Such materials may be protected by copyright, trademark, and other intellectual-property laws.
Nothing in these Terms transfers ownership of those rights to Site users.
20. TRADEMARKS

- War or civil disturbance
- Government restrictions
- Public-health emergencies

Where applicable mandatory law provides greater protection than these Terms, the mandatory requirements will prevail.

These may include a 14-day statutory right of withdrawal, subject to applicable requirements and exclusions.
Such rights may apply independently of our general 30-day return policy.
Nothing in these Terms is intended to restrict mandatory rights available to consumers under applicable law.
29. DISPUTE RESOLUTION
If you experience an issue relating to an order, payment, delivery, return, or refund, we encourage you to contact us first:
We will make reasonable efforts to review and resolve legitimate customer-service concerns.
Nothing in this section prevents either party from exercising legal rights or remedies available under applicable law.
30. GOVERNING LAW
These Terms are governed by laws applicable to Beijing Wanfumokai Technology Co., Ltd., subject to mandatory consumer protections and jurisdictional rights applicable to individual transactions.
To the extent legally permitted, disputes concerning the operation of our business may be submitted to a competent court in:
Beijing, China
Nothing in this provision is intended to deprive consumers of mandatory protections or jurisdictional rights that cannot lawfully be waived.
31. SURVIVAL
Provisions that by their nature should reasonably continue after termination of Site access will remain effective to the extent permitted by applicable law.
These may include provisions relating to intellectual property, existing transactions, liability, dispute resolution, and other continuing obligations.
32. SEVERABILITY
If a provision of these Terms is found invalid, unlawful, or unenforceable, that provision will be interpreted or limited to the extent reasonably necessary and permitted by law.
The remaining provisions will continue in effect where legally possible.
33. NO WAIVER
Our failure to immediately exercise or enforce a right under these Terms does not necessarily constitute a permanent waiver of that right.
A waiver on one occasion does not automatically constitute a waiver on another occasion.
34. ASSIGNMENT
You may not transfer rights or obligations under these Terms where doing so would materially interfere with the operation of the agreement without any required consent.
We may transfer applicable business rights or obligations as part of a legitimate corporate restructuring, business transfer, or similar transaction, subject to applicable law.
Any transfer will not remove mandatory consumer rights associated with an existing transaction.
35. CHANGES TO THESE TERMS
We may update these Terms when reasonably necessary because of changes to:
- Our Site
- Business operations
- Services
- Policies
- Technology
- Legal requirements
The Last Updated date will be revised when a new version is published.
Updates will not be applied retroactively where doing so would unlawfully reduce rights associated with an existing transaction.
