《三国志·魏书·二公孙陶四张传》
刚好遇上董卓被杀，皇帝就下令派使者段训前来封赏刘虞，增加他的食邑，让他总管六州；并提升公孙瓒为前将军，封为易侯。
会卓死，天子遣使者段训增虞邑，督六州；瓒迁前将军，封易侯。
Coincidentally, Dong Zhuo had just been assassinated. The Emperor sent an envoy by the name of Duan Xun to reward Liu Yu, increasing his fief and putting him in charge of six provinces. He also promoted Gongsun Zan to the position of General of the Vanguard, granting him the title of Marquis of Yi.
