Here are to evaluate people:
If they are in positions of high status, observe what they promote.
If they are wealthy, observe what they give.
If they are poor, observe what they refuse to accept.
If they are of low status, observe what they refuse to do.
If they are covetous, observe what they will not take.
See them change difficulties, and you can know their courage.
Move them with joy and happiness, and you can observe their self-control.
Entrust them with goods and money, and you can assess their humanity.
Shake them with fear, and you can know their discipline.
