Midnight snacks and night markets
For some cultures, eating late feels unhealthy or unusual. In many Chinese cities, late-night food can be part of friendship, work stress, travel, and urban memory.
After-hours intimacy
Night food lowers the formality of the day. People sit closer, speak more directly, and often use food to stretch time with friends.
This topic pairs well with citywalk and city bu city because night markets are easy to film and easy to feel.
