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 Pǐ-Tài 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.
