Pen-name / spirit-medium attribution of an anonymous Qīng Buddhist-Daoist syncretic compiler, who signs his works as Fúyòu dìjūn 孚佑帝君 (“Imperial Lord of Faith-Protection”) — the YuánMíngQīng official Daoist title under which the legendary Táng immortal Lǚ Dòngbīn 呂洞賓 was canonized in the state pantheon. DILA explicitly notes: cǐ wéi yìzhě huàmíng, yǔ Lǚ Dòngbīn (Fúyòu dìjūn) fēi tóng yī rén 此為譯者化名，與呂洞賓（孚佑帝君）非同一人 (“this is a translator’s pen-name; not the same person as Lǚ Dòngbīn the Fúyòu dìjūn”).
Two works in the Xùzàngjīng are attributed to this pen-name: Jīngāng jīng zhùjiě (KR6c0091, X25 no. 503), prefaced Qiánlóng 1 / 2nd-month = 1736-03 / 04 under the alternate name Chúnyángzǐ 純陽子 (another Lǚ Dòngbīn appellation); and Bānruò xīnjīng zhùjiě (X26 no. 576). The texts are products of the early-Qián-lóng fújī 扶乩 / planchette-Daoist syncretic milieu, in which Buddhist sūtra commentaries could be produced under deity-attribution and circulated as immortal-revealed rather than human-authored.
