrote "Sujingyeongheomsinbang" in early $20^{th}$ century, in a time when japanese colonization began and with which the influence of so called modern medicine, western medicine, were increasing. Though this trend was ever increasing the system for education and propagation was not enough and the practice of TKM was still predominant in public. This book reflect the concern of the author about this transitional time. He stat ing that TKM has a strong point in internal medicine while western medicine in external or surgical diseases tries to consolidate both medicines. This opinion is still valid today or at least serve as a reference as this problem still remains us to solve.
