往事深处少年蓝空城薄凉少年梦
[wăng shì shēn chŭ shăo nián lán kōng chéng bó liáng shăo nián mèng]
A rather literary netname which translates to 'In the depths of past events, there was a youthful blue sky; in an empty city filled with cool air lies the dream of a teenage boy.' This suggests a nostalgic reflection on the past, possibly about fleeting youth and dreams.
