凉城小巷旧少年
[liáng chéng xiăo xiàng jiù shăo nián]
'Old Youth in Cool City Alley' evokes imagery of youth and nostalgia. '凉城' (liáng chéng) means 'cool city,' possibly alluding to a place known for its cooler climate, whereas '小巷旧少年' (xiǎo xiàng jiù shào nián) refers to old youth, perhaps a young person from simpler times, wandering through narrow alleys. The username reflects longing for the past and lost innocence.
