发霉情书短暂情话
[fā méi qíng shū duăn zàn qíng huà]
'Moldy Love Letters Short-lived Sweet Words.' The expression conveys disillusionment with fleeting romantic gestures or words. Love letters are supposed to preserve romance across time, but once they're dampened or aged (figuratively 'moldy'), they seem to lose sincerity and duration, representing disappointment with impermanence or superficial expressions of love.
