得到的时候你在毁失去的时候你再悔
[dé dào de shí hòu nĭ zài huĭ shī qù de shí hòu nĭ zài huĭ]
'When I had you, you destroyed it; when I lost you, you started regretting.' This phrase conveys mixed feelings of being undervalued during possession and seeing remorse after loss. A bittersweet feeling toward someone who didn't appreciate their presence until it was too late.
