Re: American Depositary Receipts for Class A Ordinary Shares, Par Value $0.00005 per share, of Baidu.com, Inc.

Ladies and Gentlemen:

We refer to the registration statement to be filed on Form F-6 under the Securities Act of 1933 (the "Registration Statement") by the legal entity created by the agreement (the "Deposit Agreement") for issuance of American Depositary Shares ("ADSs") evidenced by American Depositary Receipts ("ADRs") for Class A Ordinary Shares, par value $0.00005 per share, of Baidu.com, Inc. for which you propose to act as Depositary.

We are of the opinion that the ADSs covered by the Registration Statement, when issued in accordance with the terms of the Deposit Agreement, will, when sold, be legally issued and will entitle the holders thereof to the rights specified in the Deposit Agreement and the ADRs.

This opinion may be used by you as an exhibit to the Registration Statement.

Very truly yours,
