《吕氏春秋·纪·仲春纪》
尧把天下让给子州支父，子州支父回答说； 让我做天子还是可以的，虽是这样，我现在正害着忧劳深重的病，正要治疗，没有余暇顾及天下。 
尧以天下让於子州支父，子州支父对曰： 以我为天子犹可也。虽然，我适有幽忧之病，方将治之，未暇在天下也。 
Yao offered the world to Zizhou Zhif, and Zizhou Zhif replied: “I can be emperor, but I have a very serious illness right now. I’m taking medication and I don’t have the time to take care of the world.”
