A man and his little son spent their summer vacation walking through the mountains far from their city. One day, the little boy slipped 20-30 meters down the side of the mountain. Finally he was able to grab onto a tree branch and hold on.
“Help me!” he cried out.
“Help me!” a voice shouted back.
The boy was very surprised. “Who are you?” he shouted.
“Who are you?” the voice shouted back.
“You are a fool!” he said.
“You are a fool!” the voice came back.
At that moment, his father got to him. “Someone is talking to me but I can’t see who he is,” the boy said to his father.
“Son, that is called an echo(回音),” his father said. “But really, it’s called life.”
“You are a winner!” the father cried.
