《宋史·列传·卷一百五十五》
金廷大臣多次站起喝骂赵雄，赵雄无所畏惧，辩词更加有力，最终使金主同意了他的请求，金人将这称为 龙斗 。
其臣屡喝起，雄辞益力，卒得请乃已，金人谓之 龙斗 。
The Jurchen court officials stood up to berate Zhao Xiong many times, but Zhao remained fearless, and his arguments became even more forceful. In the end, he persuaded the Jurchen emperor to agree to his request, and the Jurchens referred to this as the "Dragon Debate".
