『Jang-jin-yo-pyeon』 is a medical book on acupuncture, published in 1894 by Song-gye. 『Jang-jin-yo-pyeon』 could not be seen in Korea, but it was published and made known in Japan by the disciples of the acupuncturist Yanagiya-Sorei, who took it to Japan during the Japanese colonial period. In 『Jang-jin-yo-pyeon』, the patient’s constitution was more important than the severity of the disease. In 『Jang-jin-yo-pyeon』, it seems to have been applied to the Eight Confluent Acupoints by classifying it according to weakness and strength, outside and inside, cold and heat, dry and wet. Referring to Kim Hong-kyung’s theory of Saam acupuncture, In 『Jang-jin-yo-pyeon』, it can be seen that he tried to control the human body with eight acupuncture points : (SI3-LU7) to treat strength and weakness, (TE5-PC6) to treat the outside and inside, (BL62-KI5) to treat cold and heat, and (GB15-SP4) to treat dryness and moisture. It can be seen that the intention was to tune the metabolism of the human body by limiting the application of only 8 types of acupoints placed in a relative relationship. This book is also one of the cases that proves that the acupuncture method of Joseon during the Japanese colonial period spread to Japan and contributed to the development of modern acupuncture. Through this case, it is presumed that the indigenous acupuncture methods of Joseon, which had been handed down for a long time, were cut off in the process of transition to the modern era, or that many traditional knowledge of Korean medicine was lost due to historical tragedies such as the Japanese colonial period or the Korean War. Efforts to discover and re-illuminate these traditional Korean acupuncture treatments so that they can be used in clinical practice are also thought to be a way to learn the old and learn the new.
