1. ISO currency codes.
CNY is the ISO currency code for China's currency, the Yuan Renminbi, when it is traded onshore.
'CN' refers to China.
'Y' refers to Yuan.
The abbreviation 'RMB' is also widely used for the Chinese Yuan Renminbi, meaning exactly the same as CNY.
However, RMB is not the ISO code.
CNY is also an abbreviation for Chinese New Year.
It is also known as the Lunar New Year, and falls between January 21 and February 20.
