If any Services fail to conform to the foregoing warranty, Cagun shall, as its sole obligation and the Client's exclusive remedy, re-perform the non-conforming Services at no additional charge, provided that the Client notifies Cagun in writing of the non-conformity within thirty calendar days after performance of the relevant Services. This warranty is void if the non-conformity results from the Client's acts, omissions, or failure to follow Cagun's reasonable instructions.

Except as expressly set forth in these Terms or any Service Agreement, the Services and the Website are provided on an as is and as available basis without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

Cagun's total aggregate liability arising out of or related to these Terms, the Website, or the Services, whether in contract, tort, or otherwise, shall not exceed the greater of (a) the total amount of fees actually paid by you to Cagun during the twelve-month period immediately preceding the event giving rise to the claim, or (b) one thousand United States Dollars (USD 1,000). The existence of multiple claims shall not enlarge this limitation.

10. Indemnification

You agree to defend, indemnify, and hold harmless Cagun, its affiliates, and their respective officers, directors, employees, contractors, and agents from and against any and all claims, damages, obligations, losses, liabilities, costs, debts, and expenses (including reasonable attorneys fees) arising out of or related to your use of the Website or Services, your violation of these Terms, your violation of any rights of a third party, or your violation of any applicable law, rule, or regulation.

Cagun shall promptly notify you of any such claim, provide you with reasonable cooperation and assistance in the defense of the claim at your expense, and permit you to assume sole control over the defense and settlement of the claim, provided that you shall not enter into any settlement that imposes any obligation on or admits any liability by Cagun without Cagun's prior written consent.

Each party shall bear its own costs of negotiation, mediation, and litigation, unless otherwise ordered by a court of competent jurisdiction.

16. Governing Law and Jurisdiction

These Terms and any dispute arising out of or in connection with them shall be governed by and construed in accordance with the laws of the People's Republic of China, without giving effect to any choice or conflict of law provision or rule that would require the application of the laws of any other jurisdiction.

The United Nations Convention on Contracts for the International Sale of Goods shall not apply to these Terms or any Service Agreement. Any legal suit, action, or proceeding arising out of or related to these Terms or the Services shall be instituted exclusively in the competent courts located in Hefei, Anhui Province, People's Republic of China. You waive any and all objections to the exercise of jurisdiction over you by such courts and to venue in such courts.

Notwithstanding the foregoing, Cagun may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property rights or Confidential Information, and you consent to the personal jurisdiction of such courts for that purpose.

17. Severability

If any provision of these Terms is held by a court of competent jurisdiction to be invalid, illegal, or unenforceable for any reason, such provision shall be eliminated or limited to the minimum extent necessary, and the remaining provisions of these Terms shall continue in full force and effect. The parties shall negotiate in good faith to replace the invalid, illegal, or unenforceable provision with a valid provision that most closely approximates the original intent and economic effect of the invalid provision.

The invalidity of any provision shall not affect the validity or enforceability of any other provision of these Terms, all of which shall remain in full force and effect. If a court finds any provision of these Terms to be excessively broad in scope, duration, or geographic coverage, the parties agree that the court shall reform such provision to make it enforceable to the maximum extent permitted by law.

18. Waiver

No failure or delay by Cagun in exercising any right, power, or privilege under these Terms shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege preclude any other or further exercise thereof or the exercise of any other right, power, or privilege. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party.

The rights and remedies provided in these Terms are cumulative and not exclusive of any rights or remedies provided by law or equity. Any waiver of any breach of these Terms shall not be deemed a waiver of any subsequent breach of the same or any other provision.

19. Entire Agreement

These Terms, together with any Service Agreements, the Privacy Policy, and any other documents expressly incorporated by reference, constitute the sole and entire agreement between you and Cagun regarding the subject matter hereof and supersede all prior and contemporaneous understandings, agreements, representations, and warranties, both written and oral, regarding such subject matter.
