Dù Běn 杜本 (zì Bóyuán 伯原, hào Qīngbì 清碧, 1276–1350), Yuán-period recluse-literatus, polymath, and physician of Qīngjiāng 清江 (modern Jiāngxī). He refused all official summons under Yuán Shùndì 順帝, retreated to Wǔyíshān 武夷山 where he built the studio Sīxuézhāi 思學齋 / Huáiyǒuxuān 懷友軒, locally known as the Pìnjūn zhái 聘君宅 (“the dwelling of the summoned gentleman”). His learning spanned the classics, history, astronomy, geography, and medicine.
Best known in the medical tradition for assembling and prefacing the 敖氏傷寒金鏡錄 (KR3eb051, dated 至正元年 = 1341) — a recompilation and supplementation of the otherwise lost tongue-diagnostic series of Áo shì 敖氏. The work is the founding treatise of Chinese tongue-diagnostic literature and is therefore sometimes cited under his hào as Dù Qīngbì’s Jīn jìng lù 杜清碧金鏡錄.
