Southern-Sòng cí-writer (fl. Chúnxī–Jiātài, c. 1180–1210); zì Jìwēng 濟翁, hào Xīqiáo 西樵, of Lúlíng 廬陵 (Jiāngxī). Close literary friend of Xīn Qìjí 辛棄疾: the Jiàxuān cí preserves a Shuǐdiào gētóu “matching Yáng Jìwēng’s rhyme” and two Dié liàn huā annotated Hé Yáng Jìwēng yùn. His name has been a chronic source of textual confusion: Chén Zhènsūn 陳振孫’s Shūlù jiětí gives the correct Yáng Yánzhèng, zì Jìwēng; Mǎ Duānlín 馬端臨’s Wénxiàn tōngkǎo mis-cuts as Yáng Yán, zì Zhǐ Jìwēng; Máo Jìn 毛晉’s Liùshí jiā cí perpetuated the error; Lì È 厲鶚’s Sòng shī jìshì settled the matter using parallel evidence from the Wǔlín jiùshì and Quán fāng bèi zǔ. His sole surviving work is the Xīqiáo yǔyè KR4j0041 in one juǎn, preserving 37 cí in the Máo Jìn cutting, of which 6 are matching-Xīn-Qì-jí. The collection is conventionally read as the principal witness to the XīnQìjí literary circle of Shàngráo and Yángzhōu in the late twelfth century.
