Zhèng Pǔ 鄭樸 was a late-Míng scholar of Suìzhōu 遂州 (modern Suìníng 遂寧 in Sìchuān) active in the Wànlì 萬曆 era. He is known principally as the compiler of the six-juǎn recension of the Yáng Zǐyún jí 揚子雲集 (KR4b0001), assembled by combining Yáng Xióng’s Tài xuán, Fǎ yán, Fāng yán, scattered fù and prose, plus fragments of the Shǔ wáng běn jì 蜀王本紀 and Qín qīng yīng 琴清英 quoted in lèishū. His preface is dated Wànlì yǐwèi (= 1595, ninth month). The preface defends Yáng Xióng against the standard charge of having served the usurper Wáng Mǎng — a defense the Sìkù compilers reject in their tíyào. CBDB lists three homonyms of differing dynasty (Sòng, Yuán, Míng); the Míng entry (CBDB 214367) is the figure here, but no birth/death years are recorded.
