彩虹总会在暴风雨过后
[căi hóng zŏng huì zài bào fēng yŭ guò hòu]
Translated as 'After every dark cloud, there's a silver lining', it implies hope and optimism during hardships or trials, just like the rainbow appears after the storm ends. It reflects the philosophy or personal belief about life: bad days cannot stay forever, and good luck is expected at the end if one holds patience through difficult times
