放开了手才明白拥有时的贵落下了泪才知道心真的会疼
[fàng kāi le shŏu cái míng bái yōng yŏu shí de guì luò xià le lèi cái zhī dào xīn zhēn de huì téng]
'Only when letting go do we understand how precious it was when we had it; only when shedding tears did we realize the heart could truly ache.' Conveys regret after experiencing a loss, learning too late that things were precious and discovering emotions of pain afterwards.
