Yáng Yínqiū 楊寅秋 (late 16th c., active Wànlì), zì Yìshū 義叔, hào Lín’gāo 臨臯, of Lúlíng 廬陵 (Jízhōu, Jiāngxī). A great-grandson of Yáng Shìqí 楊士奇 KR4e0007. Rose through provincial postings to Guǎngxī Zuǒjiāng bīngbèidào fùshǐ. He participated in the major late-Wàn-lì southwest-frontier campaigns: pacification of the Dāgàn miáo; suppression and execution of the Yúnnán tǔyí Pǔ Yìngchūn; capture of Wǔshān; pacification of the Ānnán Dìngfǔ jiāng; and as Zuǒ jiānjūn in the 1600 Yáng Yìnglóng (Bōzhōu) campaign — one of the three great Wànlì SānZhēng (Three Campaigns). The Sìkù tíyào dates his jìnshì to Jiājìng 5 (1526, bǐngxū), which is incompatible with his 1600 active military service and almost certainly a typographical slip for a Wànlì year. His collection is the Língāo wénjí KR4e0221. CBDB 34740 has zero markers.
