Most people who come to help you with your credit card calculate the commission based on the number of credit card approvals. It is said that the person who helps you get a card can get a commission of 100 yuan, which is why all shopping malls now recommend you to get a credit card. I have n colleagues. I used to have only one credit card of China Merchants Bank, but I got seven cards at a time. Ask customer service, people say you like that, use that, and stop if you don't like it. But it is also limited to a certain bank. You won't handle multiple banks at the same time. You can go to the website of China Merchants Bank to check if you have your own application information. If yes, it is already being processed. If it is approved, you can get the card.
If you take it from another bank, no problem. Credit cards can be used in any bank. If you just want to use China Merchants Bank's card, you can first open a new card from another bank and then cancel it. That's fine, and it won't affect your credit history. Because almost all credit cards in China are free of annual fees in the first year, there is no need to worry about annual fees.
I hope it helps you.
