失去的东西别捡了太脏
[shī qù de dōng xī bié jiăn le tài zàng]
Literal translation would be 'Don’t pick up what you've lost; it’s too dirty.' It means once we've lost something or a person, it may bring unpleasant memories or troubles. Better let go and move forward without clinging onto the past which might be painful or tarnished by events.
