A student's family or friend can scan the QR code to pay for the student with their personal Weixin Pay account.
Please note that the Weixin Pay QR code generated on your payment page can only be scanned once. Once any payer has scanned the code for the payment, it will not be allowed to change to another payer to re-scan the QR code again.
If you would like to change another payer after the QR code has been scanned once, you have to cancel the current booking and create a new payment booking for your payment.
