## Prompt

```
Create a 45° isometric miniature 3D diorama showing a cross-section slice of a single ordinary day in [CITY NAME].

The base is made of layered natural earth and stone strata, cut open to reveal the underground infrastructure of [CITY NAME] as it authentically exists — whether subway lines, tram tunnels, utility pipes, or bare geological foundation.

Rising above: a street-level scene that genuinely reflects the urban character of [CITY NAME] — the architecture, density, building typology, street culture, and pace of life should all feel immediately recognizable as this specific city. Let the city's own identity determine whether this looks like a dense high-rise block, a low-rise neighborhood, a canal-side street, a market boulevard, or anything else.

Include a multi-story building with a visible cross-section interior — showing how people actually live inside: room layouts, furniture, daily activities, and the textures of domestic life as they exist in [CITY NAME].

Populate every layer with tiny faceless figures going about their day: underground transit users, street-level pedestrians, vendors, cyclists, residents visible through cut-open floors, and rooftop life above.

Lighting transitions naturally by layer: underground is cool and dim, street level holds soft ambient daylight, upper floors catch a gentle golden glow at the top. Materials and colors should reflect the local palette — stone, brick, concrete, glass, wood, tile — whatever is honest to [CITY NAME].

The entire composition reads as one unified vertical slice — from bedrock to skyline — capturing the essence of an ordinary day in [CITY NAME].

Solid warm off-white background. Bold title "A Day in [CITY NAME]" at top-center, subtitle "Every layer of city life, from stone to sky" beneath, minimal iconic skyline silhouette of [CITY NAME] below. All text contrast auto-matches background.
```

## 中文提示词

创建一个45°等距微缩3D立体模型，展示 [CITY NAME] 一个普通日子的横截面切片。

底座由分层的天然泥土和岩石层构成，切开以展示 [CITY NAME] 真实存在的地下基础设施——无论是地铁线路、有轨电车隧道、公用管道，还是裸露的地质基础。

向上延伸：真实反映 [CITY NAME] 城市特征的街景——建筑、密度、建筑类型、街头文化和生活节奏都应让人一眼认出是这个特定城市。让城市自身的身份决定它看起来是密集的高层街区、低层社区、运河边街道、市场大道，还是其他任何样子。

包括一座可见横截面内部的多层建筑——展示人们实际如何在内部生活：房间布局、家具、日常活动，以及 [CITY NAME] 存在的家居生活纹理。

在每一层都填满正在度过一天的微小无脸人物：地下交通用户、街道上的行人、小贩、骑自行车的人、透过切开的楼层可见的居民，以及上方的屋顶生活。

光线按层级自然过渡：地下阴凉昏暗，街道层保持柔和的环境日光，上层顶部捕捉到温柔的金色光辉。材质和颜色应反映当地色调——石头、砖块、混凝土、玻璃、木材、瓷砖——任何对 [CITY NAME] 来说真实的东西。

整个构图呈现为统一的垂直切片——从基岩到天际线——捕捉 [CITY NAME] 平凡一天的精髓。

纯暖米白背景。顶部中央是粗体标题“[CITY NAME] 的一天”，下方是副标题“城市生活的每一层，从岩石到天空”，下方是 [CITY NAME] 的极简标志性天际线剪影。所有文本对比度自动匹配背景。
