Lǐ Gōng 李塨 (1659–1733), zì Gāngzhǔ 剛主, hào Shùgǔ 恕谷, was the principal pupil and intellectual heir of Yán Yuán 顏元 (1635–1704), and one of the leading figures of the YánLǐ 顏李 school — the early-Qīng Lǐxué revisionism that emphasized practical-applied learning (shí xué 實學) against SòngMíng metaphysical and mind-learning trends. Native of Lǐxiàn 蠡縣 (Bǎodìng 保定, modern Héběi 河北). He passed the jǔrén in Kāngxī gēngwǔ 康熙庚午 = 1690 and held office as Education Director of Tōngzhōu (Tōngzhōu xué zhèng 通州學正).
His principal Yìjīng work is the Zhōuyì zhuàn zhù 周易傳註 (KR1a0140) in seven juàn, with appended Zhōuyì shì kǎo 周易筮考 in one juàn. The work programmatically interprets the Yì as concerned with human affairs (rén shì 人事) rather than heavenly principle (tiān dào 天道) — this reading derives from the YánLǐ school’s broader practical-Confucian orientation. The work integrates Lǐ Dǐngzuò’s 李鼎祚 Jíjiě (Hàn material) with the recent early-Qīng kǎozhèng (Máo Qílíng’s 毛奇齡 Zhòngshì Yì and Tú shū yuán shùn biàn; Hú Wèi’s 胡渭 Yìtú míng biàn).
Lǐ’s broader YánLǐ school program is set out in his Sì shū zhuàn zhù 四書傳註 and other classical commentaries. He also wrote on music, ritual, and astronomy.
