《韩非子·初见秦》
这个时候，用兵追歼楚军，就可占领楚国；既可占领楚国，楚民就足以归我所有，楚地就足以归我所用，向东面可进而削弱齐、燕，在中原可进而侵凌韩、赵、魏。
当此时也，随荆以兵，则荆可举；荆可举，则民足贪也，地足利也，东以弱齐、燕，中以凌三晋。
At this time, the soldiers pursued and annihilated the Chu army, and they could occupy the State of Chu. If they could occupy the State of Chu, the people of Chu would be mine, and the land of Chu would be mine. I could move eastward and weaken Qi and Yan, and I could move in the Central Plains and invade Han, Zhao, and Wei.
