Ucommune International Ltd

We have acted as Cayman Islands legal advisers to Ucommune International Ltd (the “Company”) in connection with the Company’s registration statement on Form F-1, including all amendments or supplements thereto (the “Registration Statement”), filed with the Securities and Exchange Commission under the U.S. Securities Act of 1933, as amended, to date relating to the offering by the Company of certain Class A ordinary shares of par value US$0.0001 each (the “Shares”) and warrants to purchase certain Shares (the “Warrants”), such Warrants to be issued under a warrant agent agreement (the “Warrant Agreement”) to be entered into between the Company with American Stock Transfer & Trust Company, LLC as warrant agent for such Warrants..

We are furnishing this opinion as Exhibits 5.1, 8.1 and 23.4 to the Registration Statement.

1 Documents Reviewed

For the purposes of this opinion letter, we have reviewed only originals, copies or final drafts of the following documents and such other documents as we have deemed necessary in order to render the opinions below:

1.1 The certificate of incorporation of the Company dated 16 June 2020 issued by the Registrar of Companies in the Cayman Islands.

1.2 The amended and restated memorandum and articles of association of the Company as conditionally adopted by a special resolution passed on 17 November 2020 and effective upon the effective date of the merger between the Company and Orisun Acquisition Corp. (the “Memorandum and Articles”).

1.6 The Registration Statement.

2 Assumptions

The following opinions are given only as to, and based on, circumstances and matters of fact existing and known to us on the date of this opinion letter. These opinions only relate to the laws of the Cayman Islands which are in force on the date of this opinion letter. In giving these opinions we have relied (without further verification) upon the completeness and accuracy, as of the date of this opinion letter, of the Director’s Certificate and the Certificate of Good Standing. We have also relied upon the following assumptions, which we have not independently verified:

2.1 Copies of documents, conformed copies or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals.

2.2 All signatures, initials and seals are genuine.

2.3 The Warrants and the Warrant Agreement have been or will be authorised and duly executed and unconditionally delivered by or on behalf of all relevant parties in accordance with all relevant laws (other than, with respect to the Company, the laws of the Cayman Islands).

2.4 The Warrants and the Warrant Agreement are, or will be, legal, valid, binding and enforceable against all relevant parties in accordance with their terms under the laws of the State of New York and all other relevant laws (other than, with respect to the Company, the laws of the Cayman Islands).

2.5 The choice of the laws of the State of New York as the governing law of the Warrants and the Warrant Agreement has been made in good faith and would be regarded as a valid and binding selection which will be upheld by courts located within the Borough of Manhattan in the City and State of New York and any other relevant jurisdiction (other than the Cayman Islands) as a matter of the laws of the State of New York and all other relevant laws (other than the laws of the Cayman Islands).

2.6 The Company will have sufficient authorised but unissued Shares in its authorised share capital to enable the Company to issue the Shares upon exercise of the Warrants.

2.7 The capacity, power, authority and legal right of all parties under all relevant laws and regulations (other than, with respect to the Company, the laws and regulations of the Cayman Islands) to enter into, execute, unconditionally deliver and perform their respective obligations under the Warrants and the Warrant Agreement.

2.8 The Warrants will be issued, authenticated and certificated as required in accordance with the provisions of the Warrant Agreement, and certificates representing the Warrants will have been duly executed, countersigned, registered and delivered in accordance with the provisions of the Warrant Agreement.

2.9 There is no contractual or other prohibition or restriction (other than as arising under Cayman Islands law) binding on the Company prohibiting or restricting it from entering into and performing its obligations under the Warrants and the Warrant Agreement.

2.10 No monies paid to or for the account of any party under the Warrants or the Warrant Agreement or any property received or disposed of by any party to the Warrants and the Warrant Agreement in each case in connection with the Warrants and the Warrant Agreement or the consummation of the transactions contemplated thereby represent or will represent proceeds of criminal conduct or criminal property or terrorist property (as defined in the Proceeds of Crime Act (2020 Revision) and the Terrorism Act (2018 Revision), respectively).

2

2.11 There is nothing under any law (other than the law of the Cayman Islands), which would or might affect the opinions set out below. Specifically, we have made no independent investigation of the laws of the State of New York.

2.12 The Company will receive money or money’s worth in consideration for the issue of the Shares and none of the Shares were or will be issued for less than par value.

3 Opinion

Based upon the foregoing and subject to the qualifications set out below 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 as an exempted company with limited liability and is validly existing and in good standing with the Registrar of Companies under the laws of the Cayman Islands.

3.2 The authorised share capital of the Company is US$50,000 divided into 500,000,000 ordinary shares of par value of US$0.0001 each, comprising (a) 400,000,000 Class A Ordinary Shares of par value of US$0.0001 each and (b) 100,000,000 Class B Ordinary Shares of par value of US$0.0001 each.

3.3 The issue and allotment of the Shares (including the Shares issuable upon the exercise of the Warrants) have been duly authorised and when allotted, issued and paid for as contemplated in the Registration Statement, the Shares will be legally issued and allotted, fully paid and non-assessable. As a matter of Cayman Islands law, a share is only issued when it has been entered in the register of members (shareholders).

3.4 The execution, issue, delivery and performance of the Warrants have been authorised by and on behalf of the Company and, upon the execution and unconditional delivery of the Warrants by any director of the Company for and on behalf of the Company, the Warrants will have been duly executed, issued and delivered on behalf of the Company and will constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms.

3.5 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 that such statements constitute our opinion.

4 Qualifications

The opinions expressed above are subject to the following qualifications:

4.1 The obligations assumed by the Company under the Warrants and the Warrant Agreement will not necessarily be enforceable in all circumstances in accordance with their terms. In particular:

(a) enforcement may be limited by bankruptcy, insolvency, liquidation, reorganisation, readjustment of debts or moratorium or other laws of general application relating to, protecting or affecting the rights of creditors;

3

(b) enforcement may be limited by general principles of equity. For example, equitable remedies such as specific performance may not be available, inter alia, where damages are considered to be an adequate remedy;

(c) some claims may become barred under relevant statutes of limitation or may be or become subject to defences of set off, counterclaim, estoppel and similar defences;

(d) where obligations are to be performed in a jurisdiction outside the Cayman Islands, they may not be enforceable in the Cayman Islands to the extent that performance would be illegal under the laws of that jurisdiction;

(e) the courts of the Cayman Islands have jurisdiction to give judgment in the currency of the relevant obligation and statutory rates of interest payable upon judgments will vary according to the currency of the judgment. If the Company becomes insolvent and is made subject to a liquidation proceeding, the courts of the Cayman Islands will require all debts to be proved in a common currency, which is likely to be the “functional currency” of the Company determined in accordance with applicable accounting principles. Currency indemnity provisions have not been tested, so far as we are aware, in the courts of the Cayman Islands;

(f) arrangements that constitute penalties will not be enforceable;

(g) enforcement may be prevented by reason of fraud, coercion, duress, undue influence, misrepresentation, public policy or mistake or limited by the doctrine of frustration of contracts;

(h) provisions imposing confidentiality obligations may be overridden by compulsion of applicable law or the requirements of legal and/or regulatory process;

(i) the courts of the Cayman Islands may decline to exercise jurisdiction in relation to substantive proceedings brought under or in relation to the Warrants and the Warrant Agreement in matters where they determine that such proceedings may be tried in a more appropriate forum;

(j) we reserve our opinion as to the enforceability of the relevant provisions of the Warrants and the Warrant Agreement to the extent that they purport to grant exclusive jurisdiction as there may be circumstances in which the courts of the Cayman Islands would accept jurisdiction notwithstanding such provisions;

(k) a company cannot, by agreement or in its articles of association, restrict the exercise of a statutory power and there is doubt as to the enforceability of any provision in the Warrants and the Warrant Agreement whereby the Company covenants to restrict the exercise of powers specifically given to it under the Companies Act (2021 Revision) (the “Companies Act”), including, without limitation, the power to increase its authorised share capital, amend its memorandum and articles of association or present a petition to a Cayman Islands court for an order to wind up the Company; and

(l) if the Company becomes subject to Part XVIIA of the Companies Act, enforcement or performance of any provision in the Warrants and the Warrant Agreement which relates, directly or indirectly, to an interest in the Company constituting shares, voting rights or director appointment rights in the Company may be prohibited or restricted if any such relevant interest is or becomes subject to a restrictions notice issued under the Companies Act.

4

4.2 Applicable court fees will be payable in respect of the enforcement of the Warrants and the Warrant Agreement.

4.3 To maintain the Company in good standing with the Registrar of Companies under the laws of the Cayman Islands, annual filing fees must be paid and returns made to the Registrar of Companies within the time frame prescribed by law.

4.4 Under the Companies Act, the register of members of a Cayman Islands company is by statute regarded as prima facie evidence of any matters which the Companies Law directs or authorises to be inserted therein. A third party interest in the shares in question would not appear. An entry in the register of members may yield to a court order for rectification (for example, in the event of fraud or manifest error).

4.5 In this opinion letter the phrase “non-assessable” means, with respect to shares in the Company, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the shares by the Company or its creditors (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

4.6 The obligations of the Company may be subject to restrictions pursuant to United Nations and United Kingdom sanctions extended to the Cayman Islands by Orders of Her Majesty in Council and sanctions imposed by Cayman Islands authorities, under Cayman Islands legislation.

4.7 We express no opinion as to the meaning, validity or effect of any references to foreign (i.e. non-Cayman Islands) statutes, rules, regulations, codes, judicial authority or any other promulgations and any references to them in the Warrants and the Warrant Agreement.

Except as specifically stated herein, we express no view as to the commercial terms of the Warrants or the Warrant Agreement or whether such terms represent the intentions of the parties, and we make no comment with regard to warranties or representations that may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions, which are the subject of this opinion.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our name under the headings “Enforceability of Civil Liabilities”, “Taxation” and “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the Rules and Regulations of the Commission thereunder.

Yours faithfully
