Ladies and Gentlemen:

We have acted as counsel to Datasea Inc., a Nevada corporation (the “Company”), in connection with the Underwriting Agreement dated September 11, 2023 (the “Underwriting Agreement”) by and between the Company and EF Hutton, division of Benchmark Investments, LLC, as underwriter (the “Underwriter”), relating to the sale by the Company of 5,000,000 shares of the Company’s common stock (the “Shares”) and up to an additional 750,000 Shares issuable upon exercise of an over-allotment option pursuant to the Underwriting Agreement.

This opinion is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”).

2. The Amended and Restated Bylaws of the Company;

3. The Underwriting Agreement;

The opinion expressed below is limited to the federal securities laws of the United States of America and the Nevada Revised Statutes and we express no opinion as to the effect on the matters covered by the laws of any other jurisdiction.

Based upon and subject to the foregoing, we are of the opinion that when the Shares have been delivered to and paid for by the Underwriters as contemplated by the Underwriting Agreement, the Shares will be duly authorized, validly issued, fully paid and non- assessable.
