Once, two hunters went hunting in the forest. One of them suddenly fell down. His eyes rolled back, and he seemed to have stopped breathing.
The other hunter immediately took out his mobile phone and called the emergency center.
The operator said calmly, "First, you should make sure that he is already dead."
Then, the operator heard a gunshot from the other end of the line. Next, he heard the hunter ask, "What should I do next?"
