What is "Chinese Yuan"? Or "Chinese use Yuan." Really? Do Americans not use "Yuan"? Everyone uses "yuan" because "yuan" is not a kind of money. It's a counter.
Money in PRC (People's Republic of China) and ROC (Republic of China) actually have names. In PRC, the name is Renmingbi, or "People's Dollars", and in ROC, the name is Xingtaibi, or "New Taiwan Dollars".
