Ju Liusun ,disciple of same generation as Guang Chengzi and Randeng .. one of Yuqing's noted disciples .(Yuqing is Jade pure one aka primeval lord of Heaven if anyone forgot) . His presence in the myths are obscured at best ,but he was involved in the accident regarding the Ruyi and Qiankun . One of the 12 daoist immortals . .the 12 Golden immortals of Chan School .

I'll settle for the bit of lore from our daoist brother
