Eurasia Dragon Card is a dual-currency credit card jointly issued by China Construction Bank and Changchun Eurasia Group. In addition to all the functions of a credit card, it can also enjoy some benefits of Eurasia Group.
The Hong Kong, Macao and Taiwan travel card can be used for payment in RMB at home and abroad. All foreign currency transactions (including consumption, withdrawals, etc.) will be converted into RMB and recorded in RMB. There is no currency exchange fee for cross-border transactions, so it is also very good.
Both of these cards are pretty good. It's just that the functions of the credit cards themselves are the same, but some small rights and promotions may sometimes be different. You can apply according to your preferences.
