Dū Jié 都絜
Style name Shèngyǔ 聖與. Native of Dānyáng 丹陽 (modern Jiāngsū). Active in the Southern-Sòng Shàoxīng era (1131–1162); precise lifedates not recoverable.
Held Lìbù lángzhōng 吏部郎中 (“Director of the Bureau of Personnel”) at Gāozōng’s Hángzhōu court, and was prefect (Zhī fǔshì 知府事) of Déqìngfǔ 德慶府 in modern Guǎngdōng. Father Dū Yù 都郁 (zì Zǐwén 子文) was a Huìzhōu jiàoguān and a lifelong Yì-student; Dū Jié’s commentary builds on his father’s teaching.
His sole surviving work:
- [[KR1a0027|Yì biàntǐ yì]] 易變體義 in twelve juan (sixteen in the Sòngshǐ recension) — the most systematic Sòng-period application of the Zuǒzhuàn’s “X 之 Y” hexagram-change formulation to the entire Yì. Each of the 384 lines of the canonical text is given one essay-length biàntǐ 變體 reading. Zēng Jǐ 曾幾’s preface dated Shàoxīng 29 (1159). Recovered for the Sìkù from the Yǒnglè dàdiǎn; the present recension is missing seven hexagrams and the last four lines of Jìn.
His father Dū Yù is recorded only in CBDB without further detail; no separate works survive under Dū Yù’s name.
