The Jiang Shi or Chinese Hopping Vampire is a Zombie subspecies found primarily in Asian countries such as China and Taiwan. Unlike standard Zombies, hopping vampires are severely affected by the symptoms of rigor mortis, making their joints, especially their elbows and knees, particularly stiff. Because of this, they must practice tai chi every morning to stretch. However, their joints always stiffen to some degree while they sleep, forcing them to hop around with their elbows and knees locked.
