I want to ask if the PIN code of the credit card needs to be set separately? When I went to China Merchants Bank this morning, the staff there said they don't set it, and if needed, just enter the first four digits of the query password ?

CMB's password is six digits.

Yesterday I filled up at the gas station. The six-digit card password I entered was successfully deducted. Before entering the first four digits of the password, it didn't work. Try a few more times later. Someone can also enter four digits. It may be different for each bank.
