If it is a debit card, the initial password may be 5-digit customer service hotline plus 0. This password must be changed, and the password must be changed at the branch counter. Ask the staff of the outlets specifically.
If it is a credit card, there is no initial password. After receiving the card, you need to dial the customer service hotline on the back of the card and set the password. You can also activate the card and set the password at the financial counter of the local CCB outlet.
