Lǐ Fùyán 李復言, mid-to-late Táng chuánqí author, fl. c. 820–850, of uncertain origin. The name appears in the bibliography of Tàipíng guǎngjì and is firmly attached only to the Xù xuánguài lù 續玄怪錄 / Xù yōuguài lù 續幽怪錄, the continuation of Niú Sēngrú’s 牛僧孺 Xuánguài lù 玄怪錄. The standard modern identification (following Wáng Mèngōu 汪夢鷗 in his 1972 study Tángrén xiǎoshuō yánjiū, Tángrén xiǎoshuō yánjiū sānjí, and Allen 2014) is with the jìnshì Lǐ Liàng 李諒, zì Fùyán 復言, recorded in the Tángshū and Páng Yánbāng 龎彥邦’s career notice — but the identification is not unanimous, and “Lǐ Fùyán” may also be a pen-name. He is not catalogued in CBDB under either name; his lifedates remain unfixed beyond the fl. 820s–850s window inferred from the dating of the Xù xuánguài lù’s internal references and its first attestation in WǎnTáng bibliographies.
The work attributed to him in the Kanripo corpus is KR3l0126 Xù yōuguài lù 續幽怪錄 (also titled Xù xuánguài lù 續玄怪錄; the yōu form is a Sòng tabu-substitution for the Sòng Wényùndìng 文淵帝 character 玄). A chuánqí / zhìguài collection in 4 juàn preserved in the Sìbù cóngkān facsimile of the Sòng Línān printed edition, recounting some 30+ tales of dreams, prophecy, ghosts, transformations, and the supernatural retribution; some of its tales (e.g. Dìnghūn diàn 定婚店, the locus classicus of the yuèlǎo “old man under the moon” matchmaking-thread motif) are among the most famous in the Táng chuánqí repertoire.
