The development of Zhu Xi's system of learning relied on the eight clauses and subclauses of the Great Learning as guiding principles. His interpretation of the two ”Nan” collections of poems in The Book of Songs followed this context, and it was established as the ideal course that King Wen followed to achieve benevolent-rule politics. This article examines Zhu Xi's interpretation of every poem in the two ”Nan” in the context of the second half of the Great Learning's clauses and subclauses-”First cultivate yourself, then bring order to your family, after which govern your people well and then rule the world,” to analyze the norm that each represented. By comparing the poems in the two ”Nan,” one can conclude that Zhu Xi deliberately applied the process of ”practice self cultivation, govern one's family, run the country well, and conquer the world” to his commentaries of the two ”Nan,” so as to establish his interpretation that King Wen is the exemplary basis for moralizing and teaching.
