In Malay belief, a woman who dies in childbirth will become a langsuir. These demonic beings have holes in the back of their neck through which they suck children's blood. The langsuir are dressed in green robes, have long nails, and long, jet-black hair.
There are special rites for women who die in childbirth: glass beads are put in their mouths, needles in the palms of their hands, and eggs are placed in each armpit. This prevents them from becoming a langsuir.
