《北史·列传·卷十五》
李用了范鉽提出的计策，他们让千里之外的百姓，每户都到官仓交纳粮食，并使他们停留在路上，李故意推延日期，百姓们争着行贿，都请求能先交粮，于是各处百姓们都感到困乏疲惫，路边人群议论： 养活这些搜括民财的人，不如养活强盗去做大臣。 
用范标陈策计，令千里之外，户别转运，诣仓输之。使所在委滞，停延岁月。百姓竞以货赂，各求在前，于是远近大为困弊。道路群议曰： 畜聚敛之人，未若盗臣。 
Li Wei used the strategy proposed by Fan Yan. They forced people thousands of miles away to deliver grain to the official warehouse and delayed them on the way. Li Wei deliberately postponed the date, and the people struggled to bribe him, all requesting to pay the grain first. As a result, people from all directions felt exhausted and tired. The crowds along the road said: It is better to support bandits as officials than to support those who plunder people's wealth.
