Here's why:
* Third-person perspective: The story is told from a third-person perspective, meaning the narrator is not a character within the story. They are observing and narrating the events happening to the protagonist, Wang, from an external point of view.
* No personal involvement: The narrator doesn't express personal opinions or feelings, and doesn't participate in any of the actions happening in the story. They simply report the events, thoughts, and actions of the protagonist.
Therefore, the narrator is an objective observer rather than a character within the narrative.
