Abstract: This paper proposes that in Song-Ming Neo-Confucianism of Wang Chuanshan，mind-nature ( xinxing) was really closely connected to political operation and can be effectively used to explain the historical reality. The first part of the article examines this point through Wang's study of the Confucian classis and historical commentaries. First the author examines Du Sishu Daquan Shuo，Sishu Xunyi，Zhouyi Waizhuan and other works to explain the connections between mind-nature and political practice as reflected in will (志)、capacity (量)、and knowledge (识) and the concept of“the method of the broad and far-reaching mind”. Secondly the article discusses that the learning of mindnature as reflected in those political practitioners，namely“miniter”，and dicusses the“Way of the Minister”. Additionally，the article explores Wang Chuanshan's thought on the connection of the learning of mind-nature and the “Way of the Minister”in his classical studies and historical commentary，and the close correlation to his unforgettable political experience in South Ming dynasty during Yong Li period.
