《资治通鉴·魏纪·魏纪八》
当时，太常夏侯玄在天下极有威望，但因为与曹爽是亲戚，不能担任有权势的职位，平时常常怏怏不乐；张缉因为是皇后之父而免去郡守闲居在家，他也很不得意；李丰与夏侯玄和张缉关系十分亲密。
是时，太常夏侯玄有天下重名，以曹爽亲故，不得在势任，居常怏怏；张缉以后父去郡家居，亦不得意。丰皆与之亲善。
At that time, Taichang Xiahou Xuan was highly respected in the world, but because he was a relative of Cao Shuang, he was not able to hold a position of power. He was often unhappy; Zhang Ji was relieved of the post of county magistrate and lived at home because he was the father of the empress. He was also very unhappy; Li Feng had a very close relationship with Xiahou Xuan and Zhang Ji.
