《金史·本纪·卷十四》
不久皇帝考虑孔元措是圣人的后代，山东贼寇多，恐怕他遇害，就没让他去。辽东贼寇蒲鲜万奴假称皇帝年号，改元天泰。
既而上念元措圣人之后，山东寇盗纵横，恐罹其害，是使之奉祀而反绝之也，故有是命。辽东贼蒲鲜万奴僣号，改元天泰。
The emperor soon reconsidered, arguing that Kong Yuancuo was a descendant of the Sage and that there were many bandits in Shandong, and he was afraid he would be murdered, so he did not send him there. The bandit Pubian Wanu in Liaodong began to claim the emperor’s reign title, changing the era name to Tiantai.
