Career.

  • Jíxián xuéshì 集賢學士
  • Guózǐ jìjiǔ 國子祭酒 (Imperial Academy Chancellor) — succeeding Xǔ Héng

Foundational retreat. Originally dug a chamber in the earth at the base of Mt. Zhōngnán 終南山; arranged the Six Classics and the Hundred-Schools commentaries on left and right; pursued sīsuǒ qí yì zhì yú wàngmèi (sought-and-pondered their meaning to the point of forgetting sleep) for thirty years — emerging with comprehensive scholarly mastery.

Scholarly distinction. Expert across the Six Classics and Hundred Schools; especially profound in:

  • Sānlǐ 三禮 (the three Confucian ritual classics: Yílǐ, Lǐjì, Zhōulǐ)
  • 易 (Classic of Changes)
  • Liùshū 六書 (six script-categories — the canonical Chinese paleographical-classification scheme)

Teaching method. Strictly required the Xiǎoxué 小學 as the entry-point for all students.

Doctrinal lineage. Yuánshǐ characterization: “Uniformly takes ZhūSì (Confucius and Mencius) as origin, with LiánLuò Kǎotíng (the Zhōu Dūnyí / Chéng Brothers / Zhū Xī lineage) as basis.”

Collection. Qínzhāi jí KR4d0490 — original 15 juàn compiled by Sū Tiānjué 蘇天爵 in Zhìzhèng 4 (1344), cut at Huáidōng. The Sìkù Yǒnglè dàdiǎn reconstruction preserves 8 juàn.

Within the Kanripo corpus. KR4d0490 Qínzhāi jí 勤齋集 (撰).

Reference. Yuánshǐ Rúlín zhuàn (j. 189); Sū Tiānjué’s Zīxī jí preserves the Mùzhì míng for Xiāo.
