How did the money from WeChat go to Alipay?

I think we can withdraw cash from WeChat to the bank card, and then transfer it from Alipay to WeChat account or pay by QR code scanning. Make sure that the account is bound with a bank card, and select the change in WeChat to enter the amount for withdrawal, and it will arrive in a few minutes. Select transfer in Alipay, enter the amount, and verify the payment password after checking the information is correct.
