A cat may look at a king.人人平等.
Actions speak louder than words事实胜于雄辩.
Adversity leads to prosperity.穷则思变.
Adversity makes a man wise,not rich.逆境出人才.
A fair death honors the whole life.死得其所,流芳百世.
A faithful friend is hard to find.知音难觅.
A fall into a pit,a gain in your wit.吃一堑,长一智.
A fox may grow gray,but never good.江山易改,本性难移
