老北京胡同提示词，使用chatgpt image 2.0模型。

1985 Beijing hutong alley at dawn, a barefoot tofu seller
carrying two wooden buckets across his shoulder, steam
rising from a yutan stall, vintage Flying Pigeon bicycles
parked against grey brick walls, autumn leaves scattered
on wet cobblestone, an old man in Mao suit eating
jianbing from a street cart, neon shop signs flickering,
warm tungsten streetlight glow, Kodak Portra 400 film
grain, documentary street photography by Wang Fuchun
