If you want good service, go to China Merchants Bank. You know that ICBC is the boss, but they have a bad temper and don’t have much patience to serve. Dual currency is easy to handle. If you are applying for it for the first time, it is best to provide proof of salary and income, which will help to approve the card.

In fact, the most useful thing is to have a large fixed deposit in the bank where you apply for the credit card. In this way, they will approve a higher credit limit for you, proving that you have financial strength and repayment ability.

In a word, provide what is most beneficial to you. If you have a good job, you can get a work certificate. If you have a high income, you can get an income certificate. If you have a lot of deposits, just go directly to apply (China Merchants Bank and Industrial and Commercial Bank both recognize this). Others include academic qualifications, household registration, etc.
