Once upon a time in Guchao County, a river suddenly flooded and swelled. When the water receded a few days later, people discovered a huge fish stranded in a small harbor outside the small county. It weighed roughly 5000 kg. As the water was too shallow, the fish died on the third day. All the residents of the county ate the flesh of the big fish except for an old lady who felt sorry for the fish.

Suddenly, an old man appeared in front of the old lady and told her, “This fish is my son, who met a tragic end. Since you were the only person who did not eat my son, I will reward you handsomely. Let me tell you a secret: There is a stone turtle outside the city’s eastern gate. When its eyes turn red, your city will soon be flooded and submerged.”After hearing the old man’s words, the old lady would go out of the city’s eastern gate every day to check if the stone turtle’s eyes turned red. A child felt curious, and asked the old lady, “Why do you come to look at the stone turtle every day?” So, the old lady told the child what the old man told her.

The child wanted to play a prank on the old lady. One day, he painted the stone turtle’s eyes red. When the old lady saw that the turtle’s eyes had turned red, she quickly went out of the city. Suddenly, there appeared a little child dressed in blue robes who told the old lady, “I am the Dragon King’s son.”He led the old lady to the top of a mountain. When she turned and looked back upon the city, she saw that it had been submerged, and nothing remained but a lake.

　　有一天在古巢郡（也就是今日的巢湖，在今安徽省合肥市）這個地方，突然江水泛濫暴漲，隔了幾天水才退去，這時卻傳來在小郡外的小港灣出現一條很大的魚，重量大約有萬斤那麼重，由於水太淺了，到了第三天，這條大魚就死掉了，整個郡的人都吃到魚肉，唯獨一位老婆婆不肯吃。
　　這時出現一位老公公，他對老婆婆說：「這條魚是我的兒子，不幸碰到這種災難，只有你沒有吃我的兒子，我要重重的報答你，我先告訴你，如果東門外的石龜它的眼珠變成紅色的，表示這座城將會沉下去。」老婆婆聽完這番話後，每天都會到東門外去看石龜的眼珠有沒有變成紅色，有個小朋友覺得很好奇，便問婆婆：「婆婆您為什麼每天都來看石龜？」，老婆婆便告訴這個小朋友整件事情。
　　小朋友心想捉弄一下老婆婆，有一天便將石龜的眼珠塗成紅色的，老婆婆一看眼珠變成紅色，趕緊出了城，就在這時候，出現一位穿著青色衣服的小孩子，對她說：「我是龍王的兒子。」接著便帶著老婆婆到一座山上，老婆婆回頭一看，整座城都沉下去變成湖了。
