In China, RMB settlement can be realized through UnionPay. After going abroad, you can spend and withdraw cash at ATMs of merchants and banks that support visa, MasterCard and JCB, and settle in corresponding US dollars or Japanese yen.
In addition to the above-mentioned settlement function, dual-currency credit cards are no different from ordinary credit cards, but more convenient for some friends who often need to go abroad, so the application conditions are the same as ordinary credit cards, so feel free to apply boldly!
