Lü Dongbin
The "Zhong Lü Chuan Dao Ji" ( "Anthology of the Transmission of the Dao from Zhong[li Quan] to Lü [Dongbin]") is associated with Zhongli Quan (2nd century CE?) and Lü Dongbin (9th century CE), two of the legendary Eight Immortals. It is part of the so-called “Zhong-Lü” () textual tradition of internal alchemy ("neidan"). Komjathy describes it as, "Probably dating from the late Tang (618–906), the text is in question-and-answer format, containing a dialogue between Lü and his teacher Zhongli on aspects of alchemical terminology and methods."
