According to legend, during the Spring and Autumn Period, Gou Jian, the King of Yue, had two talented heroes, one was Fan Li and the other was Wen Zi. They were both loyal to the King of Yue. Gou Jian, the king of Yue, sent troops to attack Wu, and the result was a fiasco. With the help of Fan Li and Wen Zi, Gou Jian, the King of Yue, saved his strength and wiped out the State of Wu in one fell swoop.
Fan Li knew that Gou Jian, the King of Yue, was cruel. After serving the monarch and defeating Wu, he went to the countryside and left the capital, abandoning his wealth and living in seclusion. Fan Li missed his friend Wen Zi's safety and sent him a message, saying, "Birds are exhausted, so it's good to hide with a bow;" A sly rabbit dies, but a running dog cooks. Why not run away from the disaster? "Wen Zi didn't listen to Fan Li's advice at first, but later he learned that Gou Jian, the King of Yue, really killed heroes, so he pretended to be ill and didn't go to court, but it was too late, and he was finally sentenced to death.
The phrase "when a rabbit dies, a dog cooks" means "when a bird is tired, it is good to hide with a bow; A wily rabbit dies and a running dog cooks ",which can be used for rulers to kill heroic generals and ordinary friends to kick down the ladder." "
