1. Since China UnionPay has directly cooperated with Korea BC Card Company, the largest credit card company in Korea, there is no charge for spending credit cards through UnionPay network in Korea. However, if you use other international card networks such as VISA, the fees they charge vary from 1~2%.

2. There are roughly two situations in terms of exchange rate. When taking the UnionPay network, the exchange rate in the card will be directly settled into RMB according to the standard exchange rate of China UnionPay on that day and deducted from the card. When taking other international card networks such as VISA, the won will be settled into US dollars first, and then into RMB. I hope to adopt.
