Qián Yìfāng 錢義方, zì Zǐyí 子宜, was a late-Yuán Yìjīng scholar from Wúxīng 吳興 (modern Húzhōu 湖州, Zhèjiāng 浙江). He once passed the jìnshì 進士 examination — at his self-preface (1346) he gives himself the title qián jìnshì 前進士 (“former jìnshì”) — but his official career is otherwise undocumented.
His one known work, the Zhōuyì túshuō 周易圖說 (KR1a0087), is dated zhìzhèng bǐngxū 至正丙戌 (1346) by his own preface. He records there that he had been “respectfully reading the scripture and the wings of the Yì and studying them for thirty years” before composing the work, putting his sustained engagement with Yìxué back to roughly the late 1310s. CBDB places his attested activity at 1346, which corresponds to the date of the preface.
The work is a chart-based exposition (túshuō 圖說) of the Yì in the line of Chén Tuán 陳摶, Mù Xiū 穆修, Lǐ Zhīcái 李之才, and Shào Yōng 邵雍, but with several deliberate departures from received doctrine: Qián holds, against the Kǒng Ānguó 孔安國 / Lǚ Zǔqiān line, that only the Hétú 河圖 — not the Luòshū 洛書 — was the basis of Fú Xī’s making of the Yì, and that Zhū Xī 朱熹 in his Běnyì still showed a residual hesitation in attributing the prior- and posterior-heaven hexagram positions to Shào Yōng rather than directly to the sages.
