时光深巷少女古道荒城少年
[shí guāng shēn xiàng shăo nǚ gŭ dào huāng chéng shăo nián]
The Young Girl in the Time Alley and the Youth on the Ancient Path in an Old City: This evokes imagery of young people wandering in the deep memory lane of history and time. It's full of nostalgia and reflection on the fleeting youth.
