Composed of folk figures, heritage artifacts, traditional costumes, opera face paint, paper-cut patterns, New Year print graphics, embroidery motifs, ceramic ornaments, auspicious clouds, ripples and seals, expressed as paper cut-and-paste, old-magazine collage, retro woodblock print and hand-printed color overlay. The key visual must not stand isolated in the center; it must overlap and interweave with the title, seals and patterns, forming a rich yet restrained layered relationship. The title uses large Chinese brush calligraphy, ink-black or dark brown, with flying-white strokes, accents and a handwritten texture; the subtitle and caption text mix small Song/sans-serif fonts, moderate density and clear hierarchy. Palette mainly off-white, old-paper yellow, light ochre, warm brown, sand-gold and ink-black, with a touch of 【accent color】.
