These days the bean curd sold in a car has lost a lot of its former customers despite its unchanged high quality. As more and more cheap vegetables have come in, people don't rush to buy the bean curd any longer. In the past winter and spring, it was the customers who were waiting for the coming of the car selling toufu. Now it's the other way round. The red loudspeaker on the car was rarely used for the toufu sold well. Recently it has begun to help the seller advertise. The toufu was sold out quickly before; at present the seller has to drive along the street hawking his goods when he finds no customer coming to the place where he usually stays.
