Zhèng Hǔchén 鄭虎臣 (d. 1275)
Zì Jǐngzhào 景兆. Native of Sūzhōu (Wújùn). Late-Southern-Sòng official who once served as Kuàijī wèi 會稽尉 (Kuàijī military judge). At the beginning of Déyòu 1 (1275) — as the Southern Sòng court was collapsing under Mongol pressure — he volunteered to serve as the jiānyā (supervising guard) escorting the disgraced former chief minister Jiǎ Sìdào 賈似道 to exile. At Mùmiánān 木綿菴, Zhèng Hǔchén killed Jiǎ Sìdào — an act famously recorded in Sòng historiography (the Sòngshǐ Jiǎ Sìdào zhuàn) and widely celebrated in Yuán and later Chinese moral-political literature as the righteous execution of a treasonous minister.
Zhèng’s principal scholarly work is the Wúdū wéncuì 吳都文粹 KR4h0057 in 9 juǎn — a regional anthology of Sūzhōu literature compiled probably ca. 1265–1275. His own fate after the Jiǎ Sìdào execution is unclear; he probably died in the late Sòng collapse. No firm birth year; the Mùmiánān episode and Déyòu 1 (1275) are fixed in the Sòngshǐ.
