Once there was a famous masician in our country. His name was Gongsun YI. He liked to play the lute very much. One day he saw a cow eating grass. He was very happy and began to play the lute to the cow. The music

was very pleasant, but the cow still ate grass without listening to it.

Gongsun Yi went away unhappily. He wondered why the cow didnot listen to the nice music. In fact the cow could not understand music. Gongsun Yi just played the music to the wrong audience.(寓言故事对牛谈情)
