《史记·八书·律书》
如今既不能销毁兵器，长守安定，但愿暂且坚守边防，远设斥候，派遣使者，缔盟结好，使北部边陲得到休息安宁，功劳就算大得很了。
今未能销距，愿且坚边设侯，结和通使，休宁北陲，为功多矣。
Now that we cannot destroy weapons and maintain stability for a long time, I hope to temporarily defend the border, set up scouts in the distance, send envoys, form alliances, and make friends so that the northern border can rest and be peaceful. This would be a great achievement.
