Two books written during the Period of the Three Kingdoms once held sway as containing the ”knowledge of the country.” Both works expounded upon Gu-Liang-ism in the Wei Kingdom during the Sanguo (Three Kingdoms era). One work was by Mi-Hsin explained the Gu-Liang and another book, also on the Gu-Liang by Fan-Ning, both works enjoyed great popularity. But it was the work byMi-Hsin that later overtook the one by Fan-Ning in popularity during the Nan-Chao-Chi dynasty during the time of Yung-Ming (483-493 A.D.). As a result theMi-Hsin School prevailed in importance for Gu-Liang-ism for more than a century during the six dynasties of Wei-Jin. However, the books written by Mi-Hsin, Chun-Chiu Gu-Liang Explanations (Chun-Chiu Gu-Liang Chuan-Chu), Essentials of Chun-Chiu (Chun-Chiu Shuo-Yao) and Chun- Chiu Han-Yi, have long been lost. The only books explaining Mi-Hsin's Chun-Chiu Gu-Liang Chuan-Chu are those written during the Ch'ing Dynasty by Wang Mo, Huang Shi and Ma Guo-Han. Among these three Ch'ing-era writers, Ma, Guo-Han is said to have created the best study. As a result this paper takes as its foundation Ma's 35, and 1 that Ma doesn't collected, explanations that address four areas, namely the ideas of the Gu-Liang, the interpretation of historic systems, the writing concepts of the classics, and the explanations and pronunciation of words and sentences. This study uses this method in an effort to recover the content and arguments made by Mi-Hsin by piecing together the fragments of this highly treasured work to better profile the essence of Gu-Liang-ism.
