Answer 1

The Chinese use a currency called the "Yuan." There is only one official type of currency in China.

Most countries trade in any type of currency because their banks can change the currency into the local currency.

Answer 2

The Chinese 'dollar' is the Yuan....same as the Japanese Yen , English Pound Sterling, EU Euro, and so forth.
