The core is not simply placing text in the four corners, but using large Typography, color blocks, information zones, or patterns along the edges to exert visual pressure inward, naturally "clamping" the central subject into focus. The central subject remains complete, stable, and with clear visual weight. Do not intentionally tilt or distort it to fit the composition. The subject should carry approximately 40%–60% of the visual weight. Organize the layout according to the【压角方式】: Four-corner text pressure: All four corners have visual elements, but there must be clear hierarchy - 1–2 corners carry the main weight, the rest only serve as support. Do not make all four corners equal in size. Diagonal dual pressure: Choose two opposite corners as the main pressure points, letting large titles or color blocks clamp the subject from two directions. The other two corners only hold small information. Three-corner encirclement + one-corner release: Three corners form a visual enclosure, while the fourth corner is deliberately kept lighter to give the composition breathing room. Single-corner heavy pressure + diagonal response: One corner uses oversized text or a strong color block to carry the main pressure, the opposite corner responds with a smaller element, and the central subject remains stable. Large Chinese titles must genuinely participate in the composition. They may be partially cropped at the edges, flush against borders, or slightly overlapping the subject, but must remain clearly legible. English titles, dates, institutions, theme descriptions, and other small text should be concentrated in 2–3 zones, creating a clear typographic hierarchy through oversized Chinese characters, medium-sized titles, and tiny information. The background cannot be completely empty. It may include extremely faint patterns, archival information, structural diagrams, material textures, or explanatory traces related to the theme, giving the negative space "content" without competing with the subject. The entire poster uses only one set of primary auxiliary motifs, and they must have a genuine relationship with the theme. Color is limited to 3–5 main colors, and the poster must have a clear color stance. Overall information density is medium-high, but the visual hierarchy is clear: First glance: the subject and corner-pressure relationship; Second glance: the large Chinese title; Third glance: English text, dates, and auxiliary information. Each poster must have a complete theme and authentic content expression. Do not use large amounts of meaningless placeholder words. Even without the small text, it should stand as a valid visual work. Overall effect: cultural exhibition poster, magazine editorial design, mature printed publication feel - pressure at the edges, focus at the center, rich but not chaotic.
