Dear Sirs

WiMi Hologram Cloud Inc. (the Company)

We have acted as Cayman Islands counsel to the Company in connection with the Company’s registration statement on Form F-3, including all amendments and supplements thereto (the Registration Statement), initially filed on 30 December 2024 with the U.S. Securities and Exchange Commission (the Commission) under the United States Securities Act of 1933, as amended to date (the Act) relating to securities to be issued and sold by the Company from time to time, and the prospectus supplement dated 23 May 2025 (the Prospectus Supplement). The Registration Statement and the Prospectus Supplement relate to the sale of (a) up to US$40,000,000 aggregate principal amount of a series of unsecured convertible promissory notes by way of an initial tranche in the aggregate sum of US$10,000,000 due 2026 and later tranches (together, the Convertible Notes) convertible into class B ordinary shares of the Company of a par value of US$0.002 each (the Shares) in accordance with certain convertible note purchase agreements dated 20 May 2025 (together, the CNPAs) entered into between the Company and the relevant purchasers named therein (the Purchasers) and (b) the Shares underlying the Convertible Notes pursuant to certain convertible promissory notes (i) issued on 23 May 2025 (the Initial Tranche Convertible Notes Documents) and (ii) to be issued from time to time (the Future Convertible Notes Documents, together with the Initial Tranche Convertible Note Documents, the Convertible Notes Documents) by the Company in favour of the Purchasers.

We are furnishing this opinion as Exhibit 5.1 to the Company’s current report on Form 6-K which will be incorporated by reference into the Registration Statement and the Prospectus Supplement (the Form 6-K).

SCHEDULE 2

Qualifications

Good standing

1 Under the Companies Act (Revised) (Companies Act) of the Cayman Islands, annual returns in respect of the Company must be filed with the Registrar, together with payment of annual filing fees. A failure to file annual returns and pay annual filing fees may result in the Company being struck off the Register of Companies, following which its assets will vest in the Financial Secretary of the Cayman Islands and will be subject to disposition or retention for the benefit of the public of the Cayman Islands.

2 In good standing means only that as of the date of the Good Standing Certificate the Company is up-to-date with the filing of its annual returns and payment of annual fees with the Registrar. We have made no enquiries into the Company’s good standing with respect to any filings or payment of fees, or both, that it may be required to make under the laws of the Cayman Islands other than the Companies Act.

Register of members

3 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 Act 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).

Non-assessable

4 In this opinion, the phrase “non-assessable” means, with respect to the Shares, 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 circumstance in which a court may be prepared to pierce or lift the corporate veil).

5 We are not aware of any Cayman Islands authority as to when the courts would set aside the limited liability of a shareholder in a Cayman Islands company. Our opinion on the subject is based on the Companies Act and English common law authorities, the latter of which are persuasive but not binding in the courts of the Cayman Islands. Under English authorities, circumstances in which a court would attribute personal liability to a shareholder are very limited, and include: (a) such shareholder expressly assuming direct liability (such as a guarantee); (b) the company acting as the agent of such shareholder; (c) the company being incorporated by or at the behest of such shareholder for the purpose of committing or furthering such shareholder’s fraud, or for a sham transaction otherwise carried out by such shareholder. In the absence of these circumstances, we are of the opinion that a Cayman Islands’ court would have no grounds to set aside the limited liability of a shareholder.

Register of Writs

6 Our examination of the Register of Writs cannot conclusively reveal whether or not there is:

a. any current or pending litigation in the Cayman Islands against the Company; or

b. any application for the winding up or dissolution of the Company or the appointment of any liquidator, trustee in bankruptcy or restructuring officer in respect of the Company or any of its assets,

as notice of these matters might not be entered on the Register of Writs immediately or updated expeditiously or the court file associated with the matter or the matter itself may not be publicly available (for example, due to sealing orders having been made). Furthermore, we have not conducted a search of the summary court. Claims in the summary court are limited to a maximum of CI $20,000.
