《水经注·卷二十五》
也有人说是用绳索系住鼎往上拉，但没有拉上来，绳索就被龙齿咬断了。所以谚语说，高兴得太早，拉鼎断了绳。 
亦云系而行之未出，龙齿啮断其系，故语曰：称乐大早绝鼎系。
Some people also said that they used ropes to tie the cauldrons and pull them up, but they did not pull them up, and the ropes were bitten off by the dragon's teeth. Therefore, the proverb says, if you are too happy, you will break the rope when you pull the cauldron.
