What Is Transmigration?

Transmigration means a character’s soul travels into another body — usually in a different world, time period, or even inside a novel they once read.

If you know Isekai (Japanese portal fantasy), transmigration is the Chinese version — but with its own twists.

Common Transmigration Setups

Into a novel: The protagonist knows the plot because they read the novel in their past life
Into a game: They enter a game world (often with a system)
Into history: They travel to ancient China (sometimes with modern knowledge)
Into a villain’s body: The protagonist is now the villain and has to survive

Transmigration vs. Reincarnation

	Transmigration	Reincarnation
Body	Enters someone else’s body	Reborn as a baby (new body)
Memory	Usually keeps past-life memory	Keeps past-life memory
Plot knowledge	Often knows the future (if transmigrated into a novel)	May or may not know the future

Why Readers Love It

The “Villain Protagonist” Trope

A very popular sub-trope: the protagonist transmigrates into the villain of a novel. They have to:

Avoid the original “death flag” (the event that killed the villain)
Change the plot without making it too obvious
Sometimes befriend the original “hero”

FAQ

Is transmigration always to another world? No — sometimes it’s time travel within the same world (e.g., modern person goes back to 1990s China).

Do they keep their original appearance? Usually no — they’re in a new body. Part of the story is adapting to the new face, gender, or social status.

Is this the same as “Chuan Shu” in Chinese? Yes! 穿书 (chuanshu) literally means “pass through a book” — entering a book’s world.
