The composition centers on the interplay between the rigid vertical lines of architecture and the fluid, dynamic movement of a butterfly swarm. Fan utilizes a limited color palette to ground the scene in a quiet nighttime atmosphere, allowing the detailed textures of the sailing boats to stand out against the simplified forms of the city. The interaction of colors creates a sense of depth, drawing the viewer into a rich medley where the industrial and the ethereal coexist in silence.

By placing traditional vessels within a metropolitan setting, the work explores maritime heritage through a lens of surrealism. The butterflies represent a fluidity of identity, suggesting that even the most solid structures—boats, buildings, or history itself—are subject to the shifting currents of imagination. It is a thoughtful study in color theory and psychology, using the stillness of the night to highlight a moment of profound, rhythmic migration.
