Great Wall RMB cards are issued by branches, and different branches have different policies. International cards are issued by Hong Kong card companies, and annual fees are mandatory, and UnionPay channels cannot be swiped. In the past, the only advantage was that it was independent of these two types of cards and could use BOC deposits and deposits (now all types of cards can be used). Now the Great Wall card is gradually being collected, and the 60th anniversary card is actually a Great Wall card with the name of BOC.

The Bank of China series is issued by the head office, and there are two kinds of RMB single currency and dual currency.

There is no difference between these two cards except the customer service phone number, and then there is no difference between the Great Wall card and the quasi-credit card, and it doesn't matter whether it is high or not.
