Rhyme is a genre of China's traditional poetry, which belongs to the category of modern poetry. Named for its strict metrical requirements. Metric poems originated from Shen Yue and other new-style poems that emphasized the antithesis of metrical poems in the Southern Dynasties, and were further developed and stereotyped by Shen Quanqi and Song Wenzhi in the early Tang Dynasty, which prevailed in the Tang and Song Dynasties. Rhyme has strict rules in word, rhyme, even tone and antithesis. Its common types are five-character poems and seven-character poems.
