The meaning of other cards in the clubhouse:
Brand A, brand T, brand Q, brand M and brand V are actually different categories for different face values and service items. Often, the service content and price provided by each brand of the same type are different, just a code name, which has no practical significance.
If you often go to clubs and get familiar with one, you can distinguish different items next time without telling each other one by one, which is convenient for ordering. Although the names are the same, the definitions and service contents of each family are different.
