兮以城空兮城以空
[xī yĭ chéng kōng xī chéng yĭ kōng]
'Xi (an ancient Chinese word often used in classical literature) to leave the city desolate, Xi to leave the city empty.' It seems to convey a sense of loneliness and abandonment, possibly after a big change like a relationship breaking down or leaving a place filled with memories behind.
