Create an elegant 2026 Spring city-promotion poster for Guangzhou with a festive Lunar New Year atmosphere. Use a vertical 9:16 composition on a pure white textured paper background, with generous negative space and an S-shaped flowing composition. In the lower right, place a tiny figure in traditional Chinese clothing waving a long red silk dance ribbon. As the ribbon sweeps upward toward the upper left, transform it into a majestic mountain-and-river form through double exposure. Inside this flowing red silk river, overlay a hand-painted Guangzhou cityscape that includes mountains, sea, river, Guangzhou Tower, the Zhujiang New Town skyline, the Pearl River, historic Guangzhou architecture, a cruise ship, and Baiyun Mountain. Use a refined guochao visual style with mist, ethereal clouds, rich colors, complex structure, and abundant detail, while keeping the large white background fresh and elegant. Place "SPRING 2026" in the lower-left layout area, with vertical Chinese promotional copy meaning "Millennium Commercial Capital, Charming Guangzhou". Make the typography graceful, generous, clear, complete, and readable. Output aspect ratio: 9:16.
