In provincial Tibet, families still rely on traditional stoves for cooked food and warmth. These stoves sit upon an earthen platform, and they are curved with an opening at the front to load in firewood. On one side of these stoves, there is a hole, which is connected by a pipe to another hole in a wall near the stove. Smoke from the stove travels through this pipe to the exterior of the house. This riddle compares the path of stove smoke to a bit of mucus being blown out of a nostril and into the great outdoors.
