I received a short message from CCB credit card saying that it was not real consumption.

Did CCB send a message saying that your transaction is abnormal, please use your credit card in compliance? Receiving this message means that there is something wrong with your transaction, and most of them are suspected of TX. You'd better pay attention. Now it's just a warning. If you continue, the card will be severely stopped ~ it is best to brush it in different merchants, supermarkets, restaurants and department stores, which requires real transactions.
