Northern-Sòng 北宋 scholar-examinee, active c. 1099–1121 at the Háng zhōu 杭州 Prefectural Academy. Author of the major Sòng Lièzǐ commentary [[KR5c0121|Chōng xū zhì dé zhēn jīng jiě 沖虛至德真經解]] (DZ 730, c. 1110).
Status. Identified in his commentary as Nèi shè shēng 內舍生 (“Inner Hall Student”) of the Hángzhōu Prefectural Academy (Háng zhōu zhōu xué 杭州州學). This was a mid-level status in the three-grade examination system (sān shè fǎ 三舍法) that the Northern-Sòng reform administration had introduced for prefectural academies between 1099 and 1121 (Huáng Sòng shí cháo gāng yào 14.6b; 18.9b).
Dating. Active between 1099 and 1121 — the 22-year window of the sān shè system’s application to prefectural academies. No precise lifedates. Apart from his commentary, he is otherwise unknown in the Sòng biographical record.
Work. His sole known work is the Chōng xū zhì dé zhēn jīng jiě (DZ 730) — a 20-juàn commentary on the Lièzǐ. Considered one of the two best Sòng Lièzǐ commentaries (with Lín Xīyì’s [[KR5c0120|kǒu yì]]) and praised by the Qīng Sìkù editors for its elegance and philosophical depth. Modelled on Guō Xiàng’s 郭象 (郭象) Zhuāngzǐ commentary in style — intuitive-interpretive rather than philological.
Regional affiliation. Hángzhōu — the major cultural-scholarly centre of the Zhè jiāng 浙江 region, which would become the Southern-Sòng capital from 1138. Jiāng Yù’s Northern-Sòng-era activity at the Hángzhōu academy places him in the same intellectual milieu that would later nurture major Southern-Sòng figures including Lín Xīyì (mid-13th cent.) and other FújiànZhèjiāng Daoist-Confucian scholar-officials.
