Chén Yǒurén 陳友仁 (early Yuán, fl. late 13th – early 14th c.; CBDB id 47745 has fl. earliest 1355 — but the dating in the KR1d0013 Sìkù tíyào and his own preface point to an earlier floruit). Zì Jūnfù 君復. Native of Wúxīng 吳興 (modern Húzhōu, Zhèjiāng), a Sòng loyalist (yímín 遺民) who refused to serve the Yuán.
The editor of KR1d0013 Zhōulǐ jíshuō 周禮集說 — a Sòng-period anonymous Zhōulǐ anthology that he received from his friend Shěn Zézhèng 沈則正 of Zhā 霅 (Húzhōu) and re-edited, supplementing missing glosses with material from the Jiǎ Gōngyàn and Wáng Ānshí commentaries and adding discussions from senior contemporaries on points where the original anthology had left issues unresolved. He also appended Yú Tíngchūn’s KR1d0006 Zhōulǐ fùgǔ biān to the recension.
His preface is dated using the cyclical year bǐngzǐ + 9 (i.e., 1284) rather than a Yuán reign-title, on the model of Táo Qián’s 陶潜 (Táo Yuānmíng) practice of dating his Jìn-period writings without reference to the LiúSòng calendar — a Sòng-loyalist gesture. The Sìkù tíyào points out that Táo’s practice was in fact pre-dynastic-change, but Chén Yǒurén’s chosen anchor (bǐngzǐ = 1276, the year Lín’ān fell) and abstention from Yuán reign-titles are unmistakable Sòng-loyalist signalling.
CBDB id 47745. The fl. 1355 in CBDB is likely the date of a homonymous late-Yuán figure or a misregistration; Chén Yǒurén the editor of Zhōulǐ jíshuō must be active well before — his bǐngzǐ + 9 = 1284 preface is the secure reference point.
