The turtle asked him: "Hey Frog , have you seen the sea? "
"The sea? Is it as big as my well ? You're welcome to come down here. "
The giant turtle was curious and he wanted to go down into the well but his right leg was caught in the railing around the well.
So the big turtle had to lie at the mouth of the well and tell how deep and wide is the sea. Only then did the frog know there was such a thing outside the well. The wide skies and Earth, which both surprised and the frog is ashamed by it.
After all, he is a frog at the bottom of a well that hasn't see the world yet.
一只青蛙住在一口废井里。它高兴时在井里跳来跳去，天热了在水中游上游下，觉得很快活。
“我是井里的主人，多么逍遥自在。”它正在自得其乐的时候，突然听到有人在叫它。
它抬起头向井口向上一看，只见一只大海龟的头几乎遮去了井口上的半边天。只听见大海龟问它：
“青蛙老弟，你见过大海吗？”
“大海？有我的井大吗？海龟老兄，欢迎你下井来做客。”
大海龟被它说动了心，真想下井去看看，可是它左腿还没跨进井去，右腿的膝盖就已被井栏绊住了。
于是大海龟只好伏在井口，告诉青蛙海有多大多深多广。
青蛙这才知道，井外还有这么大的天地，它又惊奇又惭愧，感到自己的见识太渺小。
成语井底之蛙比喻见识短浅却又妄自尊大。
