CCB credit card can't send red envelopes through WeChat, because the main function of credit card is overdraft consumption, and it can't directly make online transfer transactions. Online direct transfer will have the risk of withdrawing cash, so banks will impose restrictions. Therefore, if you want to send a red envelope to WeChat, you need to withdraw it with a credit card and withdraw the credit card amount into a savings card. This process is to charge a handling fee of 1%-3%, and interest will be charged from the day you collect it, with a daily interest rate of five ten thousandths.
