曾经的幸福一败涂地曾经的挚爱无可挽留
[céng jīng de xìng fú yī bài tú dì céng jīng de zhì ài wú kĕ wăn liú]
'Past happiness lies in ruins and lost love cannot be retained' shows strong regret and sorrow over broken relationships and lost love. There’s deep pain conveyed about unrepairable situations in one’s past life.
