Credit card tax refund is more convenient, because if you choose cash tax refund, you can get the cash in your hand. If you change the currency of your country when you go back to China, there will be corresponding exchange loss. If you refund the credit card tax, you can directly refund the corresponding money to the credit card, which is equivalent to returning a certain amount of tax refund.

However, there is actually a big hole in the credit card tax refund. The tax for tax refund is actually calculated in euros. However, when you return to your credit card, if your credit card is a dual-currency credit card with USD and RMB, there will also be an exchange rate loss between EUR and USD. If your credit card is a UnionPay credit card, the exchange rate for tax refund is actually different.
