If we say older novels, the works of Defoe, Swift, Fielding, Dickens and Thackeray can also be considered, for fear that too many people will write the same novels.

If we say modernist novels, we should learn from Kafka (Czech expressionism) and James (Irish stream of consciousness) for Heller (American black humor) and Sartre (French existentialism). Among them, Variations is a good work and easy to spread (if cross-border writing is allowed). Go to see the lighthouse, rainbow, etc.

If we say that contemporary novels are too diversified, the materials can be widely used, and the theme is difficult to restore, so it is not recommended.
