The Monkey King is made of stone. He has no parents and has never been with anyone in his life, which shows that he is a "lonely hero". According to psychoanalysis, lonely heroes reflect the mentality of school-age children. I think everything is the same as people, with thoughts, feelings, walking and talking. From the perspective of cultural development, stone worship precedes totem worship. The earliest objects that humans worship are inanimate objects such as stones, then plants and animals, and finally people themselves. The worship of animals leads to the emergence of totems, and the worship of oneself leads to the emergence of immortals and superhuman beings in the modern sense. However, high-level worship forms always contain low-level worship forms, and there are still primitive worship contents in modern people's minds. Therefore, modern people still have deep feelings for stones, which are reflected in the collection of strange stones, stone carvings, wearing jade diamonds, and imagining natural rocks as human animals, such as the couple peak in Yandang Mountain and Ashima in Shilin. Jung believes that stones are more primitive than plants and animals, so they are closer to the collective unconscious, more prototype and more reflective of themselves.
