《元史·列传·卷六十二》
受赐田产之家，各任土著奸吏为庄官。这些征收租税的人称为催甲斗级，他们巧立名目向人民搜括；还差人向州县索取每月的俸禄，而自己应交纳而未交纳的国赋，不肯交纳，变卖归己，官府无不愤慨，农民被迫逃亡。
其受田之家，各任土著奸吏为庄官，催甲斗级，巧名多取；又且驱迫邮传，征求饩廪，折辱州县，闭偿逋负，至仓之日，变鬻以归。官司交忿，农民窘窜。
Land-granting families have employed treacherous local officials as manor administrators. These tax collectors, called "催甲斗级," establish specious pretexts to extort the people. They also send people to the prefecture and county governments to demand their monthly salaries, but they refuse to pay the taxes, which they sell as their own. This has angered the government beyond measure and forced the farmers to flee.
