Early-Yuán Daoist scholar and commentator, hào Zhōngyángzǐ 中陽子, a dàoshi 道士 from Pénglái shān 蓬萊山 in Sichuan. Author of the monumental ten-juan Yùqīng wújí zǒngzhēn Wénchāng dàdòng xiānjīng zhù 玉清無極總真文昌大洞仙經註 (DZ 104, preface 1309, presented to the throne 1310) — the most philosophically ambitious Yuán-era commentary on [[KR5a0005|DZ 5 Wénchāng dàdòng xiānjīng]]. According to his preface, Wèi received the scripture as a youth and studied it for thirty years before producing this critical edition; he went to the capital to have it printed. The 1310 presentation was accompanied by prefaces from the thirty-eighth Celestial Master Zhāng Yǔcái 張與材, the Hànlín scholar Zhāng Zhòngshòu 張仲壽, and the academician Zhào Biàn 趙弁.
Wèi’s commentary combines a thorough knowledge of Shàngqīng and inner-alchemical Daoism with a solid classical training, using multiple interpretive systems and Neo-Confucian vocabulary to mount a deliberate defence of Daoism against Neo-Confucian attempts (e.g. by Zhū Xī) to marginalise it. Isabelle Robinet (Schipper & Verellen 2004, 2:708–710) characterises his commentary as “profound, multifaceted, and subtle,” and his technique as “brilliant.” No CBDB record was found.
