The Jin dynasty historian Sun Sheng compared Ma Chao's betrayal of his father Ma Teng to other historical examples of extreme cruelty and inhumaneness, including: the conflict between the Zhou dynasty and the vassal state of Zheng in 720 BCE; in 203 BCE, after Xiang Yu captured Liu Bang's father and threatened to boil him alive if Liu Bang did not surrender, Liu Bang asked Xiang Yu to share a bowl of his father's flesh with him.
