狼心狗肺好过撕心裂肺
[láng xīn gŏu fèi hăo guò sī xīn liè fèi]
‘Better to Have a Heartless Soul than to Tear One’s Own Heart Apart’ compares having no conscience (implied by 'wolf heart' and 'dog lung', meaning being ruthless) to enduring immense emotional pain ('ripping one's heart'). It suggests preferring hardness over vulnerability and emotional suffering.
