The most basic feature of romantic literature is to express ideals and wishes in a passionate and exaggerated way.
Romantic literature emphasizes imagination to express ideals and hopes, nature to express personal subjective feelings and emotions, and symbols and myths to highlight literary metaphor, expressiveness, exaggeration and peculiar artistic expression. These characteristics are the characteristics of romantic literature.
Romantic literature has the characteristics of bold fantasy, strange conception and exaggerated technique in expression.
Just like Li Bai's: White Hair and Three thousands of feet, the technique is exaggerated but artistic.
