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 ChéngZhū 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 HànWèiTáng xiàngshù technical apparatus (hùtǐ, fēifú, nàjiǎ) where the ChéngZhūShào 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.
