Chinese Proverbs: A word from within
Chinese proverbs and four and more characters in idioms are
developed from the formulaic or social dialect, saying, expression and
historical story in Chinese. Some proverbs are literary, that is,
from a written source
Man who live in glass house should change clothes in
basement.
Man who fish in other man's well often catch crabs.
A fall into a ditch makes you wiser.
Have a mouth as sharp as a dagger but a heart as soft as tofu
If you have never done anything evil, you should not be worrying about devils to knock at your door.
