After purchasing goods in Kuaishou installments with Alipay Huabei, if you need to return them, you can follow the following steps to repay the Huabei installments:

1. First, contact Kuaishou customer service and explain Reason for return and request for return.

2. After Kuaishou has approved the review, send the goods back to the address designated by Kuaishou.

3. After the return is successful, you can log in to Alipay and find the repayment bill on the Huabei page. If the bill amount is 0, it means that the return has taken effect and no repayment is required.

4. If the bill amount is not 0, it means that the return has not yet taken effect and repayment is required. You can choose to repay in full at once or according to Huabei's installment plan.

5. Click on the corresponding repayment option and follow the prompts to complete the repayment operation.

6. After repayment, wait for the Alipay Huabei system to update the billing information.

7. After confirming that the bill information has been updated, you can check again whether the bill amount is 0. If it is 0, it means that the return has taken effect and the repayment operation is completed.

Summary: Through the above steps, you can return Huabei after shopping on Alipay, and repay the Huabei installments accordingly. Please note that frequent loan applications or loan operations may increase personal credit risk. It is recommended to check the personal credit risk index before applying for a loan to avoid application rejection.
