Liu An
The Eight Immortals of Huainan (), also known as the Eight Gentlemen (八公 bāgōng), were the eight scholars under the patronage of Liu An (劉安 Liú Ān), the prince of Huainan during the Western Han Dynasty. They are not deified in any religions and the "xian" ("immortal") is used metaphorically to describe their talent. Together, they wrote the philosophical collection "Huainanzi" (淮南子, Huáinánzǐ, literally "The Philosophers of Huainan").
