《史记·七十列传·张仪列传》
秦国使韩国屈服，进而攻打魏国，韩国害怕秦国，秦、韩合为一体，那么魏国的灭亡，快的简直来不及坐下来等待啊。
秦折韩而攻梁，韩怯於秦，秦韩为一，梁之亡可立而须也。
The State of Qin forced the State of Han to surrender, and then attacked the State of Wei. The State of Han was afraid of the State of Qin. The State of Qin and the State of Han united. Then the destruction of the State of Wei is so fast that there is no time to wait and see.
