Jiǎ Míng 賈銘 (hào Huáshān lǎorén 華山老人, 1269–1374; CBDB 29607), one of the most remarkable figures of the YuánMíng transition by virtue of his canonical 106-year lifespan: born late in the Southern Sòng, he lived through the entire Yuán dynasty and into the early Ming, dying in Hóngwǔ 7 = 1374.
His sole transmitted work is the Yǐnshí xūzhī 飲食須知 (KR3eo044) — the principal Yuán-era systematic compendium of dietary contraindications, 8 juan. Late-imperial popular tradition has it that the Hóngwǔ emperor (founding Ming emperor, r. 1368–1398) summoned the centenarian Jiǎ to court to inquire the secret of his longevity, to which Jiǎ allegedly replied that he had simply followed his own dietary rules — though the historicity of this anecdote is uncertain.
CBDB 29607 records his dates as 1269–1374; principal reference WDY 3, p. 1631. The pseudonym Huáshān lǎorén signals a Western-Mountain (Huáshān, in Shǎnxī) Daoist retreat-affiliation. No further biographical detail recoverable.
