Card friends!
The direct answer to your question is: Of course you do! Apply for a credit card from any bank, including your intended bank, China Guangfa Bank. Applicants must provide basic supporting materials, including true and valid proof of identity, proof of fixed employment (working somewhere for a certain number of months/years), and proof of relatively stable income.
If you want to apply for a credit card with a higher credit limit, just the above-mentioned supporting documents are not enough. You also need to provide more financial proof, such as proof of fixed assets, including real estate certificate and driving license. The more you can demonstrate your financial strength, the better your credit card limit will be.
