《淮南子·汜论训》
过去苌弘是周王室执掌历数的官员，天地之气、日月运行、风雨变化、律历度数，苌弘他无所不知，然而他却就是不能预见掌握自己的命运，所以最终还是死于非命，被人斩于刀下。
昔者苌弘，周室之执数者也。天地之气，日月之行，风雨之变，律历之数，无所不通，然而不能自知，车裂而死。
In ancient times, Chang Hong was an official in charge of calculating time in the household of the emperor of Zhou, and he had a thorough knowledge of the changes in nature, the movements of the heavenly bodies and the course of time. But he was unable to foresee his own end, and so he was murdered in the end, being hacked to death with a sword.
