没有体温没有心才叫做痛
        
            [méi yŏu tĭ wēn méi yŏu xīn cái jiào zuò tòng]
        
        
            'Only without body heat or heart do you feel pain', it means true agony comes when one is emotionally deadened inside due to losing passion and energy - indicating profound pain through lack of sensation, rather than experiencing overt emotional pain.
