Of course, if it is not a credit card but an ordinary bank card, there will be a cross-regional handling fee.

Answer to the supplementary question: I don't quite understand what you said about "the income of China Agricultural Bank". What is the relationship between university tuition and ABC? If the business of charging tuition in your school is undertaken by China Agricultural Bank, what does this have to do with your credit card? Credit cards cannot be transferred, and there is no regional fee for consumption (visa 1.5% in different currencies abroad). Before paying, make sure that the school is talking about a credit card. If it is an ordinary bank card or debit card, it is equivalent to transfer and remittance, and it needs to be charged across regions. If it is a credit card, the acquiring unit is a shopping mall, a school or a bank, and there is no handling fee.
