Yuán-period 元 Shàngshū examination-essay specialist, with no preserved biographical record. Self-titled “Zōucì” 鄒次. The Sìkù tíyào on his Shū yì duànfǎ 書義斷法 (KR1b0033) is unable to identify his origin or detailed career: “bù zhī hé xǔ rén” 不知何許人 (“we do not know what manner of man he was”). His one work — the Shū yì duànfǎ in 6 juǎn — is a Yuán-period bookseller’s examination-preparation manual for the Shàngshū portion of the jīng yì 經義 examination essay, prefixed with the legend “kēchǎng bèi yòng” 科場備用 (“for use in the examination hall”). The work is roughly contemporaneous with 王充耘’s Shū yì jīn shì 書義矜式 (a more advanced model-essay collection); on the Sìkù compilers’ classification, Wáng’s work is the chéng mò 程墨 (“model writings”) of the genre, while Chén Yuèdào’s is the jiǎng zhāng 講章 (“lecture-text” or “study guide”). Together the two works mark the institutional emergence — within the post-1313 Yánȳòu examination orthodoxy — of the late-Imperial examination-essay study-manual industry, the “chuāi mó nǐ tí” 揣摩擬題 (“guessing-and-mimicking-the-set-questions”) culture that the Sìkù compilers explicitly trace to “shí zì cǐ làn shāng” 實自此濫觴 — “in fact, [the trend] takes its rise from these very works.”
