Chén Yìzēng 陳繹曾 (ca. 1287–1351), zì Bófū 伯敷. The Yuán shǐ 元史 attaches him to the Rúxué zhuàn 儒學傳 appendix and gives him as a man of Chǔzhōu 處州 (modern Lìshuǐ 麗水, Zhèjiāng); the Wúxìng xùzhì 吳興續志 also records his name as a Wúxìng 吳興 (Húzhōu) figure. The conventional resolution — which the Sìkù editors accept — is that his ancestral home was Kuòcāng 括蒼 (i.e. Chǔzhōu) but that he was resident at Tiáoshuǐ 苕水 (i.e. Wúxìng). In the Zhìshùn 至順 era (1330–1333) he rose to the position of Guózǐjiàn zhùjiào 國子監助教 (assistant instructor in the Imperial Academy). He studied under Dài Biǎoyuán 戴表元 (the well-known late-Sòng / early-Yuán gǔwén master) and was a personal friend of Chén Lǚ 陳旅 — a lineage of teachers and friends that places him in the central early-Yuán gǔwén tradition. His extant writings on prose-craft include the Wénquán 文筌 (8 juǎn, with Shī xiǎo pǔ 詩小譜 appended in 2 juǎn; Yuán Máshā 麻沙 reprint), the Kējǔ tiānjiē 科舉天階 (lost), the Gǔjīn wén jīnshì 古今文矜式 (2 juǎn; lost), and the Wén shuō 文說 (KR4i0046) — the last surviving only in Yǒnglè dàdiǎn reconstruction. The Sìkù editors observe that the KR4i catalog gives him as 宋 (“Sòng”), but he is unambiguously an early-Yuán figure: his official career under the Yuán, his teacher Dài Biǎoyuán (d. 1310), and his composition of the Wén shuō in response to the 1313 re-establishment of the kējǔ under Renzong all place him securely in the Yuán. CBDB id 439190 gives 1287–1351.
