Based on the theory of entropy concerned with all types of disordered managements, this paper analyze the problems faced by the protagonist and the other characters. It discusses the characters’ efforts of overcoming the increase of entropy and their state of being restricted by authoritarianism through the political instruments, and examines different kinds of entropy under relative factors — Entropy under the creation of nothingness, entropy under the control of thoughts and the deprivation of emotion.
