A murderous monkey creature from Chinese lore, they are said to reside in Western China. They can assume human shape, are good runners, and will chase humans. They ambush female travelers and kidnap the beauties by their smell. Having captured a woman who will be their wife, the Jueyuan builds a home for her. Should she not bear a son she is forced to stay with her captor for good and after 10 years her shape becomes like his, with her no longer thinking of home. If she has a child, she is sent home immediately. If she refuses to have a child she is killed. The child looks no different than an ordinary human.
