It takes 5 working days for ICBC to report the loss and reissue the credit card, and 7 working days for mailing (excluding Saturday and Sunday). It takes a week for Bank of Communications to reissue a new card after reporting the loss. Generally, it takes one week for China Bank to reissue a new card and mail it to you, and the Postal Savings Bank can reissue it after 7 days of reporting the loss.
If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
