《资治通鉴·周纪·周纪五》
朱亥立即从袖中掣出四十斤重的铁锥，打死晋鄙，魏无忌便部署军队，下令说： 父子两人都在军队中的，父亲可以回去！兄弟两人都在军队中的，哥哥可以回去！独子一个没有兄弟的，可以回去奉养父母！ 
硃亥袖四十斤铁椎，椎杀晋鄙，公子遂勒兵下令军中曰： 父子俱在军中者，父归；兄弟俱在军中者，兄归；独子无兄弟者，归养。 
Zhu Hai immediately pulled out an iron cone weighing 40 jin from his sleeve and killed Jin Bi. Wei Wuji then deployed his troops and ordered: "If a father and son are both in the army, the father can go back! If two brothers are both in the army, the older brother can go back! If there is only one son and no brothers, you can go back to support your parents!"
