Wú Guìsēn 吳桂森, zì Shūměi 叔美, was a late-Míng Yìjīng scholar from Wúxī 無錫, and the principal pupil of Qián Yīběn 錢一本 (錢一本) in Yìxué. According to his own preface to the Zhōuyì xiàng xiàng shù 周易像象述 (KR1a0108), dated Tiānqǐ yǐchǒu 天啟乙丑 = 1625, he received instruction from Qián Yīběn over fifteen years from Wànlì gēngxū 萬曆庚戌 = 1610 — when he first saw Qián’s Xiàng xiàng guǎn jiàn 像象管見 (KR1a0104) — through guǐchǒu 癸丑 (1613, when he hosted Qián at the Dōnglín 東林 academy and saw the Xiàng chāo 像抄), and Wànlì dīngsì 萬曆丁巳 (1617, when he traveled to Mount Guīshān 龜山 with Qián and saw the Xù chāo 續抄). Qián died in 1610 (the Sìkù notice itself observes that this seventeen-year sustained instruction is partly mythical — Qián’s death year preceded Wú’s stated 1610 gēngxū meeting; the seventeen-year span describes the gestation and revision of Wú’s own Xiàng xiàng shù, drawing on Qián’s three earlier works).
Wú also studied at the Dōnglín Academy under Gù Xiànchéng 顧憲成 and Gāo Pānlóng 高攀龍 (高攀龍). The Dōnglín Lǐxué network of Wúxī thus stands behind both Wú’s Yì-writing and Qián’s. The Xiàng xiàng shù preserves marginal evaluations by Gāo Pānlóng (annotated in red) and Qián Yīběn (anonymous) at the head of the work.
