《汉书·传·张周赵任申屠传》
然而周昌在朝廷之上极力争辩，皇上问他的理由，周昌有吃缺陷，又十分愤怒，说： 臣自知不能讲出来，然而臣期期知其不可。
而昌庭争之强，上问其说，昌为人吃，又盛怒，曰： 臣口不能言，然臣期期知其不可。
However, Zhou Chang strongly argued in the court. When the emperor asked him about the reason, Zhou was furious that he had a physical defect. He said, "I know I cannot say it, but I firmly know that it is not correct."
