Jiangshi refers to a specific type of undead creature from Chinese folklore, often translated as a "hopping vampire" or "hopping corpse."
The word 僵尸 (jiāngshī) literally means "stiff corpse." A jiangshi is a reanimated corpse that moves by hopping with its arms stretched out, often dressed in the robes of a Qing dynasty official.
Key Difference from Zombies: While Western zombies are typically mindless, rotting creatures driven by a hunger for brains, a jiangshi's behavior is more like a vampire. It sucks the life force ("qi") out of living people, and it can be warded off using Taoist talismans, mirrors, or specific types of rice.
