Dear Sirs or Madams:
We are lawyers qualified to practice in the People’s Republic of China (the “PRC” or “China”, which, for purposes of this legal opinion (the “Opinion”) only, does not include the Hong Kong Special Administrative Region, the Macao Special Administrative Region or Taiwan Region), and as such are qualified to issue this Opinion on the laws and regulations of the PRC effective as of the date hereof.
We have acted as PRC counsel to Lianhe Sowell International Group Ltd (the “Company”), a company incorporated under the laws of the Cayman Islands whose ordinary shares are currently listed and traded on the Nasdaq Capital Market, in connection with the Company’s proposed offering (the “Offering”) of the securities described in the Company’s registration statement on Form F-1 (Registration No. 333-298425), including all amendments or supplements thereto (the “Registration Statement”), filed by the Company with the United States Securities and Exchange Commission (the “SEC”) under the United States Securities Act of 1933, as amended (the “Securities Act”).
In rendering this Opinion, we have carried out due diligence and examined the Registration Statement and such originals or copies, certified or otherwise identified to our satisfaction, of corporate records, agreements, certificates, approvals, Governmental Authorizations (as defined below) and other documents and instruments provided to us by the Company and the PRC Subsidiaries (as defined below), as we have considered necessary or advisable for the purpose of rendering this Opinion (collectively, the “Documents”).

C. Opinions
Based on our review of the Documents, and subject to the Assumptions, the Qualifications (as defined below) and the disclosures contained in the Registration Statement, we are of the opinion that, as of the date hereof:
| (1) | Corporate Structure. Except as disclosed in the Registration Statement, the ownership structure of the PRC Subsidiaries as set forth in the Registration Statement, both currently and immediately after giving effect to the Offering, will not result in any violation of any provision of PRC Laws in any material respect. Insofar as the description of such ownership structure in the Registration Statement relates to PRC Laws, such description is true and accurate in all material respects, and nothing has come to our attention, insofar as PRC Laws are concerned, that causes us to believe that any material matter has been omitted from such description that would make it misleading in any material respect. However, there are some uncertainties regarding the interpretation and application of PRC Laws, and there can be no assurance that the PRC government or any Governmental Agency will ultimately take a view that is consistent with our opinion stated above. |
| (2) | Taxation. The statements set forth in the Registration Statement under the caption “Taxation — People’s Republic of China Taxation,” insofar as such statements describe or summarize PRC tax laws, regulations and interpretations, are true and accurate in all material respects. To the extent that such statements set forth definitive legal conclusions under PRC tax laws and regulations, subject to the qualifications set forth therein and herein, such statements constitute our opinion as to such matters. |
| (3) | CSRC Filing. The Company has previously offered and listed securities on the Nasdaq Capital Market. Based on our understanding of the Trial Measures, the Offering constitutes a subsequent securities offering by the Company in the same overseas market in which the Company has previously offered and listed securities. Accordingly, pursuant to Article 16 of the Trial Measures, the Company is required to complete the applicable filing procedures with the CSRC within three working days after completion of the Offering, and such filing shall be made by the major PRC operating entity designated as the domestic responsible entity in accordance with the Trial Measures. The filing requirement under the Trial Measures is a filing requirement and does not constitute a pre-Offering approval requirement of the CSRC under the Trial Measures. This opinion regarding the filing requirement under the Trial Measures is separate from our opinion regarding CSRC approval under the M&A Rules set forth in paragraph (5) below. |
| (4) | Cybersecurity Review. The Cybersecurity Review Measures provide, among other things, that (i) a critical information infrastructure operator that purchases network products or services which affect or may affect national security shall apply for a cybersecurity review, (ii) data processing activities conducted by an online platform operator that affect or may affect national security may be subject to a cybersecurity review, and (iii) an online platform operator possessing personal information of more than one million users that seeks a listing in a foreign country must apply for a cybersecurity review. Based on the Company’s confirmations, neither the Company nor any PRC Subsidiary is a critical information infrastructure operator, and neither the Company nor any PRC Subsidiary possesses personal information of more than one million users. Accordingly, based on our understanding of the Cybersecurity Review Measures and the facts confirmed to us by the Company, neither the Company nor any PRC Subsidiary is required to submit an application for cybersecurity review in connection with the Offering under the mandatory filing requirements described above. However, the Cybersecurity Review Measures grant the relevant PRC regulatory authorities discretion to initiate a cybersecurity review where network products or services or data processing activities are considered to affect or potentially affect national security, and there can be no assurance that such authorities will not adopt an interpretation or take a view that differs from our opinion stated above. |
| (5) | M&A Rules. Based on our understanding of the provisions under PRC Laws, except as disclosed in the Registration Statement, and assuming that no offer, issuance or sale of the securities offered in the Offering has been or will be made directly or indirectly within the PRC, prior approval from the CSRC as contemplated under the M&A Rules is not required for the Offering. However, there are substantial uncertainties regarding the interpretation and application of the M&A Rules, other PRC Laws and future PRC laws and regulations, and there can be no assurance that any Governmental Agency will not take a view that is contrary to or otherwise different from our opinion stated herein. For the avoidance of doubt, the foregoing opinion regarding CSRC approval under the M&A Rules is separate from the CSRC filing requirement under the Trial Measures described in paragraph (3) above. |
| (6) | Recognition and Enforcement of Foreign Judgments. The recognition and enforcement of foreign court judgments in the PRC are governed by the Civil Procedure Law of the People’s Republic of China (the “PRC Civil Procedure Law”) and other applicable PRC procedural rules. Under the PRC Civil Procedure Law, a PRC court may recognize and enforce a legally effective foreign court judgment pursuant to an applicable international treaty concluded or acceded to by the PRC or on the basis of reciprocity, subject to the statutory grounds for refusal under PRC Law. The existence and application of reciprocity are subject to determination by the competent PRC court on a case-by-case basis. Accordingly, it remains uncertain whether, and on what basis, a PRC court would recognize and enforce a judgment rendered by a court in the United States or the Cayman Islands against the Company or its directors and officers. |

| (8) | Unless otherwise expressly stated herein, we have not undertaken any independent investigation, search or other verification action to determine the existence or absence of any fact, and no inference as to our knowledge of the existence or absence of any fact should be drawn from our representation of the Company or the PRC Subsidiaries or from the rendering of this Opinion; |
| (9) | This Opinion is intended to be used in the context specifically referred to herein; each paragraph shall be construed as a whole and no part shall be extracted and referred to independently; and |
| (10) | This Opinion is strictly limited to the matters stated herein and no opinion is implied or may be inferred beyond the matters expressly stated herein. The opinions expressed herein are rendered only as of the date hereof, and we assume no responsibility to advise you or any other person of any facts, circumstances, events, developments or changes in PRC Laws that may hereafter be brought to our attention or occur and that may alter, affect or modify the opinions expressed herein. |
