Dear Sir or Madam

Charming Medical Limited (the Company)

We are lawyers qualified to practise in the British Virgin Islands and have acted as British Virgin Islands advisers to the Company in connection with the Company’s registration statement on Form F-1 (the Registration Statement), including all amendments or supplements thereto, and accompanying prospectus filed with the Securities and Exchange Commission (the Commission) under the United States Securities Act of 1933, as amended (the Securities Act), relating to the offering by the Company of (a) up to 1,600,000 class A ordinary shares of par value US$0.0001 per share and (b) an option to issue up to 240,000 class A ordinary shares of par value US$0.0001 per share to cover the over-allotment option to be granted to the underwriter (collectively, the IPO Shares).

We are furnishing this opinion as Exhibits 5.1, 8.1 and 23.2 to the Registration Statement.

For the purposes of giving this opinion, we have examined the Documents (as defined in Schedule 1) which we regard as necessary in order to issue this opinion. We have not examined any other documents, official or corporate records or external or internal registers and have not undertaken or been instructed to undertake any further enquiry or due diligence in relation to the transaction which is the subject of this opinion.

In giving this opinion we have relied upon the assumptions set out in Schedule 2 which we have not verified.

Based solely upon the foregoing examinations and assumptions and having regard to legal considerations which we deem relevant, and subject to the qualifications set out in Schedule 3, we are of the opinion that under the laws of the British Virgin Islands:

The British Virgin Islands is Harneys Hong Kong office’s main jurisdiction of practice.
Jersey legal services are provided through a referral arrangement with Harneys (Jersey) which is an
independently owned and controlled Jersey law firm.

1 Existence and Good Standing. The Company is a BVI business company duly incorporated with limited liability, and is validly existing and in good standing under the laws of the British Virgin Islands. The Company is a separate legal entity and is subject to suit in its own name.

2 Maximum Number of Authorised Shares. Based on our review of the M&A (as defined in Schedule 1), the Company is authorised to issue up to a maximum of 75,000,000 ordinary shares with a par value of US$0.0001, comprising (i) 60,000,000 class A ordinary shares of par value of US$0.0001 each and (ii) 15,000,000 class B ordinary shares of par value of US$0.0001 each.

3 Valid Issuance of IPO Shares. The allotment and issuance of the IPO Shares as contemplated by the Registration Statement have been duly authorised and, when allotted, issued and fully paid for in accordance with the Registration Statement, and when the names of the shareholders are entered in the register of members of the Company, the IPO Shares will be validly allotted, issued, fully paid and non-assessable.

4 British Virgin Islands Law. The statements under the headings “Risk Factors”, “Taxation”, “Enforceability of Civil Liabilities” and “Description of Shares” in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of British Virgin Islands law, are accurate in all material respects as at the date of this opinion and such statements constitute our opinion.

This opinion is confined to the matters expressly opined on herein and given on the basis of the laws of the British Virgin Islands as they are in force and applied by the British Virgin Islands courts at the date of this opinion. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction. Except as specifically stated herein, we express no opinion as to matters of fact. Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in the Registration Statement. We express no opinion with respect to the commercial terms of the transactions the subject of this opinion.

In connection with the above opinion, we hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference made to this firm in the Registration Statement under the headings “Risk Factors”, “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.

This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein.

This opinion shall be construed in accordance with the laws of the British Virgin Islands.

Yours faithfully
