Liú Dàbīn 劉大彬, the forty-fifth patriarch (zōngshī 宗師) of the Máoshān 茅山 Shàngqīng 上清 lineage in the Yuán dynasty, compiler of the Máoshān zhì 茅山志 (DZ 304). According to the imperial edicts preserved in the work’s frontmatter, in Huángqìng 皇慶 1 (1312) — the Huángqìng gǎiyuán 皇慶改元 of the preface — he was given the canonical title Dòngguān wēimiào xuányīng zhēnrén 洞觀微妙玄應真人 (“Zhēnrén of Cavern-Insight, Subtle Marvel, and Profound Response”). Five years later (1317), the canonisation was extended: the three Máo brothers received augmented titles (Zhēnyīng 真應, Miàoyīng 妙應, Shényīng 神應), and the three peaks of Máoshān were reconstituted as observatories — Shèngyòu 聖祐, Déyòu 德祐, Rényòu 仁祐. Liú had been brought to imperial attention by Wú Quánjié 吳全節 — the Xuánjiào dà zōngshī 玄教大宗師 (1269–1346) — who had first approached the forty-fourth Máoshān patriarch Wáng Dàomèng 王道孟 and, finally, his successor Liú. Liú entrusted his disciples with collecting material for the chronicle of Máoshān; the work took thirteen years to complete, with successive supplements being added (the latest being a memorandum on a jīnlù zhāi 金籙齋 held in 1330 on behalf of the empire, at 4.18b–19a). His personal lifedates are not known. CBDB lists him at c_personid 111121 (Yuán) without dates.
