If you want to have fun and broaden your horizons, you can go to see stories like science fiction and fantasy.
If you want to improve your Chinese level and broaden your mind, I suggest you read some books such as essays and travel notes. After all, those books will deepen your thinking and enable you to appreciate those fantasy novels.
Look at the authors in fantasy novel, not necessarily how many books they have to read, but that they are influenced by language, so that they can have enough linguistic logic to arrange those unconstrained things.
Therefore, healthy and beneficial books can be read, not too limited and fixed in thinking.
