Create a visual piece with an Eastern festive illustration style around the theme of Dragon Boat Festival. The composition features large areas of clean white space for breathability, with the main subject not centered but organized into a strong curved motion trajectory, like a circular boundary swept by a wide brush. The main elements follow the arc, with figures, objects, or thematic symbols arranged in a rhythmic progression, forming a reading path that enters from the edge, flows around, and leads the eye back to the blank center. The background uses layered transparent watercolor and gouache washes, with light semi-transparent broad brushstrokes, dry brush effects, ink splashes, and dotted pigments on the outer ring, and denser thematic patterns and fine color dots on the inner ring, retaining uneven hand-painted edges and paper texture. Colors are derived from the theme but must maintain a bright, light, clean, and high-value system: light background dominates, medium-saturation colors form the circular motion as structural hues, and a few high-saturation warm colors or thematic accents pop only at the edges of subjects, dots, and key nodes, creating clear color gradation and festive vitality. The main shapes maintain a flat illustration feel with simple outlines and refined local details, with figures having a slightly childlike and narrative proportion, moving uniformly along the arc. If text is added, place it in the white space as a quiet anchor point, with small typewriter-style explanatory text paired with a classic serif title of contrasting thickness, loose letter spacing, and restrained hierarchy, without overpowering the main motion. The overall texture should resemble a modern hand-painted poster on clean rice paper or fine-textured canvas, transparent, airy, and ceremonial, avoiding crowded layouts, photorealistic looks, dirty vintage filters, and muddy yellow tones. Theme: Dragon Boat Festival. Purpose: 2026 Dragon Boat Festival seasonal poster. Aspect ratio: 9:16.
