《元史·列传·卷六十》
世祖计划把江南宋朝的宗族及大姓迁到北方来，李劝谏说： 宋朝已归顺大元，其民安于农业，今无故要迁徙，必将引起疑惧，万一有奸人乘机造乱，于国家不利。 
时帝欲徙江南宋宗室及大姓于北方，李乘间言： 宋已归命，其民安于田里。今无故闻徙，必将疑惧，万一有奸人乘衅而起，非国之利也。 
Shizu planned to move the clan and the surname of the Song Dynasty in the south of the Yangtze River to the north. Li advised him, "The Song Dynasty has surrendered to the Great Yuan, and its people are content with farming. Now they are forced to move for no reason, which will inevitably cause suspicion and fear, If the traitor takes the opportunity to cause chaos, it will be detrimental to the country."
