Create a vertical 9:16 composite poster with four fictional smartphone content screenshots arranged as iPhone-sized cards in a clean 2x2 grid. Use Chinese UI text, but keep all platform names fictional and avoid real app logos. Card 1 shows a warm educational short-video screenshot about older parents not blindly pressuring adult children to marry, with an older adult speaker in a cozy room and headline “少管闲事 别盲目催婚”, plus supportive copy about marriage not being a task and happiness having its own rhythm. Card 2 shows a bright AI-learning short-video screenshot about keeping up with the AI wave, with a laptop, abstract AI interface, and headline “跟上AI浪潮”, plus copy such as “从基础开始 / 每天学一点”; avoid hard price promises or guaranteed teaching claims. Card 3 shows a lifestyle social-note screenshot about the hidden pressure behind refined appearances and consumer-debt risk, with a stylish young adult woman at a vanity desk, receipts, and headline “精致背后的压力”, plus copy about rational consumption and avoiding loan pressure. Card 4 shows a sober livestream preview screenshot about a fictional relationship-choice or divorce-discussion preview, with two empty studio chairs, neutral host avatar, headline “直播预告：关系选择”, and copy about rational communication and respecting decisions. Use realistic mobile screenshot mockups, status bars, generic like/comment/share icons, balanced colors, and public-safe modern Chinese social-media UI styling. Avoid real platform names or logos, Douyin/Xiaohongshu/Kuaishou/WeChat branding, Apple logos, QR codes, URLs, real person likenesses, legal/financial guarantees, predatory loan promotion, exploitative divorce framing, or misleading education price claims.
