You can't. The loan itself does not support credit card repayment. Credit card is a kind of credit consumption card. If you can repay by credit card, it is equivalent to cashing in a loan, which is absolutely not allowed.

In addition, if you withdraw cash from a credit card and then repay it with a debit card, there will be problems. Credit card withdrawal is a cash installment, and banks have a clear purpose of cash installment loans, which can only be used for consumption. If it is found to be used to repay the loan, it is a breach of contract and the bank will never allow it.

Can I transfer my credit card to WeChat?

I can't. Credit card transfer function is regarded as credit card cash withdrawal. At present, only the other party's savings card transfer is supported. In other words, users can use credit cards to transfer money to their peers' savings cards, but they can't give change to WeChat transfer, nor can they use credit cards to send red envelopes to WeChat for cash withdrawal.
