这个夏天说再见
[zhè gè xià tiān shuō zài jiàn]
'Saying goodbye this summer' evokes the bittersweet mood accompanying end-of-season farewells. Summers are synonymous with freedom and carefree memories; hence this nickname captures the nostalgia and melancholy associated with endings tied specifically to the summertime, perhaps bidding adieu to youth, love, or significant changes.
