凉城凉梦凉人心
[liáng chéng liáng mèng liáng rén xīn]
The phrase '凉城凉梦凉人心' refers to a city filled with coldness where not only dreams feel icy but also it makes hearts numb. It expresses the sense of disappointment and sadness towards love or certain experiences which once seemed sweet, but in the end left only coolness in one's heart, reflecting a very desolate emotional state.
