My cards are from HSBC and Guangfa Bank. When I called their customer service, they didn't know anything about PIN codes. What should I do ?

Don't worry about the PIN code, I use CGB and BOC credit cards, six-digit ones are fine.
Just enter your 6-digit password, some gas stations only require 4 digits.
Pin code is the personal identification number, which is also known as a password. If the password is six digits, regardless of the machine requiring only four digits, you can usually enter it in sequence.
