Dài Rèn 戴任 (fl. late Wànlì, c. 1600), late-Míng compiler. Co-author with 馮應京 of the Yuèlìng guǎngyì 月令廣義 (Wànlì 30 / 1602; 24 juan), the late-Míng yuèlìng compendium that supplied the proximate base for the Kāngxī-era KR2j0002 Yùdìng yuèlìng jíyào. He is identified as the editor / supplementer who reorganized and expanded Féng’s draft. Not in CBDB; biographical detail is scant. The Kāngxī imperial preface to Yuèlìng jíyào names him alongside Féng as the Míng-time originators of the genre’s last comprehensive formulation.
