III. Security Tips for E-mail Contact
1. Official emails of our company used for external communication end exclusively with “@tongwei.com”. Please ensure you thoroughly verify the sender’s email address.
2. For critical issues such as changes to banking information or contract approvals, confirm both the sender’s email domain and contact information. If necessary, reach out to us directly through the official hotlines or email addresses provided above in the “List of Official Channels”.
IV. Security Tips for Official Website Access
1. Please access the official websites of our company by typing the URLs directly into your browser’s address bar. Avoid clicking on suspicious links.
2. Product information, announcements, and contact details published only on the official websites are the sole authoritative sources. Information obtained via other non-official channels is used at your own risk.
V. Safety Tips for Fund Transfer
1. Our company will never proactively announce changes to bank account details via non-official emails, telephones, social media, or unauthorized channels. Any changes to the account details require written notification signed by our Finance Department and are issued only via designated official channels.
2. Upon receiving any request to change bank account details, for your fund security, always independently check and verify via the official hotlines or email addresses provided above in in the “List of Official Channels”. Do not proceed with payment operations to the new account based on this request without prior confirmation.
VI. Rapid Response to Suspicious Incidents
1. If you receive suspicious emails, links, or notice any tampering with communication channels, immediately cease further actions and report to our company promptly via the official hotlines or emails provided above in the “List of Official Channels”.
2. We recommend all partners enhance information security, regularly update passwords and enable two-factor authentication to reduce risks of cyberattacks.
VII. Legal Liability and Follow-up Support
1. We reserve the right to pursue legal action against the act of committing fraud through the use of forged Tongwei communication channels, and we will cooperate with judicial authorities to hold the responsible parties accountable.
2. Should any losses occur due to such fraudulent activities, our company will, based on the situation, provide necessary legal assistance to jointly uphold market order and trust for cooperation.
Tongwei is committed to its mission “Tongwei For Better Life” and is dedicated to providing safe, reliable products and services for global users. We thank you for your trust and support—and encourage continued vigilance in jointly safeguarding information security.
