Minimal hand-drawn illustration, off-white paper background, dark gray sketch lines, muted umbrella yellow as the only accent color, lots of negative space, Notion-like doodle aesthetic, faceless round-headed human figure, clean editorial composition, conceptual rather than literal, simple background, no realism, no 3D, no painterly texture, no high saturation, no complex scene, no photographic detail. Add one short Chinese quote in a natural handwritten style near the bottom. The overall mood is restrained, lucid, slightly ironic, and emotionally calm. Keep the whole series visually consistent. Use Chinese wherever possible for any visible language or textual content, unless a proper noun, technical term, or special usage is better kept in its original form.
