If the cardholder wants to apply for another credit card with his existing credit card, he usually needs to use the original credit card for more than 6 months before he can apply for another credit card in another bank. For China Bank, it takes a relatively short time to apply for a card, and the credit card holders of China Bank can apply for a card as long as they use the card for more than 3 months.

Under normal circumstances, the cardholder can take the original credit card as proof of financial resources and show the original ID card, so that he can apply for another credit card in another bank on the basis of the original cardholder's card. For some banks, if they want to handle the card business, they may also be required to submit a copy of your ID card, a copy of your credit card, proof of financial resources and other related information.

However, it should be reminded that it is a good thing for cardholders to get a card by doing more cards, which means more money can be overdrawn, but it will also bring some troubles. If the cardholder improperly manages his credit card, resulting in excessive cyclic overdraft, then the trouble is relatively big. If the cardholder fails to repay after the repayment date, the credit debt of the cardholder will snowball, which will cause great trouble to the personal economy.

So I suggest you consider this matter carefully, or give priority to your personal spending power and repayment ability.
