空城空旧梦凉城凉人心
[kōng chéng kōng jiù mèng liáng chéng liáng rén xīn]
Combining elements of loneliness and disillusionment. Refers to both abandoned city dreams cooling down, like a desolate castle. It signifies melancholic feelings due to unfulfilled hopes and personal losses, leaving hearts cold just as the surroundings do.
