《史记·七十列传·春申君列传》
大王一旦同楚国交好，那么函谷关以内两个万乘之国一一韩与魏就要向齐国割取土地，齐国右边济州一带广大地区便可轻而易举地得到。
王壹善楚，而关内两万乘之主注地於齐，齐右壤可拱手而取也。
The king only has to make friends with Chu and the two states with 10,000 chariots each within the Han Valley – Han and Wei – will give land to Qi, and it will become easy to take over the bulk of the Ji Prefecture area to the east of Qi.
