Is it this song?
The main image here is "the moon". "Clear autumn sky", "laurel shadow helps sparse" and "lack of brightness" are all descriptions of the autumn night sky, in which a bright moon shines brightly and quietly. The author thinks that his official career has been ups and downs, and he has been traveling for half his life, but now he is accompanied by a group of teenagers ("teenagers chase after me") and entertained by the faint flute ("wind music" and "blowing frost bamboo" means smelling the flute), which shows Huang Tingjian's broad-minded and optimistic mood.
Vernacular translation
It's sunny after the rain, a rainbow appears on the horizon, and the autumn sky in Wan Li is clear. Such as the mountains with beautiful eyebrows, washed by rain, seem to be covered with new green clothes. The osmanthus trees are still thick in the middle of the month. How can we say that the moonlight is not bright tonight? Where is Chang 'e on a sunny day in Wan Li? She drove this full moon and galloped in the night sky. The moonlight is cold, who shines on this altar wine?
A group of young people accompanied me, treading a quiet path in the cool evening breeze, and walked into the Zhangjia Garden, which was full of trees, drinking and talking happily. Let's fill the gold lotus leaf cup in our hands. Although we are away from home in Wan Li, it's really rare to have a happy time to drink wine. I've been wandering all my life, traveling all over the country, and I like listening to the frost flute on the breeze best. After hearing this, Sun Lang smiled and blew a more melodious flute.
