Shǐ Bóxuán 史伯璿 (YuánMíng transition), zì Wénjī 文璣, was a late-Yuán / early-Míng Lǐxué commentator of Píngyáng 平陽 (Wēnzhōu, Zhèjiāng). His Guǎnkuī wàipiān 管窺外篇 (KR3a0075) was completed in Zhìzhèng dīngwèi (1367) — the year before the Yuán dynasty fell, on Yáng Shìqí’s reasoning placing him just over the YuánMíng border. He also wrote a Sì shū guǎn kuī 四書管窺 in 5 juan (now extant in fragments through the Yǒnglè dàdiǎn and Huáng Yújì’s Qiānqǐngtáng shūmù), of which the Wàipiān is the supplementary essay-volume.
