《宋史·列传·卷八十三》
与契丹停罢战争，两相修好，李允则即调任知瀛州，他上书说： 朝廷已同意与契丹议和，即要选择好镇守边关的将领，谨守盟约，对于那些认为不应当与契丹议和的人，请都罢去。 真宗说： 这也是我的意思。 迁任西上门副使。
契丹通好，徙知瀛州，上言： 朝廷已许契丹和议，但择边将，谨誓约，有言和好非利者，请一切斥去。 真宗曰： 兹朕意也。 迁西上阁门副使。
After the war between the Song and the Khitan ended, and the two sides restored friendly relations, Li Yuntuo was transferred to be the prefect of Yingzhou. He proposed in a statement: Now that the imperial court has agreed to make peace with the Khitan, it needs to select good generals to guard the borders and strictly observe the treaty. As for those who think that we should not make peace with the Khitan, please dismiss them. Emperor Zhenzong said: It is also my intention. He was promoted to assistant envoy of the West Gate.
