Barefoot Immortal (Chinese: 赤腳大仙), also known as Barefoot Master, is a Taoist deity in Chinese religion.^[1] He is known for his numerous appearances in Chinese operas and Chinese ancient literature, such as Journey to the West and Outlaws of the Marsh. The ancient images and ceramic works that people found about the conception of the appearance of Barefoot Immortal demonstrate that in the minds of most people, Barefoot Immortal is a kind god who always has a gracious smile on his face. Never wearing any shoes and having a half bald head are his unique marks and looks. There are several stories and legends about Barefoot Immortal that have become the widely known classical folk oral literature in China. His original name was Liu Hai before he was widely known as Barefoot Immortal^[2] and Liu Cao.^[3]

According to the Journey to the West, one of the Four Great Classic literature Novels^[4] in China, Barefoot Immortal was shown to be an innocent god in heaven. There is a plot in this book that describes the story of how Monkey tricked Barefoot Immortal and then went to the Peach Banquet by using Barefoot Immortal's identity. One day the Monkey was pretty annoyed by knowing he was not on the invitation list and that no one had informed him of Peach Banquet which is a really important celebration in heaven. With a strong desire to go there, the Monkey soon came up with an idea. He met the Barefoot Immortal on his way to the Green Jade Pool. That is the place where Peach Banquet is held. He told Barefoot Immortal that every guest should go to the Hall of Bright Lights to go through a rehearsal before the banquet, and this is an order from the Jade Emperor. Even though Barefoot Immortal realized that this is not a tradition and he was kind of dubious about this message. But in the end, he still did what Monkey said and changed the destination without asking too many questions. After successfully deceiving the Barefoot Immortal, the Monkey changed himself into the appearance of Barefoot Immortal and headed to the Green Jade Pool Immediately. In the end, he totally ruined the entire banquet and made the Jade Emperor very angry. In this story, Barefoot Immortal was described as a naive god with an innocent heart but easily trusts the words from someone else which indirectly lead to the destruction of the Peach Banquet.

In Shaxian, Fujian, there is a legend about Barefoot Immortal.^[5] After Pangu created the world,^[6] one day Barefoot Immortal was on his way to the Green Jade Pool by riding his cloud. Suddenly his foot was knocked against the cliff of a mountain in Shaxian and that made him extremely painful and could not fly stably. The mountain was called Qingyun Feng (Chinese: 青云峰). He thought, even a god like him could get hurt by this strange and annoying cliff, what if it was a normal person passing by? Later, he decided to smooth this mountain up by plowing it with a god cattle that he borrowed from heaven to prevent people passing by from being hurt by its cliff.

However, the Mountain God did not agree with that decision, he was so scared that Barefoot Immortal will really destroy his mountain. Therefore, he came up with an idea to prevent it. He put a special insect on Barefoot Immortal's way that can make him fall asleep very quickly. Mountain God gave him a dream which told Barefoot Immortal that his mother has a serious illness and does not have many days left. If he did not come back to heaven right now, he might lose the chance to see his mother for the last time. Obviously, it is a lie. But after Barefoot Immortal woke up from this nightmare, he was so worried about his mother so he tied the god cattle to a tall pine tree and then came back to heaven. Mountain God successfully prevented Barefoot Immortal from plowing the cliff of his mountain. He asked Lei Gong and Dian Mu a favor to kill god cattle by hitting it with thunder and lightning, while the god cattle was carrying special spells that thunder and lightning they created could not hurt him even a little bit. Subsequently, the Mountain God borrowed a cymbal and a gong from a temple. He hit god cattle on the head with cymbal and gong when he was not looking. After Barefoot Immortal realized he was fooled by Mountain God, he came back to that mountain. However, at that time, the god cattle already killed by the Mountain God and he would never have any chance to plow this mountain anymore. In this legend, Barefoot Immortal showed his care and concern for people and his love for his mother in his character. He is a kind and filial god. He cared about people and he wanted to protect people so the idea of plowing the cliff up appeared to his mind. He also concerned about his mother. But, on the other hand, lack of enough wisdom made him fall into the traps of others and caused the death of god cattle. In the end, the Barefoot Immortal put the cymbal and gong on the top of that mountain with full of anger. After that, the name of that mountain was changed to " Cymbal and Gong Peak" (Chinese: 锣钹顶). As for that god cattle, it turned into a boulder and is still in Shaxian.

But when they got to there, they were so shocked by the terrifying and horrible views of that place. He found a mountain in front of him, there was a serious flood on the South side of the mountain. On the north side of the mountain, the pleasant scenery turned into a bare field with no grass and no plants.^[10]

They saw the Demon Dragon hurting this place deeply and getting pleasure by abusing local people.

Barefoot Immortal and the gods he invited to Si Kouzi have saved many living creatures' lives and brought a peaceful life back to this place. Moreover, the canyon that Barefoot Immortal kicked out had connected the two sides of the mountain which successfully let the flood flow into the arid bare field of another side of the mountain. Until now, the footprints that Barefoot Immortal left from kicking mountain remain there in Si Kouzi. .
