Zhāng Guāngzǔ 張光祖 (fl. Dàdé 1297–1310), zì Shàoxiān 紹先; native of Xiāngguó 襄國 (Xíngtái 邢台, modern Héběi). In Dàdé xīnchǒu (1301) appointed Quánzhōu tuīguān (Investigator at Quánzhōu, Fújiàn). His one surviving work is the Yán xíng guī jiàn 言行龜鑑 (KR3j0184) in 8 juàn, an early-Yuán expansion of Zhào Shànliáo’s late-Sòng Zì jǐng biān, drawing on additional sources (Diǎn xíng lù, Hòu dé lù, Shàn shàn lù, Míng chén yán xíng lù) and on famous-minister stele inscriptions. Prefaced by Chén Pǔ 陳普 (Shítáng xiānshēng, 1303) and Xióng Hé 熊禾 (Wùxuān xiānshēng, 1304), both eminent Sòng-loyalist Confucians whose endorsement gives the work substantial moral weight. The catalog meta records lifedates 1285–1346 which appear erroneous (this would make him tuīguān at age 16); no biography of him appears in the Yuán shǐ or in the gazetteers; the Sìkù editors note that his beginning and end “cannot be investigated.”
