《资治通鉴·唐纪·唐纪二十》
张嗣明、徐敬真多诬告牵连海内相互认识了解的人，说他们图谋不轨，期望这样能免除死罪。于是朝野人士被牵连判死罪的人很多。
嗣明、敬真多引海内知识，云有异图，冀以免死；于是朝野之士为所连引坐死者甚众。
Zhang Siming and Xu Jingzhen falsely accused many people who knew and understood each other around the country, saying that they were plotting treason, hoping that this would enable them to avoid the death penalty. As a result, many people in the imperial court and around the country were falsely implicated and sentenced to death.
