Are the "Eight Immortals" in history eight immortals? Are they mortal?

Yeah ~ ~ Don't you know the Eight Immortals?

Although these eight people have a high rank and are the Eight Immortals, they can occasionally meet the leaders, but they have no real power and are idle people, but they are indispensable at every banquet. Just like our Democrats, they are idle. In the whole heaven, the only thing they are afraid of is the queen mother. They can embarrass the jade emperor, but the queen mother can't afford to offend anyone. She is very hard on others. Once you put on these little shoes, it's hard to take them off.

The Eight Immortals are the Eight Immortals enshrined in Taoism and widely circulated among the people, including, Zhang, Li Tie, He Xiangu, Lan Caihe, Han Xiangzi and Cao Guojiu. The Taoist theory of the Eight Immortals can be traced back to the Song and Yuan Dynasties. In the Yuan Dynasty, the Yueyang Tower in Ma Zhiyuan, the bamboo boat in Fan Zi 'an and the willow in the south of Gu all had eight immortals, similar to those handed down from this world. In the middle of Ming Dynasty, after the publication of Wu Yuantai's Travel Notes of the Eight Immortals in the East, the Eight Immortals that have been circulated in this world were finalized.

Han Zhong, a reincarnated Taoist priest, was seen from Zhang riding backwards on a donkey.

Lv Dongbin dreamed that He Xiangu's servant girl Lan Caihe begged for the Song Dynasty, and Han Xiangzi Lan Guandu Shu Cao Guojiu lived on a secluded rock.
