Lin Li, a teacher from Yantai, gives young students some advice on how to deal with danger
If you are in a traffic accident
If a car hits you, you should remember the car number. If you get badly hurt, you should call l20. If it is a bicycle, try to call your parents before you let the rider go. This is because you don't know how seriously you are hurt.
 If it is raining hard and there is lightning  
Don't stay in high places or turn on the TV. Don't use the phones. Keep away from trees.
When there is a fire
Get away as fast as you can. Put wet things on your body and try to find an exit. Don't take the lift.
 If someone is drowning  
If you can't swim, don't get into water. Cry out for help.
If you are robbed  
Keep calm. If you can not cry for help or run away, give the robber your money. Try remember what the robber looks like and tell the police.
Remember that danger is never as far away as you think. Protect yourself at all times !
