One night Wu Gang was lying in bed. Then suddenly a loud cry for help woke him up. He looked out of the window and found his neighbour's house was on fire.

　　Wu Gang hurried to telephone 119 for help. Then he ran out at once. He saw many people trying to put out the fire with water, and he quickly joined in. After some time, the firefighters arrived, the big fire was out at last. Luckily, no house was destroyed by the fire and all the people were safe.
