Dear Sirs,

Re: Huitao Technology Co., Ltd. (the "Company")

We have acted as special legal Cayman Islands counsel to the Company in connection with a registration statement on Form F-3 (Registration No. 333 filed with the U.S. Securities and Exchange Commission (the "Commission") on 25 February 2020, including all amendments or supplements thereto (the "Registration Statement", which term does not include any other document or agreement whether or not specifically referred to therein or attached as an exhibit or schedule thereto) relating to the registration under the U.S. Securities Act of 1933, as amended, (the "Securities Act") and the base prospectus (the “Prospectus”) included therein, relating to the issue and sale by the Company from time to time of the ordinary shares of the Company, par value US$0.001 each (the "Ordinary Shares"), the preference shares, par value US$0.001 each (the “Preference Shares” and together with the Ordinary Shares, the "Equity Securities", which term includes any ordinary shares or preference shares to be issued pursuant to the conversion, exchange or exercise of any other Securities), senior debt securities ("Senior Debt Securities"), subordinated debt securities ("Subordinated Debt Securities" and, together with Senior Debt Securities, "Debt Securities"), warrants ("Warrants"), units (“Units”) or rights (“Rights”) consisting of any combination of the foregoing securities of the Company (collectively, the "Securities").

For the purposes of giving this opinion, we have examined and relied upon copies of the following documents:

1. the Registration Statement; and

2. Prospectus.

We have also reviewed the certificate of incorporation of the Company dated 28 June 2019, a copy of the certificate of name change of the Company dated 12 July 2019, the amended and restated memorandum of association and the articles of association of the Company filed 12 July 2019 (together, the “Constitutional Documents”), each certified by the Secretary of the Company on 13 January 2020, copies of unanimous written resolutions of its directors dated 10 January 2020 (the "Resolutions"), a certificate of good standing (the “Cogs”) of the Company issued by the Registrar of Companies of the Cayman Islands and dated 25 February 2020 (the “Certificate Date”), and such other documents and made such enquiries as to questions of law as we have deemed necessary in order to render the opinion set forth below. The Constitutional Documents, Cogs, Resolutions, Registration Statement and Prospectus are hereinafter collectively referred to as the “Corporate Documents”.

As part of the corporate actions taken and to be taken in connection with the issuance and sale of the Securities (the “corporate proceedings”), the Company has informed us that before the Securities are issued and sold under the Registration Statement, the board of directors of the Company (the “Board”) will authorise the issuance and approve the terms of any Securities to be issued and sold from time to time under the Registration Statement, and, in relation to any Preference Shares effect any necessary amendments to the amended and restated memorandum and articles of association of the Company (the “M&A”), in each case in a form acceptable to us and Cayman Islands law, and such applicable corporate proceedings (hereinafter referred to as the “Board Authorisations”) shall be in full force and effect at the time of any such issuance and sale.

The Company has informed us that the Securities will be sold or delivered on a delayed or continuous basis from time to time as set forth in the Registration Statement (and any amendments and/or supplement thereto), the Prospectus contained therein and any prospectus supplement. We understand that prior to the sale of any Securities under the Registration Statement, the Company will afford us an opportunity to review the applicable Board Authorisations and, if necessary, amendments to the M&A and operative documents pursuant to which such Securities are to be sold and will file any applicable amendment and/or supplement to the Registration Statement (which may include as an exhibit thereto an amended opinion) or prospectus supplement as we may reasonably consider necessary or appropriate by reason of the terms of the sale of such Securities.

The obligations of the Company in connection with any Security and any indenture or other agreement or document relating thereto (a) will be subject to the laws from time to time in effect relating to bankruptcy, insolvency, liquidation, possessory liens, rights of set off, reorganisation, amalgamation, merger, moratorium or any other laws or legal procedures, whether of a similar nature or otherwise, generally affecting the rights of creditors as well as applicable international sanctions, (b) will be subject to statutory limitation of the time within which proceedings may be brought, (c) will be subject to general principles of equity and, as such, specific performance and injunctive relief, being equitable remedies, may not be available, (d) may not be given effect to by a Cayman Islands court if and to the extent they constitute the payment of an amount which is in the nature of a penalty, and (e) may not be given effect by a Cayman Islands court to the extent that they are to be performed in a jurisdiction outside the Cayman Islands and such performance would be illegal under the laws of that jurisdiction. Notwithstanding any contractual submission to the jurisdiction of specific courts, a Cayman Islands court has inherent discretion to stay or allow proceedings in the Cayman Islands courts.

We express no opinion with respect to the issuance of Equity Securities pursuant to any provision of the Registration Statement or Prospectus that purports to obligate the Company to issue Shares following the commencement of a winding up or liquidation.

We have made no investigation of and express no opinion in relation to the laws of any jurisdiction other than the Cayman Islands. This opinion is to be governed by and construed in accordance with the laws of the Cayman Islands and is limited to and is given on the basis of the current law and practice in the Cayman Islands. This opinion is issued solely for the purposes of the filing of the Registration Statement and the issuance of the Securities by the Company and is not to be relied upon in respect of any other matter.

On the basis of and subject to the foregoing, we are of the opinion that:

1. As at the Certificate Date, the Company is duly incorporated and existing under the laws of the Cayman Islands in good standing.

2. Upon the due issuance of Ordinary Shares and/or Preference Shares and payment of the consideration therefor, such Ordinary Shares and/or Preference Shares will be validly issued, fully paid and non-assessable (which term means when used herein that no further sums are required to be paid by the holders thereof in connection with the issue of such shares).

3. Upon the due issuance of: (a) Senior Debt Securities of any series; (b) Subordinated Debt Securities of any series; (c) Warrants; (d) Units and/or Rights, and payment of the consideration therefor, such Securities will be validly issued and (except in the case of any Equity Securities forming part of a Unit) will constitute valid and binding obligations of the Company in accordance with the terms thereof.

4. When a Warrant Agreement as contemplated by the Registration Statement (including any amendments and/or supplement thereto) and any prospectus supplements relating thereto, and by the applicable Board Authorisations or other corporate proceedings, has been duly authorised, executed and delivered by the Company, and assuming due execution and delivery by the warrant agent, such Warrant Agreement will constitute a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms.
