Wáng Sù 王肅 (195–256), zì Zǐyōng 子雍, was a leading classicist of the CáoWèi 曹魏 court. A native of Tánchéng 郯城 in Dōnghǎi 東海 commandery (modern southern Shāndōng), he was the son of Wáng Lǎng 王朗 and the father-in-law of Sīmǎ Zhāo 司馬昭, making him the maternal grandfather of the future Jìn 晉 emperor Wǔdì 武帝 (Sīmǎ Yán 司馬炎). He rose through the Wèi bureaucracy to Palace Counsellor (中領軍) and Cavalier Attendant-in-Ordinary (散騎常侍); his official biography is Sānguó zhì 三國志 j. 13. He was the most determined classical opponent of the HànWèi authority Zhèng Xuán 鄭玄 (127–200), composing rival commentaries on virtually the entire classical corpus and crystallising his polemic in the Shèngzhèng lùn 聖證論. The CBDB sqlite carries multiple homonyms named 王肅, none with confident birth/death years on the Wèi figure; the dates 195–256 are taken from his Sānguó zhì biography.
The Kanripo corpus carries his commentaries and recensions on the Kǒngzǐ jiāyǔ 孔子家語 (KR3a0001) and Kǒng cóngzǐ contexts, the reconstructed zǐ-house treatises KR3a0121 Wángshǐ xīnshū 王氏新書 and KR3a0129 Wángzǐ zhènglùn 王子正論 (both surviving only as Qing-era jíyì), and his name surfaces frequently in classical commentary literature throughout KR1.
