Diāo Bāo 刁包 (1603–1669), zì Méngjí 蒙吉, hào Yòngliù jūshì 用六居士, was a late-Míng / early-Qīng Confucian scholar from Qízhōu 祁州 (Bǎodìng 保定, modern Héběi 河北). He passed the provincial examination in Tiānqǐ xīnmǎo 天啟辛卯 = 1631 (the catalog meta records the date as the Tiānqǐ / xīnmǎo year, which falls in 1631) and was active in the Dōnglín-affiliated northern circle. After the Míng collapse he refused Qīng appointments and lived in retreat. His main work in the Sìkù is the Yì zhuó 易酌 (KR1a0121) in fourteen juàn, an yìlǐ commentary that takes Chéng Yí’s Yìchuán and Zhū Xī’s Běnyì as its principal authorities while excluding the post-Sòng chart-tradition.
Diāo’s grandson Diāo Xiǎnzǔ 刁顯祖 in Yōngzhèng 雍正 1 (1723) added supplementary material — an introductory fánlì, the Záguà diagrams, and small-character jǐn àn 謹案 notes throughout the body — and re-issued the work. The Sìkù edition preserves both Diāo’s original text and Xiǎnzǔ’s additions. The original was nearly cut to blocks during the early Kāngxī period by Lù Lǒngqí 陸隴其 (then in office at Língshòu 靈壽) but the project did not proceed.
CBDB has no securely identifiable entry for him; standard Qīng biographical sources give the dates 1603–1669 followed here.
