Warm ivory-white paper background with a slight natural paper grain and an old-print texture. The image uses a clear point-line-plane composition: one complete large circle as the core main visual, accompanied by 4–6 geometric elements of circles, rings, or partial cross-sections of varying sizes, forming an asymmetric vertical structure from top to bottom. Inside the circles, add fine textures related to the theme, such as water ripples, rock strata, glaze crackle, fragrance-diffusion patterns, plant textures, but keep everything two-dimensional and flat—no 3D, no photo collage, no e-commerce feel. Add a small amount of extremely thin vertical lines, arcs, or measurement lines as connecting and rhythmic elements. At the bottom or lower-center, place one small figurative subject as a visual anchor, for example a vessel, a flowering branch, a small installation, a specimen, or a human silhouette; the subject must not be too large and must not steal the dominance of the geometric composition. On the right, arrange the large vertical Chinese title【Title】in a slender, airy typeface with ample white space; on the left or lower-center area, place tiny fine text information, including the【Subtitle】,【Event info】,【Date and time】,【Location】, and a bit of English text, creating an editorial contrast of “large type extremely sparse, small type extremely dense.” Ample white space, restrained information density; the layout should look like an independent publication or exhibition poster, not a template image. Use a low-saturation color scheme, with the【Main color】as the core, optionally combined with 2–4 auxiliary colors, with hierarchy but not overly flashy. The overall temperament is quiet, artistic, with a Japanese editorial feel and a sense of being a finished work. No numbering, no watermark, no logo, no copyright text, no sparkle, no four-pointed star flares. Special requirements: the top main circle must be shown in full and must not be cropped on the left or top; the background must fully fill the entire canvas, with no extra white border or separate white column appearing on the right; the image should look like a complete work, not a placeholder template.
