《韩非子·难四》
所以公子目夷让出君位，而楚国商臣却逼死父王；郑公子去疾把君位让给弟弟，而鲁桓公杀掉哥哥自当国君。
故公子目夷辞宋，而楚商臣弑父；郑去疾予弟，而鲁桓弑兄。
Consequently, Master Mu Yi yielded his kingship while Shang Chen of Chu forced his father king to death; Zheng’s Master Qu Ji yielded to his younger brother while Duke Huan of Lu killed his older brother and reigned the country himself.
