《宋史·列传·卷一百七十二》
赵汝谈的料敌策略说 ：祸乱仍在河北，还没到河南，英雄豪杰就选占地形，大盗贼就窥伺财物，金帛和重要的物品都集中在河北，河南没有大川作为险要，想起事有什么凭靠？
其料敌之策曰： 祸乱犹在河北，未遽至河南，盖豪雄择形势，大盗窥货宝，金帛重器俱聚河北，河南无大川为之险，欲起安所凭？
Zhao Rutan's strategy for predicting the enemy was: The chaos is still in Hebei and has not yet reached Henan. The heroes and brave men have already occupied the terrain, and the great thieves are eyeing the wealth. Gold, silk, and important items are all concentrated in Hebei. Henan does not have a great river as a danger. What can we rely on if we want to start a rebellion?
