Lǐ Jiànxūn 李建勳 (873?–952), of Lǒngxī 隴西 (the jùnwàng / ancestral-clan designation; his actual residence was Jīnlíng / Nánjīng). Foundational poet of the early Southern-Táng 南唐 court and the dynasty’s first-generation chancellor. CBDB id 92981 confirms 873?–952.
His career began in the Wú state (the late-Táng successor regime in the JiāngHuái region under Yáng Hàngmì 楊行密 and successors). With the Wú-Southern-Táng transition under Lǐ Biàn 李昪 (Lièzǔ, r. 937–943), Lǐ Jiànxūn rose to Tóng zhōngshū ménxià píngzhāngshì (chancellor) in the early Shēngyuán reign. He was retired with senior-honor titles in the early 940s and lived out his final years at Jīnlíng in poetic retirement, dying in 952 at the start of the Bǎodà reign of Lǐ Jǐng 李璟. The collection’s title — Lǐ chéngxiàng (Chancellor Lǐ) — refers to this terminal office.
His poetry is preserved in the two-juǎn fragmentary KR4c0114 Lǐ chéngxiàng shījí (SBCK reprint of the late-Sòng Línān Chénzhái cutting). Approximately 85 poems survive of an original 30-juǎn corpus (per Sòngshǐ yìwénzhì). His addressees document the early-Southern-Táng poetic community — Sūn Fāng 孫魴, Pī Bīn 沈彬, zhèngshì xuéshì and other Southern-Táng courtiers; his style — calmer and more meditative than Wéi Zhuāng 韋莊 and less imagistically dramatic than Guànxiū 釋貫休 or Qíjǐ 釋齊己 — defines a transitional voice between late-Táng and Sòng shī. A small body of cí is also attributed to him (preserved in the Quán TángWǔdài cí).
