It was under such circumstances that he became dissatisfied with and rebellious to the feudal officials and social indifference.

There are varieties of immortals and monsters in the stories, which represent justice and evil. The author has created a mythical world in this book, which is also a reflection of the human's. The heavenly palace looks grandiose from the outside, but the God is fatuous and cannot tell good from bad, which resembles the imperial palace of the human world. In the chthonic world that may represent the human royal courts, officials are corrupted, and the innocent people received undeserved treatment. As to the monsters and devils, they kill and eat people, avaricious and concupiscent. They use their witchcrafts to harm people. It is no doubt the reflection of local tyrants and bureaucracy. In contrary to those demons, Monkey King, the hero of the novel, has intense animosity or hostility to the evil.
