Don't worry, the account balance should change within one month after the ticket is issued. When you enjoy the service, you need to pay. The balance on the card has not changed for the time being because Ctrip's deduction information has not been transmitted to ICBC. Online deduction is not supported for similar transactions such as booking air tickets on Ctrip. Instead, the merchant (Ctrip) will send the deduction account, amount and other information to ICBC for manual or batch bookkeeping.
