凉心凉城
[liáng xīn liáng chéng]
The literal meaning is 'Cool Heart, Cool City,' symbolizing an individual who feels detached from the bustling and busy surroundings. It could mean the person finds him/herself in a state of loneliness in their living environment, where people do not understand them well and the city does not bring much excitement. 'City', here, refers more to a general living environment instead of an exact place on a map.
