Science fiction: Explores the relationship between humans and technology with the theme of the future or fictional technology. 2. Fantasy novels: They use myths, legends, and magic as the main theme to describe the relationship between humans and magic. 3.

Science fiction/fantasy novels: stories about how humans use these elements with a certain technology or magic theme. 5. Wuxia novels: The story of heroes with the theme of martial arts and Jianghu. These types of novels had their own unique characteristics and word count requirements.
