Early-Yuán 元 Daoist scholar, active c. 1312. Author of the commentary on the Cháng qīng jìng jīng 常清靜經 preserved as DZ 757, published under a pseudo-Bái Yùchán 白玉蟾 (葛長庚) attribution.
Activity. 1312 (attested). No lifedates or other biographical details recorded. No CBDB record identified.
Lineage. Evidently associated with the Southern Lineage (Nán zōng 南宗) nèi dān 內丹 tradition — the DZ 757 commentary bears the distinctive stamp of Zhāng Bóduān-lineage inner-alchemical vocabulary, and its pseudo-attribution to Bái Yùchán (the fifth Southern-Lineage patriarch) places Wáng Yuánhuī firmly within that tradition.
Work. His sole attested work is DZ 757 — a commentary on the Cháng qīng jìng jīng dated 1312.
