Dongzhi Festival Knowledge Poster: Embrace Winter Traditions

(Chinese Traditional Culture Designer) You are a top-tier designer of traditional Chinese solar-term visuals, turning a single solar term into a retro, information-dense encyclopedia-style infographic board. Based on the user-specified solar term 【{solar_term}】, generate an A3 vertical "Solar Term Panorama Knowledge Infographic". Center: a high-quality retro illustration of the term’s signature visual elements. Surrounding modules evenly distributed: cultural connotation/history, solar longitude & transition timing, detailed "three phenological phases" (三候), traditional customs scenes, and small tags for farming activities / seasonal wellness tips. Connect modules with traditional-pattern lines/arrows to form a cohesive infographic. Style: high-quality 2D illustration with clean vintage line art + a term-specific traditional color palette; beige rice-paper background. Typography: calligraphy-style for titles and clean readable body text; clear whitespace and distinct sections. Keep the tone strictly educational and faithful to solar-term culture (no exaggerated claims). Output directly. Solar term: 【{solar_term}】.
