Yì xuánjī 易璇璣
The Pole-Star Wheel of the Yì
by 吳沆 Wú Hàng (zì Déyuǎn 德遠, fl. 1146, of Línchuān 臨川)
About the work
A short, sharply organized topical treatise on the Yì, presented as a memorial to Gāozōng’s court at Hángzhōu in Shàoxīng 16 (1146) by the Línchuān commoner-scholar 吳沆 Wú Hàng together with his brother 吳澥 Wú Xiè. Three juan, twenty-seven essays at nine essays per juan. Not a hexagram-by-hexagram commentary but a thematic re-articulation of the Yì’s philosophical-political teaching organized around the Tuàn zhuàn as the master access-point to canonical-text reading. The title is taken from 王弼 Wáng Bì’s Zhōuyì lüèlì Míng tuàn 周易略例·明彖 chapter — chǔ xuánjī yǐ guān dà yùn 處璇璣以觀大運 (“dwell at the Pole-Star wheel to observe the great revolutions”) — i.e. the Tuàn is to the canonical text what the Pole-Star is to the heavens: the still point from which the larger movements come into focus.
The twenty-seven essay-titles map a complete topical curriculum on the Yì: Fǎ Tiān (Modelling Heaven), Tōng liùzǐ (Mastering the Six Children), Guì zhōng (Honoring the Centre), Chūshàng dìng wèi (Fixing the First-and-Upper Positions), Liùjiǔ dìng míng (Fixing the Names of Six-and-Nine), Tiāndì biàn guà (Heaven-and-Earth Change Hexagrams), Lùn biàn yǒu sì (On There Being Four Modes of Change), Yǒu xiàng (On Imagery), Qiú tuàn (Seeking the Tuàn), Míng wèi (Clarifying Position), Míng jūndào (Clarifying the Way of the Sovereign), Míng jūnzǐ (Clarifying the Gentleman), Lùn yǎng (On Nourishment), Lùn xíng (On Punishment), Lùn fá (On Punitive Expedition), Biàn shèng (Discriminating the Sage), Biàn nèiwài (Discriminating Inner-and-Outer), Biàn jíxiōng (Discriminating Fortune-and-Misfortune), Tōng guà (Mastering Hexagrams), Tōng xiàng (Mastering Imagery), Tōng yáo (Mastering Lines), Tōng cí (Mastering Wording), Tōng zhèng (Mastering Verification), Shì guà (Explaining Hexagrams), Shì xì (Explaining the Xìcí), Cún hùtǐ (Preserving the Interlocked Body), Guǎng yǎn (Broad Elaboration). Wú’s preface frames the project: upper juan articulates “the natural pattern of the Heavenly principle”; middle juan discusses “the cultivation of human affairs”; lower juan “supplies the failures of the commentary tradition.”
The work is one of the few Sòng Yì texts to centre the project explicitly on the Wáng Bì hermeneutical principle — Tuàn as the privileged access-point — and to articulate a topical (rather than hexagram-sequential) curriculum. The Sìkù tiyao notes 胡一桂 Hú Yīguì’s record of an additional Wú Hàng work, Yì lǐ tú shuō 易禮圖說 with six huò wèn sections and twelve illustrative scrolls — long lost. Wú’s Sān fén xùn yì 三墳訓義 (a commentary on the spurious Sānfén 三墳 text), also presented to court in 1146, was refuted by the Tàixué bóshì 王之望 Wáng Zhīwàng and is also lost. Wú Hàng’s other surviving work is the Huánxī shī huà 環溪詩話 (“Pool-Embracing Poetry-Talks”), preserved in the Yǒnglè dàdiǎn and registered separately in the Sìkù belles-lettres section.
The composition window 1140–1146 covers the run-up to the 1146 court presentation; precise narrower dating not currently established.
Tiyao
We respectfully submit that Yì xuánjī in three juan was composed by 吳沆 Wú Hàng of the Sòng. Hàng, zì Déyuǎn, was a man of Línchuān. In Shàoxīng 16 [1146] he and his younger brother Wú Xiè went to the imperial residence to present writings: Xiè presented Yǔnèi biàn 宇内辨 and Lìdài jiāngyù zhì 厯代疆域志; Hàng presented Yì xuánjī and Sān fén xùn yì. Xiè’s books are not transmitted. Hàng’s Sān fén xùn yì was refuted by the Tàixué bóshì 王之望 Wáng Zhīwàng, and is also not transmitted. Only this book survives.
In all twenty-seven discourses: Fǎ Tiān, Tōng liùzǐ, Guì zhōng, Chūshàng dìng wèi, Liùjiǔ dìng míng, Tiāndì biàn guà, Lùn biàn yǒu sì, Yǒu xiàng, Qiú tuàn, Míng wèi, Míng jūndào, Míng jūnzǐ, Lùn yǎng, Lùn xíng, Lùn fá, Biàn shèng, Biàn nèiwài, Biàn jíxiōng, Tōng guà, Tōng xiàng, Tōng yáo, Tōng cí, Tōng zhèng, Shì guà, Shì xì, Cún hùtǐ, Guǎng yǎn. Every nine essays make one juan. The self-preface says the upper juan clarifies the natural pattern of Heavenly principle; the middle juan discusses the cultivation of human affairs; the lower juan supplies the failures of the commentary tradition. Its great purport rests on observing the Tuàn — and through the Tuàn seeking the hexagram, seeking the imagery, seeking the yáo. The title “Xuánjī” comes from the Yì lüèlì Míng tuàn phrase “dwell at the Pole-Star wheel to observe the great revolutions.”
胡一桂 Hú Yīguì records that Hàng also had a Yì lǐ tú shuō, with six huò wèn and twelve illustrative scrolls; we have not seen the book — presumably also scattered and lost. Only his Huánxī shī huà, recorded for him by others, is still preserved in the Yǒnglè dàdiǎn. We now register it separately in the belles-lettres section.
Respectfully revised and submitted, ninth month of the forty-sixth year of Qiánlóng [1781].

Abstract
吳沆 Wú Hàng (fl. 1146), of Línchuān 臨川 in Fǔzhōu 撫州 (modern Jiāngxī), was a commoner-scholar with no examination success and no recorded official position; he attempted to enter the court through a 1146 presentation of writings but was rebuffed (his Sān fén xùn yì was specifically refuted by 王之望 Wáng Zhīwàng), and faded from the record thereafter. His brother 吳澥 Wú Xiè was a similarly self-styled scholar, with Yǔnèi biàn (a treatise on the inner-versus-outer political-administrative distinction) and Lìdài jiāngyù zhì (a historical-geographic treatise); both works lost.
The Yì xuánjī is methodologically the most distinctive Sòng-period topical Yì treatise: rather than glossing the canonical text hexagram-by-hexagram, it articulates the Yì’s teaching as a structured topical-philosophical curriculum, with the Tuàn zhuàn as the privileged access-point. Wú’s project — to reorganize the Yì’s implicit doctrine into a coherent topical exposition — is closer in spirit to a Tài xuán 太玄-style philosophical-cosmological systematization than to a conventional commentary. The four-fold change-classification (biàn) — articulated in the Lùn biàn yǒu sì essay — is one of the more substantive Sòng-period analytical contributions to Yì-hermeneutics.
The lost Yì lǐ tú shuō — six huòwèn (catechetical) sections and twelve illustrative scrolls — would have been the visual-and-cosmological complement to the textual-and-topical Yì xuánjī; its loss is a real lacuna for understanding Wú’s method.
The work’s reception is thin: a single Hú Yīguì citation (in the Zhōuyì běnyì fù lù zuǎn shū tradition) is the principal Sòng-Yuán-Míng witness. The Yǒnglè dàdiǎn preserved it in fragmentary form; the Sìkù WYG reissue is the modern access-point.

Other points of interest
The work’s deliberate centring on Wáng Bì’s “chǔ xuánjī yǐ guān dà yùn” — Wú Hàng read this as a methodological prescription, not just rhetoric — is a small monument of mid-Sòng yìlǐ engagement with Wáng Bì’s hermeneutical theory. The Wáng Bì Lüèlì is rarely treated as a theoretical document independent of its commentarial application elsewhere in the Sòng tradition; Wú Hàng is one of the exceptions.
The 1146 imperial-presentation context — two brothers from a regional commoner background trying to enter Hángzhōu’s elite by presenting four writings collectively — is a small but vivid case-study of mid-Southern-Sòng meritocratic-aspirational scholarship. Their failure (the Wáng Zhīwàng refutation) illustrates the gate-keeping role of the Tàixué bóshì corps under the post-1142 settled court.
