《战国策·秦三·范子因王稽入秦》
如果大王觉得臣的话说得对，就请大王依照这些执行，臣自信这些有利于国家政治。如果认为我的话不对，那臣即使久留于秦也没有什么作用。
使以臣之言为可，则行而益利其道；若将弗行，则久留臣无为也。
If the king thinks what I said is correct, please act accordingly, and I am confident that it will benefit the country's politics. If you think what I said is wrong, then even if I stay in Qin for a long time, it will be useless.
