According to the picture, the landlord needs to ask "Do you have our credit card?" After selecting the city and handling the card type, click Next, fill in the personal information and submit the application as required, without filling in the CCB credit card number.

On the other hand, if the landlord chooses "Yes", then the website will default that the landlord has a CCB credit card and naturally ask you to fill in the card number.

If the landlord has other questions, you can ask.
