The most difficult thing in life is to know yourself.
The greatest victory is to defeat yourself.
If you want to know yourself, you'd better ask someone else.
If you can't direct yourself, you can't direct others.
The most flexible people can't see their backs.
The more incompetent people are, the more they like to find fault with others.
Washing one's heart to remove evil is like bathing one's body to remove dirt.
The stars in the sky can be counted clearly, but the soot on his face can not be seen.
Only in the middle of the crowd can we know ourselves.
It is never too late to correct mistakes.
If you don't evaluate yourself, you won't judge others.
Introspection is the way to virtue and God.
My shoes, I know where they are tight.
Those who are afraid of you in front of you must hate you behind your back.
I know how much I eat.
Don't laugh at other people's hunchbacks. Keep your waist straight.
Everyone knows where the shoe pinches.
