《金史·列传·卷三十九》
承晖秘密派人用矾写奏章报告说： 七斤已经投降，城内没有坚定的斗志，我虽以死守城，怎么能保持长久。
承晖间遣人以矾写奏曰： 七斤既降，城中无有固志，臣虽以死守之，岂能持久。
Cheng Hui secretly sent someone to write the report about the city in alum: Qi Jin has already surrendered, and the city is not united in resisting. Even though I will defend the city to the death, how can I possibly last forever.
