咖啡不解酒的醉白天不懂夜的黑
[kā fēi bù jiĕ jiŭ de zuì bái tiān bù dŏng yè de hēi]
Translates into 'Coffee cannot alleviate drunkenness from alcohol just as daytime doesn’t understand nighttime’. Refers metaphorically to situations where opposites struggle comprehending each other, possibly hinting at different perspectives or lifestyles.
