Ladies and Gentlemen:

Reference is made to the Registration Statement on Form S-4 (File No. 333-268343) (the “Registration Statement”) filed with the Securities and Exchange Commission by LBBB Merger Corp., a Delaware corporation (the “Company”), under the Securities Act of 1933, as amended (the “Act”), covering an offering of (i) up to 30,436,539 shares (the “Merger Shares”) of common stock of the Company, par value of $0.0001 each (the “Common Stock”), (ii) 3,450,000 redeemable warrants (the “Warrants”), each Warrant entitling its holder to purchase one share of Common Stock, and (iii) 690,000 shares (the “Rights Shares”) of Common Stock to be issued to holders of rights issued by Lakeshore Acquisition II Corp.

We have examined such documents and considered such legal matters as we have deemed necessary and relevant as the basis for the opinion set forth below. With respect to such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as reproduced or certified copies, and the authenticity of the originals of those latter documents.
