Shen Quanqi and Song Wenzhi were both literati in the Tang Dynasty, and both made great contributions to poetry creation. In the development of five-character metrical poems, they further improved and standardized metrical poems. On the basis of Shen Quanqi, Song Zai, Xie Tiao and others, the metrical requirements of five words, four words and one word are put forward, which makes the form of five-word metrical poetry more fixed and unified.
