Bǎi Hètíng 柏鶴亭 (fl. 1796–1797, Jiāqìng era), Qīng layman of Yángqū 陽曲 (eastern outskirts of Tàiyuán 太原, Shānxī) and convener of a planchette-circle (fújī tán 扶乩壇) of three at the western veranda of the office of the Yángqū wèi 陽曲尉 (Police-Commissioner of Yángqū). The circle’s principal product is the Shénxiān jǐshì liángfāng 神仙濟世良方 (KR3ed110) — a spirit-writing medical formulary in which the Eight Immortals (Lǚ Dòngbīn, Zhōnglí Quán, Zhāng Guǒlǎo, etc.), Shòuxīng (Pole-Star), and Lǐ Bái deliver prescriptions and verses through the planchette-frame. Compiled in late 1796 and early 1797. Sparse biographical information beyond the work’s prefaces; Bǎi is not recorded in CBDB or in the major Qīng biographical dictionaries.
