Friends, thank you for the invitation. First of all, I want to explain that whether a credit card is a scam or not mainly depends on whether you have over-consumed and used the card. If this is the case, then no card is suitable for you. I also use Shanghai Pudong Development Bank's card, and the limit is relatively good. But one thing I want to remind you is that you'd better not use the Wanyongjin business. The interest rate can be said to be usury. A friend of mine used it, and it took three years for him to pay off his debt. For more tips on using credit cards, please leave a message to exchange.
