Wèi Shí 衞湜 (fl. 1205–1235), zì Zhèngshū 正叔, hào Lìzhāi 櫟齋, native of Wújùn 吳郡 (modern Sūzhōu, Jiāngsū). A late-Southern-Sòng official and classicist whose career advanced from the magistracy of Wǔjìn 武進 (where he held office in 1226 when he presented his Lǐjì jíshuō KR1d0057 to the throne and was promoted to Bìgé zhí 直秘閣) ultimately to Cháosǎn dàifu zhí Bǎomógé zhī Yuánzhōu 朝散大夫直寶謨閣知袁州. His one major work, the Lǐjì jíshuō in 160 juan, is the most comprehensive Sòng-period commentary on the Lǐjì, drawing on 144 named schools and serving as the unique transmission-channel for some 49 otherwise-lost Sòng Lǐjì commentators (per Zhū Yízūn’s Jīngyì kǎo). The work was begun in the Kāixǐ–Jiādìng period, took thirty-and-more years across drafting, presentation, printing (Shàodìng xīnmǎo 1231 by Zhào Shànxiāng at the Jiāngdōng Cáoyuàn), and revision. Precise birth-and-death dates undocumented; CBDB id not confidently identified.
