`煎饼` is more than just a food; it's a cultural icon representing the rhythm of daily life in China.
`煎饼` is a term you'll use in very specific, informal, and everyday contexts, primarily when buying street food.
The connotation is always positive and casual. It's a food of the people, enjoyed by everyone regardless of social status. You wouldn't find it on the menu at a fancy restaurant; its home is the humble street cart.
