《智囊(选录)·明智部·范蠡》
长子一再请求前往，陶朱公不肯，长子认为父亲不派长子而派小弟，分明是认为自己不肖，想自杀。
长男固请行，不听。以公不遣长子而遣少弟， 是吾不肖 ，欲自杀。
The elder son repeatedly asked to go, but Taizhu Gong refused. The elder son thought his father did not send him while sending his younger brother, which obviously meant he thought he was not filial, so he wanted to commit suicide.
