Refund policy

Here is the revised return policy section in English, incorporating your request to prohibit unauthorized returns and emphasize the requirement to contact customer service first:

Return Process (Revised)
To request a return, you must first contact our customer service team via email. Please follow the steps below:

1.  Contact Customer Service: Email us at 18055871599@163.com with your order number and reason for return.
2.  Consultation & Approval: Our team will work with you to review your request and confirm if your item is eligible for a return.
3.  Receive Instructions & Label: If your return is approved, we will provide you with the return shipping address and a prepaid return label, along with detailed instructions on how to send your package back.

Important Notice
• Returns sent without prior authorization will not be accepted. We reserve the right to refuse any unauthorized returns.

• Please do not ship items back to any address before receiving an authorized Return Merchandise Authorization (RMA) number or a valid return shipping label.

Please let me know if you would like to adjust the tone (e.g., more strict or more accommodating) or integrate this section into the full policy document.
