The Collection of Ancient Poems, edited by Zhang Zhixiang of the Ming Dynasty, included poems written during the period of Han, Wei and Six dynasties. Its completed time was before Zhang's another compilation of The Collection of Tang Poems. The whole book was divided into 44 parts according to the content of those poetic works, so that it was often mistaken as a classified book. In fact, its distinct editorial way just followed a previous compiling style of some collections of poems and essays, which facilitated later generations to study a certain kind of poems.
