When you are in Hong Kong, you must be very careful in the streets because the traffic drives on the left. It is different from that in other areas of China. If you are the 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, people on foot mustn't cross.
When people go to or come from work in the morning and evening, the streets are very busy. It is the most dangerous time. Tragic(悲剧) are often possible to happen then, especially(尤其) 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. 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.
