Dear Valued Customers and Friends,

Thank you for your long‑term support.

To further improve communication efficiency and service quality, our company will update the corporate email domain. The old domain @chinaqy.onaliyun.com will be replaced with the new domain @treeinco.com.

During the transition period (July 10, 2026 – July 10, 2027), the old email accounts will only retain incoming mail capability to ensure continuity of historical business correspondence. The old domain will be permanently deactivated upon the expiry of the transition period.

Both old and new corporate email addresses can receive your emails effective immediately. For smoother business communication, we recommend adding our new email addresses to your contact list at your earliest convenience.

Thank you again for your support and trust in our company.
