《韩非子·存韩》
请允许我去见韩王，让他来晋见，大王接见韩王的时候，趁机扣留他，不要遣返，随后召见韩国大臣，用韩王和韩人交易，就可大量割取韩地。
臣斯请往见韩王，使来入见，大王见，因内其身而勿遣，稍召其社稷之臣，以与韩人为市，则韩可深割也。
Please allow me to meet with the King of Han and ask him to come and pay homage. When Your Majesty receives the King of Han, you should detain him and not send him back. Then you should summon the officials of Han, and use the King of Han and the people of Han to make a deal, so that you can seize a large amount of Han territory.
