Dear Sirs

Tuniu Corporation

We have acted as Cayman Islands legal advisers to Tuniu Corporation (the “Company”) in connection with the Company’s registration statement on Form F-1, including all amendments or supplements thereto, filed with the United States Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933 (the “Act”), as amended, (the “Registration Statement”), related to the offering by the Company and the sale by the selling shareholders (the “Selling Shareholders”) of American Depositary Shares representing certain Class A ordinary shares, par value US$0.0001 per share (the “Shares”). This opinion is given in accordance with the terms of the Legal Matters section of the Registration Statement.

1 Documents Reviewed

For the purposes of this opinion we have reviewed originals, copies, drafts or conformed copies of the documents listed in Schedule 1 to this opinion, being all of the documents necessary to form our opinion. Defined terms shall have the meanings set out in Schedule 1 or in the Registration Statement.

2 Assumptions

The following opinions are given only as to and based on circumstances and matters of fact existing at the date hereof and as to the laws of the Cayman Islands as the same are in force at the date hereof. In giving this opinion, we have relied upon the completeness and accuracy (and assumed the continuing completeness and accuracy as at the date hereof) of the Director’s Certificate, as to matters of fact, without further verification and have assumed that copy documents or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals.

3 Opinions

Based upon, and subject to, the foregoing assumptions, and having regard to such legal considerations as we deem relevant, we are of the opinion that:

3.1 the Company has been duly incorporated and is validly existing and in good standing under the laws of the Cayman Islands;

3.2 the Shares to be offered and issued by the Company as contemplated by the Registration Statement have been duly authorised for issue, and when issued by the Company against payment in full of the consideration, in accordance with the terms set out in the Registration Statement and duly registered in the Company’s Register of Members (shareholders), such Shares will be validly issued, fully paid and non-assessable;

3.3 shares to be sold by the Selling Shareholders have been legally and validly issued as fully paid and non-assessable; and

3.4 the statements under the caption “Taxation” in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of Cayman Islands law, are accurate in all material respects and such statements constitute our opinion.

We hereby consent to the prospectus discussion of this opinion, to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the headings “Enforceability of Civil Liabilities” and “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In providing our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the Rules and Regulations of the Commission thereunder.

This opinion is limited to the matters detailed herein and is not to be read as an opinion with respect to any other matter.

Yours faithfully

Dear Sirs

Tuniu Corporation (the “Company”)

I, Dunde Yu, being a director of the Company, am aware that you are being asked to provide a legal opinion (the “Opinion”) in relation to certain aspects of Cayman Islands law. Capitalised terms used in this certificate have the meaning given to them in the Opinion. I hereby certify that:

1 The Pre-IPO M&A remain in full force and effect and are unamended save that the Company has conditionally adopted the IPO M&A by a special resolution passed on April 4, 2014 to take effect immediately upon completion of the Company’s IPO.

2 The Resolutions were signed by all the directors or all the shareholders, as the case may be, in the manner prescribed in the Pre-IPO M&A.

3 The shareholders of the Company have not restricted or limited the powers of the directors in any way. There is no contractual or other prohibition (other than as arising under Cayman Islands law) binding on the Company prohibiting it from performing its obligations under the corporate governance practices described or provided for (as the case may be) in the exhibits to the IPO Board Resolutions.

4 The Resolutions were duly adopted, are in full force and effect at the date hereof and have not been amended, varied or revoked in any respect.

5 The directors of the Company at the date of the IPO Board Resolutions and at the date hereof were and are as follows:

Dunde Yu

Haifeng Yan

Thomas Gai Tei Tsao

Frank Lin

Steve Yue Ji

Eugene Chehchun Huang

6 The minute book and corporate records of the Company as maintained at its registered office in the Cayman Islands and made available to you are complete and accurate in all material respects, and all minutes and resolutions filed therein represent a complete and accurate record of all meetings of the shareholders and directors (or any committee thereof) (duly convened in accordance with the then current articles of association of the Company) and all resolutions passed at the meetings, or passed by written consent as the case may be.

7 Each director considers the transactions contemplated by the Registration Statement to be of commercial benefit to the Company and has acted bona fide in the best interests of the Company, and for a proper purpose of the Company, in relation to the transactions which are the subject of the Opinion.

8 To the best of my knowledge and belief, having made due inquiry, the Company is not the subject of legal, arbitral, administrative or other proceedings in any jurisdiction. Nor have the directors or shareholders taken any steps to have the Company struck off or placed in liquidation, nor have any steps been taken to wind up the Company. Nor has any receiver been appointed over any of the Company’s property or assets.

9 The Company is not a central bank, monetary authority or other sovereign entity of any state.

I confirm that you may continue to rely on this Certificate as being true and correct on the day that you issue the Opinion unless I shall have previously notified you personally (Attn: Mr Richard Thorp) to the contrary.
