Yáng Shíqiáo 楊時喬 (1531–1609), courtesy name Yíqiān 宜遷, was a Míng-dynasty official from Shàngráo 上饒 (modern Jiāngxī). He took the jìnshì in the forty-fourth year of Jiājìng (yǐchǒu 乙丑, 1565) and rose through provincial and central posts to become Lìbù zuǒ shìláng 吏部左侍郎, Vice-Minister of the Left of the Bureau of Personnel — the senior personnel-administration deputy in the Wànlì court. Within his ministerial career he served also at the Court of the Imperial Stud (Tàipú sì 太僕寺) — at both the Nánjīng and Běijīng establishments — eventually styling himself, in his own self-printed preface to KR2m0052 Mǎ zhèng jì 馬政紀, qián Tàipú sì qīng 前太僕寺卿 (“former Director of the Court of the Imperial Stud”), although the Míngshǐ biography records his Stud-court office only as Tàipú sì chéng (Senior Assistant). The Sìkù compilers, following Yáng’s signature, treat the Míngshǐ as in error here. He also wrote a Yìjīng commentary, Zhōuyì gǔjīn wén quánshū 周易古今文全書, and was a respected late-Wànlì opponent of the commutation of the Míng horse-administration to silver — the polemical core of Mǎ zhèng jì. CBDB (125336) gives him birth/death 1531/1609, “from Jiājìng 9 to Wànlì 37.”
