Introductory Note

This Amendment No.1 to Schedule 13D (the
“Amendment No. 1”) amends and supplements the Schedule 13D filed by the Reporting Persons with the SEC on February
5, 2016 (the “Original Schedule 13D”). Except as amended and supplemented herein, the information set forth in the
Original Schedule 13D remains unchanged. Capitalized terms used herein have meanings as assigned thereto in the Original Schedule
13D unless defined herein.

Item 4. Purpose of Transaction.

Item 4 of the Original Schedule 13D is hereby
amended and restated in its entirety as follows:

On February 5, 2016, IDG Growth II and IDG
Investors II entered into a consortium agreement (the “Consortium Agreement”) with Leilei Wang, the chairman and chief
executive officer of the Issuer, Right Advance Management Ltd and Chiming Bells International Limited (collectively, the “Chairman
Parties”, and together with IDG Growth II and IDG Investors II, the “Consortium”), pursuant to which the Consortium
will cooperate in good faith in connection with an acquisition transaction (the “Transaction”) with respect to the
Issuer. The Consortium Agreement provides, among other things, for: cooperation in arranging financing; engaging advisors; admission
of new Consortium members; cooperation in obtaining applicable governmental, statutory, regulatory or other approvals, licenses,
waivers or exemptions for the consummation of the transactions; and cooperation in preparing definitive documentation with respect
to the Transaction. During the period beginning on the date of the Consortium Agreement and ending on the earlier of (i) the 12-month
anniversary of the date of the Consortium Agreement and (ii) the termination of the Consortium Agreement on the occurrence of other
termination events, members of the Consortium have agreed to work exclusively with each other with respect to the Transaction and
not to (a) make a competing proposal for the acquisition of control of the Issuer or (b) acquire or dispose of any securities
of the Issuer.

On February 17, 2016, 上海宏流资产管理中心(有限合伙)(Shanghai
Trend Asset Management Center (Limited Partnership)) (“Shanghai Trend”), a PRC limited partnership, signed an adherence
agreement to the Consortium Agreement (the “Shanghai Trend Adherence Agreement”), pursuant to which Shanghai Trend
joined the Consortium. References to the “Consortium” or “Consortium Members” after February 17, 2016
shall include Shanghai Trend.

IDG Growth II and Leilei Wang have previously
submitted a preliminary non-binding proposal (the “Proposal”) to the Issuer’s board of directors in connection
with the Transaction. Under the Proposal, members of the Consortium proposed to acquire, through an acquisition vehicle to be formed
by them, all of the outstanding ordinary shares of the Company and ADSs not owned by them for US$8.56 per ADS or US$0.2140 per
ordinary share in cash, representing a premium of 21.8% to the closing price of the Issuer’s ADSs on June 26, 2015 and a
premium of approximately 20% to the average closing price of the Issuer’s ADSs during the last 30 trading days. The Proposal
also provides that, among other things, the Consortium will negotiate and execute definitive agreements with respect to the Transaction
that will include provisions typical for transactions of this type.

If the Transaction is completed, the Issuer’s
ADSs would be delisted from the NASDAQ Global Select Market, and the Issuer’s obligation to file periodic reports under the
Act would terminate. In addition, consummation of the Transaction could result in one or more of the actions specified in clauses
(a)-(j) of Item 4 of Schedule 13D, including the acquisition or disposition of securities of the Issuer, a merger or other extraordinary
transaction involving the Issuer, a change to the board of directors of the Issuer (as the surviving company in the merger), and
a change in the Issuer’s memorandum and articles of association to reflect that the Issuer would become a privately held
company.

Other than as described above, none of
the Reporting Persons currently has any plans or proposals that relate to, or would result in, any of the matters listed in Items
4(a)–(j) of Schedule 13D, although the Reporting Persons may, at any time and from time to time, review or reconsider their
position and/or change their purpose and/or formulate plans or proposals with respect thereto. As a result of these activities,
one or more of the Reporting Persons may suggest or take a position with respect to potential changes in the operations, management,
or capital structure of the Issuer as a means of enhancing shareholder value. Such suggestions or positions may include one or
more plans or proposals that relate to or would result in any of the actions required to be reported herein, including, without
limitation, such matters as acquiring additional securities of the Issuer or disposing of securities of the Issuer; entering into
an extraordinary corporate transaction such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;
selling or transferring a material amount of assets of the Issuer or any of its subsidiaries; changing the present board of directors
or management of the Issuer, including changing the number or term of directors or filling any existing vacancies on the board
of directors; materially changing the present capitalization or dividend policy of the Issuer; materially changing the Issuer’s
business or corporate structure; changing the Issuer’s certificate of incorporation, bylaws or instruments corresponding
thereto or taking other actions which may impede the acquisition of control of the Issuer by any person; causing a class of securities
of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer
quotation system of a registered national securities association; causing a class of equity securities of the Issuer to become
eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Act; and taking any action similar to
any of those enumerated above.

References to the Consortium Agreement and
the Shanghai Trend Adherence Agreement in this statement are qualified in their entirety by reference to the Consortium Agreement
and the Shanghai Trend Adherence Agreement, copies of which are attached hereto as Exhibits 2 and 3 and incorporated herein by
reference in their entirety.

Item 6. Contracts, Arrangements, Understandings or Relationships
with respect to Securities of the Issuer.

Item 6 of the Original Schedule 13D is
hereby amended and restated in its entirety as follows:

The Consortium Agreement and the Shanghai
Trend Adherence Agreement, which have been filed as Exhibit 2 and Exhibit 3 to this statement, are incorporated herein by reference
in their entirety. In addition, the information set forth in Items 3, 4 and 5 of this statement is incorporated by reference in
its entirety into this Item 6. To the best knowledge of the Reporting Persons, except as provided herein, there are no other contracts,
arrangements, understandings or relationships (legal or otherwise) among the Reporting Persons and between any of the Reporting
Persons and any other person with respect to any securities of the Issuer, joint ventures, loan or option arrangements, puts or
calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, or a pledge or contingency,
the occurrence of which would give another person voting power over the securities of the Issuer.
