Dear xxx (write the name of the other party's contact person here, and write Mr./Mrs. if you don't know),
I come from Beijing, China. Can I understand why I can buy your products from your sales channels in the United States instead of the distributors in China? What's the cost? Do you provide Chinese consulting services? How can I know that your product suits me best?
I look forward to your early reply. Thank you.
Best regards,
