Huáng Zōngyán 黃宗炎 (1616–1686), zì Huìmù 晦木, was an early-Qīng Yìjīng and Lǐxué scholar from Yúyáo 餘姚 (Shàoxīng 紹興, modern Zhèjiāng 浙江), and the younger brother of Huáng Zōngxī 黃宗羲 (黃宗羲). Like his brother he was a Míng loyalist who refused Qīng office, and like his brother he wrote on the Yì in the kǎozhèng and anti-chart-tradition vein. His major work in the Sìkù is the Zhōuyì xiàng cí 周易象辭 (KR1a0124) in twenty-two juàn, with the appended Zhōuyì xún mén yú lùn 周易尋門餘論 in two juàn and Tú xué biàn huò 圖學辨惑 in one juàn.
His method takes the yìlǐ line strongly, expounding the canonical text through principle while polemicizing extensively against the Chén Tuán 陳摶 chart-tradition (especially in the Tú xué biàn huò). The Sìkù editors’ notice grants the work substantive contribution while objecting to two specific habits: occasional eccentric readings (e.g. taking the Guī mèi 歸妹 xū 須 as referring to xū fà 鬚髮 “beard-and-hair”) and excessive reliance on seal-script etymology to gloss the canonical characters (a practice the editors compare to Wáng Ānshí’s 王安石 Xīn yì 新義 Zì shuō 字說). The Tú xué biàn huò in particular is one of the foundational early-Qīng works of the chart-tradition critique, alongside 黃宗羲’s Yì xué xiàng shù lùn (1690s) and Hú Wèi’s Yìtú míng biàn (1706).
