Create a vertical 9:16 2026 Chinese city-series promotional poster themed around [City]. Use a modern, colorful, bright, translucent guochao-inspired graphic style. Start with a large white textured negative-space background. Build the main composition around a red silk ribbon that spirals from the lower right toward the upper left, forming an elegant S-shaped visual path. In the lower right, place an East Asian woman waving the red silk, with clothing customized to the local culture of [City]. Let the ribbon extend into a long city scroll that blends the most recognizable landmarks, natural scenery, cultural icons, folk performance elements, architecture, neighborhoods, and local atmosphere associated with [City]. On the left side, design refined typography including "SPRING 2026", a vertical English city name, and a small seal-style Chinese city mark. Keep the series identity unified but not repetitive, with rich details, strong city recognizability, clear elegant text, premium graphic design, and a high-end travel poster feeling. Avoid real tourism logos, official seals unless authorized, inaccurate landmarks, cluttered collage, unreadable text, distorted architecture, stereotyped cultural details, extra watermarks, and low-resolution artifacts.
