Hello, this card friend. First of all, the conditions for applying for China Bank Credit Card are that the applicant must be at least 18 years old, have a stable job and income, and have no bad credit record. If these conditions are met, he can apply for a credit card from China Bank. Because you are self-employed and own a small restaurant, in principle, the success rate of applying for China Bank credit card is relatively low. However, since your monthly income reaches 20,000 to 30,000, and you have more than 200,000 in China Bank, you can submit your business license to the bank, and you can still apply for a China Bank credit card. If the Bank of China passes your application, your credit limit is expected to be optimistic.
