Weekend Seoul travel guide poster

Generate a polished one-page Chinese travel guide poster for a fast weekend trip from Nanjing to Seoul in May. Use LARGE highly legible Chinese text, short phrases only, and no paragraph blocks. Focus on shopping, skincare, and a stylish Seongsu-dong route. Layout: big title, 4 modules only (行程 / 区域推荐 / 购物清单 / 美妆护肤), each with 2 to 4 short bullet points, plus a small cute route map with icons. Clean editorial infographic style, soft pastel colors, neat spacing, high readability, modern Xiaohongshu travel card aesthetic. Avoid tiny text, avoid dense explanations, avoid garbled characters.
