A square-format social-media mobile feed screenshot collage displaying two Chinese educational study cards side by side on a clean white background with slight compression artifacts and subtle card drop shadows. Layout: Two vertical columns. Upper portion features two illustrated educational infographic cards; lower portion features post captions, creator profiles, and engagement stats. Thick, hand-drawn red marker circles highlight both like counters at the bottom. Left Card (Math): Beige lined notebook paper texture with neat blue and black handwritten Chinese text. Header: "[长方形和正方形·三年级]". Subtitle: "认识多边形·周长计算" with a 3-orange-star difficulty rating at the top right. Contains two main geometry diagrams: one labeled "长方形" showing a rectangle with dimension arrows, and one labeled "正方形" showing a square with equal side marks. Four small colored accent blocks nearby (blue, green, orange, yellow), plus a tiny cartoon figure walking around a perimeter. A semi-transparent dark rectangular overlay in the center reads "刚刚看过" in white text. Boxed formulas below: "长方形周长=(长+宽)×2" and "正方形周长=边长×4". Orange rounded pill badge at bottom: "理化笔记·原创内容". Right Card (Physics): Beige lined notebook paper texture with black handwritten Chinese text. Header: "[第六章 质量与密度]". Top row features three scientific illustrations: a balance scale ("托盘天平") with weights ("砝码") and sample ("待测物"), a horseshoe magnet with direction arrow, and a graduated cylinder ("量筒") filled with blue liquid. Four numbered sections below detail mass units, balance scale operation steps, density formula "ρ=m/V" with unit conversion "1 g/cm³ = 1000 kg/m³", and density measurement. Bottom orange callout box: "核心难点：单位换算 & 实验误差分析" and footer "理化笔记·原创内容". Bottom Feed Area: - Left caption in bold Chinese: "别只背公式！一张图讲透【周长】底层逻辑" - Right caption in bold Chinese: "天平使用8步法 + 密度计算模板，物理多拿12分" - Creator under each: small circular avatar with a yellow lightbulb icon and username "图解考点左老师" - Engagement: gray outline heart icons with like counts "[3184]" on left and "[1859]" on right, each circled with a thick red freehand marker loop. Style: Educational infographic, neat student notebook aesthetic, pastel vector accents, sharp Chinese typography, realistic social app feed screenshot crop.
