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. Traffic is the most dangerous 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. So you must be careful. Have a look first,or you will go the wrong way.
