carrying around heavy loads of coins, and started as simple IOUs, but with sometimes dubious worth. Perhaps one of the least desirable earlier systems of exchange was the use of noses! If you didn’t pay your tax, well……you get the point.
Tang people had it easier once they had paper money. Paper money is light, foldable, potentially worth a lot more, and takes less effort to make than many earlier systems.
If the Tang dynasty hadn't invented paper money how would it affect us?
For jobs how would you like to be paid in thousands of pounds of coins? And also in Stop and Shop you'd have to wait hours just to buy a Snickers because everyone in line is pouring out change to pay for their groceries
So you see now that the Tang were great and thank goodness for paper money!
