《宋史·列传·卷一百二十二》
又在二十三处险要之地设立兵营谨慎戍守，把全城分为十处地方，分别巡逻内外，白天自由行动，晚上守城，有敌情就参战。
又栅险要二十三所谨戍之，厘城止为十地分，分巡内外，昼则自便，夜则守城，有警则战。
He also guarded 23 important strategic locations with military camps, and divided the entire city into ten defensive locations, for both internal and external patrols. People moved freely during the day, and locked down the city at night, and would go into battle as soon as there was an enemy situation.
