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 [[KR5a0316|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.
