You'Never Know

In the State of Zhao,there was once of a scholar by the name of Gongsun Long.He was a vain man and thought highly of himself.
"I don't keep company with people who have no talents,"he told his disciples.
One day a man dreesed in rags came up to him saying, "Please take me as your disciple."
After looking the man up and down,Gongsun Long replied coldly,"Tell me about your talents."
"Well,"said the man ,"I have a loud voice which can travel very far."
"Is there anyone among you who has a loud voice?"Gongsun Long asked his disciples.
"No,sir!"they replied
Gongsun Long took the man as his disple.His other disples were secretly laughing among themselvies."What is the use of a loud voice?"they sneered.
A few days later,Gongsun Long and his disciples had to make a trip to the State of Yan.Theycame upon a large river.However,not a boat was in sight except one lying on the distant shore.
Gongsun Long told his new disciple to prove his talent.The man gladly heeded the request and bellowed across the river.Very soon the boat was rowed over to ferry them all.
