Hú Zēng 胡曾 (fl. Xiántōng–Guǎngmíng, c. 860–880), of Shàoyáng 邵陽 (modern Húnán). His career was spent entirely in regional staff positions: Hànnán cóngshì in late Xiántōng (per Chén Zhènsūn’s Shūlù jiětí), jìshì (manuscript secretary) under Gāo Pián 高駢 at Shǔ (per Hé Guāngyuǎn’s Jiànjiè lù), composing the proclamation to the Xīshān bāguó (Eight States of the Western Mountains). His career ended in regional staff service.
Hú’s principal work is the 150-poem Yǒngshǐ shī cycle (KR4c0091) — each poem keyed to a historical place-name — that became, contrary to its limited literary merit (the Sìkù tíyào finds the verse “shallow in entrustment, low in form”), a standard primer-text for late-imperial elementary historical-geographical education. The cycle circulated in many late-Míng / Qīng commercial reprints with various commentaries.
