空城旧梦忆悲凉
[kōng chéng jiù mèng yì bēi liáng]
The net name conveys a feeling of loneliness and nostalgia. 'Kong Cheng Jiu Meng Yi Beiliang' means reminiscing over the past sad memories, which happened in an empty city (metaphorically a place void of happiness and life). It reflects sadness and perhaps a little yearning for what used to be.
