What poems describe the ugliness of human nature?

Flowers bloom regardless of family poverty, and the moon shines everywhere.

Only people in the world are evil, and everything must be nurtured by heaven.

Blind, deaf, dumb, rich, intelligent, but poor.

It should be set at the time of year, month and day, not by people to calculate the reason.

Easy to rise and retreat, easy to reverse and easy to save people's hearts.

The sea is shallow and the villain is deep.

People have ulterior motives.

Most of the above comes from (Water Margin)

It should mean reflecting human nature and the world. People's hearts are sinister and difficult to manage. You must pray to God for help.
