When the policy is plain, people are contented and chaste.
When the policy is strict, people are destitute and sullied.
Misfortune can gestate fortune; fortune can evolve into misfortune.
Who knows the evolvement law? There is no predefined rule.
The integrity can be strange; the charitableness can be foul.
The puzzlement of people exists for a long time.
Therefore, the saint should be upright not isolated, plain not crude, straightforward not hurtful, and shining not glaring.
