火車怪客 / Huo che guai ke

Her use of suspense and psychological insight is masterful. I'm curious about her writing process to build such a gripping mood.

The story makes you question what you'd do in their place. Did the moral ambiguity make the story more compelling or unsettling for others?

The premise feels so simple yet so sinister. I'm interested in whether this concept came from real events or was purely fictional imagination.
