Cháng Qú 常璩 (c. 291–361), zì Dàojiāng 道將, of Jiāngyuán 江原 (modern Chóngzhōu 崇州 in west Sìchuān). A senior figure under the short-lived ChéngHàn 成漢 dynasty (Lǐshì Shǔ Hàn 李氏蜀漢, 304–347), where he served as Sǎnqí chángshì 散騎常侍 to its last ruler Lǐ Shì 李勢, he was one of the principal court officials who in Yǒnghé 永和 3 (347) urged Lǐ Shì to surrender to the Eastern-Jìn general Huán Wēn 桓溫 (an act for which the Sìkù editors compare him to Qiáo Zhōu 譙周, who likewise advised Liú Shàn to capitulate to Wèi). After the fall of ChéngHàn he was relocated to Jiànkāng (modern Nánjīng), where he completed both the Hànzhī shū 漢之書 (also titled ShǔLǐ shū 蜀李書), an internal court history of the ChéngHàn dynasty in ten juàn (lost), and his masterpiece, the Huáyáng Guózhì 華陽國志 KR2i0003 in twelve juàn — the earliest surviving regional history of southwest China and the first complete dìfāngzhì in Chinese literature. The Suízhì placed both works in its Bàshǐ 霸史 category. Cháng Qú came from the powerful Jiāngyuán Cháng 江原常 lineage of the early-Jìn Shǔ scholar-gentry, and the partial Chángshì shìnǚzhì later reconstructed by Zhāng Jiāyǔn for the Huáyáng Guózhì covers his own kinswomen. The floruit in the catalog meta is given as 265–316; the more precise dates 291–361 follow Wilkinson and the standard scholarly consensus and are adopted here.
