This poem chooses trumpet and saxophone as metaphors. The sound of the trumpet is as lonely as light, shining in the thin clouds, while the saxophone falls like snowflakes. Trumpet is tallow in autumn. Leaves fell to the ground, the wind blew, and the trunk danced in the wind. The sound of trumpet and saxophone suddenly rose. Trumpet is like the triumphant return of a victorious army, while saxophone is the bugle in the March of a thousand troops. Then, the saxophone and trumpet sank, like the sound of drizzle, like the reference of sunset.
This is a way of playing and an episode of life. Explain that a person has highs and lows, which is the main theme of life.
