Go to the bank to find some questions about distributing money! If you understand, please come and answer, ok?

The bank is obliged to exchange money for you ... this business is free!

But only if the bank has change. Generally, larger outlets are ok, and some smaller ones occasionally have no change.

If you want to change new money, you need to ask in advance. After all, banks can't prepare all kinds of new money for people to change every day!

If you want to change new coins, you can go to the People's Bank and ask!
