哭着要不回那些快乐
[kū zhe yào bù huí nèi xiē kuài lè]
'Crying Cannot Bring Back That Happiness' conveys the deep regret of a person mourning over what could have been happier moments that can never be recovered. Someone with this nickname might be reflecting nostalgically on lost times full of cheer, now just bitter memories requiring much courage and peace to let go.
