In Fuka's Metamorphosis, due to the heavy physical and mental oppression, people lost their essence and became inhuman. It describes this sense of loneliness and strangeness between people, that is, between people, competition intensifies, feelings fade, and relations deteriorate, that is, this relationship is absurd and difficult to communicate. The salesman woke up and found himself a beetle. Although it still has people's emotions and psychology, the shape of the bug gradually turned him into another kind, which was abandoned by the world after deformation and was extremely sad. After three failed attempts to contact relatives and the outside world, only death awaited him. It seems that his deformation reflects the real life state of westerners at that time. Kafka didn't just explain the facts through novels, but rebelled against the world and pursued the perfection of human nature.

Kafka's novels are the perfect combination of dreams and reality. There is both the most sober examination of the modern world and the craziest imagination. "So if we think of similar things in real life, when our own existence is determined by some unpredictable and inevitable circumstances, and the absurdity of life is closely related to the absurdity of this story, then the problem before us is sharp: when we suddenly can't move, we are completely powerless, and we lose all human autonomy, what should we do? Kafka's novels bring us deep doubts. Obviously, in such an absurd mutation, Kafka was keenly aware of some essential problems in real life before using this symbolic, exaggerated and even absurd method to express it.
