蘇秦
Chapter 250 of the "Zhanguo ce" records how another School of Diplomacy strategist Su Qin (380-284 BCE) persuaded Li Dui (李兌), the Chancellor of Zhao, to provide Mr. He's jade-disk in order to acquire funding for the Vertical Alliance of six states against Qin. During their first audience, Su Qin convincingly explained his Vertical Alliance strategies to Li Dui and said, "You killed your ruler, [i.e., King Wuling of Zhao], and you extirpated his kin, and find your position in the empire as perilous as though you were perched atop a pile of eggs. If you heed my plans you will live; if you heed them not you will die." After Li told Su to return on the next day for an audience, one of his attendants said Su's "arguments and their scope are beyond you. Will you be able to do as he advises?" Li replied that he could not and followed the attendant's suggestion that he plug up his ears in order to avoid listening to Su's rhetoric. Su Qin persuasively spoke for the entire day during the second audience with Li. When the attendant escorted him out, Su asked "A day ago I spoke only crudely and your ruler was moved. Today I spoke in detail and he was not. Why?" "Your plans are great and their scope is lofty, sir", replied the attendant. "My lord cannot use them, so I asked him firmly to stop both his ears so that he would not heed what was said. However, come again on the morrow and I will ask that the Master be well rewarded." During the final audience, Li Dui gave Su Qin "a moon pearl [秦明月之珠], the Jade of Ho [和氏之璧], a black sable coat and a hundred pieces of pure gold." Thus, Su got the wealth he needed in order to go westward into Qin state.
