What does it mean that the bank prompts to send "regional Chinese" information?

Chinese name and address of the area. Sending "regional Chinese" information when prompted by the bank means that the bank needs you to provide or confirm regional Chinese information related to a banking business or operation. This information may include the Chinese name, area code, and the address on the identity document of the area. Let the bank know your location, identity and address more accurately. If you are not sure what information you need to provide, you can contact bank customer service or consult bank staff for more detailed information and guidance.
