《明史·志·卷五十七》
明朝初期务求简易，此后增加设置渐渐变多，出行要送财物，停留从事买卖也要送财物，经过的地方居留的地方各自有税。
明初务简约，其后增置渐多，行赍居鬻，所过所止各有税。
In the early Ming Dynasty, simplicity was pursued, but after that, the number of additional settings gradually increased, and travelers had to give gifts to go out, and those who stayed to do business also had to give gifts, with each place passed through and each place stayed subject to its own tax.
