Corely use "diagonal potential energy" composition, but do not directly draw obvious diagonal lines.

First determine a hidden diagonal visual axis, letting the visual weight of the key visual, Chinese title, patterns, date information, and white space progress step by step along the same direction.

The key visual bears the main weight; large Chinese titles must participate in the layout, and can be misaligned, vertically arranged, partially cropped, or slightly interspersed with the main subject; English titles, dates, and institution information are scaled down and concentrated in 2–3 areas, forming a clear font size hierarchy.

Each piece uses only one set of auxiliary pattern language and makes it relate to the theme itself, such as sound waves, map folds, artifact rubbings, or plant rubbings. Do not add multiple sets of decorative elements at the same time just for the sake of richness.

The background also needs to participate in the design: use art paper textures, extremely faint pattern afterimages, drawings, specimen information, or material textures, giving the white space layers while remaining clear from a distance.

Overall information volume is medium to high, but there must be a hierarchy:
First glance sees the composition and main subject;
Second glance sees the Chinese title and patterns;
Third glance reads the English, dates, and auxiliary information.

Color is controlled to 3–4 primary colors, creating tension through scale, cropping, overlapping, density, and white space.

Overall effect: cultural exhibition poster, editorial design, mature print publication feel, rich but not messy, diagonal potential energy exists naturally, do not deliberately arrange elements just to be "diagonal."
