心中有座城城里住着疼
        
            [xīn zhōng yŏu zuò chéng chéng lĭ zhù zhe téng]
        
        
            Translates as 'There's a city inside my heart and in that city lives the hurt/pain'. It represents inner agony or trauma kept deeply within one’s self, much like a secluded and untouchable place where one harbors their sorrow.
