When you are in Hong Kong, you must be very careful in the street because the traffic drives on the left. It is different from that in other areas of China except Macao. If it's your first time to come to Hong Kong, you must look to the right side and then the left before you cross the street. If the traffic lights are red, the traffic must stop. Then people on foot can cross the road carefully. But if the traffic lights are green, the traffic can go, and people on foot mustn't cross.
When people go to or come from work in the morning and evening, the streets are very busy. Traffic is the most dangerous then, especially for the children.
When you go by bus in Hong Kong, you have to be careful too. You must always remember the traffic moves on the left. So you must be careful. Have a look first, or you will go the wrong way.
In Hong Kong，there are many big buses with two floors, and you can sit on the second floor. From there you can see the view of the whole city well. It's very interesting.
