Yáo Hé 姚合 (781–846), great-grandson of the great early-Tang chief minister Yáo Chóng 姚崇 (650–721), was jìnshì of Yuánhé 11 (816). He began his career as Wǔgōng zhǔbù (subprefect of Wǔgōng), where his Wǔgōng xiàn 30-poem set established his early reputation — hence the persistent nickname Yáo Wǔgōng and the so-called Wǔgōng tǐ 武功體 (“Wǔgōng style”) of austere late-Táng kǔyín verse. He subsequently held Fùpíng and Wànnián sub-prefectships; in Bǎoyìng (763 — but here meaning Bǎolì 825–826?): jiānchá and diànzhōng yùshǐ, Hùbù yuánwàiláng; out as Jīngzhōu and Hángzhōu prefect; later Hùbù lángzhōng, Xíngbù lángzhōng, Jiànyì dàifū, ShǎnGuó guāncháshǐ; ended Kāichéng end as Mìshū shǎojiàn (Vice-Director of the Imperial Library) — hence the title Yáo Shǎojiàn of his collection.
Yáo’s verse, alongside that of Jiǎ Dǎo 賈島, is the canonical mid-/late-Táng kǔyín paradigm. Beyond his own verse, Yáo is also remembered as the editor of the Jí xuán jí 極玄集 — a major late-Táng anthology of his own contemporaries’ work, separately catalogued in KR4h. The Southern-Sòng Yǒngjiā sìlíng (Xú Zhào, Xú Jǐ, Wēng Juàn, Zhào Shīxiù) explicitly took Jiǎ Dǎo and Yáo Hé as their poetic ancestors.
