心中有座坟住着未亡人
[xīn zhōng yŏu zuò fén zhù zhe wèi wáng rén]
This phrase, literally translating to 'there’s a grave in my heart living in which is one not quite dead,' is highly metaphorical and emotionally profound, signifying the heavy grief or loss the person carries inside, where a deeply mourned being (figurative) lives on but only barely.
