回头不可改变的结局
[huí tóu bù kĕ găi biàn de jié jú]
'Cannot Change The Consequence By Turning Back.' A reflection of the belief that certain destinies cannot be changed by going back in time or retracing past decisions. This expresses a feeling where outcomes or life changes have led the person on an unalterable path, accepting what lies ahead without any regret or longing to undo things done earlier.
