Eastern-Jìn scholar of the second half of the 4th century. The Suízhì 隋書經籍志 records him as Guózǐ zhùjiào 國子助教 — Auxiliary Instructor of the Directorate of Education — and credits him with the Yèzhōng jì 鄴中記 KR2i0004 in two juàn, his only known work. Beyond this office, no further biographical detail survives in the standard histories or in the Jìnshū (where he has no biography of his own). The graph 翽 (huì, the rustle of pinions) is sometimes confused with its near-homophone 翟 (dí) in early printings; CBDB has no entry. The Yèzhōng jì, restricted in its original form to the reign of Shí Hǔ 石虎 (r. 334–349), points to a floruit in the late 4th century. The book was lost in the Sòng and survives only through Sìkù-editor reconstruction from lèishū (chiefly the Yǒnglè dàdiǎn).
