The purpose of this paper is to examine the editions of ‘Jeokcheonsu’, the best Myoungri Classic in name and reality, that was featuring dozens of annotations and interpretations from the Qing Dynasty to the Republic of China, and modern times. The original author of ‘Jeokcheonsu’ was Gyeongdo of the Song Dynasty, firstly annotated by Yugi of the late Yuan Dynasty to Early Ming Dynasty, and Im Cheolcho of the Qing Dynasty annotated again. However, several observations in the original text suggest that the author's period of writing is postulated since the middle of the Ming Dynasty, and if the book is not likely to belong to the Song Dynasty, the author is also unlikely to be Gyeongdo of the Song Dynasty. Besides, if you look at the statements of Jin Soam and Jeong Jiwoon, who published the early editions of ‘Jeokcheonsu’, there are many negative opinions about the usual author recognition. In this study, we conducted a comparative analysis of the four existing editions of ‘Jeokcheonsu’, ‘Jeokcheonsu-Jibyo’ edited and published by Jin Soam, ‘Myeongri Suji Jeokcheonsu’ revised by Jeong Jiwoon, ‘Jeokcheonsu-Cheonmi’ annotated by Im Cheolcho, and ’Jeokcheonsu-Jingui’ edited and published by Seo Rako. It is hoped that this study will help us understand ‘Jeokcheonsu’ more deeply and help us with related research, such as comparative studies of annotations in the future.
