When applying for a credit card through a bank branch, you generally need to bring your ID card and proof of assets, such as real estate, cars, bank time deposit certificates, financial management, etc. This will be very helpful for applying for the card.

Nowadays, most banks can also apply for cards through online channels, such as mobile banking, online banking, official WeChat, official credit card websites, etc. (I use China Construction Bank, and applying for cards on their website is more convenient than applying at branches. There are a lot of them. The main reason is that they have enough outlets, convenient repayment, and they have a lot of activities recently, so they are good to use.) You might as well give it a try.
