《北史·本记·卷九》
当元毗还朝时，宇文泰上表给魏帝，说明高欢正拥兵河东，侯莫陈悦又据守水洛，部队首尾受敌夹制，请求暂缓回军京城。
及毗还，帝表于魏帝，辞以高欢至河东，侯莫陈悦在水洛，首尾受敌，乞少停缓。
As Yuan Bi returned to court, Yu Wen Tai memorialized to the Wei Emperor, explaining that Gao Huan was occupying He Dong with his soldiers, while Hou Mo Chen Yue was occupying Shui Luo. The army was being attacked and controlled on both sides, and requested that the army's return be temporarily delayed.
