Zhào Cǎi 趙采 (lifedates not securely recorded; fl. early-mid Yuán, c. 1290–1320), zì Déliàng 德亮, hào Lóngzhāi 隆齋, of Tóngchuān 潼川 in Sìchuān (modern Sāntái, Sìchuān). CBDB id 110360 (placed as Yuán dynasty 18, without dates); CBDB has multiple Sòng-period Zhào Cǎi entries (id 99699, 688206), but the Yuán-period author of KR1a0074 is most plausibly id 110360.
Within the Kanripo corpus he is the author of KR1a0074 Zhōuyì Chéng-Zhū zhuànyì zhézhōng 周易程朱傳義折衷 — a 33-juan Yuán-period combined-edition of Chéng Yí’s Yì zhuàn and Zhū Xī’s Zhōuyì běnyì, with Zhào Cǎi’s own zhézhōng (balancing) judgments. The work covers only the upper-and-lower jīng (canonical text proper); the Xìcí and below are not treated.
Methodologically a triple-canon synthesizer of Shào Yōng (for xiàngshù) + Chéng Yí (for yìlǐ) + Zhū Xī (for bǔshì and gǔyì recension), augmented with Hàn-Wèi-Táng xiàngshù technical apparatus (hùtǐ, fēifú, nàjiǎ) where the Chéng-Zhū-Shào triad had not extended. The position is methodologically more comprehensive than Dǒng Kǎi’s strict-Chéng-Zhū Fù lù (KR1a0061) but more orthodox than the heterodox-leaning xiàngshù writers.
The work’s bibliographic-historical significance: Zhào Cǎi (and Dǒng Kǎi) already split-and-attached the Běnyì into the Chéngzhuàn (Wáng-Bì-recension) structure, anticipating the Míng Yǒnglè Dàquán by a century. Modern Yì-scholarship recognizes the multi-stage development Dǒng Kǎi (1266) → Zhào Cǎi (early-14th c.) → Hú Guǎng (1415) — correcting Gù Yánwǔ’s earlier exclusively-blaming-Hú-Guǎng narrative.
