《资治通鉴·晋纪·晋纪二十九》
但是雷恶地智谋韬略非常人可比，如果他向南结交魏揭飞，向东结交董成，而且占领杏城、李润，并据守不去，那么，长安东北的一带就不是我们的了。 
恶地智略非常，若南引揭飞，东结董成，得杏城、李润而据之，长安东北非吾有也。 
But Lei Edi is extremely intelligent and resourceful, so if he allies with Wei Jiefei in the south and Dong Cheng in the east, captures Xingcheng and Lirun, and refuses to surrender, then the northeast of Chang'an will no longer be ours.
