At night in what appears to be a city in Vietnam, a sanitation worker dressed in dark clothing and a yellow safety vest stands inside a green, four-wheeled trash cart. The cart is in the street, just over the white line of a crosswalk. A person stands nearby, holding a clear plastic bag of trash. Behind the cart is a white car waiting for the cart to move, and behind that, parked motorcycles line the sidewalk in front of buildings with lit storefronts. Street lights illuminate the scene. The air is clear and still. A sign in Vietnamese hangs from a light pole, displaying the name "LONG CHAU" and promising no price increases on medicine.
