《宋史·列传·卷一百九十九》
希望陛下令四千户以上的县选朝官担任知县，三千户以上的县选京官担任知县。
欲望县四千户已上选朝官知，三千户已上选京官知。
I hope that Your Majesty will have counties with more than four thousand households select court officials to serve as county magistrates and have counties with more than three thousand households select capital officials to serve as county magistrates.
