Zhào Rénjǔ 趙仁擧, biography unrecorded, is known only as the early-Yuán annotator of Fán Zōngshī’s 樊宗師 Jiàngshǒu jūyuánchí jì (= KR4c0063). His work supplied the base commentary later supplemented by Wú Shīdào 吳師道 (1313, with 22 additions and 60 corrections) and Xǔ Qiān 許謙 (1320, with 41 further additions). Zhào’s annotation responded to a specific bibliographic gap: the two Táng commentaries on Fán Zōngshī’s piece by Wáng Shèng 王晟 and Liú Chén 劉忱 — recorded by Lǐ Zhào in his Guóshǐ bǔ — were already lost by the early Yuán.
No other works recorded under his name; CBDB has no matching entry. The Sìkù editors note only that he was clearly active before Wú Shīdào’s Huángqìng 2 (1313) supplement.
