The Eight Immortals of Taoism widely circulated among the people. There were different views on the names of the Eight Immortals before the Ming Dynasty. There are eight immortals in Han Dynasty, eight immortals in Tang Dynasty and eight immortals in Song and Yuan Dynasties, and the listed immortals are different. Wu Yuantai's Journey to the East of Eight Immortals in Ming Dynasty is defined as Han Zhongli, Zhang, Cao Guojiu, Han Xiangzi, Lan Caihe and He Xiangu.

Legend has it that the Eight Immortals represent men, women, old people, young people, rich people, rich people, poor people and poor people respectively. Because all the Eight Immortals are ordinary people, their personalities are close to the people. Recently, they are very important representatives of immortals in Taoism. Many places in China have the Eight Immortals Palace, and the Eight Immortals are also essential places to worship God. As we all know, eight things held by the Eight Immortals, such as sandalwood boards, fans, crutches, flutes, swords, gourds, dusting and orchids, are "eight treasures" and represent the products of the Eight Immortals. Among literary and artistic works, the most famous is Eight Immortals Crossing the Ocean and Offering Birthdays. In today's Xi 'an, there is the Eight Immortals Palace (formerly known as the Eight Immortals Temple). Its main hall is the Eight Immortals Temple, which enshrines the statue of the Eight Immortals.
