《明史·列传·卷十二》
值酒酣之时，陈友定当众发誓说 ：我们大家同受元朝厚恩，若有不以死拒敌者，将受磔刑，并杀其妻儿。 
酒酣，誓于众曰： 吾曹并受元厚恩，有不以死拒者，身磔，妻子戮。 
When the drinking became intense, Chen Youding swore in front of everyone that, "We have all received great kindness from the Yuan, and anyone who does not fight to the death against the enemy will be punished with execution, and his wife and children will be killed."
