Within the validity period of this Power of Attorney and subject to the restrictions of the laws of China, I undertake to deliver free of charge to WFOE or its designated third party the received distribution of dividends, bonuses or any assets as soon as possible and no later than three (3) days from the date of receipt of such distribution of dividends, bonuses or any assets.

During the period when I am a shareholder of the Company, no matter how the equity proportion I hold in the Company is changed, this Power of Attorney shall be irrevocable and effective from the date of signing the Power of Attorney. If and only if WFOE issues me a written notice of replacing the Trustee, I shall immediately appoint the then other trustee designated by WFOE to exercise the entrusted rights under this Power of Attorney, and the new authorization shall, once made, supersede the original authorization without the requirement of my consent. In addition, I will not revoke the entrustment and authorization made to the Trustee.

If I become a person without capacity for civil conduct or with limited capacity for civil conduct, any my successors, guardians or administrators shall continue to comply with the stipulation of this Power of Attorney upon inheriting or managing the shareholders’ rights entitled to me as a shareholder of the Company.

I accept and bear the corresponding responsibilities for any legal consequences arising from the exercise of the aforesaid entrusted rights by the Trustee. I hereby confirm that in no event shall the Trustee be liable for or make any financial compensation whatsoever in respect of the exercise of the aforesaid entrusted rights. And I agree to indemnify WFOE, and hold it harmless, for all the loss suffered or likely to be suffered as a result of the exercise of the entrusted rights by the designated Trustee, including but not limited to litigation, recovery, arbitration, claim by any third party or any loss caused by administrative investigation or punishment of the government authorities.

I will provide full assistance to the Trustee in exercising the aforesaid entrusted rights and will procure the Company to provide full assistance, including signing in time the legal documents of shareholders’ meetings or other relevant legal documents made by the Trustee if necessary (such as meeting the requirements of the government departments for examination, approval, registration and filing of the required submitted documents), as well as entitling the Trustee the rights to know about the operations, business, customers, finance, employees and other relevant information of the Company, and accessing to related information of the Company.

In case the authorization or exercise of the aforesaid entrusted rights could not be realized for any reasons (except my violation of the terms of this Power of Attorney) at any time during the validity period of this trust, all parties shall immediately seek alternatives that are the closest to the unrealized ones, and sign supplemental agreements to amend or adjust the terms of this Power of Attorney to ensure the continuous realization of the purposes of this Power of Attorney if necessary.

This Power of Attorney will be effective from the date of signature and shall, once signed, supersede any undertakings, memorandums, agreements or any other documents previously made in connection with matters of this Power of Attorney, and shall be continuously effective during the period when I hold the equity of the Company.
