Where can I exchange money when I'm traveling abroad?

pu1. Usually, KEB has the best exchange commission rate.
Or you can find it if you search for a preferential bank for exchange fees.
If my house is in Seoul, there are a lot of houses in Gangnam...
If you go there, you'll get preferential exchange

OK

pu2. In my case, when I go abroad, I exchange money a little and bring my Citibank card
There's a Citibank International Card. If you have it, you can withdraw it from abroad
If you have that card, you don't have to carry a lot of money and the exchange fee is cheap, so I like it

OK

pu3. I want to exchange money at the bank I usually do business with, but if I ask for preferential treatment, they lower the exchange fee.
The main bank is comfortable
