CCB outlets apply, which is the traditional way to apply for credit cards. When applying, you should bring your ID card, proof of work income (company 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. These are not necessary, but you can have them. If you can attach some economic certificates, such as real estate, automobile production, time deposit certificate of China Construction Bank, then (in the case of not providing perfect proof of work income, it is best to have proof of economic source. )
Of course, now you can also apply for a credit card through online channels, such as mobile banking, WeChat and CCB credit card website. No additional proof of payment is required. Banks will focus on the landlord's real estate, social security, provident fund, individual tax, personal credit and so on. If these efforts are not much or not much, this method is not recommended.
