Generally speaking, banks won't handle credit cards for people who don't have jobs, because banks are worried that you won't be able to repay, so you need to provide some certificates of your fixed assets to the banks to prove that you are able to repay, such as real estate licenses.

Another way is to use a credit card, which means that if you have a credit card in other banks, you can indirectly prove that you have certain repayment ability, and you can go to banks such as Bank of China and Bank of Communications.
