Southern-Sòng cí-writer (fl. late twelfth century), zì Zhèngbó 正伯, hào Shūzhōu 書舟 (after the boat-shaped study-pavilion in his Méishān 眉山 garden), of Méishān in Shǔ; the maternal cousin (zhōngbiǎo 中表) of Sū Shì 蘇軾 from the same town. No precise life-dates are recorded; Wáng Chèng 王稱’s preface to his Shūzhōu cí KR4j0009 is dated Shàoxī jiǎyín (1194), placing his active years across the late Chúnxī and Shàoxī periods (c. 1175–1200). Chéng’s principal extant work is a body of c. 156 cí, preserved in one juǎn in the Máo Jìn 毛晉 cutting and reprinted in the Sìkù. He was recommended for office by Shàngshū Yóu Mào 尤袤, who held that his prose surpassed his shī and cí; the prose and shī are now lost. Yáng Shèn 楊慎’s Cí pǐn singles out Kù xiāngsī, Sìdài hǎo, and Zhé qiū yīng as his best pieces; he is conventionally read as a transitional figure between the SūHuáng Sòng xiǎolìng manner he inherited through family and the longer, denser Southern-Sòng manner that culminates in Jiāng Kuí 姜夔.
