Science fiction: a fictional literary work that mainly describes the influence of imaginary science or technology on society or individuals.

Fantasy novel: It is a literary form, and the word fantasy is translated from the English word "fantasy". This translation was fixed by 1992 when Zhu, the head of Taiwan Province Fantasy Culture and Art Foundation, set up a * * * one-and-a-half-year "Fantasy Library" column in Software World, an old monthly magazine in Taiwan Province Province, and has since become a common translation. The difference between fantasy novel and science fiction lies in that they are usually biased towards the non-100% rational or unpredictable world structure (including magic, sword, gods, demons and prophets), and they are distinguished in chronological order. Fantasy novel is inclined to the past, that is, looking for background or similarity in history, while science fiction tends to continue the existing technology and strengthen imagination.

Magic novel: that is, "magic realistic novel" is a literary genre mainly appearing in Latin America. Magic novels are by no means "magic", but have a completely different definition, which is far from what most people imagine. This magical novel genre combines shocking reality with trance-like illusion, uses extreme exaggeration and artistic brushstrokes of reality and fiction to trap people and weave plots in an attempt to describe and reflect complex historical, social and political phenomena.
