Da Fuquan made a born that could make sounds of dragon. He blew the born by the deep pool near Mountain Nanshang.

Hearing the sound, the three-legged turtle in the pool thought that people were to catch it and eat it. So it got so frightened that it shouted hysterically with its mouth wide open.

Da Fuquan thought this was sound of a real dragon. Then he went to find Gong Zhiqi and told him he wanted to learn the real sound of a dragon. Gong Zhiqi told him, "What you heard was not real sound of a dragon but sound of a three-legged turtle. The real sound of a dragon is rare to be heard by people. The sound made by your born is not that of a dragon, and now it is even worse for you to mistake the sound of a turtle to be that of a dragon! You just give up one false thing to take up another."

大夫權(quán)造了一只能發(fā)出龍的叫聲的號角，來到南山旁的深水潭邊吹奏。

池中的三角鱉聽到這種聲音，以為人們將要來把自己抓住煮了吃，驚恐之下，力竭聲嘶地張開大叫。

大夫權(quán)卻以為這是真龍的叫聲。便找到公之奇，表示要學(xué)習(xí)真龍的叫聲。公子奇告訴他：“你聽到的不過是三足鱉的叫聲，真龍的叫聲人們很少能聽到，你那號角本來就不是龍叫，如今又把鱉當(dāng)成龍，就更假了，你不過是拋棄了一種假的，選擇了另外一種假的而已。”
