与其掏心掏肺到撕心裂肺不如狼心狗肺到没心没肺
[yŭ qí tāo xīn tāo fèi dào sī xīn liè fèi bù rú láng xīn gŏu fèi dào méi xīn méi fèi]
Means ‘rather than baring one’s soul until the pain becomes unbearable, it would better become ruthless like having a wolf heart and dog liver.' It illustrates a shift from deeply investing emotionally to deciding to no longer care about others’ feeling due to past hurt, opting instead for a coldhearted stance toward people or situations to prevent getting hurt again.
