Here is a little gem from the Gerson Lehrman Group,
Many people don’t know this, but China was the first country in the world to use a true fiat paper money currency system during the Yuan Dynasty from 1271-1368. The name of this currency was called the Chao. Eventually, the Chao collapsed due to excessive inflation and rampant printing of money. China’s current money-supply is of deep concern to many, even its own economic advisors, who often must comment with a limited amount of negativity regarding their own economy.

A fiat currency collapsed, you say? Who woulda thunk?
Interesting that the collapsed currency of the Yuan Dynasty was the Chao. Now we have the controlled economy of China’s fraud currency called the Yuan.
