Seven-character poetry is a genre of China's traditional poetry, which belongs to the category of modern poetry.
New-style poetry originated in the period of Qi Yongming in the Southern Dynasties, paying attention to rhythm and duality, and was further developed and stereotyped in the Shen and Song Dynasties in the early Tang Dynasty, and matured in the hands of Du Fu in the prosperous Tang Dynasty.
Seven-character verse is strict, which requires the unity of words in the poem. It consists of eight sentences, and each sentence has seven words. Every two sentences are a couplet, and * * * is a quadruple, which is divided into first couplet, parallel couplet, neck couplet and tail couplet. The two couplets in the middle demand antithesis. Representative works include the Yellow Crane Tower in Cui Hao, Du Fu's Ascending, and Li Shangyin's Stabilizing Tower.
