《汉书·传·贾邹枚路传》
公孙获于是去谒见梁王，对他说： 济北国束与强齐接壤，南与吴、越为邻，北面受燕、赵胁迫，为四面受敌之地，权轻不足以自我防卫，势弱不足以抵御边寇，又没有奇才异计以御难，虽然一度失言，答应归附吴国，其实并不是济北王的本意。
公孙玃遂见梁王，曰： 夫济北之地，东接强齐，南牵吴、越，北胁燕、赵，此四分五裂之国，权不足以自守，劲不足以扞寇，又非有奇怪云以待难也，虽坠言于吴，非其正计也。
Thereupon, Gongsun Huo went to meet with the King of Liang and said to him: "Jibei is bordered by powerful Qi to the east and also neighbors Wu and Yue to the south.  To the north, it is threatened by Yan and Zhao.  It is a land attacked by enemies on all sides.  Its power is weak; it is insufficient to defend itself.  Its authority is feeble; it is insufficient to resist border bandits.  It has no remarkable talents or unusual plans to protect itself from danger.  Although it was briefly misled and agreed to submit to Wu, in fact, this was not the King of Jibei's true wish.
