县官市木关中，同州岁出缗钱数十万以假民，长吏十取其一，谓之率分钱，岁至数百万，美独不取。
The imperial court bought wood from Guanzhong, and Tongzhou each year provided hundreds of thousands of strings of cash to lend to the people. Local officials took one-tenth of it, which was called "rate-based money". The amount reached several million per year, but only Zhang Mei did not collect this money.
