《宋史·列传·卷一百四十五》

蜀北边旧有义士三万，本民兵也，监司、郡守杂役之，都统司又俾与大军更戍，成大力言其不可，诏遵旧法。
In the past, there were 30,000 righteous people on the northern border of Sichuan, who were local militiamen. The supervisory officials and county magistrates used them on their own accord. The commander-in-chief also required them to take turns guarding the border with the army. Fan Chengda argued that this was not feasible and the emperor issued an imperial edict, ordering everyone to follow the old law.
