Are there any ancestors of Hong Jun among Taoist immortals?

There is no Hong Jun in the Taoist immortal system.

Hong Jun was created in The Romance of the Gods. Taoist Hong Jun, also known as Hongjun's bodhi old zu, is called Taoist Hong Jun in the novel The Condor Heroes. He is the master of Taishang Laojun, Yuanshi Tianzun and Tian Tongzu.
