    The traffic rule in England is different from that in China. When you are in England, you must be very careful on the street because the traffic drives on the left. You must look at the right first and then the left. If the traffic lights are red, the traffic must stop. Then the people can cross the road on foot. If the traffic lights are green, the traffic can go. People mustn't cross on foot.
