《金史·列传·卷三十七》
泰和六年，伐宋，尚书省奏： 军队发动，沿路官员，在职的区别登记，缺的选补上，年老不胜任职务选人替代后撤职，司、县各存留强干正职官一员。 
泰和六年，伐宋，尚书省奏： 军兴，随路官，差占者别注，阙者选补，老不任职者替罢，及司、县各存留强干正官一员。 
In the sixth year of the Taihe era, Song was invaded and the Ministry of Justice reported that when the army moved out, officials along the way, regardless of whether they were active or not, would be recorded and any vacancies would be filled in. Elderly people who were no longer able to perform their duties would be replaced by others after being selected and discharged. In the prefecture and county, only one strong and capable regular official would be retained.
