Create a premium vertical 9:16 Chinese e-commerce product marketing board for an instant mixed grain powder drink. Use a fictional brand name, not any real food brand. The product is walnut, sesame, and black bean powder in a matte black retail box with metallic gold Chinese typography, a large swirling bowl or cup graphic on the front, and individual black sachets inside. Show the net weight as 320g, 32g x 10 sachets.
Use a premium dark food-ad layout with black, deep brown, warm gold, beige, and walnut-brown colors. Lighting should feel dramatic and glossy with warm rim light. The mood is luxurious, nourishing, healthy, and appetizing, but avoid medical or guaranteed health claims.
Build one tall composite board divided into major e-commerce sections plus a bottom video storyboard table. Top-left section: main product hero image with the retail box, drink cup, walnut, black sesame, black beans, grain powder, icons, and Chinese selling points such as mixed grains, rich aroma, individual sachets, and instant drink. Top-right section: details page with circular ingredient frames for black sesame, black beans, black rice, walnuts, and grain powder. Mid-right section: texture and taste feature panel showing a close-up gray-brown drink surface and Chinese copy about fine powder, rich smooth taste, and convenient nutrition. Mid-left lower section: how-to-make guide with three numbered steps, pour one 32g sachet, add 200ml hot water or milk, stir evenly and enjoy. Lower-left section: lifestyle scenarios for breakfast, office afternoon drink, fitness meal replacement, and bedtime warm drink. Lower-right section: portable sachet section with an open box showing sachets, freshness, moisture protection, and one-sachet-one-cup portion control. Bottom full-width section: a generic video promotion storyboard table with seven shots, not tied to any named video tool: product opening, ingredient close-ups, powder poured into cup, hot water stirring, drinking scenario, product benefit display, and ending slogan.
Scene elements include bowls of black sesame, black beans, black rice, walnut halves, and light beige grain powder; a thick gray-brown sesame-walnut-bean drink with a smooth surface swirl in a transparent handled glass cup; a spoon stirring or resting inside; walnuts on the table, scattered beans, grain stalks, dark tabletop, ingredient bowls, and an open package showing five visible sachets.
Use bold elegant Chinese metallic-gold display type for headlines, clean Chinese sans-serif body text with occasional English subtitles, thin gold divider lines, circular ingredient frames, front-facing hero box, angled sachet display box, close-up beverage macro, high-detail commercial food styling, shallow depth of field, crisp texture emphasis, and a polished 4K e-commerce key visual plus details page plus storyboard mockup.
