Liu Kai (947-1000) was born at Daming in modern southernmost Hebei. He was known to be a highly accomplished scholar as well as a ruthless commander. Jiang Shaoyu (fl. 1115-1145) accused him of cannibalism and eating the minced livers of human beings, but this is likely a literary expression meant to evoke imagery of savageness rather than something to be taken literally.
