Create a hyper-detailed square 3D illustration of the city [Beijing] wrapped around all sides of a floating cube suspended in the sky. The entire cube is covered with the city environment: modern skyscrapers, iconic landmarks, streets, bridges, parks, water features, highways, and urban lights that represent [Beijing]. The architecture flows naturally across every face of the cube — top, sides, and edges — forming a continuous miniature city that bends around the cube geometry. Buildings rise vertically from the cube surfaces, while roads curve across edges connecting different faces, creating a visually stunning cube-world city. Below the floating cube, place the city name "Beijing" as a separate clean 3D white text sculpture, centered under the cube, bold and elegant, casting a soft shadow. Environment: floating in open sky with soft clouds and atmospheric haze. Lighting: cinematic golden hour lighting, dramatic shadows, global illumination, volumetric light rays. Style: ultra-realistic architectural visualization, highly detailed textures, vibrant yet balanced colors, depth of field, cinematic composition. Render quality: ultra-sharp, 8K, photorealistic 3D render. Composition: square format, cube centered, city covering all cube faces, white 3D city name floating below the cube. No extra text except the city name.
