Jiang Shi are basically the Chinese equivalent of a Zombie, but like ten times cooler. So supposedly they were first created by Taoist practicioners who needed to transport dead bodies back to their homes so they could be buried in their family graveyards. And instead of carrying them, they reanimated the bodies instead and had them hop back to where they needed to be. Also, some of them went rogue and became vampires?!? Like, they can suck out your life force?! Ancient Chinese people were wild.
