Qiáo Zhōu 譙周 (201–270), zì Yǔnnán 允南, was the most influential classicist and historian of the ShǔHàn 蜀漢 state, a native of Xīchōng 西充 (Ānhàn 安漢 county, present-day Sìchuān). His biography is Sānguó zhì 三國志 j. 42; the dates 201–270 follow Wilkinson, Chinese History: A New Manual (some Chinese reference works give 199–270, but the Sānguó zhì notice and his ages at named events support 201). A student of the Sìchuān classicist Dù Qióng 杜瓊, he in turn taught Chén Shòu 陳壽 — the eventual compiler of the Sānguó zhì itself — and Lǐ Xī 李興. Under the Shǔ regime he held the office of Diǎnxué cóngshì 典學從事 (Director of Imperial Scholarship) and later Imperial Secretary of the Heir Apparent (太子家令).
He is principally remembered today for two acts and three works. The acts: his sponsorship of the surrender memorial that brought Shǔ to terms with Wèi in 263 — for which he was condemned by some later moralists and praised by others as having spared Sìchuān a futile war; and his polemical Chóu guó lùn 仇國論 (“On the Adversary State”), composed during the late Shǔ period against Jiǎng Wǎn 蔣琬’s northward campaigns. The works: the Gǔshǐ kǎo 古史考 (Investigation of Ancient History) — usually regarded as the earliest extensive critical commentary on the Shǐjì (extant only in jíyì form); the Fǎxùn 法訓 (Standards and Instructions) — a zǐ-house treatise of moral admonition, also extant only in fragments; and the Wǔ jīng rán fǒu lùn 五經然否論 (a discussion of the five classics). In the Kanripo corpus he appears as the attributed author of KR3a0123 Qiáozǐ fǎxùn. CBDB has no entry for him.
