《金史·列传·卷四十四》
刘豫见人数太多，便更改为五等税法，但民众仍然认为赋税过重。齐国被废以后，梁王宗弼主管行台省事，范拱是他的属官。宗弼访查对民众有利和有害的事情，范拱请求减少百姓的赋税，宗弼听从了，百姓所交纳的赋税减少了三分之一，民众这才获得喘息之机。
臣所管已拨深泽县地三百余顷，复告水占沙碱者三分之二，若悉从之，何时可定。
Liu Yu thought the number was too big, so he changed to the five-level tax law, but the people still thought the tax was too heavy. After Qi was abolished, the Prince of Liang, Zongbi was in charge of the matters of government offices, and Fan Gong was his subordinate official. Zongbi asked about the good and bad things about the people, and Fan Gong asked him to reduce the tax for the people, Zongbi listened to him, and the tax paid by the people was reduced by one third, and people finally had a chance to rest.
