某年某月某日晴同年同月同日阴
[mŏu nián mŏu yuè mŏu rì qíng tóng nián tóng yuè tóng rì yīn]
It translates to 'one day was sunny and another same-date day was cloudy.' This could imply changes over similar circumstances or times - suggesting impermanence and how things can change unexpectedly but follow patterns, highlighting duality and transformation in one’s life journey.
