Social Media Post - Gaokao Cheer Poster Wallpaper

Generate a flat illustration with a celebratory ritualistic feel centered on the theme "Good luck on the Gaokao". Keep a large area of white space at the top for breathing room, with a small signature, dash, and seal in the upper left corner to create a subtle introduction. Use a small amount of handwritten blessings or a theme slogan in the middle as an emotional transition. At the bottom, establish a main information area that looks like a combination of a printed seal and a ticket border, with uneven border thickness and hand-pressed ragged edges. In the main info area, prominently feature an oversized, gritty theme character or symbol with brushstroke textures spread across as a background, partially obscured by the central theme object. The central object should be shaped with clear line drawings and flat color blocks, standing upright and stable with small derived details, acting as the blessed focal point. Arrange small icons, inscriptions, round seals, and dense curved symbols around it so that information unfolds like layers of stamps on a handmade gift note, maintaining a rhythmic density. Colors are extracted from the material and cultural signals of the theme: large areas of high-brightness, clear, clean base colors for paper and air, while structural lines and main characters use clear accent colors derived from the theme, concentrated but not muddy. The central subject uses complete shading levels and a few supporting colors to distinguish information layers, with detail marks using low-area dot colors. The overall mood is bright, clean, solemn yet approachable, with a texture of fine paper fibers and slight registration errors, avoiding heavy aging, dirt, or smoke effects.
