This tutorial is written based on our Bank of China experiences. Other banks may be different (but generally similar). Foreign exchange is an exchange of currencies at an exchange rate. The rate between currencies changes by the minute or second.

Prepare these things:

1] Passport
2] Your Address
3] Foreign Exchange Currency
4] A secure folder or bag to put receipts and cash in, as the cash may be too thick to fit in your wallet.

Find the address of a bank [link: bank addresses] that you would like to use.

When you arrive:

1] Get a ticket by selecting "Personal Banking".

2] Tell the people at the front desk to exchange money.

They will give you a form, which is available in English. Ask for the English version.
("Exchange Memo")[image of form]

3] Fill in the form:
After filling in your personal information, you can probably just fill in the amount that you want to exchange, the rest is filled in by the teller.

4] Give the teller the form, foreign currency and your passport.
Keep the receipt for converting back to the original currency when you leave the country.
