       Part I
       Item 3.D. Risk Factors, page 1

   1.                                                   In your summary of risk 
factors, disclose the risks that your corporate structure and being
                                                        based in or having the 
majority of the company   s operations in China poses to investors.
                                                        In particular, describe 
the significant regulatory, liquidity, and enforcement risks. For
                                                        example, 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 your securities to significantly decline or be 
worthless.
2.       Revise your risk factors to acknowledge that if the PRC government 
determines that the
         contractual arrangements constituting part of the VIE structure do not 
comply with PRC
         regulations, or if these regulations change or are interpreted 
differently in the future, your
         securities may decline in value or become worthless if the 
determinations, changes, or
         interpretations result in your inability to assert contractual control 
over the assets of your
         PRC subsidiaries or the VIEs that conduct all or substantially all of 
your operations.
3.       Given the Chinese government   s significant oversight and discretion 
over the conduct of
         your business, please revise to 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 your securities. 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 your securities to significantly decline or be 
worthless.
4.       In light of recent events indicating greater oversight by the 
Cyberspace Administration of
         China (CAC) over data security, particularly for companies seeking to 
list on a foreign
         exchange, please revise your disclosure to explain how this oversight 
impacts your
         business and your securities and to what extent you believe that you 
are compliant with
         the regulations or policies that have been issued by the CAC to date.
5.       Please update your disclosure in the risk factor regarding the Holding 
Foreign Companies
         Accountable Act on page 37 to reflect that the Commission adopted 
rules to implement
         the HFCAA and that, pursuant to the HFCAA, the PCAOB has issued its 
report notifying
         the Commission of its determination that it is unable to inspect or 
investigate completely
         accounting firms headquartered in mainland China or Hong Kong.
Item 4. Information on the Company
A. History and Development of the Company, page 45

6.       At the onset of Item 4, please disclose prominently that you are not a 
Chinese operating
         company but a Cayman Islands holding company with operations conducted 
by your
         subsidiaries and through contractual arrangements with variable 
interest entities (VIEs)
         based in China and that this structure involves unique risks to 
investors. If true, disclose
         that these contracts have not been tested in court. Explain whether 
the VIE structure is
         used to provide investors with exposure to foreign investment in 
China-based companies
         where Chinese law prohibits direct foreign investment in the operating 
companies, and
         disclose that investors may never hold equity interests in the Chinese 
operating company.
         Your disclosure should acknowledge that Chinese regulatory authorities 
could disallow

         this structure, which would likely result in a material change in your 
operations and/or a
         material change in the value of your securities, including that it 
could cause the value of
         your securities to significantly decline or become worthless. Provide 
a cross-reference to
         your detailed discussion of risks facing the company as a result of 
this structure.
7.       We note that the consolidated VIEs constitute a material part of your 
consolidated
         financial statements. Please provide in tabular form condensed 
consolidating schedule -
         depicting the financial position, cash flows and results of operations 
for the parent, the
         consolidated variable interest entities, and any eliminating 
adjustments separately - as of
         the same dates and for the same periods for which audited consolidated 
financial
         statements are required. Highlight the financial statement information 
related to the
         variable interest entity and parent, so an investor may evaluate the 
nature of assets held
         by, and the operations of, entities apart from the variable interest 
entity, which includes
         the cash held and transferred among entities. As part of your 
revisions, disclose the
         jurisdiction in which Libra Sciences Limited is incorporated or 
chartered.
B. Business Overview, page 48

8.       Provide prominent disclosure about the legal and operational risks 
associated with being
         based in or having the majority of the company   s operations in 
China. Your disclosure
         should make clear whether these risks could result in a material 
change in your operations
         and/or the value of your securities 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. Your disclosure 
should address how
         recent statements and regulatory actions by China   s government, such 
as those related to
         the use of variable interest entities and data security or 
anti-monopoly concerns, have or
         may impact the company   s ability to conduct its business, accept 
foreign investments, or
         list on a U.S. or other foreign exchange.
9.       Please disclose whether your auditor is subject to the determinations 
announced by the
         PCAOB on December 16, 2021 and whether and how the Holding Foreign 
Companies
         Accountable Act and related regulations will affect your company.
10.      Please revise your diagram of the company   s corporate structure, 
identifying the person or
         entity that owns the equity in each depicted entity, including voting 
and economic rights.
         Describe all contracts and arrangements through which you claim to 
exercise control that
         results in consolidation of the VIEs    operations and financial 
results into your financial
         statements. Identify clearly the entity in which investors are 
purchasing their interest and
         the entities in which the company   s operations are conducted. 
Describe the relevant
         contractual agreements between the entities and how this type of 
corporate structure may
         affect investors and the value of their investment, including how and 
why the contractual
         arrangements may be less effective than direct ownership and that the 
company may incur
         substantial costs to enforce the terms of the arrangements. Disclose 
the uncertainties
         regarding the status of the rights of the Cayman Islands holding 
company with respect to
         its contractual arrangements with the VIEs, its founders and owners, 
and the challenges

         the company may face enforcing these contractual agreements due to 
legal uncertainties
         and jurisdictional limits.
11.      Clearly disclose how you will refer to the holding company, 
subsidiaries, and VIEs 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. Refrain from using terms such as    we    or    
our    when describing
         activities or functions of a VIE. For example, disclose, if true, that 
your subsidiaries
         and/or the VIE conduct operations in China, that the VIE is 
consolidated for accounting
         purposes but is not an entity in which you possess majority voting 
power, and that the
         holding company does not conduct operations.
12.      Please revise your disclosure here to state that you are the primary 
beneficiary of the VIEs
         for accounting purposes. Please also disclose, if true, that the VIE 
agreements have not
         been tested in a court of law.
13.      Disclose each permission or approval that you, your subsidiaries, or 
the VIEs are required
         to obtain from Chinese authorities to operate your business and to 
offer securities to
         foreign investors. State whether you, your subsidiaries, or VIEs 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 the VIE   s 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,
         your subsidiaries, or the VIEs: (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.
14.    Provide a clear description of how cash is transferred through your 
organization. Disclose
       your intentions to distribute earnings or settle amounts owed under the 
VIE agreements.
       Quantify any cash flows and transfers of other assets by type that have 
occurred between
       the holding company, its subsidiaries, and the consolidated VIEs, and 
direction of transfer.
       Quantify any dividends or distributions that a subsidiary or 
consolidated VIE have made
       to the holding company and which entity made such transfer, and their 
tax consequences.
       Similarly quantify dividends or distributions made to U.S. investors, 
the source, and their
       tax consequences. Your disclosure should make clear if no transfers, 
dividends, or
       distributions have been made to date. Describe any restrictions on 
foreign exchange and
       your ability to transfer cash between entities, across borders, and to 
U.S. investors.
