In terms of processing methods, you need to fill out the form through CCB outlets and bring your ID card when applying. Proof of work income (work permit, employment certificate, salary card (preferably more than 3 months), tax bill, social security bill, provident fund bill for the last 3 months, etc., not all of which are required, but you can have them), car production certificate in my name (driving license, car purchase invoice, etc.), and if you can attach some financial proof, such as time deposit certificates of real estate and CCB, it will be very helpful to get off the card. (If the proof of work income can't be provided perfectly, it's best to have proof of financial resources)
And the whole approval time of his credit card takes about 2-25 working days, which is like a month. The landlord can know the approval progress of your card through the "application progress query" on his credit card homepage.
If the landlord has other questions, you can ask them.
