Re: Big Tree Cloud Holdings Limited Registration Statement on Form F-4

Ladies and Gentlemen:

We have acted as counsel to Big Tree Cloud Holdings Limited, a Cayman Islands exempted company (the “Company”), in connection with the preparation and filing with the U.S. Securities and Exchange Commission (the “Commission”), pursuant to the Securities Act of 1933, as amended (the “Securities Act”), of the Registration Statement on Form F-4 of the Company (as amended or supplemented through the date hereof, the “Registration Statement”), containing a proxy statement/prospectus relating to, among other things, the approval of the Business Combination (as defined below).

On October 9, 2023, the Company entered into that certain Agreement and Plan of Merger (as may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among Big Tree Cloud International Group Limited, an exempted company incorporated in the Cayman Islands (“Holdco”), Plutonian Acquisition Corp., a Delaware corporation (“Plutonian”), Big Tree Cloud Merger Sub I Limited, an exempted company incorporated in Cayman Islands and a direct wholly-owned subsidiary of the Company (“Merger Sub 1”), Big Tree Cloud Merger Sub II Inc., a Delaware corporation and a direct wholly-owned subsidiary of the Company (“Merger Sub 2”), and Guangdong Dashuyun Investment Holding Group Co., Ltd., a limited liability company incorporated in the PRC, pursuant to which (1) Merger Sub 1 will merge with and into Holdco (the “Initial Merger”), and Holdco will be the surviving corporation of the Initial Merger and a direct wholly-owned subsidiary of the Company, and (2) following confirmation of the effectiveness of the Initial Merger, Merger Sub 2 will merge with and into Plutonian (the “SPAC Merger” and together with the Initial Merger, the “Mergers”), and Plutonian will be the surviving corporation of the SPAC Merger and a direct wholly owned subsidiary of the Company. The Mergers and the other transactions to be consummated pursuant to the Merger Agreement are collectively referred to as the “Business Combination.”

In connection with the Business Combination, (i) each unit of Plutonian (“Plutonian Unit”), consisting of one share of the Plutonian’ s common stock (“Plutonian Common Stock”), par value $0.0001 per share, one warrant (“Plutonian Warrant”) to purchase one Plutonian Common Stock at an exercise price of $11.50 per share on the terms and conditions set forth in the warrant agreement (the “Warrant Agreement”), dated November 9, 2022, between Plutonian and Continental Stock Transfer & Trust Company (“Continental”), as warrant agent, and one right of Plutonian (“Plutonian Right”) convertible into one-sixth (1/6) of a share of Plutonian Common Stock at the closing of the Business Combination, that is outstanding immediately prior to the effectiveness of the SPAC Merger, shall be automatically detached and the holder thereof shall be deemed to hold one share of Plutonian Common Stock, one Plutonian Warrant, and one Plutonian Right in accordance with the terms of the applicable Plutonian Unit; (ii) each share of Plutonian Common Stock that is issued and outstanding immediately prior to the effectiveness of the SPAC Merger (including each share of Plutonian Common Stock converted from Plutonian Rights) will automatically be cancelled and cease to exist in exchange for the right to receive one newly issued, fully paid and non-assessable ordinary share of the Company, par value $0.0001 per share (“Company Ordinary Shares”); (iii) each Plutonian Warrant that is issued and outstanding immediately prior to the effectiveness of the SPAC Merger will automatically be cancelled and cease to exist in exchange for the right to receive one warrant to purchase one Company Ordinary Share at an exercise price of $11.50 per share ( “Company Warrants”); (iv) each Plutonian Right that was issued and outstanding immediately prior to the effectiveness of the SPAC Merger will be cancelled and cease to exist in exchange for the right to receive one-sixth (1/6) share of Plutonian Common Stock; and (v) each ordinary share of Holdco, par value $1.00 per share, that is issued and outstanding immediately prior to the effectiveness of the Initial Merger will automatically be cancelled and cease to exist in exchange for the right to receive such number of Company Ordinary Shares.
