Generate a poster with a strong sense of design using a diagonal composition.

First establish a clear diagonal visual axis, then organize the subject, typography, and white space around this axis, rather than stacking decorative elements first.

Let the subject itself form a diagonal momentum:
For group portraits, use character actions, sizes, and arrangements to create a continuous diagonal movement;
For spatial types, use architectural sections, perspective, and light and shadow to create a diagonal convergence;
For typography types, use large text advancing along the diagonal axis, enlarging, cropping, and overlapping;
For single-object types, use the object's own contour, center of gravity, and tilted posture to naturally form a diagonal tendency.

Keep only one main visual direction in the entire image; other elements only follow or balance it, without creating new visual competition.

The subject bears the main visual weight, leaving 25%–40% white space. The Chinese title serves as the visual focal point, while small English text and date information are concentrated in 1–2 information zones. Use 2–4 colors, and enhance tension through scale, cropping, overlapping, and asymmetrical layout.

The key is not to "draw a diagonal line," but to let the subject, text, and white space together form a diagonal reading path.

Editorial Graphic Design, mature, restrained, clear, and tense, like a real cultural exhibition poster.
