《晋书·列传·第九章》
单于因此与同族人谋划说： 和演计划杀王浚，眼看要成功而天竟下起雨来，使计划没有实现，这是天助王浚啊。
单于由是与其种人谋曰： 演图杀浚，事垂克而天卒雨，使不得果，是天助浚也。
The Chanyu thus conspired with his clansmen and said: He Yan planned to kill Wang Jun, and was about to succeed when the sky suddenly rained, causing the plan to fail; this was Heaven's help for Wang Jun.
