《北史·列传·卷五十》
东魏将领侯景投奔南梁，魏收起草给南梁的文书，假称独孤信占据陇右，不听从宇文氏的号令，便说东魏 不用忧虑关西的西魏 ，可以全力对付梁国，是用来吓唬梁人的啊。
东魏将侯景之南奔梁也，魏收为檄梁文，矫称信据陇右，不从宇文氏，乃云 无关西之忧 ，欲以委梁人也。
When Hou Jing, a general of the Eastern Wei Dynasty, defected to the Southern Liang Dynasty, Wei Shou drafted an official document to the Southern Liang Dynasty, falsely claiming that Duguxin had occupied Longyou and refused to follow Yuwen's orders. He also said that the Eastern Wei Dynasty had no need to worry about the Western Wei Dynasty in Guanzhong and could concentrate on dealing with the Liang Dynasty, in order to frighten the people of Liang.
