Southern-Sòng nèidān 內丹 transmitter, hào Zǐyáng wēng 紫陽翁 (“the Old Man of Zǐyáng”) — a contemporary of Wēng Bǎoguāng 翁葆光. According to the standard WēngChénBóyúnzǐ lineage account preserved in [[KR5a0142|DZ 141 Zǐyáng zhēnrén Wùzhēn piān zhùshū]] and the appendix [[KR5a0144|DZ 143 Sānchéng bìyào]], Chén Dálíng received the Wēng commentary on Zhāng Bóduān 張伯端’s Wùzhēn piān 悟真篇 directly from Wēng and transmitted it to his disciple Bóyúnzǐ 白雲子, who in turn produced the preface dated 1204 (Jiātài jiǎzǐ 嘉泰甲子). Chén’s own preface to the Wēng-commentary (preserved in DZ 141) maintains, against the testimony of others, that Wēng had received his edition from Liú Yǒngnián 劉永年; this assertion appears to attach Wēng’s transmission to a line distinct from the original Lù-family transmission of Zhāng Bóduān.
