Credit cards of state-owned banks are not recommended. Although ICBC has the largest number of business outlets, its credit card limit is too low. Generally, the credit card limit is between 500 and 5000, and everyone I know approves 500. So it's no use doing it. You can't even buy a mobile phone. Not to mention the Agricultural Bank's credit card. Not everyone can handle it. The requirements are very high and the approval is extremely strict. It is difficult for ordinary staff to pass the examination and approval.
The credit card of China Bank is not bad. The most important thing is that there are many credit card activities in China Bank, which are quite affordable. And it's convenient to pay by installment.
