《资治通鉴·汉纪·汉纪五十三》
袁绍本来很喜欢臧洪，想要使他屈服后，再加宽怒。见他言词激烈，知道决不会再为自己效力，就下令杀死臧洪。
绍本爱洪，意欲令屈服，原之；见洪辞切，知终不为己用，乃杀之。
Yuan Shao originally liked Zang Hong very much, and wanted to make him submit and then let him go. Seeing his fierce words, he knew that he would never work for him again, so he ordered to kill Zang Hong.
