《宋书·列传·卷六十四》
如果广大的军队聚集在一起驻防，则必然破坏农事；驿车四处奔走混乱不堪，则打仗时行动必定迟缓；用散乱的金银进行赏赐，其耗费必然庞大；用客籍代替土籍驻守，日子久了，必然嗟怨四起。
若盛师连屯，废农必众，驰车奔驲，起役必迟，散金行赏，损费必大，换土客戍，怨旷必繁。
If the big army gathers for defense, the farming will definitely be damaged; if relay horse stations are everywhere, military actions will inevitably be slow; spending scattered gold and silver as rewards, the cost will be huge; if foreign soldiers are used to replace native ones, they will complain after a long time.
