Yuán-period 元 Shàngshū commentator, native of Jí’ān 吉安 (modern Jiāngxī) — same Lúlíng / Jí’ān region as the much-earlier KR1b0019 author Chén Jīng 陳經. The Sìkù tíyào on the Dúshū guǎnjiàn (KR1b0032) records his zì as Gēngyě 耕野; the parallel tíyào on the Shū yì jīn shì (KR1b0060) records his zì as Yǔgēng 與耕. Both are likely valid (one may be his zì and the other his biézì 別字 / alternate name; alternatively one may be a transcriptional slip). Birth year 1304 (CBDB id 101150); death year unrecorded but post-1333 (his jìnshì).
Career: in the Yuántǒng era he took the jìnshì examination using the Shàngshū as his classical specialization (yǐ Shū yì dēng jìnshì èr jiǎ 以書義登進士二甲), placing in the second tier. The Dúshū guǎnjiàn tíyào dates the jìnshì to Yuántǒng 1 / 1333 and assigns him the office of Tóngzhī Yǒngxīnzhōu shì 同知永新州事 (Vice-Magistrate of Yǒngxīnzhōu, Jiāngxī); the Shū yì jīn shì tíyào dates the jìnshì to Yuántǒng 2 / 1334 (元統甲戌) and assigns him the office of Yǒngzhōu tóngzhī 永州同知. Either Yǒngxīnzhōu (Jiāngxī) or Yǒngzhōu (modern Húnán) is possible; the Yuántǒng era began in 1333 and the 甲戌 year is 1334, so the two tíyào differ by one year. Subsequently he resigned the office to care for his mother; thereafter lived as a private teacher and author.
He has three surviving works in the Sìkù: (1) the Dúshū guǎnjiàn 讀書管見 (KR1b0032) in 2 juǎn — his critical Shàngshū commentary that disagrees with Cài Shěn (KR1b0017) on a striking number of substantive points (despite his having sat the post-1313 Cài-orthodox examination); (2) the Shū yì jīn shì 書義矜式 (KR1b0060) in 6 juǎn — a manual of model examination essays on selected Shàngshū passages, in the jīng yì chéng shì 經義程式 (“examination-essay-format”) genre that the Sìkù compilers identify as the institutional precursor of the MíngQīng bā gǔ wén 八股文 (“eight-legged essay”); and (3) the Sì shū jīng yí guàn tōng 四書經疑貫通 — separately in the Sìkù, treating the Sì shū portion of the same examination canon.
That the same author produced both a critical commentary disputing the canonical Cài zhuàn and a model-essay manual within the Cài-orthodox examination system is itself an instructive case-study: late-Yuán scholars could simultaneously occupy the orthodox examination space (in the Jīn shì) and the critical scholarship space (in the Guǎn jiàn) without institutional contradiction.
