中国成语故事：角象龙鸣

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."

大夫权造了一只能发出龙的叫声的号角，来到南山旁的深水潭边吹奏。

池中的三角鳖听到这种声音，以为人们将要来把自己抓住煮了吃，惊恐之下，力竭声嘶地张开大叫。

大夫权却以为这是真龙的叫声。便找到公之奇，表示要学习真龙的叫声。公子奇告诉他：“你听到的不过是三足鳖的叫声，真龙的叫声人们很少能听到，你那号角本来就不是龙叫，如今又把鳖当成龙，就更假了，你不过是抛弃了一种假的，选择了另外一种假的而已。”
