Lǐ Xiányòng 李咸用 (fl. Xiántōng–Qiánfú, ~860s–870s; of Lǒngxī by ancestral seat). The header inscription of his collection identifies him as a tuīguān (Examining Inspector) — a regional staff position. He failed the jìnshì repeatedly and held subordinate posts in regional offices; his career details are scant in standard sources.
Lǐ’s verse — preserved in the SBCK Pīshā jí — is conservative, image-careful late-Táng yuèfǔ-style and quatrain work, with strong influence from Bào Róng 鮑溶 and from Zhāng Wèi’s school typology. The title Pīshā (“sand-sifting”) is one of the more self-deprecating Tang collection-titles.
