Wú Shīdào 吳師道 (1283–1344), zì Zhèngchuán 正傳, was a Yuán-period scholar from Lánxī 蘭谿 (in modern Zhèjiāng). He took the jìnshì in Zhìzhì 1 (1321), at the relatively late age of 38, and rose through provincial offices to Erudite of the National University (guózǐ bóshì 國子博士) at the central court. After retiring he was recalled in his last years as Director of the Bureau of Ceremonies (lǐbù lángzhōng 禮部郎中). His record is in the “Confucian Scholars” treatise of the Yuánshǐ. He is known above all as a textual critic and annotator: his Zhànguó cè jiàozhù 戰國策校注 KR2e0005 is the most rigorous of the Sòng–Yuán annotated recensions of the Zhànguó cè and consolidates the three-stratum 高誘 / 姚宏 / 鮑彪 commentary tradition into a single critical apparatus. He also produced studies on the Yìjīng, on the Lǎozǐ, and a literary collection (Wú Zhèngchuán wénjí 吳正傳文集). The catalog meta entry for the Zhànguó cè jiàozhù misclassifies him as “Sòng” (a common error reflecting the date-of-the-base-text convention), but he was unambiguously a Yuán scholar.
