Zhāng Qīngyè 張清夜 (1676–1763), hào Zìmù dàorén 自牧道人 (“Master Tend-Yourself”) — one of the most consequential figures of mid-Qīng Sìchuān Daoism, abbot of the 紫陽洞 Zǐyáng Cavern at Chéngdū / Méngshān, and a chief reorganiser of the Chéngdū Lóngmén Quánzhēn establishment in the Yōngzhèng / Qiánlóng era. Famed for the Yīn fú fā mì 陰符發秘 — a major Yīn fú jīng commentary in the inner-alchemical and Nángōng arts — and for laying down the institutional framework of Sìchuān Quánzhēn temples that would later be the matrix for Hé Lóngxiāng’s 1906 Dào zàng jí yào expansion. He is mentioned by Fàn Yíbīn as already deceased (“已尸解而去”) at the time of Fàn’s 1772 preface (cf. KR5i0033).
