《三国志·吴书·诸葛滕二孙濮阳传》
从前战国时期，诸侯各自依恃兵强地广，互有救援，认为这样可以将政权传与后世，他人不能危害。
昔战国之时，诸候自恃兵强地广，互有救援，谓此足以传世，人莫能危。
In the past, the Warring States was a period when the feudal lords relied on their army and territory to assist each other, thinking this was the way to pass on their regimes to future generations and preserve themselves from the dangers of others.
