The method is as follows:

1. Contact the bank’s customer service: Call the customer service number of Bank of China Hong Kong to inquire about the progress of the credit card application and card delivery status.

2. Check the express delivery information: The bank has sent the card, and you can check the express company's mail tracking information to understand the card delivery status.

3. Reissue the card: If the card is lost or fails to be delivered in time, you can contact the bank customer service to apply for a replacement card. Usually the bank will ask you to provide some personal information and supporting documents to ensure the security of the card.

4. Cancel application: If you have not received the card for a long time and have not received a response from the bank, you may consider canceling the credit card application and seeking a credit card application from another bank.
