One man said to him,"You are wrong.There is a place to the east of the Yellow Rivers called the North Sea.The North Sea is really big."He Bo said,"I don't believe it .Big as the North Sea is, can it be bigger than Yellow River?"The man said,"Should the water of several Yellow River flow into the North sea,it could not fill the North Sea,let alone one Yellow River. "

  He Bo said obstinately,"I don't believe it,for I have never been to the North Sea."

  Having no alternative,the man said,"You will not be able to" understand what I mean until you have a chance to see the North Sea for yourself."

  Winter came,and torrential rain had been falling for days on end.Rivers big and small emptied themselves into the Yellow River,making the Yellow River even broader.Standing on one side of the river,people could hardly tell what animals the oxen and horses on the other side of the river were.Thus He Bo was even more proud,thinking that all the magnificent sights were accumulated here.Then ,remembering the North Sea which had been mentioned to him before,he decided to go there and have a look.

  He went downstream,and arrived at the river mouth to the sea.Suddenly,the god of the North Sea,whose name was Biennia Ruo,appeared before his eyes.With a smile,Beihai Ruo was welcoming He Bo to the North sea.He looked ahead,and saw that the North Sea,with its vast expanse of water,was boundless.With a dull look in his eyes,He Bo stood there for a while.Finally he said to Beihai Ruo with deep feeling,"As the common saying goes,some people go so far as to think that they are more knowledgeable than anybody else when they have got some knowledge.Actually I am one of such people.If I had not seen with that the Yellow River is matchless in the world.If I remained like that, I would be laughed at for ever by sensible people."
