《魏书·列传·卷二十三》
如果宋国的重臣争权夺利，必然引发混乱，然后派遣将帅扬我军威，可以不烦劳士兵，就取得淮水以北的土地。 
如其强臣争权，变难必起，然后命将扬威，可不劳士卒，而收淮北之地。 
If the important ministers of the Song Dynasty fight for power and profit, it will inevitably lead to chaos. Then sending generals to show our military might can enable us to seize the land north of the Huai River without fighting.
