《资治通鉴·汉纪·汉纪七》
得到高等爵位和免除罪名，是天下百姓最迫切的欲望；让天下人输送粮食到边境地区，以换取爵位、免除罪名，不用三年时间，边塞的粮食储备就必定会很多了。 
夫得高爵与免罪，人之所甚欲也；使天下人入粟于边以受爵、免罪，不过三岁，塞下之粟必多矣。 
To attain high ranks and have punishments pardoned are the most urgent desires of the people under heaven; let the people under heaven transport grain to the border areas in exchange for rank and the pardon of their punishments, and in less than three years the storage of grain at the border will definitely be plentiful.
