《管子·匡君大匡》
鲁国约请会盟说： 鲁是小国，当然不带兵器，若带兵器开会，就是以战争状态传闻于各国诸侯，您还不如作罢。
鲁人请盟曰： 鲁小国也，固不带剑，今而带剑，是交兵闻于诸侯，君不如已。
The state of Lu asked to host a meeting, saying: Lu is a small state, and of course we will not bring weapons. If we bring weapons to the meeting, it will be tantamount to spreading rumors of a state of war among the princes of the various states. You might as well not attend.
