Yǔwén Shàoyì 宇文紹奕 (Southern Sòng; CBDB id 17173) was a literatus of Chéngdū 成都. Few biographical details survive: the Sìkù editors note that they could find nothing of his career, but observe that a Yǔwén Shàojié 宇文紹節 served as Shūmì shǐ under Jiādìng (1208–1224), and they suggest the two may have been brothers, placing Shàoyì in the late 12th – early 13th century. His one notable surviving contribution is the Kǎo yì 考異 (Critical Apparatus) to 葉夢得’s Shílín yàn yǔ (KR3j0105) — a line-by-line bǐjì commentary correcting Yè’s institutional and chronological lapses. The Kǎo yì was lost in transmission and was reconstructed from the Yǒnglè dàdiǎn by the Sìkù editors, who appended it under the corresponding entries of the SKQS recension. It is one of the more substantial Sòng-on-Sòng bǐjì-critical works.
