A person whose mouth is unforgiving has a kind heart, but a person whose heart is unforgiving has a sweet mouth. People with kind hearts dare to speak out, but people with sweet mouths hide secrets and cheats. It’s better to have a bunch of arrogant ghosts than a bunch of sweet-talking thieves

The knife has a mouth full of bean curd but the heart is sweet. People with a kind heart are usually very straightforward in their speech, while people who talk sweetly all the time are often very cunning in their hearts. I would rather make friends with an outspoken person who can make you mad even if he argues with you all day long, than with a sleazy person who always has honey on his lips but secretly plots against you in his heart.
