Lǚqiū Yìn 閭丘胤
Legendary mid-to-late-Táng provincial official traditionally credited with collecting and prefacing the Hánshānzǐ shī jí 寒山子詩集 KR6q0188. The preface-title identifies him as Cháoyì dàfū shǐ chíjié Táizhōu zhū jūnshì shǒu cìshǐ shàngzhùguó cì fēi yúdài 朝議大夫使持節台州諸軍事守剌史上柱國賜緋魚袋 — a senior provincial military-administrative prefecture governor of Táizhōu.
The historicity of Lǚqiū Yìn is doubted by modern scholarship: neither the Táng dynastic histories nor the Táng-era tomb-inscription corpus confirm his existence, and the preface itself contains narrative elements (the Fēng-gān-Hánshān-Shídé recognition as Mañjuśrī-Samantabhadra, Hánshān’s sealed-cave withdrawal, etc.) that are structurally legendary. The preface and the preface-attribution are now generally regarded as pseudepigraphical constructions, possibly composed as late as the late-Táng or early-Sòng to establish the Hánshān poetic corpus within a legendary-hagiographic frame.
Regardless of historicity, the preface is an important document of the Hánshān legend (the trio of Hánshān, Shídé, and Fēng-gān at Tiāntái-shān’s Guóqīng-sì, with their attribution as Mañjuśrī-Samantabhadra-Amitābha incarnations) and has been the principal vehicle through which the Hánshān narrative has been transmitted into subsequent Chinese, Japanese, Korean, and (since the mid-20th century) Western Buddhist literary culture.
