A vertical promotional poster (9:16 aspect ratio, designed as a long scrollable mobile image) for a social media event titled "我的司机日记" (My Driver Diary). The image is composed as a cinematic vertical narrative from top to bottom: TOP SECTION: A vast golden sunrise sky transitioning from deep indigo at the very top through warm orange and pink gradients. The title text space is naturally integrated into the sky area. Wispy morning clouds catch the first light. MIDDLE SECTION: A modern heavy-duty cargo truck driving on a smooth asphalt highway, shot from a low 3/4 front angle. The truck's metallic body and chrome details reflect the golden sunrise light. Through the windshield, the driver's silhouette is faintly visible — a quiet moment of purpose. The highway stretches forward with gentle road markings leading the eye downward. BOTTOM SECTION: The road continues into the lower frame, flanked by rolling green hills and distant mountain silhouettes bathed in soft morning atmospheric haze. Warm volumetric light rays stream through the scene. The lower area has natural negative space suitable for text overlay. Overall technical style: photorealistic cinematic photography, golden hour warm amber and rose color palette, f/8 deep depth of field, 35mm wide-angle perspective, documentary-style authenticity. The mood is warm, hopeful, uplifting — celebrating the dignity of truck drivers recording their journey on the road. No text or watermark in the image.
