Poetry: The Meaning of rather critical

most of the songs of sad autumn lament that the youth is fleeting and the years are hard. The author relies on the autumn leaves and the sound of the flute, pinning the passing of time, but he is wandering in the maze of life. Melodious and poignant, tactfully and confusedly, green face is a metaphor for one's youth and beauty, and drifting, far away and seeing through reflects one's ignorance.
