梦回良人归梦醒凉城故
[mèng huí liáng rén guī mèng xĭng liáng chéng gù]
In English, it translates roughly to 'Dream of the Good Returning, Waking in the Cold City of the Past.' This evokes a sense of nostalgia and longing for a better past, a place or time that brings comfort when remembered. It also conveys melancholy and sadness over what might be lost.
