After using CCB credit card, I can self-check transaction records through mobile banking, WeChat banking, online banking and customer service hotline voice system. Please note that it may take several days from the transaction to the bill (depending on the specific time of settlement between merchants and banks, some merchants will settle accounts soon, and some may take a while).

Of course, the display mode and query mode of each bank will be slightly different. You can also call the bank customer service hotline and ask again.
