《资治通鉴·唐纪·唐纪二十三》
当初，左台大夫、同凤阁鸾台三品魏元忠曾担任洛州长史职务。在魏元忠到任以前，洛阳令张昌仪倚仗几个兄长的权势，每次到洛州长史衙门参拜，都不按规定在庭下站立，而径直走上长史办公的大厅；魏元忠到任后，叱令他下去。

Originally, Left Tai dafu and Tongfengge luantai sanpin Wei Yuanzhong had been magistrate of Luozhou. Before Wei Yuanzhong took office, the Luoyang magistrate, Zhang Changyi, relied on his brothers’ power to always go directly into the magistrate’s office when he visited, without standing in the courtyard as required; once Wei Yuanzhong arrived, he ordered him out.
