Wáng Yǒng 王栐 (fl. early 13th c.; the surname-character is also written 柡), zì Shūyǒng 叔永, self-styled “Old Man Seeking the Will” (qiú zhì lǎo sǒu 求志老叟), was a Southern-Sòng official who claimed an ancestral seat in Jìnyáng 晉陽 but lived in Shānyīn 山陰 (modern Shàoxīng 紹興, Zhèjiāng). The Sìkù compilers establish from internal evidence in the Yānyì yímóu lù 燕翼詒謀錄 KR2e0013 that he was the nephew (yóuzǐ 猶子) of the Northern-to-Southern-Sòng transition statesman Wáng Lìn 王藺 (a man of Wúwéijūn 無爲軍 who took the directorship of the Bureau of Military Affairs in Shàoxīng 1 / 1131). He once served at Shānyáng 山陽 in Huáiběi but in what office is no longer recorded; his birth and death years are unknown. His one substantial work is the Yānyì yímóu lù, a 5-juǎn compilation of 162 early-Northern-Sòng institutional precedents drawn explicitly from the official Sòng documentary archive, completed around 1227 (Bǎoqìng 寶慶 era).
