Fàn Yíbīn 范宜賓 (b. 1710; CBDB index year 1710), hào Yīzhōngzǐ 一中子, native of Shěnyáng 瀋陽 (Liáoníng) — mid-Qīng Lóngmén Daoist scholar. His Yīnfú xuánjiě 陰符玄解 (KR5i0033) is dated Qiánlóng rénchén mid-summer, the day of the full moon (= 5 July 1772), composed at his Zhígǔ Xuān 執古軒 study. The self-preface narrates that as a young man (the bǐngzǐ year, 1696 or 1756 — most plausibly 1756 if Fàn was born 1710) he had asked his teacher Sōngshān xiān shēng 嵩山先生 about the Yīnfú jīng, who described it as “an out-of-the-world book — the founding text of the Three Teachings and the Hundred Schools, the formula of yuánshǐ făn-zhōng (returning-to-original-end), the marvellous formula of stealing-and-snatching, the supreme-vehicle’s subtle beauty,” and transmitted to him the lineage of Èrwǔ dàorén 二五道人. Fàn’s nephew Bǎoxiáng 寶祥, returning from Sichuan, brought him a manuscript of the Yīnfú fāmì 陰符發祕 by Zhāng Qīngyè 張清夜 (alias 自牧道人), abbot of the Zǐyáng Cavern in Chéngdū; his own Xuánjiě is the matching extension of Zhāng’s earlier commentary. Fàn was thus a lay Lóngmén scholar networked across Liáoníng / Sìchuān, with strong contacts in the Chéngdū DZJY-source community. CBDB ID 61219.
