   1.                                                   We note your disclosure 
that "PubCo, with Tycoon being its wholly-owned subsidiary

of China, or Mainland China." Please revise your disclosure to
                                                        clearly state that you 
are not a Chinese operating company, but a Cayman Islands holding
                                                        company with operations 
conducted by your subsidiary. As a related matter, we note your
                                                        disclosure that 
"investments in PubCo   s Ordinary Shares are not purchases of equity

         interests in the Chinese operating company. Please also revise the 
disclosure on your
         cover page to clearly disclose how you will refer to the holding 
company and its
         subsidiary when providing the disclosure throughout the document so 
that it is clear to
         investors which entity the disclosure is referencing and which 
subsidiaries or entities are
         conducting the business operations.
2.       We note your response to comment 3 and your revised disclosure that 
"because our
         business is subject to the laws and regulations of the PRC, there are 
additional legal and
         operational risks associated with being based in China," with a cross 
reference to your risk
         factor disclosure. Please further revise your disclosure as follows:

                Please revise your disclosure to clearly state that the legal 
and operational risks
              associated with being based in China could result in a material 
change in your
              operations.

                Where you disclose that there may be an impact on the value of 
your
              securities, disclose that the value of your securities could 
significantly decline and
              that the value of such securities could become worthless.

                We note your disclosure that "expanding the categories of 
industries and companies
              whose foreign securities offerings are subject to government 
review could
              significantly limit or hinder PubCo   s ability to offer or 
continue to offer securities to
              investors." Please revise the disclosure on your cover page to 
more broadly state
              that the legal and operational risks associated with being based 
in or having the
              majority of the company   s operations in China could result in a 
material change in
              your operations and/or the value of the securities you are 
registering for sale or could
              significantly limit or completely hinder your ability to offer or 
continue to offer
              securities to investors and cause the value of such securities to 
significantly decline or
              be worthless.

         For additional guidance, please see the Division of Corporation 
Finance's Sample Letter to
         China-Based Companies issued by the Staff in December 2021.
3.     As a related matter, we note your revised disclosure that "the approval 
of the China
       Securities Regulatory Commission (the "CSRC"), the Cyberspace 
Administration of
       China (the    CAC   ), or other PRC regulatory agencies will be required 
in connection with
       the Business Combination." However, we also note your disclosure that 
"[e]xcept for the
       Trial Measures, no other relevant laws or regulations in the PRC 
explicitly require Baird
       Medical to seek approval from the Cyberspace Administration of China 
("CAC") or any
       other PRC governmental authorities for its overseas listing plan."

Risk Factor Summary, page 14

4.       For each risk factor in your summary, please provide a cross reference 
to the more
         detailed discussion of each of this risks elsewhere in the prospectus. 
Revise your risk
         factor summary to describe the significant regulatory, liquidity, and 
enforcement risks.
         For example, in your risk factor summary, specifically discuss risks 
arising from the legal
         system in China, including risks and uncertainties regarding the 
enforcement of laws and
         that rules and regulations in China can change quickly with little 
advance notice; and the
         risk that the Chinese government may intervene or influence your 
operations at any time,
         or may exert more control over offerings conducted overseas and/or 
foreign investment in
         China-based issuers, which could result in a material change in your 
operations and/or the
         value of the securities you are registering for sale. Acknowledge any 
risks that any actions
         by the Chinese government to exert more oversight and control over 
offerings that are
         conducted overseas and/or foreign investment in China-based issuers 
could significantly
         limit or completely hinder your ability to offer or continue to offer 
securities to investors
         and cause the value of such securities to significantly decline or be 
worthless.
Questions and Answers for Stockholders of ExcelFin, page 17

5.       We acknowledge your response to prior comment 5, including that The 
ExcelFin private
         placement warrants will be terminated upon the closing of the Business 
Combination.
         Given that the private placement warrants will not be cancelled until 
closing of the
         business combination, please expand your disclosure to address the 
material risks, if any,
         to public warrant holders arising from the differences between private 
and public
         warrants. As a related matter, we note your disclosure on page 134 
that the Sponsor paid
         an aggregate of $11,700,000 for the private placement warrants, has 
agreed to surrender
         the private placement warrants for no additional consideration, will 
be issued PubCo
         ordinary shares in exchange for its Class A common stock, and "[i]f 
the Business
         Combination does not close, the private placement warrants will expire 
worthless and the
         Sponsor will have no means to recover its $11,700,000 investment in 
ExcelFin." Please
         clarify how the Sponsor will recover its $11,700,000 investment in the 
private placement
         warrants if it has agreed to surrender the warrants for no 
consideration, including if the
         Sponsor will receive shares in PubCo in exchange for shares underlying 
the private
         placement warrants.
Q: What equity stake will current stockholders of ExelFin and Baird Medical 
hold in PubCo after
the Closing?, page 21

6.       We note your revised disclosure in response to comment 7, including an 
interim scenario
         of 17.7% redemptions. Please clarify what percentage of public 
shareholders redeem their
         shares in your maximum redemption scenario. Please also revise to 
clarify whether it is
         possible that more public shareholders may redeem than assumed for the 
purposes of your
         maximum redemption scenario.

Summary of the Proxy Statement/Prospectus, page 36

7.       Revise your summary of the proxy statement/prospectus to disclose, as 
you do elsewhere
         in your filing, each permission or approval that you or your 
subsidiaries are required to
         obtain from Chinese authorities to operate your business and to offer 
the securities being
         registered to foreign investors. State whether you or your 
subsidiaries are covered by
         permissions requirements from the China Securities Regulatory 
Commission (CSRC),
         Cyberspace Administration of China (CAC) or any other governmental 
agency that is
         required to approve your subsidiaries operations, and state 
affirmatively whether you have
         received all requisite permissions or approvals and whether any 
permissions or approvals
         have been denied. Please also describe the consequences to you and 
your investors if you
         or your subsidiaries: (i) do not receive or maintain such permissions 
or approvals, (ii)
         inadvertently conclude that such permissions or approvals are not 
required, or (iii)
         applicable laws, regulations, or interpretations change and you are 
required to obtain such
         permissions or approvals in the future.
8.       Disclose that trading in your securities may be prohibited under the 
Holding Foreign
         Companies Accountable Act if the PCAOB determines that it cannot 
inspect or investigate
         completely your auditor, and that as a result an exchange may 
determine to delist your
         securities.

9.       We note your disclosure on page 38 that Baird Medical does not believe 
that the 2022
         Supervisory and Administrative Measures for Production will have a 
material impact on
         its business operations. Please expand your disclosure to explain why 
you do not believe
         such regulations will have a material impact on your business 
operations, including any
         underlying assumptions.

10.      We note your response to comment 13. You concluded that the Earnout 
Shares did not
         qualify for equity treatment as the Earnout Shares provisions 
contained a change of
         control feature. Please address what consideration was given as to 
whether the Earnout
         Shares and corresponding change of control provisions represent an 
exercise contingency
         as addressed in ASC 815-40-15-7. Please also address what 
consideration you gave to the
         guidance in ASC 815-40-15-7A and 15-7B in determining the appropriate 
accounting for
         the Earnout Shares. Please specifically provide us your analysis of

12.      We note your revised disclosure in response to prior comment 17, which 
we reissue in
         part. In addition to disclosing the proportion of the microwave

Risks Related to Doing Business in China, page 104

13.      We note your response to prior comment 23, which we reissue in part. 
We note that your
         disclosure on pages 110 and 111 and elsewhere continues to state that 
the PRC
         government    intervenes to optimize China   s economy,    has    
implemented various
         measures to encourage economic growth,    and may    strengthen 
oversight    over your
         operations. Please revise your disclosure, including the disclosure 
noted above, to
         clearly describe any material impact that intervention or control by 
the PRC government
         has or may have on your business or on the value of your securities. 
Your disclosure
         should highlight separately the risk that the Chinese government may 
intervene or
         influence your operations at any time, which could result in a 
material change in your
         operations and/or the value of the securities you are registering. 
Also, given recent
         statements by the Chinese government indicating an intent to exert 
more oversight and
         control over offerings that are conducted overseas and/or foreign 
investment in China-
         based issuers, acknowledge the risk that any such action could 
significantly limit or
         completely hinder your ability to offer or continue to offer 
securities to investors and
         cause the value of such securities to significantly decline or be 
worthless. We remind you
         that, pursuant to federal securities rules, the term    control    
(including the terms
            controlling,       controlled by,    and    under common control 
with   ) means    the possession,
         direct or indirect, of the power to direct or cause the direction of 
the management and
         policies of a person, whether through the ownership of voting 
securities, by contract, or
         otherwise.

         other potential targets, including Company A and the three other

         when ExcelFin decided to expand its focus beyond the FinTech industry 
and reached out
         to its network of professional contacts. You also disclose that Mr.

or    packages    that
         were discussed at meetings without providing additional detail 
regarding the substance of
         those discussions and material terms of the relevant agreements. By 
way of example only,
         please expand your disclosure relating to the    financial package    
ExelFin received on
         April 10, 2023 and the    several proposed transaction structures    
discussed on May 15,
         2023.
16.      We note your response to prior comment 37, which we reissue in part. 
Please revise this
         section to include a discussion of the evolution of the key negotiated 
terms during the
         period between February 25, 2023 and April 3, 2023, including the 
multiple conference
         calls and drafts of the LOI that were exchanged on April 2 and April 
3, 2023. Your
         disclosure should discuss the negotiation of key terms, including but 
not limited to, the
         lock-up on shares, the change in the size of the board of directors, 
and the minimum cash
         condition. In your revised disclosure, please explain the reasons for 
such terms, each
         party's position on such issues, the proposals and counter-proposals 
made during the
         course of negotiations, and how you reached agreement on the final 
terms.
17.      We note your revised disclosure in response to prior comment 38, which 
we reissue in
         part. Please revise your disclosure to address the following issues:

                You disclose on page 184 that the initial proposal of a 
pre-transaction equity value of
              Baird Medical of $174 million was    consistent with ExcelFin 
management   s
              evaluation and due diligence of Baird Medical   s business as of 
the date the draft LOI
              was delivered, which was based on publicly available information, 
including Baird
              Medical   s valuation range set forth in the prospectus for its 
proposed Hong Kong
              IPO.    Please expand your disclosure relating to the underlying 
assumptions and
              methodology of ExcelFin management   s evaluation and Baird 
Medical   s proposed
              Hong Kong IPO and the valuation range included in the prospectus 
for such IPO.

                We note your revised disclosure on page 185 that ExcelFin   s 
management    further
              refined    the underlying assumptions in calculating a 
pre-transaction equity value of
              Baird Medical during the multiple conference calls and drafts of 
the LOI that were
              exchanged on April 2 and April 3, 2023. Please expand your 
disclosure with respect
              to each assumption that was    refined    and discuss how the 
Board used such
              assumptions, such as the net profits projections, the comparable 
company
              transactions and business plan, to reach its revised valuation. 
Please also discuss the
              evolution of the proposed valuation of Baird Medical during the 
multiple conference
              calls and draft LOIs that were exchanged on April 2 and April 3, 
2023, if applicable.
18.      We note your response to prior comment 39, which we reissue as we are 
not persuaded by
         your response. We further note that Item 4(b) of Form F-4 requires

         summaries. Alternatively, please provide a detailed legal analysis as 
to why these due
         diligence summaries are not materially related to your business 
combination transaction.
19.      With respect to the third bullet point of prior comment 40, we note 
your revised risk factor
         disclosure on page 136. Please revise to specifically note the unusual 
nature of the fee
         waivers. In addition, if you did not seek out the reasons why UBS and 
KeyBanc were
         waiving deferred fees, despite already completing their services, 
please clearly state so in
         your registration statement.
20.      We note your disclosure that "S&A compared Baird Medical to two

the assumptions selected
         for the    profitability profile    in your comparable companies

24.      We note your revised disclosure in response to prior comment 50. 
Please revise your
         disclosure to address the following issues:

                We refer to your disclosure on page 254 that (i) you initiated 
your plan for FDA
              marketing clearance in the U.S. for your microwave ablation 
medical device to be
              used for coagulation (ablation) of soft tissues, (ii) you have 
partially completed
              research and development for your soft tissue products in the 
U.S., and (iii) the FDA
              granted 510(k) clearance to commercially market your disposable 
microwave
              ablation needle and system. Please briefly clarify what you mean 
by    soft tissues   
              and specify the target indication(s) for which the medical 
devices that the FDA
              granted 510(k) clearance to treat, if applicable. We refer to 
various references to liver
              cancer, breast lumps and thyroid nodules. Please also disclose 
the current status of
              and your plans to complete your research and development for your 
soft tissue
              products in the U.S.

                We note your disclosure on page 255 that you have not yet begun 
the certification
              process or applied for certification in the E.U. for your breast 
lump and thyroid
              nodule product line and have only partially completed research 
and development for
              such products. However, you also disclose that you expect to 
launch such product
              line in 2025. Determinations of safety and efficacy are within 
the sole authority of the
              EU notified body pursuant to the E.U. Medical Devices Regulation. 
Given the status
              of your research and development and application status, it is 
premature for you to
              suggest that your breast lump and thyroid nodule products will be 
granted the CE
              Mark by 2025. Please revise your disclosure accordingly.

25.      We note your revised disclosure on page 272 in response to prior 
comment 56, which we
         reissue in part. We note your disclosure on page 272 that you    
engaged    three Grade IIIA
         hospitals, which appointed the principal researchers to design and 
conduct the clinical trial
         for your microwave ablation medical device for the treatment of 
thyroid nodules. Please
         revise to clearly state here and throughout the prospectus that, if 
true, Baird Medical
         sponsored the clinical trial and entered into collaboration agreements 
with various
         research institutions, universities and/or hospitals to conduct the 
clinical trial and identify
         such institution and its role for each relevant clinical trial.
26.      We note your disclosure on page 273 that you are currently conducting 
clinical trials for
         the treatment of breast lump and pulmonary nodules, but you also 
disclose on pages 277
         and 278 that the clinical trials for such target indications have not 
yet started. Please
         reconcile your disclosure accordingly. Please also expand your 
disclosure to discuss the
         status of such clinical trials, such as the enrollment of subjects,

         institution or university will provide technical services and conduct 
the clinical trials, if

27.      We acknowledge your revised disclosure on pages 275 through 280 in 
response to prior
         comment 56 relating to your thyroid nodule, breast lump, and pulmonary 
nodule clinical
         trials. Please revise your disclosure relating to each clinical trial 
to address the following
         issues, as applicable:

                Please clearly disclose the primary and secondary endpoints of 
your clinical trials, as
              applicable. We note your references to various    general 
research objectives    and
                 evaluation ind[ices]   ;

                Please clarify, if true, that you have conducted one clinical 
trial for the treatment of
              thyroid nodules that were conducted at three different hospital 
sites. If so, please
              clarify the number of subjects associated with each hospital 
site;

                Please revise to identify the    designated control medical 
product    referenced;

                Please revise your disclosure to discuss the data from the 
clinical trial, rather than
              drawing conclusions from the results, and specify the p-value in 
this section. We refer
              to your disclosure of the p-value on page 272;

                We note your disclosure on page 272 that you were    able to 
evaluate the safety and
              effectiveness of the trial product for thermal ablation treatment 
of benign thyroid
              nodules.    Please note that determinations of safety and 
efficacy are solely within the
              authority of the FDA and the relevant regulatory authorities. 
Therefore, please revise
              the prospectus to remove all references and/or implications of 
safety and efficacy,
              including the reference cited above;

                We note your disclosure that no    device defects    that could 
lead to adverse events
              occurred during the clinical trial. Please revise your disclosure 
to specify if any
              adverse events were observed with respect to your clinical trial, 
irrespective of any
              connection to a device defect; and

                Please revise this section to ensure that your disclosures are 
in plain English and are
              clear without reference to formulas for sample size calculations. 
Please also consider
              including your disclosure in narrative rather than tabular form.
28.      We note your revised disclosure to prior comment 57, which we reissue 
in part. While you
         disclose that Class II medical devices do not require clinical trials 
as part of their
         applications for certificate of registration, we note your disclosure 
relating to    formal
         reports    to be submitted to the NMPA or provincial MPA, the 24 to 36 
months of research
         and development, as well as the several clinical trials you have 
engaged in or are
         conducting. Please revise your disclosure to clearly state the 
regulatory requirements of
         the NMPA or the provincial MPAs to grant approval for the 
commercialization of medical
         devices.
