《旧唐书·列传·卷六十四》
当初，仲升被包围几个月，吕在江陵患病，瑱在襄州，由于担心仲升对自己构罪，瑱于是顾望而不救援。
初，仲昇被围累月，吕諲病于江陵，瑱在襄州，又恐仲昇构己，遂顾望不救。
Originally, Zhongsheng had been surrounded for several months, and Lu was suffering from an illness in Jiangling. Tian was in Xiang prefecture and worried that Zhongsheng would frame him, so Tian just watched and did not send any troops to rescue him.
