《资治通鉴·唐纪·唐纪二十七》
哥哥鲁僖公作过弟弟鲁闵公的臣子，尚且不应把地位升到闵公之上，何况弟弟睿宗曾作过哥哥中宗的臣子，又怎么可以位居中宗之上呢？
兄臣于弟，犹不可跻，况弟臣于兄，可跻之于兄上乎！
Duke Xi of Lu was the elder brother and a subject of Duke Min of Lu. He should not have been placed in a higher position than Duke Min. Moreover, Emperor Ruizong was the younger brother and a subject of Emperor Zhongzong. How could he be placed in a higher position than Emperor Zhongzong?
