城毁心已亡
[chéng huĭ xīn yĭ wáng]
'城毁心已亡', literally 'The city is destroyed and the heart dies', reflects a profound emotional state of despair or heartbreak paralleled with the destruction of a fortress or city. It illustrates that after going through tremendous trauma or devastation, not just physical objects get demolished but even the inner peace or willpower also vanishes.
