MOG WAI / MONSTER 魔鬼 (MÓ GUǏ)
In ancient stories, the moguai mating season was triggered by rain. So as just like the film “Gremlims” says --- don’t let them get wet.
There are a lot of shapeshifting beasts in Chinese legend. The Yaoguai (妖怪) are demons that eat souls to gain immortality. The shapeshifters would take on a different forms to trick their victims. A scary Chinese story tells the tale of a man who brings a beautiful maiden home. However, one night he spies on her through the bedroom window. Instead of seeing his beautiful girl, he sees a demon painting features on the skin of a woman.
