What is the currency of the Asian giant?

We are very used to traveling in Europe without having to worry about the currency with which to pay. And is that thanks to the project of the European Union, several member states have the same currency, the euro (€), so when we go to neighboring countries we do not even worry about this matter.
However, if we go a little further, we will have to take this factor into account when packing. It is true that in most cities, especially in the most touristy ones, you will find currency exchange offices, but it is possible that commissions will apply to you.
If you want to be more secure, check with your bank how to get yuan and, if you are going to pay with a card, be careful with the commissions!
The yuan (¥) or renminbi is the currency of the Federal Republic of China . As you know, the equivalence between the currencies changes every day, but it could be said that approximately 1 EUR = 7.8 CNY.
