Fish Gills (鱼鳃) is not a ghost in the way you think. He is a soul-warden of all aquatic creatures, a drowned fisherman who became the administrative gatekeeper between water and the Underworld—a being who belongs to no realm, yet commands the passage of every finned and shelled soul from the riverbed to the cycle of rebirth.

Story context
Let’s start with a moment that probably isn’t in any of the old stories. A fisherman drowns. Not a poetic, dramatic drowning—just a cold, tiring, panicked one at the bottom of a river he knew all his life. And then his soul tries to leave, but it can’t. The water holds him. And for three years, he just sits there in the mud, slowly becoming less of a man and more of a *place*. Now, when you imagine a ghost, you probably think of something that haunts an old house or a graveyard. But imagine being haunted by an entire river. That’s the first thing you need to know about the soul-warden called Fish Gills.
Why it matters
If you’ve spent any time with Chinese ghost lore, you might have heard of Fish Gills. He shows up in a few old texts—the *Soushen Ji* mentions him, and so does the *Journey to the West*—usually as a minor figure who manages the souls of fish and turtles. In pop culture, he’s sometimes given a comedic role, a kind of harmless water-bureaucrat. But the truth about him is much stranger. He’s not a joke. He’s a rare, deliberate creation of the Underworld: a ghost who was deliberately *not* forced into reincarnation, because the system needed someone who could speak to the dead of the water. He’s not a monster. He’s a function—but a function made from a drowned man’s soul.
