It mainly depends on whether your credit status meets the conditions for issuing cards by banks. If you have many personal credit loans and many overdue times, it is very likely that your credit card will not work. Or if you don't have a fixed income, then credit cards are also difficult.
Summarized the card handling methods of the following banking channels:
First, to apply for a card through a bank outlet, you should bring your ID card and proof of work income (usually including: work permit, employment permit, salary card (preferably more than 3 months), tax bill, social security bill, provident fund bill for the last 3 months, etc. None of these are necessary, if you have any). If you can attach some financial certificates, such as real estate, automobile production, bank time deposit certificate, financial management, etc.
Secondly, some banks can apply for cards through online channels (I use CCB, and it is much more convenient to apply for cards on his website than at other outlets, mainly because he has many outlets, convenient repayment, and a lot of activities recently, which is easy to use). it wont hurt you to try it
