The theme of this piece of music is vivid and beautiful. It is based on the typical Western tango dance rhythm, with the soothing and smooth pentatonic melody rich in national colors as the keynote, and the free progression of the fourth degree downward. The alternating playing of flute and erhu, the light rhythm of plucked instruments, the plucked strings of bass instruments and the spacious tone of cymbals vividly paint a moving picture of a bright moonlit night for us, bringing people into a world of "bright moon moving, colorful clouds" A beautiful scene like poetry and painting.
