Create a vertical 9:16 fictional primary-school Chinese language textbook page for grade three. Make it look like a clean printed textbook spread photographed or scanned straight-on, but do not copy any real publisher, real textbook brand, or existing lesson text. Use a soft white page background, a small top header indicating Chinese language class and grade level, a lesson number, and a large brush-style Chinese lesson title about a bird riding on a boat. Add several paragraphs of original, age-appropriate Chinese reading text with pinyin annotations above selected characters, margin notes, numbered vocabulary callouts, and a small reading-help sidebar. At the bottom, include a gentle watercolor-style illustration of a rainy riverside scene with a small covered boat, a boatman, misty Jiangnan-style water village scenery, willow trees, and a colorful kingfisher perched near the bow. Add a vocabulary accumulation strip with several Chinese words. The page should feel like a plausible educational textbook page, warm, readable, organized, and child-friendly, with Chinese typography that is as clean and coherent as possible.
