凉晨薄雾少年时薄晨微光少年时
[liáng chén bó wù shăo nián shí bó chén wēi guāng shăo nián shí]
It's like describing one's youthful period ('少年时'), repeating it for emphasis. With phrases '凉晨薄雾' (chilly morning light fog) and '薄晨微光' (light mist during dawn), this conveys the fleeting beauty and innocence felt at youth's start, surrounded by early mornings’ serene atmosphere.
