Many of the food vendors are on tricycles like this. This man has a 44 gallon drum with a fire within it and he is cooking sweet potatoes right in the city of Shaoxing. Imagine riding around with this huge fire just behind you. They are a delicacy and the workers as they finish for the day, will purchase one of these hot tasty cooked vegetable to eat at home or on the way home.One day I must try it. Supposed to be very tasty.
