《左传·昭公·昭公十六年》
齐国的国君无道，起兵攻打远方的国家，会见了他们，缔结了和约而回来，没有人能够抵御，这是由于没有霸主啊！《诗》说， 宗周已经衰亡，无所安定。
齐君之无道也，兴师而伐，远方会之，有成而还，莫之亢也。无伯也夫。《诗》曰： 宗周既灭，靡所止戾。
The ruler of Qi is ruthless. He raises an army and attacks distant states. He meets with them and makes peace treaties when he returns. No one can resist him. This is because there is no hegemon. The Classic of Poetry says: The Zhou Dynasty has declined and is no longer stable.
