There exists one uniform system of measures and weights that counts for all of the country. But little merchants and hagglers often work with inaccurate weights and measures. It's true that in each province a strict control is being practiced, but obviously the deceit that is committed with counterfeit weights and measures, is never to be wiped out. In the rest of the country for the wholesale, small blocks of silver are being used as a means of payment. These exist in various weights.
Retailers manage with rice and linen as a means of payment.
