Five-character Poetry: A genre of China's traditional poetry, which belongs to the category of modern poetry. It originated in the period of Qi Yongming in the Southern Dynasties, and its prototype is Shen Yue's new poem which pays attention to rhythm and duality. It was basically shaped by Shen Quanqi and Song in the early Tang Dynasty and matured in the prosperous Tang Dynasty. The whole poem consists of eight sentences, each with five words. There are two basic forms: ascending and descending, and the two couplets must be in dialogue. Representative works include Li Bai's "Seeing Friends Off" and Du Fu's "Spring Hope".
