Dài Kǎizhī 戴凱之
Late-Jìn / LiúSòng / Southern-Qí scholar and pǔlù author, native of Wǔchāng 武昌. Zì Qìngyù 慶預 or Qìngyù 慶豫 (the two characters being graphically similar and the sources disagreeing — the Sìkù editors note the discrepancy without resolving it).
The Suíshū Jīngjí zhì lists his Zhúpǔ 竹譜 (KR3i0040) anonymously; the Jiù Tángshū Jīngjí zhì lists it under his name without specifying period; Zuǒ Guī’s Bǎichuān xuéhǎi assigns him to the Jìn dynasty. The Sìkù editors confirm by internal evidence — citations from Yú Yù 虞豫 Kuàijī diǎnlù, Cháng Kuān 常寬 Shǔ zhì, Xú Guǎng 徐廣 Zájì, Shěn Yíng 沈瑩 Línhǎi shuǐtǔ yìwù zhì, Guō Pú 郭璞 Shānhǎijīng zhù and Ěryǎ zhù (all of these being Jìn-period works), and especially the use of Zhèng Xuán’s reading of the Shàngshū “Xiǎodǎng jí fū” (which Kǒng Yǐngdá’s mid-Tang annotation would later supersede) — that the work must be pre-Tang and most likely a late-Jìn (= early fifth-century) composition. The fl. range 400–490 reflects this uncertainty: the work could be by a person of the LiúSòng or even Southern Qí, with the Jìn attribution traditional but possibly inaccurate. The Lǐ Shàn annotation to Mǎ Róng’s Chángtián fù (mid-Tang) and Duàn Gōnglù’s Běihù lù (Tang) both cite the work, confirming pre-Tang date.
His one attested work, the Zhúpǔ 竹譜 in one juàn, is the foundational Chinese bamboo-monograph and one of the earliest surviving pǔlù in the entire genre. Composed in sìyán (four-character) rhymed verse with self-commentary, in a deliberate echo of the Shàngshū and Zhōulǐ classical style.
