When we travel, we should pay attention to the signs on the road. They can help us find the right direction（方向）.
One day, Mr Smith drives his car to a farm. On the way he sees a sign with words "Turn right. Don't go straight". He looks ahead（朝前面）but sees nothing wrong. So he goes on. After a few minutes, he sees a broken（破损的）bridge and he can't cross it. So he turns back. On the way, he sees some words on the sign's back（后面）. It says "WELCOME BACK."
In China, everyone needs to know the rules of the road.
