Dǒng Shǒuyù 董守諭 (1596–1664), zì Cìgōng 次公, was a late-Míng / early-Qīng Yìjīng scholar from Yínxiàn 鄞縣 (Níngbō 寧波, Zhèjiāng 浙江). He was active under both the Míng and the early Qīng (his death falling in Kāngxī 3 = 1664). His one surviving work in the Sìkù is the Guà biàn kǎo lüè 卦變考略 (KR1a0112) in two juàn, completed in Chóngzhēn guǐwèi 崇禎癸未 = 1643.
The work treats the guà biàn 卦變 (hexagram-variation) doctrine as a problem in the history of Yìxué. Dǒng surveys the Hàn-period sources — Lǎng Yǐ 郎顗, Jīng Fáng 京房, Shǔ Cái 蜀才, Yú Fān 虞翻 — collates them with the Sòng commentators’ redactions (most importantly Zhū Xī’s twelve-cycle guà biàn tú 卦變圖 in the Běnyì’s ninth diagram), and finds Zhū’s redaction internally inconsistent (e.g., on Suí, Kùn, Shìkè, and Wèijì he derives them from PǐTài in the diagram but from elsewhere in the running commentary). Dǒng’s own reading takes the trigram-component as its base — for example, Bǐ 比 derived from Shī 師 by yīnyáng inversion of one line. The Sìkù editors note that, while Dǒng’s argument is generally well-grounded, his closing claim that hexagram-variation is the original meaning of the Yì’s composition (rather than merely one strand of it) is overstated.
