Cáo Dàozhèn 曹道振, Yánpíng jìnshì (Yánpíng = modern Nánpíng 南平, Fújiàn) of Zhìzhèng 3 (1343, late Yuán). Editor of the standard 17-juǎn recension of Luó Cóngyàn 羅從彥 羅從彥’s Yùzhāng wénjí KR4d0182. According to Cáo’s own yuánxù (preserved in the Sìkù tíyào): the prefectural-resident Xǔ Yuántáng 許源堂 had earlier cut a 5-juǎn version of Luó’s surviving collection; Cáo recently obtained a manuscript of 13 juǎn + 3 juǎn fùlù + 1 juǎn wàijí + 1 juǎn niánpǔ (= 18 juǎn total) from a fellow-townsman, Wú Shàozōng 吳紹宗. The Yuán recension circulated until lost; the Míng Chénghuà 8 (1472) reprint by Zhāng Tài 張泰 (with a Jiājìng jiǎyín = 1554 colophon by Xiè Luán 謝鸞) is the basis for all later prints, including the WYG.
