《金史·列传·卷三十》
章宗虽然被封为原王，任丞相，徒单克宁还因为他没有被立为皇太孙，屡次向世宗皇帝请求。金世宗叹说 ：徒单克宁是社稷的大臣。 
章宗虽封原王，为丞相，克宁犹以未正太孙之位，屡请于世宗，世宗叹曰： 克宁，社稷之臣也。 
Although Zhangzong was named the original prince and appointed prime minister, Tudan Kein repeatedly made requests to Emperor Shizong because he had not been named the crown prince. Emperor Shizong of the Jin Dynasty sighed and said: Tudan Kenin is the minister of the country.
