Wechat payment point must be opened first. Enter "Me"-"Wallet"-"Pay Points" on WeChat, and follow the prompts to complete identity authentication and credit evaluation. Select the goods you want to buy in WeChat Mall or other merchants that support WeChat payment, then select the "installment payment" option, and select the number of installments and repayment method according to the page prompts. Confirm the order and installment information on the payment page, and select the payment method for payment. It should be noted that the installment amount paid by WeChat should be paid off before the monthly repayment date, otherwise there will be overdue fees.
