Chang (creature)
The chang is a kind of ghost in ancient Chinese legend. According to the legends, people devoured by tigers turn into ghosts, who then help tigers devour other people. The idioms "s=为虎作伥" and "s=狼无狈不行，虎无伥不噬" arise from this.
It is described in the "Ma Zheng" chapter of the "Legend" quoted by Tang Peizheng in the Song Dynasty "Taiping Guang Ji".
Cantonese describes the chang as a wicked woman in the shape of a chicken; it is said that this allusion originated from Liu Jian.
