If you want to change small denominations, call the outlets to make an appointment before 3: 30. There is no limit to the amount. If it is US dollars, you can withdraw a small amount of cash directly at the counter, and you can still get it around 1000.
If you exchange the same currency for the same currency, you don't need to fill out the form. If you buy foreign exchange, you need to bring your ID card to fill out the foreign exchange purchase form.
Not available. Dozens of such small quantities won't provide much.
