夏了夏了夏天秋了秋了秋天
[xià le xià le xià tiān qiū le qiū le qiū tiān]
'Summer went by, and here we are again, autumn comes'. A poetic phrase marking the cyclic nature of seasons changing over time. It captures a bittersweet acknowledgment of fleeting moments and the passing of the years which evokes feelings of both fondness for warm summertime memories, and longing or nostalgia when transitioning into another season.
