Wǔ Shǒuyáng 伍守陽 (1573–1644 trad.), hào Chōngxū zǐ 沖虛子 / Chōngxū zhēnrén 沖虛真人 — late-Míng Lóngmén Daoist of Jiāngxī, foundational figure of the so-called WǔLiǔ pài 伍柳派 of inner alchemy. Of Yùshān 玉山 origin, he transmitted the Tiānxiān zhènglǐ 天仙正理 (KR5i0067) — completed in Tiānqǐ rénxū (1622) and revised through 1639 — and the Xiān fó hé zōng yǔ lù 仙佛合宗語錄 (KR5i0066), both of them principal mid-Lóng-mén systematic nèidān texts. His brother Wǔ Shǒuxū 伍守虛 (hào Zhēnyángzǐ 真陽子) acted as collator. The lineage continues through Wǔ’s pupil Liǔ Huáyáng 柳華陽 (1735–?), giving the school its compound name WǔLiǔ. The WǔLiǔ tradition’s clear stage-by-stage exposition of inner alchemy made it the most widely-circulated nèidān doctrine of the late-Qīng / Republican era, fed into the late-Qīng “Daoist Yoga” literature, and underlies the modern systematic accounts.
