Bāo Yí 包儀, zì Yǔxiū 羽修, was an early-Kāngxī Yìjīng and xiàngshù-school scholar from Xíngtái 邢臺 (Shùndé 順德, modern Héběi 河北). He was a bágòng 拔貢 (selected tribute student) whose career particulars are otherwise undocumented. The Sìkù notice describes him as “a poor and isolated scholar firmly resolved to stand on his own.”
According to his own preface to the Yì yuán jiù zhèng 易原就正 (KR1a0135), he had heard of Shào Yōng’s 邵雍 Huáng jí jīng shì 皇極經世 in his youth but had no access to a copy. From Shùnzhì xīnmǎo 順治辛卯 = 1651 to Kāngxī jǐyǒu 康熙己酉 = 1669 he failed the jìnshì examination seven times; in extreme poverty he traveled to Máchéng 麻城 and at last obtained a copy of the Huáng jí jīng shì in the household of Wáng Kěnán 王可南; he then went to Jiāngníng 江寧 (Nánjīng) and lived from monastery alms while studying it for a full year before achieving understanding. The work was completed nine years later (in the early-to-mid 1680s) after surviving a fire and the Wú Sānguī 吳三桂 rebellion (the fán nì 藩逆 disaster).
His Yì yuán jiù zhèng in twelve juàn is the principal early-Qīng Yì commentary in the Shào Yōng / Chén Tuán xiāntiān tradition that explicitly defends the chart-tradition against the early-Qīng kǎozhèng attacks. Methodologically idiosyncratic: Bāo holds that the Luòshū 洛書 has no relation to the Yì, but reads the Hétú and Shào Yōng’s prior-heaven scheme as the foundational structure.
