《史记·三十世家·魏世家》
如果不保存韩国，东西二周、安陵必定危险，楚国、赵国大败之后，卫国、齐国就很害怕，天下诸侯都向西奔赴秦国去朝拜称臣的日子没多久了。
今不存韩，二周、安陵必危，楚、赵大破，卫、齐甚畏，天下西乡而驰秦入朝而为臣不久矣。
If Han is not preserved, Western Two-Zhou and Anling would certainly be in danger. After the great defeat of Chu, Wei and Qi would be more frightened. The day would not be too far when the princes of the world would flee to the West to pay their respects to Qin and accept Qin as their lord.
