咖啡不解酒的醉白昼不懂夜的黑
[kā fēi bù jiĕ jiŭ de zuì bái zhòu bù dŏng yè de hēi]
Coffee Cannot Sober Up Wine and Daylight Doesn’t Understand the Darkness of Night. Uses metaphors comparing different states or experiences that aren't mutually understood, perhaps implying certain contrasts or complexities in life’s experiences.
