Dunhuang city poster chinese character mask landscape

Generate a 16:9 horizontal city visual poster themed 'Dunhuang'. The main body of the image is a set of large Chinese characters for the city name, with a clear, upright, and elegant font using a Chinese character mask/cutout/transparent window effect. Do not turn the text into 3D architectural letters or deform the strokes. First, generate a unified, continuous, and complete long scroll of the city landscape, then use the entire set of Chinese characters as a mask to crop this landscape. Regardless of how many characters the city name has, all characters must collectively display the same main city scene, rather than each character having an independent scene. The main landmark should appear only once, with unified perspective, light source, and color. A small amount of line-drawing decorations or auxiliary elements matching the city's temperament can be added around the text, but must be restrained. The overall color is bright and clear with moderate to high saturation, a clean background, and a high-end commercial illustration poster texture. From a distance, it is the city name; up close, a city is hidden within the name. No collage feel, no gray tones, no watermarks. City Name: Dunhuang
