1. identification: usually an id card. The applicant 18~65 years old, and the soldier should provide a copy of the military certificate;
2. Work certificate: it can be the original work certificate issued by the employer (please indicate the specific company name, department, position and income, and affix the official seal or personnel seal of the company), or it can be a copy of the work permit verified and marked by the sponsor;
3. Proof of financial resources: it can be a payroll record issued by a bank, an income tax withholding certificate, or a market value certificate of a house, a car, a deposit or an investment (such as a copy of the real estate license/car driving license/bank time deposit certificate) and other materials that can prove your economic level.
You can choose to apply for a credit card directly at China Merchants Bank in official website, or you can go to a bank outlet. You can also contact a salesman to come to your door and choose a formal channel. I wish you early success.
